76 EXPERIMENT STATION RECORD. [Vol.41 



and scratch. The chicks averaged 1.24 kg. at 28 weeks and the cockerels par- 

 ticularly were consistently somewhat less vigorous than the controls. Secondary 

 sexual characters and sexual instincts developed normally. Lot 2 had access 

 to dry mash of ground barley, rice, hominy, and oats (in equal parts), and was 

 given a scratch of barley, rice, and hominy. Enough butter fat and gluten 

 flour were added to the mash and scratch to make them equal in protein and 

 fat content to the mash and scratch fed lot 1. Once a day a wet mash com- 

 posed of the grain mixture and protein-free milk was fed. This lot made much 

 less than normal growth, the average weight at 28 weeks being only 809 gm. 

 The external sexual characteristics were rudimentary and the feather tracts 

 were not properly developed. Only 19 survived the 28 weeks. " The chicks of 

 lot 2 seemed to have a good appetite, and while they ate with apparent 

 avidity, yet they always seemed to be in search of something in their feed which 

 they could not find. Regarding their ration, it will be seen that it is satis- 

 factory with respect to every necessary dietary factor except the quality of 

 protein. We are unable at this time to show wherein these proteins are lim- 

 ited, but hope to be able to prove this by experiments which are now in 

 progress." 



Protective feeds for poultry, H. R. Lewis (New Jersey Stas., Hints to Poul- 

 trymen, 7 {1919), No. 7, pp. Jf). — Average weights in successive weeks until the 

 twenty-fourth after hatching are given for two groups of chicks, one grown at 

 New Brunswick, N. J., under customary " normal " conditions without milk 

 products in the diet, the other at Vineland, N. J., for contest purposes, with 

 dried buttermilk in the mash, infertile incubator eggs to eat, fluid buttermilk 

 to drink, and an alfalfa pasture as range. Breeds of the American class and 

 Leghorns are treated separately in each group. 



The Vineland chicks in both cases made distinctly the better growth, were 

 for a considerable period during the second and third months at least 50 per 

 cent heavier than the New Brunswick chicks, and attained the last recorded 

 weights of the latter about a month earlier. The success of the Vineland group 

 is attributed to the generous supply of vitamins in their feed. Poultrymen are 

 advised to consider recent discoveries as to the dietary needs of growing ani- 

 mals. 



[Inheritance of color in Andalusian fowl] (Kansas Sta. Rpt. 1918, p. Jf5). — 

 It is stated that further study of the genetics of Andalusian blue in continuation 

 of work already noted (E. S. R., 39, p. 877) makes it desirable to postulate a 

 fourth factor for feather color, namely, a factor responsible for black lacing on 

 the contour feathers. 



Improvement and conservation of farm poultry (Kansas Sta. Rpt. 191S, pp. 

 43-45, fiff. 1). — The annual egg records of mongrel pullets and of their pullet 

 descendants after three generations of top crossing with pure-bred males are 

 compared. The records of Barred Plymouth Rock grades averaged 207.3 eggs, 

 of Single Comb White Leghorn grades 198 eggs, and of White Orpington grades 

 111.25 eggs. The average records of the great granddams were 104.5, 74.5, and 

 123.5 eggs, respectively. A check lot of mongrels not crossed with improved 

 stock increased their average record in three years from 101.7 to 129.6 eggs. 



The Vineland international eg'g-laying' and breeding contest, H. R. Lewis 

 (Neto Jersey Stas. Rpt. 1917, pp.'177-lS4, 1S5-187 ).—Th\s is a statement of the 

 first year's results of the Vineland contest, presenting certain material not given 

 in a previously noted publication (E. S. R., 38, p. 677), including the individual 

 annual egg records of the 10 hens in each of the 100 pens. 



Report of the second (yearling') year of the Vineland international egg- 

 laying and breeding contest, R. R. Hannas (New Jersey Stas., Hints to Poul- 

 trymen, 7 (1919), No. 4, pp. 4)- — This is a preliminary report of the second year
