Feed for reserved sows, and preparation method and application thereof

Abstract

The invention discloses a feed for reserved sows. The feed is prepared from the following components: corn, sorghum, bran, rice bran, grass meal, soybean meal, sunflower meal, corn germ meal, shell powder, fish meal, mushroom, decavitamin, a composite multi-mineral, and a core additive. The core additive is prepared from the following components: motherwort herb, herba epimedii, dodder, garlic, wolfiporia extensa, houttuynia cordata, and cnidium monnieri. The feed for the reserved sows can provide basic nutrients for the reserved sows; at the same time, with the addition of the core additives, the feed can guarantee the reserved sows have stronger breeding ability during a breeding period, and also can improve own immunity of the reserved sows; and the feed has the advantages of high security, wide raw material sources and low price.

Description

Technical field [0001] The invention relates to a pig feed, in particular to a feed for improving the reproduction ability of sows in the reserve period. Background technique [0002] The sow in the reserve period is the sow that is reserved for breeding, from weaning to before entering the breeding stage. Cultivating sows in the reserve period is one of the important conditions for high and stable production of pigs. During the feeding process of the sow in the reserve period, it is necessary to prevent the growth of too fast and fat, but also to prevent the growth of too slow and stunted growth. The way to prevent sows from growing too fast and too slowly in the reserve period is usually to control their nutritional levels. Since the sow in the reserve period plays a role in the whole pig industry, the quality of the sow in the reserve period not only affects the litter size and birth weight of the first litter, but also affects the performance of multiple births in the futur...

AI Technical Summary

Problems solved by technology

[0003] At present, the feed for gilts in the gilt period is usually fattening pig feed. The main problems are: 1. Only pay attention to the general components such as crude protein and digestible energy, while ignoring the key components that affect reproductive performance; 2. The body weight is too small when mating Or too large, the former sows have insufficient basic nutrient reserves, and the backfat is quickly exhausted after farrowing, which exposes problems such as insufficient breast milk. production levels; the latter can lead to prolonged or absent estrus, low service pregnancy rates, and low fecundity
