Report on diagnosis and treatment of abomasum accumulation in Dairy cows

Abomasum accumulation in dairy cows is a disease caused by abomasum relaxation, retention of contents and dilatation of stomach wall due to vagus nerve regulation disorder. With the development of the local dairy industry, the occurrence of abomasum in dairy cows has increased, and it is often seen in the perinatal period of dairy cows (before and after delivery). If it is mistreated or mistreated, it will often lead to the death of both mother and child and cause great economic losses to dairy farmers. Early detection, early diagnosis and early treatment can improve the curative effect. If the opportunity is delayed, it is quite difficult to cause gastritis. In the past two years, the author diagnosed and treated 11 cases of the disease and cured 9 cases (including 2 cases died of secondary abomasum gastritis and peritonitis complicated with pericarditis), with a cure rate of 81.7%.

1 cause of the disease

1.1 due to poor feeding and management, feeding a large amount of coarse and cellulose-rich wheat straw, corn stalk, peanut vine, rice straw, etc., mixed with crushed corn stalk, soybean meal, peanut cake, cottonseed cake and other refined feed, coupled with insufficient drinking water, or unclean feed, mixed with mud and sand, cement dregs, wood chips, chemical fiber articles, plastic film, etc. mixed with feed, accidental ingestion can lead to varying degrees of obstruction of the forestomach. Abomasum digestive dysfunction, metabolic disorders occur abomasum accumulated food.

1.2 in the later stage of pregnancy, the fetus develops rapidly and oppresses the stomach and intestines, which directly affects the vagus nerve function, resulting in the inhibition of gastrointestinal digestion function, or after the cow gives birth to a calf, the abdomen is empty, the uterus begins to contract, and labor pains continue to occur. at this time, the functional activities of the digestive system have not yet been restored, and breeders are eager to replenish and increase concentrate, resulting in the occurrence of abomasum accumulation.

1.3 abomasum accumulation can also be secondary to other diseases such as forestomach relaxation, rumen accumulation, traumatic reticulitis, peritonitis, small intestinal secret knot, liver and spleen abscess and so on. Secondary diseases, complex conditions and high mortality.

2 clinical symptoms

Suffering from the cow spirit is depressed, the coat is rough, the nose is dry, the body temperature is basically normal, the appetite is lost, the ruminant stops, the abdomen is enlarged, the rumen content is full of and accumulates fluid, the defecation posture often appears, the feces are dry, sometimes the brown paste feces are discharged, the urine is less, yellow and smelly, the mouth color is yellow and white, the tongue root is dark red, the oral fluid is sticky, sour and smelly, and the pulse is heavy.

3 main points of diagnosis

In the early stage of the disease, the affected cattle have loss of appetite, reduced or stopped ruminating and like to drink water. Auscultation showed decreased rumen peristaltic sound, dry feces and yellow urine, with clinical symptoms of relaxation of the forestomach. With the development of the disease, a large amount of rumen fluid was accumulated in the rumen, the abdominal circumference increased, and the vibrating sound was shown by hand impact palpation. At the same time, the obvious steel pipe sound could be heard at the left countdown 1 / 5 ribs or the right 1 / 2 ribs with your hand, and you could often lie on the ground seriously, drooling, looking back at the abdomen, and kicking the abdomen. The lower part of the right abdomen is swollen and the lower part of the posterior edge of the rib arch is pressed firmly. The contents of abomasum puncture were pH 1-4. Rectal examination: there is a small amount of brown paste in the rectum.

4 methods of treatment

4.1 traditional Chinese medicine takes eliminating accumulation and guiding stagnation, moistening dryness and purging stool as the treatment principle.

Methods to add and subtract Angelica Cistanche decoction: Angelica sinensis 200g, sesame oil 250g, Cistanche deserticola 100g, Senna leaf 60g, wood incense 45g, Magnolia officinalis 60g, fried Fructus Aurantii 60g, Rhizoma Akebia 45g, Hawthorn 120g, Jianqu 120g, hemp seed 150g, Yu Li kernel 100g, trigonous 60g, zedoary 60g, fried laisan 150g, ginger 120g.

4.2 Western medicine mainly focuses on strengthening heart and replenishing fluid, detoxification and anti-inflammation.

Compound sodium chloride injection 2000 ml,5% glucose saline 2000 ml,10% Annaka 30 ml, gentamicin 80 ~ 1 million u, intravenous injection, vitamin C 30 ml, intramuscular injection.

