Abstract

This study aimed to evaluate the supplementation of encapsulated fermerherbafit on feed intake and final body weight of male Sentul chickens. The study used 60 male white Sentul chickens, housed individually in battery cages and raised for 30 days. A Completely Randomized Design (CRD) was employed, consisting of five treatment groups with four replications each. The treatments were as follows: R0: 0% fermerherbafit supplementation (control), R1: 2% non-encapsulated fermerherbafit supplementation, R2: 2% encapsulated fermerherbafit supplementation, R3: 4% encapsulated fermerherbafit supplementation, and R4: 6% encapsulated fermerherbafit supplementation. Data were analyzed using analysis of variance (ANOVA). The average daily feed intake of male Sentul chickens ranged from 75.22 g/bird/day to 78.45 g/bird/day, with an overall average of 77.00 g/bird/day. The final body weight ranged from 1,417 g/bird to 1,540 g/bird, with an overall average of 1,469 g/bird. The results of the variance analysis indicated that fermerherbafit supplementation had no statistically significant effect on feed intake or final body weight of male Sentul chickens. The study concluded that supplementation of encapsulated fermeherbafit up to a level of 6% in the feed did not significantly affect feed intake and has not yet been able to increase the final body weight of Sentul male chickens.

Abstract

This study aimed to investigate the effect of different levels of acetic acid solution application on duck eggs on eggshell strength and hatching time. The materials used in this study were 180 hatching duck eggs (1–7 days old, weighing 65–75 g) from 16–18week old parent ducks. An experimental method with a Completely Randomized Design (CRD) was employed as the research design. The study consisted of three acetic acid treatment groups (P0: 0%, P1: 10%, P2: 20% acetic acid) and 6 replicates, with each experimental unit using 10 eggs. The variables measured in this study were eggshell strength (MPa) and egg hatching time (hours). Eggshell strength and hatching time data were analyzed using analysis of variance (ANOVA) and orthogonal contrast as a post-hoc test. The results showed the mean values of eggshell strength (MPa) for each treatment as follows: P0 (0.233 ± 0.022), P1 (0.125 ± 0.013), and P2 (0.144 ± 0.031); and hatching time (hours): P0 (650.438 ± 9.714), P1 (622.438 ± 5.519), and P2 (635.503 ± 2.182). Analysis of variance revealed a highly significant difference (P<0.01) in both variables due to the acetic acid application. Orthogonal contrast tests showed no significant difference in eggshell strength between treatments P1 and P2, while there was a highly significant difference (P<0.01) in hatching time between P1 and P2. It can be concluded that acetic acid application significantly reduces eggshell strength and accelerates the hatching of duck eggs. The treatment with a 10% acetic acid concentration demonstrated the most optimal effectiveness in accelerating hatching.

Abstract

This study aims to analyze the effects of quantitative production parameters on the Performance Index (PI) of broiler chickens. Five key variables were examined: mortality, culling, feed conversion ratio (FCR), final body weight, and harvesting age. The analysis utilized secondary historical data from 17 production cycles of broiler chickens at PT XYZ between 2021 and 2023. Multiple linear regression was employed after satisfying classical assumption tests. Results indicate that all independent variables significantly influenced PI both simultaneously (p < 0.05) and partially. The adjusted R-squared value of 99.81% demonstrates that the model explains nearly all variation in the performance index. Partially, final body weight had the highest positive impact on PI (coefficient +223.11), followed by FCR (-184.84), harvesting age (-10.41), culling (-3.61), and mortality (-3.238), all with negative effects. These findings highlight the critical role of production parameter control in optimizing broiler performance efficiency.
