Effect of Body Measurements on First Lactation Milk Yield in Jersey Crosses And Holstein Friesian Crosses

A study was conducted to predict the influence of body measurements on first lactation milk yield of Jersey crosses and Holstein Friesian crosses. Body weight, body height, heart girth, body length and posterior girth measurements were taken from 50 Jersey crosses and 70 HF crosses. Experimental animals were fed and managed under tail to tail system of housing at dairy farm. From the calculation of data on different parameters it is concluded that body measurements has non-significant effect on body weight, heart girth, body length, body height and posterior girth on first lactation milk yield in Jersey crosses. In Holstein Friesian crosses had significant effect on body weight and posterior girth and non significant effect on heart girth, body length and body height on first lactation milk yield in HF crosses.
