Feed for improving reproductive performance of lactating sow and preparation method thereof

Abstract

The invention discloses feed for improving reproductive performance of a lactating sow. The feed comprises the following components as raw materials in parts by weight: 50-60 parts of corn, 20-23 parts of soybean meal, 6-15 parts of bran, 6-12 parts of rice bran, 0.1-1 part of calcium hydrogen phosphate, 0.5-2 parts of stone powder, 0.1-1 part of table salt, 0.01-0.1 part of trace elements, 0.01-0.1 part of vitamins and 1-6 parts of a pomace fermentation material. The invention further discloses a preparation method of the feed. The feed for enhancing the reproductive performance of the sow isprepared by mixing the pomace fermentation material and the other raw materials according to a specific formula and the specific preparation method, and the feed can significantly improve the digestive capacity and the nutrient absorbing capacity of the sow to improve the physique of the sow and promote rapid reproduction of the sow so as to achieve the purpose of improving the reproductive performance of the sow; and when the sow is fed during the first three months of pregnancy and during weaning, the number of live births of the sow is significantly increased, the lactating capacity is significantly improved and the number of weaned piglets is significantly increased, so that the reproductive performance of the sow is improved.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a feed for improving the reproductive performance of lactating sows. Background technique [0002] Lactating sows are the core of large-scale and intensive pig production management. At this stage, sows must not only secrete sufficient milk to feed piglets, but also must store the necessary nutrients for re-breeding. Therefore, the quality of the nutritional status of sows during lactation not only directly affects the growth performance of piglets, but also relates to the service life of sows and the economic benefits of pig farms. The reproductive performance of the exotic breeds raised in the current intensive pig farms is generally poor, coupled with the lack of management level and the limitation of production conditions, there is a certain gap between the current production capacity and the world's advanced level. Sows have a large demand for various nutrients during p...

Problems solved by technology

Since the normal production life span of sows is much longer than that of fattened pigs, harmful substances in feed are more likely to accumulate in the body, and some feed toxins will directly affect the reproductive system of sows; in addition, sows have different nutritional requirements in different physiological stages. Larger, malnutrition problems caused by unreasonable feed preparation are prone to occur in production, which will cause the body's immunity to decline, making it more susceptible to some reproductive disorders such as blue ear disease, swine fever, pseudorabies, etc.

Since the normal reproductive function of sows depends on the regulation of reproductive endocrine hormones, if production measures cannot be taken early for reasonable feeding and management, once serious reproductive obstacles are caused, it will be difficult to restore normal reproductive performance in a short time; and if the ratio Unreasonable and prone to toxic effects on pregnant sows and fetuses

However, there is currently no effective feed modification for this phenomenon