4.3 electroacupuncture therapy

One electroacupuncture machine (or acupuncture electroanaesthesia apparatus) and two round needles (12 cm) for animals were punctured into Jianwei acupoint and Weishu acupoint respectively, connecting wires, turning on the electroacupuncture machine switch, using low frequency microwave (60-80 beats per minute, without mild stimulation of needle sensation), each electrotherapy for 25 min,3~5 days as a course of treatment. Strengthen nursing, fasting for 3 days after medication, only for clean warm water, free drinking, especially forbidden to feed concentrate, exercise properly. After 3 days, if you have discharged a large amount of dung and regurgitated, you can feed a small amount of hay, Millet Congee and so on.

5 typical cases

Case 1 6-year-old black and white dairy cow raised by Ni Wanquan in Jingang Township, Wolong District, Nanyang City. Main complaint: after calving, due to postpartum physical weakness, the cow increased the amount of concentrate feed (cornmeal, soybean meal, peanut cake, cottonseed cake). The daily feeding amount was about 4 kg. After feeding, the cow began to bloat and did not eat. It was invalid by the local veterinarian. Clinical examination: depressed spirit, slightly distended abdomen, solid upper and lower deficiency, increased respiration, rapid heartbeat, 86 / min, auscultation rumen, weak peristaltic sound of valvular and abomasum, obvious steel pipe sound at the last rib on percussion, pH of abomasum puncture content 4, less dry feces, black color, less yellow urine, sticky mouth fluid, heavy pulse. Take the traditional Chinese medicine Danggui Cistanche decoction (as above), 1 dose / day, 2 doses in a row. The western medicine prescription combined with infusion is the same as before. Electroacupuncture at Jianwei acupoint and Weishu acupoint for 30 min,1 / day. Black-brown feces were discharged on the third day, smelly, drank a lot of warm water, began to regurgitate on the third day, began to feed a small amount of hay on the fourth day, and basically recovered on the seventh day.

6 Summary

6.1 Danggui Cistanche decoction originated from the second episode of Chinese Veterinary diagnosis and treatment experience, which is for Mr. Pei Yaoqing. The appropriate addition and subtraction of this prescription is the original prescription to remove wheat, Tongcao, Jiaotong, Hawthorn, tangerine peel, hemp kernel, plum kernel, trigonous, zedoary, semen Raphani, ginger. Efficacy: moisturize dryness and relieve defecation, eliminate accumulation and guide stagnation. Indications: the secret knot of old and weak, pregnant, postpartum and frail animals. In the prescription, Angelica (deep-fried) moistening dryness and smooth intestine; Cistanche deserticola warming kidney and invigorating yang, moistening intestines and laxative are the main drugs; Senna leaves clear heat and purge Huotong as auxiliary drugs; wood incense, incense, Magnolia officinalis, tangerine peel, Fructus Aurantii and Fructus Aurantii are used as adjuvants; Hawthorn, Jianqu, semen Raphani, SanLeng and zedoary are used as adjuvants to help the main medicine to eliminate accumulation and guide stagnation; Mutong regulates waterways, clearing heat and diuresis; ginger is introduced. The combination of various medicines, moisturizing and dryness knot, pushing Chen Zhixin, combining strength and softness, tonifying and reducing opening and closing, mysterious mechanism.

6.2 in order to improve the regulation of the central nervous system, enhance the functional activity of the heart, improve gastrointestinal function, and prevent the occurrence of systemic dehydration and self-poisoning, therefore, intravenous injection of compound sodium chloride injection, glucose saline, Annaka injection, antibiotics, vitamin C and so on to enhance the recovery of autologous function and prevent secondary infection.

6.3 electroacupuncture therapy, using microwave at low frequency (to avoid mild stimulation of needle sensation), each electrotherapy for 20 to 30 min, this appropriate current stimulation can excite the vagus nerve trunk. The dorsal branch of the vagus nerve mainly dominates the functional activity of the forestomach, while the ventral branch of the vagus nerve dominates the anterior stomach and abomasum. Therefore, it can reflexively regulate the functional activity of abomasum and the relaxation of pyloric sphincter, enhance gastrointestinal peristalsis, promote accumulated food to move backward, and promote fecal excretion.
