What are the common methods for preventing and treating diseases in sheep raised in spring?
Acute bloat: Because sheep are fed hay for a long time during winter housing, they are prone to overeating when they occasionally eat green grass in spring. The green grass ferments acutely in the stomach, producing a large amount of gas, which expands the rumen. If rescue is not timely or the rescue method is improper, it can cause the sheep to die. Rescue method: insert a section of willow stick into the sheep's mouth, tie both ends with rope to the sheep's head, let the sheep chew, and at the same time massage its left flank with your hand to help release the gas. You can also peel the paper off 5~10 cigarettes, divide the tobacco shreds into two portions and stuff them into the sheep's mouth; mild cases recover 1 hour after eating. You can also use
