We have already introduced the management of breeding and breeding feeding of the Jianyang big eared sheep using Jinbao fermented bed sheep breeding. Now we continue to look at the experts of the Jinbao breeding to determine the ewes' entering. After pregnancy, how should we raise and manage it? Which of these points need special attention?
Jinbao breeding experts emphasized that when using Jinbao dry-fermenting bed to raise sheep with Jianyang big ear, when it is determined that the ewes enter the gestation period, the ewes during pregnancy need to be meticulously conditioned by the farmer to prepare for the baby's birth. ready. Pregnancy can be divided into two management stages: pre-pregnancy and late pregnancy.
Pre-pregnancy is the first 3 months of pregnancy. Due to the slow development of the fetus, the nutrients needed are not more than the empty period. Therefore, there is no difference in the feeding of the ewes and the fermentation formula of the feed starter during the empty period. The amount of feed can also be fed according to the feeding amount during the empty period.
Late pregnancy is a management stage that requires special attention. Late pregnancy is the last 2 months of pregnancy. At this time, the fetus grows and develops rapidly. 80% to 90% of the birth weight is formed during this period. The ewe's need for nutrition and vitamins is significantly increased. At this time, the formula of the mixed concentrate was adjusted to 65% for corn, 20% for soybean meal, 6% for rapeseed cake or humus cake, 8% for wheat bran and 1% for salt. When feeding, the amount of hay fed by each ewes is 3,500 grams per day, the amount of concentrate feed is 300 to 400 grams per day, and the hay is mixed with the concentrate and fed once a day in the morning and at night. At the same time, each sheep is fed 1000-1500 g of high-quality forage grass every day. At this time, the management of ewes should be strengthened to reduce the density of rearing cages produced by Jinbao fermentation beds and to prevent crowding and slipping during feeding of drinking water. Ewes who have horned or often fighting should pay attention to isolation. Feed moldy, frozen feed, pay attention to drinking clean water when drinking water, warm water is preferred in winter.
The ewes after pregnancy diagnosis can calculate the general expected date of birth according to the method of “five months plus three days minus†for the breeding date. For example, on April 8th, pregnant ewes will have their expected date of birth around September 5. The delivery room also uses the sheds on which the technology of depositing the sheep's milk on the fermentation bed is used. It requires bright and spacious, dry ventilation, and good insulation properties. When the ewes are in normal delivery, the amniotic membrane comes out from the vulva. The amniotic membrane is a white, translucent cyst. The membrane contains fetal and amniotic fluid. The fetus in the amniotic membrane tries to break through the amniotic membrane after birth, and the lamb can be produced after the amniotic membrane ruptures. If two or more lambs are produced, they will be separated by 5-30 minutes, but sometimes they will last for more than a few hours. After the lamb is produced, the breeder should first wipe the mucus of the lamb's mouth and nose to prevent suffocation, and then let the ewe lick the mucus on the lamb's body. The ewes' mummification of the mucus in the lamb can play a role in keeping warm. Anti-fresh lambs are chilled, and they also have the effect of confirming their offspring. Most of the umbilical cords of the lamb are naturally broken and not broken. The scissors that have been sterilized can be cut at 4 cm from the abdomen and sterilized with iodine. It is necessary to ensure that the colostrum is eaten in time within half an hour to one hour after delivery. Colostrum is commonly known as colloidal milk. It contains various nutrients needed for newborn lambs, which are easily absorbed and can increase the immunity of the sheep. The lamb can walk up to 1 hour after birth to search for ewes to eat colostrum on its own. However, if the lamb is unable to eat colostrum on its own, staff will need to do certain supplementary work to ensure that the lamb eats colostrum, and the next 7 days Eat good colostrum within. The newborn lambs and the lambs born from a single birth can find nanny sheep milk substitutes.
The newly born ewes have great physical and water consumption, poor digestive function, and should be given easily digestible quality hay and clean drinking water. Within 1 to 3 days after lambing, the ewes can feed less concentrate if they have good lye. It is better to use 300-350 grams per ewes per day and feed more quality hay. Each ewlet feeds 3500-4000 kg of hay on a daily basis. The hay and concentrate are fed together and fed once each morning and evening. At this time, the amount of feed for pasture is maintained at about 1000-1500 grams per day per sheep, and they are also fed once a day in the morning and at night.
