A study on the evaluation of Indonesian local microbial phytase supplementation and its impact on broiler chicken performance, metabolic energy utilization, ileal histomorphology, and meat and bone mineralization

The effect of local Indonesian microbial phytase, derived from L. plantarum A1-E extracted the small intestine free-range chickens and C. tropicalis TKd-3 obtained fermented soybean tempe, on growth performance, metabolizable energy, ileal histomorphology, meat bone mineralization in broilers is subject evaluation this study. A total 140 day-old broiler chicks were divided into four treatments, five replicates, seven each replicate. research was carried out for 28 days. experimental groups consisted a basal diet without phytase (FA) serving as negative control, supplemented with 500 FTU/kg (FB), (FC), commercial positive control (FD). results revealed that performance index increased by FB FC treatments (P<0.05), treatment exhibited tendency to enhance energy (P=0.06). result ileum histomorphology showed villous height, ratio height crypt depth, surface area (P<0.05). highest mineral content phosphorus (P), magnesium (Mg), iron (Fe) breast Furthermore, calcium (Ca), P, Mg, zinc (Zn), Fe thigh found tibia demonstrated exerted significant (P<0.05) content. In conclusion, due supplementation. Besides that, improved villus, absorption minerals, meat, minerals deposition tibia.
