■tiead per day. The gain made was 25.6 lbs. per horse in 140 days. A ration 

 consisting of oats, corn, wheat bran, and timothy hay in the ratio of 4 : 6 : 4 : 12 

 produced 6 lbs, of gain in 120 days, and the animals showed the best condi- 

 tion of any in the test, but the ration cost 19 cts. per day. When oil meal 

 was used to replace a portion of more expensive grain at the rate of about 1 

 lb. per day the horses showed excellent condition and there was no evidence 

 of softness. This cheapened the ration about 2 cts. per day over the ration 

 previously used. 



[Report of] the professor of poultry husbandry, W. R. Graham {Ann. Rpt. 

 Ontario Agr. Col. and Expt. Farm, 37 {1911), pp. 159-167). — During the year 

 23 bred-to-lay Barred Plymouth Rock pullets laid 3,514 eggs, as compared 

 with 2,482 laid by exhibition pullets. The latter ate more feed but were 

 larger birds. Data on economic egg production of 341 fowls for 11 months 

 are summarized in the following table : 



Egg record of hens and pullets from October 1, 1910, to September 1, 1911. 



The following table summarizes the effects of different animal feeds in a 

 mixed ration upon egg production. Each lot consisted of 25 females and 2 males. 



Feeding tests loith Buff Orpingtons frwn October 1, 1909, to April 30, 1910, 

 and with Rhode Island Reds from October 1, 1910, to Maij 81, 1911. 



The average cost of feed for 100 hens kept in an open house was 16.5 cts. per 

 dozen. In a feeding test which involved 583 chickens, kept in colony houses 

 on a ration of mixed grain and buttermilk, 3.3 lbs. of grain was required to 

 produce 1 lb. of growth.
