Analyses 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 کاملComparative Effect of Different Milking Methods and Udder Hygiene on Somatic Cell Count and Milk Quality in Dairy Cows
108 milk samples were collected to study the relationship of somatic cell counts (SCC) and milk composition with milking methods and udder hygiene from 27 Holstein Frisian (HF) dairy cows having moderate milk yield in mid-lactation and parity of 2 to 4, at Khyber Pakhtunkhwa Agricultural University Peshawar dairy farm. All animals were randomly distributed into three categories on the basis of ...
متن کاملEffects of udder traits on the milk yield of sheep
In order to determine the possible effects of udder traits on milk yield and milk composition a serial of experiments were carried out on five different sheep farms, between 1998-2000. Ten breeds and genotypes were included in these experiments: Merino, (Merino x Pleven Blackhead) F1, Pleven F1 x Black East Friesian, Lacaune, (Merino x Lacaune) F1, British Milksheep, (Merino x British Milksheep...
متن کاملGenetic analysis of somatic cell score and udder type traits in South African Holstein cows
_______________________________________________________________________________________ Abstract Selection accuracy for resistance to mastitis may be increased by combining somatic cell score (SCS) and udder type into an udder health index, using genetic parameter estimates among them. A multi-trait animal model was used to estimate genetic parameters among lactation average SCS and udder type ...
متن کاملChanges of physico-chemical characteristics, somatic cell count and curd quality during lactation and their relationships in Lacaune ewes
The aim of research was to evaluate changes of physico-chemical characteristics, somatic cell count and curd quality during lactation and their relationship in Lacaune ewes. The study was carried out on eighteen ewes of the second lactation on an organic farm in Valašská Bystřice (Czech Republic). It was found that the stage of lactation significantly affected almost all monitored traits except...
