Scientific breeding and rational use of Boer goat rams play a decisive role in the development and quality of the entire offspring herd.
There are basically two kinds of sexual performance of rams and scientific utilization of the breeding methods of Boer goats, namely natural mating and artificial insemination. In order to improve the speed of breeding, more methods of artificial insemination are used.
Boer goats have less libido than other goats, but rams have an earlier libido performance. There are chase and crawling movements from 1 to 3 months of age, but they actually have mating behavior and ejaculation ability, usually around 5 months of age, to 6 The age of sexual organs is basically mature, but physical development has not been completed, so it is not appropriate to breed. According to the individual development status, about 10 months of age can be appropriate amount of sperm extraction or mating. When the rams begin to collect sperm, it is best not to exceed two times a week. 1 year old can be formally invested in sperm production, generally 4 times weekly sperm extraction. Feeding conditions are good, rams have good constitution, and the number of sperm pickings per week can be appropriately increased. Ejaculation volume, sperm density, and sperm survival rate differ depending on age, physical condition, and sperm collection method. The amount of sperm extraction is relatively straightforward, generally averaging about 1 ml per time, but the sperm density and sperm motility need to be measured by relevant instruments before they can be known. Therefore, semen should be used scientifically and reasonably when artificially inseminated. Once diluted, the semen can be used for insemination in dozens of sheep.
The scientific breeding of male rams should be such that the male ram is strong in physique, moderate in sensation, energetic, strong in libido, and has good semen quality. It is necessary to strengthen scientific feeding and management so as to increase the utilization rate of the ram and extend its useful life. .
The breeding of rams requires a high nutritional value of feed, a sufficient amount of high-quality protein, vitamins and inorganic salts, etc., and easy to digest, good palatability. In the non-breeding period, high quality hay and a small amount of fresh green succulent feed are fed regularly twice a day, while each adult ram feeds 0.5 kg of full-price compound feed daily. During the fertilization period, the total supply of feed is about 0.8 kg per day. It is best to feed 1-2 raw eggs. The rams should be raised in a single lap, and they should be fed mainly. The Boer goats like to dry, and it is best to use wood to make slatted floor beds. Rams spend 4-6 hours a day grazing combined with exercise, allowing them to eat freely. Exercise or grazing can not only maintain a good body shape, enhance disease resistance, but also enhance sexual desire and increase sperm motility. If the broiler libido and ejaculate amount are normal, but the success rate of the fertilized mother is low, the sperm survival rate and the quality of the semen are mostly poor, and the feed containing selenium, zinc and other trace elements may be appropriately increased. The supplement of concentrate feed can be determined according to the body condition of the ram, which not only allows the ram to have sufficient energy, but also cannot feed too thin or too fat. Roughage should be properly controlled in order to keep the rams in good shape. Always observe the health status of the sheep and timely diagnose and treat the disease.
