Ram ewes are not polyculture
Polyculture causes incorrect breeding times Rams and ewes are polycultured and freely mated, potentially leading to ewes' pregnancy and lambing throughout the year. This is not conducive to feeding and management, but also is not conducive to the development of the fetus. The resulting lamb is of poor constitution, low overwintering ability and low survival rate. In comparison, ewes produce better lambs in spring and winter. The lambs produced in winter are generally pregnant in July-August. When the grass is lush, the ewes have good lye, the conception rate is high, and the fetus can also develop well. When the lambs are weaned, they are catching up with the weather and can eat. Grass, fast growth, high survival rate. Therefore, the rams should be kept separately from the ewes. By July-August, the ram should be selected to mate with the ewes. This will ensure that the ewes will breed lambs in the winter. Polyculture can not select the best breeding sheep generally mature in 7-8 months of age. However, it is not suitable for breeding at this time. Only healthy sheep aged 1.5-7 years are suitable for breeding. If the ram and the ewes are polycultured and freely bred, then the old, weak, sick, and disabled ewes will become pregnant. This will seriously affect the growth and development of the young ewe and the elimination of the old, the weak, the sick, and the remnants. . Polyculture can not make full use of the free mating of good breed rams. It will inevitably result in inefficient mating and repeated mating. A ram can only afford the breeding task of 15-20 ewes. At the same time, the ram's energy consumption will shorten the useful life and cause waste. Therefore, rams should be kept separately from ewes. During the breeding period, artificially assist them in mating. Polyculture will result in the free mating of the offspring's illiterate sheep. It is not always sure which lamb is the “father†of the lamb. If it is inconvenient for the selection and breeding of the species, it will inevitably lead to inbreeding and cause genetic diseases and lose the “hybrid advantageâ€. Polyculture affects the normal feeding of ewes and mutton hens. The rams will often chase the ewes so that the sheep will not be at peace. The ewes cannot concentrate on feeding, thus affecting the growth and development of the ewes.
