This experimental study was conducted to investigate the growth performance of broiler chicken Cobb 500 (Gallus gallus domesticus) fed with varying levels of vegetable remnants which consist of chayote, carrots, and cabbage. Randomized Block Design (RBD) with three treatments and three
replications was used as design in this study.
The researchers utilized Analysis of Variance (ANOVA) as the statistical
method in evaluating the data of the study. The researchers decided to carry out
their experimental study at the University of Rizal System - Roriguez Campus. The experiment was conducted for about 135 days, from October 6, 2023 to February 31, 2024. 45 heads of chicken were used as experimental animals.
The subjects of the study were divided into three treatments: treatment 1 -
fed with pure commercially feeds; treatment 2 - fed with 50% vegetable remnants
(chayote, carrots, cabbage) and 50% commercially feeds; and treatment 3 - fed with 30% commercially feeds and 70% vegetable remnants (chayote, carrots,
cabbage).
This research investigated how varying amounts of vegetable remnants affect broiler chicken growth. Using comprehensive statistical analyses, the study
examined average gain weight, feed conversion efficiency, feed consumption,
water consumption, and market weight. While average gain weight remained similar across different dietary groups, significant differences emerged in how efficiently feed was converted, feeding and water consumption patterns, and the final market weight of the chickens. These findings highlight the clear impact of vegetable remnants on feed utilization, water intake, and market weight. In essence, the study reveals a trade-off: incorporating vegetable remnants improves feed conversion efficiency but potentially reduces overall average gain weight and market weight. Despite this slight decrease in average gain weight, diets containing vegetable remnants offer cost advantages due to lowered feed costs.
Additionally, the study suggests a possible link between lower weight gain and the use of vegetable remnants, potentially impacting feather development. Further
research is needed to fully understand the growth dynamics of broiler chickens fed with vegetable remnants, ultimately leading to optimized feeding practices for enhanced production efficiency.
