Embodiment 1

[0016] Weigh 76.4kg of corn, 5kg of bran, 14.6kg of soybean meal, 4kg of premix, 0.1594kg of lysine, and 0.003kg of methionine.

[0017] The corn, bran, and soybean meal are superfinely pulverized, and after the pulverized materials are evenly mixed, the premix, lysine, and methionine are added and mixed evenly.

Embodiment 3

[0019] Corn 70.5kg, bran 5.2kg, soybean meal 18kg, fish meal 2kg, soybean oil 0.3kg, premix 4kg, lysine 0.1871kg, methionine 0.03258kg.

[0020] The preparation method is the same as in Example 1.

Abstract

The invention provides a high-efficiency and low-nitrogen finishing pig feed. The finishing pig feed comprises the following components, by weight, 70.5-76.4 parts of corn, 5-5.2 parts of wheat bran, 14.6-18 parts of soybean meal, 4 parts of a premix, 0.1594-0.1871 parts of lysine, 0.003-0.03258 parts of methionine. According to the present invention, the components of the finishing pig feed and the amount of the components are blended reasonably while proper and proper amount of the amino acids are added to the finishing pig feed, such that the formula of the finishing pig feed substantially meets physiological requirements and growth requirements of the finishing pigs; with synergistic reactions generated among all the components of the formula, utilization rate of the feed protein is raised, feed conversion efficiency is improved, feed cost is reduced, ammonia excretions in pig manure and pig urine are reduced, ammonia pollution to the environment from the intensive livestock farming production is reduced.

Description

technical field [0001] The present invention relates to animal feed, in particular to a feed especially suitable for fattening pigs. Background technique [0002] China is the largest pig raising country in the world, and the annual pig production accounts for about 50% of the world's total pig production. As the main source of animal protein for urban and rural residents in my country, pork accounts for about 65% of the total meat consumption. It plays an important role in ensuring social stability and improving people's living standards. However, with the rise of intensive pig farming, the number of live pigs has increased rapidly in the past three decades. As of 2008, large-scale pig farming (more than 50 sows) has accounted for about 50% of the total, and the number of sows that can reproduce in the country is nearly 050 million, with 490 million pigs on hand at the end of the year, and about 600 million pigs for slaughter each year. It is not difficult to see from thi...
