Researchers are looking at the effect of antibiotic growth promoters (AGP) on intestinal microbiota in food animals, as a novel way to identify obesity-specific microbes in humans. Researchers hope to build on the more than 50 years of observation of the growth-promoting effect of AGPs on food animal production, to understand the relationship between gut microbiota and human obesity.
Alternative Protein: Assessing the Sustainability of Insect Production
A research team from the Netherlands, Germany and Switzerland studied the sustainability of old and new protein sources for animal feed. The life cycle assessment project found that insect production is a sustainable way forward for the feed and food industry.
Poultry: Understanding How Flu Strains Jump Species
A new UK study is hoping to improve understanding of how to combat influenza strains. Researchers are looking to identify genes that are important in reducing infections by influenza A virus in pigs and chickens, and genes that limit the spread of the virus to people.
Poultry: Selecting for Good Feather Cover Related to Bird Welfare
Good feathering is important for a bird's health, welfare and productivity. And a new Dutch study investigated how genomics can be used to add traits to select robust birds with feather cover for a longer period. A well feathered bird is able to regulate its body temperature, and the feathers directly protect the bird's skin.
Swine: Getting Closer to an ASF Vaccine
Chinese researchers may be closer to producing a commercially viable vaccine for African swine fever (ASF). They have isolated a strain of the ASF virus that's been spreading across China - providing the opportunity to conduct basic research and possible answers to this devastating disease.
Swine: Studying the spread of ASF
A new Kansas State University study confirms that African swine fever (ASF) can be transmitted to pigs through contaminated feed and liquid. The study is the first of its kind, and the findings support the critical need for feed biosecurity in the swine industry.
Beef: Managing Pain Control in Older Castrated Calves
An Alberta research team found that pain medication helps two-month-old calves feel better and return to normal soon after branding and/or castration. This study follows up on their previous work that showed calves castrated at one week of age show fewer signs of pain and heal faster than calves castrated at two months of age. Using cost-effective and practical methods to reduce pain and stress will also support consumer confidence in Canadian beef.
Beef: Mob Grazing Provides Sustainable Pasture Management
Intensive grazing makes efficient use of pasture and encourages wild species habitat. An Ontario couple is being recognized for their modified mob grazing - moving cattle as many as three times a day to a narrow strip of fresh pasture. When the pasture is grazed, cattle are quickly moved to another grazing area, allowing for as many as five days for a paddock to rest between grazing.
Dairy: Incomplete Milking Benefits Early Lactation
A Canadian researcher has found incomplete milking during the first five days of lactation delivers positive health outcomes for the cow. Slowing down the influx of milk production during this critical period allows the animal's metabolism time to adapt, and results in a sharp drop in metabolic and immune disruptions.
Dairy: Measuring Performance by Corn Processing Method
Researchers from Iran and Russia studied the effects of different corn processing methods and corn with different levels of protein on dairy cow performance. They compared steam-flaked corn and finely ground corn with different levels of protein. While processing and protein levels may interact to affect nutrient digestibility, it didn't impact the feeding and chewing behavior of lactating cows.
Aquaculture: Protein that is poised to feed the future
The global aquaculture industry is growing at a rate of 6% per year and poised to be a major source of protein for a growing world population. The sector has multiple opportunities for growth that will depend on collaboration throughout the industry to ensure safe and sustainable development.
