Tenth and Eleventh Annual Reports of the Bureau of Animal Industry ( T. S. 

 Dept. Ayr., Bureau of Animal Jndiislrij lijyts. 1S93 and 1S94, pp. 127).^— An account is

DAIRY FARMING— DAIRYING. 



Investigations on the effect of the seed of common vetch on 

 milk secretion, W. J. Quick [Inaug. Diss. Halle, 1896, pp. 44). — Fol- 

 lowing a general discussion of the value of vetch for cows, a feeding 

 experiment with 3 cows is described in which vetch seed was compared 

 with peanut cake during 4 periods varying from 7 to 15 days in dura- 

 tion, with intermediate periods. The cows were of difi'erent breeding 

 and in different stages of lactation. The feeding trial was not made 

 simultaneously with all the cows, and the composition of the rations 

 was not uniform, as one of the cows was near calving. 



The rations were composed of alfalfa hay, barley or rye straw, beets, 

 palm-nut meal, rice meal, and peanut cake or vetch seed, rye and wheat 

 bran also being added in the case of one cow. The peauut cake and 

 vetch seed were the only varying elements, 5.22 to 5.62 lbs. of vetch 

 seed per 1,000 lbs. live Aveight being fed in comparison with 2.44 to 

 2.72 lbs. of peanut cake. The peanut-cake ration was fed the first two 

 periods, the ground vetch seed the third, and the peanut cake again 

 the fourth period. The yielil, specific gravity, and fat content (by 

 Soxhlet's aerometric method) of the milk were determined, and in case 

 of one cow other determinations were occasionally made. These data, 

 together with the live weight, are tabulated in full. A summary 

 follows.
