RU2012148459A - METHOD FOR ASSESSING MILK QUALITY IN COWS - Google Patents

Abstract

A method for evaluating the quality of milk in cows, including evaluating milk according to a set of quality indicators, determining the quality of milk, characterized in that pre-determined indicators of milk protein yield - MDB, mass fraction of fat - MF and the number of somatic cells - KSK in milk, then determine the yield of milk protein in a single milk yield of two or three months of lactation of a cow according to the formula: where Y is a one-time milk yield, kg; MDB is the mass fraction of protein in cow's milk,%, then the highest value of milk protein yield among cows is determined - SBS, kg, then the milk protein yield indicator is determined from the expression: where SBS is the highest value of milk protein yield among cows, kg, then the yield is determined milk fat from the expression: where MJ is the mass fraction of fat in milk,%, then determine the highest yield of milk fat among the cows of the study group, kg, determine the yield of milk fat by the following formula: where HUM is the highest value the course of milk fat among animals, kg, then determine the indicator of the number of somatic cells in milk - PSCC according to the formula: where KSK - the number of somatic cells in cow's milk, thousand / ml, the quality of milk in a cow is determined by the indicator of milk quality in a cow, by the formula : where K is the number of estimated indicators.

A method for evaluating the quality of milk in cows, including evaluating milk according to a set of quality indicators, determining the quality of milk, characterized in that pre-determined indicators of milk protein yield - MDB, mass fraction of fat - MF and the number of somatic cells - KSK in milk, then determine the yield of milk protein in a single milk yield of two or three months of lactation of a cow according to the formula: $$\mathrm{AT}MB=\frac{\mathrm{At}\cdot MDB}{\mathrm{one\; hundred}},\text{(one)}$$

where Y is a one-time milk yield, kg; MDB - mass fraction of protein in cow's milk,%, then determine the highest value of the yield of milk protein among cows - SBS, kg, further determine the indicator of the exit of milk protein from the expression: $$P\mathrm{AT}MB=\frac{\mathrm{AT}MB}{N\mathrm{AT}MB},\text{(2)}$$

where SBS - the highest value of the yield of milk protein among cows, kg, then determine the yield of milk fat from the expression: $$\mathrm{AT}MF=\frac{\mathrm{At}\cdot MDF}{\mathrm{one\; hundred}},\text{(3)}$$

where MJ - mass fraction of fat in milk,%, further determine the highest yield of milk fat among the cows of the study group, kg, determine the yield of milk fat according to the following formula: $$P\mathrm{AT}MF=\frac{\mathrm{AT}MF}{N\mathrm{AT}MF},\text{(four)}$$

where HUM is the largest value of the yield of milk fat among animals, kg, then determine the indicator of the number of somatic cells in milk - SCKS according to the formula: $$P\mathrm{TO}\mathrm{FROM}\mathrm{TO}=\frac{900-\mathrm{TO}\mathrm{FROM}\mathrm{TO}}{900}\text{(5)}$$

where KSK is the number of somatic cells in cow's milk, thousand / ml, the quality of milk in a cow is determined by the indicator of milk quality in a cow, by the formula: $$P\mathrm{TO}M=\frac{\mathrm{one}}{\mathrm{TO}}\left(\frac{\mathrm{AT}MB}{N\mathrm{AT}MB}+\frac{\mathrm{AT}MF}{N\mathrm{AT}MF}+\frac{900-\mathrm{TO}\mathrm{FROM}\mathrm{TO}}{900}\right)\text{(6)}$$

where K is the number of estimated indicators.
