Nutritional feed for improving reproductive performance of six-birth postnatal multiparous sows and application thereof

Abstract

The invention provides a nutritional feed for improving reproductive performance of six-birth multiparous sows and an application thereof, which belong to the technical field of livestock breeding, the nutritional feed comprises the following components in parts by weight: 802-1047 parts of a protein calcium phosphate material, 0.1-0.2 part of a Chinese angelica extract, 3-5 parts of compound organic trace elements, 0.3-0.5 parts of compound vitamin, 0.1-0.3 part of an astragalus extract, 0.05-0.1 parts of Jujuboside, 0.1-0.2 part of glycyrrhizic acid, 0.1-0.3 part of vitamin E, and 0.05-0.1 parts of 1,25-hydroxy D3. The nutritional feed provided by the invention has the good effect of improving the breeding capacity of sows after six births, can prolong the breeding period of the sows, greatly reduces the breeding cost of the sows, improves the breeding efficiency of the sows, and is a scientific and technological innovative product.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a nutritional feed for improving the reproductive performance of multiparous sows after 6 parities and its application. Background technique [0002] With the development of China's pig industry, pig farmers pay more and more attention to the nutrition of sows, especially the nutrition of lactating sows has attracted everyone's attention. The company publicizes that sows with more than 6 litters will be eliminated in time, and a large proportion of sows will be updated. In fact, according to the current production capacity of high-breeding sows, a sow should provide pig farmers with more than 80 piglets in a lifetime. However, due to the nutritional problems of sows, the average sow in China can only provide about 50 piglets in a lifetime. The main reasons are: 1. Problems with the nutrition and cultivation of gilts. 20-30% of sows are eliminated before the ...

AI Technical Summary

Problems solved by technology

However, sows after 6 parities have mature physiology and body, and their ability to adapt to the outside world is enhanced. As long as reasonable nutrition is improved according to their age and physiological characteristics, the reproductive performance of sows will be further improved. Pig nutrition is of great significance, but there is no nutritional research on sows with more than 6 parities in the prior art
