EXPERIMENT WITH CHICKS, SECOND SERIES. 



The lots of chicks, XI, XIII and XV were fed the ration con- 

 taining the animal meal and Lots XII, XIV and XVI were fed 

 the contrasted ration of vegetable foods supplemented by bone 

 ash. Two-thirds of the chicks in Lots XI, XII, XIII and XIV 

 were W. Wyandotte-W. Leghorn crosses and the remainder 

 Leghorns and Wyandottes. The other two lots contained about 

 the same proportion of the cross-bred chicks, the remainder being 

 mostly Wyandottes with a few Plymouth Rocks. 



After the chicks in Lots XI and XII were ten weeks old the 

 largest cockerels were removed and the remainder fed for two 

 weeks longer on the same rations. The other four lots were fed 

 until the chicks were twelve weeks old without separating the 

 cockerels. The different lots were fed freely — all the food they 

 would readily eat. The nutritive ratios of the rations were 

 nearly alike, the ratio for the vegetable-food ration being how- 

 ever slightly wider as in the preceding experiments. The con- 

 trasted rations in this series were more nearly alike in regard to 

 the relations of the protein, ash and fats to the total dry matter. 

 The vegetable-food ration contained a slightly less proportion 

 of protein and a slightly larger proportion of ash and of fats, but 

 these differences were very small. 



The data secured in feeding the six lots of chicks are given in 

 the accompanying tables. 



relative efficiency and economy of the rations for chicks. 

 The ration containing the animal meal was eaten somewhat 

 more freely. The gains made by the contrasted lots were, how- 

 ever, very nearly equal. Lot XI ate nearly 12 per ct. more food 

 calculated on the basis of dry matter than did Lot XII, Lot XIII 

 ate nearly 16 per ct. more than Lot XIV and Lot XV over 9 

 per ct. more than Lot XVI. The gain in weight made by Lot 

 XII was less than 4 per ct. greater than that made by Lot XI, 

 the gain made by Lot XIII was nearly 10 per ct. greater than
