| Abstract | ||
| The aim of this study was to evaluate the body weight and biometric characteristics of progenies produced by crossbreeding male Birjandi Cashmere and female Qom indigenous goats. For this purpose, a total of 38 goats indigenous and crossbred aged 1 to 4 years were selected. Body weights and biometric characteristics (neck and chest circumference, rump circumference, height at withers and body length) of goats were recorded. The data by genetic groups (including indigenous, crossbreds by first and second generation), gender and age were analyzed with SAS software. Results indicated that indigenous goats had higher (34.5±1.4 kg) body weight than F1 (31.0±0.9 kg) and F2 (28.9±1.8) crossbreds. The average of body weight and all of biometric characteristics of males were higher than females and with increasing age live weight of goats increased. Effect of genetic group except for neck and chest circumference, effect of sex except for body length and effect of age except for chest, rump circumference and body length for indigenous and crossbred goats were significant. Body weight of crossbred goats (Birjandi cashmere and Qom indigenous goats) significantly decreased in the first and second generation. The most biometric characteristics of crossbreds in the second generation were reduced | ||
