This is especially important in cases where a calf is pulled to assist the mother. When the cow stands, the uterus normally drops back into the abdominal cavity, which straightens out the uterine horns. [5]
This dry period is a critical part of their lactation cycle and is important for the cows health, the newborn calf and future milk production, as it allows the cow time to rest, eat and prepare for birth. During this time, the cow will produce colostrum for the newly born calf. Research has shown that this period impacts overall milk production ...
Feeding behaviors are important for the dairy cow, as feeding is how the cow ingests dry matter. However, the cow must ruminate to fully digest the feed and utilize the nutrients in the feed. [34] Dairy cows with good rumen health are likely to be more profitable than cows with poor rumen health—as a healthy rumen aids in digestion of nutrients.
Cows in California are dying at much higher rates from bird flu than in other affected states, industry and veterinary experts said, and some carcasses have been left rotting in the sun as ...
Congenital contractural arachnodactyly (CA), also known as fawn calf syndrome, is an autosomal recessive genetic disorder in cattle.
