Can you breed registered cattle father to daughter, mother to
What are the do's and don'ts of breeding a bull to his daughter, mother, granddaughter, or sister? Mating any of the above would result in a high level of inbreeding. Generally speaking, inbreeding of this nature should be avoided.
The most obvious effects of inbreeding are poorer reproductive efficiency including higher mortality rates, lower growth rates and a higher frequency of hereditary abnormalities. This has been shown by numerous studies with cattle, horses, sheep, swine and laboratory animals.
I've been asked by several breeders if it is "OK to breed two half-siblings" (usually, a bull and a cow that share the same sire). The short answer is that there is nothing "wrong" with breeding any two animals of any degree of relatedness, as long as one realizes the potential risks and benefits of the mating.
Acceptable Levels of Inbreeding
Average inbreeding coefficient levels of less than 5pc within a breeding program are considered low, with inbreeding levels of 5–10pc generally considered more moderate levels of inbreeding and warranting more careful management.
The risk for passing down a genetic disease is much higher for siblings than first cousins. To be more specific, two siblings who have kids together have a higher chance of passing on a recessive disease to their kids.
You can avoid inbreeding if you utilize several breeding groups – if you know the parents of the cows. This is impossible, however, if cattle are bred on summer range where all cattle are pastured together. “At home, you can create separate breeding groups,” says Thomson.
Inbreeding decreases resistance and milk production in dairy cows. The negative aspects of inbreeding involve poor reproductive efficiency, high mortality rates, low growth rates, and a high frequency of hereditary abnormalities. Inbreeding leads to a reduction in genetic diversity.
Close inbreeding (breeding first and second-degree relatives), substantially increases the risk of genetic defects or inherited disorders and inbreeding depression and these occur at a faster rate, compared to inbreeding of less closely related individuals [3].
Each parent contributes 50% of the genetic make-up. But, if you mate a bull to its mother, 75% of the genetic make-up will be the same and the chance of the fault occurring simultaneously in both chains is very high. This is called in-breeding and must be avoided wherever and whenever possible.
Inbreeding does not create undesirable recessive genes, but it does tend to bring to light these unfavorable genetics. This leads to a decline in average phenotypic performance called inbreeding depression. This phenomenon is well documented in all the major livestock species.
Year-round breeding
Ewes may be bred when they are in poor body condition. The ram may breed his daughters and dam. Undersized ewe lambs may be bred.
You can have father-daughter matings in beef cattle, but it is not recommended. This type of breeding practice is called inbreeding or close breeding. Again, this breeding practice is rarely practiced today, although it was common in the foundation animals of most breeds.
steer, also called bullock, young neutered male cattle primarily raised for beef. In the terminology used to describe the sex and age of cattle, the male is first a bull calf and if left intact becomes a bull; if castrated he becomes a steer and about two or three years grows to an ox.
Puberty in bulls occurs when they can produce viable sperm. This happens at approximately 12 months of age, though it can vary in individual bulls several months before or after this age depending on biological type (primarily frame size and potential mature weight), nutrition, and health status.
The advantage of inbreeding in cattle are: - It guides in developing a pure line in any animal. - It can concentrate on the genes of a superior ancestor. - It can fix the desired type relatively quickly.
Introduction. Mating with relatives (inbreeding) can result in offspring with reduced survival and fertility, a phenomenon known as inbreeding depression [1]. Inbreeding depression has been observed to occur in wild animals with severe consequences [2,3].
Inbreeding increases the risk of recessive gene disorders
Inbreeding also increases the risk of disorders caused by recessive genes. These disorders can lead to calf abnormalities, miscarriages and stillbirths.
Inbreeding means mating father to daughter, mother to son, and brother to sister. Line breeding involves mating more-distantly related animals, although there is a conventional wisdom that says line breeding is whatever works and inbreeding is whatever doesn't.
They created the “50/500” rule, which suggested that a minimum population size of 50 was necessary to combat inbreeding and a minimum of 500 individuals was needed to reduce genetic drift. Management agencies tended to use the 50/500 rule under the assumption that it was applicable to species generally.
Dispersal: Many animals, especially males, leave their family group once they reach sexual maturity. By dispersing to new areas, they reduce the chance of mating with relatives. Some animals only breed during certain seasons, then separate again. This periodic dispersal helps diversify the gene pool.

DNA testing has revealed that a teenage brother and sister had a baby together in Northern Ireland. The little boy, who is now a toddler, was born in 2012 as a result of the siblings' incest. His mother was aged just 13 when she became pregnant, while his father – her older brother – was 15.
