Abstract

Cross breeding is the process of improving the genetic quality of a goat herd, facilitated by utilizing superior breeds. The aim of this breeding method is to enhance desirable traits such as increase meat production, higher milk yield. In this study, female animals identified as 50%Anglo- nubian (AN)-50%Native goat (Nat) served as the maternal line. A purebred Boer(B) was utilized for the production until third generation to produce F3- 87B- 6.5AN-6.5N, which is considered as the terminal cross. Production data such as body weight at birth weight, weaning weight (weight at 90 days old), market weight (slaughter weight), type of birth, external body measurements (wither’s height, rump height, body length, flank girth at market weight) for analysis to established data for animal characterization and basis for selecting best cross breeds for meat production. The activity was participated by 32 farms utilizing data of 556 heads of animals. The production performance, F3 Boer crossbred, particularly male group reached birth weight of 2.9± 0.41 kg, weaning weight of 16.77 ± 1.24 kg and slaughter weight 29.75 ± 1.34. The external body measurement reveals that the height can reached 31.75 ± 1.58 in, the flank girth is recorded at 34.25 ± 2.57 in, and rump height can reached 34.25 ± 2.57 in. Therefore, the presence of these data can served as strong evidence to promote F3 Boer cross breeds to increase the production of chevon, in particular, male animals are recommended for slaughtering.
