Ask for goat breeding techniques?

(agricultural get Rich Network) ask for goat breeding technology? Q: when is the best time for sheep to breed? Answer: September and October are good seasons for sheep to breed, because the pregnancy period of goats is 152 days and that of sheep is 150 days. If ewes get pregnant in September or October, they can give birth in February or March of the following year. Its advantages: first, the climate is getting warmer, the grass begins to grow out, and the natural environment is very beneficial to the lactation of ewes and ensuring the survival of lambs. Second, the weight of female lambs born in early spring can reach more than 35 kg from 8 to 9 months of age, and can be mated from October to December. Third, according to its physiological law, ewes enter the peak period of lactation in the third month after delivery. Lambing in early spring can ensure that ewes eat Robinia pseudoacacia leaves and tender grass during the peak period of lactation, which can increase the milk yield and economic benefits of female goats. Q: what preparations should be done for sheep before mating? Answer: the breeding and management of rams and ewes should be strengthened 1-2 months before the peak breeding season. Grazing sheep should seize the favorable opportunity of forage grass seed and rich in nutrition in autumn to prolong the grazing time, let the sheep eat well, and supplement the concentrate feed. The house-feeding sheep should increase the concentrate feed by 30% to 50% than usual, and the breeding ram should be fed 250 grams of carrots every day to make the sheep fat and strong, the ewe in estrus normal and the ram with high sexual desire, so as to improve the conception rate of mating. At the same time, the breeding station (point) should prepare artificial insemination equipment and strictly disinfect it to meet the breeding. Q: how to make full use of heterosis? Answer: using two breeds to cross, such as using Boer goats to match the offspring of local ewes, they grow and develop faster, weigh higher than local goats, have stronger disease resistance than Boer goats, have the advantages of two parents, and some advantages even exceed those of their parents. this phenomenon is called "heterosis". The crossbred lambs (half male and half female) of 200 Boer goats were measured in a sheep farm. The average birth weight was 3.1 kg and the weight at the age of 4 months was 26.1 kg, which increased by 31.4% and 74.1% respectively compared with local sheep. The survival rate of lambs reached 100%, which was 5% higher than that of Boer goats. According to the identification of relevant experts, the average annual milk yield of the improved 1Y3 generation of Saaneng dairy goats with local dairy goats is 639 kg, which is 107% higher than that of local dairy goats. Fattening rams increase feed remuneration (meat and skin in exchange for forage) by 57% compared with local rams. Therefore, it is necessary to breed sheep according to the requirements of economic types, and select breeds in a planned way to avoid inbreeding so as to increase economic benefits. -- not bad, top
