Abstract
Numerous efforts have been undertaken to develop suitable alternatives in order to counteract the anticipated drawbacks associated with the ban of antibiotic growth promoters (AGPs). The research purpose is to carry out the possible effect of mannan-riched fraction (MRF) and probiotic enhanced water as natural growth promoters (NGPs) on performance, relative organ weight, serum blood biochemistry, intestinal properties, and intestinal micro flora. 320 one-day-old Arbor Acres broiler were randomly allocated to 4 dietary treatments and 4 replicates of 20 birds per cage. four treatments used for research were dietary with control (T0), basal diet + MRF 80 g (T1), Drinking water + 2 mL/L combination feed additive (T2), and basal feed + MRF 80 g+ drinking water 2 mL/L combination feed additive (T3). The results showed that using mannan riched fraction (MRF) and combination with probiotic-enhanced liquid acidifier presented significant difference (P > 0.05) on body weight gain at 1-28 days and intestinal properties. On the blood biochemistry, the effect of supplementation began to reduce the amount of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) at 21 days periods. To sum up, the addition of mannan-riched fraction and combination with probiotic enhanced liquid acidifier doesn’t impacted on growth performance, and serum blood biochemistry but give significant effect on intestinal properties of broiler.
