Background Birth weight (BW) is an economically important trait in beef cattle, and is
associated with growth-and stature-related traits and calving difficulty. One region of the …

The objectives of the current study were to investigate the additive genetic associations
between heifer pregnancy at 16months of age (HP16) and age at first calving (AFC) with …

The objective of this study was to estimate (co) variance functions using random regression
models on Legendre polynomials for the analysis of repeated measures of BW from birth to …

Data from 23,120 Nellore animals were used to estimate genetic parameters for age at first

The objective of this study was to investigate the association of single nucleotide
polymorphisms (SNPs) with birth weight, weight gain from birth to weaning and from …

Body weight is an important economic trait for sheep meat production, and its genetic
improvement is considered one of the main goals in the sheep breeding program. Identifying …

Records of beef cows from a ranch in southern Mexico gave 1967 birth weights (BW), 1587
weaning weights adjusted to 210 days of age (AWW) and 2001 calving intervals (CI) for the …
