Valasi, I.; Fthenakis, G. C.; Prassinos, N. N.; Menegatos, I.; Grigoropoulou, V.; Deligiannis, C.; Vainas, E.; Amiridis, G. S. (2009)

The effects of follicular aspiration for oocyte retrieval on the attainment of puberty and growth rate were studied in winter-born (9 treated and 6 control) and autumn-born (5 treated and 5 control) ewe lambs. In the treated ...

Ultrasonographic findings in the ovine udder during lactogenesis in healthy ewes or ewes with pregnancy toxaemia

Barbagianni, M. S.; Gouletsou, P. G.; Valasi, I.; Petridis, I. G.; Giannenas, I.; Fthenakis, G. C. (2015)

Objective of the study was to record, by means of ultrasonographic examination, changes occurring during lactogenesis in the udder of healthy ewes and of ewes with pregnancy toxaemia. The work was carried out in 28 ewes, ...

Pregnancy toxaemia as predisposing factor for development of mastitis in sheep during the immediately post-partum period

Barbagianni, M. S.; Mavrogianni, V. S.; Katsafadou, A. I.; Spanos, S. A.; Tsioli, V.; Galatos, A. D.; Nakou, M.; Valasi, I.; Gouletsou, P. G.; Fthenakis, G. C. (2015)

Objective of the work was to evaluate the potential predisposing role of pregnancy toxaemia in development of mastitis in the immediately post-partum period. Ewes were allocated in subgroups A1 or A2 (with pregnancy toxaemia) ...

Management of pre-pubertal small ruminants: Physiological basis and clinical approach

Valasi, I.; Chadio, S.; Fthenakis, G. C.; Amiridis, G. S. (2012)

Puberty is a gradual process, during which animal reproductive competence is attained with respect to physiology, morphology and behaviour. Onset of puberty in small ruminants differs between sexes, due to early sexual ...

Endocrinological profile and follicular development in cyclic ewes subjected to repeated ovum pick-up

Valasi, I.; Theodosiadou, E.; Fthenakis, G. C.; Papanikolaou, T.; Deligiannis, C.; Kalogiannis, D.; Chadio, S.; Amiridis, G. S. (2013)

Blood concentrations of progesterone, FSH and oestradiol in Karagouniko ewes subjected to laparoscopic ovum pick-up (OPU) at specific stages of induced oestrous cycle, were measured. Twenty-four cyclic ewes were randomly ...

Ultrasonographic findings in the ovine udder during involution

Petridis, I. G.; Gouletsou, P. G.; Barbagianni, M. S.; Amiridis, G. S.; Brozos, C.; Valasi, I.; Fthenakis, G. C. (2014)

The objective of the study was to record, by means of ultrasonographic examination, changes occurring in the udder of ewes during involution and to compare differences between progressive or abrupt udder drying-off. In ...

Administration of a long-acting antiparasitic to pre-pubertal ewe-lambs in Greece results in earlier reproductive activity and improved reproductive performance

Mavrogianni, V. S.; Papadopoulos, E.; Fragkou, I. A.; Gougoulis, D. A.; Valasi, I.; Orfanou, D. C.; Ptochos, S.; Gallidis, E.; Fthenakis, G. C. (2011)
