DDGS type mixed feed for meat ducks aged in 0-13 days, 14-27 days and 28-39 days and preparation method thereof

Abstract

The invention discloses a DDGS type mixed feed for meat ducks aged in 0-13 days, 14-27 days and 28-39 days and a preparation method thereof. The DDGS type mixed feed comprises a 0-13-day meat duck feed, a 14-27-day meat duck feed and a 28-39 day meat duck feed. The DDGS type mixed feed has the beneficial effects that through addition of corn DDGS and phytase, the amount of calcium hydrophosphate in the feed is reduced, the metabolism of nitrogen and phosphorous in the feed is promoted, the discharge of nitrogen and phosphorous in faeces is lowered, the amount of corn DDGS of corn byproducts is obviously improved, protein feed resources are saved, the feed utilization rate is improved, the feed cost is reduced, and economic benefits are improved; nutritional demands of 0-39-day meat ducks can be met, the production capability of the meat ducks is improved, the nutritional value demands of the meat ducks are met, and the daily gain of the meat ducks can be improved; the nutrition intake proportion of the meat ducks is improved; in addition, traditional Chinese medicine additives are added, and thus the DDGS type mixed feed is capable of promoting digestive absorption and reducing intestinal tract pathogenic bacteria.

Description

technical field [0001] The invention relates to a duck compound feed, in particular to a DDGS type meat duck compound feed of three stages of 0-13 days old, 14-27 days old, and 28-39 days old and a preparation method thereof. Background technique [0002] my country is the largest meat duck breeding country in the world, and the demand for meat duck products in my country is also increasing year by year. Therefore, the feed preparation technology for meat ducks has become the key to ensure the efficient production of meat ducks. The formula of meat duck feed should be based on the nutritional needs of meat duck, the nutritional value of feed raw materials, the quality status of raw materials, production costs and market demand to reasonably determine the ratio of various feed raw materials. Conventional protein raw materials such as soybean meal, fish meal, rapeseed meal, cotton meal, etc. are good sources of protein for meat ducks. However, under the current situation of...
