The development of a commercialised breeding value for footrot resistance represents a "huge opportunity" for the expansion of fine wool sheep production, the New Zealand Merino Company says.
While "not a silver bullet" against the disease which results in lameness and loss of production, it would allow growers to make genetic gains and establish flocks that were footrot resistant, NZM chief executive John Brakenridge said.
Growers would save money from reduced treatment costs and chemical inputs, would not be hit with lower production, all while improving animal welfare.
It was the result of work by the New Zealand Sheep Transformation Project, co-funded by NZM and the Ministry for Primary Industries with a contribution from Merino Inc, to look at ways to contribute to a more productive, profitable and high animal welfare future for fine wool.
Such a breakthrough was huge as it allowed fine wool flocks to thrive on farms that had traditionally been used for strong wool production, he said.
