Effectiveness of various feed supplement on villi characteristics, feed digestibility, and liver-kidney function of broiler chickens
Elly Tugiyanti, Emmy Susanti and Soegeng Heriyanto
Abstract: The research aimed to identify the effect of different feed supplements on the morphometry of duodenum villi, the protein and fat digestibility, and liver and kidney function of broilers. The study used 180 unisex DOCs with an initial body weight of 40.40±2.85 g. The experimental study was conducted in a Completely Randomized Design with six feed supplement treatments, i.e., the non-supplemented feed (negative control), antibiotic (positive control), probiotic, acidifier, phytobiotic, and combined feed supplements. Each treatment was replicated six times. The result showed that feed incorporated with different additives had a highly significant effect (P < 0.01) on the morphometry of duodenum villi (length, width, and crypt depth); a non- significant effect (P > 0.05) on metabolic energy and protein and fat digestibility of broilers, and a significant effect (P < 0.05) on the level of serum glutamic oxaloacetic transaminase and serum glutamic pyruvic transaminase (SGOT and SGPT), uric acid, creatinine, ureic, and blood albumin. Conclusively, feed supplements consisted of probiotics, acidifiers, probiotics, and their combinations have increased the size of duodenum villi, and the performance of liver and kidneys of broilers much better than antibiotics alone. Although, this study reported found that these supplements could not increase protein and fat digestibility.
