“…They estimated the heritability of BTW as 0.46 and the heritability of CW as 0.64. Our data consisted of animals born from 1990 to 2002, and our estimates of heritability are consistent with those of Groen and Vos (1995), but higher than those of Lee et al (1992). Higher heritabilities obtained from both this analysis and the analysis of Groen and Vos (1995) may well be a result of the uniform recording conditions under which both sets of data were collected.…”

“…Lee et al (1992), in an analysis of 1,266 Holstein cows born between 1972 and 1983, estimated the heritability of BW at first calving as 0.33, and the heritability of BW gain from 0 to 8 wk of age as 0.24. Groen and Vos (1995) analyzed BW data taken at various time points from birth to first calving on 631 Dutch Black and White animals born from 1983 to 1990 using an animal model. They estimated the heritability of BTW as 0.46 and the heritability of CW as 0.64.…”

“…However, growth in dairy cattle has not been studied so extensively, particularly the genetic component of growth. Groen and Vos (1995) estimated the heritability of growth at different stages prior to first calving in Holstein heifers, and Korver et al (1991) estimated genetic parameters for feed intake and feed efficiency in growing Holstein heifers. Demeke et al (2003) estimated heritabilities for BW at various stages of life for a range of European and indigenous breeds and their crosses in Ethiopia.…”

In general, genetic selection is applied after first calving to traits that manifest themselves during the animal's productive life, mostly during the early part of productive life. This selection policy has had undesirable correlated responses in other economically important traits, such as health and fertility, and may also have had an effect on the growth of animals both during productive life and before first calving. In this study, we analyzed the growth trajectory of dairy heifers that had been selected for maximum production of combined fat and protein (measured in kg; select line) or for average production (control line) in the United Kingdom. Before first calving, these divergent lines were managed as a single group. Select line heifers grew faster than did control line heifers. They were also heavier at first calving, but by the end of 3 lactations, the lines were not significantly different in live weight. Selection primarily for yield and for other traits has led to heifers that grow faster and reach higher growth rates earlier in life. A genetic analysis of birth, weaning, and calving weights yielded heritability estimates of 0.53 (birth weight), 0.45 (weaning weight), and 0.75 (calving weight). Confidence intervals for the genetic correlations between the traits indicated that these BW traits are not under the same genetic control.

“…These heritability estimates are from a small data set and apply to all genetic groups, which were fit as fixed effects in the model. Some recent estimates of heritabilities for birth weight range from 0.46 to 0.53 (Groen and Vos, 1995;Coffey et al, 2006). Jamrozik et al (2005) found the heritability for gestation length (analyzed as a trait of the calf) in Holsteins to be 0.22, whereas VanRaden et al 2004reported an estimate of 0.10.…”

Holstein and Jersey cows were mated to 4 Holstein (H) bulls and 4 Jersey (J) bulls to create HH, HJ, JH, and JJ genetic groups (sire breed listed first) in a diallele crossbreeding scheme. Calvings (n = 756) occurred in research herds in Virginia, Kentucky, and North Carolina with 243, 166, 194, and 153 calvings in the HH, HJ, JH, and JJ groups, respectively. Birth weights (BW), dystocia scores (0 for unassisted and 1 for assisted), and stillbirth (0 for alive or 1 for dead within 48 h) were recorded at calving. Gestation lengths (GL) were determined from breeding dates. An animal model was used to analyze BW and GL, and an animal model with logistic regression was used for dystocia and stillbirth. Fixed effects considered for model inclusion were genetic group, herd-year-season, sex, parity (primiparous or multiparous), twin status, and gestation length. Genetic group and effects significant in the model building process were kept in the final model for each trait. Heifer calves had lower BW, shorter GL, and had a lower odds ratio (0.53) for dystocia than bull calves. Twins had lower BW, shorter GL, were 3.86 times more likely to experience dystocia, and 7.80 times more likely to be stillborn than single births. Primiparous cows had calves with lower BW, shorter GL, were 2.50 times more likely to require assistance at birth, and were 2.35 times more likely to produce stillborns than calves from multiparous cows. Genetic group did not affect GL. Least squares means (kg) for BW were 37.7 +/- 1.1, 29.1 +/- 1.1, 30.3 +/- 1.0, and 22.5 +/- 1.3 for HH, HJ, JH, and JJ, respectively. Animals in HH weighed more than animals of other genetic groups; the JJ group had the smallest BW, with no differences for BW between HJ and JH. Probability of dystocia in JJ and JH were 5.73% and 18.98% of HH. Calves in HJ and HH were not different for dystocia. Calves in HJ were 3.38 times more likely to be stillborn than calves in JH, but no other genetic group differences were significant for probability of stillbirth. Groups HJ and JH differed for calving traits, with JH crosses experiencing less dystocia than HJ; JJ showed no indication of dystocia. No differences were observed between HH and JJ for stillbirths. Additional investigation of stillbirths in Jerseys is justified.

“…This means that there is a connection between calving age and weight. Growth and weight are highly heritable, and Groen and Vos (1995) found heritabilities for growth from birth to 50 weeks at 48% and heritabilities for weight at breeding and calving at 41% and 64%, respectively, while Coffey et al (2006) found a heritability for calving weight at 75%. The growth is the driver toward sexual maturity and also explains the very high correlation between AFI and AFC.…”

Our aim was to investigate whether four fertility traits were different in herds using the activity tag Heatime for reproduction management compared within other herds. The genetic parameters were estimated using animal models. The fertility traits were number of inseminations (NINS), interval from first to last insemination (IFL), age at first insemination (AFI), and age at first calving (AFC) in Danish Holstein heifers. The means of the traits were all significantly different between the two groups of herds. Heritabilities for NINS and IFL were lower than 1%, while heritabilities for AFI and AFC were 12-29%. Heritabilities were all lower in Heatime herds than in reference herds. The genetic correlations between traits in different environments were high for NINS, AFI, and AFC (>0.88), while the correlation for IFL was 0.68 but with a higher SE (0.313). Thus, IFL seems not to be the same trait in Heatime and reference herds.
