Study on growth performance, meat quality, carcass quality and sensory evaluation of Pradu Hang Dam Chiang Mai 1 chicken raised with commercial diet for native chicken and mixed diet

Abstract

The aim of study was to compare the growth performance, meat quality, carcass quality and sensory evaluation of Pradu Hang Dam Chiang Mai 1 chicken raised with commercial diet for native chicken and mixed diet. Two hundred and forty Pradu Hang Dam Chiang Mai 1 chicken with 1-day old were divided by 2 treatments with 3 replications (40 chickens per each replication) in Completely Randomized Design (CRD). Chickens were given food and water ad libitum throughout the experimental period (10 weeks). The study showed that Pradu Hangdam chicken raised with a commercial diet for native chicken had higher growth performances, live weight, feed intake and carcass quality than chicken raised with mixed diet (P<0.05). While the tenderness of breast muscle of Pradu Hang Dam chicken raise with mixed diet was lower in shear force value than chicken raised with a commercial diet for native chicken (P<0.05). Furthermore, the result showed that male chicken was higher in shear force value than that of female in both breast and thigh muscle (P>0.05). However, the water holding capacity in terms of cooking loss and thawing loss did not affect in both diets but had effect in gender (P<0.05). In addition, the sensory evaluation score included tenderness, juiciness and overall acceptability was higher in Pradu Hang Dam chicken raised with mixed diet group than chicken raised with commercial diet for native chicken (P<0.05). Therefore, the results of this study would provide useful information to support decision-making for farmers who interested in raising Pradu Hang Dam chicken Chiang Mai 1. In order to adapt and develop the commercial of Pradu Hang Dam chicken Chiang Mai 1 for sustainable commercialization.
