"The experiment was established to study the feeding of organic and inorganic forms of zinc and the effect of these zinc forms on the reproductive indicators (ejaculate volume, concentration of sperms and percentage of pathologic sperms in ejaculate) in breeding boars. The experiment included sixty-six boars, which were divided into two equable groups by age and breeds. In 115 days of experiment duration, the volume of ejaculate increased in both groups. Boars receiving the organic zinc form showed a highly significantly increased (P < 0.001) average volume of ejaculate from 207.5 +- 66.56 ml to 289.5 +- 81.28 ml. Boars receiving the inorganic zinc form exhibited the volume of ejaculate increased by 59.52 ml (P < 0.05) in the last two weeks of the experiment while the average volume in the initial sampling was 229.62 +- 102.64 ml. The concentration of sperms in the group receiving the organically fixed zinc slightly decreased from 407.44 +- 126 thous./mm3 to 400.67 +- 200.86 thous./mm3. By contrast, the group of boars whose feeding mixture contained the inorganic form of zinc reached in the last two weeks of the experiment an increased concentration of sperms from 402.63 +- 180.26 thous./mm3 to 424.10 +- 149.81 thous./mm3. The percentage of pathologic sperms did not show any demonstrable difference between the two groups. Both groups exhibited a mild increase in this indicator. The experimental group with the supplement of organic zinc showed an increase from 10.18 +- 8.46 % to 11.67 +- 7.68 % and the experimental group with the supplement of inorganic zinc showed an increase from 9.4 +- 8.4 % to 9.92 +- 6.68 %. The obtained sperm served to produce under identical conditions on average by 20.97 insemination doses (ID) more from the beginning of the experiment in the group of animals receiving organic zinc form. The group receiving inorganic zinc form exhibited an increase by 20.2 ID. Our experimental results demonstrated that feeding the organic zinc form h" .
