The effect of experimentally induced subclinical mastitis on the milk yield of dairy ewes
Saratsis, P.; Alexopoulos, C.; Tzora, A.; Fthenakis, G. C. (1999)In each of the two experiments, subclinical mastitis was induced by inoculating both mammary glands of Karagouniko and of Chios-cross ewes with a Staphylococcus epidermidis. After inoculation, the somatic cell counts of ... -

(2005)The objectives of the work described in this paper were: (i) to study the outcome of challenging ewes with Mannheimia haemolytica, at different sites of their teats, (ii) to compare the effects of two different isolates ... -
Incidence risk and aetiology of mammary abnormalities in dry ewes in 10 flocks in Southern Greece
Saratsis, P.; Leontides, L.; Tzora, A.; Alexopoulos, C.; Fthenakis, G. C. (1998)In a field investigation of 10 flocks in Southern Greece, 3367 dairy ewes were examined twice, in order to estimate the incidence risk and the aetiology of mammary abnormalities during the dry-period. Abnormal secretion, ... -
Incidence risk and clinical features of retention of foetal membranes in ewes in 28 flocks in southern Greece
Fthenakis, G. C.; Leontides, L. S.; Amiridis, G. S.; Saratsis, P. (2000)In a field investigation of 28 flocks in southern Greece, 7660 lambings were monitored. Retention of foetal membranes (defined as failure to expel the foetal membranes within 6 h of lambing the last lamb) was recorded in ... -
