THE HOG. 



In the course of fifty-eight days the hogs had consumed :

Eye. 770 equivalent to hay 1141.8 



Peas 1802 " 6209 



Potatoes 4796 " 1861 



Greasy water and whey undetermined 8221.8 



The nine animals gave 1746.8 lbs. of meat, fat and lean, or 75.'3 

 per cent, of their weight as they stood alive ; besides which, 141.9 

 say 142 lbs. of lard were obtained from the internal parts. No\n 

 supposing that in the increase of weight obtained in the course o: 

 fifty-eight days, the fat were to be represented by 29 per cent., the 

 fat fixed would amount to 100.1 lbs. ; while the whole of the fatt} 

 substances contained in the food consumed would not amount to mon 

 than 59.6 lbs. It would therefore be imperative to us, did we main 

 tain that all the fat was obtained ready formed from without, to sup 

 pose that the whey and dish washings administered in indeterminate 

 quantity, had introduced 40.5 lbs. of fat into the bodies of the animals 

 Some experiments which are going on at Bechelbronn at this mo 

 ment will, I trust, settle the question definitively as to whether during 

 the fatting of hogs and other animals there is any formation of fat a 

 the cost of the starch and sugar of the food. 



The observations which I have .made on the fattening of hogs ma] 

 be summed up in these terms : 



The allowance to the hogs in the preceding observations was al 

 ways abundant. To determine the quantity of potatoes consume( 

 each day by a hog in full growth, and whose weight was known, 

 had him weighed at intervals, as well as the potato ration, place* 

 before him at will, which he ate daily, and found that when h 

 weighed :
