Proximate analysis of local ingredients as a prospective resource for feed production in Bangladesh

The proximate composition of local feedstuffs cost-effective for livestock and aqua feed formulation and production is mainly unidentified among different farming stakeholders.This study was conducted to investigate the proximate analysis and the market price of 230 samples of 18 different local ingredients collected from various areas in Bangladesh.Among the assessed energy and protein sources local ingredients, all the proximate components were statistically significant (P≤0.05).The broken rice had higher moisture, crude protein, ether extract, and nitrogen-free extract content in the energy source ingredients.In contrast, B-grade rice polish had a high crude fiber content (20.12±2.26%)and ash (18.76±1.27%).Animal-based protein sources ingredients, such as shrimp meal (16.33±0.99%moisture), fish meal (57.80±1.26%crude protein), mixed dry fish (22.91±1.49%crude fiber and 31.17±1.36%ash), crab shell (40.57±1.28%nitrogen-free extract), and plant-based full-fat soybean (18.57±1.03%ether extract) comprised the considerable proportion of proximate components.For per-unit protein cost, soybean meal was a cheaper protein source followed by mustard oil cake, full-fat soybean, and sesame oil cake, while the fish meal was found as an expensive protein source ingredient.This research revealed that local ingredients could be utilized for livestock and aqua farming to produce cost-effective, high-quality feeds.
