subdivided into two groups ; (A) Control group with rations of inilk serum, 

 skim milk and barley ; (B) Test group in which the serum, m.ilk or barley 

 are in part or in different proportions replaced by lucerne, vetches or green 

 clover. The results may be summed up as follows : 



i) Green forage may form part of the daily ration to the extent of 

 10 % of the total weight without the gro\\1h of the animals suffering in 

 anv way. 



The nutritive value of fresh hay depends on the weather and is gener- 

 ally higher in summer than in winter crops. 



2) Lucerne and clover have nearly the same value, so thst 2.2 lbs. of 

 barley may be replacd by 15.4 to 16.5 lbs. of lucerne or clover. Vetches, 

 owing to the lower percentage of dry substance, are much below the other 

 two pulses ; 19.8 to 22 lbs. of vetches correspond to 2.2 lbs. of barley. 



3) Steeping and cooking the forage have no marked influence on 

 the daily growth of the animals, as appears from the following table :

Finally it w^s remarked that the dead weight is greater in the pigs 

 of the test group partly fed with green forage.

7S1 - Experiments on the Necessity of adding Gravel to Poultry Food. — BtJzAs cy., in 



Baromfitenycxztuk (Poultry Keepers), Year XI, Xo. 6, pp. 68- 70 Bu(lai)est, April 1916. 



In order to ascertain whether there is any advantage in adding small 

 gravel to the food of fattening chickens, as is done by most Hungarian 

 poultrj^ preeders, Mr. A. Zaitschek, Chief Royal Chemist, undertook a 

 series of experiments. Their object was, at the same time, to gain further 

 knowledge about the gizzard of graminiverous birds, and ascertain w^hether 

 the small gravel always found in the gizzard of poultry is an indispensable 

 mechanical factor in digestion. 



The tests covered 3 groups of 6 chickens, kept from the i..|.th Septem- 

 ber to the 28th November on a diet of maize, partly whole, partly ground. 

 While group II was given carefully screened maize free from all gravel, group I
