Veterinary Medicine: How to feed a cat: Consensus statement to the veterinary community.

Veterinary Medicine: How to feed a cat: Consensus statement to the veterinary community.The American Association of Feline Practitioners (AAFP) released the AAFP Consensus Statement, "Feline Feeding Programs: Addressing Behavioral Needs to Improve Feline Health and Wellbeing" and accompanying client brochure to the veterinary community. The Consensus Statement, published in the Journal of Feline Medicine and Surgery, explores the medical, social, and emotional problems that can result from the manner in which most cats are currently fed. This statement focuses on "how to feed" because an often-overlooked aspect of feline health is how cats are fed. This Consensus Statement identifies normal feeding behaviors in cats. It provides strategies to allow these normal feline feeding behaviors, such as hunting and foraging, and eating frequent small meals in a solitary fashion, to occur in the home environment -- even in a multi-pet home. Allowing cats to exhibit these normal feeding behaviors regularly, can help alleviate or prevent stress-related issues such as cystitis, and/or obesity-related problems such as inactivity and overeating. Reducing stress with appropriate feeding programs can also help anxious cats, who in an attempt to avoid other pets in the household, may not access the food frequently enough and lose weight. Currently, most pet cats are fed in one location ad libitum, or receive one or two large and usually quite palatable meals daily. In addition, many indoor cats have little environmental stimulation, and eating can become an activity in and of itself as this current type of feeding process does not address the behavioral needs of cats.Appropriate feeding programs need to be customized for each household, and should incorporate the needs of all cats for play, predation, and a location to eat and drink where they feel safe. The Consensus Statement also highlights the importance of feeding programs, which should be designed to consider whether they are indoor-only or have outdoor access, live in multi-pet households, or are aged or debilitated.These feeding programs in many cases include offering frequent small meals using appropriate puzzle feeders, forage feeding (putting food in different locations), multiple food and water stations, and in some instances, automatic feeders.

How to protect a pig farm from African Swine Fever.(ASF).

 How to protect a pig farm from African Swine Fever.(ASF).


ASF is all about contact ASF is spread by contact. Far less by the pig breathing the virus in as in Classical Swine Fever, so it should be easier to prevent and control.

 Think ‘contact’ in everything you plan to do and subsequently carry out on the premises. The contact is not just pig to pig, but what we humans do by allowing the ASF virus in through contact on the clothing equipment, vehicles, food deliveries, breeding stock and every other visit by an ‘outsider’ to or into your vulnerable farm premises.

 1) Keep everybody off your farm You will need discipline and tact to do this effectively. Quite brutally, you do not know where they have been! So do not risk it. The only permissible person as routine is the pig veterinarian and of all people he should take the necessary precautions.

Even so, do not allow his vehicle on to the farm. Have a parking spot outside the perimeter and if necessary, help carry his equipment in for him.

 There will be skilled artisans of course, electricity, roofing, plumbing, etc. who will need access. Keep their vehicles off the farm too and make it clear beforehand (for the sake of good relations) that they will have to use farm overalls and footwear and need their equipment mist-sprayed.

 2)An unbreakable farm perimeter defense. For the delivery of replacement stock (semen is safer than live pigs) and the collection of finished pigs, have designated areas on or just outside the farm perimeter.

On no account allow ‘helpful’ drivers (offering to assist with the loading) on to the premises. The same with bulk or bagged food and supplies.

 As soon as you can, set up food reception bulk bins using your own inlet hoses, not theirs; a covered site for bags and other bulky deliveries. All 3 on the farm boundary, for later inward transmission by your own staff, never theirs.

Agribusiness:How to get small piglets to eat more feed.

