Anadara granosa shell powder improves the metabolism, testosterone level, and sound frequency of Pelung chickens

Background and Aim: Pelung chickens make unique, pleasant, and rhythmic sounds in addition to having strong muscle
mass. Performance is controlled by testosterone. A natural aromatase blocker is an agent capable of blocking the aromatase enzyme, which consequently prevents testosterone from being changed into estradiol. Such a condition results in consistently high testosterone levels. The aim of this study was to determine the effect of the administration of the shell powder of Anadara granosa on the testosterone level, frequency and quality of sounds, and metabolism of Pelung chickens within set parameters of thyroid hormone levels, the triiodothyronine (T3 )/thyroxine (T4
) ratio, and weight gain.

Materials and Methods: This study used four Pelung chickens aged 14 months. Control data consisted of data before
treatment (day 0). Shell powder of A. granosa was administered for 56 days. Body weight (BW) was measured, and blood samples were drawn. In addition, the sounds from Pelung chickens were recorded once every 2 weeks on days 14, 28, 42, and 56. The blood samples were analyzed using the enzyme immunoassay method to determine testosterone, T3
, and T4 levels. The sounds of Pelung chickens were recorded using the Hagemon touch method and analyzed using the Audacity application.

Results: The results showed a significant difference (p<0.05) in the levels of testosterone, BW, and sound frequency after the administration of A. granosa shell powder, but the administration did not have a significant effect on the levels of T4 and T3 hormones (thyroid hormone), T3 /T4 ratio, or sound duration. The testosterone content and BW of Pelung chickens increased from day 14 to day 56, whereas T3 was indicative of the same profile as the T4 hormone. However, T3 and T4 levels and the T3
/T4 ratio decreased and increased, respectively. The sound frequency of Pelung chickens increased from day 0 to
day 14, although sound duration decreased.

Conclusion: The administration of A. granosa shell powder at 0.9 mg/kg BW orally could improve the metabolism,
testosterone level, BW, and sound frequency of Pelung chickens
