Growing-finishing pig composite pre-mixing feed

Abstract

The invention relates to a growing-finishing pig composite pre-mixing feed, belonging to the feed field, comprising: amino acid additive, inorganic trace element and organic trace element, vitamin additive, magnesium sulfate, bean pulp, functional additive, wherein the organic trace element comprises organic chrome, organic selenium, the amino acid additive comprises lysine and threonine, the functional additive comprises cysteine hydrochloride coated by cyclodextrin, dihydropyridine ester, enzyme preparation, probiotics. The feed can increase the digestion and absorption of nutritive material and daily gain and feed utilization rate, reduce marketing period; improve feed efficiency, reduce feed conversion ratio (the feed conversion ratio of the common feed is 0.2-0.4), greatly save the cultivation cost; increase muscle lipid content and meat flavor; reduce drip loss and improved meat taste.

Description

technical field [0001] The invention relates to a compound premixed feed used for growing and fattening pigs from 50 kg to slaughter. The added amount is 6%, and the product name is "Yi Jia Neng". The customer mixes it with corn, soybean meal, and bran to make a full-price feed for growth. Used for fattening pigs. Background technique [0002] my country is the world's largest pig raising country and the second largest feed production country in the world, in which pig feed accounts for more than 40% of the total. The feed industry occupies an important position in the national economy and is directly related to the quality of people's living standards and physical health However, there is a large gap in the overall level of my country's feed industry compared with Western developed countries. The main reason is that the research on key industrialization technologies of pig feed production in developed countries in Europe and the United States is extensive and in-depth, and t...

Problems solved by technology

[0003] A pig will consume 300kg of feed when it grows to 110kg, and 70% of the feed will be consumed from 50kg to slaughter. Therefore, the feed cost at this stage is an important investment for the pig farm. If the feed cost of growing and finishing pigs can be reduced and growth can be improved The growth rate of fattening pigs can greatly improve the economic benefits of pig farms; at the current average level in China, it takes about 180 days for a pig to reach 100kg, and the average feed-to-meat ratio from weaning to 110kg for slaughter is about 3.0. For some pig farms, due to the slow growth rate of pigs and the long feeding cycle, the utilization rate of pig farms is low. Often because a large number of pigs do not have enough space to raise them, the stocking density is artificially increased, and the growth rate is indirectly caused. The slowing down of the speed increases the difficulty of the shed, the feed consumption increases, and the ratio of feed to meat is high, resulting in a vicious circle
