486 Agricultural Chemistry. — Pig Feeding. 



These five pens were devoted to the trial, as pig-food, of dried 

 Newfoundland cod-fish — an article which could be supplied in 

 large quantities, and at a moderate price, were it found available 

 for this purpose. The experiments were so arranged as to ascer- 

 tain in what proportions it could be most advantageously mixed 

 with other foods : the dried cod-fish containing, as will be seen 

 in our Table of Composition, a much higher percentage of nitro- 

 gen than any other current pig-food. Hence, if it were found 

 otherwise available, it would yield a manure of corresponding 

 richness. 



It should be stated, that during the preliminary period, the 

 pigs in Pens 1, 2, and 3 of this Series were supplied with the 

 same food as had been given in the 12 pens of the First Series ; 

 namely, one part Bean and Lentil mixture, one part Indian corn, 

 and two parts Bran. Pens 4 and 5, however, were provided, 

 during their preliminary period, with half a pound per pig per 

 day of the dried Cod-fish, and were allowed to take ad libitum of 

 a mixture of one part Bean and Lentil meal, one part Barley-meal, 

 and one part Bran. The Cod-fish was in all cases prepared by 

 boiling in water ; and a portion of the other food was then stirred 

 in with the soup thus obtained. It is scarcely necessary to men- 

 tion that in all the experiments with pigs the food was mixed 

 with water before it was put into the troughs. 



The allowance of food to the several pens of the Third Series 

 was as follows : — 



Pen 1. 2 lbs. of dried Cod-fish per pig per day: with a mix- 

 ture of equal parts of Indian meal and Bran, ad 

 libitum. 



Pen 2. 2 lbs. of dried Cod-fish per pig per day ; with Indian 

 meal, ad libitum. 



Pen 3. Cod-fish, and a mixture of equal parts of Indian meal 

 and Bran, each ad libitum. 



Pen 4. 1 lb. of Cod-fish per pig per day ; with a mixture of 

 2 parts Barley-meal and 1 part Bran, ad libitum. 



Pen 5. lib. of Cod-fish per pig per day; with Barley-meal, 

 ad libitum. 



Table X. gives the increase of each pig, and of each pen, upon 

 these five dietaries, during each fortnightly period, and the total 

 periods of eight weeks.
