“…As consequence, there is a growing interest in investigating alternatives to antibiotics feed additive in animal feed industry. Among the potential antibiotic substitutes, essential oils (Dieumou et al, 2009;Krishan and Narang, 2014), probiotic and prebiotic (Tuohy et al, 2005) and metals ions such as gold (Wei et al, 2007) and silver (Dongwei et al, 2009) can be listed. Silver ion (Ag + ) is a compound having multiple biological actions.…”

Objective: This study was conducted to investigate the chelating effect of silver nitrate (AgNO3) by chitosan on growth performances, hematological and biochemical parameters, and the histopathological structure of the liver and the kidney in broiler chicken. Materials and methods: A total of 192 day-old Cobb 500 strain chicks were randomly assigned to 3 treatments of 64 chicks each. Control group was fed on basal diet without supplement (R0) and the two others groups were fed on rations supplemented with 10 mg of unchelated (RAg) or chelated (RCs-Ag) AgNO3 per Kg of feed, respectively. Parameters that have been studied consisted of feed intake, weight gain, blood and serum biochemical, and histopathological analyses of liver and kidney. Results: Results revealed that chelation of AgNO3 by chitosan did not have any effect on growth performances and hematological parameters in chicken. However, chelated and unchelated AgNO3 increased the serum content in triglyceride, and cholesterol and decreased the serum content in creatinin, albumin and alanine aminotransferase (ALAT). Chelating AgNO3 with chitosan prevented and corrected the toxicity induced on the histological structure of liver and kidney. Conclusion: Chitosan can be used as a chelating agent to alleviate the harmful effects of AgNO3 as silver ion for poultry.

“…Essential oil (EO) is the mixture of volatile aromatic components from plants, such as herbs, spices and trees, and their major components are known as terpenes and phenylpropenes (Krishan & Narang, 2014). According to previous studies, EOs have multiple biological properties including antimicrobial (Nazzaro, Fratianni, De Martino, Coppola, & De Feo, 2013), antioxidant (Fernandez-Panchon, Villano, Troncoso, & Garcia-Parrilla, 2008) and anti-inflammatory (Craig, 2001) effects, providing the potential for EOs as an alternative for antibiotics in poultry diets.…”

This study was conducted to evaluate the effects of dietary phytoncides extracted from discarded Korean pine cones (Pinus koraiensis) on the performance, egg quality, immune response and gut microflora in laying hens. A total of 400 Hy-Line brown laying hens (50-week old) were allotted into four dietary treatments including a control diet or a diet supplemented with phytoncides at 0.002%, 0.004% and 0.008%. During the 6 weeks of experimental feeding, 0.008% of dietary phytoncides improved egg production, feed conversion ratio (p < 0.05), but not feed intake, egg weight or feed efficiency. Although dietary phytoncides had no effect on egg quality, decreases in Haugh units depending on storage periods were improved by 0.008% of dietary phytoncides (p < 0.05). To investigate the roles of dietary phytoncides on the alteration of the immune response during inflammation, lipopolysaccharide (LPS) or saline was intraperitoneally injected into 10 hens per diet group on the end date of the experimental feeding period. Serum immunoglobulins and splenic cytokine expression at mRNA levels were then measured at 4 hr postinjection. Although the levels of IgA were decreased by LPS injection in all dietary groups, dietary phytoncides at 0.008% showed a higher level of IgA by LPS (p < 0.05). Interestingly, although LPS injection resulted in an enhanced expression of proinflammatory cytokines such as IL-1β and IL-6, dietary phytoncides at 0.008% showed less increased levels of them (p < 0.05). Gut microflora was examined from 10 hens per diet group at the end of the experimental period. While the number of Lactobacillus spp. was increased (p < 0.05), Escherichia coli counts in the cecal contents were decreased by 0.008% of dietary phytoncides. Taken together, these results demonstrate that dietary supplementation of 0.008% phytoncides improved the egg production, immune responses during inflammation and gut microflora in laying hens.
