Abstract
The invention relates to a diary cow uterus flushing liquid formula. The formula comprises, by weight, 0.1-10 parts of acid-base buffering agent, 0.5-15 parts of fungicide, 0.1-10 parts of trehalose,0.01-10 parts of polyvinylpyrrolidone, 0.05-5 parts of polyethylene glycol and 60-90 parts of water. A preparation method comprises the steps that the acid-base buffering agent, the trehalose, polyvinylpyrrolidone, polyethylene glycol and water are mixed according to the dosage of all the ingredients, stirring is conducted for 5-20 min slowly at a constant speed, the pH is adjudged to be 6.5-8.0,subsequently, the fungicide is added and stirred for 3-5 min, and the diary cow uterus flushing liquid is obtained. The dosage ratio of the diary cow uterus flushing liquid prepared through the methodto the water is (10-100):(0-90). The diary cow uterus flushing liquid does not contain antibiotics or materials high in irritation and is easy to degrade and capable of avoiding irritation and carcinogenicity to people and livestock; meanwhile the phenomenon that due to the broad spectrum and long-acting fungicide, the environmental microecology is continuously destroyed is avoided.
Description
technical field [0001] The invention belongs to the technical field of research and development of veterinary health care preparations, and in particular relates to a formula of dairy cow uterine flushing liquid without antibiotic residues, a preparation method and a use method thereof. Background technique [0002] The incidence of cow endometritis is about 20% - 50%, but 60% - 90% of cow infertility is caused by it. Microbial infection, imbalance of body hormone levels, and malnutrition are the main causes of endometritis, especially bacterial infection is a common cause of endometritis. Uterine flushing is the main method to prevent and treat endometritis in dairy cows. At present, it is mainly used to perfuse broad-spectrum antibacterial drugs and disinfectants, such as tetracycline, cephalosporin antibiotics and sulfa drugs, 0.1% potassium permanganate, 0.1% Revnu Diol, 0.05% chlorhexidine, 0.05% bromogeramine and other solutions, the flushing volume is generally 30--3...
