“…The testicle is the main organ producing testosterone. There is a positive correlation between testosterone levels and testicular weights [11]. The results showed that the NAB 66 group obtained the heaviest testicle weight among others, 26.39±4.14 gram.…”

The aromatase enzyme is an enzyme that converts testosterone to estrogen. This means that by administering aromatase blockers, testosterone levels increase and estrogen levels decrease. The problem faced is how the spermatogenesis process occurs because estrogen is needed as well in the process. This study aimed to evaluate the histopathological features of the testes due to the administration of natural aromatase blockers (NAB). Fifteen male Bangkok chickens were divided into 5 groups, namely: control group (C); testosterone continues (Tc 0.4 mg/bird/day); natural aromatase blockers 33 (NAB 3.3 g/bird); natural aromatase blockers 66 (NAB 6.6 g/bird); zinc (Zn): 0.45 mg/kg body weight (BW). The oral treatment was given for 35 days. The results showed that NAB did not affect wattle growth, but significantly affected testicle weight (p-value < 0.05). The NAB 66 group had the heaviest testis weight, followed by zinc, continuous testosterone, NAB 33 group, and the control group. This results was confirmed by HE staining on the testes which showed the thickness of the thickest spermatogenic and spermatid cell layers in the NAB 66 group. It was concluded that giving NAB did not harm the spermatogenesis process.

“…It has been demonstrated that blue and green lights improved growth performance and immune system (Cao et al, 2008;Sultana et al, 2013). Astuti et al (2015) observed that body weights were increased under blue light treatment without adversely affecting stress indicators. Similarly, Fayoumi chickens maintained under blue light feel better welfare than exposed to yellow, red, green lights (Hesham et al, 2018).…”

The present study was conducted to investigate whether monochromatic light affects the production performance, egg quality and some plasma parameters of layers. In this study, white and green fluorescent lamps were used to illuminate Brown-Nick hens for 8 weeks. Light sources made uniform to a light intensity of 15 lx. Forty-seven-week-old layers were divided into 2 groups of similar mean weight comprising 16 birds each and housed in individual cages. A 16:8 hours light:dark photoperiod was employed. The layers were exposed to conventional ambient temperature and 50-60% relative humidity for 24h per day. Performance was evaluated by recording feed intake, egg weight and egg production on daily basis; egg quality and egg cholesterol level on weekly basis; and blood parameters on 56 th day of the experiment. The results indicated that green light application did not have any significant effect on feed intake, feed conversion ratio, egg production, total number of eggs, total egg weight, average egg weight, cholesterol level of egg yolk and egg quality of laying hens. However, green light application affected egg yolk color a * and b * values, but decreased serum albumin concentration. The results suggest that green light application may improve the yolk color of laying hens.
