“…Concerning liver and kidney functions, creatinine and total, direct and indirect bilirubin did not exhibit any significant changes among the groups. Similar to our results, Abdel-Wareth et al [35] showed that rabbits fed with nano-Se had a significantly lower urea level compared to the control group. Additionally, a significant reduction was reported in the TG level as a response to nano-Se supplementation in broiler chicks [38].…”

The adverse influences of elevated ambient temperatures during the summer season on the rabbit industry have received increased global attention. Therefore, this study intended to compare the potential effects of nano-selenium (nano-Se) synthesized by biological (BIO) and chemical (CH) methods on growth performance, carcass variables, serum metabolites, and inflammatory cytokines responses of growing rabbits in the summer season. Two hundred and fifty weaned rabbits (males, 35 days of age) were randomly divided into five treatment groups of 50 rabbits each (each group had five replicates with ten male rabbits). Treatment groups were fed a control diet and four controlled diets supplemented with nano-Se synthesized by biological method (BIO25 and BIO50, with a 25 and 50 mg of nano-Se/kg diet, respectively) and chemical method (CH25 and CH50, with a 25 and 50 mg of nano-Se/kg diet, respectively) for eight weeks. During 11 to 13 weeks of age, a gradual enhancement in live body weight (LBW), feed intake (FI) and feed conversion ratio (FCR) was noticed with BIO25 and BIO50 treatments compared to those in the other groups. The carcass percentage was significantly higher (p < 0.01) for animals fed with BIO25 than the other groups. The other organ functions were significantly higher (p < 0.01) in heat-stressed groups compared to that of nano-Se groups. Increasing the level of only BIO from a 25 to a 50 mg/kg diet gave more improvement in the studied parameters. Additionally, the concentrations of serum urea, triglycerides (TG), and glutamyl transferase (GGT) were lower (p < 0.01) in both treated and untreated groups. Likewise, the supplementation with nano-Se (BIO25, BIO50, or CH25) significantly improved the antioxidant indices and inflammatory cytokines responses as indicated from serum metabolites. Based on the study results, nano-Se especially synthesized by the biological method at diet levels of 25 or 50 mg/kg improved the growth performance, kidney and liver functions, carcass traits, antioxidants indices, and inflammatory cytokines of growing rabbits during thermal stress.

“…At the end of the experiment, fteen rabbits were used to collect blood samples from ear vein of in each treatment in non-heparinized sterile tubes. The samples were allowed to coagulate at room temperature for 30 min and then centrifuged at 3000 rpm for 15 min and the serum was harvested and stored at -20 C until used in the biochemical analysis as described previously by Abdel-Wareth et al [ 5]. Serum testosterone, aspartate transaminase (AST) and alanine transaminase (ALT), urea and creatinine were assessed conferring to the manufacturer's instructions by the spectrophotometric technique using commercial diagnostic kits (Monobind Inc.

Background Recently, restrict the use of antibiotic growth promoters by several countries and the menace of antibiotic resistant bacteria has forced to look for alternatives in rabbits. This study aimed to assess the efficiency of thyme essential oil (TEO) as a novel feed additive to dietary antibiotic to improve productive, reproductive performance and serum biochemical of male rabbit. Methods A total of one hundred and fifty 70-day-old male Californian rabbits were assigned to five dietary treatments including a basal diet as a negative control (NC), a basal diet was supplemented with an antibiotic as positive control (PC) and the basal diet was supplemented with 60, 120 or 180 mg/kg of TEO. The experiment period lasted for 60 days. Results Supplementation of TEO levels significantly (P < 0.01) increased body weight gain (BWG) and improved feed conversion ratio (FCR) of male Californian rabbits compared to NC and PC groups. Likewise, the TEO significantly improved semen characteristics of rabbits compared to NC and PC groups. Serum testosterone, aspartate transaminase (AST), alanine transaminase (ALT), urea and creatinine were improved by supplementations of thyme essential compared to NC and PC. Conclusions Based on the study results, TEO levels up to 180 mg/kg have the potential to improve productive and reproductive performances of Californian male rabbits.

Forty-eight weaned male New Zealand White rabbits aged 6 weeks with an initial body weight of (709.67 ± 13 g) were randomly divided into six experimental groups (8 rabbits each) for 6–14 weeks of age experimental periods. The present study was planned to evaluate the effect of using different forms of Selenium element (inorganic, nanoparticles and organic) as dietary supplementation on productive performance of rabbits. Six experimental groups in completely randomized design were used. The first group (G1, control) was fed the basal diet to cover maintenance and production allowances. Rabbits in the other groups G2, G3, G4 and G5 were fed the basal diet supplemented with Nano- Se at 0.02, 0.03, 0.04 and 0.05 mg/kg diet, respectively. The 6th group (G6) was fed the basal diet supplemented with 0.1 mg/kg diet of salinized yeast (Se-yeast) as organic form. The results indicated that the highest values of nitrogen free extract (NFE) and crude fiber (CF) digestibility, live body weight, daily weight gain, hot carcass weight and dressing percentage were observed with those supplemented with Nano-Se at all levels compared with other treatments. However, feed conversion, net revenue and economic efficiency values were improved with Nano-Se groups followed by organic Se group in comparisons with the control group. Conclusively, the Nano-Se in rabbit’s diet has a positive effect in improving rabbit’s performance and economic efficiency compared to the inorganic Selenium.
