Slaughter house waste:

Slaughter house waste Slaughter  is a facility where animals are killed for consumption as food products. Anything which is not indented for human use is offal it contributes to the waste. Includes feather, gut, bone, blood, etc The different slaughterhouse by-product include feather meal, blood meal, meat meal, bone meal etc.

Feather meal:

Feather meal Fresh feathers contain about 80% crude protein. Keratin – tough, fibrous, insoluble protein. Sulphur containing amino acid – cysteine . Strong disulphide bonding – Digestibility less than 5%.

PowerPoint Presentation:

Processing methods a) low pressure(<207kpa) at 130 0 c for 150 min. b) high pressure (>207kpa) at 145 0 c for 30 min. The material is dried at 60 0 c and ground. True metabolizable energy for feather meal – 3637kcal/kg on dry matter. The digestibility can be increased up to 50 – 70 %. it may be included in diets at levels of 5 – 10%.

Blood meal:

Blood meal Fresh blood coagulates quickly and deteriorates. Immediately after collection preservation is necessary. Preservation done by, a) adding formic acid, salt, sulphuric acid and potassium metabisulphite . b) spray drying : blood first evaporated into 40 – 50% solids in vacuum (49 0 c) – after sprayed into hot air stream of 316 0 c .

PowerPoint Presentation:

Digestibility ranges between 85 – 97 %. The metabolisable energy is 3440 kcal/kg. Blood meal is rich in lysine and leucine . The application level is in the range of 5 – 10%.

Meat by-product meals:

Meat by-product meals Scrap from meat processing and slaughter house. Carcasses of dead animals. They are classified in to, a) Meat meal b) Meat and bone meal Meat meal contains carcasses of dead animals. Meat and bone meal does not contain carcasses of dead animals and phosphorous content is high.

PowerPoint Presentation:

Metabolisable energy : a) meat meal – 2837kcal/kg b) meat and bone meal – 2949kcal/kg. Recommended inclusion rates meat meal - 15 – 20 % meat and bone meal - 10 – 15 %

Fish silage :

Fish silage Fish silages are liquid feeds manufactured from wastes of fish. They are prepared by either acid silaging or fermenting. The nitrogen fraction contains NPN as well as urea about 20 – 30% of total nitrogen content. The metabolisable energy content is 3394kcal/kg.

PowerPoint Presentation:

The digestibility ranges from 39.9 – 84.4%. Silage from marine material has chemo attractant properties. Fish silage may contain high levels off mercury. Presence of anti nutritional factors thiaminase . Moist silage feeds are made by mixing the silage with a dry binder meal. The inclusion rate is restricted to not more than 20% of the diet.

Applications :

Applications Feather meal replaced the fish meal in the diet of oreochromis niloticus fry. Inclusion rate of 33/66, 66/33 and 100/0 there was no significant difference in the survival. The 100/0 group was smaller than the other groups. The inclusion rates of 25 and 50% of feather meal in the labeo rohita fry showed higher growth. The inclusion of 10% of blood meal in pelleted feed for cage reared tilapia showed good weight gain.

PowerPoint Presentation:

A fish meal analog made from equal parts of feather meal, blood meal and meat and bone meal is used to replace 25, 50 and 75% of fish meal for rainbow trout fingerlings.
