In order to do a good job of crossbreeding of mutton sheep, good mutton sheep with large body size and strong meat-producing performance should be introduced into crossbreeding with local mutton sheep, and a large number of hybrid goats should be bred for raising by peasants. Hybrid goats have the advantages of rapid growth, strong resistance to disease, and lay a foundation for weight gain of mutton sheep.

In general, the broiler sheep kept at the age of 12 months were only 15 kilograms, but the growth rate was very slow. The main reason was that due to inbreeding, the constitution was degraded; the second was no attention to deworming, and the parasite consumed a lot of nutrition of the mutton sheep; Scientific feeds cannot meet the nutritional needs of mutton sheep. To increase the growth rate of mutton sheep, the following technical measures must be taken:

The removal of parasite parasites not only consumes a large amount of nutrients from the mutton sheep, but also secretes toxins and destroys the functions of the digestive system of mutton sheep. Therefore, insects 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.

Scientifically formulated feeds provide sufficient nutrition for fattening mutton sheep, and various nutrients must be balanced in order for sheep to grow rapidly. Now introduce two practical feed formulations:

1. Corn flour 45%, rice bran 20%, bean cake 10%, rapeseed flour 15%, wheat bran 10%, with the 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 kinds of compound feed, can choose a kind of feeding terrier shoots 8. The brake ten. Month old young goats, weighing about 8 kilograms, can feed 150 grams of the compound feed daily when good hay meets the demand. 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 should be cooked 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 with a daily gain of 100 grams to 150 grams. By the age of 6 months, they can weigh between 18 and 25 kilograms, which is more than double the growth rate compared to the traditional extensive feeding method.

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 was designed for caged sheep. For mutton sheep that are grazing in the wild during peak season, the amount of feed with the concentrate can be reduced by 50%. However, no matter how much grass is sufficient, feeding at night is still necessary. In this way, the rapid growth of fattening Boer goats can be guaranteed.
