 on the composition of milk, manufacture of butter and cheese, and related 

 topics. 



On the value of soy bean cakes and soy bean meal for feeding milch cows,

 2 Swedish dairy farms, with 3 groups of G cows each at each farm. Com- 

 parison between sunflower seed cakes and soy beau cakes or soy bean meal 

 (extracted) showed that both these feeds are well adapted for feeding of 

 dairy cows, even in quantities of 1.5 to 2 kg. per head daily; larger quantities 

 caused an off flavor in the butter. In feeding value 0.9 kg. soy bean cakes or

Experiments with sugar beet pulp, N. O. H. Bang and A. Y. Lund {licr. K. 

 Vet. og Landbolidjskolc.'i Liih. LdiKh'ihoiioni. Forniig [Copenhagen^, 65 {1909), 

 j)p. 62). — A report of experiments in preserving beet pulp in trench silos and in 

 feeding botli fresh and siloed beet pulp. 



The silo experiments were made at ii different farms and were continued for 

 a period of 3 years. The fresh pulp was placed in trenches in the field, about 

 'U yds. wide and 15 in. deep, the length varying according to the amount of 

 available pulp. The quantities of pulp ranged from 38 to 54 tons in the 

 different trials. It was weighed and sampled as filled in the trenches and 

 promptly covered with a layer of soil, generally about 6 in. thick, either on 

 the day of filling, or the following day at the latest, and left for 2 to 18 months 

 in the different trials before the second sampling and weighing took place. 

 The quantity of the siloed pulp was excellent in all cases, a result brought 

 about, in the author's opinion, largely by the promptness with which the pulp 

 was covered with soil. It is noteworthy that the nitrogen in the pulp was 

 practically all in the form of all)uminoids, and that the water content of the 

 siloed pulp was always ab(>ut ().."> per cent lower than that of the correspond- 

 ing fresh i)ulp. The losses observed in gross weight, dry matter, and nitrogen 

 are summarised in the following table:

Pulp in the fresh and siloed condition was compared with mangels (Barres) 

 in separate trials with milch cows conducted on 2 different farms, the cows 

 being separated into 2 lots of 10 each. Equal amounts of dry matter in the 

 pulp and in mangels were fed, and the quantities were larger than would 

 ordinarily be used by Danish farmers, being, on the average, 46.1 lbs. mangels 

 and 61.8 lbs. pulp per head daily. 



The results of the various trials showed that the roots and the beet pulp 

 possess very nearly the same feeding value, the beet pulp having a slight
