Summary

This narrative review examines seasonal fluctuations in ruminant nutrition across Southern African farming systems and their implications for household and regional food security. The authors identify critical knowledge gaps in understanding how seasonal feed availability and nutritional quality constraints affect livestock productivity and, by extension, food security outcomes in the region. The work suggests that targeted interventions addressing seasonal nutritional gaps could enhance both animal productivity and food system resilience.

UK applicability

Whilst UK temperate grazing systems differ substantially from Southern African conditions, the framework for understanding seasonal nutritional constraints in ruminants and their food security implications may inform strategies for seasonal feed planning and nutrient supplementation in UK pastoral systems.

Key measures

Seasonal nutritional adequacy in ruminants; livestock productivity metrics; food security indicators; knowledge gaps in ruminant nutrition management

Outcomes reported

The study identified seasonal variations in ruminant nutrition across Southern African farming systems and documented knowledge gaps affecting food security outcomes. It likely synthesised evidence on how nutritional deficiencies in livestock seasonally impact productivity and household food security.
