Prevention and Control Methods and Technical Key Points for Lamb Dysentery
Lamb Dysentery
(Agricultural Wealth Network) [Characteristics]
This disease mainly affects newborn lambs within 7 days of age and is an acute toxemia caused by Clostridium perfringens. In addition, Salmonella, Escherichia coli and Streptococcus can also cause the disease, manifesting as persistent diarrhea, commonly known as "scouring", "white diarrhea" and "bloody diarrhea", which can often cause mass death of lambs. When there is a sudden climate change, uneven feeding, or umbilical cord trauma, lambs are susceptible to infection.
[Prevention and Control]
1. Strengthen epidemic prevention. At 20-30 days and 10-20 days before the due date of pregnant ewes, inject 2-3 ml of lamb dysentery formalin vaccine twice; the injection sites are respectively the subcutaneous tissue on the inner side of both hind legs. This can enable newborn lambs to obtain passive immunity.
2. For affected lambs, administer 0.3 g of oxytetracycline and 0.3 g of pepsin by drenching, 2 times/day.
3. Sulfaguanidine 0.5 g, tannalbin, bismuth subnitrate and baking soda 0.2 g each, administered by drenching at one time, 3 times/day.
4. Chloramphenicol 0.02-0.03 g per kg body weight, intramuscular injection 2 times daily or drenching at 3 times the amount.
5. For dehydrated lambs, fluid replacement 1-2 times daily, with oral rehydration salts or intravenous injection of 20-100 ml of 5% glucose saline
