Meat duck compound feed with nitrogen emission reduction function and preparation method of meat duck compound feed

Abstract

The invention discloses a meat duck compound feed with a nitrogen emission reduction function and a preparation method of the meat duck compound feed. The meat duck compound feed comprises the following components in percent by weight: 50-65 percent of corn, 4-15 percent of barley, 4-24 percent of bean pulp, 0-10 percent of rapeseed dregs, 3-10 percent of vinegar residue, 0.1-0.25 percent of methionine, 0.1-0.25 percent of lysine, 0.05-0.15 percent of choline, 1-2 percent of calcium hydrophosphate, 0.6-1 percent of mountain flour, 0.1-0.6 percent of vitamin premix and 0.1-0.6 percent of microelement premix. According to the meat duck compound feed disclosed by the invention, through regulating components and contents of meat duck compound feed, the nitrogen emission in a meat duck raising process is reduced when the growth performance of a meat duck is not influenced, thus the feed cost of the meat duck can be reduced, the pollution of meat duck raising to the environment can be greatly reduced, and a good economic benefit and a social benefit are achieved.

Description

technical field [0001] The invention relates to a meat duck compound feed and a preparation method thereof, belonging to the technical field of feed products, in particular to a meat duck compound feed with nitrogen emission reduction function and a preparation method thereof. Background technique [0002] my country is the largest duck producer in the world. In recent years, under the situation of rapid economic development, the scale of meat duck breeding has expanded rapidly, and the stock and slaughter of meat ducks have increased at an average annual rate of 5% to 8%. According to the statistics of the Food and Agriculture Organization of the United Nations (FAO), in 2009, the number of ducks in stock in the world was 1.173 billion, of which the stock of ducks in my country was 771 million, accounting for 65.7% of the total stock in the world. In 2011, the stock of meat ducks in my country reached 1.525 billion, and 3.94 billion ducks were slaughtered, accounting for m...
