Breeding method for increasing estrus rate of of sows of huai black pigs

Abstract

The invention discloses a breeding method for increasing the estrus rate of sows of huai black pigs. The method comprises the following steps of selecting 3-month-old healthy sows, freely drinking water, feeding traditional Chinese medicine mixed feed in the morning, at noon and at night, respectively, moving once before and after each meal, and averagely moving for 20-30 minutes each time; controlling the temperature of a sow habitat to be 24-26 DEG C, and keeping illumination for at least 10 h every day; when the sows are 5 months old, feeding the sows with compound feed, moving for 1-2 times every day, averagely moving for 20-30 minutes each time, and controlling motion to be carried out before meals, wherein the compound feed is prepared from the following raw materials of corn, extruded soybeans, imported fish meal, bran, deep sea fish oil, bovine placenta powder, dry brewer's grains, calcium hydrophosphate, carbonized bamboo powder, compound vitamins for pigs, compound minerals for pigs and phytase; and when the thickness of backfat of the sows reaches 20-21 mm, starting mating, wherein the mating time is 3-4 days, the mating frequency is 2-4 times, and the sows freely drinkdrinking water special for mating in the mating process.

Description

technical field [0001] The invention relates to the technical field of Huo Shou black pig breeding, in particular to a breeding method for increasing the estrus rate of Huo Shou black pig sows. Background technique [0002] Huoshou black pig is medium-sized, leaning towards meat, with black hair, long waist, long and straight snout, particularly developed snout, thick and lean legs, good meat quality, thin muscle fibers, and The ability of fat deposition in the middle is strong, and the slices cut out are like red velvet rolled with white lace, with beautiful marble patterns, and have good reproductive performance. [0003] At present, Huoshou black pigs are raised in captivity, and are fed with spring grass, grain or rice stalks according to different birth seasons. If it is stocked in the forest area, it can grow a whole body of fat and fine meat. It is small in size, but it can accumulate fat, which is evenly distributed in the muscles, and it is particularly tender and ...

AI Technical Summary

Problems solved by technology

A prominent problem currently plaguing farmers is that the reproductive performance of Huo Shou black pigs is worse than that of other strains. In the existing Huo Shou black pig breeding process, black pig sows are prone to growth retardation and a significantly lower estrus rate, resulting in The increase of breeding costs, and the abuse of hormone drugs to increase the estrus rate will cause the problem of low immunity of sows, and the mortality rate will increase, which seriously affects the breeding efficiency
