Some Reflections on Fall Meetings and Crossbreeding

Joe C. Paschal

I missed the opportunity to include my thoughts last month in The Ear and I regret it. September through November are busy months for me as there are many Extension educational programs in the 37 counties in South Texas I am responsible for plus several others. Some of these educational programs have a long history going back to the early 70’s and even in the 60’s. In addition I had the opportunity to speak at three “eared” breed associations educational programs at their national meetings (this in addition to my regular duties and of course the ranch where we began calving in mid-October). This month I’ll cover some of the things I picked up at these meetings and then wrap up with some comments on a white paper currently making the rounds about crossbreeding.

In many of these meetings the most often discussed topic was about the ongoing drought and whether or not some rebuilding of the cowherd should occur if rain had fallen and pastures were returning to normal. I was “googling” some drought information and came across numerous NBC affiliate stations up in the Illinois area with a video clip about a farmer named Ken Wiseman in Golconda, Illinois who had been raising Angus until a few years ago when he decided that he would switch to Brangus and breed his Angus Cows to Brahman bulls. In his own words: “The Brangus cows that we have, they will stay out on top of the hill in the hot sun and keep eating. The others go to the shade or to the pond,” Wiseman said. “The breed,” he said, “developed a natural tolerance to heat and drought. If they’re out eating, they’re putting on weight and that’s money in the farmer’s pocket.” Wiseman said the hardier animals “are engineered to survive – and even thrive – in this weather.” You can’t pay for an ad like that even if it is in Illinois! I emailed it to Dr. Joe Massey, Executive Vice President at International Brangus Breeders Association, tweeted it on my Twitter account (#Joe_Paschal) and was immediately picked up by Certified Angus Beef. I guess they wanted to know what I was up to!

Mr. John Ford, the Executive Vice President of Santa Gertrudis Breeders International held a Mexican Cattlemen’s Field Day in Kingsville, Texas to present new data to potential buyers of Santa Gertrudis cattle on the maternal ability of the Santa Gertrudis cow and the potential of Santa Gertrudis and Santa Gertrudis cross feeder calves. John had really done his work; he had current data from various sources that indicated the current level of performance and particularly the performance of Santa Gertrudis crosses, both maternally, in the feedyard and as carcasses. I reviewed the Texas A&M Ranch to Rail Program that we conducted from 1991 until 2005 and presented feedyard, carcass and financial performance of percentage Bos indicus crosses and specifically Santa Gertrudis steers, including some tenderness data. John had a large international as well as a domestic group of breeders and the meeting was very successful.

In mid October I was asked by Dr. Tommy Perkins, Executive Vice President of Beefmaster Breeders United, to speak and judge at their National Beefmaster Convention in Branson, Missouri. Tommy had a terrific crowd at his “Meet in the Middle” meeting and in addition to working I got a chance to ride (and drive) one of the DUKWs that we toured on one afternoon. During World War II these were used to ferry troops from the ships in the invasion forces to the beachhead and then onto land. The top speed in the water was about 5 mph and the bottom and sides were made of pretty thin metal that might stop a BB pellet. My hat is off to anyone who rode them in under fire but that day it was strictly for fun! But I digress. Tommy had set up an excellent educational program to discuss ways to prevent cattle theft (seems to be a big problem in every state!) and I gave a talk on animal ID methods and we demonstrated freeze branding to a large crowd of folks! One thing that impressed me was that the quality of the cattle and the locations of the cattle in the Open and Junior Beefmaster Shows. There was a significant contingent of good cattle from Missouri, Oklahoma, Kansas, Arkansas and more northern climates as well as Texas and other warmer states.

