Feed additive for improving production performance of lactating sows, preparation method and application thereof

Abstract

The invention relates to a feed additive for improving the production performance of lactating sows, a preparation method and application thereof, and belongs to the technical field of sow feeding. The above-mentioned feed additives include enteromorpha, pyrroloquinoline quinone, kelp, motherwort, buliuxing, malt, brown sugar, licorice, purslane, Bupleurum and compound amino acids. Its preparation method includes: mixing kelp, motherwort, blancia, malt, brown sugar, licorice, purslane and Bupleurum, decocting, concentrating, and mixing with enteromorpha, pyrroloquinoline quinone and compound amino acids. The preparation method is simple, low in cost and good in controllability. The prepared feed additive can effectively improve the immune level of lactating sows and promote lactation; and its raw materials are all green additives, which are safe and environment-friendly. Applying it to the feed of lactating sows can pass benefits through the mother and offspring, improve the health status of suckling piglets, improve the growth performance of piglets and the economic benefits of breeding.

Description

technical field [0001] The invention relates to the technical field of sow feeding, and in particular to a feed additive for improving the production performance of lactating sows, a preparation method and application thereof. Background technique [0002] China's pig breeding accounts for more than 50% of the world's total, and it is a big and powerful pork consumer. However, the production performance of Chinese pigs is far lower than that of Europe and the United States. There is still a lot of room for improvement in China's breeding technology, especially for sows. feeding management. Most of the domestic breeds are Duroc, Landrace and Large White pigs, and most of the commercial pigs are Du long-term three-way hybrid pigs. The three-way hybrid pigs grow fast, have a low feed-to-meat ratio and a high slaughter rate. However, the genetic traits in terms of lactation ability, conception rate and litter rate have been reduced, and the production performance of local breed...

Problems solved by technology

[0004] At present, with the continuous acceleration of the process of intensive pig breeding, the sow management level is not advanced, resulting in low estrus rate, low conception rate, low number of live piglets and postpartum syndrome. These phenomena have seriously affected pig breeding. The economic benefits of households, in order to solve the occurrence of this situation, the use of antibiotics to treat various diseases of postpartum sows and newborn piglets is a common method nowadays, but antibiotics are often used, due to the long-term, overdose, and Unreasonable use, the problem of drug resistance of pathogenic bacteria is becoming more and more prominent. The emergence of drug resistance means that the disease is more difficult to treat for sick animals, and it means greater breeding risks and costs for livestock producers, which seriously threatens livestock, poultry and human beings. Therefore, it is particularly important to find anti-antibiotic breeding techniques to enhance the health of sows and suckling pigs
