Dogs could be more similar to humans than we thought.Dog and human gut microbiomes have more similar genes and responses to diet than we previously thought, according to a new study. Dog and human gut microbiomes have more similar genes and responses to diet than we previously thought, according to a study published in the open access journal, Microbiome. Dr Luis Pedro Coelho and colleagues from the European Molecular Biology Laboratory, in collaboration with Nestlé Research, evaluated the gut microbiome of two dog breeds and found that the gene content of the dogs microbiome showed many similarities to the human gut microbiome, and was more similar to humans than the microbiome of pigs or mice.

STEPS TO ENSURE ANTIBIOTIC FREE POULTRY PRODUCTION.

Taste and health concerns has made clamor for antibiotic free production in the poultry sector a global issue,hence various methods and strategies have been employed to faze out antibiotic use.The following steps are some of the measures; Diets to promote growth and positive microflora. What a bird eats plays a large role in the success of an antibiotic-free (ABF) operation. To combat negative microflora in digestive tracts, growers need to pick feed and additives that promote the right kind of gut environment. They also need a diet that can replicate the effects of antibiotic growth promoters. A strictly vegetarian diet when switching to ABF is recommended. Growers should try and get as close to all-vegetarian diets as possible and find out the animal by-product content of the product. looking for feed with more high-quality fats and less indigestible protein is essential for antibiotic free production. Reducing the presence of bacteria in feed and water is essential as well. The issues with bacteria can be solved through good feed mill management and ensuring the feed is heated to at least 185 degrees Fahrenheit to kill bacteria. Keeping a clean water supply prevents the spread of disease and is essential because birds drink twice as much as they eat. Antibiotic alternatives There’s a variety of feed additives being marketed as alternatives for growth-promoting antibiotics such as organic acids, phytogenics, probiotics, prebiotics and short-chain and medium-chain fatty acids. These products look at one major goal: establishing a healthy gut microflora and preventing the growth of harmful microbes. Using a combination of probiotics and prebiotics has shown promises in doing exactly that, but they are not a silver bullet. The use of a combination of probiotics, prebiotics and other feed additives will help promote a healthy gut in broiler flocks. The importance of starting a feeding program that will promote healthy gut in chicks and pullets as soon as possible cannot be overemphasized. Getting the right microbes in place early can prevent unwanted bacteria and other microbes taking up residence inside the gut.

FERMENTED FEEDING IN PIGS FOR INTESTINAL HEALTH.

Liquid feed is a great way to ferment protein-rich, home-grown fodder such as rape seed oil meal, peas and field beans or recycle liquid co-products from the human food industry into pig feed. Liquid feed for pigs comes into two varieties. Non-fermented and fermented. Non-fermented is mainly used and is simply a matter of mixing the cereals or complete feed with water and minerals. It takes around 2-4 minutes of mixing time (sometimes up to an hour). The fermented version takes much longer to prepare, a few hours to 6-12 hours on average. The latter is of particular interest as it is known for its positive effect on intestinal health and Salmonella control. Especially in line with the pressure on using antibiotics to treat digestive disorders in pigs and the tight margins in the pig industry, fermented liquid feed is gaining interest. Denmark has been a large user of fermented feed, mainly to control Salmonella as part of their strict national control plan for Salmonella reduction in the Danish food chain. However, the use of fermented feed is not the way to go for all pig farms, It really depends on the type of farm and whether critical points can be met to make this type of feeding a successful one. Since the announcement of the ban on the use of antibiotics as antimicrobial growth promoters in the feed of pigs in 2006 the investigation towards alternative feed additives has augmented considerably. Although fermented liquid feed is not an additive, but a feeding strategy, the benefits cannot be undermined.

MANAGING COCCIDIOSIS..

The critical control points for coccidiosis vaccination; effective way of preventing coccidiosis is vaccination at the hatchery. This only works out well if critical points are taken into account, both at the hatchery as well as in a later stage at the farm. Vaccination against coccidiosis in poultry is used mainly in broiler, turkey and layer breeder flocks; commercial layer flocks reared on the floor; antibiotic free broiler operations and some commercial turkey grower operations. Vaccinating with a coccidiosis vaccine in conventional broiler operations is increasing rapidly, mainly in a rotational programme with anticoccidials, aiming at restoring the sensitivity of the anticoccidials. Whatever the reason for vaccinating with a coccidiosis vaccine, attention to some critical factors will determine the level of success of establishing immunity against coccidiosis. The Eimeria parasites given during the vaccination, infects the intestinal cells and continues its life cycle inside the gut. Un sporulated oocysts are excreted after 5-7 days, time depending on the species; the oocysts then sporulate outside the bird, given suitable environmental conditions exists, and after re-ingestion of these sporulated oocysts, infection and another cycle starts. Immunity development is dependent on successful excretion of oocysts and then re-ingestion of these sporulated, shed oocysts. Depending on the species, 2-3 infection – excretion – re-ingestion – re-infection – excretion cycles are needed to acquire a protective immunity. The vaccination process and the subsequent development of immunity, irrespective of the application method, can thus be divided in two distinct areas:Vaccine application – ensuring uptake of the vaccine . Post vaccination management include ; ensuring suitable environmental conditions for sporulation exists and recycling of the sporulated oocysts takes place. The necessary procedures to actually check the vaccine uptake by the birds must be implemented. Adding a suitable dye to the vaccine makes this possible by randomly checking boxes/crates of chicks/poults and see if they actually did ingest the vaccine by counting the number of chicks/poults in the box/crate with a dye colored tongue . . Recycling of oocysts and monitoring Oocyst shedding can be measured by sending faecal samples to a lab that is capable of doing an Oocyst Per Gram (OPG) count. Faecal material (NOT bedding) is collected at specific intervals post vaccination: Chickens at days 7/14/21/28 post vaccination Turkeys at days 6/13/20/27 post vaccination. The first count should be positive. This is a very good indicator of the effectiveness of the vaccine application done in the hatchery as well as an indicator that the vaccine that was used was still infective. The second count should show a significant increase. This is used as an indicator that the shed oocysts sporulated and re-ingestion of these shed oocysts have taken place. Read more ;world poultry.
