Immune function differs in Marek’s resistant chickens

Photo: The Pirbright Institute. In new research that could pave the way for the development of more effective vaccines against Marek's disease, researchers with The Pirbright Institute in the U.K. have identified key immune response differences in chickens resistant to the disease. In a recent paper published in Frontiers in Immunology, the researchers showed how … Continue reading Immune function differs in Marek’s resistant chickens

Role of vitamin D in bovine TB investigated

Photo by Matthias Zomer on Pexels.com While bovine tuberculosis (bTB) has been "nearly eradicated" in the U.S., according to USDA's Animal & Plant Health Inspection Service, Europe continues to struggle with the disease, particularly in the U.K. and Ireland. Across Ireland, it is estimated that bTB-infected herds have a 30-40% chance of the disease recurring … Continue reading Role of vitamin D in bovine TB investigated

First honeybee vaccine ‘game-changer’

Researchers from the UGA Bee Lab study hives. Delaplane says that honey bee vaccines would be a game-changer for beekeepers who have had few resources beyond supportive therapies for decades. (Photo by Keith Delaplane) Vaccines are a proven benefit in the world of animal science, and soon, it may be possible to vaccinate six-legged livestock, … Continue reading First honeybee vaccine ‘game-changer’

Project hopes to solve mastitis on organic dairy farms

In organic dairy production, producers are limited on disease prevention and treatment options. Organic dairies have fewer tools in their animal health toolbox due to organic program standards, but their cows are still faced with disease conditions. Bovine mastitis is one of the most common and costly diseases in the dairy industry, and a multi-state … Continue reading Project hopes to solve mastitis on organic dairy farms

Novel imaging method to assess bone strength in hens

Photo by Rachel Vine on Pexels.com Laying hens are at risk of bone fractures due to biological changes linked with egg production. A novel method developed by The Roslin Institute in the U.K. enables poultry breeders to consider bone density in laying hen selection, which would allow greater bird health and welfare. Strong bones offer … Continue reading Novel imaging method to assess bone strength in hens

Vaccines possible for prion diseases

His original research focused bovine spongiform encephalopathy in cattle, scrapie in sheep, and chronic wasting disease … Continue reading Vaccines possible for prion diseases

Lysine linked to reproductive health in dairy cows

Photo: University of Illinois Dairy cattle are especially prone to reproductive health issues around calving, which affects fertility and conception rates in the next cycle, and a new University of Illinois study is showing that rumen-protected lysine may improve uterine health if fed during the transition period. “Right after calving, the uterus is undergoing a … Continue reading Lysine linked to reproductive health in dairy cows

Brucellosis study targets cellular function

Photo: Washington State University While brucellosis in the U.S. has been "essentially eradicated," according to Washington State University researchers, the disease — in livestock and in people — remains a significant global concern. Now, Washington State researchers have been awarded a $2.75 million grant to explore how bacterial proteins work together to cause one of … Continue reading Brucellosis study targets cellular function

IBV replication temperature sensitive, could aid vaccine development

Photo by Leonardo Jarro on Pexels.com Infectious bronchitis virus (IBV), a highly contagious coronavirus in poultry, causes respiratory symptoms and affects the reproductive tracts of birds, making it a significant economic and welfare concern for the global poultry industry, according to The Pirbright Institute in the U.K. Pirbright researchers have been investigating potential vaccines against … Continue reading IBV replication temperature sensitive, could aid vaccine development

Bioactive compounds aid calf gut development

Photo by cottonbro on Pexels.com Feeding calves transition milk instead of milk replacer in the first days of life may stimulate intestinal development and improve health scores, according to a study published by Michigan State University researchers in the Journal of Dairy Science. For the study, the researchers examined the effects of transition milk — … Continue reading Bioactive compounds aid calf gut development
