464 EXPERIMENT STATION RECORD, 



9.G4, 8.95, uud 8/J cts., aud giving a net profit i>er lamb of $1.43, $1.37, $1.43, 

 and $1.00, respectively. It Is concluded from this experiment that clover hay 

 surpasses timorhy hay in the economy of gains produced. Roots appeared to 

 add to the economy of production, especially when applied to the timothy 

 hay ration. 



Six lots of approximately 75-lb. wethers were fed for 117 days as follows: 

 Lot 1 (laml)s), alfalfa, mixed grains, and roots; lot 2 (yearlings), alfalfa, 

 mixed grains, and roots; lot 3 (yearlings), alfalfa and grain; lot 4 (yearlings), 

 alfalfa and screenings; lot 5 (yearlings), alfalfa alone; lot 6 (yearlings), 

 alfalfa and roots, made an average daily gain per head of 0.289, 0.24, 0.226, 0.242, 

 0.138, and 0.14G lb., costing per pound of gain 7.19, 9.03, 9.16, 5.85, 12.32, and 12.13 

 cts., and giving a net profit per lamb of 64, 46, 46, 138, 25, and 16 cts. 



Two lots of 7 65 to 70-lb. pigs, fed 84 days a grain mixture of shorts and a 

 proprietary feed and 5 lbs. of skim milk, lot 1 receiving in addition all the 

 clover they would eat, made an average daily gain per pig of 1.U9 and 1.19 lbs- 

 costing per pound of gain 4.1 and 5.2 cts. LYom these results it is concluded 

 that greater daily gains may be made from the grain and milk ration but 

 more economical gains may be made by the addition to the ration of grain aud 

 good clover. The pigs receiving the clover were not as well finished but had 

 greater bone and muscular development, appeared to be in better condition, and 

 were at no time off feed. 



Five groups of 10 pigs each, each group comprising 2 lots, were fed for 63 

 days winter rations as follows: Group 1, ground barley and oats 1:1; group 



2, ground barley aud oats 1 : 1 and 3 lbs. per pig per day of skim milk ; group 



3, gix)uud barley and oats 1: 1 aud boiled turnips; group 4, ground barley, oats, 

 and middlings 1:1:1; and group 5, ground oats, barley, and feed flour 1:1:1. 

 They made an avei'age daily gain per head of 0.99, 1.3, 1.03, 0.92, and 0.94 lbs., 

 costing per pound of gain 5.6, 4.1, 5.55, 4.85, and 5.05 cts. From this experiment 

 it is concluded that skim milk is an outstandingly cheap pork producer; that 

 middlings is the next cheapest substitute for a part of the oats aud barley 

 meal ; that for younger and light pigs feed flour is not a practical feed in large 

 quantities ; and that cooked turnips added to the meal ration economizes but 

 little over the meal alone. 



Two lots of 5 30-lb. pigs fed 132 days a grain ration, lot 1 receiving in addi- 

 tion 3 lbs. of skim milk per pig per day, and lot 2, 6 lbs. of skim milk, made 

 average daily gains of 0.81 and 1.03 lbs., costing per pound of gain 5.08 and 5.2 

 cts., resi>ectively. The extra milk fed to lot 2 was estimated to be worth for 

 fattening puriwses 57 cts. per 100 lbs. 



Two lots of 70 to 75-lb. pigs fed 60 days a small quantity of feed flour and 

 some mangels, lot 1 receiving in addition barley chop, aud lot 2 shorts, mad* 

 a\erage daily gains per head of 0.81 and 0.58 lb., costing 4.26 and 7.4 cts. per 

 pound of gain, respectively. 



Three lots of Yorkshire pigs were fed summer rations as follows : Lot 1, 

 wheat shorts, milk, and green feed ; lot 2, wheat shorts, peas, oats, barley, rice 

 meal, aud green feed; aud lot 3. oats, peas, barley (ground), milk, and green 

 feed. They made an average daily gain per head of 1.16. 1.1. aud 1.42 lbs., 

 there being required i)er pound of gain 2.1, 2.76. aud 2.11 lbs. of grain and 

 8.51, 9, and 7.03 lbs. of milk, resi)ectively. 



Four lots of four Yorkshire pigs three to six months old were fed winter 

 rations as follows: Lot 1, rice meal, milk, and mangels; lot 2, wheat shorts, 

 milk, and mangels ; lot 3, rice meal, wheat shorts, milk, and mangels ; and lot 



4, oats, peas, barley, wheat shorts, milk, and mangels. They madj average daily 

 gains per head of 0.70S, 1.176, 0.925, aud 1.04 lbs., respectively.
