Forest resources of the Krasnoyarsk region in feeding cows

An important factor in increasing the productivity of dairy cattle is to ensure the full value of diets by improving the quality of feeds and enriching its with a complex of additives from alternative sources, in particular from the richest forest resources. Scientific-economically experience by studying the effect of feeding coniferous flour on milk productivity and metabolic parameters of cows and determining its optimal dosage was carried out in the conditions of LLC Plemzavod Tayozhny Sukhobuzimsky district of the Krasnoyarsk territory. Three groups of milking cows (control and two experimental) of the Black-Motley breed of the second calving, 5 heads in each group were formed for the experiment on the principle of analogues. The duration of the experiment was 100 days. According to the scheme of studies, the control group received the main diet, the 1st experimental group in addition to the main diet received coniferous flour at a dosage of 50 g/head/day, the 2nd experimental group – coniferous flour at a dosage of 100 g/head/day. Research and data processing were carried out according to generally accepted methods. As a result of researches positive influence of coniferous flour on milk productivity and technological properties of cow milk was established. The analysis of the obtained data allowed to determine the most effective dosage of coniferous flour for the diet of cows – 50 g/head/day, which contributed to an increase in milk yield for 100 days of lactation by 15.6%, the milk fat amount – by 29.8%, the milk protein amount – by 17.1%, milk of basic fat content – by 29.4%, improvement technological properties of milk.
