Efficiency of Phytogenic Feed Additives in Improving Broiler Performance, Intestinal Bacteria and Ileal Histomorphology.

Abstract

hotogenic feed additives (PFA) have been suggested to promote broiler performance as alternative for antibiotics, which have been banned from the feed. The current study aimed to evaluate the effect of dietary PFA (Biostrong ® 510) on performance of broiler chicks, ileal content of bacteria, intestinal histomorphology and blood characteristics under the environmental conditions of Saudi Arabia Kingdom. Four-hundred-day-old Ross broiler chicks were allocated to four treatment groups with five replicates of 20 birds each. For 35 days experimental period, the chicks were fed on four different experimental diets: 1) positive control diet containing 21.24% crude protein and 2850 Kcal ME; 2) positive control with 150 g/t Biostrong® 510 added to the diet; 3) negative control diet containing 20.49% crude protein and 2801 Kcal ME; 4) negative control with 150 g/t Biostrong 510®added to the diet. Dietary addition of Biostrong ® 510 significantly increased body weight gain and feed conversion compared to birds fed the two control diets at the second stage of growth (3-5 wk.). Photogenic feed additive supplementation significantly reduced ileal content of E. coli and increased Lactobacillus bacteria. Plasma total protein, albumin, globulin, cholesterol, or triglycerides were not affected by adding Biostrong ® 510 into the diet. There is no significant effect on relative weight of the liver, spleen, heart or bursa of Fabricius between the different treatments. The results revealed a significant increase in villi length associated with a reduction in crypt depth due to inclusion of PFA into broiler diets. The small intestine thickness significantly reduced due to inclusion of PFA into the diet. From the current study, we can conclude that PFA supplementation has a positive effect on increasing the number of beneficial bacteria and villi length which improves nutrient digestibility and broiler performance.

Comparative Efficacy of Selected Phytobiotics with Halquinol and Tetracycline on Gut Morphology, Ileal Digestibility, Cecal Microbiota Composition and Growth Performance in Broiler Chickens

“…A cellular turnover is an energy-utilising event; shallow crypts resulted in decreased cellular turnover, thus reduced energy utilisation which might be used in growth events of broiler chickens. These findings are endorsed by earlier reports that showed increased VH, and shallow crypts indicated enhanced growth performance of birds [14,25,71].…”

“…In conclusion, supplementation of phytobiotics positively modulated the gut health by increasing the beneficial microbes, such as Lactobacillus , and restricting the growth of pathogenic bacteria, including E. coli , Staphylococcus aureus , Salmonella , and Clostridium . Current results are supported by a variety of other studies that reported that phytobiotics supplementation in broiler chickens significantly reduced the pathogenic bacteria including E. coli , Salmonella and Clostridium and significantly increased the beneficial bacteria ( Lactobacillus) [ 9 , 14 , 24 , 71 ].…”

“…Murugesan et al [ 9 ] found that phytobiotics can increase VH, reduce inflammatory events, and enhance the absorption efficiency in broiler chickens. Soliman et al [ 71 ] and Oso et al [ 45 ] endorsed current study findings where supplementation of PFAs had significantly increase VH and decrease CD. As with the present study results, the positive influence of phytobiotics on gut morphology in broiler chickens was reported in several studies [ 14 , 17 , 24 ].…”

“…In the present experiment, the broiler chickens fed on diets Po8, Pb4, HAL and AGPs showed improved (p < 0.05) digestibility of crude protein (CP), dry matter (DM) (except for HAL), organic matter (OM), ether extract (EE), and ash compared to the NC group. The current study results added information to previous studies that showed a positive influence of phytobiotics to increase absorption and digestibility of nutrients in broiler chickens [16,18,71].…”

Evaluation of Non-Fermented and Fermented Chinese Chive Juice as an Alternative to Antibiotic Growth Promoters of Broilers

“…Many studies have reported the distribution of intestinal microbes in poultry after adding phytogenic feed additives. Recently, Soliman [ 86 ] reported that botanical substances such as extracts of plants, herbs, spices, or essential oils can improve feed utilization efficiency, gut microbiome patterns, and stimulate the immune response in poultry due to their antibacterial and antioxidant effects. Mohiti-Asli and Ghanaatparast-Rashti [ 83 ] reported that phytonutrients in feed can reduce the abundance of E .…”
