ALGAE; AN ALTERNATIVE TO ANTIBIOTICS.

The fight to reduce antibiotic use in farm animals because of its impact on human health is still raging on and the ban of antibiotics use in some countries have spurred research on alternatives. Additives and certain supplements have been incorporated into production all with various results.The use of prebiotics and probiotics have also been incorporated to achieve a desired healthy status coupled with growth and development. The latest series of research involves use of seaweeds and water hyacinth,the benefits and methods of incorporation have been discussed in earlier posts.There is a new angle to the use of algae(sea weeds) in production and as a biosecurity protocol.A pig farm is limiting its antibiotic use by incorporating seaweed to feed and also a means of biosecurity; Benoît and Olivier Balusson, owners of a farrow-to-finish farm in Britanny, France, have embarked on an exciting mission:how to decrease antibiotics as much as possible? The farm applies a range of strategies, some of which involve algae. Benoît and Olivier Balusson farm 1,900 sows in Britanny, an area of France which has around 80% of the country’s pigs. The farrow-to-finish unit is weaning just short of 30 pigs/sow/year which is commendable for such a large unit. Antibiotics are a big thing for Balusson farm – the farm aims to use as few as possible. Currently only 2 antibiotics can be used on the Balusson farm. Amoxycillin is sometimes injected in piglets before weaning to manage arthritis. Also, trimethoprim/ sulfamethoxazole can be added to the drinking water to control streptococci, if necessary. Ideally, however, antibiotic usage should be reduced further. In order to achieve that, an overarching strategy is being applied. This starts with creating the right conditions for a healthy environment, i.e. having high quality buildings with well-insulated rooms, decent building materials, healthy water as well as the availability of alternative health strategies, like e.g. vaccination. This is where the Balusson farm takes a different approach than most, as seaweed (algae) often form a key element in both their feed additives as well as hygiene products. Algae form the basis for instance for a mycotoxin binder – associating algae with clay and with other adsorbent materials, the company’s MT.x+ was created. For the Balusson farm, mycotoxin contamination is a widespread problem in cereals, so the binder is routinely added to the rations. In addition, algae-derived products also play a central role in piglet feed around weaning. At Balusson farm, this takes place at 21 days of age (on average at 6 kg). To reduce the effects of stress and to boost immunity levels, the farm provides Searup for 3 to 5 days in the weaner feed. The product, combines the action of immunomodulating Marine Sulfated Polysaccharides (MSP), vitamins and amino acids. According to the company’s website, immunomodulating MSP contribute to a better immune response thanks to the activation of specific receptors of the innate immune system. MSPs also have another function as they are observed to stimulate the secretion of protective mucin in the intestine. This forms the basis of the product Ecopiglet, which combines algae with micronised clays, all intended to reduce digestive problems. At the Balusson farm, the product is sprinkled on the heat pads from day 5. Algae also have a role to play in enhancing the farm’s hygiene status. When algae extracts are mixed with selected minerals and oils, as well as with montmorillonite, a powerful and dried and micronised clay, a very hygroscopic powder is created (marketed as Mistral). It is used in various moments on the farm. Newborn piglets get dunked in a tub of the powder at birth, to help them dry off quicker. This way they suckle faster.At weaning, when the piglets are mixed, the strategy has a role to play as the product’s aroma is perceived to be pleasant. Dusting piglets with it masks the piglets’ own smell and so reduces fighting and hence stress. After insemination, the powder is applied around the vulva to ensure optimal hygiene.Hygiene is certainly not compromised by Balusson’s take on castration – the farm doesn’t castrate. This has resulted in better production efficiency. culled from pigprogress.

BOAR STUD FARM AND ARTIFICIAL INSEMINATION.

