Estimates of genetic correlations between testicular measurements and female reproductive traits in cattle.
Data from 528 male and 645 female progeny of 63 sires were used to estimate genetic correlations between female and male reproductive traits. Data were from two Hereford herds involved in a long-term… Expand

Litter (n = 8,424) and female performance records were collected in two breed-to-wean production units in order to evaluate genetic line differences for sow longevity and maternal performance over… Expand
Estimation of additive and nonadditive direct and maternal genetic effects from crossbreeding beef cattle.
Effects of cytoplasmic inheritance on production traits of dairy cattle.
Pedigrees of 4461 cows were traced to the original female in a maternal line. Cytoplasmic origin was defined as the first female in the maternal lineage. There were 102 cytoplasmic lines. Most cows… Expand
The influence of maternal effects on the efficiency of selection; A review

- 1 April 1981
Abstract The experimental evidence concerning the existence and importance of maternal effects in beef cattle, dairy cattle and swine is reviewed. It is clear that maternal effects are important in… Expand

Results from nine generations of selection for increased litter size in swine.
Direct selection for increased litter size was done for nine generations. The select line consisted of approximately 15 sires and 60 dams per generation, and selection was based on estimated breeding… Expand
Milk yield and its influence on 205-day weight of beef calves.
Evaluation of procedures to predict fat-free lean in swine carcasses.
The objectives were to develop equations for predicting fat-free lean in swine carcasses and to estimate the prediction bias that was due to genetic group, sex, and dietary lysine level. Barrows and… Expand
