Diagnosis and treatment of wool-eating disease of sheep in house feeding

In the spring of 2004, sheep in some villages in the suburbs of our county gnawed each other on body wool. The quality of diseased wool was destroyed, indigestion, anemia, weight loss, serious death of sheep, and great losses to the industry. According to the basic morbidity, feed analysis, clinical symptoms, treatment, diagnosis of nutritional and metabolic diseases, through the adoption of comprehensive prevention and control measures, the disease was controlled, and the report is as follows:

1 basic morbidity

The sick sheep are mainly shed-fed sheep, less in half-house feeding, less in adult sheep, more in lambs, less in farmers with more forage varieties, more in farmers with a single breed, destruction of wool quality and death in individual sheeps. treatment with anti-ectoparasite drugs is ineffective.

2 clinical symptoms

Sick sheep depressed spirit, loss of appetite, pale conjunctiva, licking wall soil, chasing each other to bite body hair, hair loss, severe abdomen, tail hair removal, rumen swelling, constipation. He died of stretching, severe cachexia or secret knot of stomach flap.

3Feed analysis

3.1 most of the diseased sheep were fed in houses, with single forage, mainly crop straw and lack of green fodder.

3.2 under the condition of house feeding, there is a lack of trace elements and minerals in forage.

3.3 the concentrate is mainly corn and lack of protein.

3.4 Salt is deficient in some feeds.

4 treatment

4.1 conditional supply of full-price feed, such as preparation of feed concentrate.

4.2 add 0.5% salt to the feed.

4.3 calcium dihydrogen phosphate as the main mineral additive was added to the feed.

4.4 add feed yeast powder or Hu cake to the feed.

4.5 add green feed or multivitamins.

5 experience

5.1 when raising sheep in house feeding, due to the limitation of conditions, farmers mainly use crop straw or grain seeds, the forage is single and the nutrition is not complete, so it is suggested that the full price material should be supplied conditionally.

5.2 in feed coordination, attention should be paid to the supply of mineral additives and vitamins. Lambs have weak rumen function, poor ability to synthesize vitamins, and easy to lack vitamins.

5.3 in order to increase the palatability of feed and supplement CL and Na, 0.5% salt is recommended.

5.4 pay attention to keep the balance of calcium and phosphorus ratio in formula feed, which is generally kept at 2-1.3 ∶ 1.

5.5 A certain proportion of protein should be added to the feed to prevent the lack of protein from hindering the growth of wool.

5.6 appropriately increase the exercise of house feeding to promote metabolism.

5.7 regularly deworming sheep, especially external parasites.
