(i) This average is depressed by the abnormally low gain recorded in the last week when 2 gilts, 

 being in oestro, not onlj' failed to gain in weight, but caused general disturbance of the whole lot. The 

 average for the preceding 2 weeks were: Lot A, 14.4 lbs.; Lot B, 14.7 lbs. 



Lot B. Seven weeks later again fish meal was once more substituted for an 

 equal weight of sl^arps in the ration of Lot A, but was not removed from 

 the ration of Lot B, so that for the last 4 weeks each lot received fish meal 

 along with the bran and sharps and for the last 3 weeks the rations were 

 identical in every respct. The general plan of the ex]:)eriment is sunmiari- 

 sed in Table I. 



The composition of the fish meal used is given in Table XL average 

 gains in live weight are summarised in Table III, and in Table IV are set 

 out the quantity of foodstuffs consumed and the average cost of the rations 

 based on the following prices per ton:
