Abstract:
Thai Indigenous chicken is animal economics. This study aimed to development products to improve performance of Thai Indigenous chicken (praduhangdum). The case study 2 experimental compounds: Experimental 1 development and this study to examine the effect of feed additive on performance of Thai Indigenous chicken hens. A total of 400 indigenous chicken hens (praduhangdum) were randomized to 4 treatments, each treatment with 4 replicates of 25 chicks each. The experimental diets consisted of 4 treatments, control group, diet supplemented with P. mirifica 0.01% with S. Cerevisiae 0.2% and 0.5% of banana, diet supplemented with P. mirifica 0.02% with S. Cerevisiae 0.2% and 0.5% of banana and diet supplemented with P. mirifica 0.03% with S. Cerevisiae 0.2% and 0.5% of banana. Thai native hens were given access to feed and water was provided twice a day (7 am and 3 pm). The results showed that diets supplemented with 100 g of P. mirifica with S. Cerevisiae 0.2% and 0.5% of banana resulting in the egg production (%), hatchability (%), Fertility (%), egg mass and Feed conversion ratio of egg which is higher than control group (P<0.05). And feed intake (FI) less than control group (P<0.05). Therefore, the diets supplemented with 0.01% of P. mirifica with S. Cerevisiae 0.2% and 0.5% of banana resulted in improved performance. Experimental 2 The effect of feed additive on performance of Thai native (praduhangdum). A total of 1,200 birds were randomized to 4 treatments, each treatment with 4 replicates of 75 chicks each. The experimental diets consisted of 4 treatments, control group, diet supplemented with T. triandra 0.02% with S. Cerevisiae 0.2% and 0.5% of banana, diet supplemented with C. asiatica 0.02% with S. Cerevisiae 0.2% and 0.5% of banana and diet supplemented with P. amaryllifolius 0.02% with S. Cerevisiae 0.2% and 0.5% of banana. Thai native was given access to feed was provided twice a day (7 am and 3 pm). The results showed that diets supplemented with 0.02% of P. amaryllifolius with S. Cerevisiae 0.2% and 0.5% of banana resulting in the body weight (BW), daily body weight gain and Feed conversion ratio (FCR) which is higher than control group (P <0.05). Therefore, the diets supplemented with 0.02% of P. amaryllifolius with S. Cerevisiae 0.2% and 0.5% of banana resulted in improved performance.
