Feedstuff capable of increasing sow production performance in large-scale pig farm and feeding method thereof

Abstract

The invention relates to a feed which can improve the large-scale hogpen sow production performance, and a breeding method; the feed comprises the following components based on weight proportions: 35-45 portions of corn, 5-10 portions of wheat bran, 5-10 portions of soybean meal, 5-15 portions of miscellaneous meal, 15-20 portions of fermented protein, as well as 10-15 portions of functional combined fibers. Aiming at the nutritional needs of sows at different stages, the invention prepares rational daily diet and uses the rich feedstuff to prepare the daily diet, as well as makes use of the fermented products in the food industry and the functional combined fibers to greatly meet the nutrient type and quality needs of the sows to improve the intestinal health of the sows, reduce the constipation problem of sows during pregnancy and improve the survival rate of embryos and litter size. The invention makes full use of fermented protein, lysine and other special nutritional factors to balance the daily dietary amino acid so as to meet the needs on micro-nutrients of the sows and promote the development of the fetus.

Description

technical field [0001] The invention relates to a feed for pigs, in particular to a feed that can improve the production performance of sows in large-scale pig farms, and also relates to a feeding method that can improve the production performance of sows in large-scale pig farms. Background technique [0002] Sow feeding is one of the important links in pig production, and the nutritional status of sows seriously affects the reproductive performance of sows and the production performance of piglets. In the past 20 years, the production performance of sows has been greatly improved. The number of litters of sows in modern large-scale farming has increased, and the amount of lactation has increased. The average litter size has increased by 9%, and the number of weaned piglets has increased by 14 %. At the same time, in order to give full play to the production performance of high-yielding sows, strict feeding and management conditions are required. At each stage of the repro...

[0005] (2) Measures and defects adopted in large-scale production

The consequence of this is that the types of nutrients in the feed are too few, and the micronutrients are too low, which cannot accurately meet the types of nutrients required by the sows, resulting in the lack of nutrients during pregnancy, which is not conducive to the intestinal health of the sows, resulting in pregnancy loss. Severe constipation in sows, insufficient intake of micronutrients, thereby reducing the embryonic survival rate of sows, seriously reducing the lifespan of sows, and in terms of production, the production performance of sows is reduced and the cost of feeding is increased