Agribusiness:How to get small piglets to eat more feed.What influences feed intake of small piglets? Researchers from the Netherlands looked at the effects on feed intake and feeding behaviour of many aspects of feed in more detail. The scientists, attached to Wageningen University and Research, published about the research in the journal Applied Animal Behaviour Science. They describe a trial that tested the feeding behaviour of suckling piglets when different diets were supplied to them. The hypothesis of the study was that presentation of the feed in a more diverse form, by varying multiple sensory properties of the feed, stimulates pre-weaning feed intake. Stimulating solid feed intake in suckling piglets is important to facilitate the weaning transition, exemplified by the positive correlation between pre- and post-weaning feed intake. 2 different diets tested by piglets Piglets received ad libitum feed from 2 days of age in 2 feeders per pen (choice feeding set-up).Feed A was an experimental diet from the university’s Animal Nutrition Group. Extruder settings intendedly varied during production, resulting in differences in pellet texture, length and hardness to create diversity within feed A. Feed B is a commercial diet, called Baby Big XL, from Coppens Diervoeding in the Netherlands. Feed B was a 14-mm diameter pellet, with a length of 10-20 mm and a hardness of 6.8 kg.Feeding behaviour was studied by weighing feed remains and by live observations. Observations were also used to discriminate ‘eaters’ from ‘non-eaters’. In addition, eaters were grouped into different eater classes (i.e. good, moderate and bad). Provision of feed A and B increased pre-weaning feed intake by 50% compared to provision of feed A only (with and without additional flavours). Piglets receiving feed A and B had no overall preference in terms of feed intake for either feed A or B, indicating pre-weaning feed intake increased by an enhanced intake of both feeds. These results supported the researchers’ hypothesis that the more diverse the feeds provided in terms of sensory properties (e.g. ingredient composition, texture), the greater the intake will be. The reason for this is expected to be sensory-specific satiety and/or piglets’ intrinsic motivation to explore.

AGRIBUSINESS: Print-Arome for flavor imprinting.

AGRIBUSINESS: Print-Arome for flavour imprinting. Print-Arome is flavor formulated with essential oils.Dosed in the sows and post-weaning diets generate an “imprinting” effect in the piglets. This effect familiarizes the piglets with its scent and facilitates the introduction to solid food. As a result, it increases feed intake, weight gain and reduces health problems associated with early weaning. It improves feed intake by 95% while it reduces stress by 92%. Print-Arome.

AGRIBUSINESS: Expanding the reach of flavour imprinting in piglets.

AGRIBUSINESS: Expanding the reach of flavour imprinting in piglets. An aroma, based on essential oils, is capable of generating an imprinting effect in piglets that can boost their introduction to solid feed after weaning and improves their performance. Combining this with spray dried porcine plasma could bring even further benefits post-weaning. Early weaned piglets are subject to a great deal of stress and have to adapt abruptly to a new diet, which delivers a great physiological challenge. As a result, during the first week after weaning, piglets typically have a low feed intake and a growth decrease that has an impact on the animal’s gut morphology, increasing the risk of post-weaning diarrhoea and consequently affecting the animals subsequent performance. Supplementing sow and post-weaning diets with Print-Arome, a flavour formulated with essential oils, has an imprinting effect in piglets. This effect familiarises the piglets with its scent and facilitates the introduction to solid feed. The transfer of dietary information from mother to offspring with the essential oils flavour has been proven to successfully improve feed intake and weight gain of piglets at weaning. Likewise, spray dried porcine plasma (SDPP) is also a common feed ingredient used for similar objectives; included in weaning diets to improve feed intake, post-weaning performance and reduce diarrhoea incidence.

Agribusiness: A good start is vital for healthy piglets.

Agribusiness: A good start is vital for healthy piglets.Raising healthy piglets from start through weaning is a challenge not to be underestimated, impacting performance and health at later stages. Sudden change in dietary regimens and management at weaning puts a heavy burden on the animal’s immature digestive system. This leads to a disturbed immune system and microbiota, and increased susceptibility to diseases. Stress already starts at birth, a crucial period filled with risks: piglets must be born strong and healthy and remain that way. Once born, piglets encounter several hurdles: piglets suffer from all kinds of pathogenic challenges with an immature immune system. There is a significant and immediate demand on the gut to digest and absorb nutrients efficiently to maintain a high growth rate. Intestinal epithelial cell integrity is of prime importance considering that this epithelium is responsible for absorption of water, electrolytes, and nutrients. Not to forget the beneficial microbiome that must establish itself as soon as possible to guarantee a fully functioning intestinal tract. Once the piglet could manage these hurdles, another event, considered as a major stressor, takes place: weaning. Although technological improvements in housing, nutrition, and management are available to minimise the stress, piglets are weaned at unphysiologically early ages. The sudden change in dietary regimens at weaning places a heavy burden on the immature digestive system of the piglet. The gastro-intestinal tract is affected by a change in microbiome, mechanical damage, and inflammation as reaction to the stresses (social, nutritional, handling) of weaning. The effects are aggravated by the immature immune system which has not developed a full response to cope with pathogens, resulting in disease . It is clear impairment of the normal gut and immune function, leading to diarrhoea and even death, which needs to be avoided.

AGRIBUSINESS: 4 piglet parameters for lifetime performance.

             AGRIBUSINESS: 4 piglet parameters for lifetime performance.

 Genetic selection is leading to larger litters of piglets born with lowered levels of physiological maturity. As this trend amplifies an evolutionary strategy in swine favouring survival of the fittest, it presents negative performance and animal welfare implications.

