Abstract

It was showed that the investigated factors "the feeding level" and "the level of concentrates in the ration" as independent, affect the protein content in milk at the level of q2=3.7%, 2.3%, and the yield of milk protein-q2=12.3%; 10.2% accordingly. These factors, also, have almost the same influence on studied indices not only as a separate factor, but also in combination with other factors. The other side, if we consider these factors as independent, they have an influence on the protein content in milk 3 times (cattle feeding) and 4 times (the level of concentrates) less than on the yield of milk protein. During the analysis of the inflence of the feeding level together with other studied genetic and non-genetic factors the most influential pairs of factors in both variants were "father-cattle feeding" pair. Also, the feeding level together with genetic factors like "breed combination" and "mother's productivity" had a large degree of influence. Thus, factor "the level of concentrates in the ration" conjointly with the factor "father" affects protein content in 1.2% more than "the feeding level" factor. A similar tendency is observed at factors "breed combination" and "mother's productivity", where the difference makes 0.7% and 0.1% accordingly. Regarding the yield of milk protein, according to the results of the studies, factors "the feeding level" and "the level of concentrates in the ration" independently affect the index mentioned above 3-4 times more than in pairs with other genetic and feed factors with a high degree of defined confidence. The pair of "calving month-the level of concentrates in the ration" turned out to be doubtful and with a very small level of influence. All the other pairs of factors have a definite influence on both the protein content and its quantity.
