POLLED SIMMENTAL FLECKVIEH CATTLE

POLLEDNESS IS A VALUABLE TRAIT

This is why we prefer polled simmental fleckvieh cattle

Polled simmental fleckvieh cattle become more and more common in many countries.

Horns no longer fit into many modern stall housing systems, for example due to use of suppressor grids.

There is also some outdoor equipment that is not suitable for animals with horns, for example mineral feed dispensers.

Polledness is a functional trait that increases the value of the animal and improves its well-being on a daily basis.

Unless the animal is anaesthetised, polling is painful. It causes stress and weight loss and makes the animal more susceptible to a variety of infections. And polling incurs additional expense in terms of equipment, vets’ bills and labour.

An ever increasing number of countries are introducing animal welfare regulations, stipulating the way in which vets, or livestock owners themselves, should poll animals.

We expect these regulations to be tightened, both nationally and internationally.

 

How to breed polled cattle

At Fedal Simmental, we aim for heterozygous and, in particular, homozygous polled simmental fleckvieh cattle.

Due to the advantages of polledness, numbers of genetically polled cattle are on the increase in commercial herds.

There is a global trend to eliminate horns in cattle by crossing them with polled genes.

The gene for polledness is a single dominant gene, and the gene for horns is a single recessive gene.

Since the polled gene is dominant over the horned gene, it is relatively easy to breed polled simmental fleckvieh cattle.

1)
A heterozygous polled bull (P) is mated with a cow with a predisposition for horns = 50% heterozygous polled progeny (P) and 50% progeny with a predisposition for horns.

2)
A homozygous polled bull (PP) is mated with a cow with a predisposition for horns = 100% heterozygous polled progeny (P).

3)
A homozygous polled bull (PP) is mated with a heterozygous polled cow (P) = 50% homozygous polled progeny (PP) and 50% heterozygous polled progeny (P).

4)
A heterozygous polled bull (P) is mated with a heterozygous polled cow (P) = 25% homozygous polled progeny (PP), 50% heterozygous polled progeny (P) and 25% progeny with a predisposition for horns.

5)
A homozygous polled bull (PP) is mated with a homozygous polled cow (PP) = 100% polled progeny with 100% homozygous polled progeny (PP).
