768 EXPERIMENT STATION RECORD. [Vol. 40 



sumed were In excess of those called for by the modified Wolff -Lehmann stand- 

 ard. Body weight, height at withers, depth of chest, and width at hips were 

 determined every 30 days and these data, together with the amount of feed 

 consumed in successive 10-day intervals, are published in tables. The average 

 of weights and measurements of 66 normally fed heifers are presented for 

 comparison. 



At the end of 6 months the Jersey calf had increased his body weight 111 

 per cent. At the end of 5 months the Holstein had increased his 91 per cent, 

 while the heifers in 6 months averaged a 315 per cent increase. During the 

 same periods the percentage in< in height was 14 for the Jersey, 27 for 



the Holstein, and 35 for the heifer calves. Increase in depth was 19, 11. and 57 

 per cent, respectively, and in width 17. 21. and 75. Neither of the experimental 

 animals throve after reaching the age of 3 months. They suffered from fits and 

 large patches of skin became devoid of hair. 



Autopsies were made of both calves. The bones of the Jersey steer "were 

 very flexible as if Insufficient ash were present; the leg bones could be bent 

 comparatively easily, while the rtbs had a very thin coating of hard material 

 with a soft core. None of the bones was as rigid as would He expected in an 

 animal of similar age. There was one atrophied kidney (perhaps congenital) 

 with hypertrophy of the other. The mesenteric lymph glands were much 

 enlarged and there was an ap] arenl leukemia. The rumen was of normal size, 

 but the walls were evidently atonic, due apparently to a development of 

 lymphoid tissue. The omasum was smaller than would he expected, though the 

 two remaining compartments of the stomach appeared to be normal. The con- 

 tents of the rumen resembled thin cottage mixed with hair." In the case 

 of the ('.months Holstein bull, the hones "appeared to be in fairly good con- 

 dition, though one or two of the ribs might previously have been broken and 

 healed. The mesenteric lypmh glands were enlarged and both kidneys were in 

 bad condition with cysts. Ail the stomach compartments were of about normal 

 size, but there were streaks of dark brown or black pigment on the inner wall 

 of the abomasum. The contents of the rumen were similar to those" of the 

 Jersey calf. 



Effect of rust on [the feeding value ofl wheat straw. F. T. SHUTT (Canada 

 /;.//»/. Farms Rpts. 1917, p. 25).— Analyses in the laboratory of the Dominion 

 chemist show, it is stated, that si raw from rusted wheat has a higher protein 

 and a lower crude liber content than straw from rust-free wheat. This sti. 

 tion as to the superior feeding qualify of the former is confirmed by the obser- 

 vations of several farmers that it is eaten by cattle with avidity. If not too 

 seriously affected with rust, it is counsumed in preference to fully mature 

 rust-free straw. The analytical data are not published. 



[Chemical analyses of] brans and shorts. P. T. Sin i r (Canada Wxpt. Farms 

 Rpis. 1917, p. 85).— Brief note is made of the protein, fat. and fiber content of 

 Canadian samples of bran and shorts. 



Cull beans for fattening steers. G. A. BboWn {Michigan Sta. (Jiiart. BuL, 

 1 (1918), No. 2, p. 41).— Culls resulting from damage to the Michigan bean crop 

 were tested out as feed for steers. There were three lots Of six steers each. 

 The roughage consisted of corn silage and clover hay. 



The lot receiving a grain ration of corn meal and cull bean meal in the ratio of 

 about 3:1 did not relish the bean meal and made only 1.91 lbs. daily gain per 

 steer. Another lot given corn meal and cooked bean meal in a ratio (<( about 

 2:1 found the mixture appetizing and made an average daily gain of 2.12 lbs. 

 The check lot fed corn meal and cottonseed meal gained '_'."."> lbs. daily. 



Cattle [feeding experiment in Nova Scotial. W. S. l'.i.un (Canada F.rpt. 

 Farms Rpts. 1917, p. 72).— A lot of 12 steers fed swede turnips and hay during
