Prevention of osteomalacia in pregnant sheep in winter

At present, dairy goats have entered the pregnant winter period. In these years, many farmers lack the knowledge of ewes 'reproductive health care and do not realize the importance of preventing and controlling osteomalacia of pregnant sheep to ensure safe childbirth, resulting in dystocia and postpartum paralysis. Therefore, pregnant sheep osteomalacia should be prevented in winter.

Pregnant sheep osteomalacia, is the lack of vitamin D and calcium phosphorus in the body. Pregnant sheep not only need their own nutrition, but also to supply the growth and development of the lambs of the material, so pregnant sheep feed to maintain a different rich nutrition. However, in the lambing period of dairy goats, it is water-cooled grass dry, lack of high-quality green forage in winter, feeding dry forage lack of nutrients, it is difficult to meet the nutritional needs of sheep. In addition, there is little low temperature and light in winter, and the vitamin D produced by sheep receiving sunlight outdoors is also less. If vitamin D, calcium and phosphorus are not supplemented in time in the diet, sheep are prone to osteomalacia, dystocia and postpartum paralysis. Due to lack of maternal nutrition, lambs can have congenital rickets, rickets and even stillbirth. Control methods:

1 strengthen nursing, increase the light before winter to build a good enclosure in time, the best choice for the construction of the enclosure in the leeward sunny place, in order to increase the light and increase the temperature, cold season covered with plastic film and straw curtain, in order to keep warm and cold. Sheep pen damp will make the temperature lower, sheep easy to get sick, to frequently accumulate manure and frequently change the pad soil and clean, keep the pen dry clean and warm. Every time to sheep drink hot soup hot water, avoid feeding frozen grass, drink frozen water. Winter low temperature light less, to seize the favorable opportunity of sufficient sunlight at noon, let sheep more outdoor sun, increase light, is to obtain vitamin D, enhance physical fitness, both effective and economical method.

2. Improve the extensive feeding method of letting sheep nibble straw in previous years, reduce feeding benefit, popularize silage and ammoniated feed, cut green corn stalk and sweet potato vine short, treat with small cellar or plastic film silage or ammoniated feed, make silage and ammoniated feed, which has the characteristics of good palatability, saving concentrate and increasing nutrient sweet value.

3 Reasonable mix of feed, timely add vitamin D and calcium phosphorus diet to feed silage and other feeds for sheep, pay attention to supplementing foods containing vitamin D and calcium phosphorus, such as caviar, bone meal, eggshell and other minerals. Also seize the favorable opportunity before the freezing of the earth, collect and store more vitamin-rich green feeds, such as cabbage leaves, carrots, alfalfa, sweet potatoes, tung leaves, etc., to make up for the lack of nutrients in straw feeds.

4 preventive medication, prevention in advance for the old and weak, limb pain and weakness, walking difficulties of sheep, to early preventive medication, eliminate hidden dangers, to achieve the purpose of disease prevention and treatment. With calcium gluconate tablets, 4 tablets a time, 3 times a day, can add cod liver oil nine with the service, cod liver oil contains vitamin AD, both can promote calcium absorption, and can deposit calcium and phosphorus in the bones, so that the sheep body calcium is sufficiently supplemented, but also can promote development, increase sheep body resistance. 2 weeks is a course of treatment, generally 4 weeks. The weak old sheep can take more until they are cured.
