“…While the trachea of domestic fowl is not inserted into the sternum, it is considered that the thoracic bones such as clavicle, coracoid, and anterior part of the sternum restrict the space for vocal organs. Totenko is valued for its long, low crowing (Kuwayama et al, 1996;Akishinonomiya and Komiya, 2009). To generate this attractive sound, Totenko has a large anterior air sac and long trachea.…”

This study aims to understand the relationships among morphological characteristics, their functional roles, and breeder preferences in Japanese native fowls. We analyzed and compared the shapes and sizes of the skeletal forelimb, pectoral girdle, and sternum among six breeds: Chabo, Oh-Shamo, Onagadori, Shokoku, Tosajidori, and Totenko. Because skeletal forelimb, pectoral girdle, and sternum are one of the bases for composing body appearance and for movement of birds such as flapping, we treated those skeletons. All measurements of size were smaller in Chabo than those in other breeds except Tosajidori. The largest measurement values of all parameters were observed in Oh-Shamo. The largest measurement values were observed in all measurements of Oh-Shamo. Short and wide forelimb bones and a short coracoid were observed in Chabo. Oh-Shamo was equipped with a wide sternum and a widely articulated coracoid. Shokoku and Totenko possessed longer bones that constitute the thoracic cavity. We suggest that the small bone size in ornamental fowls contributes toward a cute appearance and that the large bone size of fighting fowls is correlated with their masculinity and aggressiveness. The short forelimb bones, wide articulation, and corpus of forelimb bones in Chabo create a round and soft body silhouette. The observed short coracoid prevents Chabo from dragging its body on the ground while walking. The wide sternum and articulation of the coracoid observed in Oh-Shamo are considered to contribute to the ability to pounce on an opponent by flapping during a fight. The wide sternum of Oh-Shamo is considered to affect its body outline, producing a strong, masculine physical appearance. We also suggest that the characteristics observed in Shokoku and Totenko create a space for the vocal organs, such as clavicle air sacs. We suggest that the observed morphological characteristics underlie the function and breeder preferences of each breed.

“…Some studies showed that genetics is an important element for crowing duration. Different breeds of chickens produced different crowing duration (Kuwayama et al 1996). In Japanese long crowing chickens, genes control crowing traits (Komiyama et al 2014).…”

Abstract. Asmara IY, Garnida D, Partasasmita R. 2020. Crowing characteristics of Pelung chickens at different age and body weight. Biodiversitas 21: 4339-4344. Crowing characteristics such as duration, frequency, and intensity are important factors to consider in determining a good Pelung. Age and body weight are among other factors being assumed to affect crowing characteristics. The study was conducted to determine the crowing characteristics of different age and body weight. A survey was carried out in Bandung, Cianjur, and Sukabumi Districts, West Java Province, Indonesia in which a total of 98 birds was selected using a purposive technique. The observed parameters were the duration, frequency, and intensity of crowing. The duration was the length of crowing measured by seconds. Frequency is several crowing in a particular time measured by times. Intensity is the magnitude of crowing measured by decibel. The crowing was recorded from 7 AM-2 PM. Data were analyzed using descriptive analysis and Mann-Whitney U Test to compare data differences between research areas. The study found that the crowing duration of Pelung roosters tends to increase in older birds, but the decrease in heavier birds. Crowing frequency increase along with age and body weight. Crowing intensity is similar in different age groups, while the intensity tends to decrease in the heavier group. The results provide evidence that age and body weight of chickens are an important aspect in Pelung contest and age should be considered as a new category in Pelung contest.

“… Kuwayama et al (1996) studied the duration and the pitch of crowing and reported that Totenko, Shokoku, Onagadori and Oh-Shamo produce a low voice. In this study, we noticed that Totenko, Shokoku, Onagadori and Oh-Shamo possess a larger mandible than Chabo and Tosajidori ( Tables 3 and 4 ).…”

“…The observed characteristics such as larger orbits and a circular-like silhouette in the present study are estimated to be the functional morphological characteristics for acquiring caregiving in ornament-type fowls. The Morphological Characters of the Bill and Orbit among the Oh-Shamo, Onagadori, Shokoku and Totenko Kuwayama et al (1996) studied the duration and the pitch of crowing and reported that Totenko, Shokoku, Onagadori and Oh-Shamo produce a low voice.

The skull of six Japanese fowl breeds, namely, Chabo, Oh-Shamo, Onagadori, Shokoku, Tosajidori, and Totenko, were morphologically compared in this study. The morphological differences in the skull size and shape among the breeds were as follows. 1) Oh-Shamo possessed a wide bill, thick bill tip, small orbits and wide mandibular joint. The characteristics of the bill and mandible were interpreted as functional characteristics to endure the shock of pecking. We suggest that the small orbits and a wide frontal bone help in protection from pecking in games. 2) Chabo possessed a small skull. In terms of shape, this breed possessed relatively large orbits, a wide and high skull and a short bill. The wide and high skull and the short bill formed a circular-shaped face. We propose that these characteristics have led to its characterisation as ornament-type fowl. 3) Totenko, Shokoku, Onagadori and OhShamo possess a long mandible. The long mandible led to an increase in the volume of the oral cavity. The wide resonance space is responsible for the low-frequency voice. The low-frequency crowing of Totenko, Shokoku, OhShamo and Onagadori is a result of the enlarged resonance space created by the long mandible. The orbits of Totenko and Onagadori were larger than those of Shokoku and Oh-Shamo. We suggest that Shokoku possessed the small orbits as a fighting cock. Since Onagadori and Totenko had been bred as ornament-type fowl, they possessed larger orbits.