 Sow Peripartal Syndrome is a complex web of interactions affecting sows and piglets during the peripartal period. At least four parameters are present at birth that can ultimately determine piglets’ lifetime performance.

The following is an update on research underway to managing the syndrome. Alive at birth While genetic selection has increased the total number of pigs per litter, the number of pigs born alive has not increased at the same pace.

 Heat Stress is a physiological response to high environmental temperatures, where the animal is out of its thermo-neutral zone and can no longer effectively regulate its body temperature. Consequently, animal health, well-being and performance are negatively affected.

 

AGRIBUSINESS: Hens that lay human proteins in eggs offer future therapy hope..

AGRIBUSINESS: Hens that lay human proteins in eggs offer future therapy hope.Chickens that are genetically modified to produce human proteins in their eggs can offer a cost-effective method of producing certain types of drugs, research suggests. The study -- which has initially focused on producing high quality proteins for use in scientific research -- found the drugs work at least as well as the same proteins produced using existing methods. High quantities of the proteins can be recovered from each egg using a simple purification system and there are no adverse effects on the chickens themselves, which lay eggs as normal. Researchers say the findings provide sound evidence for using chickens as a cheap method of producing high quality drugs for use in research studies and, potentially one day, in patients. Eggs are already used for growing viruses that are used as vaccines, such as the flu jab. This new approach is different because the therapeutic proteins are encoded in the chicken's DNA and produced as part of the egg white.

RESEARCH: New skin test detects prion infection before symptoms appear.

RESEARCH: New skin test detects prion infection before symptoms appear. Prions can infect both humans and animals, causing Creutzfeldt-Jakob disease (CJD) in humans, mad cow disease in cattle, and chronic wasting disease in elk and deer. The infectious, misfolded protein particles often go undetected as they destroy brain tissue, causing memory loss, mobility issues, and ultimately death. Preclinical detection of prions has proven difficult, but new research suggests skin samples hold early signs of prion disease that precede neurologic symptoms. Currently, a definitive diagnosis of Creutzfeldt-Jakob disease is dependent on the examination of diseased brain tissue obtained at biopsy or autopsy. It has been impossible to detect at the early preclinical stage," said Wenquan Zou, MD, PhD, associate professor of pathology at Case Western Reserve University School of Medicine. In a ground-breaking study published in Nature Communications, Zou and an international team of researchers successfully used two methods to detect prions in skin samples collected from inoculated rodents. The study provides the first proof-of-concept evidence that readily accessible skin samples could be used to detect prion disease early -- before clinical symptoms appear. In the new study, Zou and colleagues successfully detected prions in rodent skin samples as early as two weeks post-infection. They also detected prions in the skin of uninoculated rodents that were housed alongside inoculated cage mates, demonstrating that prion transmission can occur between cohabiting rodents.

RESEARCH: Eyes of Creutzfeldt-Jakob disease( CJD) patients show evidence of prions.

RESEARCH: Eyes of Creutzfeldt-Jakob disease patients show evidence of prions. Creutzfeldt-Jakob disease (CJD) is a rare, degenerative, fatal brain disorder. It affects about one person in every one million per year worldwide; in the United States there are about 350 cases per year. CJD belongs to a family of human and animal diseases known as the transmissible spongiform encephalopathies (TSEs) or prion diseases. A prion—derived from “protein” and “infectious”—causes CJD in people and TSEs in animals. Spongiform refers to the characteristic appearance of infected brains, which become filled with holes until they resemble sponges when examined under a microscope. CJD is the most common of the known human TSEs. CJD usually appears in later life and runs a rapid course. The typical onset of symptoms occurs at about age 60, and about 70 percent of individuals die within one year. In the early stages of the disease, people may have failing memory, behavioral changes, lack of coordination, and visual disturbances. As the illness progresses, mental deterioration becomes pronounced and involuntary movements, blindness, weakness of extremities, and coma may occur. There are three major categories of CJD. 1)In sporadic (sCJD), the disease appears even though the person has no known risk factors for the disease. This is by far the most common type of CJD and accounts for at least 85 percent of cases. 2)In hereditary CJD, the person may have a family history of the disease and test positive for a genetic mutation associated with CJD. About 10 to 15 percent of cases of CJD in the United States are hereditary. 3) in acquired CJD, the disease is transmitted by exposure to brain or nervous system tissue, usually through certain medical procedures. There is no evidence that CJD is contagious through casual contact with someone who has CJD. Since CJD was first described in 1920, fewer than one percent of cases have been acquired CJD. A type of CJD called variant CJD (or vCJD) can be acquired by eating meat from cattle affected by a disease similar to CJD called bovine spongiform encephalopathy (BSE) or, commonly, “mad cow” disease. A new study, researchers at University of California San Diego School of Medicine with colleagues at the National Institutes of Health and UC San Francisco, report finding tell-tale evidence of the condition's infectious agent in the eyes of deceased sCJD patients, making the eye a potential source for both early CJD detection and prevention of disease transmission. In the November 20 issue of the journal mBio, co-corresponding author Christina J. Sigurdson, DVM, PhD, professor of pathology at UC San Diego and UC Davis, and colleagues discovered high levels of prions in the eyes of 11 deceased patients, all with confirmed sCJD. Almost half of sCJD patients develop visual disturbances, and its a known fact that the disease can be unknowingly transmitted through corneal graft transplantation.

