According to the experience of mutton sheep breeding accumulated for many years, the author has outlined the technical points of winter feeding and management of pregnant ewes as follows, hoping to benefit mutton sheep farmers.
According to nutritional requirements, a reasonable supply of fodder and forage is the material basis for the production of mutton sheep. According to the nutritional needs of pregnant ewes, a reasonable supply of fodder is the basic measure for raising pregnant ewes. For gravid sheep that have stopped milking, because of their greater nutrient consumption during the milk production period, special attention must be paid to feeding and management to provide enough nutrients for the body to recover as soon as possible to meet the maternal and fetal growth and development needs. For ewes who are immature and pregnant, they need to be biased and carefully fed. It is mainly based on high-quality dry feeds, with a small amount of green feed. In the later stages of pregnancy, the fetus needs a lot of nutrients from the mother. Therefore, it is necessary to gradually increase the amount of concentrates and succulent feeds rich in protein, minerals, vitamins, and generally increase the amount of concentrate by 1 to 2 kg. However, the amount of concentrate should be controlled 5 days before lambing. In conclusion, the feeds fed throughout the pregnancy should not only be rich in nutrients, but also not be fat and easy to digest. Feeding should be timed, quantified, set temperature, set quality, and must not be fed with mildewed and frozen feed.
Doing a good job of maintaining the sheds, strengthening daily management, maintaining the sheds, and strengthening day-to-day management are important guarantees for ensuring the normal growth and development of pregnant ewes and high-yield multiple births. It is necessary not only to repair the pens and prevent the intrusion of thieves, but also to achieve "one, two, three, and four services." One guarantee is to ensure that the pens are clean and dry and warm; the second is to use warm water to let the sheep drink, use hay or dry bar; third is not a pen and don't enter the wind, no rain, no moisture; four Qin is a circle clerk pad Grass, diligent grass cleaning, diligent cleaning, and dung removal; at the same time, absolutely avoid kicking, frightening, and fighting with other sheep or other animals. If there is no snowstorm, proper exercise or grazing should be maintained every day. When you exercise, you must be careful not to go too fast. You must choose a flat place for exercise. Do not go steep slopes and cross the ditch. Should be separated from the ram to prevent strong matches. Do not fight cold whip, so as not to panic sheep. Two months after pregnancy, milking should be stopped to ensure that the ewes are healthy and have good fetal development.
Strengthen disease prevention and control to ensure that the birth of multiple births should be implemented in accordance with the principle of prevention and treatment, from the strengthening of the body and disease resistance of pregnant sheep, and effectively improve feeding management. Special attention should be paid to non-feeding mildew, acidity, freezing and toxic feeds, not drinking cold water and dirty water, and not drinking water on an empty stomach. Sheep feeding troughs should be regularly sterilized to ensure cleanliness. At the same time, we must pay close attention to the changes in the weather and take precautions as early as possible to avoid the sudden fall of winds and cold currents that may cause sick ewes. Usually also pay attention to observe the spirit of the pregnant sheep, diet, action and fecal excretion, abnormalities should immediately seek professional veterinary treatment.
