Administration of antibiotics to ewes at the beginning of the dry- period
(2014)The objective of the present paper is to review the significance of administration of antibiotics at the end of a lactation period/beginning of the dry-period in ewes. During the stage of active involution, there is an ... -
Bacterial flora and risk of infection of the ovine teat duct and mammary gland throughout lactation
(2007)We collected samples of teat duct material and mammary secretion from ewes in three farms (flock A, polyparous n = 7; flock B, polyparous n = 6, primiparous n = 4; flock C, polyparous n = 4): 14 samples immediately after ... -
Consequences of reduced vitamin A administration on mammary health of dairy ewes
(2013)The study was carried out in Mytilene breed dairy ewes, which were allocated into two groups, 2 months before their first mating. All animals were given a diet based on dried alfalfa hay and concentrate compound feed with ... -
Effects of lamb sucking on the bacterial flora of teat duct and mammary gland of ewes
(2008)We aimed (i) to determine differences in bacterial flora of teat duct and mammary gland of ewes before and after suckling, (ii) to evaluate factors potentially affecting those. We collected samples of teat duct material ... -
Patterns of maternal-offspring behaviour of dairy sheep and potential association with mammary health
(2007)Behaviour during lactation and its relationship with mammary health was investigated in 12 dairy ewes (six with single lambs and six with twins) for 42 d after lambing. Behavioural recordings were made. Samples of teat ... -
Presence of sub-epithelial lymphoid tissues in the teat of ewe-lambs and adult ewes
(2007)In the first part of the study, 24 clinically healthy teats from non-lactating ewe-lambs were examined bacteriologically and histologically. No bacteria were isolated from any of these teats; lymphocytes were observed in ... -
Presence of subepithelial lymphoid nodules in the teat of ewes
(2007)A total of 87 clinically healthy ovine teats were examined bacteriologically (by scraping the mucosa) and histologically. Teats examined were those of lactating mammary glands with no bacteria isolated (n = 23); of mammary ... -
Selenium, vitamin E and vitamin A blood concentrations in dairy sheep flocks with increased or low clinical mastitis incidence
(2011)Objective of the study was to evaluate the relationship between blood concentrations of selenium, vitamin E and vitamin A with the incidence of acute clinical mastitis in dairy sheep. For this purpose, 13 flocks with ... -
Trematode infections in pregnant ewes can predispose to mastitis during the subsequent lactation period
(2014)Objective was to investigate if trematode infections predispose ewes to mastitis and/or metritis. We used 80 trematode-infected ewes: primigravidae in group P-A and multigravidae in M-A remained untreated, primigravidae ... -
Ultrasonographic findings in the ovine udder during involution
(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 ...
