Technical Field

The invention relates to the field of livestock breeding, in particular to a method for breeding a Changbai boar.

Background

The breeding of the backup boars is the basis of the expanded reproduction of the pig farm, and only the superior backup boars are bred to construct the superior production swinery, so that the continuous development of the pig farm is ensured. The estrus of the reserve boar is a key index of the reserve boar group, the replacement boar is low in breeding success rate due to improper nutrition and feeding schemes, and is eliminated due to no estrus, so that great loss is brought to a pig farm. The modern scientific pig raising mode has higher requirements on mineral elements and vitamins than fattening pigs in the later stage, so that the fattening pig feed cannot be used for feeding replacement pigs, and special feed for the replacement pigs is required. At present, farms and feed enterprises also recognize the influence of providing special feed for replacement pigs on the health and oestrus of the replacement pigs, and gradually develop special feed for the replacement pigs. But the level of the special feed is lower at present, and a systematic scientific process is not formed in the feeding of replacement pigs;

changbai pigs are native to Denmark and are a famous lean type pig breed in the world. Its advantages are high litter size, quick growth and development, saving feed, high lean meat percentage, poor stress resistance and high nutritive requirement. The pig is introduced from the first Sweden in 1964 in China, and has strains of American, English, French, Belgium and New Dan in China. The long white pig is usually used as the first male parent or the first male parent of the ternary hybrid (Du's growing up) pig in production. In the existing various lines of the Changbai pigs, the filial generation of the Mei line and the Xindan line has high growth speed and high feed reward, and the filial generation of the Belgium line has better body type and high lean meat percentage. At present, the Changbai pigs are cultivated in large quantities in China. Therefore, a better method for breeding the long and white boars is found, and the method has great significance for the popularization of the long and white boars.

Disclosure of Invention

The invention aims to provide a method for breeding replacement boars of the Changbai boars, which can effectively improve the physique of the replacement boars, enhance the oestrus rate and improve the breeding success rate of the replacement boars of the Changbai boars.

The method for raising the boars of the long and white pigs comprises the following steps:

the following feeds were given: 400-600 parts of sweet potato vine, 600-700 parts of corn, 50-100 parts of wheat bran, 200-300 parts of bean pulp, 20-50 parts of fish meal, 0.1-0.3 part of vitamin, 1-2 parts of kudzu root extract, 1-2 parts of rhizoma drynariae extract, 1-2 parts of pumpkin, 0.1-0.2 part of genistein, 1-4 parts of fructose and 1-5 parts of glucose; allowing it to be taken freely; the following extracts made from the plant materials were administered periodically every month for a period of one week: 5-20 parts of poria cocos, 5-10 parts of astragalus membranaceus, 1-3 parts of fennel and 1-5 parts of corydalis saxicola.

The extraction method of the plant raw materials comprises the following steps:

taking 5-20 parts by weight of poria cocos, 5-10 parts by weight of astragalus membranaceus and 1-3 parts by weight of fennel, adding water, decocting for 1-3 times, 1-3 hours each time, adding water 6-12 times of the total weight of the 3 raw materials each time, combining decoction, filtering, and concentrating filtrate to 2-5 times of the total weight of the 3 raw materials to obtain an extracting solution 1;

soaking 1-5 parts by weight of corydalis saxicola bunting in 50% ethanol as a solvent for 24-36 hours, percolating at a speed of 0.1-0.5% of corydalis saxicola bunting weight per minute, collecting 4-10 parts by weight of percolate, reducing the ethanol content to 5-10%, and mixing with the extract 1 to obtain the corydalis saxicola bunting.

The vitamins are prepared by mixing vitamin A, vitamin D3, vitamin E, vitamin K3, vitamin B12 and vitamin C.

The vitamins comprise the following components in parts by weight: vitamin A: vitamin D3: vitamin E: vitamin K3; vitamin B12: vitamin C = 1.5: 1:1.2: 1.2:1.

Through a plurality of practical tests, a plurality of formulas are screened, the feed additive which is suitable for growth, development and physiological characteristics of the replacement boars of the long and white pigs and can make up for the defects of the special feed for the replacement boars of the long and white pigs is found, the ovary of the replacement boars of the long and white pigs is induced to secrete the estrus hormone by using the plant extraction with unique proportion and the combination proportion of the flavochrome, and the matching of monosaccharide, fructose and glucose with a certain proportion is used for promoting ovulation and supplementing the energy of the boars, so that the physique of the replacement boars of the long and white pigs is effectively improved, the breeding rate of the boars is effectively improved, and the breeding cost is effectively reduced.
