Effect of Charolais dams´ mating method and parity on growth ability of their progeny

Original language description

The objective of this study was to determine the growth ability of Charolais bulls and heifers during the rearing period in relation to the sex of the animals, occurrence of twins, mating methods and parity of dams. A total of 584 animals born were observed in three herds of Charolais suckling cows from January 2000 to March 2007. The live weight at birth (BW) and at 120 (W120), 210 (W210) and 365 days (W365) of age in relation to herd-year-season, sex, occurrence of twins, mating method, and the dams´parity were evaluated. The statistical significances of the model used for evaluation were in all cases P < 0.0001, and the coefficient of determination ranged from r2=0.5012 to r2=0.7867. Differences in all live weights were significant (P < 0.001) in favour of bulls. Twins achieved lower live weight during the entire period, but it was significant only from birth to 210 days of age (P < 0.0001). It was confirmed that proven AI sires used in mating result in a higher growth ability of o
