Testosterone hormone levels and breast muscle performance of Pelung chickens after zinc sulfate and synthetic testosterone supplementation.

Background And Aim: Pelung chicken (Linnaeus, 1758) is a chicken endemic to Cianjur, West Java, Indonesia. This study aimed to determine the effects of zinc sulfate (ZnSO) 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), ZnSO 0.

Growth, pectoralis muscle performance, and testis of pelung cockerels ( [Linnaeus, 1758]) supplemented with blood clam shell powder ( [Linnaeus, 1758]).

Background And Aim: Pelung cockerels ( [Linnaeus, 1758]) are different from other native cockerels in that they have a long and unique voice, in addition to their tall, large, and sturdy body with a relatively heavy body weight (BW). The sound quality of pelung cockerels is affected by the structure of the syrinx and their large and strong chest muscles. The performance of the chest muscles, and subsequently its voice, is influenced by the hormone testosterone.

Haematological profiles of Indonesian fat-tailed sheep under different physiological conditions.

The aim of this research was to evaluate the effect of sex, age, feed and physiological conditions on the haematological profiles of Indonesian fat-tailed sheep. A total of 32 healthy Indonesian fat-tailed sheep in different physiological states (i.e.

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.

Lab-Made Electronic Nose for Fast Detection of and .

The aim of this study is to determine the performance of a lab-made electronic nose (e-nose) composed of an array of metal oxide semiconductor (MOS) gas sensors in the detection and differentiation of () and () incubated in trypticsoy broth (TSB) media. Conventionally, the detection of and is often performed by enzyme link immunosorbent assay (ELISA) and polymerase chain reaction (PCR). These techniques require trained operators and expert, expensive reagents and specific containment.

Effect of shell as natural testosterone boosters in Sprague Dawley rats.

Aim: This study aimed to evaluate the effect of shell supplementation on the regulation of male reproduction in rats.

Materials And Methods: The zinc (Zn) level of shell from blood clam (), green mussel (), and conch shell () was analyzed. The highest Zn content shell was fed to male Sprague Dawley rats for 0, 9, 30, and 50 days at the dose of either 0.
