Analyses of spurry hay and seed, B. Boggild (Ugeskr. Landm., 



42 (1897), pp. 55-57). — Spurry (Spergula arvensis) is used to some extent 

 in western Denmark as a food for milch cows and pigs. The ground 

 seed is also fed. According to reports, as much as 6.6 lbs. of seed per 

 bead daily is sometimes fed to milch cows without producing any bad 

 effects on tbe dairy products. Spurry is best adapted to light soils and 

 may be grown on poor sandy soil or marsh land. The amount of seed 

 required per acre is from 15 to 18 lbs. The average yield is 1£ tons of 

 hay per acre. Analyses of spurry hay and seed are given in the fol- 

 lowing table:

Molasses pulp, a new feeding stuff, L. F. Nilson (K. landt. A had. 

 ffandl. Tidskr., 35 (1896), pp. 218-222).— The dried beet pulp from beet- 

 sugar factories lias been used to some extent as a cattle food by Swedish 

 farmers, and with very satisfactory results, it may be fed in the fol- 

 lowing quantities per head and per day : M ilch cows 3 to 1£ kg., fattening 

 steers 5 to 7£ kg., working steers 4 to 6 kg., fattening sheep 0.3 to 1 kg., 

 young cattle 1 to 2 kg. 



The expense of drying the pulp is given as 1 cts. (15 ore) per 100 kg., 

 and the price paid at the factory for the feed, 61.07 per 100 kg. (220 lbs.). 

 A sample analyzed at the Alnarp chemical laboratory had the following 

 composition: Water 9.38 per cent, ash 1.18, crude protein G.oT, ether 

 extract 0.3, crude fiber 21.58, and nitrogen-free extract 51.89 per cent. 



In order to utilize the large quantities of molasses which accumulate 

 every season at beet-sugar factories, the method of E. Wiistenhagen 1 

 was adopted at the Trelleborg sugar factory (Sweden), and a dry cattle 

 food of good keeping quality was made by drying the pulp with molasses. 

 The following analysis shows the chemical composition of this feed:
