Determination the Changes of Rooster Sperm Quality Induced by Chronic Fluorosis

CAI Zong-bao (Institute of Animal Science and Technology,Southwest University Chongqing 400716,China)  
To ascertain the effect of chronic fluorosis is on rooster sperm quality, chronic fluorosis model of roosters was rebuilt artificially by adding F- to the drinking water. In the 30th, 50th and 70th day from the poison reaching time sperms of each animal were collected and the sperm density, sperm vigour and sperm abnormality rate were determined. As a result, chronic fluorosis may cause the reduction of sperm density and sperm vigour and the raise of sperm abnormality rate. The control group has no discrepancy in different testing time. In the experimental group, sperm density of the 50th and 70th day is lower than 30th day, but there is no statistics discrepancy between the 50th and 70th day; and sperm vigour of the 70th day is lower than the 30th day, but there no statistics discrepancy between the 30th and 50th day as well as the 50th and the 70th day; and the sperm abnormality rate has no statistics discrepancy all the testing time. It shows that rooster chronic fluorosis presents a kind of specific time-effect relation, and the sperm abnormality rate takes on a speciality of relatively independence in the process of chronic fluorosis.
