“…Lan et al showed that liver content decreased with age, while liver weight and abdominal fat weight increased in yellow-feathered broilers [23]. The testis content showed an increasing trend; this is similar to the results of Mfoundou et al [24]. However, the variation trend of abdominal fat traits was different from that of previous studies.…”

As an excellent chicken breed found in a high-altitude zone of northern China, Lindian chickens are characterized by good egg and meat production, strong adaptability, cold tolerance, rough feeding resistance, excellent egg quality, and delicious meat quality. To facilitate the exploitation of the unique qualities of the Lindian chicken, the varying patterns and correlations of various body size and carcass traits of 3–22-week-old Lindian chickens were analyzed in this study. The optimal growth model of these traits was determined by growth curve fitting analysis. The results showed that most traits of Lindian chickens increased steadily with increasing age, and most of them increased rapidly before 10 weeks of age. In addition, the inflection point age of each trait was predicted to be between 4 and 10 weeks. Furthermore, this study revealed that body size traits were closely related to carcass traits in Lindian chickens. In summary, Lindian chickens are in a rapid growth stage before the age of 10 weeks, and better slaughter performance can be achieved through good feeding management during this stage. The reproductive traits and muscles are the main developmental focus after the age of 19 weeks, so it is important to adequately meet their energy requirements for subsequent good breeding performance.

“…The seminiferous tubules are lined with germ cells that undergo a complex process of spermatogenesis to produce mature sperm. The interstitial tissue contains Leydig cells, which produce testosterone, a male sex hormone that plays a crucial role in the growth and development of broiler chickens, as reported by Mfoundou et al (2022). Histological investigation of the testes also showed no noticeable change in their histoarchitectures.…”

“…Research has shown that the size of the seminiferous tubules is positively correlated with sperm count and sperm quality, both of which are important factors in male fertility. Larger seminiferous tubules have been associated with higher sperm counts, as well as a greater proportion of morphologically normal and motile sperm (Fragaso et al, 2013;Metayer et al, 2019;Mfoundou et al, 2022).…”

Supplementation of Cv (clove) and Ts (tulsi) augments the growth rate and gut health of broilers. However, studies on their impact on the vital organs and male reproductive system remain scarce. Therefore, the current study aimed to investigate the impact of Cv and Ts supplementation on hematological profiles, as well as the heart, lungs, liver, kidney, and testes of broilers, both morphologically and biometrically. Sixty one-day-old broiler chicks, divided into four homogenous groups (control-T0 and three supplement groups-T1, T2, and T3), were fed 0.5% Cv and 2% Ts (T1), 1% Cv and 3% Ts (T2), and 1.5% Cv and 4% Ts (T3) with drinking water for 21 d. Organ samples were collected on d 14 and d 28 for macroscopic and microscopic (hematoxylin and eosin stain) investigation. Cv and Ts didn't affect the hematological profile, organ weight gain, and their general histoarchitectures. However, the histomorphometric investigation showed an increased (p<0.05) parabronchus surface area of the lungs, size of the renal glomeruli, the diameter of the proximal and distal convoluted tubules of the kidney in the T1 and T2 groups, and size of the seminiferous tubules of the testes in group T1. These findings suggest that unlike antibiotic or steroid growth promoters (GPs), Cv and Ts have beneficial impacts on the vital organs as well as on the male gonad of broilers from the morphologic and biometric perspectives.

Testes are male reproductive organs which are responsible for producing spermatozoa and steroid hormones. This study aims to determine the histology and histomorphometry structure of bali duck testes in the grower phase at the age of 12 weeks in one of the farms in Mengwi District, Badung Regency. The number of samples used in this research was 10 male bali ducks that were in good health. There are two examination methods carried out, namely the qualitative descriptive anatomical structure and histology examination method and the quantitative histomorphometry examination method of bali duck testicles which are analyzed using the One-Sample T-test with a confidence level of 95%. The results of this study show the anatomical structure of the bali duck testicles which are located in the abdominal cavity, between the kidneys and the lungs. The pair of testicles have the shape of a bean and are cream colored. The results of research on the histological structure of bali duck testes consist of seminiferous tubules, interstitial tissue, leydig cells, and tunica albuginea. The results of histomorphometry measurements of bali duck testes showed that the wall thickness of the seminiferous tubules was 23.6760 ± 1.4425 (µm), the number of seminiferous tubules was 421.1000 ± 56.1396 and the thickness of the tunica albuginea was 29.5000 ± 5.048 (µm). Considering the importance of knowledge about the structure of bali duck testicles, it is recommended for future researchers to examine the structure and histomorphometry of bali duck testicles at different ages in the growing phase.
