Citrus fruit rinds as a hog feed, R. S. Allen (Maryland Sta. Bui. 227 

 (1919), pp. 193-202). — When it is recommended on sanitary grounds that gar- 

 bage destined for hog feeding be cooked, tlie author has encountered a belief 

 that cooked citrus fruit I'inds are poisonous to hogs. To test this, an experi- 

 ment with 4 lots of 3 hogs was instituted at the request of the National Re- 

 search Council. All lots received corn meal, linseed meal, and tankage 

 (94:3:3). One lot was given no additional feed, and the others i-eceived lib- 

 eral allowances of cooked orange rind, cooked lemon rind, and cooked grape- 

 fruit rind, respectively. The rinds constituted about a third of the feed con- 

 sumed. The grapefruit lot was discontinued after 40 days owing to shortage 

 of material. The others wei'e fed 89 days. The weights of the individual 

 pigs every 10 days are tabulated. No toxic influence was detected. The orange 

 and lemon fed lots consumed, respectively, 6.7 and 5.7 lbs. of feed per pound 

 of gain, while the check lot required 10.5 lbs. 



[Feed records of Canadian horses] (Canada Expt. Farms Rpt. 1918, pp. 8^, 

 85, 90, 91). — The amounts of feed consumed by 2 foals and their dams at the 

 experiment station, Ste. Anne de la Pocatiere. Que., are reported by J. Begin 

 (pp. 84, 85). A Percheron mare with a 45-day colt was purchased. During 5 

 months of nursing the mare consumed 1,888 lbs. of grain and chop and 1,975 

 lbs. of hay, and was on pasture 2.5 months. The feed consumed by the colt 

 during the first 7 months after weaning consisted of 579 lbs. oats, 624 lbs. 

 bran, 809 lbs. chop, 2,234 lbs. hay, 75 lbs. whole milk, and 678 lbs. roots. The 

 mare weighed 1,750 lbs. and the colt at 3 months. 590 lbs., and at 12 months, 

 1,175 lbs. 



The dam of a Percheron filly born April 11, 1917, consumed during the nurs- 

 ing period (up to November 1) 901 lbs. oats, 683 lbs. bran, 100 lbs. chop, 

 and 2,384 lbs. hay, and was on pasture 4.5 months. During the 5 months 

 after weaning the filly ate 478 lbs. oats, 448 lbs. bran, 152 lbs. chop, 71 lbs. 

 whole milk, and 497 lbs. roots. The mare weighed 1,775 lbs. and the colt at 

 3 months 540 lbs., and at 12 months, 1,125 lbs. 



Feeding records of horses at the Cap Rouge, Que., Experimental Station are 

 reported by G. A. Langelier (pp. 90, 91). All feed given to a colt and two 

 fillies was weighed until they were broken and put to work at an average age 

 of 34 months, 7 days. The quantities consumed per head were 13,063 lbs. hay, 

 4,278 lbs. oats, 4,830 lbs. bran, 29 lbs. wheat, 5 lbs. linseed meal, 1,036 lbs. skim 

 milk, 29 lbs. whole milk, and a "very little pasture." Similar records of 2 

 working mares for a year are also averaged, the quantities being 4,440 lbs. 

 hay, 4,770 lbs. oats, 972 lbs. bran, and 132 lbs. common molasses per head. 

 The average number of hours of work was 1,639. 



Feeding' experiments with Leghorns, A. G. Philips (Indiana Sta. Bui. 227 

 (1919), pp. 3-28, figs. 7).— Feeding experiments with White Leghorn pullets 

 during the years 1914-15 to 1917-18, in continuation of those previously noted 

 (E. S. R., 34, p. 376), and studies of the influence of confinement on egg produc- 

 tion made in 1913-14 with hens and in 1914^15 with pullets are reported. The 

 grain and mash rations and general treatment were the same as in the contem- 

 poraneous Plymouth Rock experiments (E. S. R., 40, p. 76). Three pens of 30 

 birds each were used in each of the six experiments. 



The fir.st two feeding experiments were duplicates. One pen received 5.3 

 lbs. of cottonseed meal mixed with the mash, another liad 50 lbs. of buttermilk 

 to drink for each 35 lbs. of standard grain and mash, while the third received 

 50 lbs. of buttermilk and a double allowance of grain, making the ratio of 

 grain to mash 5 : 1. 



The other two feeding experiments also duplicated each other. One pen was 

 fed onlv the standard grain and mash, while the second and third received
