FISH MEAL IN ANIMAL FEEDING 377 



age " in lot 2. The average daily gains during the 101-day feeding 

 period were 1.58 and 1.34 pounds per head, respectively. The feed 

 consumed per 100 pounds of gain was 352 pounds of corn and 20.9 

 pounds of '' digester tankage " in lot 1, and 389 pounds of corn and 

 25.2 pounds in lot 2 of '* marine tankage." 



The following is quoted from the 1928 report of the New Jersey 

 Agricultural Experiment Station : " For each 100 pounds of gain 

 pigs fed corn supplemented with fish meal required 359 pounds of 

 feed, while those receiving tankage instead of fish meal required 

 402 pounds of feed. Pigs in the first lot gained at the rate of 1.48 

 pounds and those in the second lot 1.33 pounds per head daily." 



According to Hostetler and Halverson (1928) pigs averaging 42 

 j)ounds per head were divided into 3 lots of 15 head each and fed a 

 mixture of corn meal, wheat shorts, fish meal, and minerals. Tlie 

 protein content of the ration was decreased as the pigs increased in 

 live weight. Lot 1 was fed in dry lot and lots 2 and 3 on orchard 

 grass pasture, but in the latter lot only half as much shorts and fish 

 meal was fed as in the other lots. Death losses of 5 pigs in lot 1, 

 3 in lot 2, and 4 in lot 3 made the results somewhat unsatisfactory. 

 The average daily gains in the respective lots were 1.23, 1.25, and 

 1.2 pounds per head, and for each 100 pounds of gain the respective 

 lots required 362, 363, and 375 pounds of feed. 



Nance (1928) reported that the rate of gain, feed consumption, and 

 cost of gain were practically the same in tsvo lots of pigs, one of 

 which received shelled corn, fish meal, and minerals and the other fish 

 meal and cottonseed meal, equal parts, instead of fish meal alone. In 

 the latter lot, 26 pigs were fed the cottonseed-meal supplement for 

 153 days without any apparent harm. 



Nance (1928a) fed shelled corn and minerals to two lots of 8 pigs 

 each, averaging approximately 100 pounds per head. In addition 

 to this basal ration, lot 1 received fish meal and lot 2 whale meal 

 as protein supplements. The average daily gains were 2.04 and 1.28 

 pounds per head in the respective lots. Lot 1 required approxi- 

 mately 100 pounds less feed to produce 100 pounds of gain than did 

 lot 2. Both lots consumed about the same amount of protein supple- 

 ment, but lot 2 ate 3.7 times as much mineral and 153 pounds less 

 ■of corn than lot 1. 



The American Fertilizer (1929) in commenting on swine-feeding 

 tests at the Georgia Agricultural Experiment Station, stated that 

 Edwards obtained 123.3 pounds of gain in 57 days on fish meal and 

 only 99.1 pounds of gain on digester tankage. The comparative 

 figures on cost were $7.49 to $8.48, favoring the fish meal. 



Manning (1930) reported that the addition of 10 per cent of fish 

 meal to the ration produced excellent results in sAvine feeding. 



The following three paragraphs are abstracted from the North 

 Carolina Agricultural Experiment Station report, dated June 30, 

 1928 : 



North Carolina (1928) stated that 4 groups of 15 pigs each were 

 self-fed corn, fish meal, and minerals. In group 3 ground soybean 

 hay and in group 4 ground alfalfa hay replaced one-fourth of the 

 fish meal. The mineral mixture was composed of 10 pounds of
