760 EXPEEIMENT STATION EECOBD. 



hay, oats, and bran. The cost per horse per day was 16, 18, 15, and 17 cts. for 

 the respective lots. The cost of growing a horse from weaning at five months to 

 two years of age was $33.17 and that of wintering an idle horse, $9.17. 



Four lots of 9 lambs each were fed 97 days as follows : Lot 1, clover hay and 

 alfalfa; lot 2, mixed hay and corn stover; lot 3, timothy hay and roots; and 

 lot 4, mixed hay, roots, and extra grain. They made average daily gains per 

 head of 0.085, 0.065, 0.037, and 0.106 lb., costing 22.7, 29.6. 47.7, and 16.6 cts. to 

 produce a pound of grain. Three lots of 31 lambs each fed 92 days, lot 1 receiv- 

 ing alfalfa hay ; lot 2, mixed hay and corn stover ; and lot 3, timothy hay and 

 roots, made average daily gains per head of 0.2, 0.054, and 0.068 lb., costing 

 per pound of gain 14*, 28, and 22 cts., respectively. 



In two years' lamb-feeding experiments four lots of lambs were fed 118 days 

 as follows : Lot 1, clover hay, roots, and grain ; lot 2, clover hay and grain ; lot 

 3, timothy hay, roots, and grain ; and lot 4. timothy hay and grain. They made 

 average daily gains per liead of 0.24, 0.21, 0.24, and 0.2 lb., costing per pound of 

 gain 11.4, 11.15, 11.7, and 11.82 cts. for the respective lots. Clover hay sur- 

 passed timothy hay in economy of production. When I'oots are used a better 

 daily gain is obtained, but not quite sufficient to produce any appreciable profit 

 by using them. 



In an experiment in wintering a breeding Hock, three lots of ewes were fed 

 as follows : Lot 1, alfalfa in an open shed ; lot 2, alfalfa in the sheep barn ; and 

 lot 3, hay in the sheep barn. They made average total gains per ewe during the 

 81-day period of 26.88, 27.42, and 22.06 lbs., respectively. Four lots of 25 lambs 

 each were fed 112 days as follows: Lot 1, oat straw and grain (oats and 

 barley 1:1) ; lot 2, oat straw, mixed hay, and grain; lot 3, oat straw, mixed hay, 

 grain, and turnips ; and lot 4, oat straw, alfalfa, hay, grain, and turnips. They 

 made average daily gains per head of 0.19, 0.26, 0.25, and 0.27 lb., costing per 

 pound of gain 8.3, 6.75, 7.4, and 6.9 cts,, respectively. 



In a three years' experiment six lots of about 50 lambs each were fed as fol- 

 lows : Lots 1 and 2, alfalfa, grain, and roots ; lot 3, alfalfa and roots ; lot 4, 

 alfalfa and grain ; lot 5, alfalfa and screenings ; and lot 6, alfalfa alone, lot 1 

 being composed of yearlings and the remaining five lots of lambs. They made 

 average daily gains per head of 0.23, 0.29, 0.19, 0.24, 0.23. and 0.17 lb., costing 

 per pound of gain 10.71, 7.58, 9.34, 8.32, 6.11, and 9.8 cts., respectively. 



Two lots of eight sows each were fed during the winter season, lot 1 receiv- 

 ing a mixture of wheat bran and shorts and lot 2 the same, with th eexception 

 that one-third of this mixture was replaced by tankage. The tankage-fe<l sows 

 did not consume as much grain as where no tankage was fed. The weights of 

 the sows at the beginning of the experiment and after farrowing were approxi- 

 mately the same. The average weights of litters at farrowing, at four weeks of 

 age and at eight weeks of age, were 2.44 and 2.42, 11.4 and 13.5, and 19.7 and 

 25.3 lbs. for the re.spective lots. It is concluded that, although tankage when 

 fed in these proportions is an expensive feed, yet this difference in cost is 

 counterbalanced by greater ruggedness of litter.s, lower percentage of mortality, 

 and the increased weight of litters at eight weeks of age. 



Two lots of seven pigs each were fed four months as follows: Lot 1 ground 

 oats, feed flour, and mangels, and lot 2 ground barley, feed flour, and mangels. 

 They made average daily gains of 0.6 and 0.67 lb, per pig, costing per pound of 

 gain 4.60 and 4.03 cts., respectively. Two lots of four pigs each fetl three 

 months, lot 1 twice a day and lot 2 three times a day, made average daily 

 gains per head of 1.13 and 1,1 lbs,, costing 3.35 and 3.45 cts. per pound of gain, 

 respectively.
