Find Out Helpful Information About Hybrid Vigor In Labordoodles

Various contentions have been put forward in the dog world by some, (eg those against mixed breeds), that ‘hybrid vigor’ is allegedly not possible (for example) when breeding labordoodles (ie mixed breeding of Labradors and Poodles) as it is alleged that hybrid vigor is only possible with mixed breeding of unrelated animals (eg horse and donkey). However, that it not correct.

For example, see labrodoodles are ‘intraspecific hybrids’ (ie are within species breeding) and do show hybrid vigor.

Also, see Dogs). And the same research has shown that the higher the rate of inbreeding (eg in purebreds), the lower or shorter the longevity or survival rates. This relates to the term known as ‘inbreeding depression’, and which is
described in more detail at inbreeding depression and inbreeding depression.

And this may be due to the benefits from hybrid vigour, especially compared to the negative effects known as ‘inbreeding depression’ present in purebreds.

Unlike some breeders, we can guarantee the genetics of the puppies are solely Labrador/Poodle, as the parents of our Labradoodle puppies are purebred, and with pedigree papers. And this also ensures that they are definitely F1 puppies.

The term ‘hybrid vigor’ is used in various fields, such as breeding livestock, rabbits, aquaculture, plants, cats, Dogs, etc.

And rather than just us giving you our opinion etc re hybrid vigor, we thought you may like to read information from other sources. So that you can make an informed choice or decision.

So, below are some relevant extracts re hybrid vigor, and links to their sources:

From MSN encarta online:

‘hy-brid vig-or

improved traits resulting from crossbreeding: the increased growth, disease resistance, or fertility seen in hybrid species.’

From Encylopedia Brittanica online:

‘Increase in such characteristics as size, growth rate, fertility, and yield of a hybrid organism over those of its parents.’

‘Plant and animal breeders exploit heterosis by mating two different purebred lines that have desirable traits. The first-generation offspring generally show, in greater measure, the desired characteristics of both parents. Since this vigour may decrease if the hybrids are actually mated together, the parental lines must be maintained and crossed for each new crop or group desired.’

From Merriam-Webster Online Dictionary:

‘heterosis

the marked vigor or capacity for growth often exhibited by crossbred animals or plants — called also hybrid vigor’

From report by CSIRO:

“The benefits of hybrid vigor only appear in crossbred animals that have parents of completely different breeds.”

From a transcript of the Senate:

“veterinarians recognize the concept of ‘hybrid vigor,’ especially in first generation hybrids”

From United States Department of Agriculture, University of Arkansas, and County Governments Cooperating:

“The highest level of hybrid vigor is obtained from F1’s, the first cross of unrelated populations.”

“Hybrid Vigor - An increase in the performance of crossbred animals over that of purebreds, also known as heterosis.”

So, there should be little (if any) doubt that the first generation (ie F1) Labradoodles have the maximum hybrid vigor and the least inbreeding depression compared to other generations etc.
