Green pork pig feed capable of increasing lean meat percentage

Abstract

The invention relates to the technical field of livestock breeding and in particular relates to a green pork pig feed capable of increasing the lean meat percentage. The feed is prepared from the following raw materials in parts by weight: 10-12 parts of barley malt, 65-70 parts of corn, 12-15 parts of coarse rice powder, 10-12 parts of dried distillers' grains, 10-12 parts of cooked sweet potatoes, 8-12 parts of dried green bean shells, 5-8 parts of dried corn stigmas, 10-12 parts of tomato seed pulp, 12-15 parts of bean pulp, 8-12 parts of carrot residues, 2-3 parts of fresh small carps, 6-8 parts of wax gourd peels, 2-3 parts of meat and bone meal, 2-3 parts of stachyose, 6-8 parts of alligator alternanthera, 8 parts of silphium perfoliatum, a proper quantity of salt and 4-5 parts of a phagostimulant. According to the feed, the raw materials such as the dried corn stigmas, the carrot residues, the alligator alternanthera and the silphium perfoliatum are added, so that the palatability of the feed is improved, the body weight of pig groups is effectively controlled, the overweight of the pig groups is avoided, the lean meat percentage of the fed pig groups is increased, the ketone body fat rate is reduced, and the pork edible value is high; all the raw materials are pure natural green, and the drug residue problem is avoided.

Description

technical field [0001] The invention relates to the technical field of poultry and livestock breeding, in particular to a green pig feed with improved lean meat rate and a preparation method thereof. Background technique [0002] In the process of large-scale intensive pig raising, in order to speed up the daily weight gain of pigs and shorten the slaughter cycle, many farms often add too high a proportion of protein raw materials and energy raw materials to the feed, while minerals, vitamins and other elements are relatively low. Lack of it leads to overfat pigs, poor quality of ketone bodies, and low lean meat percentage of pork. This not only increases the cost of breeding, but also reduces the market value of pork. The reasonable way to solve this problem is to change the feed formula and pay attention to trace amounts The supplement of elements, on the basis of ensuring the normal growth of pigs, increases the lean meat rate to increase the food value.
