The coat colour of animals is playing a role in marketing in the Australian beef industry.
Colour is not associated with meat eating quality but Webb Black Simmentals are well aware of industry drivers, and ask clients to consider the following options when selecting a bull.
- Homozygous black bulls with a black coat
These bulls have two black genes, in general and discounting other genetic complications such as the diluter gene, all the calves of a homozygous black bull will be predominantly black, regardless of the colour of your cows.
This is because the black gene is dominant. If you insist on black calves with no exceptions, a homozygous black bull would be your choice.
- Heterozygous black bulls with a black coat
These bulls have one black gene and one red gene. A large proportion of their calves will be black. As the red gene is recessive, his calves cannot be red unless the mother also carries a red gene.
Generally, if a heterozygous black bull is crossed with:
- Homozygous black cows then 100 per cent of calves will be black.
- Heterozygous black cows on average 75 per cent will be black.
- Homozygous red cows – on average 50 per cent of these calves will be black and 50 per cent will be red.
- Black cows that are a mixture of homozygous and heterozygous – the calves will average between 75 and 100 per cent black.
