Phenotypic and Morphometric characterization of indigenous chickens at Jhenaigati upazila of Sherpur district in Bangladesh

Abstract

The study was conducted at Rangtia, Shalchura and Dudhnoi villages under Jhenigati upazilla of Sherpur district in Bangladesh for phenotypic and morphometric characterization of indigenous chickens. Among three types of indigenous chickens, Non-descript Deshi were prominent (86%), compared to Cap Headed (10%) and Naked Neck (4%) and the overall mean body weight, back length, body circumference and pelvis width were 961.50 ± 17.79 gm, 152.70 ± 1.29 mm, 219.20 ± 1.89 mm and 25.57 ± .62 mm respectively. The prominent colors of plumage, shank, skin, earlobe and eggshell were multiple (24%), white (52%), white (89%), white & red (47%) and white (48%), respectively while 99% chicken's had single comb. The highest correlation (0.70) was observed between body weight & body circumference followed by (0.36) between body weight & back length and (0.27) between body weight & pelvis width while eggshell color was significantly correlated with body weight (-0.48), body circumference (-0.41) and pelvis width (-0.26). However, comb type was significantly (p<0.05) affected body weight and pelvis width. But bird type had significant (p<0.05) effect on pelvis width only. Present study reveals that variations in some phenotypic characteristics have significant influence on the pelvis width and body weight while a little change in some morphometric traits may affect body weight of indigenous chickens in Bangladesh which may serve as important indicator trait(s) for future research on the conservation and development of indigenous chicken ecotypes in-situ.

“…Further the results showed that availability of plans and usage of resources had no correlation with timeliness of activity delivery with r=0.024 and r=0.077 respectively. These results revealed that plans were not availed on time and resources were not timely used which could have influenced the performance of indigenous chicken projects.This result is in agreement with the study of Tabassum, et al, (2014) and Sathe (2012) where they indicated that lack of timely availability of resources influences performance of indigenous chicken projects.…”

“…This result revealed that the performance of indigenous chicken improved as most project implementers used brooders to brood their chicks and fed them with chick mash. Similarly on timely activity delivery, the project implementers agreed that they got the plan of activities early, formed groups which facilitatedearly trainings with a mean score of 3.7971 and acquired their chick brooders earlywith mean score of 3.7029 as asserted by Tabassum, et al, (2014) where they indicated that the resources should be timely acquired. This result revealed that the project management was delivered on time; the project implementers undertook the management practices on time hence improving performance of indigenous chicken.…”

“…Likewisea study by Siyaya and Masaku (2013) in Swaziland asserted that lack of resources and planningto cause poor performance in Indigenous Chicken projects during implementation. Further Tabassum, et al, (2014) in Bangladesh and Sathe (2012) identified that timely availability of resources to improve performance of indigenous chicken projects during implementation. Similarly Okeno, et al, (2012) results revealed poor planning and lack of breeding program to supply resources like quality breeding stock to cause poor performance of indigenous chicken during execution.…”

“…According to Alabi et al (2012), body weight was highly correlated with linear body measurements in Naked Neck and Venda chickens and it was non-significant (p> 0.01) in Koekoek chicken of South Africa. In another study, Tabassum et al (2014) also reported that the highest correlation (0.70) between body weight and body circumference, followed by correlation (0.36) between body weight and back length, and correlation (0.27) between body weight and pelvis width were observed. But there was no significant correlation between back length and body circumference, back length and pelvis width, and body circumference and pelvis width.…”

“…neck plumage color was strongly associated with back plumage color, while wing plumage color was associated with neck and back plumage colors. Whereas, Tabassum et al (2014) reported that bird and comb type, shank, eggshell, earlobe, skin and plumage color had no significant correlation between each other. So bird type, plumage color, shank color or eggshell color did not affect each other significantly of indigenous chickens at Jhenigati Upazilla of Sherpur district in Bangladesh.…”
