“…Ono et al showed that the growth trend of tibia length is slow after 11 weeks of age [27]. However, Udoumoh et al found that after sexual maturity the weight and volume of the testis were significantly greater than before sexual maturity, indicating that the testicles were developing late [28]. This is consistent with the discovery in this study that the testis weight of Lindian chickens reached its maximum growth rate in the later stage, implying that Lindian chickens reached sexual maturity relatively late.…”

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.

“…In particular, the germinal epithelium in the seminiferous tubules is the testicular component directly related to spermatogenic activity (27). Therefore, germinal epithelial thickness is a useful parameter in evaluating sperm production (28). It decreases due to decreased cell division (29).…”

Objectives: Spermatogenesis, in which cell regeneration continues, can be affected by environmental, chemical, psychological factors or various diseases. There is conflicting information in the literature about the effect of isotretinoin, which is widely used in acne treatment, on testes and spermatogenesis. Therefore, we planned a rat study to evaluate the long-term efficacy of oral isotretinoin on testicular tissues and spermatogenesis. Materials and methods: The Group 1 (n = 6) 7.5 mg/kg/day and the Group 2 (n = 6) received isotretinoin at a dose of 30 mg/kg/day dissolved in sunflower oil, the Sham Group (n = 6) received only sunflower oil by gavage, and the control group (n = 6) received standard feed and water for four weeks. After the 4th week, all animals were fed with standard feed and water and followed for the next four weeks. At the end of the 8th week, all animals were sacrificed under deep anesthesia. Seminiferous tubule diameters, epithelial thickness, apoptotic index, sperm number and motility recorded. Results: Sperm count, motility, vitality, diameter of seminiferous tubule and germinal epithelium thickness were decreased and apoptotic index increased in the groups received isotretinoin. There was no significant difference between the groups in terms of testosterone levels. Conclusions: We consider that further comprehensive studies, including human clinical trials, should be conducted to examine the negative effects of isotretinoin on spermatogenesis in the long term especially when there is a need using isotretinoin in men for various reasons and to eliminate the contradictions in the literature in this regard.

“…The male reproductive tract has been investigated histologically, ultrastructurally and histochemically in several species including bull (Abdel-Raouf, 1960;Mohammed, 2005;Oni et al, 2021;Staub & Johnson, 2018), camel (Ali et al, 1978;Tingari et al, 1984), rat (Pogach et al, 1993, sheep (Pedrana et al, 2008), goat (Farooqui et al, 2011;Sharma et al, 2011), and domestic fowl (Tingari, 1972;Udoumoh et al, 2021). The goat in general received the least attention (Leal et al, 2018).…”

Goat population in the Sudan is estimated to be around 40 million heads. Nubian goats constitute about 60% of this goat population.They played an important economical role in the livelihood of a large sector of the population in the rural areas. Nubian goats are well reputed as one of the prominent breeds of dairy goats in the tropics (Devendra & McLeroy, 1982;Hassan & El-Derani, 1990;Sulieman & El Shafei, 1984). Nubian goats are the progenitors of the world famous Anglo-Nubian breed (Aboul-Naga et al., 2012;Williamson & Payne, 1978). Goats are used as a representative of large animals for certain experimental purposes like studies on reproduction as the reproductive tracts of the male goat, ram and bull are essentially similar (Goyal, 1985). Among these three species, male goats receive preference because, unlike rams, and bulls, are inexpensive and easier to handle for surgical manoeuvres
