Breeding management method of boar
Improving the activity and debugging of boars, a certain intensity of exercise is necessary for the physical and mental health of boars, which can increase their appetite, improve their physique, prevent boars from being too fat, ensure boars to be strong, and be conducive to future reproduction. Farmers should adhere to the fitness exercise of boars, which can be carried out in the cool morning and evening in summer and at noon in winter. Breeders should have an infectious effect with boars, touch them more and scrub their bodies, which is conducive to promoting blood circulation of boars' skin and reducing the probability of ectoparasites. Let boars start debugging in 6-7 months, let boars understand the breeding process and collect sperm every week. Feeding standard, the boar, controls the health of the boar. The standard requirement for breeding boars is neither fat nor thin. Feeding boars should make them healthy and sexually active. Overweight breeding boars will lead to low sexual desire or even complete loss of sexual desire, which is also because the concentrate is relatively single.
Most of them are energy feeds, with less protein and vitamins. Farmers should reduce energy feed, increase the proportion of green concentrate feed and strengthen exercise. It is also unacceptable that boars are too thin (lack of nutrition or over-breeding), poor semen quality and low semen volume. Farmers must immediately adjust the concentrate feed, improve the nutritional composition of boars, reduce the breeding frequency, and let boars slowly repair. Thoroughly test the immunity and semen of boars. Farmers should regularly carry out insect repellent work on breeding boars to remove internal parasites and external parasites. Generally, deworming should be carried out at least twice in autumn and spring, and immunization procedures should be completed before breeding. It is not suitable to deworm during the breeding period.
At the same time of debugging the reserve boar, farmers should conduct quality inspection on the boar semen. After 2-3 inspections, if the semen quality is still poor, it should be treated or replaced immediately, or left to pig farms for trial use as breeding pigs. But not suitable for breeding pigs. The management of boars should not be too frequent. If breeding or sperm collection is too frequent, it will cause the boar's constitution to be weak and cold, reduce its reproductive ability and even shorten its service life. Will prematurely replace 1-2 year old boars, usually twice a week. If it is an adult boar about 2 years old, it will be bred four times a week, although it won't take long for the boar to use it.
Farmers should do a good job in heatstroke prevention at high temperature. The suitable temperature for breeding boars is 18-20 degrees. Every time the temperature rises 1 degree in summer, the semen quality of boar will decrease obviously. Farmers generally use seepage cooling, cooling water curtain cooling, spraying cooling and other forms. In winter, the pigsty should be protected from freezing and warm, so as to reduce the occurrence of diseases and the consumption of concentrated feed. Farmers should avoid fighting between boars. It is best to prevent boars from meeting each other. If there are too many boars, an annular runway can be built in the pig infield, so that two boars can move at the same time without disputes. The focus of boar management is to introduce various management countermeasures about boars in detail. In order to ensure the economic benefits of pig farms, we must do a good job in the management of boars.
