Long-term and systematic exploration and research have been carried out on a strange disease commonly known as "long tooth disease" by farmers and herdsmen, which is still widely prevalent in Baotou and its adjacent areas and harms the health of nearly one million livestock, and more than a dozen scientific research projects have been undertaken. The etiology of chronic fluorosis was identified through the investigation of incidence regularity, clinical examination, autopsy, laboratory examination, X-ray and man-made diseases. Through the disease scope and hazard procedure, the background pollution of the first pollution source was excluded, and the pathogen was found to be industrial fluorine pollution in Baotou City. The sheep fluorosis model was successfully reproduced, and valuable data such as poisoning dose, time, dangerous age and X-ray characteristics were obtained. In order to treat the teeth of sick sheep, a set of 12 small animal dental instruments was developed, which filled a gap in veterinary instruments. Experiments show that field grazing and drug treatment are effective control measures. The fluorosis research he presided over won 4 second and third prizes of provincial and ministerial level scientific and technological progress and 3 third prizes of municipal scientific and technological progress. In recent years, he presided over the introduction of oil seedlings to prevent and control Newcastle disease and won the second prize of municipal promotion, and the scientific research project of "rapid diagnosis of Newcastle disease" won the third prize of municipal scientific and technological progress; He presided over the construction of 200,000 specialized villages for laying hens and the promotion project of "Four Good and Four Reforms" for 50,000 pigs, which increased farmers' income by 9.2 million yuan and won the second prize of harvest in the autonomous region and the first prize of harvest at the municipal level. He has written and published more than 20 academic papers such as "Investigation Report on Dental Diseases of Livestock in Baotou Area".
