Fodder for first-born lactating sows, and preparation method and application thereof

Abstract

The invention discloses a fodder for first-born lactating sows. The fodder is prepared from the following components: corn, defective flour, bran, two-eight rice bran and hull, alfalfa meal, sunflower meal, cassava, silkworm chrysalis powder, fish meal, bone meal, shell powder, an antioxidant, decavitamin, a composite multi-mineral, and a core additive. The core additive is prepared from the following components: tetrapanax papyriferus, radix rhapontici, vaccaria segetalis, radix scutellariae, echinacea purpurea, radix rehmanniae preparata, radix polygoni multiflori, and radix isatidis. The fodder for the first-born lactating sows can provide basic nutrients for the lactating sows; at the same time, with the addition of the core additive, the fodder can guarantee that the lactating sows have more milk during lactation, and also can improve lactating sow own immunity; the fodder has high security, wide raw material sources and low price; and with the addition of the antioxidant, the fodder can enable the lactating sows to recover better during the lactation process and after giving first birth.

Description

technical field [0001] The invention relates to a feed for pigs, in particular to a feed for first-born lactating sows and a preparation method and application thereof. Background technique [0002] Lactation is a unique function and biological characteristic of all mammals. The main purpose of feeding rice on schedule is to improve the lactation volume and milk quality of sows, and to obtain ideal piglets; at the same time, to ensure the health of the mother, to be able to normally estrus, ovulate, and lose weight moderately in the next reproductive cycle. [0003] In the modern pig industry, postpartum weight loss of sows has always troubled the majority of farmers. The reason is that lactating sows not only need to maintain their own life needs, but also need to restore their prenatal body condition after delivery, and also provide milk for piglets; at the same time , the sow's resistance is reduced, and the susceptibility to disease not only affects its own milk product...

AI Technical Summary

Problems solved by technology

[0005] However, the existing feeds for first-born lactating sows generally lack systematic thinking in feed preparation, and do not comprehensively consider the latest sow nutritional progress, the relationship between nutrition and environment, nutrition and stress, etc., and it is difficult to improve the health of sows. Lactating ability

[0006] In addition, the body weight of the first-parity sow is still increasing, and the reproductive organs are still developing, so the nutritional requirements are different from those of the multiparous sows. Feeding the first-parity lactating sows with compound feed during the lactation period of ordinary multiparous sows will cause the sows to lose weight. Pigs lose too much weight during lactation, and the rate of re-estrus within one week after weaning is low, so the total lifespan is short; piglets have low birth weight and weaning weight, high mortality, poor reproductive performance of first litter sows, and low body condition affects sows' lifetime reproduction Performance, thus affecting the total number of slaughtered pigs per sow, greatly reducing the economic benefits of the entire pig farm
