The Use of Yeast in Calf Meals and Pellets1
Paul E. Newman and
E. S. Savage
Cornell University, Ithaca, N. Y.
ABSTRACT
Sixty-five calves were used in studying different calf starter formulas. The following conclusions seem to be warranted:
- The dry calf starter method in these studies consistently produced calves above normal in weight and of desirable body and skeletal development.
- The use of dried brewers' yeast and cereal yeast feed in the dry calf starter formulas resulted in greater growth and body development.
- The total digestible nutrient requirement per unit gain in weight was lower for the yeast-containing calf starters than for the others.
- The previous level of 20 per cent dried skimmilk can be reduced to 10 per cent without decreasing the effectiveness of the calf starter when yeast or a combination of yeast and soybean oil meal is used to keep the protein level the same.
- Using a level of 30 per cent dried skimmilk lowered the palatability of the starter and resulted in slower growth.
- Pelleting of the two formulas studied decreased the consumption of the calf starter by young calves and resulted in slightly slower growth.
