[Fructose and the fructolysis index in bull semen].
The fructose content and the fructolysis index were studied in the semen of bulls. It was established that the value of the index depends upon the age. Highest values were found with the semen of 2-year-old bulls (3.23 +/- 0.13), and lowest were the values in bulls aged from 5 to years (2.49 +/- 0.12). It was also found that in September-October the fructolysis index is higher than the values in March-May. No differences were observed with the content of fructose.
