5G Report of the Department of Animal Husbandry of the 



RELATIVE EFFICIENCY AND ECONOMY OF THE RATIONS. 



In the food eaten by Lot III there was about 37 per cent more 

 dry matter than in that eaten by Lot IV and the gain in weight 

 was about 54 per cent greater. One poimd gain was made by Lot 



III for every 4.G lbs. water-free food and one pound gain by Lot 



IV for every 5.2 lbs. of water-free food. The food cost of growth 

 was nearly 27 per. cent greater for Lot IV, the cost of food per 

 pound gain in weight during the fourteen weeks being 5.6 cents 

 for Lot III and 7.1 cents for Lot IV. 



During the preliminary period of three weeks with part of the 

 chicks, those having the animal meal ration gained 13.5 per cent 

 more in weight and consumed 17 per cent more food. The water- 

 free food required was 3.6 lbs. by Lot III for each pound gain in 

 weight and 3.4 lbs. by Lot IV. The food cost per pound gain 

 was about 4.1 cents for Lot III and about 4.7 cents for Lot IV. 



The average weight of 1 lb. was reached by Lot III three and 

 one-half weeks sooner than by Lot IV and the average weight of 

 2 lbs. over four weeks sooner. When the chicks in Lot III had 

 attained the average weight of 3 lbs. those in Lot IV averaged less 

 than 2.2 lbs. 



THE FEEDING TRIAL WITH COCKERELS. 



The feeding trial with the two lots of cockerels began in Sep- 

 tember when they were about three months old. The two lots 

 were alike at the start and averaged almost exactly the same in 

 weight. As in the other feeding trials the amount of protein sup- 

 plied per fowl was about the same for the two lots, but the nutri- 

 tive ratio was somewhat wider with the animal meal ration.
