In the production of sheep, there are often some ewes who produce 2 to 3 lambs or a ewes produce less milk after lambing and are not enough for lambs to eat; some ewes die after lambing and leave solitary lambs. The ewes who find milk for the lambs are the “nanny†sheep.
The "nanny" sheep is best to choose a ewes whose postpartum lambs have died and enough milk as nannies. This option can prevent mutton from causing mastitis due to breast swelling. In addition, ewes that produce single lambs but have high lactation performance can be selected as nanny sheep.
When choosing “nanny sheepâ€, it should be noted that the number of lambs born after the date of sending the lambs to be nursed is as close as possible to the number of lambs born to the “baby sheepâ€, preferably not exceeding three days before and after. When the “Baby Sheep†recognizes their lambs by the smell of the lambs, and does not allow the surrogate lambs to eat their own milk, the nanny or udder of the nanny can be coated on the surrogate lamb in advance, or on behalf of the mother. The lambs born to lambs and nannies are all smeared with the same odor at the same time, for example, Sulai children, so that the nanny sheep does not identify its own lamb. In addition, strong lambs should be selected for delivery among the lambs of one lamb and the weak lambs should be left to feed their ewes. Generally, the lambs should be eaten by the ewe's colostrum and then sent to the “nanny sheepâ€, which will help increase the disease resistance of the lamb.
Fluorine-Containing Methylbenzene products can be used as herbicides in the manufacture controlling wheat fields, cotton fields and other broadleaf weeds and perennial weeds. It can also be used in the manufacture of antipsychotics drugs.
The Fluorine-Containing Methylbenzene products must be kept under seal, once exposed to light will immediately cause discoloration. It should also be stored in a cool, ventilated warehouse, away from fire and heat. Compartment temperature should not exceed 30 ℃. And make the appropriate technical measures for fire and explosion. Products will Decomposition by high fever and emit toxic gases, such as carbon monoxide, carbon dioxide, hydrogen fluorid. Due to ts vapor is heavier than air, it can spread from low place to far away places. In case of fire conditions, should not fire with water. In case of a small amount of leakage should be evenly sprayed with dilute hydrochloric acid. In case of large spills should build a causeway or trenching asylum. The transfer pump to tankers or exclusive collector, recycling or shipped to the waste disposal sites.
