The lack of postpartum milk in the ewes has been a problem that has plagued the survival rate and growth rate of lambs. In recent years, this issue has become more apparent as the scale of sheep raising has increased. To this end, we must attach great importance to early response.
1. Dairy (Baby Sheep)
The problem of ewes giving birth to a single lamb or lack of lactation in the ewes of the ewes, or death of the ewes when they were lambs, leaves solitary lambs. The best way to do this is to use milk replacer, that is, to use a nanny sheep. This way you can reduce the amount of work during the post-lactation period, and the growth of the lamb is not greatly affected.
If the ewes died while they were lambs, apply the amniotic fluid from the newborn lambs to the nose and nose of the nanny sheep in time, and then guide the nanny to lick the mucus on the lambs to complete the milk replacement process. Of course, the premise of such treatment is that the time of delivery of the nanny sheep and the distance between the dead ewe should not be too long.
If the ewes are bred with lambs after giving birth, the ewes are found to have little or no milk, and it is best to choose ewes with postpartum lambs that have died and have enough milk as nanny sheep, or lambs that produce single lambs but have high lactation performance. As a nanny sheep, this can prevent ewes from causing mastitis due to breast swelling, and it can also help lambs grow well. In addition, dairy goats can be kept as specialized nanny sheep. However, when this method is adopted, it is often necessary to manually fix the ewes and allow the lambs to feed on the milk. After many trainings, they can succeed.
Among the lambs that are given birth and many lambs, strong lambs are to be chosen for the nanny sheeps, and for the weak lambs to be sucked for their own ewes. Under conditional conditions, the lamb should be allowed to eat the colostrum's colostrum first, and then the nanny sheep should be replaced.
2. Manual nursing
Sources of milk substitutes that can be used for artificial breastfeeding can be classified as fresh milk or milk substitutes. The methods used are: First, pot drinking method. Put the milk or milk replacer into the water basin and allow the lamb to drink. At the beginning, the sucker will shorten, polish, and wash the fingernail, and suck on the forefinger or middle finger to suck the lamb and slowly lure the lamb's mouth. After drinking milk, after several trainings, the lamb will drink milk from the pot. The second is breast milk drinking method. Place the milk in a breastfeeding device or a milk bottle. Apply milk to the teat and stuff it into the mouth of the sheep. Train several times and the lamb can gradually learn to suckle. Give the lambs artificial breastfeeding and do the following two things:
1 Timing and quantification: Regular ration means that breastfeeding time and feeding amount should be reasonable. In general, newborn lambs should have short nursing intervals and less quantity. With increasing age, they gradually increase the interval and amount, and reduce the interval after 50 days. And give the amount. 1 to 5 days of age free nursing; 6 to 10 days of age, 4 times/day, 220 grams of raw milk each time; 11 to 50 days of age, 4 times/day, 250 to 350 grams of raw milk each time; gradually reduced after 50 days Number of times and amount; Stop breastfeeding after 90 days.
2 Fixed temperature, constant quality: Fixed temperature refers to artificial nursing milk temperature should be close to or slightly higher than the ewes body temperature, that is, the mouth temperature can not be less than 38 °C, the temperature is too low can easily cause diarrhea. In addition, raw milk or milk substitutes must ensure quality and pay attention to hygiene.
3. Early feeding
Lambs that are milk substitutes or artificially nursing need to start feeding as early as possible. After 10 days of age, the grass will be given to the grass. The grass will be hung in the air to allow the lambs to feed freely. After 20 days, the animals will start to feed and 40 to 50 days after the feeding. Milk, the best use of special lamb material, since the ingredients pay special attention to dietary energy, protein nutrition and full price, dietary digestible protein with 16% to 20% is the best, digestible total nutrients to 74% It is appropriate. Generally free to eat.
4. Preventive measures
In the daily feeding and management work, the adoption of measures can effectively prevent and reduce the occurrence of milkless and milkless conditions in the ewes.
1 Choose the best kind. Scale farms should establish a complete production file, and pay attention to preservation and sorting. When choosing a reserve sheep, select the offspring of the sheep with relatively good lactation performance to cultivate them, which can greatly reduce the probability of occurrence of such problems.
2 strengthen management. For the different nutritional needs of the ewes at various stages of pregnancy, respectively, to strengthen the supply of nutrition, especially in the late feeding and management of ewes to highlight the supply of calcium and protein nutrition, to ensure the dual needs of ewes and fetus development, This will minimize the problem of insufficient milk in the ewes after childbirth.
