Teat lesions predispose to invasion of the ovine mammary gland by Mannheimia haemolytica
(2007)
Teat lesions, produced in ewes by an experimental chapping procedure, were found to facilitate experimental infection with Mannheimia haemolytica, as assessed by observations on infection of the teat skin, teat duct and ...
Supplementation of lactating ewes with a glucogenic preparation or beta-carotene in mid- to late lactation on subsequent milk yield and luteinizing hormone secretion
(2007)
The effects of a glucogenic preparation (Nutrimix((R))) or beta-carotene (Rovimix((R)) beta carotene) supplementation of ewes during mid- to late-lactation on their milk yield were assessed in a study where 66 Chios-breed ...
Comparison of fluorescence polarization assay, indirect ELISA and competitive ELISA methods for diagnosis of Brucella melitensis-infection in small ruminants
(2004)
Three serological tests, the fluorescence-polarization assay (FPA), the indirect ELISA (iELISA) and the competitive ELISA (cELISA), were compared in detecting Brucella melitensis antibodies in 454 serum samples from sheep ...
Effects of chlortetracycline administration on the health status and performance of sows: Results of a field trial
(2003)
Objectives: To investigate the effects of in-feed chlortetracycline (CTC) during lactation on health status and reproductive performance of gilts or sows in a herd with a history of porcine reproductive and respiratory ...
Supplementation of lactating ewes with a glucogenic preparation or β-carotene in mid- To late lactation on subsequent milk yield and luteinizing hormone secretion
(2007)
The effects of a glucogenic preparation (Nutrimix®) or β-carotene (Rovimix® beta carotene) supplementation of ewes during mid- to late-lactation on their milk yield were assessed in a study where 66 Chios-breed ewes were ...
Evaluation of the efficacy of moxidectin in a herd of goats after long-standing consistent use
(2005)
Two trials were carried out in a herd of goats, where moxidectin had been consistently used for a long-standing period, in order to monitor its field efficacy. Trial I was carried out after the drug had been used for 4 ...
Subclinical mastitis changes the patterns of maternal-offspring behaviour in dairy sheep
(2008)
Subclinical mastitis was induced by inoculating one mammary gland in dairy ewes (n = 8) with a Staphylococcus simulans isolate; control ewes (n = 4) were included. The milk yield of inoculated glands decreased (P < 0.001), ...
