How to deal with low reproductive rates in meat sheep? Practical solutions shared
Feeding fishmeal to meat sheep can improve the reproductive rate. Feed-grade fishmeal contains 90% dry matter, of which about 15% is ash, about 65% is crude protein (about 60% is digestible protein that can be directly used by animals), and about 7% is minerals such as crocodile [sic] and phosphorus. It is a good animal-based feed. In order to improve the breeding value of stud rams, further improve the efficiency of sheep artificial insemination, and explore ways to solve the source of protein feed, during the winter mating of 1972, at three mating points of the Heka Stud Sheep Farm, we trial-fed fishmeal to Xinjiang, Tsigai, Polwarth and crossbred rams bred on the farm, with good results. The feeding method is to sprinkle the fishmeal into the feed and mix it evenly. Fishmeal contains long-chain polyunsaturated fatty acids and is a good source of eicosapentaenoic acid and docosahexaenoic acid. Long-chain fatty acids have greater resistance to rumen bacteria. In addition to being rich in protein and more than 50% rumen-undegradable protein, which can increase milk yield and the protein percentage of cow's milk and sheep's milk, another important aspect of fishmeal is that it can inhibit the prostaglandin levels of cows and ewes. According to reports, 30 high-yielding ewes were fed diets with 0, 2.6, 5.2 and 7.8% fishmeal for a total of 42 days, and the results showed that inhibition of prostaglandins in ewes can improve embryo survival rate.</p><p></p><p>Supplementing more digestible undegradable protein in late pregnancy and early lactation can significantly increase peak milk yield and milk yield in the first 8 weeks of lactation. In most studies, milk composition increased somewhat, especially milk protein yield in early lactation. In addition, feeding more digestible undegradable protein may also increase appetite, and fishmeal is a good source of digestible undegradable protein.</p><p>Strengthen selection and mating</p><p>Selection of stud rams: select and breed rams from the offspring of ewes with high reproductive rates. They are required to have standard body shape and appearance, be robust, have well-developed testicles, and have obvious male characteristics, and through measures such as semen quality testing and progeny testing, discover and eliminate rams that do not meet the requirements.</p><p>Selection of ewes: select excellent individuals from the offspring of prolific ewes, and pay attention to their lactation and nursing performance. Prolific ewes can also be retained based on pedigree.</p><p>Use of prolific genes</p><p>Introducing prolific breeds and crossbreeding them with local breeds is the fastest, most effective and simplest method to improve the reproductive rate of meat sheep.</p><p>Control of breeding technology</p><p>Estrus control: 1. Early weaning of lambs is conducive to implementing the technology of two lambings per year. 2. Hormone treatment. First carry out early weaning of lambs, then treat ewes with progesterone for about 10 days, and after withdrawal inject them with gonadotropin (RMSG), which can induce estrus and ovulation. 3. Use the prostaglandin method. Several days after the end of estrus in ewes, infuse prostaglandin into the uterus or inject it intramuscularly, and the ewes will come into estrus 2 to 3 days after treatment.</p><p>Inducing twin and multiple births: 1. Supplementary feeding to stimulate estrus. Carry out supplementary feeding one month before mating to strengthen body condition and promote estrus. 2. Use twin-lamb stimulant or twinning agent. For the water-based product, inject 1 ml per sheep subcutaneously in the neck 5 weeks and 2 weeks before mating; for the oil-based product, inject 2 ml per sheep intramuscularly in the rump 2 weeks before mating.</p><p>Artificial insemination: adopt advanced insemination techniques to improve the conception rate.</p>
