The research was aimed at studying the efficiency of using functional feed additives based on fermented brewer's grains with vegetative filler and an adsorbent in combined feeds for broiler chickens. The use of the developed biological product resulted in increasing the live weight in the second group of chickens by 8.0 %, the average daily live weight gain – by 8.2 %, while reducing the feed used per unit of the product by 8.0 %. The results of analyzing the contents of the microflora of the caeca in the intestine showed a reduction of the common microbial number in the experimental group of chickens from 2x109 to 3x107 and an increase in the number of lactobacilli from 1x106 to 6x107. Therefore, the efficiency of the composite biological product in feeding broiler chickens has been proven.
The article presents the results of studying the effect of new bio-fertilizer on the germination and germination energy of winter vetch seeds (Vicia vilossa Roth). Experimental studies were conducted in the laboratory conditions of the Krasnodar Research Centre for Animal Husbandry and Veterinary Medicine (Krasnodar, Znamenskiy settlement). The positive effect of vetch seeds treatment with a new bio-fertilizer on germination energy and seed germination has been established. The germination energy and seed germination when treated with bio-fertilizer compared to the control (water) were higher by an average of 14.6 and 4.0%, respectively. The winter vetch variety Glinkovskaya in terms of seed germination energy turned out to be the best among other varieties. This indicator was higher by 19.35% in comparison with the control. The winter vetch variety Orlan in terms of seed germination turned out to be the best among other varieties. This indicator was higher by 9.0% in comparison with the control. This bio-fertilizer can be used to increase soil fertility and soil recultivation in plant-growing, agriculture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
