Does Productivity Index of Boerawa Does and Etawa Grade Does Fed by Traditional and Rational Foodstuff

Abstract

Boerawa goat is crossbreed between Boer buck and Ettawa Grade does. This research was conducted to investigate: (a) interaction between goat breed and kind of foodstuff to does productivity index of Boerawa does and Etawa Grade does, (b) the effect of goat breed on does productivity index of Boerawa does and Etawa Grade does, (c) the effect of kind of foodstuff on does productivity index of Boerawa does and Etawa Grade does based on their kid weaning weight. This research was conducted with experimental method using 20 Boerawa does and 20 Etawa grade does having two-three times of kidding period. Ten Boerawa does and 10 Etawa grade does got rational foodstuff (60% forage and 40% concentrate), and 10 Boerawa does and 10 Etawa grade does got traditional foodstuff (100% forage). Factorial (2x2) of completely randomized design with ten replications was used in this study. The result showed that there was no interaction between goat breed and kind of foodstuff to does productivity index of Boerawa does and Etawa Grade does. The result indicated also that does productivity index (40,900 kg) of Boerawa does higher (P<0,01) than does productivity index (30,996 kg) of Etawa Grade does. The result indicated also that does productivity index (41,298 kg) of goat got rational foodstuff higher (P<0,01) than does productivity index (30,598 kg) of goat got traditional foodstuff. It could be concluded that Boerawa does were more productive than Etawa Grade does.