Artificial insemination cooperative Cobiporc opened a large and efficient new boar stud for 300 male animals working on the principle that With modern knowledge and techniques, it is possible to keep diseases out. The new stud, developed and owned by French cooperative Cobiporc and taken into use in February 2015, houses in total 300 boars and is ready for the future. Cobiporc is an artificial insemination (AI) cooperative headquartered in the heart of Brittany, France. The cooperative has 1,800 pork producing customers in Brittany and its neighbouring regions of Lower Normandy and Pays de la Loire. The organisation holds about 60% of the total AI market in the west of France, and about 40% in the whole of France. Its genetics are 80% Piétrain or Duroc-Piétrain, animals with a generally low fat rate. The new boar stud replaces three other sites, which together had about 350 boars. The farm is U-shaped. On the left and on the right side are the boar quarters, with 15 rooms of 20 pens, one pen per boar of 2x3 metres, equipped with solid feeding systems, central ventilation and geothermal heating. In the middle, centrally located, is the collection area – with an adjacent laboratory. Bio security Several elements can be a source of contamination – air, animals, people and equipment – and for each a large protocol has been set up in order to avoid it.A modern filtration system has been applied to filter all incoming air. Particles of very small size will be caught so that the particles cannot enter the farm. "We filter out 99.5% of everything that comes in," explains Trelhu. Inside the farm building there is an under pressure, so automatically all air is drawn in through the filters. Interestingly, a good air quality inside the building contributes to a better hygiene and health status of the boar stud. One of the aspects of better air quality starts underneath the pig house – in the manure pens, as the goal is to get urine and faeces out as quickly and efficiently as possible. Inside the barns this happens by manually moving about 2 kg of daily faeces per boar into a separate hole in the corner of each pen. Underneath the pen, the slurry pit has two slopes. Across the breadth of the room, slopes of the slurry pit rises by 10% to either side from the middle; across the length of the room the slurry pit slopes up by 1.5% all the way up to the end. This ensures all urine to flow gently towards a central collection point underneath the farm. At the same time, underneath the floor, there is also an automatic scraping device, supplied by French pig cooperative Cooperl, that will push any faeces of the boars once a day in the opposite direction of the urine – up the slope of 1.5%. This way a daily separation of solid and liquid manure is ensured. The solid manure can be used as fertilizer, the liquid manure can directly be applied on the land, and the air inside the pig house is relatively clean. The pigs are being continuously tested for their health quality. Upon entrance, they go into a seven-week quarantine and all their blood values are tested. In addition, every week one-fifth of all the boars get their blood tested as well, this means that in about three months the Cobiporc team has checked the entire boar population for diseases – this includes Aujeszky's Disease (pseudorabies), brucellosis, PRRS and swine influenza. People are required to shower upon entrance and wear specific clothes for this farm. There is a different shower sluice for the laboratory staff and the boar caretakers. Not only inside is biosecurity a hot issue – outside the boar stud the biosecurity protocol goes further. After quality control checking (more about that later), the packed semen is picked up by the same dedicated van, which does nothing else but bring the semen from this facility to the central distribution building of Cobiporc near Rennes, the capital of Brittany, about 30 km down the road. In this place, all semen from all other stations are also combined, after which the right packaging can follow and further distribution to pig breeders follows. The van is the only transport vehicle that is allowed to enter the boar stud's. (story from materials from pig progress.)

PSEUDO-RABIES!!!

