Research from the University of Florida shows that calves exposed to heat stress before birth have lower birth weights and compromised immunity.
Two real world examples of group housing and feeding systems for calves and a discussion of the challenges in each system.
Dairy producers are encouraged to design a parasite control program with their veterinarian. This article presents some elements that might be considered in crafting a more effective program.
Crows are not dumb birds.
A decrease in milk butterfat sends the alarm but is the diet to blame?
There are several ways to economically evaluate better reproduction. Whatever economic indicator is used, research suggests that the more efficient our dairy producers become at getting their entire dairy herd pregnant, both first service cows and repeat breeders, the potential exists for increased profitability for the dairy enterprise.
Insight into world supply and demand factors that influence milk price.
Penn State research suggests that when low quality forage is added to the diet to achieve extra chewing or rumination, chopping it fine enough to minimize sorting will help cows to consume the amount of forage desired and still provide physically effective fiber.
Transitioning cows from the dry period into and through early lactation has a huge effect on the overall production and health of the entire herd. The way we house and manage the dry and prefresh cow ultimately determines the level of production she can achieve.
Haylage shrink of 22% keeps the PSU Dairy on their toes but setting goals and making a plan of action keeps milk production going strong.
Penn State Extension Dairy Team has scheduled two workshops to help increase milk quality through collecting and indentifying on-farm cultures.
Workshops designed for English-speaking milkers and managers will emphasize proper milking techniques and standard operating procedures.

New corn silage and candy product pose challenges to ration balancing.
It’s that time of year again! Cold weather is approaching and keeping every newborn and young calf healthy might be challenging. Wind and snow can add stress to even the healthiest of calves.
Penn State research has determined that histidine can be a limiting amino acid in high-producing dairy cows fed corn silage and alfalfa haylage-based diets deficient in metabolizable protein (MP). This is primarily a result of the relatively low histidine concentration in microbial protein synthesized in the rumen. When formulating diets for high-producing dairy cows fed MP at or below NRC (2001) requirements, nutritionists should also balance for digestible histidine supply.
