“…In this study, VH and VH:CD improved in all segments of the small intestine in both the microencapsulated IgY and antibiotic groups. Previous studies have demonstrated that IgY and antibiotic addition to the diets can improve the development of broiler intestinal villi [ 24 , 35 ]. Moreover, the significant effect of microencapsulated IgY over non-microencapsulated IgY in this experiment may be due to the denaturation of non-microencapsulated IgY in the acidic environment of the stomach and its degradation by protein hydrolases present in the stomach and small intestine [ 14 ], leading to the increased digestibility of IgY.…”

Objective: Egg yolk immunoglobulin (IgY) is an antibiotic alternative to prevent and fight intestinal pathogenic infections. This study aimed to investigate the effects of sodium alginate/chitosan/sodium alginate IgY microcapsules on the growth performance, serum parameters, and intestinal health of broiler chickens.Methods: One-day-old broilers (Ross 308) were divided into five treatments, each with 10 replicates of five chickens. The dietary treatments were maintained for 28 days and consisted of a basal diet (NC), basal diet + 500mg chlortetracycline/kg diet (CH), basal diet + 50mg non-microencapsulated IgY/kg diet (NM), basal diet + 600mg low levels microencapsulated IgY/kg diet (LM), and basal diet + 700 mg high levels microencapsulated IgY/kg diet (HM).Results: Throughout the 28-day trial period, the NM, LM, HM and CH groups increased average daily gain (ADG) compared with the NC group (P < 0.05), and the HM group reduced feed conversion ratio (FCR) compared with the CH group (P < 0.05). The LM and HM groups increased relative organ weights of thymus and spleen compared with the CH and NM groups (P < 0.05). The HM group improved the duodenal, jejunal and ileum villi height (VH) and villus height to crypt depth ratio (VH:CD) compared with the CH and NM groups (P < 0.05). Compared with the CH group, the HM group increased serum immunoglobulin (IgA), immunoglobulin G (IgG), superoxide dismutase (SOD), total antioxidant capacity (T-AOC) and glutathione peroxidase (GSH-Px) levels (P < 0.05), and decreased serum malondialdehyde (MDA) levels (P < 0.05). Compared with the NC group, the NM, LM, HM, and CH groups reduced colonic Escherichia coli (E. coli) and Salmonella A c c e p t e d A r t i c l e levels (P < 0.05). and the HM group promoted the levels of lactic acid bacteria and bifidobacteria compared with the CH group (P < 0.05). Conclusion:Microencapsulation could be considered as a way to improve the efficiency of IgY. The 700 mg high levels microencapsulated IgY/kg diet could potentially be used as an alternative to antibiotics to improve the immune performance and intestinal health, leading to better performance of broiler chickens.

“…In response to feeding 0.1% or 0.2% whole plant powder in feed, increased antibody titers against the New Castle virus (NDV) were discovered in 42-day-old broilers [82]. Birds receiving 1% Aloe vera gel in their drinking water exhibited better antibody titres against sheep red blood cells (SRBCs) and NDV, as well as a stronger reaction to a phytohemagglutinin-P (PHA-P) injection, as compared to a control group, according to research by Darabighane et al [112]. In broiler chicks (1 to 42 days of age), diets supplemented with 2% Aloe vera gel increased the cellular immunological response to PHA-P injections compared to a control group [84].…”

Aloe vera: A Sustainable Green Alternative to Exclude Antibiotics in Modern Poultry Production

Over the past 50 years, there has been a rapid increase in the need for poultry meat on a global scale to meet the rising demand from health, ecology, safety and equity. However, there has been a significant rise in recent years in both public demand and scientific interest for organic poultry farming, particularly when using medicinal herbs due to the rising concern of antibiotic resistance in end users. Ban on the use of antibiotics in the poultry industry has resulted in the demand of herbs as alternatives to antibiotics. Various research efforts have illustrated the nutritional value of Aloe vera in improving growth performance and immune status and acting as an antibacterial and anticoccidial agent in poultry. Aloe vera has been used as a supplement in the form of gel, alcoholic extract, powder, polysaccharide and aqueous extract. Aloe vera contains more than 200 nutrients, bioactive compounds, polysaccharides and saponins. In the current review, we have detailed the effect of Aloe vera as an alternative to antibiotics on growth performance, antimicrobial and antiparasitic activities and blood biochemical alternations in poultry.