A large number of swine-producing 
countries have eradicated the presence of pseudorabies, also known as Aujeszky’s Disease. Aujeszky’s Disease can be found throughout the world, especially in regions with dense swine populations including South America, Asia and Europe. Countries such as Germany, Austria, Sweden, Denmark, the United Kingdom, Canada, New Zealand and the United States have eradicated the disease from their domestic swine populations in the late nineties. China on the other hand has experienced an unprecedented outbreak since 2011. Vaccination proves to be an important tool to control PRV. Pseudo rabies virus (PRV), the causing agent of Aujeszky’s Disease, is an extremely contagious herpes virus that causes respiratory disease and reproductive problems, including abortions and stillbirths in breeding swine. In piglets, PRV can cause coughing, sneezing, fever, constipation, depression, seizures, ataxia, circling and excess salivation, with mortality in piglets less than one month of age being close to 100%. Occasional death losses in breeding and finishing pigs can also occur. The virus is transmitted through nasal and oral secretions, food, water, and the environment. It can also be carried on vehicle wheels, including tyres or buggy wheels, boots and clothing. The incubation period is commonly two to five days, with nasal and oral excretion and, in adult swine, vaginal, preputial, and/or milk secretion coincident or just preceding any primary symptoms. Additionally, adult Aujeszky positive swine may harbour the virus without showing clear signs. The virus can live in humid air and non-chlorinated water for up to seven hours; and in the soil, on clothing, and faeces for up to two days. Dogs, cats, and racoons can physically transmit the virus between farms, but usually the virus causes death in these animals. PR viruses comprise a single serogroup. However, both vaccine and wild-type viruses can be differentiated into groups by using combinations of physical and biological markers. Vaccination with modified live marker vaccines is a useful tool in controlling the disease and PRV has been eradicated in many countries by the use of modified live vaccines.

BIO SECURITY MEASURES FOR SUCCESS IN THE POULTRY VALUE CHAIN.

BIOSECURITY.  Following simple but specific protocols everyday to positively influence animal health, food safety and public health.  What are the basic protocols in biosecurity?  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.  Pathogens .  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.  Fomites.  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.  Fomites; spread of the pathogen through contact with inanimate objects contaminated by infected animals. Man can act as fomites by transferring these pathogens in through soiled boots, gloves or tools.  Vector; some insects transfer these pathogens from one animal to another through bites.  Zoonoses; these pathogens are transferred from animals to man.  Environmental contamination is key in transmission as some of these pathogens remain infective in the environment for specific periods, thus establishing a foci of infection the area .  Biosecurity procedures  These are simple ,everyday practices to prevent entry of diseases and spread of diseases.  The protocol must be tailored to your farm setting, the type of pathogens affecting your type of animals and public health implication.  The basic biosecurity plan can be broadly divided into 1) isolation,2) cleaning and disinfection 3) waste disposal.  The chemicals to be used will depend on the targeted pathogen,to ensure we get result.  Steps in biosecurity. Isolation.  Isolation; this refers to keeping these pathogens out by following these steps 1)wearing personal protective equipment which could be disposable or reusable. These include boots, gloves, outer wear and masks/nose guards.  Provision of clean, sterilized clothes.  Prevent entry into animal housing.  Quarantine new animals to farm for at least a month.  Creation of a safe zone in the premises, where there visitors such as veterinarians can change to protective clothing before they have access to animal housing.  Isolate sick animals .  Screen farm premises to prevent entry of wild animals, birds, rodents and reptiles.  Cleaning, washing and disinfection.  Cleaning ,washing and disinfection; cleaning refers to removing debris, dirt and waste from animal housing prior to washing with soap/detergent and then disinfecting the premises.  This procedure also done for tools and implements. Egg trays, feeders/drinkers are also cleaned, washed and disinfected.  Foot bath/tyre dips are also classed here; where there is a provision of a foot dip with disinfectants at the entrance of the animal housing, while the tyres of vehicles coming to the facility are sprayed with disinfectant.  Hand washing points must be on the premises; when you come in you wash hands and sanitize hands.  Water sources such as tanks, containers are washed and sanitized  Waste disposal. Waste disposal/handling is a major route of spread of diseases, thus biosecurity practices must include proper management. Waste should be packed at regular intervals and treated with appropriate chemicals/disinfectants before disposal. This is to ensure that what ever pathogen is in the waste does not persist in the environment. When waste is to be used as manure, these should be bagged and stored neatly, and the area constantly cleaned. Composting the waste in a secluded section on farm is the best practice.  Disinfectants  The disinfectant to be used in animal facility must be non corrosive, non irritating, does not taint equipment, non toxic, have wide spectrum of use and easy to use.  There are basically 9groups that are of benefit; aldehyde group, quaternary ammonium, oxidizing agents , alcohol, hypochlorites,phenols,iodophors, chlorhexidene and peroxide.  The disinfectant of choice will depend on the pathogen in question and nature of case.  Thank you.

