570 EXPERIMENT STATION RECORD. [VoL 36 



Except during the first 28 days, when the fillies were allowed as much grain 

 and hay as they would consume, the grain was restricted In amount so that 

 the hay eaten amounted to 1 lb. or more daily per 100 lbs. of live weight. 



The results indicated that a liberal proportion of well-cured legume hay 

 should be the foundation for feeding young growing horses, and that enough 

 grain should be fed to produce good growth. It is also indicated that as the 

 individual becomes older the proportion of grain to hay may be decreased and 

 still obtain good gains. In this experiment 0.5 lb. of grain daily per 100 lbs. 

 of live weight was sufficient for proper development except for a short time 

 when the pasturage was scant. 



The average daily gain per head during the first winter was 1.94 lbs., during 

 the summer 0.85 lb., and during the second winter 1.22 4bs., or 1.33 lbs. for 

 the 518 days. The total gain per head was 690.5 lbs. and the average increase 

 in height 7.96 in. The average total feed consumed during the whole experi- 

 ment was 45.35 bu. of corn, 79.36 bu. of oats, 2.58 tons of alfalfa, and 0.8 

 acre of pasture per head. The average amount of feed required to produce a 

 pound of gain was during the first winter 5.67 lbs. of grain and 4.27 lbs. of 

 hay, and during the second winter 9.23 lbs. of grain and 13 lbs. of hay. The 

 average weight of the fillies at one year was 1,112 lbs. and at two years 

 1,548 lbs. 



On the basis of $11 per ton for alfalfa hay, 50 cts. per bushel for corn. .35 

 cts. per bushel for oats, and $10 per acre for pasture, the cost per pound of 

 gain was 7.98 cts. for the first winter, 16.04 cts. for the summer, and 16.31 cts. 

 for the second winter. On the same price basis the average total cost of feed 

 per head was $56.07 for the year and $86.88 for the year and five months. 



Fourth annual international egg laying contest, W. F. Kirkpatkick and 

 L. E. Card {Connecticut Storrs Sta. Bui. 87 (1916), pp. 197-2U, figs. 25).— In 

 experimental pens in connection with this contest skim milk was substituted 

 for the beef and fish scrap in the regular ration. Fifty hens oh the regular 

 ration laid 7,380 eggs and 50 hens on the milk ration laid 8,359 eggs. The milk- 

 fed hens consumed 2,000 qt. of milk, valued at $20, and those on the regular 

 ration about 350 lbs. of beef and fish scrap, at a cost of $9. 



In the main contest the Rhode Island Red eggs averaged 1.6 lbs. per dozen, 

 Plymouth Rock eggs 1.56 lbs., 'White Leghorn eggs 1.52 lbs., Wyandotte eggs 

 1.47 lbs., and miscellaneous breeds, including Light Brahmas, American Domi- 

 niques. Brown, Buff, and Black Leghorns, Silver Campines, Light Sussex, 

 Salmon Faverolles, White Orpingtons, and Buttercups, 1.56 lbs. The average 

 weight of the eggs for all of the breeds was 1.54 lbs. per dozen. The per- 

 centages of broody hens averaged from 5.9 for the White Leghorns to 69.6 for 

 the Wyandottes, the average for all breeds being 37.2. The average number 

 of days lost each broody period was 20.6. The number of eggs laid per month 

 by the 1,000 hens in this contest varied from 4,070 in November to 18.280 in 

 May. Over 34 per cent of the total eggs for the year were produced in March, 

 April, and May. 



In the operation of trap nests the number of eggs laid outside the nests 

 varied from 8 in a pen of Orpingtons to 140 in a pen of Wyandottes, the average 

 percentage of unidentified eggs for all the breeds being 3.73. Weight curves 

 showed that all breeds were heaviest on March 1, and, with the exception of the 

 first weighing on November 1, they were lightest on May 1. 



The 1,820 birds involved in the third (E. S. R., 33, p. 672) and the fourth 

 contests consumed an annual average of 44.4 lbs. of gi-ain per hen or about 2 oz. 

 per day. The feed cost per dozen eggs in the fourth contest was 12.7 cts. for 

 the Leghorns, 12.9 cts. for the Wyandottes, 15.3 cts. for the Rhode Island 

 Reds, and 16.2 cts. for the Plymouth Rocks, the average for all breeds being
