Method for raising special fragrant pigs

Abstract

The invention mainly relates to the technical field of new pig variety raising, and discloses a method for raising special fragrant pigs. The method includes primary hybridization, back-crossing, in-herd mating and piglet management. The method has the advantages that the special fragrant pigs raised by the aid of the method are excellent and stable in character and high in adaptability and farrowing quantity, can grow fast, can get mature early and have thin skin and tender pork, the pork is fat but not greasy and is fragrant and delicious, the carcass lean percentage can reach 62.4%, and characters of Luchuan pigs and Bama miniature pigs can be obviously optimized; hybridization is carried out on Luchuan sow and Bama miniature boars at first, and accordingly the character of high reproductive capacity of the Luchuan sow can be kept; back-crossing is carried out on first filial generation and female parents or male parents, and accordingly the shortcomings of the Luchuan pigs can be overcome; in-herd mating is carried out on second filial generation to obtain third filial generation with excellent and stable characters; feeding management is carried out on the third filial generation, the temperatures and the humidity of pigsties are regulated, accordingly, growth and development of piglets can be promoted, the piglets can be bred by means of grazing when the pigs are 10 daysold, the environmental adaptability of the piglets can be improved, the coarse fodder intake of the piglets can be increased, the pork is fragrant and delicious, and the breeding cost can be reduced.

Description

technical field [0001] The invention mainly relates to the technical field of breeding new pig varieties, in particular to a method for breeding special fragrant pigs. Background technique [0002] Luchuan pig, named after its origin in Luchuan County in the southeast of Guangxi, is one of the eight local excellent breeds in the country. High fecundity, with an average litter of more than 12 piglets, good motherhood, stable heredity, but also has its disadvantages, mainly short body, sunken back and waist, large abdomen, plump buttocks, slow growth rate, and high breeding costs. Its skin is thin, the meat is tender, crisp but not greasy, and the carcass lean meat rate is 36.7%. It can be processed into crispy suckling pig, sausage, skinless streaky bacon, etc. Luchuan pig is the county treasure of Luchuan, and Luchuan piglets are gradually sold To all parts of the country, but also exported to Vietnam. [0003] Bama Fragrant Pig, originated in Bama Yao Autonomous County, G...

Problems solved by technology

[0004] Crossbreeding is one of the common methods for breeding new animal varieties. Selecting the appropriate male parent and female parent, and selecting the excellent traits of the male parent and female parent, will result in the desired new breed. Luchuan pig and Bamaxiang pig are two Both of these excellent breeds have their own advantages and disadvantages. Crossbreeding the two breeds can avoid the disadvantages of Luchuan pigs, such as large belly mopping the floor, slow growth, low breeding remuneration, and small litter size of Bamaxiang pigs. However, at present There is no report of crossing these two varieties. Patent document CN 104904659 A discloses a hybrid breeding method for wild fragrant pigs. It uses pure wild boars as male parents, Tiandong Qilixiang sows, Bamaxiang sows, Huanjiang Xiang sows and local Tuxiang sows were used as female parents, and three pure wild boars were crossed with the same Xiang sow on the 1st, 2nd, and 3rd days respectively, and then wild Xiang pigs were obtained. The boar and fragrant sow are only crossed once, and the traits of the first generation of hybrids are not necessarily the desired target traits, and the traits of the offspring are not stable, and it is easy to produce other unwanted traits when mating with the offspring. The pure wild boar is obtained, and the patent literature is to use wild boars and fragrant sows to crossbreed, and the resulting shape is only related to wild boars and fragrant pigs
