Abstract :This study was conducted to determine the effects of omega-3 insert ignore into journalissuearticles values(α-linolenic acid); fatty acid supplementation to donor cow rations on superovulation performance, embryo number and quality, and blood-progesterone levels. The study was carried out with two groups, each consisting of 10 black-and-white breed dairy cows. Control group was fed with the basic ration prepared, and the experimental group was fed with the ration added with omega-3 polyunsaturated fatty acid insert ignore into journalissuearticles values(PUFA); source at a level of 3.82% of the basic ration dry matter insert ignore into journalissuearticles values(DM); for 60 days training period. Thus, each of experimental group’s cow consumed 900 g-day feed additives consisting 149.4 g omega-3 daily. The superovulation protocol was started at the 40th day of feeding period. According to the findings of the study, the difference between the groups in terms of the response to superovulation was found to be insignificant insert ignore into journalissuearticles values(P>0.05);. Similarly, there was no significant difference in blood progesterone levels between the groups insert ignore into journalissuearticles values(P>0.05);. However, the difference between the control group and the experimental group in terms of transferable and non-transferable embryo rates was found to be significantly important insert ignore into journalissuearticles values(P<0.05);. The total number of transferred embryos was determined as 37 in the experimental group and 79 in the control group. The total number of non-transferable embryos was recorded as 78 in the trial group and 43 in the control group. At the end of the study, it was concluded that supplementation to donor cow rations with omega-3 fatty acid sources might have a negative effects on transferrable embryo number and quality.
