METHOD FOR EVALUATION OF QUALITY OF MILK COWS

摘要

A method of evaluating the quality of milk cows, including an assessment of milk by the complex quality parameters, determining milk quality characterized in that the pre-determined parameters output milk protein - BMD, mass fraction of fat - SEM and the number of somatic cells - XK in milk, it is further determined yield of milk protein milk yield in the single two or three months of lactation cows by the formula: where Y - yield of a one-off, kg; BMD - mass fraction of protein in the milk of cows,%, then determine the largest value of the output of milk protein include cows - NNB kg, more determined index output dairy protein from the expression: where NNB - the maximum value of the milk protein yield among cows kg, more determined yield milk fat from the expression: where MWA - mass fraction of fat in milk,%, then determined largest value among the output of milk fat cows studied group kg determine output rate of milk fat according to the following formula: wherein NVMZH - largest value you stroke milk fat in animals kg, more determined measure of the number of somatic cells in milk - PHSC by the formula. where CSC - the number of somatic cells in milk cows thousand / ml, the quality of milk from the cow is determined in terms of the quality of milk from a cow, according to the formula : where K - the number of performance indicators.
