Bovine chromosome 20 was screened to identify QTL for milk yield (MY), protein percentage (PP), protein yield (PY), fat yield (FY), fat percentage (FP), milk somatic cell count (MSCC), calving difficulties and perinatal mortality using a daughter design and a selective milk DNA pooling approach in the Italian Holstein breed. The results may confirm, even if indirectly, the effect of the growth hormone receptor (GHR) F279Y mutation on PP, FP and correlated traits. Other two putative QTL affecting PP, two affecting MY (as well as PY and FY) and MSCC, and two affecting reproductive traits have been identified.

Abstract
Bovine chromosome 20 was screened to identify QTL for milk yield (MY), protein percentage (PP), protein yield (PY), fat yield (FY), fat percentage (FP), milk somatic cell count (MSCC), calving difficulties and perinatal mortality using a daughter design and a selective milk DNA pooling approach in the Italian Holstein breed. The results may confirm, even if indirectly, the effect of the growth hormone receptor (GHR) F279Y mutation on PP, FP and correlated traits. Other two putative QTL affecting PP, two affecting MY (as well as PY and FY) and MSCC, and two affecting reproductive traits have been identified.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
