Description: The aim of the present study was to investigate the influence of some environmental factors on the sub ratings and over-all rating of buffalo cows. Ratings of 819 buffalo cows, classified a total 2457 times by one and the same classifier were used.. - To asses the effect of the different factors was employed a linear model with the following factors: age, stage of lactation and level of milk yield of the buffalo cows.. - Lactation numbers were used as a measure of age and ratings grouped into lactations 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10. Ratings were also grouped according to stage of lactation: (1) from day of calving to 90 days; (2) 91 days to 210 days and (3) 211 days to the next calving. According to the level of milk yield ratings were grouped into 4 levels: (1) to 1500 kg; (2) 1501 kg to 1800 kg; (3) 1801 kg to 2100 kg and (4) higher then 2101 kg.. - Considerable and significant effect on the general appearance, body capacity and mammary system plays the age (lactation) of the buffalo cows; on dairy character, mammary system and over-all rating - the level of milk yield and on mammary system and over-all rating - the stage of lactation period
