Study suggests Holstein dairy cows not harmed by producing beef crossbred calves

June 11, 2024

Facing economic challenges, dairy farmers are increasingly crossbreeding some of their Holstein cows with beef breed bulls to add value to surplus calves born in their herds. In an analysis of almost 40,000 cows, a team of Penn State researchers found that carrying and birthing the larger crossbred beef calves generally does not negatively affect dairy cow health.

Q&A: What do I need to know about avian flu?

June 7, 2024

Multiple states since March 2024 have reported dairy herds displaying symptoms caused by highly pathogenic avian influenza, raising questions about how the virus spreads, how producers can protect their animals, the risk of infection in people, and the safety of milk and meat supplies. Extension veterinarian Ernest Hovingh, clinical professor of veterinary and biomedical sciences in the College of Agricultural Sciences, answers these and other questions related to the this avian flu outbreak in dairy cattle.

Mushroom stump waste could be inexpensive, healthy chicken feed supplement

June 4, 2024

Feed costs for producing broiler chickens accounts for 60% to 70% of total production costs, and stump waste from the production of button mushrooms comprises nearly 30% of total mushroom weight. Marrying the two has the potential to reduce both cost and waste, especially in Pennsylvania, which is a national leader in the production of broiler chickens and button mushrooms. To learn whether the two are compatible, a team of Penn State researchers conducted a new study to determine how supplementing the feed of broilers with mushroom stump waste affected the growth and health of the chickens.
