average about % of a pound daily gain. According to Lawes 

 and Gilbert: "Sheep on good fattening food, such as oil cake 

 or corn, with chaff and roots, will consume weekly about 4.75 

 Ibs. oil cake, 4.75 Ibs. of hay, and about 70 Ibs. of roots, for 

 every 100 Ibs. of their live weight. 



"When fed as above, they will consume every week about 1 / 7 

 of their own weight of the dry substance of food; that is, after 

 deducting the moisture it contains. 



"Sheep well fed and under cover will increase about 2 per 

 cent, upon their weight; that is to say, 100 Ibs. live weight will 

 increase from 1.75 Ibs. to 2 Ibs. per week. 



"To increase 100 Ibs. in live weight, sheep will consume about 

 225 Ibs. of oil cake, or corn, 225 Ibs. of hay (chaff), and from 

 3,000 to 3,750 Ibs. of roots. 



"The increase of a fattening sheep is at the rate of about one 

 pound live weight to eight or nine pounds of the dry substance 

 of the food consumed."
