Abstract

fetched live from OpenAlex

Demand for maize in Bangladesh is increasing day by day for its diversified use in poultry, fish, and animal feed, processed foods, and export markets. The present study deals with the maize marketing system in Rangpur district with a focus on different categories of intermediaries that participate, and the determination of problems associated with the marketing process. The current study was undertaken in 2024 through face-to-face interviews with 30 maize producers, 40 intermediaries, and five feed millers. Seven marketing channels were clearly identified, involving the following as intermediaries: Farias, Beparis, Wholesalers, and Wholesaler-cum-Aratdars. Profit margins varied across channels. The producer-to-feed miller channel earned a profit of BDT 286, while the producer to wholesaler-cum-aratdar to feed miller channel earned a profit of BDT 503, respectively. Similarly, per maund (40 kg) marketing cost also varied from BDT 145 to BDT 173 in the marketing channels. Beparies obtained the highest return because of their end-to-end processing of maize. The marketing challenges were price fluctuations and nutrient-based grade disparities, to meet the same Metabolism Energy (ME) requirement using Grade B maize, an additional Tk. 22 per maund is incurred. Furthermore, the crude protein analysis demonstrates that balancing the CP content equivalent in one maund of feed requires an additional Tk. 186 when using Grade B maize compared to Grade A maize. This study has pointed out a remarkable influence of marketing channels on profit margins and feeding production costs of feed millers. It suggests focusing on the intermediaries for overcoming the existing marketing challenges and optimizing the maize grading for efficient and cost-effective feed production.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
