Dietary supplementation with sesame seeds to improve semen quality of ho cocks

High levels of polyunsaturated fatty acids in chicken spermatozoa make them susceptible to lipoperoxidation and reduce their fertility. This study was conducted to assess the effect of sesame seed suplementation in the diet on the semen quality of Ho cocks. Eighteen 13-14 month-old cocks were randomly divided into three groups and were assigned to one of the following treatments: 0% SS (control), 5% SS, or 7% sesame seeds per kg of diet for ten consecutive weeks after a two-week adaptation period. Semen characteristics were evaluated once a week.
