Study on Testicular Biometric Parameters and Their Correlation in Non-Descript Breeds of Goat

Abstract

The study was conducted to compare the testicular morphometry parameters of right and left testis as well as their correlation in non-descript breed of goats. A total 16 mature testicles were collected from the Government approved slaughter house, in air-tight sterile cryobox (4-5°C) and brought to the laboratory within 2-4 hours after slaughtering the buck. The epididymis was carefully separated from each testis then testicular measurements were recorded. The mean epididymal length of right and left testes were observed as 12.01±1.33 cm and 12.36±1.44 cm; epididymal weight as 09.30±1.80 gm and 09.65±1.87 gm; testicular length as 05.91±0.91cm and 06.23±0.89 cm; testicular weight as 58.29±3.80 gm and 63.77±4.01 gm; testicular diameter as 04.19±0.59 cm and 04.44±0.69 cm; testicular volume as 54.38±4.39 ml and 62.50±4.46 ml and the testicular density as 01.11±0.41 gm/ml and 01.04±0.31 gm/ml, respectively. The correlation coefficient of various biometrical parameters of right and left testicles were significantly (p<0.01) positive correlated as: the epididymal length with epididymal weight; the testicular length with testicular weight; the testicular weight with testicular diameter; the testicular diameter with testicular volume (p<0.05) in right and (p<0.01) in left testicles but these testicular parameters were negatively correlated with testicular density in right and left testicles. It can be concluded that the non-significance (p>0.05) difference was observed between the right and left testes as regard to various testicular biometrics parameters.
