Determination of Performance, Slaughter Characteristics and Tonic Immobility of the Anadolu-T Broiler Genotype

Abstract

This study investigated the body weight, feed consumption, feed conversion ratio, carcass traits, organ weights, and tonic immobility of the Anadolu-T broiler chicken genotype. A total of 66 chicks were used in the study. The Anadolu-T broiler chicks were raised in a free-range system for 42 days. As performance characteristics, body weight, body weight gain, feed consumption, feed conversion ratio, and mortality were recorded in the study. The carcass characteristics and organ weights of the animals slaughtered after 42 days were determined. Additionally, tonic immobility was measured in birds as an indicator of fear. Average body weight values on Day 1, Day 10, Day 25, and Day 42 were determined as 37.7 g, 234 g, 1064 g, and 2598 g, respectively. The average body weight gain from Day 1 to Day 42 was determined as 2560 g. The average tonic immobility value was determined as 164 sec. The average feed consumption of the Anadolu-T genotype between 1 and 42 days was determined as 4873 g. The feed conversion ratio between 1 and 42 days was determined to be 1.90. The average carcass weight ratio of the Anadolu-T broiler chicken genotype was determined to be 75%. The breast meat ratio was determined to be 34%, the back weight ratio 18.5%, the thigh weight ratio 28%, the wing weight ratio 11%, and the neck weight ratio 7.5%. The Anadolu-T broiler chicken genotype was found to have an average weight percentage of 0.98% for the heart, 2.20% for the liver, 0.47% for the spleen, 1.70% for the gizzard, and 0.63% for the pancreas.
