Phenotypic characteristics of Belgian Blue x Brahman Cross and Wagyu x Brahman Cross crossbred population

The aim of the study was to identify the phenotypic characteristics of Belgian Blue x Brahman Cross and Wagyu x Brahman Cross at PT. WMP,Central Java. The materials used were 9 F₁-B, 13 F₁-W, 6 F₂-B and 7 F₂-W. The data collected include the colour, ADG, BW, BL, WH, and HG at 90-days old. The results showed dominant blackin F₁-B, brown in male F2-B and dark brown at the female. The F1-W was black-brown, and F2-W colour was light brown, brown, and dark brown. The ADG F1-B was 0.70±0.15 kg, F2-W was 0.58± 0.06 kg, F₂-B was 0.64 ± 0.17 kg, and F₂-W was 0.60 ± 0.25 kg. The BW (kg), BL (cm), WH (cm) and HG (cm) at F₁-B was 95.10±12.07; 77.98±3.80; 85.32±2.85; and 101.93±4.51, F₁-W was 86.21±9.60;77.64±5.92; 88.25±2.43; and 101.97±3.09, F2-B was 88.22±4.50 kg, 87.29±13.45, 94.18±6.90, and 104.13±2.29, then F2-W was 90.91±27.70, 80.77±15.41, 86.36±7.80, and 99.92±11.88 cm, respectifly. There were significant effect of crossing on ADG, BL andHG at F1 and F2 (P>0.05). The conclusion BB Cross cattle have a dominant trait in body posture, especially in the first offspring, while Wagyu Cross cattle tend to be more assertive in the coat colour.
