Resistance of the Brahman x AIS increased from 98.4% to 99.3% in the breeding herd and from 97.6% to 99.6% in the progeny. Female calves of both breeds were more resistant than males.doi:10.1111/j.1751-0813.1982.tb02684.xK. B. W. Utech...
Dairy Shorthorn cows are still being milked commercially in many herds Because of their blending ability with other red dairy breeds and the high protein quality of milk produced they could be a big plus in your herd. With careful selection they will also add size and scale. As one of the...
In a study of just under 900 Australian Cattle Dogs, published in 2012, over 10% of Blue Heelers had some degree of deafness. 3% of all the dogs were deaf in both ears. (paid link) An association between coat color and deafness has been noted in several breeds but the pattern and ...
An Australian Illawarra Shorthorn herd of 24 cows was mated in three consecutive years with an AIS bull. The cows and their progeny were rated for tick resistance at frequent intervals from August 1959 to December 1965 by counting the numbers of semiengorged female ticks on the right side. Th...
In general, for both breeds the use of DTD from domestic sources and DRP from Interbull in a single trait or bivariate model can increase reliability of DGV for selection candidates. Key words genomic prediction; daughter trait deviation; deregressed proof; reliability Corresponding author ...

An analysis of test records from herds in three dairy areas within Australia was undertaken to describe regional and breed differences in protein concentration of milk and to gain insight into factors responsible. Two breeds (Holstein/Friesian (H/F) and Jersey) and three regions (The Riverina, ...
The reliability of genomic prediction is influenced by several factors, including the size of the reference population, which makes genomic prediction for breeds with a relatively small population size challenging, such as Australian Red dairy cattle. Including other breeds in the reference population ...
Heritabilities for average mature weight were 0.47 for Herefords and 0.73 for Wokalups compared to values of 0.29 and 0.54, respectively, for mature weights treated as repeated records. Rate of maturing was moderately heritable in both breeds, heritability estimates being 0.32 and 0.33. Genetic ...
However, there were 2 genomic regions on chromosome 6 that validated in both breeds, including a cluster of 6 SNP at around 13.5 to 23.7 Mbp and another cluster of 5 SNP (70.4 to 75.6 Mbp). A third cluster validated in both breeds on chromosome 26 (0.33 to 1.46 Mbp). Validating SNP ...
