Dear,

I need publications to discuss the "adaptation" of native (local) animal breeds to harsh environmental conditions. In a different aspect than usual. In particular, under poor feeding conditions when cows shorten lactation and not (or slightly) lose body weight. Which is the opposite to Holstein-Friesian and other high-yielding breeds. I know this is an archaic topic. I have some publications about adaptation of African breeds but there it rather concerns heat stress. Since it can be difficult to discuss about cattle I will be satisfied with other ruminant species as well.
