Nutrient for improving productivity of nursing sows and preparation method thereof

Abstract

The invention discloses nutrient for improving productivity of nursing sows and a preparation method thereof. The nutrient for improving productivity of nursing sows comprises, by weight, 5-20 parts of Angelica acutiloba root, 10-25 parts of Astragalus root, 5-25 parts of cowherb seed, 5-20 parts of beautiful sweetgum fruit, 10-25 parts of hawthorn fruit, 10-25 parts of malt, 5-25 parts of dried orange peel, 5-25 parts of medicated leaven, and 10-25 parts of motherwort. The preparation method includes cleaning pharmaceutical materials, and drying and crushing to obtain powders of the pharmaceutical materials; weighing the crushed powders of the pharmaceutical materials according to a ratio of the nutrient, mixing well, and subpackaging. By the use of the nutrient for improving productivity of nursing sows, milking ability of sows can be improved effectively, anorexia and constipation in sows can be avoided, normal oestrus of the sows after weaning is promoted, and yellow and white scours of newborn piglets are reduced.

Description

technical field [0001] The invention relates to a veterinary traditional Chinese medicine composition, in particular to a nutritional agent for improving the production performance of lactating sows and a preparation method thereof. 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, 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, quite strict feeding and management conditions are required. Each stage of the reproductive cycle must specify corresponding nutrition...

AI Technical Summary

Problems solved by technology

In addition, the types of feed for sows are becoming less and less, and the types of nutrients are becoming more and more monotonous. Sows raised under natural conditions can ingest tens of thousands of nutrients, and the sows can be used for more than ten years; and now large-scale breeding The types of nutrients that the sows in the factory are exposed to are only dozens of types, resulting in the amount of nutrients that the sows eat remain unchanged, but the types are less and less, so the consequences are seriously deviated from the natural nature of the sows. As a result, the physiological, psychological and body conditions of sows will change greatly during the reproductive cycle, the incidence of reproductive disorders will increase, the service life will be seriously reduced, and the production performance will be seriously affected, which will eventually increase the cost of large-scale breeding.

[0003] Similarly, lactating sows in large-scale farms also face certain problems: in the process of pig production, sows suffer from production stress due to lack of nutrition, and often suffer from constipation, mastitis, metritis, puerperal fever, and postpartum lactation. Insufficient lactation, emaciated lactation, lack of estrus after weaning or even no estrus, many piglets born with yellow and white scour, low weaning weight, low survival rate, etc.
