Abstract

Experiment was carried out at Cho Moi district, Long Xuyen city, An Giang province. Fifteen male rabbits flocks at 5 weeks old were allocated in a completely randomized design with 5 treatments (5 verieties of rabbits), 3 replications and one male rabbits flock per experimental unit (individually housed rabbit). The experimental rabbits in all tretments were given a commercial concentrate, and local grasses such as para grass (Brachiaria mutica), water spinach (Ipomoea aquatica), sweet potato (Ipomoea batatas).

The results indicate that variety of New Zeland rabbits and hyrid rabbit between California x New Zealand eaten concentrate intake trends higher than that in others treatments. Therefore, total feed intake between treatments is different significantly and differences of  feed conversion ratio between treatments also are significant statistically. Otherwise, weaning weight, weight gain of the finishing rabbits is not different significantly. Also those results proved that different of varieties of F1 hydrid rabbits affected differently on feed intake and feed conversion ratio and efficiency of the experiment rabbits.

Key words: cross rabbits, birth weight, weaning weigh, feed intake, weight gain, para grass, water spinach, sweet potato.
