Article:In the search for more sustainable and cost-effective feeding options, dairy farmers may soon have a new alternative to soybean meal when feeding young calves. A recent study published in the Journal of Dairy Science explored whether a high-protein...
A recent study published in the Journal of Dairy Science looked at how feeding whole cottonseed (WCS) affects milk production, milk fat, and methane emissions in dairy cows. Whole cottonseed is commonly used in dairy diets because it provides...
In people and many animals, how the body handles sugar (glucose) and the hormone insulin changes throughout the day thanks to something called circadian rhythms—our internal 24-hour clocks. Until now, scientists didn’t know if dairy cows had the same...
Dairy cows are significant contributors to methane emissions, a potent greenhouse gas. Researchers have been exploring various strategies to mitigate these emissions, including dietary supplements like 3-nitrooxypropanol (3-NOP). A recent study published in the Journal of Dairy Science examined...
A recent study shows that extreme heat is already taking a toll on dairy farms in the Midwest and Eastern U.S., and the problem is expected to get worse by 2050. The research found that:
Small farms and high-producing...
Introduction
Artificial insemination (AI) is widely used in the global cattle industry to enhance genetic potential and streamline breeding. However, AI also carries the risk of introducing bacterial pathogens to herds. To mitigate this, antibiotics are added to semen extenders...

ABSTRACT
Twin births in dairy cattle is generally unfavorably associated with reproductive performance and calf survival in dairy cows. Genetic selection to reduce twinning rate in dairy cattle may be desirable, provided no undesirable correlated responses...
Nitrogen use efficiency (NUE) is a growing focus in dairy farming, as it directly impacts environmental sustainability, farm economics, and overall herd health. This study analyzed 278 Holstein-Friesian grazing dairy cows, evaluating how their NUE (nitrogen used and stored...

Abstract
Sole ulcers, a common cause of lameness is the costliest non-infectious foot lesion in dairy cows and one of the most prevalent non-infectious foot lesions in freestall housing systems. Costs associated with sole ulcers are treatment costs, plus...
