ABSTRACT
Three milk replacers compared contained per cent of dried whey, dried skimmilk, a soy protein concentrate (Promosoy, Central Soya Co.), and lard oil, respectively, as follows: A-76.6, 0, 12.2, 10; B-67.9, 14.9, 6.0, 10; and C-59.2, 29.6, 0, 10. The three replacers were equal in supplemental vitamins, minerals, antibiotic, and contained approximately 18.5% protein. They were fed to calves for 35 days. Average gains (kg) and fecal scores, scale of 0 (normal) to 3 (fluid), of calves on Replacers A, B, C were: 13.0, 17.8, 16.2 and 0.69, 0.60, 0.97. Blood serum protein, hemoglobin, and packed cell volumes of these groups were similar.
