Feed for promoting skeleton growth of black pigs and preparation method of feed

Abstract

The invention discloses a feed for promoting skeleton growth of black pigs and a preparation method of the feed. The feed is prepared from the following raw materials in parts by weight: 240-260 parts of rice, 120-140 parts of duck wheat, 50-70 parts of sweet potato residues, 180-190 parts of extruded soybeans, 150-180 parts of maize meal, 70-80 parts of goat liver powder, 80-90 parts of hoof and horn meal, 70-80 parts of ryegrass, 60-70 parts of alfalfa, 30-40 parts of pineapple peel, 20-30 parts of bagasse, 30-40 parts of garlic leaves, 10-20 parts of pomegranate flowers, 20-30 parts of vegetable juice, 2-3 parts of brown sugar, 10-15 parts of fresh milk, 8-9 parts of walnuts, 7-8 parts of fructus amomi, 10-15 parts of freeze-dried pumpkin powder, 10-15 parts of fishbone meal, 8-10 parts of shell powder and 2-3 parts of black pig nutrients. The feed is fine in production, safe, rich in nutrition and crisp in taste; the skeleton growth of black pigs can be promoted; the skeletons of the black pigs fed by the feed are hard and are rich in elasticity and toughness; the growth and fattening of the black pigs are accelerated; the pig body hair color and the quality of pork can be improved; the immunity of the black pigs and the utilization rate of the feed are improved.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, in particular to a black pig skeleton growth-promoting feed and a preparation method thereof. Background technique [0002] my country is the largest pig raising and pork production country in the world. The breeding, slaughtering, processing and consumption of live pigs are not only an important symbol to measure a country's civilization level and people's quality of life, but also important factors in China's agricultural economy and import and export trade. Occupying a pivotal role, the stable development of pig breeding and slaughtering industries directly affects the formulation of national policies and strategies. At present, the breeds of pigs bred in my country mainly include Duroc, Large White, Landrace, Yorkshire, Poland, and Black. Compared with ordinary pigs, black pigs have characteristics and advantages that cannot be compared with ordinary pigs. . [0003] First of all, ...

Problems solved by technology

First, there is a lack of special breeding feed in the field of black pig breeding, and farmers often use general-purpose pig feed and other pig feed to replace it. This approach is very unscientific, so it is difficult to improve the breeding efficiency of black pigs; There are many hidden dangers in the safety of common pig feed, which may contain unsafe additives. After eating black pigs, it will affect their growth and later production performance; third, the use of unsafe feed will not only affect the product quality and The taste of the meat will reduce the sales profit, and it will also threaten the health of the people
