Ram male ewes mixed
First, it is not conducive to grasp the best breeding time
The rams and the ewes are polycultured and will inevitably freely mate. This may lead to ewes' pregnancy and lambing throughout the year. This is not conducive to feeding and management, but also not conducive to the development of the fetus, the lambs produced are often poor physical fitness, low survival rate. In comparison, ewes produce better lambs in spring and winter, and winter lambs are better than spring. Lamb winter ewes are generally pregnant from July to August. When the grass is lush, the ewes are in good condition, ovulation is high, the conception rate is high, and the fetus is well developed. The lambs are catching up with the weather when they are weaning and can eat grass. Fast growth, strong wintering ability, high survival rate, and high wool production. Therefore, it is advisable to keep the rams and ewes separate from each other. In July and August, the selected ram and ewes will mate. This will ensure that the ewes will produce lambs in December through January of the following year. If the ewes produce lambs in the spring, both the ewes and the lambs can eat grass. Therefore, the ewes have enough milk, the lambs grow fast, and there is no need to purchase large amounts of feed, resulting in low cost.
Second, it is not conducive to grasp the best breeding object
Sheep are usually sexually mature from 7 to 8 months of age, but at this time they are not suitable for breeding. In addition, aged sheep and sick sheep are not suitable for breeding. Only 1.5 to 7.0-year-old healthy sheep are suitable for breeding. If the ram and the ewes are polycultured together and freely mated, the old and the sick, the young and the young will all become pregnant. This not only affects the treatment of old and sick ewes, but also has a low survival rate and slow growth.
Third, it is not conducive to the use of improved rams
A ram can only mate 15 to 20 ewes. If males and females are allowed to mate freely, the energy consumed by the rams will be excessive, which will shorten the useful life and cause waste.
Fourth, it is not conducive to the advantages of hybridization
Freedom of mating is often not sure which lamb is the father of the lamb, resulting in offspring mating, loss of hybrid superiority, and genetic disease.
Fifth, it is not conducive to ewes feeding
Rams and ewes are raised together, and the rams often chase the ewes. The ewes can't concentrate on eating, thus affecting the growth and development of the ewes.
