Feeding Stuffs in September. [Sept. 



is fairly acceptable to animals, and has a constant composition 

 of about 55 per cent, protein, 4 to 5 per cent, of oil, and not less 

 than 16 per cent, of phosphate of lime. It should not contain 

 more than 12 to 13 per cent, of water and 4 per cent, of salt. 

 Buyers should see that they get a standardised product of about 

 this composition. 



Fish meal of this kind was tested on many occasions during 

 the later stages of the War, and found to be suitable for a great 

 variety of purposes. In using it for all purposes certain facts 

 must be borne in mind. In the first place it contains no carbo- 

 hydrate, and since this is a necessary constituent of the diet of 

 farm animals, fish meal should always be used in conjunction 

 with starchy foods. Secondly, fish meal is so rich in protein and 

 ash constituents that it is not suitable to form more than a small 

 fraction, say, one-eighth to one-twelfth of the whole diet. 



With these reservations it may be used successfully for all 

 kinds of stock — cattle, sheep, pigs, and even horses. Special 

 notes on the use of fish meal appeared in this Journal for August, 

 1919, p. 480, and August, 1920, p. 414. 



Note. — In the issue of this Journal for August (page 415) was 

 given a " Standard Analysis of White Fish Meal," to which the 

 Association of Fish Meal, Fish Guano, and Fish Oil Manu- 

 facturers — representing nearly all the manufacturers of fish meal 

 in Great Britain — have agreed to conform. An error in printing 

 occurred in this issue, and the analysis is here reproduced in 

 its correct form.
