Context: Phenotypic characteristics of buck is a basic tools in animal husbandry due to selection criteria and economical profit. Objectives: The present research was conducted to evaluate the phenotypic traits of 60 bucks at Private Exotic Buck Breeding Centres in Rajshahi city with its adjacent area and Goat improvement Farm, Rajabarihat, Rajshahi, Bangladesh. Material and Methods: The experiment was conducted at private and government buck breeding centres of Rajshahi, Bangladesh during January, 2009 to October, 2010 to evaluate the phenotypic traits of 60 bucks, namely Jamunapari (n=9), Sirohi (n=15), Beetal (n=13), Crossbred (n=13) and Black Bengal (n=10) in relation to genotype and age. The data collected from the owners using pre-tested questionnaires analyzed with variance (ANOVA) and DMRT test. Results: The average value of phenotypic traits of buck as body weight, height at wither, height at rump, body length, heart girth, age at puberty, scrotal circumference, testicular length, scrotal diameter, paired testicular volume, libido (scale:1-4), servicing performance (scale:1-3), time required servicing, ejaculate time, services per day (times), conception rate (CR) and non return rate(NRR) at 60 days were 48.41±2.0 kg, 86.13±1.7 cm, 86.57±2.7cm, 108.1±2.1cm, 84.81±1.2 cm, 6.35±0.20 month, 26.12±0.42 cm, 14.73±0.28 cm, 8.30±0.13, 415.5± 19.38 gm, 3.51±0.60, 2.65± 0.21, 2.53±0.14 minutes, 10.88±0.57 seconds, 2.36±0.27, 82.25±1.5% and 86.53± 0.81%, respectively. Genotype had significant effect (P<0.05) on all the phenotypic traits of buck except on libido and servicing performance. The overall phenotypic performance was better in >2 years aged group of buck. Conclusion: The Private exotic buck breeding centre plays a vital role for improving of Black Bengal goat as well as Beetal, Sirohi and Jammunapari cross-bred goat that are suitable genotypes for meat and milk production in Rajshahi of Bangladesh.
