The four key links in winter sheep management

A: In the winter, the weather often changes drastically. The northern ewe is in the maternity phase of breeding and the sheep should focus on the following key tasks.

● Warm

Sheep's cold tolerance is relatively strong, but winter sheep can not be less than 0 °C, lambs can not be less than 8 °C, the delivery room is maintained at 15 °C -18 °C is appropriate. Before the winter, it is necessary to repair the sheep house as soon as possible.

● Nutrition

In order to survive cold in winter, the flock must make up for the quality of hay and crop stalks, supplement soybean meal, corn, dried melon, and wheat bran in a timely manner to ensure that each sheep can eat 200 to 250 grams of concentrate each day. The sheep replenished 5-10 grams of salt a day, so that the sheep's appetite is strong, growth and development are good, can not afford to lose weight, and the flock is robust. Reserved for the use of small rams and ewes, each sheep should be fed daily 500-600 grams of concentrate. Daily supply of water 2-3 times a day, preferably light salt water, water temperature around 18 °C.

● Baotai

It is necessary to do scientific feeding, separate male and female ewes, and sheep in different growth stages, and feed them according to nutritional requirements of sheep at different stages. The number of pregnant ewes is suitable to ensure that the area of ​​each pregnant sheep is 2-2.5 square meters to prevent accidental squeezing of pregnant sheep. Supply fine ingredients and light salt water, avoid drinking ice water, eat frozen grass, and ensure that the feeding is reasonable. We must strengthen day-to-day management and prevent internal battles, fights, collisions and other acts within the flock to prevent frightened, jerked, and slippery pregnant sheep.

●Prevention

In the winter, it is necessary to strengthen the prevention and control of herds’ comprehensive disease. In winter, sheep are susceptible to diseases such as foot-and-mouth disease, streptococcal disease, pox disease, dysentery, cold, and E. coli disease. In the late autumn and early winter, the sheep should be immunized in time. Before the winter, we must also promptly carry out preventive deworming. Commonly used drugs include trichlorfon, ivermectin, thiodichlorodichlorophenol, quinacridone, and chlorbenzuron. In order to keep the house clean and dry, remove the manure in time, perform harmless treatment by heaping fermentation, and filter the residue. In the deep winter season, at noon on sunny days, it is also necessary to allow the sheep to go out to exercise, in order to enhance physical fitness and improve cold resistance.
