A study evaluating 2,238 Canadian beef calves found that trailer microclimate significantly impacts calf welfare during transport. Calves experienced more shrink in summer months and higher salivary cortisol levels in winter, but overall arrived healthy.
A study published in the Journal of Animal Science found that wheat can be used as an alternative energy source for beef cattle, with optimal feeding levels determined to be above 50%, and increasing monensin supplementation improving feed efficiency, while proper grain processing is necessary.
Researchers found that using grocery byproduct as a supplemental feed source in total mixed rations improves dry matter intake and apparent digestibility, leading to increased animal performance. The study also developed a pricing method for the feed based on its nutrient content and market prices.
A new scientific review of genetically engineered feeds in livestock diets concludes that feeding these crops has no impact on the health or productivity of animals. The review examines nearly 30 years worth of data from over 100 billion animals, revealing comparable performance and health between GE-fed and non-GE-fed animals.
A new study by the American Society of Animal Science found that adult horses with low selenium levels have suppressed cell-mediated immunity, while antibody production remained unaffected. The researchers aimed to understand how different levels of selenium affect the immune system in horses.
A study by Purdue University researchers found that pigs thrive on lipids from soybean oil, leading to improved growth performance. The study's results suggest that using concentrated energy sources like soybean oil can help counteract issues limiting growth in nursery pigs.
Researchers found that pregnant sows housed on rubber slat mats had a reduced risk of swelling and wounds on the limbs, but an increased risk of sole and heel lesions. The study suggests that rubber slat mats could improve animal well-being by reducing locomotory problems in swine.
Researchers used biotechnologies to increase food production while lowering harmful gas emissions from cattle. The study found that biotechnology treatments improved milk production and reduced greenhouse gas emissions.
A new study suggests that performance in foundational biology courses is a strong predictor of performance in high-level animal science courses. Students who take genetics as sophomores and juniors tend to perform well, while those who wait too long may struggle with advanced courses.
Research suggests producers feeding high levels of DDGS reduce fat softening by limiting feed in last weeks before harvest. Pigs fed diets with saturated fats did not show firmer belly flop distances, contradicting long-held assumption that they improve fat quality.
Researchers found that chickens with larger digestive organs eat less feed and produce less waste, potentially saving farmers up to 9.76 tons of feed per hatch. Selecting for this trait could also help identify the genes controlling digestive efficiency in chickens.
Researchers at the Lactation Biology Symposium discovered that drinking milk at an early age can change how certain genes are expressed. This epigenetic effect can have long-term implications for behavior and cell development in offspring.
In a new study, researchers found that young pigs prefer a diet rich in soybean meal, with a clear preference for this ingredient over other meal options. Replacing soybean meal with canola meals could lead to cost savings in pork production, but glucosinolates may impact feed quality.
Researchers found that as cows' core body temperatures rise above 101°F, they stand for longer periods to disperse heat. Dairy producers can use this behavior to improve herd well-being and efficiency by providing cooling systems.
Research presented at the American Society of Animal Science meeting found that moderate exercise during gestation can positively affect ovarian cell development. The study showed increased cell proliferation in ovaries from fetuses born to exercising mothers, suggesting potential benefits for future fertility.
Researchers have developed a new line of transgenic 'Enviropigs' that can digest high levels of phosphorus in plant matter, eliminating the need for supplements. This breakthrough could improve food production and reduce environmental pollution by producing less phosphorus waste.
A line of special liver cells called PICM-19 has the potential to perform many of the same functions as a human liver. The immortal cell line can be used to study various diseases, including liver cancers and cystic fibrosis, and may enable the development of artificial liver devices.
Researchers found that raw meat diets met many nutrient requirements for cats, but there were gaps in linoleic acid and arachidonic acid levels. Pet owners may need to supplement with other nutrients, including fat and essential fatty acids. The study highlights the importance of proper nutrition for domestic and exotic felines.
A new study estimates that the cow-calf phase produces the greatest greenhouse gas emissions during beef production, with methane emissions from a roughage diet. This finding highlights the importance of managing cattle feed and nutrition to reduce carbon footprint.
Researchers found that a small dose of ractopamine increased muscle mass and feed efficiency in pigs without compromising meat quality. The study confirmed previous findings that 5 mg/kg is an appropriate dose for Brazilian commercial pork production.
A bacterial supplement containing lipid-producing Rhodococcus opacus increased circulating triglycerides in weanling pigs, providing an alternative source of energy. This could help strengthen the immune system and fight off infections more efficiently during a critical stage of development.
