Slow growth of mutton sheep and its countermeasures

General meat goats, 12 months of age, but no more than 15 kilograms, the growth rate is very slow, mainly due to the first, due to inbreeding, physical deterioration; Second, do not pay attention to deworming, the parasite consumes a large number of sheep nutrition; Without scientific feed, it can not meet the nutritional needs of sheep growth. To improve the growth rate of sheep, the following technical measures must be taken: Do a good job of sheep's crossbreeding. High-quality, high-quality meat-producing hybrids should be introduced to local goats, and hybrid goats should be bred in large numbers for farming. Hybrid sheep have fast growth and strong resistance to diseases, laying the foundation for sheep's weight gain. Dispel parasites. Parasites not only consume large amounts of nutrients from sheep, but also secrete toxins that destroy the function of the sheep's digestive system, so they should be dewormed. With the highly effective anthelmintic drug levamisole, 8 mg/kg body weight, it is dissolved in warm water, and 5% aqueous solution is prepared for intramuscular injection, which can drive off various nematodes and roundworms in the sheep's body; at the same time, it is treated with dichlorophenol sulfate. Kg body weight 80 mg, add a little flour, 250 ml of water, fasting fed before feeding, or with albendazole, 15 g per kg of body weight water to gavage, can drive out the liver fluke and aphids to ensure a strong fattening period Physiological function. Scientific feed. Provide enough nutrients for fattening sheep, and all kinds of nutrients must be basically balanced so that sheep can grow quickly. Now introduce two practical feed formulations: (1) corn flour 45%, rice bran 20%, bean cake 10%, rapeseed flour 15%, wheat bran 10%, with hay, allowing them to eat freely; (2) Corn flour 50%, bean cake 15%, wheat bran 20%, rice bran 15%, with the hay, let it feed freely. The above two compound feeds can be optionally fed, and can be fed on the basis of green, hay, sweet potato vine leaves and corn stalks, supplemented with compound feed. After 3 months of age, the young goats weaned after weaning had a body weight of about 8 kilograms. In the case where good hay meets the demand, 150 g of the compound feed can be fed daily. With the increase of the age of the month, the daily feed can be increased to 200 grams. In order to supplement the deficiency of protein, urea can be added to the concentrate, and it can be fed from 3 to 4 grams in the initial stage, and then it can be increased to 5 to 6 grams. When fed with urea, it takes 5 days to allow the sheep to adapt and pay attention to the 1 after feeding. Hours do not drink water. The rapeseed cake must be cooked thoroughly and then fed to eliminate the toxic ingredients contained in the rapeseed cake. Add 4 to 5 grams of salt, 4 to 5 grams of bone meal or shell powder, and 8 grams of sodium sulfate. If you feed silage, add 5 grams of baking soda. According to this new technology, sheep can be fed goats with daily gains of 100 to 150 grams. By the age of 6 months, they can weigh 18 kg to 25 kg, which is more than double the growth rate compared to conventional rough-breeding methods. If you are feeding goats, the above formula feed can be fed 300 grams to 350 grams per day, urea can be added to 8 grams to 10 grams, and salt can be added to 8 grams to 10 grams. This method of feeding, breast milk secretion. Lambs practice grazing and eating from the age of 20 days, with daily gains of more than 100 grams. The above formulated feed is designed for caged sheep. For sheep that are grazing in the wild during the high season, the amount of supplemented concentrate can be reduced by 50%. However, no matter how much grass is sufficient, feeding at night is still necessary. Only in this way can fast growth of fattened sheep be guaranteed.
