Breeding lambs is an important and meticulous work, if the feeding management is not appropriate, it will be directly related to the interests of farmers. The focus of lamb rearing is to grasp the lamb lactation and replenishment work, followed by the main to do a good job of cold and warmth, strengthen management.
First, the feeding management of the first rising lamb
General ewes in lactation after 20 days, the quality of breast milk began to decrease, and this time the weight of the lambs will gradually increase, the need for nutrition is also increasing, it must be external nutritional supplements. Lambs born 7 days to 15 days after weaning during the lamb ration formula for corn 50%, 30% soybean meal, whey powder 10%, 5% fat powder, salt 0.5%, 0.5% calcium phosphate, 4% fattening sheep premix. Due to the lactation period, lambs feed less concentrate, lambs on the nutritional requirements of relatively high, so add 10% whey powder inside the concentrate, its lactose composition to facilitate digestion and absorption. The lactose content can also be increased if conditions allow. Lambs absorb breast milk to ensure nutrition at the same time, and then feed concentrate and forage to absorb nutrients, thus ensuring rapid growth needs.
Second, the feeding management of the growth period of lambs
The growth period refers to 15 days after weaning to 100 days of age, during this period of concentrate feed can be used corn 54.5%, soybean meal 30%, whey powder 5%, fat powder 5%, baking soda 0.5%, salt 0.5%, calcium phosphate 0.5%, fattening sheep premix 4%. The growth phase is mainly for the lambs to grow bones, and the calcium and phosphorus requirements are relatively high during this period. Lamb lacks sugar in captivity, 5% whey powder is added to the feed at 15-100 days of age after weaning to meet the lamb's protein and sugar requirements. The growing season feed is important as the frame is important at this stage and provides a solid foundation for later fattening. With the increase of day old, the digestive organs are also maturing, especially the gradual improvement of rumen.
Third, lamb breeding skills
1.Time to eat the colostrum
When lambs are born, the foregut is not yet mature, the microbial area is not yet established, and the ruminant function is not sound. So the day the lamb is born, it must be allowed to eat the mother's milk, commonly known as eating colostrum. Colostrum is rich in protein, vitamins, minerals and other nutrients, colostrum contains a large number of antibodies, while the lamb itself can not produce antibodies. Timely consumption of colostrum is the key to improving the resistance and survival rate of lambs. Even if the ewes have no milk after giving birth or the ewes die in childbirth, the newborn lambs should be allowed to eat the colostrum of other ewes, otherwise it is difficult for the lambs to survive.
2.Feed concentrate at the right time
With the rapid growth of lambs, while the lactation of ewes has declined, in order to meet the nutritional needs of lambs, supplemental feed is to increase the weight of lambs, enhance the necessary measures to combat disease. So after a week after the birth of the lambs, we should start to teach them to eat the right amount of fresh grass and young leaves. 20 days of age can be close to the grazing, appropriate supplemental feeding concentrate feed. Concentrate feed should be nutritionally comprehensive, easy to digest and absorb, but also through the crushing process. Feed concentrate feed to do less to give, diligently add, not leftover material. When feeding green fodder, it should be chopped and mixed with concentrate fodder.
The ratio of concentrate feed is: corn 5 kg, wheat bran 1.5 kg, soybean meal cake 2 kg, cottonseed cake 1.5 kg, appropriate amount of vitamins. Concentrated feed supplement feeding amount is: half-month collar 75g per head per day, 100g at 1 month of age, 200g at 2 months of age, 250g at 3 months of age.
3.Lactation management
Lambs should be born within a week with the ewes to live together, so that they can be late at any time breastfeeding, enhance the mother-child relationship. If the lambs have difficulties in breastfeeding, they need artificial breastfeeding, and the artificial breastfeeding should be done on time, according to the amount, according to the temperature.
4.Timely dehorning and de-stressing
Two weeks after the birth of the lambs should be healthy and disease-free, good body condition of the lambs to go to the horn. To prevent adult fights and injuries and abortion, but also to reduce the occupancy area of the feeding trough, easy to manage. Non-breeding rams should be dehorned one month after birth, dehorned rams are docile, easy to manage, easy to fatten.
5.Preventing cold and keeping warm
Lambs are very sensitive to changes in external temperature and have poor thermoregulation. After the lambs are born, the ewes should be allowed to lick the body dry as soon as possible. If the ewes don't lick in time, they should be wiped dry with a clean rag. In winter, there should be warming equipment, the ground is padded with soft hay, and the temperature of the house should be kept above 5℃.
