Abstract
disadvantages of using sexed semen among dairy producers in terms of outcome and economic efficiency. A questionnaire containing 28 five-choice
Likert scale questions was prepared to test the attitudes of respondents concerning the use of sexed sperm in terms of functional, economic, cognitive
and infrastructural aspects. The respondents were the researchers, consultants and dairy farm employees. The findings indicated that farm employees,
unlike the researchers, believed that sexed sperm was effective in reducing dystocia, and the conception rate was not deleteriously affected in different
climates (P<0.01). Better performance of sex-sorted semen in heifers compared to multiparous cows was significantly confirmed by farm employees
and consultants compared to the researchers (P<0.01). According to the researchers, the use sex- sorted semen is uncommon and hence the use of this
type of sperm has a higher risk (P<0.01). The results of this study indicated that the attitude of employees in large industrial dairy farms is largely
consistent with the scientific facts published in the field of sex-sorted semen, and the disagreement of this
