There is good evidence that cattle vary in the size of the buffalo fly (BF) burdens they carry and that this variation is heritable. However, phenotyping cattle to enable selection for resistance is labour intensive and frequently inaccurate, largely because of the propensity of BF to redistribute amongst hosts when disturbed. This poster discusses the relative accuracy of different approaches to visual and photographic phenotyping for BF numbers, the use of behavioural response to predict BF susceptibility and the potential use of proteomic measures as biomarkers for resistance. Determination of more accurate and desirably, automated methods for phenotyping cattle could assist the implementation of effective and practical approaches for breeding for increased BF resistance.
