Effects of Probiotics and Phytoextracts on Growth and Immunomodulating Performances of Broiler Chickens

Abstract

An investigation was carried out to find out the effects of probiotics and phytoextracts (Korolla-bitter melon, Triphalatraditional three herbal components and Safi-commercial polyherbal products) on growth, hemato-biochemical (TEC, TLC, ESR, Hb concentration, PCV, ALT, AST, Cholesterol, Tryglyceride, HDL and LDL) and immunomodulating performance of broiler chickens. The study was performed from February to April, 2017. A total of 150, seven -days-old broiler chicks were divided into five (05) groups using 30 chicks in each group. The group A was designated as control group (without probiotics and phytoextracts), with probiotics (Exolution ® ) Group B, with phytoextract (Korolla-bitter melon) Group C, Triphalatraditional three herbal components Group D and Safi Group E. Chicks were reared for 35 days and body weight were measured on weekly basis. Broilers were sacrificed at the end of 35 days and blood samples were taken for hematological analysis. Serum samples were also taken for biochemical tests. Broilers in all treatment groups were necropsied at the end of the experiment to observe and determine the weight of the gross lymphoid organs (spleen, thymus and bursa of Fabricious). Both body weight gain, hematological parameters like TEC, TLC, Hb concentration and PCV values and size of lymphoid organs (spleen, thymus, Bursa of Fabricious) were increased in birds supplemented with probiotics and phytoextracts as compared with control group. In biochemical parameters, AST and ALT values were decreased significantly (p<0.05 and p<0.01) in groups B, C, D, E from that of the control group. The findings of the experiment would help us to assess the use of proper feed additives as healthy growth promoter and immunomodulator in broiler chickens.

Probiotics Improve Physiological Parameters and Meat Production in Broiler Chicks

“…There was non-significant difference in serum alanine aminotransferase concentration of broiler chicks in all groups up to 15 th and 30 th day of experiment. These results are in accordance to the results reported by Abdel-Fattah et al (2008), that supplementation of probiotics did not cause alterations in the ALT level, which proves that it is safer option for the liver, and it has been endorsed by Zuhra et al (2018). At the 42 nd day of experiment, there was a significant increase in serum alanine aminotransferase concentration of broiler chicks in infected groups B2, C2 and C2 compared to other groups and it is accordance to the results reported by Schimidt et al (2007), This change in ALT level can be attributed the tissue damage induced by the NDV in the birds.…”

“…From 6 th week of age, Hb concentration was significantly lower in infected groups B2, D2, and E as compared to control group A. Seyidoglu et al (2013) and Zuhra et al (2018) reported that Hb concentrations were increased by supplementation of yeast, phyto-substances and probiotics in feed.…”

“…At 5 th and 6 th week of age, total leukocyte count was significantly increased in NDV challenged groups (B2, C2, D2, and E) compared to Saccharomyces cerevisiae supplemented groups (B1, C1, D1, and control group A). Previously this TLC increase has been attributed to the yeast supplement in various species like rats, rabbits, and broiler (Liang et al 1998;Fleisher et al 2000;Seyidoglu et al 2013;Zuhra et al 2018). The increase is because yeast extracts have two different bioactive components: MOS and β-glucan.…”

“…From 6 th week of age, total erythrocyte count was significantly decreased in infected groups B2, C2, D2 and E as compared to probiotic supplemented groups B1, C1, and D1. Onifade et al (1999), Onifade (1997), Zuhra et al (2018) and Kumar et al (2021) reported that adding yeast Saccharomyces cerevisiae in the basal feed results in higher hemogram values, including total erythrocytes, leukocytes, and packed cell volume. There was a non-significant difference in total leukocyte count of broiler chicks in all groups upto 4 th week of age.…”

Effects of Dietary Momordica Charantia Supplementations on Broiler Performance, Blood Parameters, Meat Quality, and Intestinal Morphology

“…Shahadat et al [7] reported that, besides its anthelmintic effect, MC extract (30 g/liter drinking water) provides live weight gain in chickens infected with Ascaridia galli. Likewise, it has been reported that extract of MC improved the body weight of broiler chickens as feed additives, reduced liver function enzymes, and changed the lipid profile [12]. Nevertheless, comprehensive studies on the effect of MC on poultry performance are not enough.…”
