Effects of dietary vitamin A intake on acrosin- and plasminogen-activator activity of ram spermatozoa
Zervos, I. A.; Tsantarliotou, M. P.; Vatzias, G.; Goulas, P.; Kokolis, N. A.; Taitzoglou, I. A. (2005)Acrosin and plasminogen activators are proteolytic enzymes of ram spermatozoa that play an essential role in the induction of the acrosome reaction, as well as the binding of spermatozoa to the oocyte and their penetration ... -
Feed supplemented with byproducts from olive oil mill wastewater processing increases antioxidant capacity in broiler chickens
Gerasopoulos, K.; Stagos, D.; Kokkas, S.; Petrotos, K.; Kantas, D.; Goulas, P.; Kouretas, D. (2015)In the present study, a ceramic membrane microfiltration method was used for the separation of two liquid products, the downstream permeate and the upstream retentate, from olive mill wastewater (OMWW). These liquid products ... -
Luteal stage dependence of pituitary response to gonadotrophin-releasing hormone in cyclic dairy ewes subjected to synchronisation of ovulation
Amiridis, G. S.; Valasi, I.; Menegatos, I.; Rekkas, C.; Goulas, P.; Papanikolaou, T.; Deligiannis, C. (2005)Possible hormonal aberrations precluding conception or maintenance of pregnancy in dairy ewes subjected to ovulation synchronisation were investigated in this study. The pituitary response to exogenous gonadotrophin-releasing ... -
Oocyte pick-up in juvenile lambs affects neither onset of puberty nor their future fertility
Valasi, I.; Menegatos, I.; Papanikolaou, Th; Goulas, P.; Amiridis, G. S. (2006)A study was designed to evaluate whether the time of onset of puberty and fertility of young ewe lambs would be affected by oocyte pick-up conducted in single or repeated sessions during the first months of lambs' live. ... -
Synchronization of ovulation and fixed time intrauterine insemination in ewes
Deligiannis, C.; Valasi, I.; Rekkas, C. A.; Goulas, P.; Theodosiadou, E.; Lainas, T.; Amiridis, G. S. (2005)A novel method for oestrus-ovulation synchronization in sheep followed by fixed time insemination is presented herewith. Mature dry ewes (n = 28) of Karagouniko breed being at an unknown stage of the oestrous cycle, were ...
