Product Description

PRODUCT DESCRIPTION

Blood meal is a by-product of the slaughtering industry and is used as a protein source in the diets of livestock.

The drying of whole blood from slaughtered animals derives blood meal. The method of drying does affect the nutritional quality of the protein in the meal. The three methods of processing whole blood are batch dry rendering, ring dried rendering and spray died rendering.

Batch dry rendering involves the cooking of whole blood in a jacketed cylindrical cooker that is indirectly heated by steam at a pressure of about **0 kPa. Ring dried rendering involves coagulating the blood by steam heating, the coagulum is centrifuged and dried with hot gas in a ring drier. The process of manufacturing spray dried blood meal is similar to that of skim milk powder which liquid is sprayed inside the warm chamber and then become fine powder instantly.

The ring-dried and spray dried blood meal has a greater content of total and available amino acids and is of better nutritional quality. For example, the availability of lysine as a percentage of the total lysine is *4% to *9% for ring-dried blood meal, as compared to batch-dried meal in which lysine is *2% to *7% available.

DIRECTIONS FOR USE

Blood meal is very rich in protein and amino acids and can be used as a protein supplement in diets for pigs and poultry of all ages. However, because of its low palatability, less than 5% is usually included in diets. Feeding ring-dried or spray-dried blood meal is preferred to batch-dried.
