2. Animal by-products
Animal by-products (ABPs) are entire animal bodies, parts of
animals, products of animal origin or other products obtained
from animals that are not fit or intended for human consumption.
They must be dealt with in accordance with strict regulations
designed to prevent harm to people, animals and the environment.
ABPs are categorized by the risks they pose and the methods
used to deal with them

3. TYPES OF ANIMAL BY-PRODUCTS
-Catering waste (including used cooking oil) from commercial and -
household kitchens
-former foodstuffs of animal origin from food manufacturers and -
retailers
-butcher and slaughterhouse waste
-blood
-feathers
-wool
-hides and skins
-fallen stock
-dead pet animals
-dead zoo animals
-hunt trophies
-manure
-ova, embryos and semen (when not destined for breeding purposes)

4. BLOOD
Blood is a liquid connective tissue that is specialized to deliver
necessary substances to the body's cells and remove wastes from
them
COMPOSITION OF BLOOD
-Red blood cells, also called "erythrocytes," carry oxygen
throughout th blood.
-White blood cells, called "leukocytes," are part of the body's
immune system and help defend the body against pathogens.
-Platelets are cells that aid in blood clotting.
-Hemoglobin
the iron-containing substance in red blood cells that transports
oxygen from the lungs to the rest of the body; it consists of a
protein (globulin), and harem (a porphyrin ring with an atom of
iron at its center).
-Plasma
A clear component of blood or lymph containing fibrin

5. SOURCE OF BLOOD
From slaughter house, different meat industry
BLOOD MEAL
Blood meal is a dry, inert powder made from blood used as a high-
nitrogen fertilizer and a high protein animal feed. N = 13.25%,
p = 1.0%, k = 0.6%. It is one of the highest non-synthetic sources of
nitrogen. It usually comes from cattle as a slaughterhouse by-
product.
Whole blood meal is produced by spray drying at low temperatures,
the fresh whole blood from animal processing plants.

Leucine 10.3 %
Arginine 2.35 %
Glycine 4.4 %

8. PROCESS OF BLOOD MEAL PREPARATION
Different production methods are applied in the industry, but some of the main
processes are following:
1) by-products from slaughterhouses (blood) are transported to the
factories in closed containers
2) the products are minced
3) the "mincemeat" is coagulated by heating (80-90oc)
4) liquid and solid material is separated by pressing,
5A) the solid fraction is dried (110oc),
5b) the wet fraction is heated (105oc) and fat is separated,
6a) the dry product is screened, sterilized (133oc), packed and stored for
distribution,
6b) fat is sterilized (125oc), packed and stored for distribution.
7) the wastewater generated during the process is either treated
completely and emitted to recipient or treated to some extent and diverted to further in
municipal wastewater treatment plants.
8) ventilation air is treated in bio-filters.
9) blood meal from healthy animals has traditionally been used for
animal feed.

10. FUNCTION OF BLOOD MEAL
1. It can be spread on gardens to deter animals such as
rabbits
2. It can be spread on gardens as a composting activator
3. It may also be used as an animal food supplement for
cattle, fish and poultry and is in fact widely used due to the
high lysine content.
4. It is mixed with molasses before use as animal feed.
5. Blood meal is permitted in certified organic production as
soil amendments.
6. Applying blood meal will help plants become green
again
7.It is use as a poultry feed source of high protein.

11. LIMITATION OF BLOOD MEAL
1.It has low digestibility
2. Blood is not available.
3.It is very much costly
4. Preparation technique is very complex
5.It is not use like other feed and etc.
6.Low in calcium and phosphorus
7. It is not recommended for young stock.
8. The meal is unpalatable
