COAT COLOUR INHERITANCE IN BEEF CATTLE

THERE ARE A NUMBER OF SETS OF GENES THAT DETERMINE COAT COLOUR IN CATTLE

THE MOST COMMON SETS ARE:

• Basic coat colour

• Dilution of basic colour

• Inhibitor (ie. Charolais)

• Solid Pattern

• White Face

• Spotted

THERE ARE SIX POSSIBLE COMBINATIONS OF BASIC COAT COLOUR:

RbRb

RbR

RR

Animal is Black (or Grey) Homozygous Black

Animal is Black (or Grey)

Animal is Red

Rr Animal is White

Rbr

Animal is Black or Grey Roan

Rr Animal is Red Roan

Heterozygous Black, Heterozygous Red

Homozygous Red

Homozygous White

Heterozygous Black, Heterozygous White

Heterozygous Red, Heterozygous White

EACH ANIMAL CARRIES TWO COPIES OF THE DILUTION GENE

Homozygous for dilution and the animal will be Diluted in colour. Dilutes Black to Grey and Dilutes Dark Red to light red or yellow

Recessive and Homozygous non-dilution. The animal will not be diluted. Does not dilute black or red colour.

Heterozygous for dilution. The animal will be diluted in colour.

THERE ARE THREE FORMS OF THE GENE THAT CONTROL COAT COLOUR Rb

Black Gene

Red Gene

White Gene

Every Animal carries two genes for basic coat colour. An animal homozygous for that gene will breed true and can only pass that type onto his progeny such as RbRb Homozygous for Black

DILUTION GENE

Dilution Gene

Dominates causing coat colour to be diluted

Non-Dilution Gene

Recessive form of gene. Does not dilute coat colour

Perform first TAI 66 ± 2 hr after PG in estrous cows. Second TAI with GnRH only in non-estrous cows.

Time for Fixed-time AI (TAI) should be considered as the approximate average time of insemination based on the number of females to inseminate, labor, and facilities.
