In Australia, agriculture is responsible for~ 17% of total greenhouse gas emissions with
ruminants being the largest single source. However, agriculture is likely to be shielded from …

Despite substantial advances in milk production efficiency of dairy cattle over the last 50
years, rising feed costs remain a significant threat to producer profitability. There also is a …

Background Single nucleotide polymorphism (SNP) arrays for domestic cattle have
catalyzed the identification of genetic markers associated with complex traits for inclusion in …

We report mapping of a quantitative trait locus (QTL) with a major effect on bovine stature to
a∼ 780-kb interval using a Hidden Markov Model–based approach that simultaneously …

Feed makes up a large proportion of variable costs in dairying. For this reason, selection for
traits associated with feed conversion efficiency should lead to greater profitability of …

Providing feed is a major input cost in beef production, hence improvements in the efficiency
of feed utilisation will reduce the cost of production. Residual feed intake (RFI) is a measure …

ABSTRACT A genome wide-association study for production traits in cattle was carried out
using genotype data from the 10K Affymetrix (Santa Clara, CA) and the 50K Illumina (San …

Feed efficiency is an economically important trait in beef production. It can be measured as
residual feed intake. This is the difference between actual feed intake recorded over a test …

Background In a previously reported genome-wide association study based on a high-
density bovine SNP genotyping array, 8 SNP were nominally associated (P≤ 0.003) with …

The cow herd consumes approximately 70% of the annual feed resources. To date, most
genetic evaluations of feed intake in beef cattle have been made in growing animals and …
