Embodiment 1

[0021] Embodiment 1: On the basis of complete feed, 20-100 grams of chitosan oligosaccharides are added per ton of feed. Feed the sows 21 days after mating in estrus, and limit food intake during pregnancy according to the principle of weight control. Feed was given ad libitum during lactation until piglets were weaned on day 21.

Embodiment 2

[0022] Example 2 On the basis of the full-price feed, 200-1000 g of fructooligosaccharides were added per ton of feed. Feeding method is with embodiment 1.

Embodiment 3

[0023] Example 3 On the basis of complete feed, 20-100 grams of chitosan oligosaccharide, 200-1000 grams of fructo-oligosaccharide and 500-2000 grams of zymosan were added per ton of feed. Feeding method is with embodiment 1.

Abstract

The invention relates to a functional glycoconjugate (chitosan oligosaccharide, fructo oligosaccharide and yeast polysaccharide), and is a functional glycoconjugate for improving sow breeding performance. The functional glycoconjugate can be used as an effective ingredient of a sow feed additive or a premixed feed, belongs to the technical field of agricultural biological products, and comprises the chitosan oligosaccharide, fructo oligosaccharide and yeast polysaccharide. Each ton of feed is added with 20-100g of the chitosan oligosaccharide, 200-1000g of the fructo oligosaccharide and 500-2000 g of the yeast polysaccharide. The components of the functional glycoconjugate are pure biological preparations, free of toxic and side effects, free of residues, less in addition amount, and good in taste palatability. The functional glycoconjugate can alleviate the sow constipation, reduce the damage caused by stress reaction, enhance immunity, and improve the overall health level of sows, and can increase the sow farrowing number, reduce the number of weak piglets and the number of stillbirth, prolong the using life of the sows and significantly improve the number of weaned piglets and the litter weight of the weaned piglets.

Description

technical field [0001] The invention relates to an active ingredient of a feed additive for sows, in particular to an active ingredient of a feed additive for improving the reproductive performance of sows. The invention belongs to the technical field of agricultural biological products. Background technique [0002] At present, the problem of low reproductive capacity of sows is common in China's pig industry. It is mainly manifested in the high elimination rate of sows, low estrus rate, low breeding success rate, long interestrus time, etc., and finally manifested in the small number of litters and poor quality of piglets. In the case of the same slaughter rate of pigs, the low reproductive capacity of sows will greatly increase the production cost of sows, including the increase in the number of sows, as well as the increase in feed costs, labor costs, plant equipment costs and other inputs. [0003] Taking self-propagation and self-raising farms with 10,000 pigs as an ...