MORE BIRD FLU OUTBREAKS IN FRANCE!!!

FRANCE - Following the detection of three avian influenza outbreaks in Dordogne, three more outbreaks have been confirmed in Landes and Dordogne. The new outbreaks were detected after increased surveillance was put into place across France, including active surveillance of clinical signs of avian influenza in sensitive species. Abnormal mortality levels detected by farmers have also led to systematic sampling. The confirmed outbreaks, which took place in guinea fowl and ducks in Landes and ducks in Dordogne, a press release from the French agriculture ministry said that other outbreaks were suspected. Protection zones, surveillance, biosecurity and stamping out of the disease on the affected farms have been used to try and prevent the virus spreading. The issue of biosecurity with active surveillance is key to curb the spread of the virus and the issue of early reporting when there is a high number of mortality with a short period ,is also very important. story credit; poultry site.

SIGNS OF BIRD FLU IN MAN.

The bird flu virus has been know to affect man and causing death in some of those affected.The major means of infection is close contact with affected poultry such as handling and processing .The issue of bio security on farms can not be over emphasized, the use of foot dips,tyre dips and hand washing with stipulated disinfectants are essential for safety.The procurement of healthy birds from reliable sources is also vital in the biosecurity protocol. The incubation period is usually 3-7 days after contact with infected poultry. Signs include;A sudden high temperature of 38C or above,a dry, chesty cough, headache, tiredness,inappetence, sore throat, runny nose, muscle and joint pain, stomach upset, diarrhoea and sore throat. The other signs include pneumonia, respiratory distress which is followed by multiple organ failure resulting in death. Prevention; 1) wash hands after handling poultry. 2) avoid contact with wild birds. read more

Health management and bio security on farms.

The spread of avian influenza can be curbed using strict bio security measures,these will include cleaning,washing and regular disinfection of farm site.

 There are various chemicals that have virucidal potency that can be used to disinfect and decontaminate farm premises. One of such is virkon s,proven to be very effective against bird flu,along side other pathogens.

 The use of virkon S can not be overemphasized because of the tremendous success it has achieved in farms,hospitals food industry etc. There are various applications for the virkon s in various sectors,but we will focus on its uses in the farm.

DISINFECTANTS USED IN BIRD FLU OUTBREAK.

Disinfectants that are used for bio security in poultry are enormous but only 2 disinfectants have been proven to kill the bird flu virus.These disinfectants are virkon and virocid, they have been used in various outbreak in numerous countries with 100% efficacy. Virocid is the world’s most powerful disinfectant, as it achieves 99.9% microbial eradication It is all about avoiding pathogens building up to dangerously high levels. At these high levels, the pathogens can cause serious health problems for the animals and substantial economic losses to the farmer. It is a never-ending task that requires a rigorous approach, Bacteria, viruses and fungi will find a stronghold in these areas and finally spread disease to people, poultry, transport, vermin, insects etc. that are passing by these infectious hot spots. Virocid is an extremely concentrated disinfectant with a synergistic composition of four active ingredients. It has proven records in preventing and fighting disease outbreaks for many years: IB, IBD, avian influenza, Enterococcus, Salmonella, Aspergillus. It is amazingly effective at very low dilutions - 0.25 to 0.50 per cent - against all microorganisms: bacteria, viruses, fungi and spores. Virocid is hospital-graded according to the EPA registration in the US. Moreover, Virocid has a long residual action and can be applied in a versatile way (spraying, (hot) fogging, foaming) on surfaces, boot, dips, vehicles and equipment. virocid used in various ways such as horticulture,hospital,food processing unit,animal healthcare and personal hygiene

AVIAN INFLUENZA PREPAREDNESS.

