When a dry cow transitions to being a lactating cow, her energy requirements are similar to that
of a human running two marathons a day. Because of this, the transition period from calving
to lactating is critical due to the physiological and endocrinal challenges to homeostasis these
cows face. The sudden demand in milk production can cause significant metabolic stress that
must be managed and the cow must be prepared.
By HEATHER TUCKER* *Dr. Heather Tucker is a research scientist, ruminant nutrition, with Novus International. INFERTILITY and lameness are critical challenges that dairy producers and veterinarians must deal with on a daily basis. Both issues can result in serious economic losses for producers due to decreased milk yield, reduced fertility and increased treatment costs and culling rates.
A dairy cow’s gut has a big job to do, and there are lots of moving parts. When thinking about the gut, the focus has typically been on nutrient digestion and adsorption. However, the gut plays other critical roles related to the communication it facilitates between microbes inhabiting the gastrointestinal tract and the regulation of foreign compounds trying to cross the gut barrier.
Vitamins A, D and E are essential nutrients that support a
wide range of functions in the body. As fat-soluble vitamins,
they are also subject to degradation from oxidative damage
in the feed and digestive tract. Feeding AGRADO® Plus at
recommended rates helps neutralize pro-oxidants in the diet,
in particular oxidized fat, preserving vitamins for absorption
and delivery to target tissues in the body.
Higher milk fat and milk protein levels can mean improved profits for producers.
Keeping cows free of mastitis improves overall animal health and milk quality.
Keeping high level producing cows in the herd longer returns profit to the producer.
