Utilization of biological silage from shrimp processing waste as a sustainable practice in productive performance of broiler chickens

The use of aquaculture by-products transformed into biological silage represents a environmental sustainable alternative for improving the efficiency and performance of broiler production systems. However, scientific evidence regarding the efficacy of biological silage formulated from Penaeus vannamei waste in broiler nutrition remains scarce. Therefore, this study aimed to assess the effects of biological silage fermented with native bacteria on the production performance, conversion efficiency feed, and intestinal health of broiler chickens during the growth and finisher phases, conversion efficiency, and intestinal integrity of broiler chickens during the grower and finisher stages. A completely randomized design with a Tukey multiple comparison test was used with four treatments (0 %, 10 %, 15 %, and 20 % of biological silage). The variables evaluated included body weight gain, feed conversion ratio, apparent digestibility, carcass yield, economic merit, and gut morphology. In conclusion, the use of P. vannamei biological silage fermented with native bacteria represents a sustainable and cost-effective nutritional strategy that improves broiler performance, promotes sustainable production using aquaculture processing waste, and reduces production costs, offering a nutritious and functional feed.
