In this review, we describe and illustrate the selection and use of some appropriate regression models for bivariate statistical relationships. The most commonly used method, ordinary least squares (OLS) or type I regression, may be inappropriate when the predictor variable is subject to...

Animal welfare is a growing scientific field that is constantly changing and improving. The importance of this field is becoming more evident in all production agriculture settings, including cattle and dairy production units. In 2007, Fraser defined animal welfare as a 'mandatory science', one in...

Increasing the efficiency of conversion of feed nitrogen (N) into milk and meat N in dairy cattle is an integral part of the effort to maintain or increase food production while decreasing agriculture's environmental impact. Mathematical models provide a means to assess and compare different...

The efficiency with which dairy cows convert feed to milk impacts farm profitability and environmental stewardship. Thus, feed efficiency is a particularly critical trait to the dairy industry as feed costs increase. Feed efficiency is a complex trait influenced by many components, including milk...

Genetic analyses of milk production traits have been based on a polygenic model that assumes that a trait is affected by an infinitesimal number of genes each with a very small effect. An updated review on the genetic parameters (heritabilities and genetic correlations) for milk components...

Cultivated compost housing systems for dairy cattle are reported in the literature from Israel, the USA and the Netherlands. A deep-bedded pack is commonly supported by large amounts of wood shavings and sawdust to enhance microbial activity and evaporation. Aerobic composting processes are...

Dairy heifers, particularly when <3 months, are at high risk for mortality and morbidity. Accurate data are lacking because of poor recording on farm, difficulties over disease diagnosis and potential bias of farm selection. Mortality during rearing varied from 6 to 14% between studies. The...

Genomic or whole-genome selection represents a technological development in the use of a large number of genetic markers for genetic improvement, which is expected to lead to a paradigm shift in the design and implementation of livestock breeding programmes. Genomic selection (GS) is based on the...

Most applications of genomic selection (GS) have so far been in animals, especially dairy cattle, although theoretical studies have also been conducted for maize. For the last 50 years, commercial breeding programmes for dairy cattle have been based on the progeny test scheme, which results in an...

Increasing the digestibility of ruminant diets and thereby improving nutrient efficiency is an important aspect of ruminant nutrition. This improvement in nutrient utilization must initially come from an improved rumen digestion and utilization. Yeast products have been added to the diets of...
