After 10 months of lactation and 3 months of pregnancy, the ewes consume large amounts of nutrients. In order for it to have a chance of recovery and remedy, it is called dry milk. The period from the end of milk production to the birth of the next litter is called dry period. The purpose of dry milk is to restore the physical strength of the sheep, and the breasts are rested to ensure the normal development of the fetus and to store enough nutrients for the next lactation period to lay the foundation for increasing milk production. To achieve the above goals, pregnant ewes must dry milk two months before lambing, and require that the weight of the late pregnancy is more than 20% higher than the lactation peak, otherwise it will not only affect the growth and development of lambs, but also because of the thin and thin ewes, affecting The amount of milk produced by the next child. Dry milk is divided into natural dry milk and artificial dry milk. Ewes with low milk production and poor nutrition will be bred for about 7 months of lactation. After 1-2 months of pregnancy, the amount of milk will rapidly decline and milk production will stop automatically, that is, natural dry milk. High-yielding ewes with good nutritional conditions must take some measures to stop the production of milk, ie artificial dry milk. Artificial dry milk law is divided into gradually dry milk and fast dry milk two. Gradually dry milk method is to change the habits of life, such as changing the number of milking (even for difficult-to-stop milk sheep squeezed every other day), feeding times, change the diet (such as reducing the juicy feed, appropriate reduction of fine material, use more hay, etc. ), to strengthen the exercise to inhibit milk secretion activities, so that the sheep gradually dry milk in 7-14 days. The fast dry milk method is more commonly used in production. This method is better, no need to stop beforehand, it will not affect the healthy development of the ewes and the fetus, but requires the staff to be bold and careful, a strong sense of responsibility. The specific approach is: as long as the date of reaching the dry milk, that is to seriously massage the breasts, the milk squeezed clean, clean the breast nipples and stop milking, while maintaining the mat grass clean. Using this method, it is advisable to dip the soaked teat in a small cup filled with 5% iodine after milking to prevent infection. Then use a small cup filled with collodion to soak each nipple first and then each one. The nipples were immersed for 2 or 3 times in turn and the nipples were closed with collodion to reduce the chance of infection. Penicillin eye ointment could also be injected before the closed nipples as a measure to prevent mastitis. After 3-5 days, the accumulated milk in the breast is gradually absorbed and the breast contraction is soft and rested for about 10 days. The dry milk work is safely finished. The dry milk period can be divided into two stages: the early stage of dry milk and the latter stage of dry milk. The period from dry milk to lactation in the early stage of dry milk completely stops breasts from returning to normal and normally takes 1-2 weeks. The feeding principle during this period is: to meet the nutritional requirements of dry dairy sheep, to stop lactation as soon as possible, it is best not to use juicy feed, use less raw materials, mainly green coarse material. If the ewes are poorly bred, they can still use milk production. The amount of fine feed depends on the quality of the raw material of the green and the quality of the ewes, and for well-worsed ewes, the quality of dry hay can generally only be adequately fed. In short, we must fully meet the nutritional needs of ewes, while paying attention to health management, to strengthen the campaign, to prevent the touch of the breast when scrubbing the sheep, to keep grass bedding clean, pay close attention to breast changes. Dry milk before the end of the period until the end of the dry milk. This section requires that the ewes, especially the ewes that are somewhat less sensible, have a proper weight gain, and the full body condition before the birth is at the upper middle level, which is robust but not fat. Feed should be dominated by high-quality green hay, while feed should be rich in protein, vitamins and minerals. When rations are used, high-quality green hay such as alfalfa, wild green hay, sweet potato vines, and peanut pods should account for 2/3. Silage or multi-feeds such as sweet potatoes, carrots, beets, pumpkins, and potatoes account for 1/3 of the total. The material is only for supplementation. Each sheep is given 0.2-0.3 kg of mixed concentrate per day and 10-20 g of bone meal. This period should be careful not to feed moldy, frozen, corrupt, bulky, non-digestible and easily fermented feeds, nor to drink frozen cold water, and to be frightened to prevent far-off animal husbandry.
