Rumen food accumulation is also called acute rumen dilatation. Mainly due to improper feeding, cattle eat a lot of coarse, inferior and indigestible feed, such as wheat straw, bean straw, corn straw, peanut seedling and sweet potato seedling. Or eat a lot of delicious and expandable forage. Sometimes it can be secondary to gastric achalasia, traumatic reticular gastritis, gastric flap obstruction, abomasum displacement and other diseases.

Clinically, the main manifestations of sick cattle are loss of appetite or abandonment of food, reduction or cessation of rumination and belching. The nose mirror is dry. Mild abdominal pain, arched back and waist, hind legs kicking abdomen, moaning and wagging tail, and swelling of lower abdomen. Touching the rumen, the sick cow is in pain. Rumen contents are sticky or hard, and there is a voiced sound on percussion. Rumen peristalsis sounds increased in the early stage of auscultation, then weakened or disappeared.

preventive measure

Strengthen feeding management, prevent overeating and actively treat the primary disease; Avoid sudden refueling, and feed roughage after proper processing and softening.

therapeutic method

(1) Mild patients can massage the rumen 10 ~ 20 minutes at a time, 1 ~ 2 hours at a time. If you massage with plenty of warm water, the effect will be better. You can also take 250 ~ 500 grams of yeast powder orally twice a day. For patients with moderate symptoms, laxatives can be taken orally, such as 500-800g of magnesium sulfate or sodium sulfate, 30-40ml of turpentine and 5-8L of ordinary water once. Or liquid paraffin 1 ~ 2 liters, taken orally once; Or salt laxatives and oil laxatives are used together.

(2) Gastric lavage: When general therapy fails, gastric lavage can be repeated with a thick gastric tube to export rumen contents as much as possible.

(3) When the rumen contents are diarrhea, drugs that stimulate rumen peristalsis can be used, such as neostigmine, physostigmine, pilocarpine, etc. If you have a bad appetite, you can use stomach-invigorating drugs as appropriate, such as15 ~ 20ml of Momordica cochinchinensis tincture, 50 ~ 80ml of Gentiana scabra tincture and 500ml of water, once orally.

(4) When the sick cows have poor appetite and obvious dehydration, they should be supplemented with water intravenously, such as 500 ~ 1000 ml of 25% glucose solution, 2000 ~ 3000 ml of compound sodium chloride solution or 5% sugar saline, and 500 ~ 1000 ml of 5% sodium bicarbonate solution. , and one-time intravenous injection.

(5) For serious and stubborn rumen food accumulation, when the application of drugs is ineffective, rumen incision can be performed to remove rumen contents.
