Synergistic effect of non starch polysaccharide enzymes, synbiotics and phytase on performance, nutrient utilization and gut health in broilers fed with sub-optimal energy diets

Abstract

Aim:In view of the ban on antibiotic growth promoters (AGPs), an attempt was made to explore the possibility of harnessing synergistic effect of non starch polysaccharide (NSP) enzymes, synbiotics and phytase on performance, nutrient retention, gut health and histology of broilers fed with corn-soybean meal based low calorie diets. Materials and Methods:A total of 150 a day-old broiler chicks were weighed, wing banded and randomly distributed into five experimental groups, six replicates per group and five birds per replicate and raised in electrically heated battery brooders. Evaluated the synergistic effect of the NSP enzymes, synbiotics and phytase alone or in combination, supplemented to cornsoybean meal based broiler diet, low in energy concentration (Basal diet (BD)) (-225 kcal lower metabolizable energy than standard diet (SD), on performance, nutrient retention, carcass traits, gut conditions and cost per kg live weight gain. Results:The body weight gain in broiler chicks fed with BD supplemented with NSP enzymes, synbiotics and phytase was significantly (P<0.01) higher. Supplementation of NSP enzymes, synbiotics and phytase alone or in combination had significant effect on feed intake. Synergistic effect of NSP enzyme, synbiotics and phytase was observed on overall feed conversion ratio (1.86), which improved (P<0.05) in comparison to BD (2.06) and SD (2.02), respectively. The supplementation of NSP enzymes, synbiotics and phytase to BD improved (P<0.05) utilization of organic matter (OM), crude protein (CP), nitrogen free extract (NFE), gross energy (GE), phosphorus and the tibia ash compared to BD, whereas no effect on retention of DM and CF was observed. Intestinal viscosity and E. coli count significantly (P<0.01) reduced with addition of NSP enzymes, synbiotics plus phytase or combination of all. The supplementation of NSP enzymes, synbiotics plus phytase had no effect on intestinal histology. The cost of feeding was lower (P<0.01) in BD. Addition of these feed additives to BD did not increase the feeding cost and was comparable to unsupplemented ones and lower (P<0.01) than SD. Similarly, the feed cost per kg live weight gain during various phases of broiler production was reduced (P<0.01) due to supplementation of all the feed additives compared to SD and BD. Conclusions:It can be concluded from the above experiment that supplementing sub-optimal energy diets with NSP enzymes along with synbiotics and phytase improved body weight gain, FCR, nutrient retention, tibia ash and reduced the cost of production considerably.

The effects of a Bacillus licheniformis and phytase mixture added to broiler diets on growth performance, nutrient digestibility, and cecal microecosystem

“…Nevertheless, only an interaction trend (P=0.069) between the experimental factors that improved the CP AID coefficient was observed. These results are in line with the usage of synbiotic preparation and phytase combination to reduce the FI and FCR of broilers with simultaneous improvement in organic matter and nitrogen retention, as well as energy availability (Narasimha et al, 2013). Moreover, the mixture of prebiotic and phytase improved the BWG and FCR values in contrast to treatments in which the exogenous enzyme was used as a separate factor (Karimian and Rezaeipour, 2020).…”

Effect of dietary supplementation of prebiotic, probiotic, and synbiotic on growth performance and carcass characteristics of broiler chickens

“…The present findings were higher than the report of Narasimha et al . [ 30 ] who reported dressing yield (%) ranging from 63.67% to 66.67% in Cobb commercial broiler at 42 days of age. The carcass yield (%) in the present study ranged from 73.77% to 76.04% after 42 days of age which was more than the value observed by Abdel-Raheemand Abd-Allah [ 31 ] who reported 64.45 to 70.68% in Avian -48 broilers of 42 days of age.…”

Effects of Probiotics as Antibiotics Substitutes on Growth Performance, Serum Biochemical Parameters, Intestinal Morphology, and Barrier Function of Broilers

“…However, Sohail et al [28] found that PB had no effect on stress-induced injury in the intestinal morphology of 42-day-old chickens, which might be due to the variation of types and amounts of PB used in different studies. Moreover, the improvement of intestinal morphology and integrated intestinal barrier are important for epithelial cell function, which might be the reason for the improved ATTD of nutrients [29].…”
