FOODS ANIMAL PRODUCTION. 271 



The results for 80 days of this experiment were also calculated. 

 During this time the steers in the different lots made the following- 

 average gains in weight: Lot 1, 152 lbs.; lot 2. 175.G lbs.; and lot 3, 

 1!>4.<> lbs. The average cost per pound of gain for the 3 lots was 5.(52 

 cts., 3.27 cts., and 3.78 cts., respectively. 



From these experiments the authors draw the following conclusions: 



" For long and short fattening periods it seems clear that at current or probable 

 prices of meal and bulls it pays best to feed some 5 or 6 lbs. of bulls to every pound 

 of meal eaten. 



"The largest daily gain in live weight can be secured by feeding meal and bulls 

 in a very common proportion of 3 lbs. of bulls to 1 lb. of meal. The quicker gain, 

 secured by increasing the amount of meal fed daily from some 4 lbs. to 6 lbs., 

 increases the cost of feeding each steer $1.25 or $1.50 for every 100 days. 



"Changing the amount of cotton-seed meal from a light feed of meal for first 50 

 days to heavy meal feed for last 70 days gave results of no marked value, although 

 the change of ration clearly added to the cost of maintenance. 



"We were totally unable to cause 'fat sickness' in steers fed on sound, dry cot- 

 ton-seed meal and hulls when combined in various proportions and fed for 150 days, 

 continuing into hot weather. 



"When less than 2i lbs. of hulls is fed to 1 lb. of cotton-seed meal the appetite is 

 disturbed and indigestion is produced, resulting in light feeding and slow gains. 



"From the trials here reported, we may safely conclude that when the price of a ton 

 of cotton-seed meal as compared with a ton of hulls is as 5 to 1, then a pound of meal 

 fed should be accompanied by at least 5 lbs. of hulls. When the difference in price 

 widens, then the hulls should he correspondingly increased. Thus, if meal be worth 

 $15 per ton and hulls $3, at least 5 lbs. of bulls should be fed to each pound of meal; 

 if meal be worth $15 and hulls $2 per ton, 7| lbs. of bulls should be fed to every 

 pound of meal — provided the steers eat freely of the foods mixed in this proportion." 



Feeding sheep in South Dakota, E. C. Chilcott and E. A. Bur- 

 nett (Soutli Dakota 8ta. JiiiJ. 55, pp. 20). — A test was made with 45 

 lambs to compare the relative value of several common feeding stuffs. 

 When purchased the sheep weighed about 54 lbs. per head. On Sep- 

 tember 30 they were turned on to a field of rape, where they remained 

 until the middle of November. During the last 3 weeks of this time 

 they had access to a grass pasture also. In addition they were fed 

 some oats or oats and barley. 



On November 16 the lambs were divided into 5 uniform lots and after 

 a preliminary period on the rations they were to consume during the 

 experiment, the test proper began November 28 and continued 17 weeks. 

 During this time the lambs were fed 1.4 lbs. per head daily of the fol- 

 lowing grain mixtures: Lot 1 equal parts of corn, oats, shorts, and 

 linseed meal; lot 2 corn and oats, 1:1; lot 3 oats and wheat, 1:1; 

 lot 4 oats and barley, 1:1; and lot 5 wheat and barley, 1:1. In addi- 

 tion all the lots were fed 0.9 lb. of hay per head per day. The sheep 

 were kept in pens and fed twice daily, and were supplied with salt. 



At the close of the experiment the sheep were slaughtered and sold 

 for 4 cts. per pound. The financial statement is based on hay at $3, 

 shorts at $6, and linseed meal at $18.60 per ton, and oats and barley at
