First, prevent ewes from matching
From a physiological point of view, ewes generally reach sexual maturity within 5 to 6 months of age, and have reproductive abilities. The occurrence of estrus occurs for the first time, but the ewes are not yet mature. Therefore, for goats, the first breeding time of ewes should be selected when the sheep has reached maturity. This will not only not affect the health of the ewes, but also provide a healthy young sheep.
Second, adhere to the correct body matching principle
In difficult-to-produce cases, about 50% is related to the fetus is too large, most of which is due to the use of large-scale species of ram, especially when the ewes are not mature mating large rams, the incidence of dystocia is higher . Therefore, we must adhere to the correct one-piece matching principle. The principle of matching the correct body size should be: large, large, medium and small, and can not be large and small. The results with large and small children often lead to the fetus is too large and increase the occurrence of difficult-to-yield, the consequences for premature breeding more serious.
Third, do a good job of feeding and management during pregnancy
Goats are difficult to produce, and malnutrition during pregnancy is also one of the causes of dystocia. Over-obesity or malnutrition in ewes during pregnancy can lead to insufficient productivity and induce dystocia. At the same time, exercise is essential for pregnant ewes, and a number of difficult-to-eating ewes are associated with lack of exercise during pregnancy. Insufficient movement of pregnant sheep may induce fetal malposition and may also lead to insufficient productivity. Both of these are direct causes of dystocia. For ewes, reasonable exercise must be appropriate, and second, moderate. Usually 2 hours a day is appropriate.
