Assessment of genetic variation for pathogen-specific mastitis resistance in Valle del Belice dairy sheep
BACKGROUND Mastitis resistance is a complex and multifactorial trait, and its expression depends on both genetic and environmental factors, including infection pressure. The objective of this research was to determine the genetic basis of mastitis resistance to specific pathogens using a repeatability threshold probit animal model. RESULTS The most prevalent isolated pathogens were coagulase-...
متن کاملAnalyses of udder health in Valle del Belice dairy sheep using Somatic Cell Count (SCC)
Intramammary infections (IMI) are a complex of inflammatory diseases of the mammary gland. Mastitis is one of the most frequent IMI affecting small dairy ruminants. Direct selection against clinical mastitis is difficult because mastitis is not widely recorded; therefore, somatic cell count (SCC) is promoted as selection criterion for mastitis resistance. A dataset containing 2,475 first-lactat...
متن کاملRelationship between udder and leg hygiene scores and subclinical mastitis.
The objective of this study was to determine the relationship between udder and leg hygiene scores of lactating dairy cattle and measures of subclinical mastitis. Study animals (n = 1250) consisted of lactating dairy cows from eight commercial dairy farms. Herds were enrolled during December 2000 and January 2001 and were visited bimonthly for a total of five visits per herd. Udder and leg hygi...
متن کاملStudy of the relationship between oxidative stress and subclinical mastitis in dairy cattle
Subclinical mastitis is considered as one of the most prevalent diseases in dairy cows, causing drasticloss in the dairy industry. Oxidative stress, induced by reactive oxygen species (ROS), is believed to be aprimary factor in various cattle diseases including mastitis, but there are few studies regarding the role ofROS in subclinical mastitis. This study was undertaken to i) study the changes...
متن کاملIncidence and importance of subclinical mastitis in sheep.
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...
