1. Choose hybrid lamb fattening Choosing rams of good foreign meat breeds with good meat production performance, such as hornless Dorset rams, Lincoln rams, German Merino rams, etc., to crossbred with multiple high-yielding small-tail sheep ewes, resulting in Crossbreeding lambs can significantly improve the meat production performance of Small Tail Han sheep. According to experiments, weaned castrated lambs of 3 months old weaned (Shornless Dorset sheep) were house-fed and fed mainly with grass and corn silage, supplemented with appropriate ingredients and fattened for 5 months before slaughter. The live weight reached 40.96 kg, the carcass weight was 20 kg, the slaughter rate was 52.22%, the net meat weight was 15.66 kg, and the net meat rate was 38.22%. 2. Early feeding One week after birth, the lamb can begin to give some fresh grass, leaves and soft grass, etc. The grass can also be tied into small bundles and hung on a shelf that can be eaten by lambs in the high places, so that lambs can freely eat. In order to allow the lambs to eat as soon as possible, the fried condiments can be initially served in pots to induce the lambs to feed through the scent. You can also apply the powder to the lamb's mouth and allow it to grind repeatedly. When it smells sweet and tastes sweet, it will rush to eat. In order to ensure that the lamb can eat, you can set a lamb bar on the side of the sheep's collar and set a feed slot in the bar to allow lambs to come and go freely and eat at any time. The fine material must be ground, the proportion should be appropriate, and the nutritional value should be comprehensive. Especially at the age of 50 days, it is the time for the lamb to shift from sucking to graze. Since the amount of feeding is increased and the feed intake is increased, attention should be paid to the diet. Full price, high levels of protein and energy nutrition. Usually two-week-old lamb, can eat 50 to 70 grams of concentrate every day, 3 to 4 weeks old can eat 100 to 150 grams, can eat more than 200 grams before weaning; 1 month old lamb can eat 100 grams of hay a day , 2 months old 400 grams, 3 months old 700 grams, 4 months old 1000 grams. 3. Early weaning Abroad is generally weaned at 45 to 50 days of age. Domestically, 2 months of early weaning are used for fattening. Lamb development is relatively uniform, and weaning can be used once. If the development is strong or weak, batch weaning can be used. That is, the strong lamb is weaned first, and the lean lamb continues to breastfeed. The weaning time can be appropriately extended. After weaning, the lamb is left in the original shed. The ewes are locked in the farther sheep house to prevent the lamb from reading the mother and affecting the feeding. Lambs should be gradually weaned so that they have a process of adaptation. Generally it is appropriate to complete the process after 6-8 days. At the beginning of weaning, only the mother and child were suckled together twice a day in the morning and evening, and then changed to suckling once, and finally weaned completely. Gradually weaning can prevent the occurrence of mastitis in ewe, which is also conducive to the healthy development of lambs. When rearing large groups, lambs of similar age and size should be weaned together, which is beneficial to the recovery of the group ewe during the same period. The next time the estrus is neatly groomed, the lambs are concentrated, and the sheep is managed in a unified manner. 4. Timely castration and regular deworming Goats are known as sheep. Lambs used for fattening should generally be cast off within 1 to 3 weeks. At this time, castration is beneficial to improving the quality of meat, making the meat tender, reducing the smell, making the sheep temperate, easy to manage, saving feed, easy fattening, It can also prevent random mating. It's best to choose to go on a sunny day in the morning. There are three methods of castration, including forceps forceps, surgery and ligation, which can be selected according to specific conditions. Lambs for fattening should be dewormed once after weaning and during autumn to prevent parasites in the body and affect the fattening effect. Commonly used de-worming drugs are: Nitrochlorophenol, 4 mg per kilogram of body weight orally; or sulfur didichlorophenol per kilogram of body weight 35 to 75 mg orally; or albendazole per kilogram of body weight 2.5 to 3 mg orally, to be cautious ,Safe and effective. 5. Fine feeding The traditional and extensive feeding method is the way of feeding fine tug fattening, making full use of crop stems oranges, hay and agricultural by-products. The crude and fine feeds can be reasonably matched, and the concentrate can account for 45% to 60% of the diet. For: corn 83%, bean cake (peanut cake) 15%, limestone powder 1.4%, salt 0.5%, vitamins and trace elements 0.1%, if no bean cake, peanut cake can be replaced by 10% of fish meal, while the proportion of corn is transferred to 88%, roughage can be used hay, cornstarch powder and so on. And establish a normal living system, regularly feeding sheep, drinking water, drinking water to supply adequate, good water quality, winter and spring season, the water temperature generally can not be less than 20 °C, and maintain clean and hygienic. 6. Use of weighting agents and application of rumen-modulating additives 6.1 Using weighting agents The "zebrazein" pellets were implanted on the subcutaneous cartilage of the sheep's ear. Without special care, the sheep could increase the weight gain rate by 15% to 20% within 2 months, and the feed conversion rate was increased by about 10%. One lamb per sheep, the efficacy lasted for 60 days, can be repeatedly implanted, cumulative weight gain effect. Alternatively, use monensin sodium 25 to 30 mg per kilogram diet. The initial amount of feed can be lower, then gradually increase to the required amount. The application of monensin sodium can increase the daily gain of lambs by more than 30%. 6.2 Application Rumen Control Additives In order to reduce abnormal fermentation acidity in the rumen and prevent chronic acidosis, it is advisable to feed less or not oversaturated silage when using high-precision diets to grow lambs, and to use vitamins (or VA) to satisfy vitamins. The needs of the same time in their diet by adding rumen regulation additives, such as sodium bicarbonate and magnesium oxide and other buffer compounds. Generally, the ratio of sodium bicarbonate and magnesium oxide is 2:1, and the amount of sodium carbonate is 2% to 1.4% (fine amount). 6.3 Application of urea phosphate Each day, about 10 grams of urea phosphate was added to each sheep, and the average diet increased by 26.7%. 7. Timely slaughter Small tailed sheep generally have large early growth intensity, and later growth slows down. If meat lambs are slaughtered after being raised to over 1 year of age, they will not only have high feeding costs, but also have thicker fat, higher odor, and tougher meat. Therefore, the lamb fattening period is best when it is 5-6 months old.
Health Monitor (Health Care Monitor) is based on the principle of pulse pressure method, and based on the established theory, the model is divided into compartments, and a series of calculation formulas are deduced by linear correlation algorithm.