Recently I had the opportunity to speak at the American Brahman Breeders Association 2nd Annual Membership Convention in Galveston, Texas. Mr. Chris Shivers, the Executive Director of ABBA had asked me to talk on “Understanding the End Product” and with a little help from my colleague Dr. Dan Hale (Texas A&M AgriLife Extension Meats Specialist in College Station, Texas) I put together a credible presentation using Brahman cross steers and showing how the value of a carcass is determined and what detracts from its value. Since I also assist with the ABBA’s Carcass Project where straightbred Brahman steers consigned to the program are fed at Grahman Feedyard in Gonzales, Texas and processed at Sam Kane Beef Processor in Corpus Christi, Texas I pointed out how straightbred Brahman steers fit. It might surprise you but most of these straightbred Brahman steers will fit mainstream fed beef supplies very well, mostly very high yielding (YG 2) USDA Select carcasses. Chris did discuss the ABBA F1 Certification Program. The program, begun in 1979 by then Executive Director Wendell Schronk, promoted the use of an already widely recognized and highly regarded F1 female and has seen resurgence in interest and applications for both the Certified and Golden Certified F1 Female Programs.

The idea of marketing the crossbred females of the Eared breeds may have begun with the ABBA F1 Female Program but it is certainly not new and it has been adopted by several breeds and not all of them would classify as “eared breeds”. The International Brangus Breeders Association has their “Brangus Gold” Program, BBU has their “E6” Program (which can include up to full blood Beefmaster females) and SGBI has their “Star 5” Program (which can include progeny from registered and nonregistered parents).  There is even a program begun by a NON-EARED breed to emphasize the importance of crossing it with Eared breeds to ensure a high level of productivity in more tropical climates, the Southern Balancer Program promoted by the American Gelbvieh Association. The Southern Balancer must be at least 25% Gelbvieh and can be anywhere from 6.25 to 50% Bos indicus (depending on how much you need for your environment or how much hybrid vigor you want or need to make a profit!). I am sure that there are other programs in other breeds that highlight the F1 female, especially if produced by sires or out of dams of a particular breed since the greatest benefit of the F1 is that it exhibits 100% hybrid vigor or heterosis for EVERYTHING – from the cradle to the grave – which brings me to my last topic.

A few months ago a white paper written by Dr. Nevil C. Speer, an agricultural economist from Western Kentucky University, entitled “Crossbreeding: Considerations and Alternatives in an Evolving Market”. This paper, supported (paid for) by Certified Angus Beef, LLC, made the rounds of the popular press and was either praised or cussed. I have never met Dr. Speer but I have read a lot of his stuff in many different venues and he is a logical thinker even if this is a “bought and paid for article” (some might consider mine in the same vein).  You can access the full article here: http://www.cabpartners.com/news/research/CROSSBREEDING_WHITE_PAPER_2.pdf

I encourage you to read it and especially the last graphic (Figure 5: Crossbreeding Decision Maker) where he makes four important points in evaluating whether or not a crossbreeding system is useful or beneficial. First is has to be easily conducted. Second you must have readily available superior bulls for a terminal cross. Third it won’t cause you to lose money due to loss of herd size, type of cross or uniformity. And fourth, it will improve maternal performance (or not impact functional traits). If these four criteria are met then crossbreeding proves beneficial. I agree!

Importance of Records, Individual Selection and Breed Choices in Crossbreeding Systems

Joe C. Paschal

Last month I ended my article with some comments on whether or not crossbreeding was still economically relevant in today’s beef market based on an article written by Dr. Nevil C. Speer of Western Kentucky University. One interpretation was that it is not, that in today’s value based marketing system (read by some as “marbling score driven”), the value of carcasses with high marbling scores somehow outweighs the overall increase in lifelong performance of crossbred cows and their crossbred fed offspring. I doubt that that is case but still crossbreeding is not free. There is a cost to produce the purebreds that form the basis of the cross but this cost is usually passed on to the producer who purchases these females. If both male and female crosses are equally desirable as feeders or replacement females then the additional cost can be recouped equally. If there is a significant discrimination between the crosses based on gender then the more favorable gender will have to pick up more of the cost of production.

