Effect of fiber source diet supplement on growth performance, carcass quality, oxidative stress and intestinal morphology in Thai native chicken (Pradu Hang dum)

Dietary fiber was used for reduce feed cost in local animal production. However, other advantages effects were interesting to study. Therefore, the objective of this research investigated effect source diet on performance, carcass quality, oxidative stress and intestinal morphology Thai native chicken. A total 300 one-day-old (mixed sex) crossbred chicks (Pradu Hang dum) randomly assigned 5 treatments completely randomized design (CRD). Each treatment had 10 replicates with chickens 6 bird/replicates (1 12 weeks age) given different levels banana stem Napier grass. Treatment diets received as follows a basal diet; 100%, no supplement or control group (CON), 95%, 90% supplemented at 50 g/kg, 100 g/kg (BS 5%, BS 10%) diet, respectively, grass (NG NG respectively. The results study showed that use source: improved growth performance. result benefits increase body weight, improve conversion ratio (FCR) per gain (FCG), gut health by villus height (VH), Villus width (VW) duodenal jejunal small intestine morphology, reduced malondialdehyde (MDA) serum (p < 0.001). In addition, significantly higher thigh meat percentage 0.05) without effecting visceral weight overall percentage.
