Abstract
Boer are one of the goats with high growth potential and have good fertility. The expected advantage of the results of the crossing between Boer and Peranakan Ettawa (PE) goats is the effect of heterosis and breed complementary from its offspring which is characterized by good growth performance. The purpose of this study was to compare the offspring performance of Boer crossbred and Peranakan Ettawa in the same intensive production systems. The mating model used was a crossing model of Boer Fullblood buck as a source of genes mated with Peranakan Ettawa goat does which would be compared with the performance of native Peranakan Ettawa goats. This study was used 20 heads of goat divided into two experimental groups, namely crossing Boer groups (n = 10 heads), and Peranakan Ettawa goats (n = 10 heads). The measured performance parameters include birth weight, 1 month body weight and pre-weaning body weight. To see the difference between the two treatment groups, the data were analyzed using student t-test statistics. The birth weight of Boer cross goats has 4.25 ± 0.9 kg which was higher than Peranakan Ettawa goat (3.75 ± 0.5 kg), while the weight at 1 month age also shows a higher performance of Boer cross goats than Peranakan Ettawa goats (8.45 ± 1.9 vs 5.94 ± 0.8 kg) with the performance of average daily gain (ADG) which was also much higher (102.5 ± 93 vs 89 ± 26 g). Boer cross kids growth performance shows higher growth performance compared with Peranakan Ettawa kids. The Boer and Peranakan Ettawa goats crossing program produces a good heterosis effect to improve the performance of local goats, especially local goats that are maintained intensively in the Sulawesi region, Indonesia.
