Hi Josh,
Have you found any breeds to do particularly well on specific type of field? I'm curious if you've had the opportunity to experiment enough or research and determine specific breeds that do particularly well on a particular plant species indigenous to specific regions.
Everybody will be in different places and I would assume certain breeds perform better in varying regions, is this a correct assumption or has the domesticated cow been pretty well evened out on most U.S. regions?
There are definitely different breeds that do better or worse in different conditions. No the domesticated cow is NOT the same across all breeds - it goes well beyond physical appearance but includes everything from heat and/or cold tolerance, to parasite resistance, resistance to eye diseases in different conditions, vulnerability or resistance to
solar glare when there is no shade in the pasture. There is also differences in how readily different breeds browse on tree shrubs - all will do some browsing, but some breeds will go to great lengths to mow down a tree. Also there is differences in foot hardness - some of the breeds that originated in mountainous rocky regions have hard feet that grow back quite aggressively due to the wear they got from walking on rocks all the time - great if you have abrasive soils but not so good if your soils are really soft so that the fast growing toenails don't get worn off and begin to curl over and crack, which is painful for the cattle and means you need to spend extra time figuring out how to trim their hooves.
So
breed choice matters a lot, but at the same time I do believe that too much concern is made over breed at the expense of learning how to set up a
proper selection and culling program in your cattle herd. Regardless of what breed you choose, if you don't cull bad feet, sickly individuals, individuals with calving difficulties, individuals with parasite issues, and so on, then the advantageous characteristics of the breed will be completely overshadowed by the genetic problems cropping up in the cattle herd - which are then often unfairly blamed on the breed rather than being attributed to bad management practices. It's always easier to point elsewhere than at oneself javascript:emoticon(':)');
Does your experience bring you to agree with Joel Salatin's opinion of sterility dropping the farther from pure bred you get?
I am not aware of this phenomenon. I feel that the biggest variations in fertility are because of the selection and culling practices of individual farmers - which all boils down to herd management. There are fantastic and there are awful breeders regardless of whether the animal is purebred or crossbred. Is the breeder picking animals based on fertility and maintenance characteristics, or because of the appearance or single trait selection, or because they have a particular attachment to the animal? Price, cuteness, pedigree, show-ring ribbons, or a love for "Daisy" because she was bottle raised are all NOT the right reasons for picking an individual heifer or bull calf for your breeding herd. Breeders - regardless of whether they are commercial or hobby farmers, purebred or crossbred - need to understand this, those that do generally produce good cattle, those that don't won't. Most bad genetics are not produced by bad people, just people who have learned to focus on the wrong traits or have poor genetic selection and culling habits, despite the very best of intentions. In the end, the responsibility rests with the cattle buyer, not the cattle seller, to be very clear about what they are looking for for their herd and how to recognize the genetic traits that will reveal low maintenance and high fertility, and not passing that responsibility to the salesman.
He says he likes a pure bred bull and a specific mixture for the rest of his stock.
A lot of commercial beef producers like this strategy because it gives them more control over the genetic mixture of their cattle herd, which in turn gives them greater predictability over the size and growth rates, and consequently the finishing times required when raising their cattle. When a beef marketing program depends on having cattle finished by a certain date and then one year 30% of the herd needs an extra 3 months time to finish because these crossbred cattle happened to have a larger frame size, that has devastating consequences to the marking program and can lead to feed shortages if the animals don't head to the butcher by the anticipated date. The only way to have consistency in frame size (and thus the time it takes to finish for slaughter) is to use purebred, or a terminal crossbreeding program. The greater the difference between breeds, the greater the unpredictability.
As an example, let's say you breed Angus. You can pretty much expect all your calves to finish around 1060 lbs (+ or -), and with the right grazing program this could occur in as little as 16-18 months. A terminal cross between an Angus and a Galloway (which is a very similar sized breed) would likely produce a similar sized animal, but a terminal cross between an Angus and a Simmental (which finish several months an around 320 lbs heavier) will produce something in between. So far, as long as only the terminal cross from two pure-bred parents is used, the results are still predictable.
But now imagine rebreeding the crossbred Simmental-Angus heifer to an Angus bull, or a Simmental-Angus crossbred bull. Now the genetic mix is no longer predictable - the calves born can be anywhere on the spectrum - some will display predominantly Angus characteristics, some will display predominantly Simmental characteristics, and the rest will be anywhere along the scale. Consequently, as a beef producer, it becomes impossible to predict at what age and size your calves will finish - it will vary from year to year and every calf will need to be assessed individually. That's why cross-bred programs become more difficult to manage for smaller-scale producers. When an operation has thousands of cattle, like the feedlots, they can afford to sort the cattle by frame size as they come in. They will even buy calves based on their frame size in order to keep a steady supply of cattle finishing on the date required for their marketing program. Smaller-scale producers don't have this luxury and are therefore better off with a purebred or a terminal-cross cattle herd if they are looking for predictable results for their grass-finishing program. The
Genetics and Breeding: Selecting the Right Animals for Your Herd chapter of my book goes into this topic in detail, including learning how to structure your selection process and what characteristics to look for in both bulls and heifers/cows when putting together your breeding herd.
