This study aimed to assessthe effect of vitamin B complex to the shrinkage of body weight due to 7 hours transportation at a young and mature age of Kacang goats. The materials used were16 male Kacang goats at average body weight (BW) of13.04 ± 2.31 kg (CV = 17.6825) and vitamin B complex injection were used in this study. The experimental design used was a completely randomized design nested design for 2 groups, 2 treatments and 4 replications. Experimental groups in this study were young group (BW of 11.14 ± 1.63 kg) and adult group (BW of 14.94 ± 0.71 kg) in which each group were treated without(T0) and with giving vitamin B complex (T1). Transportation was conducted from 9:00 to 16:00 at a distance of ± 300 km. Parameters observed include the initial BW and final BW to calculate BW shrinkage and fecal weight. The results showed that the shrinkage of BW at T0 and T1 goats at young age and mature were not significantly different (p> 0.05), as well as the weight of feces excreted. The conclusion of this study was vitamin B complex did not affect body weight shrinkage as a result of transportation at young and mature Kacang goats.
