PERFORMAN PRODUKSI KELINCI NEW ZEALAND WHITE JANTAN DENGAN BAGASSE FERMENTASI SEBAGAI SALAH SATU KOMPONEN RANSUMNYA

Rabbits was livestock having potency to meat production. Feed of rabbits consisted of forages and concentrate. The price of commercial concentrate is expensive, so it is need feed alternative as concentrate substitution that move cheap, large of amount, and easy to get. One of example is cane pulp (bagasse). Bagasse are feed with low quality, because of high crude fiber and low protein, so it need fermentation with probiotic that can increase the nutrient content. The aim of this research was to find out of the effect of using fermentation bagasse in ration to the producing of New Zealand White male rabbits. This research was done two months, started from June 4th up to July 29th, 2008 in Breeding Centre of Rabbits, Agriculture Departement of Balaikambang Surakarta, used 16 head New Zealand White male rabbits age four month with the average weight of 1996 ± 188 gram. The feed is given consist of concentrat BR2 produce PT. Charoen Phokphand Indonesia, fermentation bagasse, and forages (peanut straw). The feed gived at 6,5% from body weight with ratio 60 : 40 percen (on dry matter). As for its treatment as P0 : Forages 60% + Concentrate 40% (control); P1 : Forages 60% + Concentrate 35% + Fermentation bagasse 5%; P2 : Forages 60% + Concentrate 30% + Fermentation bagasse 10%; P3 : Forages 60% + Concentrate 25% + Fermentation bagasse 15%. The variable measure wered is feed consumption, average daily gains, feed convertion , and feed cost per gain. The analysis is used variance analysis based on Completely Randomized Design (CRD) one way classification variancy analysis, if the result were significant between the treatments it will be followed by Duncan Multiple Range Test (DMRT). xi The result of research show average from four kinds of treatment P0, P1, P2, and P3 for feed consumption 143,57; 132,09; 129,34; 120,44 gram/head/day, average daily gains 24,22; 16,99; 16,77; 10,28 gram/head/day, feed convertion 6,09; 8,13; 8,00; 13,03, and feed cost per gain Rp 24967,56; Rp 32492,12; Rp 31213,28; Rp 49569,90. The result of variance analysis show that the feed consumption, average daily gains, and feed convertion from four kinds of treatment is highly significant (P
