The efficiency of processing is largely dependent on the uniformity of the birds, so that each machine can do a repeated movement with little or no adjustment between birds.

After death, the faster development of rigor mortis increases the likelihood of paler color and reduced water holding capacity and poorer quality of further processed products. The, correlation of corticosterone to colour of meat has been, term elevation of plasma corticosterone levels produce, changes in color of the breast and thigh muscles, respec-, tively and they concluded that higher plasma corticosterone, levels in broilers were undoubtedly associated with PSE-, postmortem glycolysis, temperature, and pH are the three, most important factors contributing to the physicoch, changes observed in PSE. /Helv 26 0 R endobj ���X�x�^�*+�,���3���^N�;c����Φ��1g�+��Aa��b���|Ȳ��f���rD���*��2nYX_h��4���!T�$�WP ͯX�r�d���5kv�1i� �Ï*�\ �H�ל�z(LH�.����&DM[��)$jA���tŁ����f�]�v�,(z7��Ů�� NIR data were subsequently submitted to partial least squares discriminant analysis (PLS-DA) and canonical discriminant analysis (CDA). prohibits atherosclerosis, improves immune function, reduces body fat and improves meat yield (Du and Ahn, increase in protein content and a decrease in the fat content.

These fixed costs are incurred by the plant regardless of the presence of birds, and therefore need to be paid by the production of poultry meat. The production of broiler chickens is the most dynam-ically developing part of the poultry farming sector because of the short chicken rearing time, while main-taining good quality meat and low costs associated with the production (Vissers et al., 2019). Dietary MG significantly (P < 0.05) increased the serum high-density lipoprotein cholesterol, total protein, and superoxide dismutase content in broilers.
