Effect of Spirulina supplementation effects on haematological biomarkers of lamb productivity

Spirulina (Arthrospira platensis) is a protein-rich and highly nutritious cyanobacterium which is a recognised livestock feed supplement (Holman & Malau-Aduli 2013). Protein supplementation to lambs generally results in a positive shift in productivity, liveweight and growth. These effects can be objectively assessed using specific haematological biomarkers (Braun et al 2010). The emergence of Spirulina supplementation has made it necessary to investigate its effects on haematological biomarkers of productivity.
