Embodiment 1

[0091] A kind of feed for growing and fattening pigs with low protein The formulation of the feed is composed as follows (mass percentage): 80.26% of corn, 15.88% of soybean meal, 1.325% of stone powder, 0.20% of soybean oil, 0.61% of calcium hydrogen phosphate, 0.35% of salt, and 0.48% of lysine %, threonine 0.15%, tryptophan 0.04%, valine 0.10%, methionine 0.10%, isoleucine 0.02%, trace element premixed feed 0.20%, vitamin premixed feed 0.03%, choline chloride 0.15%, acid phytase 0.005% (equivalent to 500U / kg feed), neutral phytase 0.1% (equivalent to 2000U / kg feed). Grinding and mixing the above-mentioned feed raw materials, and processing them according to the conventional production process, can obtain the low-protein feed for growing and finishing pigs that can improve the quality of pig carcass. pig.

Embodiment 2

[0093] A kind of feed for growing and fattening pigs with low protein The formulation of the feed is composed as follows (mass percentage): 83.16% of corn, 12.90% of soybean meal, 1.37% of stone powder, 0.39% of calcium hydrogen phosphate, 0.405% of zeolite powder, 0.35% of salt, 0.50% of lysine %, threonine 0.16%, tryptophan 0.04%, valine 0.09%, methionine 0.10%, isoleucine 0.05%, trace element premixed feed 0.2%, vitamin premixed feed 0.03%, choline chloride 0.15%, acid phytase 0.005% (equivalent to 500U / kg feed), neutral phytase 0.10% (equivalent to 2000U / kg feed). Grinding and mixing the above-mentioned feed materials evenly, and processing according to the conventional production process, can obtain the low-protein feed for growing and finishing pigs that can improve the quality of pig carcass. pig.

Embodiment 3

[0095] A low-protein pig feed for growing and fattening. The formula of the feed is as follows (mass percentage): 81.62% of corn, 3.16% of soybean meal, 6.00% of bran, 3.00% of rapeseed meal, 1.22% of soybean oil, 1.25% of stone powder, and 0.25% of calcium hydrogen phosphate , Zeolite powder 1.595%, salt 0.35%, lysine 0.55%, threonine 0.19%, tryptophan 0.06%, valine 0.11%, methionine 0.06%, isoleucine 0.10%, trace element premix feed 0.20%, vitamin premix feed 0.03%, choline chloride 0.15%, acid phytase 0.005% (equivalent to 500U / kg feed), neutral phytase 0.10% (equivalent to 2000U / kg feed). Grinding and mixing the above-mentioned feed materials evenly, and processing according to the conventional production process, can obtain the low-protein feed for growing and finishing pigs which can improve the carcass quality of pigs. pig.

Abstract

The invention discloses a growing-finishing pig low-protein feed capable of improving carcass quality of pigs and a feed additive. The growing-finishing pig low-protein feed is added with 500U/kg to 10000U/kg of acid phytase and 500U/kg to 10000U/kg of neutral phytase. Compared with the conventional low-protein feed, the low-protein feed disclosed by the invention has the advantages that the backfat thickness of growing-finishing pigs can be reduced, the lean meat percentage can be increased, the carcass quality can be improved, the adverse effect of the conventional low-protein feed on the carcass quality of pigs can be eliminated, and the popularization and application of the low-protein feed technology in production can be facilitated.

Description

technical field [0001] The application relates to a pig feed and a feed additive, in particular to a low-protein feed and a feed additive for growing and finishing pigs that improve the carcass quality of pigs. Background technique [0002] With the growth of population and the improvement of people's living standards, the demand for animal food is increasing. Since the implementation of the "Vegetable Basket Project" in my country in the 1980s, the animal husbandry has developed rapidly and basically solved the problem of animal food supply. However, at the same time, new problems such as the shortage of protein feed resources and the pollution of the breeding environment have become increasingly prominent. . At present, the domestic production of soybeans, the raw material for protein feed and soybean meal, which is the most used protein in the breeding industry, is seriously insufficient, mainly relying on imports. In 2017, my country's total demand for soybeans, includi...
