“…Body weight gain in WSR extract supplemented groups (infected as well as noninfected) was significantly higher as compared with their respective control groups indicating an accelerated growth response in the WSR extract supplemented birds. The enhanced growth rate because of WSR supplementation might be attributed to improved feed conversation ratio and free radical scavenging effect of WSR supplementation ( Akotkar et al., 2007 , Vasanthakumar et al., 2015 ). The significant reduction in serum total protein concentration in all the infected groups was due to hypoalbuminemia.…”

The present study was undertaken to investigate the effect of aqueous Withania somnifera root ( WSR ) extract in broiler chicks experimentally infected with Escherichia coli O78 @ 10 7 CFU/0.5 ml intraperitoneally. Clinical signs and mortality due to colibacillosis observed in infected chicks were mild and lasted for short duration in WSR extract supplemented group as compared with the nonsupplemented group. A significant increase in serum alanine transaminase, aspartate transaminase, lactate dehydrogenase, and creatine phosphokinase activities and a decrease in total protein and albumin concentrations were observed in the infected groups, though these changes were of lower magnitude in WSR extract supplemented group. A significantly higher activity of oxidative blood parameters such as superoxide dismutase, catalase, glutathione reductase, and glutathione-S-transferase enzymes were noticed in WSR extract supplemented group. The WSR extract supplemented group revealed significantly higher E. coli– specific antibody titer and enhanced lymphocyte proliferation response as compared with the nonsupplemented group. The gross and histopathological lesions of colibacillosis were mild in the WSR extract–supplemented infected group as compared with the nonsupplemented infected group. Withania somnifera root extract supplementation produced 31.48 and 34.38% protection in the gross and histopathological lesions in E. coli infected chicks, respectively. It is concluded that supplementation of 20% WSR extract @ 20 ml/L of water caused a reduction in the severity, mortality, and recovery period of E. coli infection and enhanced the humoral and cellular immune responses suggesting its protective effect on limiting the pathology of E. coli infection in broiler chickens.

Nutritional enrichment of broiler breast meat through dietary supplementation of Indian ginseng Withania somnifera and synbiotic substances under semi-arid climatic conditions

Aim:The present study was conducted to explore the effect of supplementation of Withania somnifera and synbiotics alone or in combination on the composition of broiler breast meat under heat stress conditions.Materials and Methods:A 42-day feeding trial was conducted on 360 broiler chicks randomly allotted into eight treatment groups with three replicates each under completely randomized design. The T1 group was kept as control whereas T2-T4 were supplemented with 0.5%, 1%, and 1.5% W. somnifera root powder; T5 and T6 were supplemented with 0.025% and 0.050% synbiotic and T7 and T8 were fed on diet containing 0.25% W. somnifera+0.025% synbiotic and 0.50% W. somnifera+0.05% synbiotic, respectively. Three broilers from each replicate were sacrificed at the end of the trial to estimate crude protein (CP), ether extract and ash content of the breast muscle on dry matter basis.Results:Significantly higher CP values and lower ether extract values were observed in 1.5% W. somnifera supplemented group (T4) or in group supplemented with 0.50% W. somnifera and 0.05% synbiotic (T8). The ash content of breast meat was observed non-significant in T1-T4 groups however the inclusion of synbiotics in T5-T8 groups significantly raised the ash contents.Conclusion:The study concluded that inclusion of 0.5% W. somnifera with 0.05% synbiotic substance enriches the total protein content and reduces the total lipids content of broiler breast meat under heat stress conditions.

“…The use of herbal preparations can also be an effective method to boost the immune system. Early systematic studies identified a variety of herbal compounds as immunostimulants [79], with proven stimulatory effects on macrophages, T and B lymphocytes, and the modulation of cytokine secretion, immunoglobulin secretion, and class switching [29,[80][81][82].…”

“…Among them, phytochemicals and herbal immunomodulatory agents can occupy a centric position since they are cost-effective, with no or minimal side-effects, user-friendly and easily available, etc. [82]. Since heat stress can modulate the immune system towards anti-inflammatory and immune compromised status, immune-stimulatory supplements are of high impact in this condition, among which herbal preparations can have a significant place [598,599].…”

“…Aurantii Nobilis Pericarpium (Hesperidin) and Magnolia officinalis (Magnolol) are widely used in Chinese medicines for their antioxidant and immune stimulating properties which can be practiced in heat stress management [612,613]. Heat stress amelioration in broiler birds was evidenced by Ashwagandha root powder as well as extract supplementation by enhanced body weight, serum antioxidant concentration and improved immune status [82].…”
