live weight was fed.) The rape-seed cake, wheat meal, rye meal, palm 

 cake, and dried brewers' grains had no particular effect upon milk pro- 

 duction as a whole. The palm cake, although it gave a high percentage 

 of fat, was not satisfactory in other respects. The milk had an oily odor 

 and a pungent taste. 



Feeding experiments with milch cows, J. M. Bartlett (Maine 

 Sta. Bpt. 1896, pp. 37-55). — In these experiments gluten meal was com- 

 pared with cotton-seed meal, silage was compared with grain, and 

 ground oats was compared with wheat bran, and the effect of Xutrio- 

 tone was tested. Six registered Jersey cows were used, and these were 

 divided into 2 lots of 3 each. 



Gluten meal vs. cotton-seed meal | pp. 30-43).— Feeding a constant basal 

 ration, 3 lbs. of gluten meal was compared with 2 lbs. of cotton-seed 

 meal in 3 periods of about 3 weeks each. The composition of the feed- 

 ing stuffs and of the milk, with other data, are tabulated. 



"The data indicate that gluten meal is fully equal to cotton-seed meal when fed 

 in sufficient quantity to make the amount of digestible nutrients equal in each 

 ration. It is not equal to cotton-seed meal pound for pound as a source of protein, 

 as it contains, on an average, about one-quarter less of that nutrient. It makes a 

 very good quality of butter, but slightly softer than that made from cotton-seed 

 meal ration when fed in the quantity used in this experiment." 



Silage compared with (/rain (pp. 43-40).— The silage was the Robert- 

 son mixture, consisting of fodder corn, horse beans, and sunflower 

 heads. Ration No. 1 consisted of 20 lbs. timothy hay, 20 lbs. silage, 

 and 8 lbs. grain. Ration Xo. 2 consisted of 15 lbs. timothy hay, 35 lbs. 

 silage, and 4 lbs. grain. There were 2 periods of 2 weeks each. 



"This experiment, although too limited to be of much value in itself, confirms the 

 results of Professor Robertson's investigations and those obtained from experiments 

 made at this station last year, showing that silage of the quality used can be sub- 

 stituted in part for the grain ration of milch cows without causing loss of flesh or 

 lessening the production of milk. In this case 15 lbs. of silage appeared to equal i 

 lbs. of the grain mixture." 



Ground oats compared with wheat bran (pp. 46-51). — Feeding a con- 

 stant basal ration, 4 lbs. of wheat bran was compared with 4 lbs. of 

 ground oats in 3 periods of about 3 weeks each. 



"These results show a slightly larger yield when oats were fed than when bran 

 was fed. but the differences are not sufficiently large for one to say that oats have a 

 greater feeding value than bran. . . . Their mechanical condition is such that they 

 are equally good to mix with heavier feeds like corn, cotton seed, and gluten meals." 



Xntriotonefor the production of milk (pp. 51-55). — This material is said 

 to be extensively advertised in the State, and the claim made that it is 

 not only a curative agent but a stimulant to the production of flesh and 

 milk. Five Jersey cows, fresh in milk, were fed liberal rations of hay 

 and grain in proportion to their size; and, in addition, in the first, third, 

 and fifth periods, the prescribed amount of Nutriotone was fed, and in
