"Free-stall," untied cattle in small herds produce less milk than cows tied to their stalls but have a higher reproductive performance and suffer less teat injuries and metabolic diseases. Researchers writing in BioMed Central's open access journal Acta Veterinaria Scandinavica compared performance and health within the two stall types in response to a ban on the construction of new tie-stalls.

The mysterious "3/4 law of metabolism" is wrong. "Actually, it's 2/3," says University of Vermont mathematician Peter Dodds. His analysis from networks helps overturn almost 80 years of belief in a near-mystical relationship between the size of animals and their resting metabolism.

Switching from warm-season grasses to cool-season forages can give livestock a belly ache, in some cases a deadly one, according to Texas AgriLife Research scientists.
Dr. Bill Pinchak, Texas AgriLife Research animal nutritionist at Vernon, is leading a team of scientists who are using state-of-the-art technology -- metagenomics -- to determine how changes in diest affect microbial communities in the digestive tract of cattle and how these changes may increase risk of disease.
