Breed Evaluation For Efficiency Of Feed Utilization For First Calf Production, D.M. Marshall, C.A. Dinkel
South Dakota Beef Report, 1988
Individual feed intake was measured in drylot on first-calf females for a 1-year period through weaning of their first calf. Dam breeds included crossbred Simmental-Hereford, Angus-Hereford, Salers-Hereford and Tarentaise-Hereford produced in two-breed rotations and straightbred Hereford. Cow weights were heaviest for Simmental-Hereford and lowest for Tarentaise-Hereford and straightbred Hereford. Calf weaning weights were heaviest for Simmental-Hereford and Lightest for straightbred Hereford and Angus-Hereford. Intake of cow feed TDN was highest for Simmental-Hereford cows and Lowest for Tarentaise-Hereford and straightbred Hereford. Breed group rankings for total cow feed and calf creep feed TDN intake were the same as rankings for cow …
