Hi everyone, I am a lamb and breeding rams have sexual desire all year round. In the autumn breeding season, the sexual desire is strong, the semen quality is excellent, but the appetite decreases; in the winter and spring non-breeding seasons, the sexual desire is weakened and the appetite is gradually enhanced; in the summer, due to the hot weather, the sexual desire is cold, and the appetite is reduced. Therefore, the breeding of breeding rams, the non-breeding period is the basis, should strengthen the breeding, careful management, physical condition recovery, hair bright, energetic, in order to ensure that the breeding seasonal desire is exuberant, the use of long time; the breeding period is the key, should induce them to eat good palatability of high nutrient concentration of the diet, supplemental feeding protein feed, in order to better complete the breeding task.
Ram sexual reflexes are strong, must be regular mating or sperm collection, such as long-term tethering or breeding season, long-term non-use, there will be self-masturbation, temperament, top people and other vices, ram if breeding or excessive sperm collection, there will be low sperm density, less ejaculation, cold sexual desire, impotence and other phenomena, and will shorten its service life. Breeding rams bred with high-quality forage and sufficient exercise have strong reproductive performance, high breeding value and long utilization life under the condition of moderate breeding age and frequency of breeding.
After the first breeding of Boer goat ewes, ewes of all ages are adult ewes. Adult ewes are responsible for pregnancy, lactation and other tight breeding tasks, and should maintain good breeding and management conditions all year round in order to achieve the purpose of multiple births, multiple births, more liveliness and more strength. The feeding management of ewes in the middle of the year can be divided into three stages: the pre-breeding period, the gestation period and the lactation period.
For ewes that give birth to one litter per year, the pre-breeding period is the period from the time the lamb is weaned (3 months after delivery) to the time of mating and fertilization (7 months after childbirth). Ewe due to the previous stage of cap production and lactation, nutrition pay more, to this period, the general physical condition is thin, vertebrae, bone recommendation, loose joints and other bones have different degrees of exposure, and even hair removal phenomenon. The task of this period is to grasp the original rejuvenation as soon as possible, promote estrus, timely mating, and reserve sufficient nutrition for re-pregnancy.
Boer goat breeding effect is good. Due to the superior conditions of house feeding and enclosure, the supply of forage feed throughout the year is more balanced, coupled with the scientific and technological content of breeding management, the degree of intensification or semi-intensification is higher, so that the breeding of goats grows and develops well, the production performance is high, the proportion of special and first-class sheep is large, the group level is good, the reproduction rate, the turnover rate are higher, and the feed remuneration is remarkable.
Sheep farmers should clarify the direction and goal of sheep raising. According to natural conditions (such as grass feed, sheep barn, etc.), market demand (such as thoroughbred sheep, hybrid sheep, billet sheep, fresh semen and frozen semen, etc.), sustainability prediction and information reliability, the main direction and goal of raising Er goats in a period of time are determined. We'll see you in the next issue.
