 (Pennsylvania Sta. Rpt. 1915, pp. 208-219, pis. 17). — Continuing previous work 

 (E. S. R., 28, p. 171), experiments with 30 head of draft horses, divided into 

 five lots of 6 horses each and fattened for market, gave ttie following results :

At the prices prevailing the ration of shelled corn and alfalfa hay produced 

 1 lb. of gain at the lowest figure, giving a greater profit than any other ration 

 used, while the standard ration of corn, oats, and timothy hay ranked second. 

 Replacing the corn with an equal amount of molasses (2.8 lbs. daily) was not 

 found practical. Molasses is an appetizer and in this amount is not a substi- 

 tute for corn. Silage in the ration caused a lessened consumption of hay and 

 grains, but did not produce so large gains. 



The encouragement and improvement of light horse breeding, 1915—16 

 {Jour. Bd. Agr. [London^, 23 {1911), No. 12, pp. 1194-1202).— This is a brief 

 review of the horse breeding operations of the British Board of Agriculture 

 and Fisheries during the year ended October 31, 1916. 



Poultry-feeding tests, P. C. Bkown {Jour. Agr. [Netv Zeal.], I4 {1911), No. 

 6, pp. 464-468, fig. 1). — Owing to the high price of wheat this experiment was 

 carried out to find substitutes in poultry feeding. 



Two pens of White and two of Brown Leghorns, each pen of 6 birds, were 

 fed during two periods of one year each. All lots the first year were fed 

 pollard, bran, maize meal, and meat and bone meal, two lots wheat, and two 

 lots alfalfa chaff and oats. In the second year alfalfa meal was substituted for 

 pollard in two lots. 



The White Leghorns with wheat in the ration averaged 239 eggs per year 

 and without wheat, 238 eggs, and gave profits per bird of f 1 2s. 6d. and £1 Is. 9d., 

 respectively. The Brown Leghorns with wheat in the ration averaged 243 eggs 

 per year and without wheat, 241 eggs, and gave profits per bird of £1 2s. 9d. 

 and £1 2s. 6d., respectively. In the second year the White Leghorns with 

 wheat laid 159 eggs and without wheat, 173 eggs. The Brown Leghorns 179 

 eggs with wheat and 201 eggs without wheat. The profits per bird were for 

 White Leghorns fed Avheat 13s. 5d. and without wheat 14s. lid., and for Brown 

 Leghorns 16s. 4d. and l8s. 4d. 



From these experiments it appears that wheat and even pollard are not 

 indispensable in the profitable production of eggs. Meat meal may be fed in 

 large amounts, if kept separately so that the hens can eat it as wanted. The 

 quantity eaten is influenced by the number of eggs laid. Alfalfa meal is deemed 

 preferable to the chaffed alfalfa hay and does not require steaming overnight.
