“…The singing characteristic is inherited from their parents. A highly competing Pelung rooster is produced by the mating of a contest winner rooster with a female that had the closest bloodline to the male winner (Daryono et al 2021). The mating ratio of one male mating with more than one female is probably not common for Pelung chickens.…”

Abstract. Asmara IY, Garnida D, Indrijani H. 2022. Short Communication: The population number of Pelung chickens in West Java, Indonesia. Biodiversitas 23: 3373-3378. Domestic farm animals or, Animal Genetic Resources (AnGR), are part of the global biodiversity. The existence of AnGR, mainly local breeds, is threatened, and their population data is still far from complete. This study provides information about Pelung chickens (Gallus gallus domesticus), a local chicken breed in Indonesia. The purpose of this study was to offer an overview of the population, effective population size, and inbreeding rate of Pelung chickens in four regencies in West Java, Indonesia. The method used in this study was a survey of fanciers and breeders of Pelung. Interviews were conducted to reveal the production system and population data. The data were analyzed descriptively and then calculated to estimate the effective population size (Ne) as well as the rate of inbreeding (?F). This preliminary survey indicated that there was a change in the distribution of the Pelung chicken, in which Garut Regency has the largest population number of Pelung, with 5664 birds of all ages. In this study, Pelung chickens in different areas had high Ne (267-569), and the ?F can be considered fairly low (0.09-0.19). The results of the study are probably the first documentation of the population number of Pelung chickens in at least ten years. This research is the initial study that forms the basis for conducting a comprehensive survey on the Pelung chicken. This study offers an upper limit result of Ne, so that accurate diversity parameter such as using genomic information is required.

“…According to Arlina et al [18], sound production in chickens is caused by sexual dimorphism in the brain area. Control of singing in crowing is influenced by testosterone levels in the body [21]. Abinawanto et al [15] also stated that the transmitted crow structure is influenced by steroid hormones, especially testosterone and estradiol.…”

“…This specificity is then used to conduct a kinship analysis. Research on the use of this bioacoustics technique has been widely carried out by some previous studies [5]- [11], [20], [21] and has been applied in biological research on species diversity [26]. Therefore, this research will be very useful in conducting studies on indigenous local chicken species whose existence information needs to be known so that they can be appointed as one of the genetic resources which are one element of the biological wealth of a nation.…”

“…The scientific literature on this species has also never been written for publication, so this study has excellent novelty potential for research. [17] conducted research on bioacoustics analysis that correlated the morphometric analysis of local chickens on singer chickens, which included laughing chickens of dangdut and slow types, balenggek kokok chickens, pelung chickens, and bekisar chickens [15], [16], [18]- [21]. Similar to this, Zulistiana and Abinawanto [20] conducted a morphometric study that was connected with bioacoustics analysis to conduct diversity studies on laughing chickens.…”

This study aims to obtain data on the diversity of nisi chickens based on morphometric analysis of body weight and bioacoustics analysis of the crowing sound. The number of studies linking morphometric analysis with bioacoustics analysis is one of the reference sources used in this study. In the future, it is hoped that this research will be one of the knowledge contributions for further or similar research. The parameters used in the analysis are neck length for morphometric analysis and bioacoustics parameters using the number of crowing syllables, crowing duration, and wave frequency. The data generated from the morphometric analysis were then analyzed statistically for the average test using ANOVA, which was analyzed together with the data generated from the Cold Edit Pro software to conclude the resulting data. The parameters observed were the number of crowed syllables, crowing duration, wave frequency, and crowing frequency. The results showed that the duration of the crowing of the nisi chicken ranged from 1.922 seconds to -2.064 seconds, with an average duration of 1.9837 seconds. The morphometric analysis of neck length results showed that the average neck length of 30 chicken samples was 10.25 cm, with the shortest range being 10.0 cm and the longest being 10.8 cm. The sound analysis results for the wavelength frequency of the crowing of the nisi chicken ranged from 698.10 Hz -786.22 Hz with an average wavelength of 733.89 Hz. For the number of syllables produced from the crowing sound, uniform results are obtained in 7 syllables. The analysis results using ANOVA obtained an F count of 0.001447, smaller than F table 1.656383. This study concludes that the neck length morphometric analysis does not affect the bioacoustics analysis, so the diversity of nisi chickens analyzed shows uniformity.

“…Pelung cockerels are native to Cianjur, a district in West Java, Indonesia [1][2][3]. The animal has been settled under the 2918/kpts/OT.140/6/2011 decree issued by the Ministry of Agriculture as native Indonesian freerange chickens and is obliged to be protected and conserved [4].…”

Background and Aim: Pelung cockerels (Gallus gallus gallusGallus gallus gallus [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. The shell of blood clams (Anadara granosa Linnaeus, 1758), a saltwater bivalve is known to contain a natural aromatase blocker (NAB) capable of blocking the aromatase enzyme from converting testosterone to estradiol. This generates consistently high levels of testosterone. This study aimed to determine the effect of blood clam shell powder (BCSP) as an NAB on the growth, pectoralis muscle performance, and testes of pelung cockerels. Materials and Methods: The study design was a completely randomized design, with 16 pelung cockerels aged 40–56 weeks divided into four treatment groups: T0 (control); T1 (BCSP [A. granosa] 0.9 mg/kg BW); T2 (zinc sulfate [ZnSO4] 0.9 mg/kg BW); and T3 (testosterone 3 mg/day). The animals were acclimatized for 7 days and then given dietary treatments for 56 days. The measurement of the comb, wattle, and chest circumference (CC) of pelung cockerels was performed on days 0, 14, 28, 42, and 56. At the end of the treatment, the pelung cockerels were sacrificed and the data of the pectoralis muscle weight (PMW), testis weight (TW), and area of the pectoralis muscle (APM) were measured. Samples of pectoralis muscle and testes were taken and fixed in 10% neutral buffer formalin for histology. The proliferating cell nuclear antigen (PCNA) was identified by immunohistochemical staining. To measure fascicle area (FA), myofiber area (MA), and enumerate, the fascicle myofibers (NM) histology preparations were stained with hematoxylin and eosin (H and E). Testicular preparations were stained with H and E to measure the diameter of the seminiferous tubules (DST) using ImageJ software. Results: The growth performance on day 56 showed significantly (p < 0.05) higher differences of CC in T1 compared to T2 and T0, in T1 and T3 compared to T0, and in T3 and T2 compared to T0. Pectoralis muscle results, that is, FA, NM, MA, and PCNA-positive cells, showed that cockerels on treatment T3 had significantly higher results than other treatments, T1 was significantly different from T2 and T0, and T2 was significantly different from T0. In addition, the TW and DST measurement of cockerels on treatment T3 were significantly reduced (p < 0.05) than the other treatment groups. Conclusion: The oral administration of BCSP in the role of a NAB at a dose of 0.9 mg/kg BW for 56 days improved the growth performance and pectoralis muscle, especially the CC, FA, NM, MA, and PCNA-positive cells parameters, but did not affect the PMW, APM, and testis of pelung cockerels. The administration of testosterone at 3 mg/day for 56 days contributed to the decrease in TW and DST, as well as atrophy of the seminiferous tubules of pelung cockerels. Keywords: growth performance, muscle, natural aromatase blocker, pelung, testis.
