Low-protein mule duck feed for balancing amino acid and preparation method of feed

Abstract

The invention provides a low-protein mule duck feed for balancing amino acid. The feed comprises a component A and a component B, wherein the component A is prepared in such a way that compound probiotic strains are activated by brown sugar water and then inoculated in a mixture of pulverized corn, rice bran, wheat bran, peanut meal, rapeseed meal, soybean meal, calcium hydrophosphate and table salt, and the mixture is added and mixed with water and then packed in a vacuum bag to ferment 7 days at constant temperature; the component B comprises corn, broken rice, wheat, soybean meal, cottonseed meal, coleseed meal, rice bran, wheat bran, stone powder, calcium hydrophosphate, table salt, a microelement premixture, a vitamin premixture, L-lysine hydrochloride, DL-methionine and phytase wheat enzyme; at the age of 1-3 weeks, the component A and the component B are mixed at the weight part ratio of (15-40):(60-85); at the age of 4-8 weeks, the component A and the component B are mixed at the weight part ratio of (5-15):(85-95). The feed provided by the invention activates the digestion potential of mule ducks, improves feed transformation efficiency, exploits the growth potential of the mule ducks and saves protein resource.

Description

technical field [0001] The invention belongs to the category of animal husbandry, and mainly relates to animal nutrition feed and its preparation. Specifically, it is a low-protein balance amino acid microbial complete feed suitable for muscovy ducks prepared by using cheap resources as energy and protein raw materials and a preparation method thereof. Background technique [0002] With the improvement of living standards and the enhancement of health awareness, people pay more and more attention to food safety, sensory quality and health care function, and the pursuit of duck products has changed from quantity to quality, that is, the pursuit of quality. The half muscovy duck is a kind of meat duck produced by crossing a male muscovy duck with a meat duck with better performance. It has obvious heterosis, strong disease resistance, coarse grain tolerance, more leg meat, less fat, The meat is of excellent quality. Muscovy duck not only overcomes the shortcomings of high bo...

AI Technical Summary

Problems solved by technology

[0004] Due to the lack of research on the physiology and biochemistry, nutrition, feeding and feed preparation technology of Muscovy Duck in my country, there is also a lack of scientific basis and unified nutritional standards for the preparation of Muscovy Duck feed. At present, most of the domestic production of Muscovy Duck feed uses general Muscovy ducks are different from Muscovy ducks and domestic ducks, and their nutritional needs are also different, so the feeding requirements for raising Muscovy ducks are also different; Breeding Muscovy ducks with the standard of common meat duck feed, It does not meet the nutritional and physiological characteristics of muscovy ducks, but also increases the cost of feeding, resulting in a large waste of resources
