Winter precautions against bovine abortion
Due to the large changes in the weather in winter and the threat of hay, frost, lack of green feed, and cold, the impact on pregnant cattle is even greater. Therefore, it is necessary to fully grasp the management of dairy cows during pregnancy, focusing on the prevention of pregnant cattle abortion, to ensure its safe winter. 1, to strengthen nutritional needs. In order to ensure winter, it is necessary to grasp the sensation of late pregnancy, in addition to maintaining the nutritional needs of its own life activities, but also to meet the nutritional requirements of the rapid growth and development of the fetus, which must be fed a variety of nutritious feed . In order to stabilize the nutritional balance of pregnant cows, it is not possible to suddenly change the feed, and it is necessary to provide timing, quantitative, and coarse first and then fine feeding methods to improve calves, prevent cold, reduce body temperature loss, etc., in order to ensure the birth of yak body. Large, strong, strong disease resistance. 2. Give pregnant cows plenty of water. In winter, the majority of cows mainly eat dried hay. If there is insufficient drinking water, saliva will be reduced and digestion will be weakened, which will slow down the cow's rumen motility and even accumulate food, resulting in obstruction of the valve. Therefore, in winter, pregnant cattle should be warmed to reduce heat loss. 3, to strengthen thermal management. The optimum temperature for cattle is 8°C~15°C, which is the favorable temperature for the prevention of miscarriage and miscarriage of pregnant cows. Its effective approach is: close the doors and windows of the cowshed, plug loopholes to prevent the intrusion of thieves; the ground should be dry, not on the cold, to prevent the cold and wet; to do the wall is not windy, not to freeze, the shed does not hang frost, so pregnant cows have a A good wintering environment. In the morning after the frost appeared, it was not possible to grazing cows to prevent the frost from damaging the pregnant cows. Because in the morning the cows are hungry, their stomachs are empty, they are bulimia, and they often bulge due to overeating and may even swell. Pregnant cows are more prone to fetal movement, restlessness or miscarriage. If cattle are to be grazing, grazing should be carried out in the morning when the sun comes out and when there is no dew.
The kit is used for in vitro qualitative detecting the ORF1ab/N genes of novel coronavirus 2019-nCoV and Delta Variant in respiratory specimens including oropharyngeal swabs, nasopharyngeal swab, sputum and bronchoalveolar lavage fluid, and performing D950N mutation detection of Delta variant of Novel Coronavirus 2019-nCoV.
As reported in GISAID database, more than 95% Delta variant of Novel Coronavirus 2019-nCoV carry D950N mutation.