DISEASE TRANSMISSION AND BIOSECURITY PROTOCOLS.

BIOSECURITY.  Following simple but specific protocols everyday to positively influence animal health, food safety and public health.

 What are the basic protocols in biosecurity? READ

 Biosecurity basically entails, prevention of pathogens from entering premises to ensure there is no disease incidence, and curtail spread of diseases in cases of outbreaks.

  Pathogens are disease causing microorganisms that usually have devastating effect on animals, resulting in decreased production and death in severe cases.  Pathogens can be bacteria, viruses, fungi and prion.

.  The animal kingdom is riddled with several pathogens that wreck havoc on these animals irrespective of specie.  These pathogens are also of importance to man, especially when these cause zoonotic diseases.

 Zoonotic diseases are spread from animals to man, and sometimes there is a reverse zoonoses where man actually spreads the disease to their animals.

  Route of transmission.  The basic routes are:  Direct contact.  Aerosol.  Oral.  Formites.  Vector borne  Zoonoses.  Reproduction.  Environmental contamination.

  Mode of transmission.  Direct contact ;disease spread by contact with open wounds, mucous membrane of an infected animal or its secretions/tissue fluids.

Disease can also spread through contact with reproductive fluid(blood, urine and saliva) during breeding, or from mother to offspring.

  Aerosol; droplets containing the pathogenic agent travel in air and are inhaled as respiratory droplets by animals

 Oral; ingestion of the pathogenic agent from contaminated feed ,chewing/licking contaminated objects in environment and water.

 Formites; spread of the pathogen through contact with inanimate objects contaminated by infected animals.

Man can act as formites by transferring these pathogens in through soiled boots, gloves or tools.

An international study conducted by Unilever reveals that more than a third of consumers (33%) are now choosing to buy from companies they believe are producing in accordance with ecological principles, and the majority of consumers nowadays expect that products they buy fulfill high social, ecological and ethical standards (source: Unilever). 

 When buying, consumers are wondering: 'Is this product good for my family and me? Is this produced in a healthy way? Although the label claims it is organic, is it really? Is it possible for a false statement to be on a label? Is the price I’m paying justified? Although there are already many certificates that seem to guarantee the origin of the product, there is only one which has definitive rules for growers to follow. 

The GLOBALG.A.P. is a food safety standard developed to regulate food production processes from micro to macro level of producing. GLOBALG.A.P. certificate can provide the customer a complete transparency of the food production process, from the farm to its final product.

RESEARCH: Dry-cured ham bones -- a source of heart-healthy peptides.

RESEARCH: Dry-cured ham bones -- a source of heart-healthy peptides.Drinking bone broth is a recent diet fad that proponents claim fights inflammation, eases joint pain and promotes gut health. Simmering animal bones in water releases collagen and other proteins into the broth that may have health benefits, although more research is needed to validate these claims. Now, a new study in ACS' Journal of Agricultural and Food Chemistry has shown that ham bones contain peptides that could have cardioprotective effects. During cooking and digestion, proteins from animal bones can be broken down into smaller pieces, or peptides, that have different properties than the intact protein. For example, some peptides from collagen act as antioxidants or inhibitors of disease-related enzymes. To see if Spanish dry-cured ham bones could be a source of beneficial peptides, Leticia Mora and colleagues ground up the bones and simulated conditions of cooking and human digestion. Then, they examined whether the bone samples could block the activities of several enzymes involved in cardiovascular disease. The researchers found that the bone peptides, most of which were derived from collagen and hemoglobin proteins, inhibited the enzymes even after heating and simulated digestion. In fact, these treatments released additional bioactive peptides, suggesting that the use of ham bones to make broths and stews could have a positive impact on cardiovascular health.

