The author draws the following conclusions tentatively: "The nutritive ratio 

 between the limits of 1:3.4 and 1:11.3 had no effect upon the quantity or quality of 

 milk production. One and three-tenths pounds of computed digestible protein was 

 sufficient for a 1,000 lb. cow in full milk, the other conditions necessary to her wel- 

 fare being met. Witliin certain limits the quantity, digestibility, and palatability 

 of the food, and its effect upon the animal's general system was of more importance 

 than the relative amount of digestible protein and carbohydrates the ration con- 

 tained. The individuality of the cows experimented upon is an important factor to 

 be reckoned with in investigations of this kind. The term 'balanced ration' is a 

 very indefinite one and may be misleading." 



Report of the assistant in dairy husbandry, C. B. Laxe [Xeic Jersey Stas. Rpt. 

 1902, pp. 291-327, j>^8. 9). — Notes are given on the 12 kinds of forage crops grown 

 for the dairy herd during the year, data as to yield, cost of production, etc., being 

 tabulated. The average yield of alfalfa for 5 years was 19.32 tons of green forage, 

 equivalent to 4.83 tons of hay per acre. The average cost of production was $26.57 

 per acre. Disking alfalfa proved beneficial. Of the several varieties of corn grown 

 for forage the best yields were made ])y Monmouth White. Data are also given in 

 tabular form for the different soiling crop rotations which have been practiced at the 

 station. Conditions affecting the value of forage crops, such as stage of maturity, 

 palatability, influence upon the flavor of milk, etc., are briefly discussed. 



During the period from May 1 to November 1, when soiling crops were fed, the 

 average yield of the herd for 6 years was 3,457 lbs. of milk and 173.8 lbs. of butter.
