Manipulation of the metabolic and energy state
by means of nutrition to minimize body condition loss and to reduce the
extent and duration of negative energy balance during the early postpartum
period should improve the reproductive efficiency of dairy cattle. One
nutritional option is to maximize the energy density of the diet by fat
supplementation. Inclusions of unsaturated ruminal inert fat (calcium
salts of fatty acid) in ration will increase energy intake during the
early postpartum period. Researchers (Dr. McGuire and co-workers) in the
Department of Animal and Veterinary Science have shown that supplemental
calcium salts of conjugated linoleic acid (CLA) increased milk yield,
body condition score and body weight while improving net energy balance.
Interestingly, CLA supplementation did not exert a negative effect on
dry matter and energy intake, which is typical of fat supplemented diets.
