Effeciency of new age of variability-whole alternatives to whole milk replacers for growing calves

Abstract

Implementation of developed base concentrates to the composition of new types of milk replacers ensures enough high parameters of their nutrition value. Offered types of replacers surpassed base types not only on quality of fat, but also on the level of fat: 12,5-12,6 % on the average, against 11-12 % in base types of replacers. The ratings of safety of developed types of replacers did not exceed extreme concentration. Price decrease (on the average by 23,2 %) of new types of substitutes along with appreciable increase (on the average by 13,2 %) of calves weight gain at their feeding, significant total economic benefit was provided. Cost of obtained gains on 1 rouble of expenditures to new types of milk replacers increased on the average 1,48 times or by 47,5 %, as compared with actually used replacers.
