Efficacy of feeding cow colostrum to newborn lambs
(2012)In the present study the efficacy of feeding cow colostrum to newborn lambs was investigated. Seventy two newborn lambs were divided into 6 groups and were fed as follows: groups 1 to 3 received 4 meals of 1st or 2nd or ... -
Efficacy of marbofloxacin against respiratory infections of lambs
(2007)The trial was carried out in a sheep flock with mixed Mannheimia haemolytica/Mycoplasma spp. respiratory infection; 60 lambs were included therein and allocated as follows: lambs in group MH were subcutaneously injected ... -
Endocrinological profile and follicular development in cyclic ewes subjected to repeated ovum pick-up
(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 ... -
Exploring the assumptions underlying genetic variation in host nematode resistance (Open Access Publication)
(2008)The wide range of genetic parameter estimates for production traits and nematode resistance in sheep obtained from field studies gives rise to much speculation. Using a mathematical model describing host - parasite ... -
Flock-level factors associated with the risk of Mycobacterium avium subsp paratuberculosis (MAP) infection in Greek dairy goat flocks
(2014)In this cross-sectional study we identified flock-level risk factors for Mycobacterium avium subsp. paratuberculosis (MAP) infection, in Greek dairy goat flocks. We collected 1599 milk samples from does that were at the ... -
Health management of ewes during pregnancy
(2012)The objectives of health management of ewes during pregnancy are as follows: (i) successful completion of pregnancy at term, (ii) birth of healthy and viable lambs, with optimal birth and potential weaning bodyweight, (iii) ... -
Histological Features in the Mammary Glands of Female Dogs throughout Lactation
(2010)> The objective of this study was to describe the histology of the mammary glands of female dogs throughout lactation. Twelve lactating female dogs were operated 4, 7, 10, 14, 21, 28, 35, 42, 56, 70 and 84 days post-partum; ... -
Histopathological and immunohistochemical features of natural goat scrapie
(2006)Histopathological and immunohistochemical examinations were performed on the brain and spinal cord of 37 goats from two Greek herds in which scrapie had been reported. Of the 37 animals, 18 were from a herd consisting only ... -
Immunonutrition: Nutritional control of parasites
(2006)Whilst it has long been known that improved protein nutrition can increase resilience, i.e. reduce the consequences of subclinical gastrointestinal nematode parasitism on sheep performance, improved protein nutrition can ... -
In silico exploration of the effects of host genotype and nutrition on the genetic parameters of lambs challenged with gastrointestinal parasites
(2007)An in silico mathematical model was used to explore the effect of, and the interaction between, (i) nutrition, (ii) genotype for growth and (iii) genotype for resistance, on the estimates of genetic parameters for resistance ... -
Incidence risk and aetiology of mammary abnormalities in dry ewes in 10 flocks in Southern Greece
(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, ... -
Leptospirosis: An important re-emerging infection of animals and man
(2010)Leptospirosis, a re-emerging infection of animals and man, is caused by one of 200 serotypes of Leptospira spp. The genus is currently divided into eight pathogenic species, infecting various animal species and man, either ... -
Maedi-Visna: Clinical review and short reference on the disease status in Mediterranean countries
(2006)The article presents a brief report of our clinical experience on the Maedi-Visna infection in sheep. The clinical signs and the gross lung lesions are described. The importance of horizontal transmission by aerosol from ... -
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 ... -
Nutritional sensitivity of resistance to Trichostrongylus colubriformis in lactating ewes
(2009)It has been suggested that the periparturient breakdown of immunity to parasites has a nutritional basis. Our overall hypothesis is that it results from a prioritized scarce metabolizable protein (MP) allocation to ... -
Observations in ovine myiosis in Greece, with special reference to clinical findings and treatment of genital myiosis
(2013)The present paper reports the clinical findings in myiosis in 33 sheep and in 11 dogs in the flocks of the affected sheep. Moreover, it presents a protocol for treatment of genital myiosis. Location of lesions in affected ... -
Oestradiol concentration as a predictor of ovarian response in FSH stimulated ewe-lambs
(2007)We investigated the prediction of ovarian response using oestradiol determination, in 37 gonadotrophin stimulated Karagouniko ewe-lambs. Ovarian stimulation was induced by serial FSH administrations, and laparoscopic ... -
Physiology of pericardial fluid production and drainage
(2015)The pericardium is one of the serosal cavities of the mammals. It consists of two anatomical structures closely connected, an external sac of fibrous connective tissue, that is called fibrous pericardium and an internal ... -
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 ...
