ANIMAL PRODUCTION. 



Range forages, 11. 11. Fukbes aiul W. W. Skinnek {Arizoud Sta. lipt. 1903, pp. 

 o46'-350). — Analyses are reported of greasewood {Sarcobatus vermicularis) , paloverde 

 twigp, ^vater grass {Chloris ekf/ovs), 2 varieties of grama grass (one fresh the other 

 old ami weathered) , and several varieties of saltbush. The composition of a number 

 of these is shown in the following table:

"Greasewood and paloverde twigs are instances of the 'browse' forage upon which 

 animals so largely depend in semiarid country when grass is short. These are of 

 surprisingly nutritious character, as indicated by the analyses here given, being rich 

 in protein, fat, and carbohydrates. The sample of greasewood is especially good, 

 being consideraldy richer in protein and fat than a sami:)le of alfalfa hay from the 

 station farm. 



"The low protein in old, weathered 'grama' grass, as compared with fresh grasses 

 of the same general nature, bears out the low estimate generally placed ui:)on 

 weathered grass as forage." 



Commercial feeding stuffs in the Connecticut market ( Connedicul State Sta. 

 Bui. 145, pp. 5'J) . — In accordance with the j)rovisions of the State feeding stuff law 

 analyses are reported of cotton-seed meal, linseed meal, wheat bran, middlings and 

 nnxed feed, maize meal and bran, gluten meals and feed, hominy meal, rye feed, 

 l)rewery and distillery products, oat feeds, buckwheat middlings, miscellaneous 

 mixed feeds, poultry feeds, proprietary, dairy, stock, and condimental feeds. The 

 different classes of the feeding stuffs analyzed are discussed. 



Regarding the proprietary, dairy, and stock feeds, the author notes that these feed- 

 ing stuffs were made up of such materials as oat, wheat, and corn products, cotton- 

 seed meal, linseed meal with fenugreek, carob beans, and common beans in addition 

 in the case of one of the materials examined. The most concentrated, of these mix- 

 tures contained 24.6 per cent protein and the others ranged from 7.81 to 20.06 per 

 cent. The prices varied from $21 to $70 per ton. 



"A mixture of 1,000 lbs. of gluten feed and 1,000 ll^s. of mixeil wheat feed made 

 at home would cost at present retail prices $24.76. It would contain a good deal 

 more protein than could be bought for the same money in any of these factory- 

 niixe<l feeds and would have a higher feeding value. It would also have this added 

 advantage, that the feeder would know exactly what his animals were eating. 



"In other words, the cost of most of these factory-mixed feeds is (luite out of pro- 

 portion to their feeding value." 



Commercial feeding stuffs, J. L. Hills, C. II. Jones, and F. M. Hollister ( Ver- 

 mont Stn. Bui. 104, jip. 187-lDJ) . — In order to learn how the actual compared with 

 the guaranteed composition, a number of analyses were made in accordance with the 

 State feeding stuff law of cotton-seed meal, linseed meals, gluten meals and feed, 

 dried distiller's grains, oat and other commercial feeds, provenders, wheat offals, and 

 condimental feeds. In most cases protein was the only constituent determined. The
