Breeding bull to daughters

Help Support CattleToday:

After many years of study and probably a lot of bad results. Inbreeding and line breeding is a gamble, sometimes with some pretty bad consequences. It can be done and done well... but most people that do it only think they have good results... because they don't really know what results they have. And even the most informed make mistakes.

He may get father x daughter cows that way too. LOL

@Pineywoods230
Let us know what you do and what you get. Good luck.
He may be purchasing inbred animals WITHOUT PROBLEMS, but when he breeds them to his unrelated animals, the offspring WILL NOT be inbred, so his is about as safe as he can be in terms of acquiring unrelated animals to his for breeding purposes.

Sorry, but I don't see how that follows. The entire problem with inbreeding is using two animals with a specific genetic anomaly that when both parents carry the anomaly it is expressed. In inbreeding this can be different degrees of expression, and sometimes even 100% of offspring show the effects. (That does not mean the anomaly is visible.) If a carrier is bred to an unrelated animal they still pass the anomaly on as much as 100% of the time.

Bear in mind I said without problems. My take on @Ridgetop's comment (and he was saying it in jest) was that in an attempt to gat unrelated animals (from the sale barn) the animals that may be purchased/are acquired from the sale barn are themselves inbred. These inbred animals then become the parents of the offspring that are the animals that are targeted to not be inbred. My point was that if either parent of an intended offspring is inbred (or both of them) was that the resulting offspring, that is attempted to not be inbred, would indeed NOT be inbred, having received only 1 chromosome from each parent which results in none of the paired chromosomes in the offspring being from the same source, which is essentially what being inbred is. So, the offspring are therefore not inbred.

This kinda goes back to another discussion on another thread from not too long ago. That was, how far back/ how many generations do you go to not be considered inbred? The general consensus is 6 generations. If you don't have this generation limit, you could conceivably argue that every single species of life on earth is 100% inbred as every species can trace its linage back, if you go far enough, to a single individual. But let's stick to 6 generations.

So, can you have 2 'unrelated' animals that each have the same recessive gene anomaly and end up with progeny that have a problem because they end up homozygous for this trait carried in the recessive gene? Answer: yes.
 
It is a little different with horses. Inbreeding is sire to daughter, son to dam, or full siblings. LIne breeding is breeding grandsons and daughters to grand sons or daughters. When you see the same sire appear on the top and bottom of the papers, we call it line breeding. This can still concentrate recessive bad traits, Line bred Poco Bueno horses have a better chance of having HERDA. Line bred Imprsseive horses stand a better chance of being HYPP positive. For most commercial producers, you will be a lot better off to not breed your bull to his daughters.
Wow I haven't heard that name in years. Poco Bueno was basically the start of Appaloosa cutting horses in the 70's. Believe he was dead before that but his name was tied into almost every top performer. We had several geldings in that line and while we didn't cut they were sure top roping horses for us.

Poco can be found in the pedigrees of most cutting bred horses,. due to his 2 grandsons, Dry Doc and Doc O'lena. What happened to Poco Lena is one of the greatest tragedies in QH history. I still cringe when I think of it.

Yeah, you're crossing lines when you had dock bar and Poco in the same bloodline. That little runt dock bar was one hell of a horse also

It is very simple genetics . The more inbred they are the more the recessive genes are expressed in the phenotype.
Way easier to find any defective genes and eliminate them from the genetic population,instead of continual outcrossing and having a genetic defect carried in a huge percentage of the population before it is identified.
Take two line breed animals that are unrelated to each other and the offspring would have a huge amount of hybrid vigor.

He was bred to be a race horse, but he couldn't run, so they pulled him off the tracks. He was then shown halter, and won 9 grand championships. But his claim to fame, is as one of the top 5 cutting horse sires of all time. As far as I know, he himself never cut a cow. But his get sure could!
