Abstract
The invention discloses a method for cultivating a robust pig specialized strain by means of yulan black pigs. The method comprises the steps of crossing high-quality yulan black boars different in consanguinity with yulan black sows with excellent maternity, then conducting crossing fixation, conducting crossing with hampshire boars to obtain parent generation sows, and taking red duroc pigs as parent generation boars to obtain commercial pigs. Compared with the prior art, the method has the advantages that yulan black pigs are used as the leading variety for hybrid breeding, and excellent reproductive performance of yulan black pigs is better stabilized through crossing fixation; the fertility of yulan black pigs is further improved through crossing with hampshire pigs, and pork quality and robustness are improved; finally, through crossing with high-quality red duroc pigs, the commercial pigs with high stress resistance, high robustness, high growth speed, high disease resistance and high-quality meat are obtained. The commercial pigs are suitable for being bred in the south of China, and economic benefits can be increased.
Description
Technical field
The invention belongs to technical field of agricultural breeding, a kind of method being specifically related to breed system utilizing the black pig of Magnolia denudata to cultivate healthy and strong pig.
Background technology
Red duroc be well-proportioned compact, extremity are sturdy, body body is deep and broad, muscular, head is of moderate size, and mouth cylinder is short directly, ear median size, have sharp ears is slightly bent, and chest breadth is deep, and back of the body waist is the most domed, emerge straight, strong-limbed, there is the advantages such as fast growth, feed conversion rate height, strong stress resistance.
The black pig of Magnolia denudata is with winter rape, wild herbs, Rhizoma Dioscoreae esculentae and agricultural byproducts and water from washing rice make main feedstuff, it is good that the black pig of Magnolia denudata raised has build, disease resistance is strong, lean meat is brown red, Adeps Sus domestica brilliant white, the features such as maternal instinct is good, the speed of growth is due to traditional black pig, lean meat percentage is high, rich in multi mineral prime element and unsaturated fatty acid, the sow of 9 pairs of nipples reaches 76.4%, sow can carry out copulation in the sexual maturity of 6 monthly ages, average bearing capacity the first-born i.e. can reach 10.26, two tires reach 11.83, more than triplet and triplet reach 14.22, utilization rate can reach about 10 years, but its uniformity is poor, the most suitably promoted.
Summary of the invention
It is an object of the invention to for existing problem, it is provided that a kind of method of breed system utilizing the black pig of Magnolia denudata to cultivate healthy and strong pig.
The present invention is achieved by the following technical solutions: a kind of method of breed system utilizing the black pig of Magnolia denudata to cultivate healthy and strong pig, comprises the following steps:
(1) select the most consanguine high-quality Magnolia denudata black pig boar and there is the Magnolia denudata black pig sow hybridization of outstanding maternal instinct, the filial generation that 6 monthly ages are the most ill is selected in its filial generation, traversed by is fixed, and cultivates build high-quality hybrid offspring uniform, stable performance maternal as breed system；
Wherein, during the feeding of the black pig of Magnolia denudata and filial generation thereof, when its body weight grows to 3 kilograms, wild herbs weight ratio in its day feedstuff is 10-15%；When its body weight grows to 5 kilograms, wild herbs weight ratio in its day feedstuff is 20-25%；When its body weight grow to 10 kilograms and above time, wild herbs weight ratio in its day feedstuff is 30-50%；
(2) using breed system female parent to hybridize with Hampshire boar, hybridization obtains breed system father and mother godmother pig；
(3) with red duroc as father and mother for boar, hybridize with above-mentioned gained father and mother godmother pig, it is thus achieved that breed system market pig.
As further improvement of these options, described wild herbs refer to the combination of any one or more in winter rape, Herba Oenanthes Javanicae, wild bamboo sprout, many toothed lady fern and Herba Lactucae Indicae.
As further improvement of these options, the feature of described high-quality Magnolia denudata black pig boar is: head is of moderate size, face nick, and ear is the most sagging, and across back is put down, and extremity are solid；The feature of the Magnolia denudata black pig sow with outstanding maternal instinct is: has 9 pairs of nipples, reaches more than 12 at the average bearing capacity of the first-born；Build is uniform, the feature of the high-quality hybrid offspring of stable performance is: appearance traits is basically identical, physically fit, and reproductive capacity is strong, and disease resistance is good, and meat is excellent.
As further improvement of these options, the feature of described Hampshire boar is: head is of moderate size, and face is straight, and ear is upwards upright, and middle body is wider, and the back of the body has a large waist short, and eye muscle area is relatively big, and adult weight is bigger.
As further improvement of these options, the feature of described father and mother godmother pig is: head is of moderate size, and ear is the most vertical, and middle body is wider, and trunk is long, and eye muscle area is big, and lean meat percentage is high, and meat is excellent, and reproductive capacity is strong, and disease resistance is good.
As further improvement of these options, the feature of described market pig is: being well-proportioned compact, head is of moderate size, and hair color mostly is black, having a little rufous hair, trunk is long, and extremity are sturdy, muscular, ear bigger than normal half stands, and eye muscle area is big, fast growth, strong stress resistance.
As further improvement of these options, the average daily gain of described market pig reaches more than 800g；Eye muscle area cross-sectional area is about 34 square centimeters.
The present invention has the advantage that compared to existing technology with the black pig of Magnolia denudata as principal item, carries out supporting hybridization, by the most fixing, the outstanding reproductive performance making the black pig of Magnolia denudata is more stable, then by further enhancing its fertility with Hampshire hybridization, improving meat quality and healthy and strong build, last and high-quality red duroc kind draws strong stress resistance, physically fit, fast growth, disease resistance is strong, the market pig that meat quality is high, it is suitable for cultivating at south China, increases economic benefit.
