Animal food processing
Overview
utilisation of by products of animals for live stock feeding
Importance of utilisation of By products
The need for efficient treatment of the by- product is based on:
The necessity for their rapid, hygienic disposal thus avoiding decomposition and formation of obnoxious odours. If abattoir by- product are not removed and treated properly, then these will become a serious source of contamination to fresh meat.
The efficient process of abattoir by- product, which secure some economic return on material, which would otherwise be wasted. Therefore, the efficient process of by- product is agreed on both by the meat trade and by public health authorities. So it becomes the obligation of the local authority to see the unsound meat is hygienically disposed off.
Benefits derive from the by-product:
Important of the environmental sanitation
Blood, trimmings, fleshiness, condemned organs and all unused offal’s attract flies, rats, dogs, vermin causing public health nuisance and even danger of spreading diseases. Sanitary disposal of such offal’s often present great difficulties, as offal’s tend to clot
Drinks decomposed rapidly and produce objective odours. Meat slaughtered and kept in unsanitary surrounding created by indisposed offal’s results in products not only of inferior keeping quality.
Healthier and more productive livestock
Use of bones as bone meal, as mineral supplement for stock feed improves the health of the livestock meat, bone and carcass meals contributes as valuable sources of sterile protein food supplement.
Secondary rural industry
The manufacture of by-product of animal origin leads to the establishment of secondary rural industries. Example are tanneries, tallow, soap, glue and bone meal manufacture etc..
Price structure
By- product influence the price of meat and the price paid to the producer for livestock.
Creation of new employment
The conversion of offal’s in to by-products creates new employment and skills not only at the primary industries level but also at the secondary industries levels.
Better crops
The offal’s converted into fertilizers will help in increased the yield of crops
