Combined administration of gonadotropin-releasing hormone, progesterone, and meloxicam is an effective treatment for the repeat-breeder cow
Amiridis, G. S.; Tsiligianni, T.; Dovolou, E.; Rekkas, C.; Vouzaras, D.; Menegatos, I. (2009)In practice, the etiologic treatment of the repeat-breeder cow is nearly infeasible. In this study, we tested the hypothesis that a combined treatment would benefit the conception rate of repeat-breeder cows. The components ... -

Daily supplementation with ghrelin improves in vitro bovine blastocysts formation rate and alters gene expression related to embryo quality
Dovolou, E.; Periquesta, E.; Messinis, I. E.; Tsiligianni, T.; Dafopoulos, K.; Gutierrez-Adan, A.; Amiridis, G. S. (2014)Ghrelin is a gastric peptide having regulatory role in the reproductive system functionality, acting mainly at central level. Because the expression of ghrelin system (ghrelin and its receptor) has been detected in the ... -
