The bufialo Rukminia yielded 10-5 lb. of milk per day at the first 

 period and 7-5 lb. at the second period during the course of which she 

 dried off. 



The yields of milk by Lachminia were 13-5, 15-3 and 14-9 lb. respec- 

 tively during the three periods of the experiment. The general tendency 

 towards a rise in the curve of the milk yield of Lachminia is apparently 

 due to the progress in lactation. The tendency towards a fall in Phulia's 

 curve seems to be due to the same cause. Milk yield generally rises for 

 the first two months after calving, after which it falls more or less 

 regularly until the end of the lactation period^.

Chart III. Percentage of fat in milk. 



The herd of cows (on mustard cake) produced 11-2 lb. milk per day 

 per animal. 



Judging the records as a whole the feeding of poppy cake does not 

 seem to injuriously affect the milk yield. 



Percentage of fat in the milk. This is shown in Chart III. The average 

 fat contents in the milks of cow Phulia and buffalo Lachminia were 3-6, 

 4-3, 4-6 and 5-5, 6-1, 6-4 per cent, dming the three periods respectively. 

 Rukminia's milk contained 6-8 per cent, during the first and 7-5 per
