MAHUAL OF CATTLE-FEEDING. 



nitrogenous ration, consisting of hay and beans, in sncli 

 quantity as just to maintain tlieir weight and condi- 

 tion. Two other lots (I. and II.) received a less quantity 

 of a ration poorer in protein, so that their average weight 

 per head decreased in 121 days from lOlA lbs. to 97 lbs., 

 while a fifth lot (T.) received still less of a still poorer fod- 

 der, and decreased in average weight per head from 101.1 

 lbs. to 89.3 lbs. Lots I. and II. were fed with straw and 

 mangolds, and lot V. witli about two-thirds hay and one- 

 third oat-straw. 



The amount of wool produced by each lot was the fol-

Lots III. and lY., in which the original well-fed condi- 

 tion was preserved, produced the most w^ool, and judging 

 from the experiments already described, it is probable 

 that, had the fodder been increased so as to fatten the 

 animals, no greater growth of wool woxdd have taken 

 place. 



In lots I. and II. the poorer fodder had as its effect a 

 lessened growth of wool, while in lot V., in which the fod- 

 der was still poorer, the growth of wool continued, but at 

 the expense of the body, which decreased decidedly in 

 weight.
