table XIV. gains according to breeding 



The greatest gains were made in February. Each following month 

 the amount of gains gradually decreased until June, when the average 

 for the flock was 10.57 pounds increase per month. The next month 

 was especially warm and trying so that many of the lambs actually lost 

 in weight. There were a few individuals that lost in either June or 

 August, but not nearly as many as during July. Some slight differences 

 are apparent between the rate of gains of the different crosses, but 

 the average of each cross did not vary from the average of the flock. 

 It was apparent that the lambs born in May lost relatively less than 

 those born in other months, but these lambs seem to be retarded in 

 their development and did not weigh as much in the fall as the early 

 dropped lambs. 



There were 57 lambs in the flock December 1, 1916. These lambs 

 were divided into three groups according to weight. Table XV classi- 

 fies them according to breeding and weight.

Table XV shows that the Tunis lambs weighed less than any other 

 breeding, averaging 63.6 pounds. The Hampshire-Tunis-Native lambs 

 averaged 84.2 pounds, being the highest average where there were large
