Background: Mastitis in sheep caused by Staphylococcus spp. is a serious concern for dairy farming. Aims: The objective of this study was to evaluate the impact of the intramammary infection (IMI) caused by Staphylococcus spp. on the long-chain fatty acid profile and composition of ewe’s milk. Methods: The experiment was conducted in a herd of Zoslachtena Valaska sheep. Half-udder milk samples ...

Dairy goat and sheep farms suffer severe economic losses due to intramammary infections, with Staphylococcus aureus representing the main cause of clinical mastitis in small ruminants. In addition, S. aureus contamination of goat and sheep milk may cause staphylococcal food poisoning, as many traditional caprine and ovine milk products are not subjected to pasteurization. Data on virulence and ...

The incidence of positive CMT, indicative of subclinical mastitis, was studied in a flock of purebred Targhee ewes from four selection lines. The incidence of positive CMT was found to be random at lambing with respect to age and line of ewe, number of lambs born and weaned and sex of lambs, but at docking (3 to 7 weeks after lambing) increased with increasing age of ewe and number of lambs bor...

Contagious agalactia (C.A) is an infectious syndrome of sheep that is characterized by mastitis and subsequent failure of milk production, arthritis, abortion and keratoconjunctivitis. Mycoplasma agalactiae (M. agalactiae) is the main cause of the disease in sheep. The aim of this study was isolation and identification of M. agalactiae with culture and polymerase chain reaction (PCR) assay from...

The present study aimed to estimate the effects of parity, calving season and year of calving on the prevalence of subclinical mastitis in Holstein cows. A total of 2682 records from 869 Holstein cows in a large dairy farm (Azarbaijan province, Iran), respecting the period from 2006 to 2009, were collected. Data was analyzed using Proc Mixed of SAS software by MIVQUE method. Subclinical mastiti...

BACKGROUND The impact of food animals as a possible reservoir for extended-spectrum beta-lactamase (ESBL) producing Enterobacteriaceae, and the dissemination of such strains into the food production chain need to be assessed. In this study 334 fecal samples from pigs, cattle, chicken and sheep were investigated at slaughter. Additionally, 100 raw milk samples, representing bulk tank milk of 100...

Introduction: Health management of ewes during the dry-period is important for optimum production in sheep flocks. Health management during that period should ensure that, at lambing, ewes produce large, viable lamb(s) and have milk production adequate to ensure survival of lamb(s) until weaning. This papers presents the principles of health management of ewes during the dry-period. Some differ...
