The Relationship Between Udder Measurements and Daily Milk Yield of Butana Cattle at Atbara Livestock Research Station

Abstract

Conducted measurements of the udder and teats before and after the milking of twenty-seven )27( cows of Butana dairy cattle in Atbara Livestock Research Station in northern Sudan near Atbara city, and the results showed a significant difference was high )p <0.01( between measurements of the whole )udder depth, udder circumference, udder capacity, teats circumference and teats length( before and after milking. The relationship between udder measurements and milk yield follows a day in measurements of udder depth, udder circumference and udder capacity of the positive trend and medium correlation with the amount of milk yield in the day. The teats measurements was a weak correlation with the amount of milk yield but measure the teat circumference high than teat length of the link with the milk yield other than measuring the teat length with which a relationship of a negative trend in some of the readings.
