“…Testosterone is a vital male hormone. It controls voice, growth, muscle strength, spermatogenesis, and sex drive (Astuti et al 2006(Astuti et al , 2019Josiak et al 2014;Ko et al 2021;Yuneldi et al 2021aYuneldi et al , 2021bYuneldi et al , 2021cYuneldi et al , 2021d. Common practice of injecting anabolic hormones such as testosterone in male birds is proposed to maintain the performance.…”

Anadara clam shell contains high Zinc. This microelement is recognised as acting natural aromatase blocker (NAB) that capable of boosting testosterone level. The aim of this study was to evaluates the testosterone level of Canaries following Anadara nodifera administration. Adult male Canaries (n = 27) were group into 3 with 9 repetition of each i.e T0 [control, was given by Carboxymethyl Cellulose Sodium (Na-CMC)], T1 (Zinc Sulphate 0.013 mg/30 g BW), and T2 (NAB 0.3 mg/30 g BW). The T2 treatment was NAB or shell powder of Anadara nodifera which was diluted 1:1 in Na-CMC. The birds were treated orally for 21 days. The complete blood cell count was performed in a haemo analyser except the erythrocyte was calculated manually in the Improved Neubauer counting chamber. Testosterone level was measured in ELISA. Subsequently gen CYP19 aromatase in syrinx, brain and testis were identified employing IHC and descriptively analysed. The result indicated significant elevated level of testosterone (p<0.05). The expression of CYP19 aromatase receptor was depressed in syrinx, brain and testis. However there was no significant changes on the blood profile (p>0.05). To conclude, Anadara nodifera at 0.3 mg/30 g BW was capable of acting as NAB to promote testosterone level. This was confirmed by the reduction of CYP19 aromatase gene receptors in syrinx, brain and testis. However NAB treatment was not significantly affecting routine blood profile.

Background and Aim: Pelung chicken Gallus gallus gallus (Linnaeus, 1758) is a chicken endemic to Cianjur, West Java, Indonesia. This study aimed to determine the effects of zinc sulfate (ZnSO4) and synthetic testosterone supplementations for 56 days on testosterone hormone levels and breast muscle performance in Pelung chickens. Materials and Methods: This study used 12 Pelung chickens with three treatment groups (G) and four replications, namely, control (G0), ZnSO4 0.9 mg/kg (G1), and synthetic testosterone 3 mg/day (G2). Chickens were acclimatized for 7 days and then supplemented for 56 days. Drinking water and commercial standard feed were provided ad libitum. Blood was collected through the brachial vein for the analysis of testosterone levels using the enzyme-linked immunosorbent assay. The samples were collected every 14 days; on days 0, 14, 28, 42, and 56. Breast muscles were collected for texture analysis, and breast muscle preparations were made with hematoxylin-eosin staining to measure the fascicle area (FA), number of myofibers in one fascicle (NMOF), and myofiber area (MA). The collected data were analyzed using analysis of variance at a 95% confidence level with the help of Statistical Package for the Social Sciences v.29.0. Furthermore, principal component analysis (PCA) was performed with the help of Minitab v. 19. Results: Statistical analysis results on 56 days of testosterone level parameters showed that G2 was significantly different from all treatments (p < 0.05). The results of statistical analysis on Pelung chicken breast muscle performance, especially hardness, chewiness, FA, NMOF, and MA, were significantly different (p < 0.05) compared with the other treatments. The results of PCA showed that the testosterone level parameters were positively correlated with FA, NMOF, MA, hardness, and chewiness, whereas the fracture parameters were negatively correlated with all parameters except the springiness index and were significantly different between the G2 group and the other groups (p < 0.05). Conclusion: It can be concluded that supplementing synthetic testosterone 3 mg/day body weight for 56 days can improve testosterone levels and breast muscle performance, especially hardness, chewiness, FA, NMOF, and MA in Pelung chickens. Keywords: muscle, Pelung chicken, performance, testosterone, texture.
