چکیده
The objective of this study was to evaluate the effects injectable selenium, vitamin E and B1 compounds on serum metabolic profile pregnancy rates (PR) during non-breeding season in Merino ewes that were synchronized with progesterone equine chorionic gonadotrophin (eCG). Thermographic monitoring last day synchronization successful early selection be used artificial insemination its relationship outcomes. Cyclic non-pregnant (n=75) randomly assigned treatment (n=30) control (n=45) groups. All animals using PGF2α at 0, impregnated intravaginal sponges for 14 days, eCG 48 h before sponge withdrawal carried out 43–45 after removal. Animals group administered (intramuscularly) 1 mg sodium selenite, 60 40 two occasions, beginning insertion following Blood samples collected Perianal perivulvar areas considered thermal pattern 0 a thermo camera. Overall, 90.6% exhibited estrus response protocol. Ewes showed greater PR as compared (70.3% vs 56%). Perivulvar temperature influenced by time only. At removal, temperatures significantly lower pregnant than animals. In conclusion, increased protocol thermographic evaluation performed could very prediction pregnancy.
