vi PREFACE 



As there is not at the present time an English 

 book which gives concisely and clearfy the informa- 

 tion which a farmer or agricultural student ought to 

 possess, I have gladly agreed to the following trans- 

 lation being made by Dr. Goodwin. In Part I will 

 be found the main principles upon which the theory 

 of feeding is based, then follows in Part II a short 

 descriptive account of the different feeding-stuffs, in 

 which more attention has been paid to the suita- 

 bility and uses of the various classes than to the 

 percentage amounts of nutrients which they con- 

 tain. This second part also includes the methods 

 used in the conservation and preparation of feeding- 

 stuffs, and is followed in Part III by the conditions 

 which should be observed in the feeding of the 

 different kinds of domestic animals. The tables 

 needed for the calculation of rations, with a few 

 remarks upon the method of using them, are placed 

 in the Appendix. 



I sincerely trust that this edition will gain as 

 favourable a verdict as the original has done both 

 from practical men and from students of agricul- 

 ture and veterinary science.
