Short communication: Kelp taste preferences by dairy calves

Ionophore taste preferences of dairy heifers.

Two taste preference studies were conducted using six Holstein heifers in each experiment to determine preferences for no ionophore, lasalocid, or monensin in the diet. In Exp. 1, individually penned (approx. 5 mo old; 220 +/- 14 kg BW) heifers were fed a basal total mixed ration containing 46% corn silage, 46% grass haylage, and 8% soybean meal (DM basis). There were five treatments (mg/kg BW(...

Colostrum management for dairy calves.

Colostrum management is the single most important management factor in determining calf health and survival. Unfortunately, a significant proportion of North American dairy calves suffer from failure of passive transfer of antibodies from colostrum, contributing to excessively high preweaning mortality rates and other short- and long-term losses associated with animal health, welfare, and produ...

Utilization of corn silage carotene by dairy calves.

p ERRY et al. (1957)and Neumann (1960) reported that steers fed an all-concentrate ration developed vitamin A deficiency even though carotene was present in the diet in excess of requirements (N.R.C., 1958). Jordan et al. (1963) found similar results when steers were fed principally on corn silage. Steers fed a "high" nitrate silage were depleted of their liver vitamin A reserves more rapidly t...
