Problems solved by technology

[0006] At present, the commonly used methods to improve the fertility of boars basically only consider nutritional factors or feeding methods, and have limited effect on improving the fertility of boars. Therefore, if a more reasonable and scientific method for boars can be formulated Feeding management methods are very necessary

preparation example 1

[0063] This preparation example prepares a special feed for boars, and its formula contains in parts by weight: 50 parts of corn, 20 parts of soybean meal, 0.4 parts of salt, 25 parts of fermented composite fibers, 5 parts of composite fat, 3 parts of calcium supplements, trace amounts 1 part of elemental premix, 1 part of vitamin premix.

[0064] The fermented composite fiber is prepared by the following preparation method: the defatted rice bran, oat bran, sugar beet dregs, soybean hulls and pea hulls in a mass ratio of 2:1:1:2:1 are pulverized and mixed, mixed with 5% composite probiotics ( Bacillus subtilis powder and lactic acid bacteria powder with a mass ratio of 2:1 are mixed, anaerobic fermentation is carried out at 32 ° C, the fermentation moisture is adjusted to 50% with distilled water, the fermentation is 72 hours, and the moisture is dried.

[0065] The compound fat is composed of 10 parts of linseed oil, 10 parts of perilla oil, 10 parts of safflower oil, 5 part...

preparation example 2

[0070] This preparation example prepares a special feed for boars, and its formula contains in parts by weight: 55 parts of corn, 15 parts of soybean meal, 0.4 parts of salt, 27 parts of fermented composite fibers, 3 parts of composite fat, 2 parts of calcium supplements, trace amount 2 parts of element premix and 1 part of vitamin premix.

[0071] The fermented composite fiber is prepared by the following preparation method: the mass ratio of defatted rice bran, oat bran, sugar beet dregs, soybean hulls and pea hulls in a mass ratio of 1:2:1:2:1 is pulverized and mixed, mixed with 3% composite probiotics ( Bacillus subtilis powder and lactic acid bacteria powder with a mass ratio of 2:1 are mixed, anaerobic fermentation is carried out at 35 ° C, the fermentation moisture is adjusted to 45% with distilled water, fermentation is performed for 70 hours, and the moisture is dried.

[0072] The compound fat is composed of 10 parts of linseed oil, 20 parts of perilla oil, 5 parts o...

preparation example 3-7

[0077] This preparation example prepares five kinds of boar-specific feeds. The difference between its formula and preparation example 1 is that the fermentation raw materials only contain defatted rice bran, oat bran, sugar beet dregs, soybean hulls and pea hulls respectively when preparing fermented fibers. Other raw materials and contents remain unchanged. The preparation method is the same as that of Preparation Example 1.

Abstract

The invention relates to a prevention and control method for promoting reproduction of boars. The method for preventing and controlling reproduction of boars comprises: feeding a special feed for boars: the special feed for boars includes fermented composite fibers, composite fat and base material. and additives; feeding mode: breeding boars are fed ad libitum to a body weight of 80-100kg and then reared under restrictions; control the temperature of the pig house to 18-25°C and the humidity to 50-60%. The method for preventing and controlling breeding of boars involved in the present invention adopts different feeding modes in different growth stages according to the physiological characteristics and nutritional needs of boars, and organically analyzes the nutritional composition, feeding mode and environmental factors of the feed. Combined, comprehensively prevent and control the breeding process of breeding boars, effectively improve their fertility, and overcome the current lack of sexual desire, loss of libido, abnormal semen, etc. Conditions that reduce the reproductive performance of breeding boars.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a method for preventing and controlling breeding of boars. Background technique [0002] The breeding boar is the core of the pig farm. The reproductive performance of the breeding boar directly affects the litter size, litter rate and fecundity of the sow, thus affecting the production performance and economic benefits of the pig farm. Appropriate nutrient supply and scientific feeding Feed management is required for the current intensive boar production. [0003] Poor semen quality is a major cause of boar culling. According to statistics, 18.4%-26.4% of boars are culled each year due to poor semen quality. As an important influencing factor, nutrition is directly related to boar reproductive performance and breeding years. However, at present, the nutritional needs and feeding management of boars have not been paid enough attention. Many pig farms use pregnant ...
