ABSTRACT
Six pairs of newborn calves were used in a 60-day trial to study the effects of a mixture of colostrum and skimmilk containing 20% solids. The high-solids group gained an average of 70 lb. as compared to 54 lb. for controls which received skimmilk containing 13% solids. Calves in the high-solids group consumed a total of 171 lb. of concentrate feed as compared to 353 lb. eaten by the controls. These differences are significant at P = 0.01.
The high-solids calves gained an average of 4.2 in. in height at withers and controls gained an average of 3.8 in. The high-solids calves consumed a total of 94.4 lb. hay and the controls consumed 63.0 lb. No scouring was observed in controls, and two calf-days of abnormal feces were observed in the high-solids group.
