Abstract

An experiment was conducted to examine the effect of different levels of tape yeast addition into rations on Rattus norvegicus performance, such as feed consumption, body weight gain, feed conversion ratio and mortality. The experimental design used was a factorial completely randomized design 2 x 4, the first factor was sex (male and female rats), and the second factor was different levels of tape yeast added into rations (0% as R1, 0.5% as R2, 1% as R3 and 1.5% as R4). The results showed that the interaction between sex and yeast addition had significant effect on feed consumption and body weight gain (P < 0.05), but the effect was not significant on feed conversion ratio and mortality. Yeast addition in male-rat rations significantly reduced feed consumption, but did not affect body weight gain. In female rats, the addition of yeast in the rations increased body weight gain. Increasing levels of tape yeast in the rations improved the body weight gain and feed conversion ratio, especially for female rats (P < 0.05). There was no single rat died during the experimental period. Rats fed ration containing 1.5% yeast showed better feed consumption, weight gain, and feed conversion ratio compared to rats given other rations. Key words : rat, tape yeast, consumption, weight gain, feed conversion ratio, mortality

Abstract

Most feed for goats in the villages of West Timor, Indonesia, came from communal grazing areas, consist of native grass during wet season, crop residues and tree leaves (Sesbania and Acacia species) in dry season. This study was aiming at examining the growth of goat supplemented with local feed. Twenty four goats were used, the average initial live weight was 12.5 kg. Four feeding treatments were applied: T1-200 g cut grass; T2-200 g Acacia villosa; T3-200 g Coripha gebanga; T4-100 g A. villosa + 100 g  C. gebanga. Live weights and feed consumption were analyzed using repeated measures, analysis of variance. The average live weight showed a small increase, as well as daily weight gain of goats of which different significantly (PA. villosa, C. gebanga, and A. villosa plus C. gebanga, respectively. Goats given C. gebanga and mixed Acacia and C. gebanga gave higher average weight gain, but also consumed more feed than those given cut grass or A.villosa (P < 0.01). Supplementing feed to maintain growth of goats during dry seasons was better on A. villosa than on palm pith and its combination.

Abstract

Study on intensification program through reproduction and feeding management was conducted for six months to evaluate the growth and reproductive performance of wild silkworm, Attacus atlas. The experiment was divided into two phases: 1) the first phase was conducted on mating management, by applying different times of mating duration of 3, 6, 12, and 24 h as treatments to assess eggs production. In this phase, a completely randomized design was used, with 4 treatments and 5 replications; 2) the second phase was on feeding management, a completely randomized design method (2 x 2) was used, including feed (guava and walnut leaves) as first factor, and the second factor was feeding times (3 and 4 times/day) with 5 replications. The results obtained from the first experiment showed that different duration of mating significantly (P<0.05) affected the number of eggs produced. Based on time efficiency 6 hours mating duration produced higher egg production (226 egg/cycle), as well as hatchability (95%) than those of other mating duration. In the second experiment, it was found that there was interaction between feed types and feeding frequencies which significantly (P<0.05) affected feed consumption, feed digestibility, body weight gain, diameter of larvae and mortality rate. In conclusion, the optimum and efficient duration sugested for mating is six hours resulting high egg production. The walnut leaves feed has better effect on the first and second instar of larvae, while the guava leaves affect the following instars. In terms of production, four times of feeding frequency per day has higher productivity and is recommended in the cultivation management of A. atlas.
