From March to March, it is the lamb's lambing season. The technical staff went down to the sheep spot and exchanged views with the herdsmen on matters that should be noted by the ewes during this period.
Due to the drought last year, the quality of forage grass was not good, the yield was not high, and the nutrient content was insufficient. As a result, the ewe was not as good as it was in previous years. The ewes are lean and affect the survival of the lambs. Therefore, it is necessary to strengthen the feeding and management of the ewes before lambing.
1, to ensure adequate drinking water. Must be the sheep to drink normal temperature water, conditional water can be warmed, lean sheep is particularly important.
2, make up enough pasture, improve the proportion of concentrate feed; reduce the grazing time, do not leave the animal husbandry point too far, in the grazing process, do not let the sheep go too fast, reduce the sheep's physical exertion, to ensure that the ewes sensation .
3. The proportion of herdsmen with insufficient pasture storage should not be too large when feeding silage. When feeding, add appropriate baking soda to prevent excessive acidity; do not feed frozen silage to prevent ewe. abortion.
4. Strengthen the maintenance of the warm circle and respond to sudden weather changes; keep the pens clean, clean up the falling wool, prevent the lambs from swallowing to form hair follicle balls, block the digestive tract, and cause the death of the lambs.
5, build a small circle of isolation. Keep the lean, sick, ewes that don’t have lambs alone; prepare preventive medicines, and treat the sick sheep as soon as possible.
Under insufficient pasture conditions, it is necessary to carefully raise and manage and strengthen various management measures to prevent the ewes from falling out. Only in this way can the survival rate of the lambs be guaranteed.
There are mainly the following parts: 1. Sampling swab with disposable sterile plastic rod/rayon head 2. Sterile sampling tube containing 3ml of virus maintenance solution (gentamicin and amphotericin B are selected to better inhibit the fungus in the sample. Avoid the human sensitization reaction that may be caused by penicillin in the traditional sampling solution.) In addition, there are additional parts such as a tongue depressor, a biosafety bag, etc. Intended to use 1. It is used for monitoring and sampling of infectious pathogenic microorganisms by disease control departments and clinical departments. It is suitable for sampling of influenza virus (common influenza, highly pathogenic avian influenza, H1N1 influenza virus, etc.), hand, foot and mouth virus and other types of viruses. It is also used for sampling of Mycoplasma, Chlamydia, Ureaplasma, etc. 2. It is used to transport nasopharyngeal swab samples or tissue samples from specific parts from the sampling site to the testing laboratory for PCR extraction and testing. 3. It is used to preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture. The virus sampling tubes are loaded with infectious substances, and some are even highly pathogenic substances. Therefore, the requirements for packaging containers are very strict, and three requirements must be met at the same time: 1. The safety of transportation. Ensure that the sample does not leak during transportation. Sampling tubes that comply with WHO regulations and biosafety regulations. 2. The security of preservation. Ensure that the sample does not leak during storage. Sampling tubes that comply with WHO regulations and biosafety regulations. 3. The validity of the sample. Make sure that the sampling tube itself will not have a toxic effect on the sample.
