Embodiment 1

[0056] A method for raising sows of special mountain pigs, comprising the following steps:

[0057] (1) Sows reach sexual maturity when they are 6-7 months old and weigh 75-80kg, and can participate in breeding when they reach physical maturity when they are 7-8 months old or weigh 80-90kg; 4-6 sows can be raised in each pen. , sows in the early pregnancy can be raised in limited pens or single pens, 2-4 sows can be raised in each pen in the middle of pregnancy, and 1-2 sows can be raised in each pen in the late pregnancy, from 7 days before delivery to the farrowing bed before weaning;

[0058] (2) To strengthen the feeding and management of sows, to meet the nutritional requirements during the empty pregnant period, early pregnancy, mid-gestational period, late pregnancy and lactation period, prepare diets for different periods, feed different feeds, and pay attention to the reasonableness of green roughage and concentrated feed collocation,

[0059] Pregnancy concentrate f...

Embodiment 2

[0075] It is basically the same as Example 1, except that: the concentrated feed for pregnancy: according to the percentage by weight, the concentrated feed for pregnancy: according to the percentage by weight, including 64% corn, 18.3% wheat bran, 6% soybean meal, 1.5% fish meal, 5.5% corn gluten meal, 2.5% puffed blood meal, 1.4% bone meal, 0.08% multi-vitamins, 0.12% multi-trace elements, 0.1% mold remover, 0.2% prebiotics, 0.3% salt ;

[0076] The weight ratio of green roughage to concentrated feed is as follows:

[0077] Empty pregnancy waiting period: the weight ratio of green roughage and concentrated feed is 33:67;

[0078] Pre-pregnancy and mid-term: the weight ratio of green roughage to concentrated feed is 25:75;

[0079] Late pregnancy: the weight ratio of green roughage to concentrated feed is 20:80;

[0080] Lactation period: The weight ratio of green roughage to concentrated feed is 14:86.

Embodiment 3

[0082] It is basically the same as Example 1, except that: the concentrated feed for pregnancy: according to the percentage by weight, the concentrated feed for pregnancy: according to the percentage by weight, including 63% of corn and 19.7% of wheat bran, 5.5% soybean meal, 1.8% fish meal, 5.25% corn gluten meal, 2.5% puffed blood meal, 1.3% bone meal, 0.12% multi-vitamins, 0.08% multi-trace elements, 0.1% mold remover, 0.3% prebiotics, 0.35% salt ;

[0083] The weight ratio of green roughage to concentrated feed is as follows:

[0084] Empty pregnancy waiting period: the weight ratio of green roughage and concentrated feed is 32:68;

[0085] Pre-pregnancy and mid-term: the weight ratio of green roughage to concentrated feed is 24:76;

[0086] Late pregnancy: the weight ratio of green roughage to concentrated feed is 19:82;

[0087] Lactation period: The weight ratio of green roughage to concentrated feed is 15:85.

Abstract

The invention relates to a sow feeding method of a special wild pig. The method comprises the following steps: (1) feeding sows to reach sexual maturity when the sows are 6-7 months old and are 75-80 kg weight and reach body maturity when the sows are 7-8 months old and 80-90 kg weight and mating the sows; feeding and mating 4-6 non-pregnant sows in each pigsty; feeding each sow at the first trimester of pregnancy in a limiting pigsty or in an independent pigsty, 2-4 sows at the mid trimester of pregnancy in each pigsty and 1-2 sows at the later trimester of pregnancy in each pigsty, and feeding the sows on obstetric tables from 7 days before parturition to weaning; (2) reinforcing sow feeding management, meeting nutritional requirements in the non-pregnant to-be-mating period, the first trimester of pregnancy, the mid trimester of pregnancy, the later trimester of pregnancy and the suckling period, preparing daily rations for the different periods, feeding different feeds, and paying attention to rational matching of green and coarse fodders and concentrated feeds. According to the sow feeding method, the feed and the control for feeding are optimized, so that the sows rut quickly, the farrowing rate is high, normally 12-14 piglets are born by each sow, and the survival rate is over 90 percent.

Description

technical field [0001] The invention relates to a method for raising sows of special boar, belonging to the field of boar breeding. Background technique [0002] Wild boar, also known as wild boar, has a very wide distribution range. Wild boars in China are mainly distributed in the three northeastern provinces, Yunnan-Guizhou, Fujian, and Guangdong. On the one hand, the number of purebred wild boars has been drastically reduced due to factors such as human hunting and the sharp reduction of living environment space, and has been listed as an endangered species by many countries. However, purebred wild boars have slow growth, light weight, limited number of wild boars, thick meat, thick skin, poor meat taste, etc. It is not suitable for simple domestication and promotion, and wild boars are in estrus seasonally, with few litters, and are not easy to raise. . And people seek wild game and improve taste and the requirement for nutritional value is constantly increasing. [...