AGRIBUSINESS: Rising temperatures may safeguard crop nutrition as climate changes.

AGRIBUSINESS: Rising temperatures may safeguard crop nutrition as climate changes.Hotter temperatures may offset the negative effects of higher carbon dioxide levels on seed quality.Recent research has shown that rising carbon dioxide levels will likely boost yields, but at the cost of nutrition. A new study in Plant Journal from the University of Illinois, U.S. Department of Agriculture Agricultural Research Service (USDA-ARS), and Donald Danforth Plant Science Center suggests that this is an incomplete picture of the complex environmental interactions that will affect crops in the future -- and rising temperatures may actually benefit nutrition but at the expense of lower yields. Two years of field trials show that increasing temperatures by about 3 degrees Celsius may help preserve seed quality, offsetting the effects of carbon dioxide that make food less nutritious. In soybeans, elevated carbon dioxide levels decreased the amount of iron and zinc in the seed by about 8 to 9 percent, but increased temperatures had the opposite effect.Iron and zinc are essential for both plant and human health.

RESEARCH : Plants smell different when attacked by exotic herbivores.

RESEARCH : Plants smell different when attacked by exotic herbivores.Plants emit odors in response to herbivory. A new study reveals that the odor bouquet changes depending on the type of enemy that attacks the plant. To the surprise of the researchers involved, native plants emit a special odor bouquet when they are attacked by exotic herbivores.

RESEARCH :HOW PLANTS SMELL.

RESEARCH :HOW PLANTS SMELL.Plants don't need noses to smell. The ability is in their genes. Researchers have discovered the first steps of how information from odor molecules changes gene expression in plants. Manipulating plants' odor detection systems may lead to new ways of influencing plant behavior. Plants detect a class of odor molecules known as volatile organic compounds, which are essential for many plant survival strategies, including attracting birds and bees, deterring pests, and reacting to disease in nearby plants. These compounds also give essential oils their distinctive scents.

AGRIBUSINESS: Body-painting protects against bloodsucking insects.

AGRIBUSINESS: Body-painting protects against bloodsucking insects. A study by researchers from Sweden and Hungary shows that white, painted stripes on the body protect skin from insect bites. It is the first time researchers have successfully shown that body-painting has this effect. Among indigenous peoples who wear body-paint, the markings thus provide a certain protection against insect-borne diseases. Most of the indigenous communities who paint their bodies live in areas where there is an abundance of bloodsucking horseflies, mosquitoes or tsetse flies. When these insects bite people there is a risk of bacteria, parasites and other pathogens being transferred. The study shows that body-painting provides protection against the insects. A brown plastic model of a human attracted ten times as many horseflies as a dark model painted with white stripes. The researchers also found that a beige-coloured plastic figure used as a control model attracted twice as many bloodsuckers as the striped model.

VETERINARY MEDICINE: Transmission of antibiotic resistant E. coli mapped in wild giraffe social networks.

VETERINARY MEDICINE: Transmission of antibiotic resistant E. coli mapped in wild giraffe social networks.A team has shown that antibiotic-resistant Escherichia coli bacteria in wild giraffes most likely come from anthropogenic sources, such as local cattle herds and humans. The team from the University of Minnesota has shown that antibiotic-resistant Escherichia coli bacteria in wild giraffes most likely come from anthropogenic sources, such as local cattle herds and humans. The research is published in Applied and Environmental Microbiology. They found that the majority of antibiotic resistance genes identified in giraffe E. coli had been previously identified in E. coli from both humans and domestic cattle in East Africa. Giraffes three months of age or younger were more likely to harbor antibiotic resistant E. coli than other age groups. This is a surprise as giraffe neonates nurse from their mothers exclusively and interact minimally with other group members, leading to a prediction they would have low exposure to resistant bacteria and residual antibiotics in their environment. The result suggest there may be competition between antibiotic resistant and susceptible E. coli strains in the giraffe neonatal gut, with resistant E. coli having a selective advantage.

VETERINARY MEDICINE: Feline morbilli virus.

VETERINARY MEDICINE: Feline morbilli virus. Feline morbillivirus (FeMV) was first reported in domestic cats in Hong Kong and China in 2012, and has since has been detected in Japan, Europe and the Americas. It was named as the seventh species in the genus Morbillivirus, alongside important pathogens of humans and animals such as measles virus and canine distemper virus. Despite a widespread distribution, like FcaGHV1 it is unclear whether FeMV causes disease in cats. Of particular interest to the veterinary community, however, is a link that has been suggested in several reports between FeMV and tubulointerstitial nephritis, the pathological manifestation of feline Chronic kidney disease.