A well known example is the production of British x Brahman F1 steers and heifers. The steers will bring a lower price per pound than some other crosses (but less so today than a few years ago) but the heifers will command a premium as replacements. Discounts for crossbred bulls and steers depend on the demand for specific types. In the early years of the Brangus breed a good 3/4 Brahman x 1/4 Angus bull could be worth quite a bit of money to a breeder with Angus cows wanting to produce Brangus cows. On the Gulf Coast of the US there are places where 1/2 and sometimes 3/4 Brahman bulls are very useful, but these represent only a small fraction of the beef cattle produced in the US, but you get my point.

Most of the advantages that are pointed out in different crossbreeding systems come from the increased productivity of the crossbred cow, mainly attributed to heterosis. In animal breeding we define heterosis or hybrid vigor as the difference in level of performance in a trait when comparing the crossbred offspring to the average of the parents. There are parental breeds that are high performing in one trait or another (adaptation, growth, longevity, etc) but no breeds that I know of excel in ALL traits. This is why selection of breeds and individuals within breeds to make the cross is very important. It is equally as important as selection of individuals in a straightbred or purebred herd. In most discussions of why crossbreeding and hybrid vigor is beneficial (or is not) to commercial producers, the selection of breeds (and what they bring as “breed effects” to the cross) and the importance of individual selection are often glossed over or ignored in the larger discussion. I am not going to discuss breeds here, I think most of us have a good understanding of what different breeds have to offer, either as purebreds with some Ear influence (or not) or in a crossbreeding program with Ear influence (or not).

The purpose of selection is to increase, reduce or to maintain performance of the traits that you as a breeder or a producer have an interest. These traits may increase your income, reduce your costs or just lower your stress. These traits may be relatively easy to select for (or against) or not depending on the heritability of the traits, the amount of variation in the breeds being used, and the source and quality (accuracy) of the records that are available. The more information that you can bring to bear on your selection decision, the more likely your breeding or crossbreeding program will be successful. There are a number of efforts underway in the different Eared breed associations to encourage their members to increase the quantity AND quality of the production records that are being collected and reported to them. In this age of genomics and genetic markers we tend to forget that these are not “silver bullets” but aids to selection. The use of these new tools will improve the prediction of an animal’s genetic value, more so for young animals without progeny records. In the future these genomic tools will account for more genetic variation of these traits and others of significant interest (such as longevity, reproduction and health) but right now their best use is to improve the accuracy of the EPDs for animals with no (or few) offspring. It might change their EPD for the trait but the greatest impact will be on the accuracy or reliability of their EPD. The problem is that many of the genetic tests are for carcass merit traits, not for traits earlier in life affecting productivity and economics at the cow calf level.

Now, as in the past, the Eared breeds and their breeders have quickly and roundly embraced new programs and technology. They were among the first to utilize (and continue to do so) ultrasound for carcass merit, to participate in feedyard and carcass merit (including tenderness) data collection programs, and the use of genetic markers and other genomic tools. But these technologies should be used IN ADDITION TO the time consuming and less cutting edge documentation and reporting of calving, weaning and yearling data on all animals in your herd. I am familiar with the concept and the drudgery of record keeping and reporting but it is very important to collect to ensure that the accuracy of your animal’s actual and adjusted within-herd performance records and your breed’s genetic predictions or EPDs.

Eared cattle breeds are raised in a wide range of environments (not just climatic conditions) which affects their performance. If complete records are not collected, this nongenetic environmental influence may not be completely accounted for in genetic evaluations. In addition, there can be considerable “selection bias” injected into the records as only the records of the more/most desirable animals are sent. This bias tends to affect bulls more than heifers since fewer bulls are kept and registered. Selection bias will make the remaining animals look better than they really are because the lower performing (or less desirable) animals have been culled and their performance records were not collected. We all spend a lot of time and money breeding and raising good cattle for our customers, feeder cattle as well as replacements, and we need to collect and report as much data as we can, sometimes even if it is a little onerous. Just do it!
