Q: When is the most suitable time to breed sheep?
A: September and October are good seasons for breeding sheep, because the gestation period of goats is 152 days and that of sheep is 150 days. If ewes are bred and conceive in September or October, they can give birth to lambs in February or March of the following year. The advantages: First, the climate gradually becomes warmer and green grass begins to grow, and the natural environment is extremely favorable for ewes' milk secretion and for ensuring the survival of lambs. Second, ewe lambs born in early spring can reach a body weight of more than 35 kg by 8 to 9 months of age that same year, and can be bred again from October to December. Third, according to their physiological patterns, ewes enter the peak lactation period in the third month after giving birth. Lambing in early spring can ensure that ewes eat black locust leaves and tender green grass during the peak lactation period, which can increase the milk yield of female goats and increase economic returns.
Q: What preparatory work should be done before breeding sheep?
A: Strengthen the feeding and management of rams and ewes 1 to 2 months before the peak breeding season for sheep arrives. For grazing sheep, seize the favorable opportunity of autumn grass setting seed and being rich in nutrients to extend grazing time, let the sheep eat their fill and eat well, and supplement with concentrated feed. For housed sheep, increase concentrated feed by 30% to 50% compared with usual. Supplement breeding rams with 250 to 500 grams of carrots per day, so that the sheep are fat and strong, ewes come into estrus normally, and rams have high libido, thereby increasing the conception rate of breeding. At the same time, breeding stations (points) should prepare artificial insemination instruments, strictly disinfect them, and be ready for breeding.
Q: How can hybrid vigor be fully utilized?
A: Use two breeds for crossbreeding. For example, the offspring produced by mating Boer goat rams with local ewes grow and develop quickly, have higher body weight than local sheep, and have stronger disease resistance than Boer goats. They possess the advantages of both parents, and some advantages even exceed those of the parents. This phenomenon is called "hybrid vigor." A certain sheep farm measured 200 crossbred lambs produced by mating Boer goat rams with local sheep (half male and half female). The average birth weight was 3.1 kg, and the weight at 4 months of age was 26.1 kg, respectively 31.4% and 74.1% higher than local sheep, and the lamb survival rate reached 100%, 5% higher than that of Boer goats. According to appraisal by relevant experts, when Saanen dairy goat rams are mated with local dairy goats, the improved 1st to 3rd generation sheep produced have an average annual milk yield of 639 kg, an increase of 107% over local dairy goats, and the feed conversion of fattened rams is 57% higher than that of local rams (meat and hides obtained in exchange for forage). Therefore, sheep should be bred according to the requirements of the economic type, with planned selection and mating, and avoiding inbreeding, so as to increase economic returns.
