BROILER-CHICKENS' INTERIOR INDEXES WITH THEIR PRE-SLAUGHTER HOLDING OUT IN SPECIAL SETTLERS

Abstract

A unique experiment was conducted which point was that contrary to the common technology, when poultry (broiler-chickens) were delivered to a slaughter unit directly from cages (18 chickens each) through the upside-down method, we introduced the fragment of pre-slaughter holding the poultry out for 24-48 minutes into the technology. Herein the chickens are in their cages when delivered to a slaughter unit, they are taken out of the cage individually thus excluding the stress factor and possible traumas: hurts, extremity fractures and bruises. The technology concerned pursued the following goals: stress-free (transporting) technology for poultry; possible bowel emptying that largely facilitates further drawing of the poultry, etc. Technological stress experienced by poultry prior slaughtering in the period of catching, loading and delivery (transporting) causes continuous excitation, slows down exsanguinations, which produces a substantial effect on the quality of carcasses. When transporting the poultry to a slaughter unit, thermal stress effect arises as a result of overcrowding. Even a short-time thermal stress causes changes in acid-alkali balance in the blood and damage to muscle cells intactness. The changes concerned make meat juice losses increase after coating and blood spots emerge, which affects meat quality. The technology suggested is protected by positive decision regarding the application for invention № 2013144181/13 (068119) of October 17, 2013.
