Soybean-meal-free laying-hen compound feed and preparation method thereof

Abstract

The invention provides a soybean-meal-free laying-hen compound feed and a preparation method thereof. The soybean-meal-free laying-hen compound feed is formed by mixing the following ingredients by weight percent: 50 to 65 percent of corns, 5 to 10 percent of cotton meal, 1 to 5 percent of vegetable meal, 5 to 10 percent of DDGS, 1 to 4 percent of corn protein powder, 2 to 5 percent of hydrolyzed feather powder, 8 to 11 percent of middling flour and 3 to 6 percent of auxiliary additives. The invention provides the soybean-meal-free laying-hen compound feed in which nutrients are balanced and an ideal protein AA balance technology is adopted, appropriate miscellaneous meal enzyme is added and miscellaneous meal is adopted to completely replace the soybean meal; the invention also provides a preparation method of the soybean-meal-free laying-hen compound feed.

Description

technical field [0001] The invention belongs to the technical field of animal nutrition and feed processing, and relates to a feed formula and a preparation method thereof, in particular to a soybean meal-free compound feed for laying hens and a preparation method thereof. Background technique [0002] For a long time, the diet structure of livestock and poultry has been a typical corn-soybean meal type, and soybean meal has been used as the main source of protein feed for various feeds, resulting in increasingly tight supply of soybean meal, and even more than 80% of the raw material soybean of soybean meal depends on imports. Frequent and drastic changes in the soybean market lead to large fluctuations in the price of livestock and poultry feed, seriously affecting the healthy and sustainable development of the feed industry and breeding industry. Miscellaneous meal, as an alternative protein feed resource for soybean meal, mainly comes from domestic sources and basically ...

Problems solved by technology

[0002] For a long time, the diet structure of livestock and poultry has been a typical corn-soybean meal type, and soybean meal has been used as the main source of protein feed for various feeds, resulting in increasingly tight supply of soybean meal, and even more than 80% of the raw material soybean of soybean meal depends on imports. The frequent and drastic changes in the soybean market lead to large fluctuations in the price of livestock and poultry feed, seriously affecting the healthy and sustainable development of the feed industry and the breeding industry

Miscellaneous meal, as an alternative protein feed resource for soybean meal, mainly comes from domestic sources and basically does not rely on foreign imports. The price of most miscellaneous meal is lower than that of soybean meal, but it has the characteristics of AA imbalance. Simple substitution will lead to a decrease in nutrient digestibility and Decline in performance of laying hens

There are many studies on the application of miscellaneous meal to replace part of soybean meal in laying hen diets at home and abroad, but there are few researches and applications on the use of whole miscellaneous meal rations without soybean meal in laying hen feed
