The use of sorbents in the diets of pregnant sows

Abstract

Pig breeding in Russia is one of the most important branches of animal husbandry. The share of pig breeding currently accounts for about 20 % of the total gross livestock production of the country. The profitability of this type of animal husbandry is determined by several factors, the main of which is the expenditures of feed, which is an important indicator of any agricultural enterprise engaged in the production of pork. The purpose of the work was to study the use of sorbents in the diets of pregnant sows. Scientific and economic experiment has been carried out on 3 groups of pregnant sows of Large White breed for 19 heads into each on the base of CJSC “Uralbroiler” pig complex “Rodnikovsky” in the Krasnoarmeysky district in the Chelyabinsk region. The digestibility of crude protein in the 2nd experimental group was 75,46 % the differences between the 1st control and 2nd experimental groups for this indicator were at the level of 1,41 %. The digestibility of crude fiber in sows of the 2nd experimental group exceeded of analogues of the 1st control group by 4,97 %, crude fat by 5,24 %, amounting to 41,09 (Р ≤ 0,001) and 60,47 % (Р ≤ 0,05). The feed additive glauconite in the diets of sows of the 3rd experimental group also had a positive influence on the digestibility of the main nutrients of the diet. If in the 1st control group the digestibility of dry matter was 69,23 %, in the 3rd experimental group it has increased to 72,92 % (Р ≤ 0,01) or 3,69 %, and the difference in the digestibility of organic matter was 2,08 % reaching the value of 75,51 %. The best results in the digestibility of nutrients in the diet of sows have been observed in the 2nd experimental group when using the feed additive Nabikat.
