Greetings from a "Bull Session virgin." I would like to throw out a scenario for you all to think about. A guy has a straight bred angus herd and has been that way for years. The guy reads every beef magazine that tells him he is stupid for not crossbreeding. He has tried some breeds in the past, but he never likes the results and always goes back to angus. He is knows that fertility is extremely important to the cattleman and is concerned when young cows in good condition come up empty. This same guy wants to experiment again, but wants to stay with an English black polled breed and is willing to try AIing some heifers if he can find a proven calving ease sire. He is considering South Devon and Irish Blacks. Is an F1 that beneficial for fertility and longevity or is he barking up the wrong tree?
No, my friend, you are NOT barking up the wrong tree! There are many factual statistics concerning the benefits of "crossbreeding" and the results derived from the F1 calves, both in the feedlot and in keeping the heifers as replacements. Go to the Internet by way of "Dogpile" or "Google" and type in the "SEARCH" box "Crossbreeding of Beef Cattle". That will educate you and your "guy" thoroughly on the benefits of crossbreeding!
Now, having said that, let's consider some proven facts and think about the real life side to cattle breeding and crossbreeding. As all experienced breeders know, the old statement that "Like Begets Like" is very true. If you breed a proven bull (of ANY breed) who has a majority of acceptable traits and characteristics and phenotype to cows with the same TYPE of genetics ( notice I did NOT say that it had to be the same breed as the bull), you have a much greater chance of having successful calves, either in the breeding paddock or feedlot, than if the cows are scrubs, and/or genetically worthless.
Purebred cattle of any breed are more capable of reproducing their good characteristics than cattle which have been bred in a helter-skelter manner with the breeder paying no attention to desirable traits in the respective matings. If one breeds scrubs to scrubs - the result is scrubs.
Crossbreeding on the other hand is NOT breeding scrubs to scrubs, even though some people are under the wrong impression concerning CORRECT crossbreeding. The "Heterosis", or crossbred vigor derived from mating two different breeds together, results in improved characteristics of the resulting calves
IF, and this is the operative phrase in crossbreeding, IF the genetics, characteristics, traits, and phenotype of the two mated individuals are optimal for generally accepted HIGH QUALITY beef production - not JUST because they are of two different breeds.
If I were advising "Your GUY" with the 'straight-bred' Angus herd that has been that way for years - - (which doesn't mean that the cattle are good, bad, or high quality or low quality) I would suggest that he has his "breeding cow herd" analyzed and culled, if necessary, by a cattleman or cattlemen, and carefully plan what his ultimate goal for his herd will be, either as a cow-calf producing operation, or as a feedlot supplier, and THEN look for a bull answering those requirements.
The genetic traits and phenotypes in comparing South Devon and Irish Blacks are similar in some instances, and quite different in others. Having done an in-depth study and examination of the Irish Blacks recently, I wholeheartedly recommend the Irish Blacks as the optimal crossbreeding breed for "your GUY'S" herd of Angus straight-breds. I know what the Irish Blacks genetics can do for that type of beef herd, and I am not that familiar with the South Devons, so I can't speak to that mating, other than to say that the South Devon is more closely aligned to a 'multi-purpose' type breed and higher milk production and dairy characteristics will present themselves in future matings.
Click on the "IRISH BLACKS" thumbnail ad at the right side of the CattleToday and Ranchers.net front pages and carefully read ALL of the website. I think that you might be surprised. And tell "your guy" to check out the website also!
