Non genetic factors affecting udder type traits in Sahiwal cattle

The present study was planned to find out the magnitude of environmental factors affecting udder type traits in Sahiwal cattle. Fourteen were measured for each randomly selected 100 lactating cattle maintained at Livestock Research farm, NDRI, Karnal, India. data analysed by least squares methods using general linear model procedures including parity, stage lactation and season calving classification as fixed effects. Traits viz. Udder balance, Rear Height, Teat Diameter, Length, Central Ligament, Circumference, Width Circumference significantly (p<0.05) affected parity. Stage significant (P<0.05) source variation Shortest distance from teat ends floor, ligament while Length Width. It is, therefore, suggested that breeding value estimation conformation, these should be considered which would justify focusing genetic improvement
