Effect of Litter Size on Lamb Mortality

Litter size significantly influences lamb mortality rates, with 6% to 28% mortality observed across different groups. Mortality increases with extreme lamb weights—below 3.5 kg or above 7 kg—due to higher lambing difficulty and labour demands. This visual illustrates the correlation between litter size, lamb weight, and mortality, emphasizing the need for farmer awareness to improve nutritional and management practices and reduce mortality.
