772 EXPERIMENT STATION RECORD. [Vol.38 



4 lbs. palm-kernel cake, in lot 3 with 4 lbs. palm-kernel meal, and in lot 4 with 

 4 lbs. coconut cake. During the third and fourth months 1 lb. of these four 

 cakes in the four rations was replaced with 0.25 lb. soy cake and 0.5 lb. maize 

 meal to make the rations more palatable. The bullocks during the four months 

 made average gains each per week as follows: Lot 1, 16.5; lot 2, 12.44; lot 3, 

 14.19 ; and lot 4, 15.7 lbs. The average profits per head for the four months 

 were for lot 1, £4 5s. 4d. ($20.77) ; lot 2, £3 2s. 4d. ; lot 3, £5 19s. 7d. ; aud lot 4, 

 £3 10s. 3d., respectively. The heifers gained 8.92, 10, 9.25, and 7.42 lbs. each 

 per week, respectively. The profits were for the entire period per head as fol- 

 lows : Lot 1, £2 14s. ; lot 2, £3 4s. Id. ; lot 3, £2 19s. 5d. ; and lot 4, £2 9s. 7d., 

 respectively. 



In the experiment with store (stocker) cattle just over six months old three 

 lots of 11, 5, and 6 head, respectively, were used. Lot 1 was fed a daily ration 

 per 500 lbs. live weight of 10.5 lbs. seeds hay, 0.5 lb. soy cake, and 2.5 lbs. 

 palm-kernel cake ; lot 2, 10.2 lbs. seeds hay, 0.5 lb. soy cake, and 2.5 lbs. palm- 

 kernel meal; lot 3, 25 lbs. swedes, 6 lbs. seeds hay, 1 lb. soy cake, and 2 lbs. 

 palm-kernel cake. The average weekly gains per head were for lot 1, 7.44 lbs. ; 

 lot 2, 9.5 lbs. ; and lot 3, 11.06 lbs. The profits per head for the 16 weeks of 

 the experiment were for lot 1, 10s. ; lot 2, £1 3s. 3d. ; and lot 3, 10s. Id. Lots 1 

 and 2 were wintered outside and lot 3 inside. Lot 3 made better average gains, 

 but the lots wintered outside were in better feeding condition and valued 

 higher in the spring. 



The sheep were divided into three lots of 16 each and fed the following 

 rations daily per 100 lbs. live weight: Lot 2, 8 lbs. swedes, 1.5 lbs. seeds hay, 

 0.4 lb. soy cake, 0.4 lb. Egyptian cotton cake, and 0.25 lb. maize meal ; lot 2, 

 7.2 lbs. swedes, 1.2 lbs. seeds hay, 0.4 lb. soy cake, and 0.5 lb. palm-kernel cake ; 

 aud lot 3, 8 lbs. swedes, 1.2 lbs. seeds hay, 0.4 lb. soy cake, and 0.5 lb. palm- 

 kernel meaL Those with cotton cake in the ration gained an average of 1.82 

 lbs. per week, with palm-kernel cake 1.8, and with palm-kernel meal 1.89. The 

 gains above expenses for the three months of the trial were for the three 

 lots 3s. ; 4s. 6d. ; and 5s. per head, respectively. 



Palm-kernel meal containing less than 2 per cent of oil gave better results 

 with all the animals than palm-nut cake containing nearly 6 per cent The 

 meal and cakes were stored in a granary and kept in good condition for some 

 mouths. No diflSculty was encountered in getting the animals to eat them. 

 The composition of the cakes and meal used in the experiments is shown.
