Popis:	Background: The present study was designed to find out the magnitude of environmental and other non-genetic factors affecting the linear udder and teat type traits in Sahiwal and Karan Fries cows. Methods: Total eight udder morphometric traits and seven teat morphometric traits were measured in 87 Sahiwal and 166 Karan Fries cows. The data regarding milk yield, stage of lactation, parity and season of calving for all Sahiwal and Karan Fries cows were collected. Result: In Karan Fries cows, udder and teat type traits were significantly affected by parity and stage of lactation, while in Sahiwal cow udder and teat type traits were significantly affected by parity only. Teat circumference was significantly affected by season and stage of lactation. The results indicated that parity and stages of lactation were important sources of variation for most of linear udder and teat type traits.
