“…The result from this study indicated that there are two distinct peaks in male sexual behavior, which coincided with the estrus behaviors of the female deer. The result from this study further enhances the findings suggested in another study on sambar deer, which found that the frequency of sexual behavior in males can be used to estimate the presence of females in estrous in sambar deer (Putranto et al, 2010). The observed peaks in reproductive behavior on days 6 and 10 further highlight the temporal dynamics of sexual activity in male sambar deer.…”

Understanding the reproductive behaviors of different wildlife species is essential to unravel their reproductive strategies, ecological adaptations, and conservation requirements. This study delved into the reproductive biology of the sambar deer (Rusa unicolor), with a focus on promoting assisted reproductive technology for wildlife conservation and investigating the reproductive behaviors of male and female sambar deer. The study was conducted at Pusat Konservasi Hidupan Liar (PKHL) Sungkai, Perak, Malaysia. The observation focused on one male and two female sambar deer. Direct observations of the deer were conducted for 14 days in September 2022. The direct observations were performed in the morning (Session 1= 8-10 am), afternoon (Session 2 = 10-12 pm), and evening (Session 3= 3-5 pm), using the instantaneous sampling method. A total of 75 behavior instances were recorded, in which male deer exhibited the most reproductive behavior at 58 instances (77.3% of the total reproductive behavior). Successful mating was observed on day 6, elucidating a crepuscular preference in the male animal in exhibiting reproductive behavior. The female’s reproductive behavior lasted for a short period, from 24 hours for Female 2 and 72 hours for Female 1. In conclusion, there was a distinct behavior between the male and female deer during the rutting season. Understanding the reproductive behavior to estimate the length of estrus can be useful as a non-invasive tool to detect heat and can be considered to improve breeding management and implement assisted reproductive technology.

“…This probe more questions to the factors that could the trigger the seasonality in tropical deer as most studies specifically in deer seasonality suggested to investigate the possible linkage of breeding seasonality with meteorological data, especially rainfall (Asher, 2011;Asher et al, 2000;Umapathy et al, 2007). Our findings is in agreement with Sambar deer which has no significant effect of rainy or dry season based on reproductive cyclicity and sexual behaviors (Putranto et al, 2010). Other study in bats in the tropics suggested that while breeding seasonality can easily be understood in short-lived mammals, breeding seasonality of long-lived mammals such as deer is far more complex and multifactorial (O'Brien, 1993).…”

Breeding seasonality in mammals is influenced by the environmental changes and the endocrine response of the animals to that changes. Comprehension in breeding seasonality enables better reproductive management consequently maximizing the reproductive potential of the stags. Despite that, the study in breeding seasonality in Rusa deer (Rusa timorensis) is still scarce. Five healthy and matured stags were selected for this experiment. Semen were collected using electroejaculator at a monthly interval from April to September 2012. Semen motility is determined using a percentage. Meteorological data were obtained from the nearest weather station located in Petaling Jaya. Serum was utilized for the radioimmunoassay determination of serum testosterone profile. The warmest condition was in June and it's coolest in November of 2012. There was a strong, positive correlation between testosterone concentration and general motility (p<0.05) with a correlation coefficient, r s = 0.943. Meteorological data alone; temperature, relative humidity and rainfall are insufficient to determine the breeding seasonality in Rusa deer, bearing no significant correlation with serum testosterone concentration and sperm motility. Rusa deer stags is reproductively active from April to July, low in August and starts to rise again in September. Therefore, this study demonstrates that breeding seasonality in Rusa deer stags can be determined via serum testosterone profiling.

Indigenous chickens such as kedu, cemani, pelung, bekisar, merawang, balenggek and nunukan chicken are well known and famous as fancy fowls or landrace chickens among Indonesians.…”

Abstract. Putranto HD, Setianto J, Santoso U, Warnoto, Nurmeliasari, Zueni A. 2012. Estradiol-17β hormone concentration and follicles number in exotic Burgo chicken supplemented by Sauropus androgynus leaves extract. Biodiversitas 13: 1-6. Bengkulu Province of Indonesia has an indigenous crossbreed chicken named burgo or Rejang chicken. A conservation effort in this study was represented by supplementing 4 different levels of Sauropus androgynus or katuk leaves extract (KLE) to improve number of fertile eggs. The purpose of study was to identify the effects of KLE supplementation on female burgo chicken's serum estradiol-17β (E2) hormone concentration profile and number of follicles. KLE was added into drinking water (0, 9, 18 and 27 g/chicken/day) during 8 weeks of treatment. The results showed that supplementation of KLE dosed 9 to 27 g/chickens/day had significantly affected E2 concentrations and number of follicles (P < 0.05). In contrast, the average of female burgo E2 concentration with supplemented KLE was higher than control group. The total number of small follicle yield was highest (86.5%) compared to medium follicle (7.8%) and large follicle (5.3%). Many primary follicles (primordial) and post ovulatory follicles were probably in micro size and unseen by an usual visual counting. It seems that serum E2 hormone concentration correlated to total number of preheararchal follicles. Supplemented KLE was able to improve the serum estrogen steroid hormone concentration and number of preheararchal follicle (small and medium follicles) in female burgo chicken.
