Bacteriological and epidemiological findings during examination of the uterine content of ewes with retention of fetal membranes
(2002)We included 92 pairs of ewes with or without retention of fetal membranes in a cohort study of 25 flocks in Southern Greece. We obtained two uterine content samples under aseptic conditions, by introducing a swab into the ... -
A Bayesian Weibull survival model for time to infection data measured with delay
(2010)Survival analysis methods can be used to identify factors associated with the time to induction of infection In the absence of a perfect test, detection of infection is generally delayed and depends on the duration of the ... -
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 ... -
Effect of health disorders on the hazard of culling on the first or second lactation in Iranian dairy herds
(2013)We conducted a longitudinal retrospective study in order to assess the effect of health disorders (HDs) on culling in the 1st or 2nd lactation cows, in Iranian dairy herds. In total, 7067 first- and second-parity Holstein ... -
Effect of long-term dietary supplementation with clinoptilolite on performance and selected serum biochemical values in dairy goats
(2009)Objective-To determine the effect of dietary supplementation with clinoptilolite on health and production as well as serum concentrations of fat-soluble vitamins, macroelements and trace elements, and activities of hepatic ... -
Effects of aflatoxin B1 administration on Greek indigenous goats' milk
(2012)Aflatoxins are toxic metabolites of the fungi Aspergillus spp. After aflatoxin B1 (AFB1) is consumed by lactating animals, it is metabolized to aflatoxin M1 (AFM1), which is excreted into the milk. The present study ... -
Effects of essential oils on milk production, milk composition, and rumen microbiota in Chios dairy ewes
(2011)The effect of the addition of an essential oil (EO) preparation (containing a mixture of natural and nature-identical EO) on the performance of dairy ewes of the Chios breed was investigated. Eighty lactating ewes were ... -
Effects of retention of fetal membranes on subsequent reproductive performance of dairy ewes
(2004)Seventy-one pairs of ewes with or without retention of fetal membranes in the previous lambing season, were included in a cohort study of 25 flocks in southern Greece; in 27 pairs regulation of the breeding cycle was ... -
Experimentally induced teat stenosis in dairy ewes: Clinical, pathological and ultrasonographic features
(2004)A strain of Staphylococcus chromogenes was introduced into the teat cistern of five ewes, teat inflammation and stenosis being the primary consequences. Initially, the inoculated teats were swollen and warm; later, a hard ... -
Foot lameness in dairy goats
(2009)An outbreak of foot lameness in a dairy herd of 170 goats is described. The herd, that was kept mostly indoors, was attended between December 2006 and November 2007. During this period, 15% of the goats showed lameness ... -
Influence of oestrus on the heat stability and other characteristics of milk from dairy goats
(2008)We examined the heat stability, somatic cell count (SCC), pH, fat, protein and lactose content of milk from goats during the oestrous period, in order to investigate evidence of possible oestrus effects on milk physical ... -
Isolation of Arcanobacterium pyogenes from the scrotal skin and the prepuce of healthy rams or from rams with testicular abnormalities
(2006)In a field study, samples were obtained from the scrotal skin and the preputial cavity of 48 rains and examined bacteriologically. Bacteria were isolated from all skin samples and from 90% of preputial cavity samples. The ... -
A matched case-control study of factors associated with retention of fetal membranes in dairy ewes in Southern Greece
(2000)We defined retention of fetal membranes (RFM) in dairy ewes as failure to expel the placenta within 6 h after lambing the last lamb and designed a matched case-control study to identify factors that affect the risk of ... -

Progesterone concentration as an indicator of ovarian response to superovulation in Chios ewes
(2002)We investigated the prediction of the ovarian response to superovulation using progesterone (P-4) determination in Chios ewes. During the estrus period, estrus synchronization and multiple ovulations were induced in 100 ... -
