growing animals. Straw and hay are particularly poor in 

 phosphoric acid, and as bran and oil-cake are particularly 

 rich in P^O^ one of these substances should be given to young 

 and growing animals and animals in milk along with hay or 

 straw. 



1.104. So the scientific farmer should look not only to the 

 albuminoid ratio, but also to the mineral requisites of food 

 he chooses for his various livestock, and he should consider 

 such other circumstances as cleanliness, flavour &c., which 

 are valuable aids to digestion. 



1.105. F r calculating the total nutriment contained in 

 a food-stuff, the proportions of fibre, ash, and moisture con- 

 tained in it, are ignored, though, as we have just said, they 

 are not without value. The values of albuminoids and of 

 carbohydrates are assumed to be equal. The fat contained 

 in the food stuff is calculated as being 23 times as valuable 

 as either the carbohydrates or the albuminoids. To as- 

 certain, for instance, the nutrient value of paddy-strav, which 

 contains 40*65 per cent, of carbohydrates, 1-78 per cent, of 

 albuminoids and 2*19 per cent, of fat, one has simply to add 

 together, 40*65, ry8 and (2-19 x 2-3), the result coming 

 to 47-467. 



1.106. Although chemical analysis gives no exact idea as 

 to the digestible and other practical value of fodders, yet the 

 following table will be found of some use in determining the 

 merits of fodders :
