Increasing food production for the growing human population off a constraining land base
will require greater efficiency of production. Genetic improvement of feed efficiency in cattle …

Evolutionary biology provides reasons for why the intensive selection for milk production
reduces reproductive success rates. There is considerable exploitable genetic variation in …

Interest in improving feed efficiency in cattle is intensifying. Residual feed intake (RFI), which
is the difference between expected intake and that predicted based on energy demands, is …

Monitoring, recording, and predicting livestock body weight (BW) allows for timely
intervention in diets and health, greater efficiency in genetic selection, and identification of …

There have been considerable recent advancements in animal breeding and genetics
relevant to disease control in cattle, which can now be utilised as part of an overall …

Due primarily to a lack of phenotypic data, little research has been undertaken on the
genetics of reproductive performance in beef cattle. The objective of this study was to …

Large-scale animal husbandry currently serves as the primary source of protein and
essential nutrients for human consumption. Ensuring adequate access to animal weight has …

An equivalent computational approach called ssGTBLUP was formulated for the original
single-step GBLUP (ssGBLUP). In ssGTBLUP, the genomic relationship matrix has the form …

Livestock mature at different rates depending, in part, on their genetic merit; therefore, the
optimal age at slaughter for progeny of certain sires may differ. The objective of the present …

Background It has been challenging to implement genomic selection in multi-breed tropical
beef cattle populations. If commercial (often crossbred) animals could be used in the …
