Vitamins C and E affect plasma metabolites and production performance of layer chickens (<i>Gallus gallus domesticus</i>) under condition of high ambient temperature and humidity

Abstract

Abstract. This study was carried out to investigate the effects of vitamins C and E on some plasma metabolites and production performance of layer chickens reared under hot tropical climate. 720 White Leghorn (L33) layer chickens and 39 weeks old were divided into four groups of 180 birds. One group was fed with basal diet (control) and treatment groups were fed with basal diet supplemented with 150 mg of vitamin C/kg of diet, 150 mg of vitamin E/kg of diet, while the last group was supplemented with 150 mg of vitamin C/kg of diet plus 150 mg of vitamin E/kg of diet. Separately or as a combination, supplemental vitamin C and E decreased plasma concentrations of cholesterol, glucose and creatine phosphokinase (P<0.001) compared to control. There were no significant (P>0.05) effects of supplemental vitamin C and E on plasma metabolites of alanine phosphatase and aspartate transaminase. The single supplementation of vitamin E and its combination with vitamin C considerably increased the plasma metabolite of protein (P<0.01). Egg/bird were significantly (P<0.05) higher in all treatment groups compared to control, but P value was highest in vitamin E treated group. The laying index showed a significant (P<0.05) increase in all treatment groups compared to control. Similarly, feed consumption and conversion were significantly (P<0.05) different in treatment groups compared to control. It is concluded that supplementation of vitamins C and E maintained the stability of some plasma metabolites concentration, thereby, sustained production performance and facilitated adaptation of chicken to stressful hot-humid condition.

Effects of supra-nutritional levels of vitamin E and vitamin C on growth performance and egg production traits of Japanese quails

“…However, similar results were also obtained by a combination of vitamin E at 800 mg/kg level and C at 1000 mg/kg level. In agreement with our findings, several studies have reported increased egg production when Japanese quails fed diets supplemented with vitamin E and/or C (Bardakcioglu et al 2005;Sahin et al 2006;Ajakaiye et al 2010;Caurez and Olo 2013;Abedi et al 2017). In the current study, although the dietary addition of vitamin E plus C raised the total weight of produced eggs, no treatment effect was observed on the average egg weight in disagreement with Ipek and Dikmen (2014).…”

“…Vitamin E and vitamin C play a major role as antioxidants in biological systems and act individually or synergistically such that vitamin E explicates its antioxidant function in lipid phases whereas vitamin C in aqueous compartments by reacting with peroxyl radicals and by restoring the antioxidant properties of vitamin E (Cotelle et al 2003). Studies on poultry have reported that dietary supplementation with vitamins E and C, alone or together, can improve growth performance (Sahin and Kucuk 2001;Ajakaiye et al 2010), egg production and egg quality (Ajakaiye et al 2011;Caurez and Olo 2013). Because the most of studies were conducted under heat stress condition, further research is necessary to study the effects of additional vitamin E and C in diet of quails reared under standard environmental condition.…”

Effect of different levels of alpha tocopherol on performance traits, serum antioxidant enzymes, and trace elements in Japanese quail ( Coturnix coturnix japonica ) under low ambient temperature

“…Its determination is indicative of oxidative stress in the liver tissue, since a high concentration of the enzymes is linked to the liver disease (Perić et al, 2010). In the study of Ajakaiye et al (2010) and Jiang et al (2013), the level of AST and ALT did not differ between the control and the vitamin E treated birds up to the levels of 150 mg/kg and 200 mg/kg, respectively, which may be due to the difference in experimental protocol, dose, and duration of vitamin E. Similar results were reported by Perić et al (2010) when broiler chicks were supplemented with 0.3 ppm selenium. In this study, reduced concentration of liver enzymes may be due to the antioxidative effect of vitamin E.…”

Efficacy of Overdosing of Vitamin C Suppementation on Growth Performance, Europe Production Efficiency Factor (Epef), Carcass Traits and Some Blood Constituents of Japanese Quail

“…The authors concluded that there was a beneficial effect of vitamin C supplementation in the diet of broilers on body weight, of broilers. Studies on poultry have reported that dietary supplementation with vitamins C, alone, can improve growth performance (Sahin and Kucuk 2001;Ajakaiye et al 2010) On the other hand, results of Ipek et al( 2007) mentioned that the highest body weight was demonstrated in quail on 500 mg of Vitamin C/kg feed and Durrani et al (2008) found when giving Aloe extract 10 ml/liter to broilers in drinking water resulted in better body weight. Vathana et al (2002) reported that during the first three weeks, no difference in body weight among different treatments was detected (p>0.05).…”

“…Vitamin C with other vitamins such as vitamin E play a major role as antioxidants in biological systems and act individually or synergistically such that vitamin E explicates its antioxidant function in lipid phases whereas vitamin C in aqueous compartments by reacting with peroxyl radicals and by restoring the antioxidant properties of vitamin E (Cotelle et al, 2003). Studies on poultry have reported that dietary supplementation with vitamin C, alone can improve growth performance (Sahin and Kucuk 2001;Ajakaiye et al 2010). Al-Ghamdi (2008) suggested that the alteration in plasma vitamin C level can be used as a heat stress indicator in broiler chickens.…”