Avian influenza has been reported in japan,Canada,Taiwan e.t.c. The necessary bio security measures are in place,surveillance control are also on going. Bio security and surveillance is the only way to stop the virus.The next line of action for countries not yet affected is to be proactive and beef up surveillance,monitoring at points of entry ,at poultry farms ,markets and airports.The same way the Ebola virus infection was monitored and controlled the AVIAN INFLUENZA VIRUS SHOULD ALSO BE TACKLED. The infection control preparedness measures set in motion has prevented avian infection in Hong Kong. The proactive prevention plan implemented widely in Hong kong healthcare system was a significant factor preventing the spread of influenza strain A H7N9 =BIRD FLU.(Jan 2015 issue of infection control and hospital epidemiology.) The infection control implemented an integrated approach utilizing active and enhanced surveillance,early airborne infection isolation,rapid molecular diagnostic testing and extensive tracing for health workers with unprotected exposure.The enhanced surveillance methods appeared to be an important key to detection of H7N9. With the above course of action and outcome,all hands must be on deck to stop the bird flu virus. BE PROACTIVE =BIO SECURITY +SURVEILLANCE= STOP THE AVIAN INFLUENZA VIRUS.

BIRD FLU.

AVIAN INFLUENZA; BIRD FLU. The highly pathogenic influenza virus is rearing its head in certain countries around the world and ravaging the poultry industry, Avian influenza virus affects birds such as chickens,turkeys, pheasants,water ducks,parrots,partridges,emus,quails and ostriches,although the susceptibility to virus varies as some birds show more fulminating signs(chickens) and others sub clinical signs(water ducks). The virus can survive outside the host for a considerable time. The route of the infection has been linked to migratory birds which harbor the virus with no clinical signs, their droppings contaminated pond of the water fowls, these pick the virus and their contact with other birds enhance the spread . The mode of spread: is from bird to bird by contact with secretions,dropping and contaminated bedding. Vehicles,equipment and tools also facilitate spread.Personnel moving between farms,abattoirs and poultry markets also facilitate spread,hence BIO SECURITY measures must be adhered to strictly on farms. The avian influenza virus strikes resulting in sudden increased mortality, however these are signs of BIRD FLU. 1) Ruffled feathers. 2)soft shelled eggs, 3)depression and drowsiness. 4)loss of appetite. 5)bluish combs. 6)green diarrhoea. 7)in coordination/paralysis. 8)hemorrhaging on feet and shank. 9}blood tinged discharge from nostrils. 10)respiratory difficulties. 11) edema of comb,wattles and eye lids. The above signs many poultry farmers can relate to because some other conditions also exhibit some of the signs,these leads them to vaccination, treatment after culling some birds.This is where the problem lies, the first step should be for you to take log of activities for the last 2 weeks; what came in?, what activities were out?,who came in?,which standard operations procedure did you or did you not perform?.while you take log of your activities, restrict movement to your farm, dispose dead birds promptly, give your birds vitamins in water and call your vet.

BIRD FLU.

Washington,Oregon activate bird flu alert. 30 countries restricts US poultry. In Germany, a white stork tested positive to H5N8,the stock and 8 other birds in the ROSTOCK ZOO. Three human cases of H7N9 in ZHAOQING. All border control points have implemented health surveillance measures. 2 people diagnosed with bird flu in egypt as @ 6/1/2015,the human cases upticks in Egypt. Bio security measures up scaled in farms,markets and control points.Airport surveillance also in place,passengers coming into country from AI zones are using masks and are monitored. Citizens are advised about safety measures such as; avoiding crowded zones.Covering mouth when sneezing and coughing.washing and cleaning surfaces with disinfectants, washing hands constantly especially after handling poultry products.
