METHOD OF BREEDING WORK WITH CORRELATING EXTERIOR TRAITS IN COWS

摘要

The invention relates to animal husbandry, in particular to milk and meat cattle rearing. A method of breeding work with correlative exterior traits includes selecting the cows taking in consideration separate correlated indices, taking additional measurements and, in a correlative series, introducing the traits, on the basis of which the critical and observed values of an correlation coefficient error in animals of various genotypes are graphically and mathematically determined and on the basis thereof carried out is selecting with the most significant correlated desirable parametersas follows: a withers height, a chest circumference, an abdominal circumference for heard reproduction and the further breeding work.
