Pig feed at later stage of fattening and its using method

Abstract

The invention discloses a feedstuff for pigs in the later period of fattening and belongs to the technical field of cultivation; the ingredients and the percentage of the feedstuff for pigs in the later period of fattening are: 57 to 60 percent of corn, 13 to 14 percent of soybean pulp, 22 to 24 percent of bran, 0.5 to 1.5 percent of fish meal, 0.4 to 0.5 percent of salt, 2.7 to 3.2 percent of zeolite and 0.0075 to 0.009 percent of compound vitamins; experiment proves that in the later 10 to 20 days of fattening, the use of the feedstuff for pigs of the invention has no effect on the growth performance and carcass composition, the quality of pork is better with better index of pork color, marbling, pH, intramuscular fat content, rate of cooked pork and diameter of muscle fiber, etc., and the quality of the muscle of pigs has a certain improving effect; the contents of calcium, phosphorus and copper in liver and muscle are reduced with different degrees, especially the content of the copper in the muscle is reduced by 25.17 to 40.21 percent obviously, and the cost of the feedstuff is low.

Description

technical field [0001] The invention relates to a late fattening pig feed and an application method thereof, belonging to the technical field of breeding. Background technique [0002] my country is a large animal husbandry country. With the improvement of people's living standards, the quality and safety requirements of pork products are getting higher and higher. Therefore, the use of environmentally friendly feed and the production of green pork have become a top priority. Minerals are nutrients to maintain the normal growth and metabolism of pigs, especially high copper has growth-promoting and antibacterial effects. At present, minerals are always added in excess in pig production, which not only increases the cost of feed, but also burdens the metabolism of the pig body, and the excessive phosphorus, copper, and sulfur in the excreta will also pollute the environment, while minerals such as copper, phosphorus, etc. The residues in pigs will also increase, which makes ...

Problems solved by technology

At present, minerals are always added in excess in pig production, which not only increases the cost of feed, but also burdens the metabolism of the pig body, and the excessive phosphorus, copper, and sulfur in the excreta will also pollute the environment, while minerals such as copper, phosphorus, etc. The residues in pigs will also increase, which makes pork products unsafe and affects the health of consumers, which also causes a waste of mineral resources to a certain extent
