Effect of adding L-carnitine and Protexin(R) probiotic on performance and some blood parameters of ostrich chickens

Abstract

This study was conducted to investigate the effects of adding L-carnitine and Protexin(R) probiotic on performance and some blood parameters of ostrich chickens. In this study, a total of 48 one-day old ostrich chicks randomly divided into four treatment groups. Each treatment comprised of 4 replicates and 3 animals in each replicate and reared for 8 week. The experiment was arranged in a completely randomized design. The dietary treatments were: Treatment 1 (Control): Basal diet without supplementation; Treatment 2: Protexin(R) probiotic with level of 1 kg/t; Treatment 3: L-carnitine 500 mg/kg diet; Treatment 4: Protexin(R) probiotic with level of 500 kg/t + L-carnitine 250 mg/kg diet. The results of this study indicated that diet supplementation with L-carnitine and Protexin(R) probiotic increased ostrich chickens weight and feed intake at 8 weeks of age in comparison to other treatment groups. The other results showed no significant differences in feed conversion ratio (FCR) among different treatments at 8 week of ages and Broilers receiving L-carnitine + Protexin(R) probiotic had lowest FCR compared to the other tratment groups. Furthermore, diet supplementation with L-carnitine and Protexin(R) probiotic increased blood glucose concentration of ostrich chickens at 8 weeks of age in comparison to other treatment groups. Futher result showed that birds received L-carnitine + Protexin(R) probiotic had lowest total cholesterol in compersion to other treatment groups and birds receiving L-carnitine and Protexin(R) probiotic had lower HDL, LDL, and VLDL concentrations in compersion control group. There were no significant effect in calcium and phosphorus concentrations between control and other treatment groups.

The effects of L-carnitine-loaded solid lipid nanoparticles on performance, antioxidant parameters, and expression of genes associated with cholesterol metabolism in laying hens

“…The administration of 100 mg/kg LC-SLNs decreased cholesterol in egg yolks by 25% and blood cholesterol by 16.49%, which is inconsistent with Rouhanipour et al results ( Rouhanipour et al, 2022 ). Supplementing with LC has been shown to decrease a variety of blood metabolites, including liver enzymes, cholesterol, and triglycerides, which the results of this study confirmed previous findings ( Parizadian et al, 2011 ; Awad et al, 2016 ; Fallah and Mirzaei, 2016 ). In contrast, Kazemi-Fard et al (2015) and Arslan (2006) conducted an experiment with various amounts of LC on laying hens and found that there was no significant change in plasma glucose, AST, ALT, TG, cholesterol, HDL, LDL, and VLDL concentrations across dietary regimens ( Arslan, 2006 ; Kazemi-Fard, et al, 2015 ).…”

“…According to reports, LC is a potent antioxidant that protects antioxidant enzymes from oxidative damage ( Canbolat et al, 2017 ). LC treatment can also decrease serum cholesterol and triglycerides in rats and domestic fowls ( Eskandari et al, 2004 ; Malaguarnera et al, 2009 ; Adabi et al, 2011 ; Jang et al, 2014 ; Fallah and Mirzaei, 2016 ; Rehman et al, 2017 ). The addition of LC to the laying hen diet reduced egg yolk cholesterol and triglycerides for unknown reasons ( Adabi et al, 2006 ; Rehman et al, 2017 ; Placidi et al, 2022 ).…”

Impact of Supplementing L-Carnitine on Productive and Reproductive Performance of Mamoura Chicken During the Winter Season

“…Several studies have confirmed the benefits of L-carnitine in the regulation of blood lipids, which include total cholesterol and triglycerides (Ardekani et al, 2012). The current findings are consistent with those of (Elgazzar et al, 2012), Fallah and Mirzaei (2016), who discovered that dietary fortified with L-carnitine resulted in a significant decrease in blood total cholesterol and AST and ALT when comparing with the control diet. Economic efficiency: Calculations were made using the prices of L-carnitine and fertile Mamoura hen's eggs and chicks as given in Table for the year 2021.…”
