Lamb feeding (1) feeding
1. Eat bovine colostrum early: bovine colostrum plays a particularly important role in the health of lambs. Lambs are generally required to eat colostrum within 2 hours after delivery, so that they will be physically strong, have strong disease resistance, grow fast and have a high survival rate. /kloc-lambs under 0/month should be mainly breastfed, supplemented by forage.
2, early feeding, early feeding: 40 ~ 80 days after birth, like breastfeeding, lambs have learned to eat forage, so they should be fed early in time. Early supplementary feeding can not only make lambs get more complete nutrition, but also promote the development of digestive organs. Diet should be composed of high-quality green grass, hay, bean cakes and fish meal rich in protein. Pay attention to breastfeeding less, don't stay overnight, breastfeed regularly, and of course, add enough vitamins such as calcium and phosphorus.
(2) Management
Lambs should eat colostrum as soon as possible after birth, because colostrum contains complete nutrients and antibodies, which has laxative and disease-resistant effects and is extremely important for the growth and survival of lambs. 1 Breastfeeding is carried out under the supervision of people.
Lactating lambs develop rapidly. If the milk is insufficient, it will not only affect the growth of lambs, but also easily get sick and endanger their lives. For dairy sheep, you should find a nanny sheep. If the nanny sheep won't let the lamb who sent the sheep eat milk, we can put some kerosene on the nanny sheep's nose and mouth and the lamb's body at the same time, or put the nanny sheep's milk and urine on the lamb's body and put the nanny sheep and the lamb together in a dark room. After a few hours, the nanny sheep can recognize the lamb by itself. You can also force the lamb to breastfeed many times, so that the nanny sheep and the lamb can recognize each other. Specifically, one person fixes the ewe, and the other person holds the ewe's hind legs, so that the lamb can breastfeed and train many times. If necessary, you can also breastfeed artificially. Artificial breastfeeding should be done regularly, quantitatively, at constant temperature, kept clean and hygienic, and strictly disinfected.
Lamb meconium is dark brown and sticky, and can be discharged within 4 ~ 6 hours after birth. If the fetal feces are still not discharged after 24 hours, measures such as enema should be taken. Meconium is very sticky. If the anus is blocked, it should be cleaned in time.
In order to facilitate management and prevent confusion during breastfeeding, the number of ewes can be written on the back of lambs for easy identification.
Proper exercise. Exercise can increase the appetite of lambs, enhance their physique, promote growth and reduce diseases. As the lambs grow older, they should be driven to a nearby pasture to graze and strengthen the lamb movement.
Lamb fattening management (1): In recent years, some foreign countries that produce fattening lambs have expanded the scale of fattening in houses to varying degrees and taken the road of specialization and intensification. Because the fattening and growth and development of lambs are carried out at the same time, the feed is required to be rich and comprehensive in nutrition, good in palatability, sufficient in protein and high in energy, and all kinds of necessary minerals and vitamins should be fed.
Taking 3-month-old weaned lambs as an example, the diet consists of 45% corn, 15% bran, 8% cottonseed cake, 30% peanut vine powder, 0.5% salt, manganese, selenium and other trace elements and 2% multivitamin additive. Single and double lambs were fattened by pure house feeding, and the weight of 4-month-old lambs was 35 kg.
(2) Grazing and fattening in house: for 4-month-old lambs, the combination of house feeding and grazing is adopted, and the diet consists of 43% mixed concentrate such as corn and cottonseed cake, 57% ammoniated straw and additives such as minerals. Concentrate should be fed after grazing every day, and 10 ~ 15g salt should be fed every day. Four-month-old weaned lambs were fattened with high-energy and high-protein diet for 60 days. Each lamb consumes total metabolic energy of 48 1.20 mj, digestible crude protein of 4648.82g, daily gain of182.75g, carcass weight of18.12kg, and the slaughter rate is over 50%.
Prevention and treatment of lamb blight (1) scientific feeding and careful management; Adhere to scientific grazing and reasonable supplementary feeding, and strive for diverse feed types and rich nutrition; Do not feed frozen or moldy feed, and do not drink stagnant water or sewage; The sheephouse is clean and dry, with fresh air and plenty of sunshine, which is warm in winter and cool in summer.
(2) Do a good job of preventive disinfection, and carry out preventive inoculation regularly: in combination with daily feeding management, carry out preventive disinfection on sheephouses, utensils and sports fields on a regular basis. If 3% Lysol or 20% fresh lime, 2% plant ash, Yujieling and other commonly used disinfection drugs are used, they are generally thoroughly disinfected/kloc-0 times in spring and autumn respectively. When infectious diseases occur, it is necessary to carry out surprise disinfection to kill pathogenic bacteria, such as using caustic soda or flame to extinguish fire and disinfect. Pay attention to timely cleaning, accumulation and sealed fermentation to kill pathogenic bacteria and parasitic eggs or cercariae in feces.
Master the situation and laws of local infectious diseases, select vaccines in a targeted manner, and carry out preventive injections regularly to avoid the occurrence of infectious diseases. Commonly used vaccines, one is the anaerobic triple vaccine of sheep, which is used to prevent sheep anthrax, sheep epidemic disease and sheep enterotoxemia. The dose is 1 time, 3 ml of lambs less than half a year, 5 ml of sheep over half a year, and the immunization period is 6 ~ 8 months; In February, live attenuated Brucella ovis vaccine No.5 1 ml was injected subcutaneously or intramuscularly, and the immunization period was 1 year. To prevent anthrax, 0.2 ml anthrax spore vaccine can be injected under each sheepskin, and the immunization period is 1 year; To prevent tetanus, tetanus alum was used to precipitate toxoid, and 0.5 ml was injected subcutaneously into the neck at 1/3. The immune period was 65438 0 years.
(3) Pay attention to insect repellent and rodent control. ：
Parasitic diseases of sheep are very common, and those who suffer from heavy sheep are life-threatening, while those who suffer from light sheep are emaciated, grow slowly and have a serious decline in production performance. All localities should pay attention to the work of deworming, and regularly carry out prevention and deworming in spring and autumn every year. Sheep are susceptible to infection and harmful parasites, such as tapeworms, nematodes and Fasciola hepatica. To drive out tapeworms and nematodes, albendazole can be taken orally, with a dose of10 mg per kilogram of body weight; Nitrocochlorophenol is used for Fasciola hepatica, weighing 3 ~ 8 mg per kilogram. The feces of sheep should be collected in time within 0/0 day after deworming, and sealed for fermentation to prevent the driven eggs or cysts from being swallowed and infected by sheep again.
