Abattoir Practices and Animal Products Technology

IMPORTANCE AND BENEFITS

Importance of utilization of by-products

• The need for efficient treatment of the by-products is based on
• The necessity for their rapid, hygienic disposal thus avoiding decomposition and formation of obnoxious odours.
• If abattoir by-products are not removed and treated properly, then these will become a serious source of contamination to fresh meat.
• The efficient process of abattoir by-products, which secure some economic return on material, which would otherwise be wasted.
• Therefore, the efficient processing of by-products 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 derived from the by-products

• Improvement of the environmental sanitation
  • Blood, trimmings, fleshiness, condemned organs and all unused offals attract flies, rats, dogs, vermin causing public health nuisance and even danger of spreading diseases.
  • Sanitary disposal of such offals often present great difficulties, as offals tend to clot drains, decomposed rapidly and produce objective odours.
  • Meat slaughtered and kept in unsanitary surroundings created by undisposed offals results in products not only of inferior keeping quality but also serving as a potential vehicle for disease transmission.
• 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 contribute as valuable sources of sterile protein food supplement.
• Secondary rural industry
  • The manufacture of by-products of animal origin leads to the establishment of secondary rural industries.
  • Examples are tanneries, tallow, soap, glue and bone meal manufacture, etc.
• Price structure
  • By-products influence the price of meat and the price paid to the producer for livestock.
• Creation of new employment
  • The conversion of offals in to by-products creates new employment and skills not only at the primary industry level but also at the secondary industry level.
• Better crops
  • The offals converted into fertilizers will help in increasing the yield of crops.
