The data were subjected to the General Linear Model, and analysis of variance was used to study the effect of the shape of the udder, its type, the length of the teats, the distance between them and their effect on milk production and some of its components. The results showed a significant effect of the shape and type of the udder on the total milk production and the proportion of fat and protein, while the shape and type of the udder did not affect the percentage of lactose. The overall average teat length, nipple circumference and distance between the teats were 6.16, 5.09 and 20.74 cm, respectively. It found a high significant effect of teat length in total milk production, and teat circumference in fat and protein ratio, and teat distance in total milk. The effect of teat length was significant in terms of fat and protein.
