THE PRODUCTIVITY OF WINTER WHEAT OF THE VOLZHSKAYA K VARIETY WHEN SOWING FRESHLY HARVESTED SEEDS AND A ROLLING STOCK
One of the main ways to increase productivity in animal husbandrfyis to improve methods of breeding. Breed selection - the most effective method of improving the existing and creating the new, more valuable breeds, types and lines of animals. At the same time, this is one of the most difﬁcult and important issues in breeding work. The object of investigation was a herd of a breed reproducer: SPK - collective farm "Avangard" of the Uvinsky district, the Udmurt Republic; the studies were carried out by means of the analysis of the primary data of pedigree and zootechnical accounting, based on pedigree animals on pedigree cows of the form 2-MOL, data of zootechnical and pedigree records. On the results of researches made it is necessary to note, that the selection of bulls-manufacturers of the V.B. Idyl has proved to be the most successful for the cows of S.T. Rokyt line; the productivity of cows obtained from this selection was 8012.0 kg - 3.49% - 3.16%. Also, the most successful combinations for milking are the selection of bulls of M. Chiftein line for the VB Aidial and M. Chiftein lines, 7454.2 kg and 7588.3 kg respectively, and the R.Sovering line for the M. Chiftein and R. Sovering cows' lines - 7539.5 kg and 7432.1 kg, respectively. Analyzing the dairy productivity of cows obtained after related mating, we note that in general, inbreeding did not have a negative effect on milk production, thus in most cases over 6000 kg of milk were received from inbred cows, with a mass fraction of fat from 3.35 to 3.52 %. The best results were obtained with remote inbreeding at the ancestor of Ganoverhil Starbuck 352790 in grades V-IV, V-V - 7247.4 kg of milk with a fat mass fraction of 4.50%.
