- Abstract
With the objective of determining the production, quality and development of sheep embryos collected during the nonreproductive season under tropical conditions, 12 sheep were assigned to two groups: one as control received flushing with commercial feed (T1; n=6) at a rate of 1 kg daily per animal and an experimental group that received flushing based on Clitoria ternatea (T2; n=6). The two groups received a diet based on chopped Cuban CT-115 grass hay during the whole experiment. The variables of study were number of corpora lutea, state of development, and morphological quality of the embryos collected. The results were analyzed with Wilcoxon's non-parametric range test. All the sheep were subjected to the same protocol for synchronization of estruses, using intravaginal sponges impregnated with 65 mg of medroxyprogesterone acetate (MPA) during 11 consecutive days, and at the same time with a superovulatory treatment of 200 mg of FSHp distributed into eight applications with decreasing doses at intervals of 12 each and with the same induction to ovulation with an injection of 250 UI of equine Chorionic Gonadotropin (eCG) at the moment of withdrawal. The number of corpora lutea recorded was 79±3.53 and 45±4.94 for T1 and T2, respectively, with statistical differences (P<0.05) present between treatments. The number of embryos found was 45±2.1, 27±2.1 for T1 and T2, with statistical differences (P<0.05) between treatments. The transferable embryos in the state of compacted morula and early and expanded blastulas were 50±8.4 and 13±2.12 for T1 and T2 respectively, with differences present (P<0.05). Because of the degree of quality, 26 and 11 good embryos were recorded for T1 and T2, respectively, with differences present (P<0.05). There was a better ovary response in sheep fed with commercial meal compared to sheep fed with Clitoria ternatea, with a clear influence on reproduction.
