Fine feeding of Sheep with Poor Feed and susceptible to Disease in Winter

In winter, sheep eat more coarse fodder such as withered and yellow forage, autumn straw, nutrition and palatability are not as good as summer and autumn forage, coupled with low temperature, fast energy consumption of sheep, gradual weakening of fat condition, decreased disease resistance and easy to be infected with epidemic disease, which will lead to ewe abortion or sheep death. It is necessary to raise sheep scientifically and manage them carefully in order to ensure the safety of sheep in winter.

Sheep

Timely elimination of sick and weak sheep:

Sick and weak sheep, poor physique, weak feeding ability, malnutrition, low immune ability, coupled with impermanent temperature in winter, easy to catch epidemic disease, and eventually die. Even though it can survive the winter through treatment and feeding, it also consumes a lot of manpower and energy, increases the breeding cost, and infects healthy sheep after infected with the epidemic disease, resulting in greater losses. Therefore, it is necessary to eliminate sick and weak sheep and choose healthy sheep to spend the winter.

Do a good job of immunization strictly to ensure the health of sheep:

The temperature is low in winter, especially in the northeast, where there is a large temperature difference between day and night, which is the season with high incidence of epidemic disease. Therefore, it is necessary to do a good job of vaccination against foot-and-mouth disease, sheep triple prevention and so on in advance according to the immunization procedures and technical requirements. Prevent multiple epidemics in winter ahead of time, improve immunity, establish effective immune barriers, and ensure the health of sheep. Timely supplement and immunity for postpartum ewes and weaned lambs.

Master the correct feeding and drinking method:

Grazing sheep are fed in the evening and twice in the morning and evening. In feeding order, concentrate should be fed first, then succulent root feed, silage and finally hay and straw. The root should be cut into small pieces, and the dry corn straw should be crushed, chopped, crushed and fed. Concentrate, root feed, silage and so on are all put in the feed trough at one time, and the hay is put in the forage column, with an average of about 1 kg of forage and 0.25 kg of concentrate per sheep per day. Sheep have a good sense of smell, clean eating habits, and like to eat clean forage grass and water. Do not feed straw sprayed with excessive pesticides to prevent miscarriage of pregnant sheep due to drug residues. The forage is dry in winter, so the sheep must drink enough water and eat salt properly, and drink water twice at 9: 00, 15: 00, 16: 00, and the water temperature is about 20 ℃. Do not drink cold water or water with ice residue.

Nursing care of pregnant ewes and lambs:

Pregnant ewes, especially parturient ewes, can not be kicked and driven quickly, and try to avoid shock, crowding and strenuous exercise to prevent miscarriage. Pregnant ewes should be replenished with concentrate according to their fat condition. If conditions permit, the lambing room should be prepared. The room temperature of lambing should not be too low or too high, generally 2 ℃ ~ 3 ℃ is suitable, not only to prevent frostbite lambs, but also to prevent the breeding of bacteria, leading to the epidemic of the disease. It is necessary to separate the postpartum ewe from the lamb and other sheep, separate the lambing ring and mother pen, facilitate management, prevent trampling on the lamb, and facilitate timely breastfeeding of the ewe.

The important point of nursing newborn lambs is to remove the mucus in the oral cavity and nasal cavity in time to ensure the smooth flow of the respiratory tract. In order to let the lamb eat colostrum within 1-2 hours, do not be overfed for the first time. Pay attention to prevent lambs from freezing, hunger, fullness, pressure, illness and so on. If one child gives birth to more than two lambs, the lamb should be artificially fed or breast-fed by other ewes in time. The method of breast-feeding is to wipe the ewe's urine on the head and body of the lamb, and at the same time help eat it several times.
