1918] ANIMAL PRODUCTION'. 69 



during 1914-15 proved unprofitable, as did the finishing of prime cattle of 1,300 

 to 1,400 lbs., due to the unsatisfactory market conditions. Molasses, at $20 per 

 ton, was even less profitable than corn, at 70 cts. per bushel. 



Body measurements of steers, W. H. Tomhave and B. O. Severson {Pennsyl- 

 vania Sta. Rpt. 1915, pp. 188-208). — The measurements were taken of 72 steers 

 used in the feeding experiments noted on page 68, to gather data from which 

 correlations might be shown between form, represented by body measurements, 

 and gains in weight. The measurements and weights were obtained at the 

 beginning and the end of the feeding experiments, and the individual data for 

 each animal are shown in tables. 



The maintenance of a beef -breeding herd, W. H. Tomhave and B. O. Seveb- 

 soN {Pennsylvania Sta. Rpt. 1915, pp. 107-156, pis. 9). — A more detailed ac- 

 count of the work previously noted (E. S. R., 35, p. 168), 



The economic importance of Aberdeen-Angus cattle, W. A. Stewaet {Jour. 

 Bd. Agr. [London}, 23 {1916), No. 8, pp. 756-760).— Brief notes are given on the 

 value of Aberdeen-Angus cattle for beef and milk production and for crossing 

 with other breeds. 



[Zebu cattle], R. L. LuAces {El Gunado Cehu en eZ Mejoramiento de Nuestra 

 Ganaderia. Habana, Cuba: Sec. Agr. Com. y Trab., 1916, pp. S3, pis. 21). — A 

 discussion of breeds and cross breeds of cattle and their adaptation to the 

 tropics. Attention is called to the value of Zebu cattle, especially in tick in- 

 fested countries. The results of crossing Zebu with native and other breeds of 

 cattle are illustrated and described. 



Calf-rearing experiments at Woburn, 1916-17, J. A. Voelckee {Roy. Agr. 

 Soc. England, Occas. Notes, No. 2 {1917), pp. 9, 10).— The results of a 14 

 weeks' trial with crushed oats, calf meal, beans, palm-nut cake, and maize and 

 fish meal are reported. The highest gains were given with the maize and fish 

 meal mixture, closely followed by the palm-nut cake and oats mixture. Diffi- 

 culty was experienced in getting the calves to eat the palm-nut cake alone in 

 the beginning, though they did well on it. 



Farm sheep raising for beginners, F. R. Marshall and R. B. Millin {U. S. 

 Dept. Agr., Farmers' Bui. 840 {1917), pp. 24, figs. 6). — Information on the gen- 

 eral outlook for sheep raising in the United States and regions 'of the country 

 especially adapted to farm sheep raising is given, together with suggestions to 

 beginners on the management of the farm flock and the preparation of lambs 

 for market. 



Dry lot V. pasture crops for growing and fattening pigs for market, W. H. 

 Tomhave and H. H. Havneb {Pennsylvania Sta. Rpt. 1915, pp. 220-226). — A 

 continuation of the work previously reported (E. S. R., 35, p. 568). 



In this experiment 40 pigs were used. Lot 1 (on a dry lot of i acre well 

 drained and shaded) consisted of 21 pigs fed on a ration of corn meal and 

 tankage 8: 11. Lot 2, on a pasture lot of three 1-acre plats, A (oats and peas), 

 B (corn), and C (rape), was composed of 19 pigs fed a ration of corn meal and 

 tankage 12 :1. The pigs were transferred from plats A, B, and C as these be- 

 came exhausted. 



The average daily gain of lot 1 for 91 days was 1.029 lbs. per head, as com- 

 pared with 0.873 lb. gain made by lot 2. Lot 1, however, required 4.07 lbs. grain 

 per pound of gain to 3.31 lbs. for lot 2. Lot 2 made gains at a cost lower by 

 from 1.04 to 1.44 cts. per pound than lot 1. 



Fattening pigs for market, W. H. Tomhave and H. H. Havnek {Pennsyl- 

 vania Sta. Rpt. 1915, pp. 226-231, pis. 6). — A continuation of the work pre- 

 viously reported (E. S. R., 35, p. 568).
