Boar artificial insemination three-in-one feeding method and device thereof

Abstract

The invention discloses a boar artificial insemination three-in-one feeding method and a device thereof; the method comprises the following steps: A. a feeding method: breading boar artificial insemination three-in-one feeding method is adopted; B. construction process and material selection: insulating heat and keeping warm of two extremely harsh environmental temperatures in summer and in winterare respectively solved; and C. microclimate environment control in summer: a sub-pressure pumping and a wet pad cooling system are adopted so as to control the temperature in the workshop in a suitable range, therefore the breeding boar can have a safe life in summer. A laboratory is connected with a semen collection room which is connected with a boar stall; a heating pipe is arranged under thefloor of the boar stall; an unassisted exhaust fan is connected above the roof; the boar stall is connected with a fence door; a southern wall and a northern wall of the semen collection room are connected with a window which is connected with the mounting position of the wet pad; the end of the heating pipe is connected with an overall water inlet which is connected with a booster pump; and thebooster pump is connected with a non-pressure boiler. The invention has the advantages of convenient management and closely links three processes of breeding boar feeding, semen collecting and inspecting and sub-packaging, thereby improving the efficiency of the feeding and the artificial insemination.

Description

Technical field [0001] The invention belongs to the technical field of environmental engineering for large-scale breeding of live pigs, and specifically relates to a trinity breeding method of efficient breeding and artificial insemination of breeding boars, and specifically relates to a trinity breeding method for artificial insemination of boars, which is suitable for original breeding pig farms, Expand the construction of breeding pig farms, large-scale pig farms and professional artificial insemination stations. Background technique [0002] For a long time, the suitable living environment and breeding value of breeding boars have been highly valued by production practices. Especially lean breeding pigs have increased meat production due to high-intensity artificial selection, and improved daily gain and feed conversion efficiency. It also generally brings about a decline in resistance and fertility. The study found that: due to the incompatibility between multiple animal tr...

AI Technical Summary

Problems solved by technology

The study found that: due to the incompatibility between multiple traits of animals, the implementation of artificial selection can improve the production performance on the one hand, and on the other hand lead to a decrease in the viability of high-yield male animals, and they are more sensitive to "stress" in high-temperature and low-temperature environments

When the natural temperature reaches above 34°C, 25-30% of the breeding boars raised in large-scale pig farms will have reproductive dysfunction, such as: reduced feed intake, accompanied by mental restlessness, shortness of breath, and muscle tremors. The length and width of the testes expand respectively 3cm, after that, the body temperature rises by 0.5-1.0°C, and the breath increases by 15-16 times per minute, especially the low libido, impulse suppression, low ejaculation volume, low sperm density, increased number of deformed sperm and dead sperm, and decreased vitality, causing sows The conception rate is lower than 65% (normally above 90%). Even if this high temperature climate is a short-term impact, it is difficult to recover 3 to 5 months after this phenomenon occurs, and even forces the elimination of "stressed boars", which seriously affects the reproductive effect

[0003] Studies have shown that it is difficult to solve the physiological recovery of low semen quality (such as semen volume, sperm density and motility, fertilization rate, litter size, etc.) from the selection of drugs for the conditioned (high temperature environment) reproductive dysfunction of boars. Accelerate the degradation of reproductive function of breeding pigs and shorten the service life
