Young marals (yearlings) fodder yeast feeding influence on their antel productivity

The purpose of research is to study the effect of feeding fodder yeast to young deer (yearlings) during the formation of antlers on their productivity. Objectives: to study the effect of feeding fodder yeast to marals on blood morphological parameters; calculation of the palatability of fodder yeast in the diet of first-timers; determination of their antler productivity after 30 days of fodder yeast feeding. The test object was 2-year-old deer (yearlings). The subject of research is the diet, the palatability of the feed additive, blood and blood serum, grading data. The experimental part of the work was carried out at the Abinsk maral farm Experiment Station Novotalitskoe of Federal State Budget-Funded Scientific Institution “Federal Altai Scientific Centre for Agrobiotechnologies” (FGBNU FANTsA). For the experiment on feeding fodder yeast, young deer at the age of 21 months were divided into two groups. Animals of the control group received the basic ration (RR), consisting of standard feeds used in deer breeding: hay, oats, grain haylage. For aimals from the experimental group the part of the oats was replaced by fodder yeast. In the course of research, it was determined that in young marals, hematological blood parameters, the content of the total amount of protein and its fractions did not go beyond the physiological norm. The superiority in some indicators in animals of the experimental group was: hemoglobin - by 4.5 %, color index by 6.0%, and the advantage was also noted for α-globulins. The palatability was 87.0 %. The antler productivity of the antlers of the experimental group is more by 100 g than that of the animals of the control group, due to the superiority of the length of the trunk and processes of the antlers by 1-2 cm.
