USE OF FEEDINGSTUFFS 



The use of bulk feed deliveries continues to increase. This is a way of cutting feed costs 

 when proper facilities are available for delivery and storage of the feed. 



It is not within the scope of this bulletin to make recommendations regarding the use of com- 

 mercial feedingstuffs. The Department of Dairy Husbandry and the Department of Poultry Hus- 

 bandry are continually studying feeding problems. The following publications which discuss feeds 

 and feeding from one viewpoint or another are available free of charge to residents of New Hamp- 

 shire. Requests should be addressed to: Mail Service, University of New Hampshire, Durham.

Inquiries occasionally are made regarding a method of calculating the protein, fat, or fiber 

 contentof a home-mixed feed. Thereare tables available, such as those in Morrison's book "Feeds 

 and Feeding, " which give the average chemical analysis of feed concentrates, roughage and silages. 

 It should be pointed out that the chemical analysis of aparticular lot of an ingredient may be some- 

 what above or below the average figure shown in the table. This fact must be taken into consider- 

 ation in fixing guarantees. The following example shows how the protein content of a feed may be 

 calculated:
