The impact of ewe lambing rate on sheep raising efficiency is very large, but some sheep farms can make ewes produce two litters a year, and some sheep farm ewes can't even produce three litters for two years, in this case, the latter sheep raising benefits will certainly not be too ideal. But what's the trick to getting ewes to produce two litters a year? Today Xiaobian will give you a detailed introduction.
First, choose a high-yielding product
There are many breeds of sheep, not all breeds can produce two litters a year, such as purebred Dubo sheep, Boer goats and other breeds, which are mostly single-season estrus, only in the autumn of the year, this sheep can only produce one litter a year. Ewes should choose breeds that can be in heat all year round, such as small-tailed cold sheep, lake sheep, Duhan hybrid sheep, green sheep and hybrid Boer goats, etc., only throughout the year can there be a chance of two litters a year.
Second, do a good job of postpartum anti-inflammatory
Postpartum uterine infection of ewes is a major cause of estrus and conception, so ewes must do a good job of nursing and anti-inflammatory work after childbirth. Ewes should be transferred to a clean, hygienic pen when they are born, and if the ewe can produce normally, let the ewe produce normally as much as possible, and if you need to help give birth, you must carry out strict disinfection. In the case of normal delivery, smooth discharge of the fetal coat and normal postpartum lochia, postpartum anti-inflammatory, but if the ewe is midwife, the fetal coat is not under the condition that the lochia is abnormal, the ewe needs to be injected with drugs such as cefotafurofuran sodium, lincomycin or enrofloxacin for postpartum anti-inflammatory.
Third, drink motherwort water
Emu can drink motherwort water after childbirth, use motherwort fresh grass 250 grams, or hay 100 grams, boil water for postpartum ewes to drink, once a day, for 7 days, can speed up lochia discharge, promote uterine recovery, reduce inflammatory infection, as long as the feed nutrition can keep up, ewes basically wait for the lamb full moon can be mated in heat, and the mating fertility rate is relatively high.
Fourth, increase feed nutrition
In the case of ewes producing multiple lambs, their nutritional needs for feed are high, and if the nutritional needs are not met, it will affect the normal estrus breeding of ewes. According to the number of lambs in the ewe, the feed nutrition begins to gradually increase after 3 days after the ewe gives birth, and it is also necessary to pay attention to the supplementation of nutrients such as green and juicy feed, trace elements, vitamins and other nutrients, as long as the ewe nutrition is satisfied, the ewe can soon enter the next production period after childbirth.
Fifth, the lamb is replenished as early as possible
Feeding lambs as early as possible can improve the growth rate of lambs on the one hand, and reduce the lactation pressure of ewes on the other hand, and excess nutrients can promote ovulation in ewes. Lambs generally start to use some fragrant and sweet feed for open feeding around the age of 10 days, and then gradually increase the amount of feed, and after 20 days of age, they must be fed some soft green hay to promote the development of the lamb's rumen.
Sixth, do a good job of estrus observation
The first postpartum estrus of a ewe may not be too obvious, while the average estrus cycle of sheep is 17 days, the average estrus cycle of goats is 21 days, and if you miss it, you have to wait 17 days or 21 days before you can, so you must do a good job of ewe estrus observation. Ewes have a decreased appetite, feeding does not go into the groove, other sheep are eating grass, but it is swirling in the back, there will be crawling across other ewes, or by other sheep chasing and climbing across the phenomenon, basically you can determine that this ewe is in heat, should be bred in time.
As long as you do the above 6 points, your ewe can also produce two litters a year.
