240 EXPERIMENT STATION RECORD. 



The average giiin i^cr week of all tlie lambs before shearing was 1.9 

 lbs. per lamb and after shearing 2.8 lbs. Diagrams are given showing 

 the relation of the gain in weight to the temperatnre and to the protein 

 and the carbohydrates of the ration, respectively. 



The author's summary of the results of the experiment is as follows: 



"(1) Lots receiving corn hi the grain ration, either in whole or in part, produced 

 tht best gains, were aiTt)arentl.y in better finish, and in general were fed at a greater 

 profit than the lots receiving bran or oats. 



"(2) A grain ration of bran proved to be ani nferior material for fattening lambs. 



"(3) A ration of corn and oats jiroduced slightly better resnltsthan either a mixture 

 of corn and bran, or of corn, oats, and bran. 



"(4) The results of this experiment indicate that the gains resulting from fatten- 

 ing lambs by means of a 'self feed' [lot 10] are produced by a lai-ger consumption 

 cf grain for 1 lb. of gain than when fed at regular intervals in the usual manner, 

 and other things being equal the gains are less profitable. 



"(5) A mixture of fodder articles comjiosed largely of a good quality of silage ^iroved 

 a cheap and successful ration for fattening lambs. 



"(6) The rate of gain was apparently increased by shearing during the fiitteniug 

 period. 



"(7) In this experiment colder temperatures were quite generally accompanied by 

 increased gains. 



"(8) The amount of available protein in the various rations was apparently a less 

 potent factor in producing gains than the amount of available carbohydrates. 



"(9) Small gains are not necessarily unprofitable nor are large gains a sure index 

 of profitable food consumption." 



Relative feeding values of timothy, alfalfa, and wild hay, J. 



W. yAKBGEN {Vtnh ^ta. BuJ. 29^ pp. 15-20). — Brief mention is made 

 of a trial with 3 lots of steers fed timothy, alfalfa, and wild hay, 

 resi)ectively, for about 5 weeks. The steers were coniined in stalls and 

 none of them ate well. All lost weight except the lot on alfalfa hay, 

 which gained 27 lbs. 



In a similar trial with sheep confined in small pens the outcome was 

 practically the same, the lot on alfalfa hay being the only one to make 

 any gain in weight. 



The feeding value of cowpea hay, II. L. Bennett and G. B. 

 IRBY (Arhmsas Sta. Bui. 27, p. 79). — A mixture of 20 lbs. of cowpea 

 hay and 13.(5 lbs. of cotton seed per 1, 000 lbs. live weight was fed to 2 

 yearling steers for 37 days and 2 three-year-old steers for 87 days. 

 The yearlings weighed about 475 lbs. at the beginning of the trial and 

 the three-year-olds 94G and 870 lbs., respectively. The yearlings 

 gained 2.0 and 3 lbs. per day, respectively, and the three-year-olds 2.92 

 and 3.14 lbs. 



Narrow vs. wide nutritive rations for horses, J.W.Sanborn ( Utah 

 Ma. Bui. :i(>,pp. ;). — This is similar to an experiment reported in tlie 

 Annual Keport of the vStation for 1892 (E. S. E., 5, p. 77). The wide 

 ration consisted of corn and timothy hay, and the narrow ration of 

 oats, clover hay, and timothy. The nutritive ratio of the former Avas' 

 1:15.2 and of the latter 1:7.8. These were fed to 2 lots of horses
