DAIRY FARMING DAIRYING. 873 



From this study it was concluded that nature lias made ample provision in 

 supplying a generous store of food to keep the bahy chick well nourished until 

 the brood has hatched, and that this supply of nutrients is sulhcient to carry 

 nutrition on until the bird becomes strong. " From the study of the rapidity 

 of absorption of the abdominal yolk it appears clear that if baby chicks be fed 

 as soon as hatched there is likely to be trouble. If the stomach, gizzard, and 

 intestines become gorged with food it is certain to place more or less pressure 

 on the al)domiual nerves and blood and lymph vessels, and thus the function 

 of these vital structures will be interfered ^\■ith and in some cases cause death." 



Five experiments were run in which the baby chicks were left in the nursery 

 tray until they were 72 hours old. They were then placed in outdoor brooders 

 and given nothing but buttermilk to drink for the next 24 hours, and during 

 the next 24 hours (the fifth day) were given only two light feeds with the 

 milk. On the sixth day they were placed on full feed. These chicks throve 

 better and were stronger and more resistant to chick troubles than their 

 controls. 



It is suggested that in the case of sitting hens it is advisable to give milk 

 the first day after taking the hen from the nest and light feed for the next 

 two days, after which the chicks may be placed on full feed with safety. 



By using the combination sitting and brooding coops the hen may be fed 

 from a high can, such an an oyster can, and the baby chicks fed in their com- 

 partment, as desired and without being interfered with by larger fowls or the 

 mother.

 pp. 334-^336). — This article rep<jrts experiments in the economical feeding of 

 dairy cattle in Denmark, in which the value of oil cake, molasses feed, beets, 

 and straw was demonstrated. 



The utilization of beets in cattle feeding, L. Malpeaux {Vie Agr. et Rurale, 

 6 {1916), No. 2, pp. 27-33, figs. 4)- — In feeding experiments with dairy cows it 

 was found that the feeding of whole beets produced a somewhat larger yield 

 of milk and milk fat than when chopped beets were fed, this increase probably 

 being due to more complete mastication and utilization. 



The utilization of cassava flour in the feeding of dairy cattle, J. E. Lucas 

 {Bill. Econ. Gouvt. Gen. Madagascar, 15 {1915), I, No. 1, pp. 67-71). — The par- 

 tial substitution of cassava flour in the ordinary grain ration for dairy cattle 

 resulted in an increased milk and milk fat yield and in a greater live weight 

 of the animals so fed.
