Influence of Sophora koreensis on the meat quality and growth performance of Korean native chickens

초록

The purpose of the current research was to determine the impact of Sophora koreensis (SKS) on Korean native chickens' (KNC) antioxidant status, meat quality (MQ), and growth performance at various levels (SKS0: basal diet without SKS, SKS1: basal diet + SKS of 10 mg/kg diet, SKS2: basal diet + SKS of 20 mg/kg diet, and SKS3: basal diet + SKS of 30 mg/kg diet). With the addition of SKS, there was a decrease in the level of malondialdehyde and an increase in the levels of catalase, superoxide dismutase, and total antioxidant capacity in the blood and leg muscle. Leg muscles displayed higher 3-ethylbenzothiazoline-6-sulfonate-reducing activity in the SKS-supplemented groups. The SKS-supplemented treatments demonstrated an increased breast muscle capacity to retain water as well as a decreased cooking loss, improved pH, and increased shear force. Inclusion of SKS in the diet was found to increase spleen and bursa of Fabricius weight and body weight gain, and reduce feed consumption and abdominal fat. The SKS-supplemented groups showed a decrease in corticosterone levels and oxidative stress, and an improved antioxidant status and meet quality. In conclusion, SKS-supplementation can increase the antioxidant potential and performance of KNC.
