Meat duck feed containing vinegar residues

Abstract

The invention relates to a meat duck feed containing vinegar residues and belongs to the technical field of stock raising feed production. The meat duck feed comprises vinegar residues and complex enzyme preparations, wherein the complex enzyme preparations include cellulose 1200-1800U, xylanase 25000-35000U, mannose 40-60U, protease 8000-12000U, pectinase 180000-250000U, glucanase 3000-5000U, the balance being carriers, and the carriers are dehydrated corncob powder. According to characteristics of vinegar residues, reasonable varieties and ratio of exogenous digestive enzyme are designed, digestibility of vinegar residues is increased, the function of anti-nutrition is reduced while digestible nutrient concentration of vinegar residues is increased, the growth performance is not decreased while costs are reduced when the feed is used, and the scheme of utilizing vinegar residues to reduce cultivation costs in meat duck breeding is feasible. Besides, a proper amount of fibers can promote growth and development of gizzards and intestines of meat ducks, and individually selling duck intestines can further increase economic benefits and economic value added in meat duck breeding.

Description

technical field [0001] The invention relates to a feed, in particular to a meat duck feed containing vinegar grains, and belongs to the technical field of livestock feed production. Background technique [0002] Meat duck is a poultry with fast growth, high feed remuneration, high meat production, good meat quality, high lean meat rate and strong adaptability, and occupies an important position in the world's meat and poultry. Duck meat is tender and delicious, rich in nutrition, and contains about 30% protein, which is 3-8 percentage points higher than beef, mutton and pork. Duck meat has low fat content, especially the lowest cholesterol content in meat, and is a relatively healthy meat product. At the same time, duck mushroom liver and duck intestines have unique flavors and are also people's favorite food. [0003] In recent years, due to the shortage of food in the world and the development of the feed industry, the prices of feed materials such as corn, soybean meal, ...

Problems solved by technology

[0014] The present invention aims to solve the problem that the crude fiber content of vinegar grains in the prior art is high, and the ability of monogastric animals to digest fiber is limited. At the same time, a higher fiber level will speed up the peristalsis of the intestinal tract, reduce the digestibility of food, and slow down the growth rate. To solve the problem of increased weight gain ratio of feed consumption, provide a meat duck feed containing vinegar grains, which greatly improves the digestibility, and at the same time can promote the growth of duck intestines, increasing its economic added value
