Native and locally adapted livestock breeds can contribute to biodiversity, rural livelihoods and food system resilience, but their conservation depends not only on genetic value or cultural narratives. It also depends on whether producers, processors, retailers and food-service actors can integrate them into viable production and commercialization systems. Based on data from 28 value-chain participants engaged through semi-structured interviews and sectoral focus groups, this qualitative study analyzes how sanitary risk, carcass performance, supply continuity, price formation and market trust shape the adoption prospects of Mexican Creole pig products. Participants represented six types of value-chain actors: industrial pig breeders, small butchers, restaurateurs, traders/distributors, dairy/cheese producers and meat processors without herds. Results indicate a structural misalignment between conservation-oriented innovation proposals and the operational logic of real value-chain actors. Creole pigs are perceived as slower-growing, fattier and less predictable than industrial pigs, which limits their suitability for mainstream pork markets. However, actors identify potential in small-volume, high-value niches such as food festivals, specialty retail and artisanal processed products, provided that traceability, sanitary guarantees and coordinated branding are ensured. The study concludes that Mexican Creole pig conservation through food innovation requires more than consumer interest: it depends on value-chain coordination, institutional support and market designs that align heritage, sustainability and economic feasibility.

Black soldier fly larvae (BSFL) (Hermetia illucens) were reared on faecal sludge and organic waste, harvested at the pre-pupal stage, and defatted to produce a protein rich feed ingredient. Three isonitrogenous diets (30 % crude protein) were then formulated such that BSFLM substituted FM at 0% (control, diet 1), 50% (diet 2) and 100% (diet 3) on a protein basis. Nutritional chemical analysis on ingredients and diets were determined while diets’ fatty acids profile was determined by MPA FT-NIR spectrometer. The analysis showed significant differences (p < 0.05) among the diet treatments for all measured parameters except dry matter. FM registered the highest crude protein, (57.89%) followed closely by defatted BSFL (54.69%). However, partial substitution of FM with defatted BSFL in diets increased crude protein levels (31.77%), registered moderate crude fat (5.26%) and moderate crude fibre (11.08%) (diet 2) levels compared to FM meal diet (diet 1). Consequently, partial substitution yielded the highest overall polyunsaturated fatty acids (ƩPUFAs) content (4.81 mg/g). Thus, the study shows that, partial replacement (50%) of FM with defatted BSFLM provides rich proximate and fatty acid profiles that can support Nile tilapia production while sustainably managing waste, promoting resource recovery within a circular economy.
