The current experiment was designed to estimate the comparative efficacy of selected phytobiotics Persicaria odorata leaf meal (POLM) and Piper betle leaf meal (PBLM) with halquinol, and tetracycline in broiler chickens. The 150-day-old broiler chickens were randomly assigned to five dietary groups. The dietary supplementation groups were the basal diet (BD), which served as the negative control (NC), and BD + 0.2 g/kg tetracycline, which served as the positive control (PC); BD + 0.03 g/kg halquinol (HAL), BD + 8 g/kg POLM (Po8), and BD + 4 g/kg PBLM (Pb4) were the treatment groups. Growth performance, gut morphology, ileal digestibility, and cecal microbiota composition were measured. On day 21, the body weight gain (BWG) was enhanced (p < 0.05) in the broiler chickens fed on phytobiotics (Po8 and Pb4) relative to the NC group, however, on day 42 and in terms of overall growth performance, BWG was enhanced (p < 0.05 in diets (Po8, Pb4, HAL and PC) in comparison with the NC group. Conversely, feed conversion ratio (FCR) was recorded reduced (p < 0.05) in Pb4, Po8, HAL, and PC group in comparison with the NC group. Supplementation of phytobiotics (Po8 and Pb4), HAL and PC, positively improved the gut morphology compared to the NC group. Furthermore, the maximum (p < 0.05) villus height (VH) in duodenum and jejunum was observed in broilers fed on diet Pb4. Supplementation of phytobiotics, HAL and PC, improved (p < 0.05) the digestibility of dry matter (DM) (except for HAL), organic matter (OM), crude protein (CP), ether extract (EE), and ash compared to the NC group. Dietary supplementation of phytobiotics (Po8 and Pb4), HAL and PC, significantly reduced the E. coli, Salmonella, and Staphylococcus aureus (except for HAL) counts compared to the NC group. However, supplementation of Pb4 resulted in significantly decreased total anaerobic bacteria and Clostridium spp. counts compared to the NC group. In addition, supplementation of phytobiotics significantly increased the Lactobacillus count compared to HAL, PC, and NC groups. In conclusion, dietary supplementation of phytobiotics improved the gut morphology, positively modulated and maintained the dynamics of cecal microbiota with enhanced nutrient digestibility, thus, increased the growth performance. Based on current results, phytobiotics could be used as an alternative to AGPs for sustainable broiler chicken production.

Supplemental Effects

Abstract This study aimed to determine supplemental effects of phytase (VTR BIO-TECH, China) on bone parameters, jejunal mucosa-associated microbiota, intestinal morphology, nutrient digestibility, and growth performance of broiler chickens (Ross 308). Newly hatched broiler chickens (360, 44 ± 6 g BW) were randomly allotted in 6 treatments with 10 birds per cage based on CRD and fed for 27 d. Dietary treatments were the supplementation levels of phytase providing (0; 500; 1,000; 2,000; 4,000 FTU/kg feed) and 0.15% less Ca and 0.15% less P than the recommended requirements by ROSS 2019. Titanium dioxide (0.4%) was added to the diets as an indigestible marker to measure AID. On d 27, 3 birds were randomly selected from each cage and euthanized to collect jejunal mucosa and tissue to measure microbiota diversity and morphology, ileal digesta to measure AID, and left tibia to measure bone parameters. Data were analyzed using SAS. Phytase supplementation tended to increase overall ADG (P = 0.078; 39.7 to 42.2 g/d), whereas without affecting the overall ADFI and G:F. Phytase supplementation reduced (P &lt; 0.05) Pelomonas (10.01 to 2.64%) and tended to reduce Helicobacter (P = 0.085; 10.67 to 0.88%); Pseudomonas (P = 0.090; 2.02 to 0.31%); Sphingomonas (P = 0.071; 1.03 to 0.19%). Phytase supplementation increased (P &lt; 0.05) villus height (884 to 989 µm); the AID of CP (65.4 to 70.6%) and P (36.3 to 43.7%). Increasing phytase supplementation from 0 to 1,296 FTU/kg increased (P &lt; 0.05) breaking strength (184 to 213 N) and P content in the tibia (9.5 to 10.0%). In conclusion, phytase supplementation up to 4,000 FTU/kg feed showed benefits on intestinal health by reducing harmful bacteria in the jejunal mucosa, enhancing intestinal morphology and by increasing the AID of nutrients; and on the bone parameters by increasing the breaking strength and P content.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.
