Sheep winterization and fine feeding technology
In the winter, most of the farmers use yellow fodder and autumn stalks as the main feed to feed sheep. The nutrition and palatability are not as good as those in summer and autumn. In addition, the temperature is low, the energy consumption of the sheep is faster, and the sensation gradually weakens. Reduced ability to become infected with the disease can lead to miscarriage of ewes or death of large numbers of sheep. In order to ensure safe wintering of the flock, it must be scientifically reared and carefully managed. The author believes that the following aspects should be taken into consideration:
First, timely elimination of sick sheep
The sick and frail sheep have poor body quality, poor feeding ability, malnutrition and low immunity. In addition, the temperature in winter is variable, and they are easily infected with various diseases, eventually leading to death. Even if wintering can be achieved through treatment and careful breeding, it will take a lot more manpower and effort than healthy sheep breeding, which will increase the economic cost of breeding, and it will also infect other healthy sheep after infection, resulting in greater economic losses. Therefore, we must eliminate sick and weak sheep, preferably the healthy sheep group for the winter.
Second, strict immunization to ensure the health of the sheep
The low temperature in winter and the large temperature difference between day and night are the high season for many animal diseases. Therefore, immunization with vaccines such as foot-and-mouth disease and sheep triplets must be done in advance according to the immunization procedures and technical requirements. Advance the prevention of multiple epidemics in advance in winter, improve the body's immunity, establish an effective immune barrier, and ensure the health of the sheep. For postpartum ewes and weaning lambs, it is necessary to do a good job in time to exempt the vaccine.
Third, master the correct feeding and drinking methods
Grazing sheep are fed late in the evening and are fed twice in the morning and evening. The feeding sequence should first feed the concentrate, then the juicy root feed, then the silage, and finally the hay and dry straw. Roots should be cut into small pieces and dried corn stalks should be crushed, chopped or crushed and fed. Concentrates, root feeds, silage, etc. should be placed in the feed tanks at the same time. Hay is placed in the forage bar. Each sheep feeds about 1 kilogram of grass per day, and the concentrate is about 0.25 kilograms. Sheep's sense of smell is sensitive, clean and clean, like to eat and drink clean forage and water. When straw is used, straw that is sprayed with excessive amounts of pesticides cannot be fed to prevent miscarriage of pregnant ewes due to drug residues. In winter, the forage grass is relatively dry, and it is necessary to ensure that the sheep drink plenty of water and give appropriate salt, and drink water from 9:00 to 10:00 and from 3 to 4 in the afternoon. The water temperature is generally around 20°C. Do not drink cold water and water with hail.
IV. Nursing of pregnant ewes and postpartum lambs
The pregnant ewes, especially the ewes who are giving birth, cannot kick or swiftly drive away, and try to avoid scaring, crowding and strenuous exercise to prevent miscarriage. Pregnancy ewes should be supplemented with concentrates according to the lyrics. Ladder rooms should be prepared for conditions. Lamb indoor temperature can not be too low or too high, generally 2 °C ~ 3 °C is appropriate, not only prevent freezing lambs lambs, but also prevent the growth of bacteria, leading to the epidemic. To separate the postpartum ewes from the lambs and other sheep, separate the lambs and mothers' stalls for easy management, and prevent them from stepping on the lambs.
It is very important for newborn lambs to get rid of mucus in the mouth and nose to ensure that the airway is clear. Let the lamb eat colostrum within 1 hour to 2 hours. Don't overfeed for the first time. Pay attention to prevent lambs from freezing, being hungry, full, stressed, and diseased. If there is more than two lambs in a single birth, the lambs shall be artificially fed or the other ewes shall be breast-fed on time. The method of milk replacement is to wipe the urine of the ewes on the head of the lamb and the body of the lamb. Can be the second.
