Summary

This paper reviews seasonal fluctuations in the quantity and quality of feed available to ruminant livestock in Southern Africa, examining how periodic nutritional deficits — commonly termed the 'feed gap' — undermine animal productivity and household food security. Drawing on existing literature, the authors identify significant knowledge gaps regarding the magnitude, timing, and nutritional consequences of these gaps across the region. The review is likely to inform research priorities and intervention strategies for improving livestock-based food systems in resource-limited contexts.

UK applicability

The findings are primarily relevant to smallholder and pastoral livestock systems in sub-Saharan Africa and have limited direct applicability to UK farming conditions; however, they may inform UK-based development programmes, international aid policy, and research agendas focused on food security in low-income countries.

Key measures

Seasonal feed availability; forage nutritive value (e.g. crude protein, digestibility); livestock body condition; identified knowledge gaps; food security indicators

Outcomes reported

The study likely characterised seasonal variability in feed quality and quantity available to ruminants in Southern Africa, identifying critical periods of nutritional deficit and highlighting knowledge gaps relevant to livestock-dependent food security. It probably assessed how these feed gaps affect animal productivity and, by extension, the livelihoods and nutrition of farming communities.
