1917] ANIMAL PRODUCTION. 367 



blackstrap molasses was fed to all the lots as an appetizer for 11 dajs during 

 the latter part of the experiment, the average daily allowance being 0.59 lb. 

 per head. Pigs followed all lots. 



At the close of the experiment very little difference in the gains of the four 

 lots was observed, the average daily gains being 1.62, 1.52, 1.57, and 1.55 lbs. per 

 head, respectively. Considerable advantage was found in having hogs follow 

 the calves. The dressing percentages of the different lots of calves were prac- 

 tically the same, and little difference in the quality of carcasses was observed. 



The calculations pertaining to the financial results of the experiment are 

 based on the following costs per ton of the feeding stuffs used : Cottonseed 

 meal, $35; peanut meal (hulls included), $28; cold pressed cotton.seed, $24; 

 milo maize chops, $23.80 ; corn silage, $3.50 ; sorghum silage, $3.50 ; Sudan grass 

 hay, $10 ; cottonseed hulls, $10 ; blackstrap molasses, at 16.25 cts. a gallon, $27. 

 Based on the selling prices of $9.50 per 100 lbs. for lots 1 and 3, $9.41 for lot 2, 

 and $9.43 for lot 4, peanut meal (hulls included) was worth only $21.40 per ton 

 and cold pressed cottonseed only $22.80 per ton, with cottonseed meal at $35 

 per ton, while cottonseed hulls were worth only $5.34 per ton with Sudan grass 

 hay at $10 per ton. 



Detailed data are submitted in tabular form and discussed. 



The production of baby beef, S. H. Ray {U. S. Dept. Agr., Farmers' Bui. 

 811 {1911), pp. 22. figs. 8). — This discusses the various phases of the production 

 of baby beef for market, including the breeds and type of cows, bulls, and 

 calves suitable for baby-beef production, the management and feeding of the 

 breeding herd, calf management and feeding, and hogs following baby beeves. 



Peanut meal and ground whole pressed peanuts for hogs, L. B. Burk 

 (Texas Sta. Bui. 201 (1916), pp. S-9).— The object of the experiments reported 

 was to determine the value of both peanut meal and ground whole pre.s.sed 

 peanuts when used as a supplement to milo maize chop in a ration for feeding 

 hogs; to compare peanut meal and ground whole pressed peanuts with meat 

 meal and cottonseed meal as supplements to milo maize chop ; to compare a 

 narrow peanut meal, milo maize ration with a similar balanced ration ; to 

 compare both rations with a ration of milo maize chop when fed alone ; and to 

 study the effects of peanut meal and ground whole pressed peanuts on the 

 quality of the pork and lard. 



Six lots, consisting of 10 each of pure-bred Duroc-Jersey hogs were fed the 

 following rations for 77 days : Lot 1, milo maize chop alone ; lot 2, milo maize 

 chop 6 lbs., cottonseed meal 1 lb. ; lot 3, milo maize chop 10 lbs., meat meal 

 1 lb.; lot 4, milo maize chop 7 lbs., peanut meal (without hull) 1 lb.; lot 5, 

 milo maize chop 2.5 lbs., ground whole pressed peanuts 1 lb. ; lot 6, milo maize 

 chop 1 lb., peanut meal (without hull) 1 lb. The hogs were fed twice each day 

 for two weeks, and after this they received all the feed they would clean up. 



At the close of the experiment the animals were satisfactorily firm. Detailed 

 results of the experiment and a financial statement are submitted in tabular 

 form. 



The average daily gains per head were 0.727, 1.26, 1.18, 1.21, 1.228, and 1.424 

 lbs., respectively. Lot 1, although producing a profit, was unsatisfactory when 

 compared with the other lots, lot 2 returning 85, lot 3 70, lot 5 77, lot 4 81, and 

 lot 6 105 per cent greater profits. The hogs of lot 2, although receiving an 

 average of 0.75 lb. of cottonseed meal for the entire period of the experiment, 

 showed no indications of cottonseed meal poisoning. Lot 6 produced the fastest 

 and most economical gains of any of the lots. Although half of the ration fed 

 to this lot was peanut meal, the pork was found to be firm.
