Problems solved by technology

my country is a big consumer of pork. The rapid development of the pig industry over the past 30 years has mainly relied on the introduction of foreign pig breeds, binary or ternary hybridization for fattening. The imported pig breeds have high lean meat percentage, fast growth rate, and high feed conversion rate. But it is not resistant to rough feeding, and the meat quality is poor, while the local pig breeds in my country have the characteristics of good meat quality and resistance to rough feeding, but their growth is slow and their meat yield is low

Abstract

The invention discloses an antibiotic-free crude feed suitable for free-range black pigs and an application of the antibiotic-free crude feed. The antibiotic-free crude feed is characterized by comprising the ration formula components and content of porcine muscle fat deposition after functional conversion. The antibiotic-free crude feed prepared by the method comprises the ration formula components and nutrient value, on one hand, the quality of meat of live pigs can be notably improved, and on the other hand, the nutrient transformation efficiency of the feed of variety pigs can be improved,and the discharge amount of nitrogen, phosphorus, copper and zinc in excrement can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and relates to the application of a diet formula for converting high-end pork intramuscular fat deposition. Background technique [0002] With the transformation of people's demand for meat from quantity to quality, the production of high-quality pork is imminent, and the breed of pig is one of the main factors that determine the quality of meat. my country is a big consumer of pork. The rapid development of the pig industry over the past 30 years has mainly relied on the introduction of foreign pig breeds, binary or ternary hybridization for fattening. The imported pig breeds have high lean meat percentage, fast growth rate, and high feed conversion rate. But it is not resistant to rough feeding, and the meat quality is poor, while the local pig breeds in my country have the characteristics of good meat quality and resistance to rough feeding, but they grow slowly and their meat yield is low...
