1. The crossbreeding of sheep should involve the introduction of good-quality sheep breeds with good meat performance and local goats, and multiply breeding hybrid goats for farming. Hybrid sheep have fast growth and strong resistance to diseases, laying the foundation for sheep's weight gain.
Second, dispelling parasite parasites not only consumes a lot of sheep's nutrition, but also secretes toxins and destroys the function of the sheep's digestive system. Therefore, it should be dewormed. With the highly effective anthelmintic drug levamisole, 8 mg/kg body weight was dissolved in water and mixed into a 5% aqueous solution for intramuscular injection, which can drive off various nematodes and roundworms in the sheep; at the same time, dichlorophenol sulfate was used. Kg 80 mg body weight, add a little flour, water 250 ml, fasting fed before feeding, or with albendazole, watered at 15 mg per kilogram of body weight, can drive out liver flukes and aphids to ensure a strong fattening period Physiological function.
Third, scientifically formulated feeds provide sufficient nutrition 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) 45% of corn flour, 20% of rice bran, 10% of bean cake, 15% of rapeseed meal, and 10% of wheat bran, with the hay, allowing them to freely feed;
(2) 50% of corn flour, 15% of bean cake, 20% of wheat bran, and 15% of rice bran, with the hay, allowing them to 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. Young goats aged 3 months after weaning have a body weight of about 8 kg. 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 3 to 4 grams at the initial stage, and then it can be increased to 5 to 6 grams. When fed with urea, it takes 5 days for the sheep to adapt and pay attention to 1 hour after feeding. Drinking 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 in the feed, add 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 6 months of age, the weight of the hybrid goats can reach 18 to 25 kilograms. Compared with the traditional extensive feeding method, the growth rate is more than doubled.
If feeding goats, the above compound feed can feed 300-350 grams per day, urea can be added to 8-10 grams, and salt can be added to 8-10 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.
The reason for the slow growth of goats and the countermeasures
In general, meat goats bred at 12 months of age weigh less than 15 kilograms, but the growth rate is very slow. The main reason is that due to inbreeding, the constitution is degraded; the second is not paying attention to deworming, and parasites consume a lot of nutrients from the sheep; Without scientific feed, it can not meet the nutritional needs of sheep growth. To increase the growth rate of sheep, the following technical measures must be taken:
