Prevention and treatment of wool-eating disease in lambs fed in a house to block the intestinal tract

Wool-eating disease mainly occurs in lambs fed in winter and spring. Because the lamb eats too much wool, in addition to affecting digestion, in serious cases, it can cause intestinal obstruction caused by eating hair ball and die.

Lamb

1 cause of disease:

First, the lack of minerals and vitamins in the diets of ewes and lambs, especially the lack or imbalance of calcium and phosphorus, lead to disorders of mineral metabolism.

Second, the wool of lambs during lactation grows very fast and requires a large amount of sulfur-rich proteins or amino acids needed to grow wool. If this kind of protein is insufficient, it will cause lambs to eat wool.

Third, after weaning, the grazing time of the lamb is short, and the supplementary feeding is not timely. When the lamb is hungry, it feeds on feed mixed with wool and forage grass.

Fourth, the dirty hairs around the breasts, nipples and legs of the delivery ewes are not cut off, and the newborn lambs mistakenly ingest the wool while sucking.

Fifth, in house feeding, the density of lambs is too high, gnawing on each other's wool, into the intestinal tract, leading to the disease.

2Clinical symptoms:

In the early stage of the disease, the lambs gnawed and ate the wool, especially the contaminated hair on the abdomen, thigh and tail. The lambs gnawed at each other's fur. When the hair ball can block the true stomach and intestines, the lamb shows lying in bed, grinding teeth, digestive dysfunction, constipation, abdominal pain, gastrointestinal dyspnea, and in severe cases, emaciation and anemia. On palpation of the abdomen, lumps of different sizes can be touched in the true stomach, intestines and rumen, and the lambs are in pain and restlessness. Serious illness, untimely treatment, can lead to death.

3Prevention and control measures:

(1) Prevention at ordinary times. Strengthen feeding management, feeding should be regular, quantitative, to prevent lambs from overeating. The lambs were supplemented with feeds rich in protein, vitamins and minerals, especially green fodder, carrots, sugar beets, wheat bran, etc., supplemented with 5 grams of bone meal and proper salt every day. Attention should be paid to the cleanliness of childbirth ewes and sheephouses. After giving birth to the lamb, the ewe cut off the long hair around the breasts, nipples and dirty hairs on the legs, sterilized with 2%-5% Lysu, and then let the lambs suck.

(2) medication. ① was infused with vegetable oil, liquid paraffin, artificial salt and sodium bicarbonate. If ② has diarrhea symptoms, cardiotonic fluid replacement should be performed. Intramuscular injection of sodium camphor sulfonate or sodium an 5-10 ml, twice a day. Use 500 ml of 5% sugar saline and 200 ml of 25% glucose for intravenous injection, once a day. When there are symptoms of acidosis, 200ml 300ml sodium bicarbonate injection can be given each time. Once a day. ③ for every 5 lambs, feed 1 egg or 2 eggs a day, mash the eggshell, mix it into the feed or put it into the milk. Feeding for 5 days, stopping for 5 days, and feeding for another 5 days can control hair eating disease. ④ with 40 parts of salt, 25 parts of bone, 35 parts of calcium carbonate, fully mixed, mixed with a small amount of wheat bran, placed in the trough and allowed the lambs to lick freely. ⑤ supplements vitamin A, D and trace elements to thin lambs, especially those that lick the wool. If ⑥ is seriously ill, the true stomach can be cut open and the hair ball can be removed.
