Abstract
Relevance. The work is devoted to the results of the use of vitamin-herbal flour obtained from the green mass of onobrychis areneria on puberty cows of the holstinized blackmoth breed during pregnancy until the first phase of lactation. Experimental studies were carried out on the basis of «Krasava» in the Perm region. Vitamin-herbal flour from onobrychis areneria was grown on an experimental field of Perm NIISH. The average annual yield per cow was 6000 kg of milk. The purpose of our research was to study the effect of feeding vitamin-herbal flour from onobrychis areneria on the metabolic processes in the body of cows.
Methods. Dose and feeding period: the first and second experimental groups — from 21 days to the expected calving and up to 50 days of lactation at 1,0 kg and 2,0 kg per day, the duration of feeding was 71 days. Vitamin-herbal flour was fed individually on the feed table. The clinical condition of the animals was observed.
Results. The obtained data show positive effect of vitamin-herbal flour from onobrychis areneria on milk productivity and morphobiochemical composition of blood of experimental cows. Clinical condition of cows was without deviations from physiological norm.
