Concentrated extruded feed application in feeding marals

The purpose of reseaech is to study the use of concentrated extruded feed in the feeding of marals. Tasks: to study the feeding rations of marals; to study the dynamics of growth and maturation of antlers; to determine the economic efficiency of the use of concentrated extruded feed in the feeding of marals. Scientific and practical research was carried out in the Mana District of the Krasnoyarsk Region. Two groups of marals were formed, 5 heads each. in each. In the control group, the animals were fed the main diet, consisting of meadow hay, cereal-bean haylage and a grain mixture of wheat (30 %) and oat mash (70 %), in the experimental group, extruded concentrated wheat feed (49 %) was used instead of mash. oats (49 %) and chalk (2 %). In the experimental group, the animals' appetite improved on the 8th day, the feed intake increased by 8 %. In the experimental group, compared to the control group, the velvet antlers ripened 29 days earlier; the weight of the antlers was higher by 980 g; the girth of the right horn is 1.3 cm larger, that of the left horn is 1.2 cm larger. In the control group, per 1 head, the total cost is lower than in the experimental group by 35.36 %. The cost of 1 kg of antlers in the experimental group is lower by 427.45 rubles. (13.2 %), and the level of profitability is higher by 18.5 % than in the control - 40.1 %. It is recommended to use extruded concentrated feed in the amount of 1.3-1.8 kg/head in feeding deer per day.
