Abstract
Beef cattle production in Mozambique faces productivity constraints due to heat stress, limited adoption of sustainable practices, and use of non-adapted breeds. This study integrated systematic review (n = 57 publications), bibliometric analysis, and mixed-effects meta-analysis (n = 15 studies, 578 animals) to quantify the effects of breed adaptation and production system sustainability on daily weight gain in Mozambican cattle. Adapted breeds (Landim, Nguni, Angoni) showed significantly higher weight gain (+ 0.278 kg/day, p < 0.05) compared to non-adapted breeds, while sustainable management practices (shading, rotational grazing, improved feeding) added + 0.194 kg/day. The final predictive model explained 98.3% of observed variability (R²=0.983) with low prediction error (RMSE = 0.124 kg/day). Adapted breeds under sustainable systems achieved the highest predicted weight gain (0.78 kg/day), approaching commercial viability (0.8 kg/day), whereas non-adapted breeds under traditional systems showed the lowest performance (0.31 kg/day). Geographic distribution revealed research concentration in southern/central regions (82.5% of studies) and underrepresentation of northern Mozambique. These findings demonstrate synergistic benefits of aligning genetic adaptation with sustainable management, supporting evidence-based policies for resilient beef production in Mozambique and similar tropical systems.
