Relation of food-consumption to egg-production (Cornell). 



That the number of eggs produced bears a close relationship to the 

 amount of food consumed is shown in the chart (Fig. 8) A and B 

 where it will be seen that the hens which laid the largest number of eggs 

 in a stated period consumed the most food. Periods of large egg- 

 production always appear to be periods of increased food consump- 

 tion, and vice versa. 



It will be noticed that the increase in food consumed precedes, by 

 a few weeks, the increase in production, showing that the fowl fortifies 

 her body by storing up the nourishment from which to produce eggs 

 (A, B, and C). 



A glance at the plotted curves, comparing (B), the weight of the 

 fowls during each period, and (C), the percentage egg-production for 

 each period, will show how uniformly the curve expressing increase 

 and decrease in production follows the curve of increase and decrease 

 in weight. The weight of hen is greatest preceding heaviest egg- 

 production. 



A comparison of the amount of food consumed, the eggs laid, and the 

 weight of flocks of different ages shows that the youngest fowls ate 

 the most food and produced the largest number of eggs. 



The percentage egg-production varies each month, according to 

 the seasons, with remarkable regularity. This is strikingly
