half a pound ; and as the food consumed may be represented by 5.2 

 lbs. of hay per day and per head, it will follow that 100 of forage 

 had produced 8.58 of live weight. This ratio is too high, however : 

 for these pigs besides the regular allowance had whey and various 

 scraps of which no account was kept ; and we know that whey 

 alone contains a considerable quantity of the representatives both 

 of flesh and fat. 



Baxter came to some interesting conclusions on the growth and 

 fattening of young hogs. Four animals each of the age of nine 

 months weighed at the beginning of the experiment 458.2 lbs. ; 

 twenty-one days afterwards, 620.8 lbs. : increase of weight 162.6 

 lbs., to obtain which there were consumed : 



lbs. ibe. 



Barley 151 equivalent to hay, 250 



Beans 140.8 " 611 



Malt grains 440 " 257 



1229 



So that a quantity of nutritive matter represented by 100 lbs. of 

 hay produced 13.21 lbs. of live weight. 



Assuming the weight of each pig of nine months old before her 

 fatting to have been 29 lbs., the increase per head was 40.6 lbs. in 

 the course of twenty-one days, or at the rate of 1.9 lbs. each. Bax- 

 ter.reckoned the carcass weight, sinking oflfal, at 7.4 per cent. 



One of the pigs between nine and ten months old weighing 159.5 

 lbs., at the end of twenty days weighed 198.8 lbs. : increase in 

 twenty days, 39.3 lbs. ; increase })er day. 1.9 lbs. During these 

 twenty days, the animal had consumed 188 lbs. of barley, equivalent 

 to 314 lbs. of hay. The increase would consequently give for every 

 100 lbs. of hay consumed an increase of live weight of 12.52, say 

 12.i lbs. 



Arthur Young, by keeping pigs of a year old on peas-meal, obtain- 

 ed the following results. 



No. 1 weighed 99.0; 85 days afterwards 157.5; gain 58.5; per day 1.678 

 No. 2 " 91.7; 42 " 145.4; 6.3.7; " 1.876 



No. 8 " 86.6; ft? " 189.4; 62.8; " 0.836 



I shall hero give two sctIcs of f)bservations made at Bechelbronn 

 on the fattening of hogs. September 6th, 1841, seven hogs, aged 

 fifteen months each, already in good condition, were put up to fatten. 

 They had hitherto had the usual hog's food — sour milk and boiled 

 potatoes after weaning , l>y and by from 11 to 15 lbs. of potatoes, 

 *whey, and dish washings. The seven porkers weighed 1691.8 lbs. ; 

 or 241.67 lbs. each. The increase had been at the rate of 0.528, 

 rather better than half a pound per day and per head, supposing them 

 to have weighed 13.7 lbs. each, at the time of weaning. 



After fattcnln:r. 2iith December, the 7 swine weighed 2101. ft
