Abstract

This study aims to determine the differences in broiler chicken performance across five rearing periods by analyzing the variables of average body weight, depletion rate, feed conversion ratio (FCR), performance index (IP), and Income Over Feed Cost (IOFC). Data collection techniques used in this research include observation and questionnaires, with the subject being the close house system at Suyatno Farm. The study produced the following: averages over five rearing periods: an average pololation 19,800 chickens, an average body weight of 1.98 kg per bird, a depletion rate of 385 birds or 1.94%, a feed conversion ratio of 1.437, a performance index (IP) is 441, and IOFC IDR 14,005. The results indicate that Period 1 had the best overall performance in terms of average final body weight 2.1 kg per bird, performance index 473, and IOFC IDR 14,660. Period 2 showed the best result in depletion rate, with 348 birds lost 1.65%. Meanwhile, the best feed conversion ratio was recorded in Period 3 with a value of 1.410.

Abstract

This study aims to analyze the performance of hybrid broiler ducks with the addition of fermented corn cob flour to their feed. An experimental method was used for this study. This study used 36 1-week-old hybrid broiler ducks and were raised for 4 weeks in a completely randomized design (CRD) with 4 treatments and 3 replications. The hybrid ducks were fed fermented corncob meal at percentages of 0%, 2%, 4%, and 6% as part of the treatment. Feed Consumption (FI), Body Weight Gain, and Feed Conversion Ratio (FCR) were some of the variables examined. Analysis of Variance (ANOVA) was used to examine the research data, and Duncan's Multiple Range Test (DMRT) was used to test the results at a 5% significance level. The research findings showed that Feed Consumption (FI), Body Weight Gain, and Feed Conversion Ratio (FCR) of hybrid ducks were not affected by the addition of fermented corncob meal to the feed.

Abstract

This experiment aims to evaluate the effectiveness of inoculation and synergy of Arbuscular Mycorrhizal Fungi (AMF) and Trichoderma harzianum on the growth, productivity, and effectiveness of inoculation of Alfalfa (Medicago sativa L.) forage in marginal land in the early phase of the first regrowth. This experiment used biological agents, mycorrhizae, and Trichoderma. This study used a completely randomised design with a one-way pattern consisting of four treatments and five replications, namely T0: without inoculation; T1: Mycorrhizae 300 spores/polybag; T2: Trichoderma 5 grams, 1 × 106 spores/gram; T3: Combination of Mycorrhizae 300 spores/polybag and Trichoderma 5 grams, 1 × 106 spores/gram. Data were analysed using Analysis of Variance (ANOVA). The results showed that AMF inoculation in treatment T1 had a significant effect (p <0.05) on plant length (cm), number of branches (strands per branch), fresh biomass of the canopy and the effectiveness of inoculation. Treatments T2 and T3 were not significantly different from T0 (p>0.05) regarding plant length, but the number of branches differed. T2 and T3 showed significant differences (p<0.05), which were higher than the control, but not with the results of fresh shoot biomass and inoculation effectiveness. T2 gave insignificant results and was not better than treatments T1 and T3. Mycorrhizal inoculation T1 positively responded to plant growth, fresh shoot biomass and inoculation effectiveness under drought stress, although the combination treatment T3 also provided good feedback.
