a total of 573 lbs. of pork, and a net return of $47.48 per acre. Feeding the 

 alfalfa in this manner saved the expense of harvesting the hay and retained 

 the manure produced by the pigs. 



Rape pasture for pigs in cornfield. — Kaoliang for pigs, J. W. Wilson 

 (South Dakota Sta. Bui. 157 (1914), pp. 131-143, figs. 5).— The. object of the 

 first experiment was to determine the relative feeding value of several varieties 

 of corn for hogging off purposes. Six lots of six 90- to 100-lb. pigs each were 

 fed for six weeks as follows : Lot 1 Minnesota No. 13 corn, lot 2 Minnesota 

 No. 13 corn and rape, lot 3 Wisconsin White Dent corn, lot 4 Wisconsin 

 White Dent and rape, lot 5 Yellow Triumph flint corn, lot 6 Yellow Triumph 

 flint corn and rape. The average daily gains per head were 1.04, 1.11, 1.08, 

 1.36, 1.05, and 1.38 lbs. for the respective lots. 



The results indicated that flint corn is about equal to dent corn for pigs. 

 There was a marked difference in the growth of rape in the different kinds 

 of corn. The best growth was in the lot planted to Wisconsin White Dent 

 corn, the next best in Yellow Triumph flint, and the poorest in Minnesota No. 

 13. The 18 pigs in the three lots receiving coi*n without rape made an average 

 daily gain per head of 1.06 lbs., as compared with 1.28 lbs. for the 18 pigs receiv- 

 ing rape pasture in addition. The results obtained from the lot planted to rape 

 and Minnesota No. 13 corn were poor, owing to the rank growth of the com 

 and the consequent stunted growth of the rape. It is concluded that the low- 

 growing varieties of dent com are to be preferred to the tall-growing varieties 

 to secure a suitable growth of rape. 



Four lots of four 150- to 250-lb. hogs each were fed for 55 days as follows: 

 Lot 1 kaoliang meal and alfalfa hay, lot 2 kaoliang meal, lot 3 com meal and 

 alfalfa hay, and lot 4 com meal. The average daily gains per head were 0.98, 

 0.87, 1.32, and 1.19 lbs., the consumption 5.81, 6.61, 4.63, and 5.22 lbs. per pound of 

 gain, and the cost 6.56, 6.61, 5.19, and 5.22 cts. per pound of gain for the 

 respective lots. Kaoliang grain is not deemed as good as corn for fattening 

 pigs, but considering its drought-resisting qualities it is a better feed to grow 

 in some sections than corn. 



A metabolism crate for swine, E. B. Fokbes {Ohio Sta. Circ. 152 (1915), pp. 

 75-85, figs. 11). — This circular gives plans and descriptions of a metabolism 

 crate devised by the author and used in experimental work at the Ohio Station. 



Rations for growing and fattening roasters and capons, W. J. Buss (Ohio 

 Sta. Bui. 284 {1915), pp. 153-172, figs. 2).— Five lots of 39 10-week-old chicks, 

 94 cockerels and 101 pullets, were selected June 18. All but 8 of the cockerels 

 were caponized July 31. The pullets were removed soon after they began to 

 lay, and the 8 cockerels December 3. The remaining birds were fed until 

 January 27. The rations for the 32 weeks were as follows : Lot 1, com and a 

 mash of ground corn and beef scrap 2:1; lot 2, corn and a mash of ground 

 corn and beef scrap 2 : 1 during the first week, the amount of corn being in- 

 creased one part each week so that the mash for the thirty-second week was 

 ground corn and beef scrap 32 : 2 ; lot 3, corn, wheat, and oats 11 : 15 : 4, and a 

 mash of ground corn, bran, and beef scrap 2:2:1; lot 4, corn and a mash of 

 ground corn and tankage 7:3; lot 5, corn and a mash of ground corn and oil 

 meal 3 : 4, fed for 12 weeks, and replaced by a mash of ground corn and beef 

 scrap 2 : 1 thereafter. 



The birds made an average weekly gain of 0.202, 0.2, 0.206, 0.185, and 0.181 

 lb. per bird, consuming per pound of gain 7.32, 7.71, 8.45, 7.67, and 7.52 lbs. of 

 feed per bird, and costing 9.09, 8.67, 11.66, 9.1, and 9.25 cts. per pound of gain 

 for the respective lots. The capons made more rapid gains than did the pul- 

 lets. For the entire time that they were in the experiment only 32 i)er cent 

 of the capons gained less than 0.2 lb. per week, while 81 per cent of the pullets
