Random regression analysis of milk yield and milk composition in the first and second lactations of Murciano-Granadina goats [PDF]
Journal of Dairy Science, 2010 Records from the milk recording scheme of Spanish Murciano-Granadina goats were studied to estimate genetic (co)variance components and breeding values throughout the first and second lactations. The data used consisted of 49,696 monthly test-day records of milk (MY), protein (PY), fat (FY), and dry matter (DMY) yields from 5,163 goats, distributed in ...
