Performing Beef Cattle Genetics Tests

By Susan Dawson


When farmers raise cattle in order for these animals to be turned into meat later on, it is always very crucial for them to perform some beef cattle genetics tests. Now the main reason as to why these tests have to be performed to simply check whether the animal to be slaughtered would have some irregularities in it. That way, farmers will know which of their livestock will be healthy enough to be turned into consumable meat.

Now all cattle or cows will be subject to a series of tests that the farmers would be giving in order to know about the animal. The very first test that will be performed would be the qualitative test where in one would test mostly physical traits of the cow. One would test the cow for defects in areas like hair color, presence of horns, body shape and such.

If there is the qualitative test, then there also is the quantitative test which would now test the calculative traits of an average cow. Examples of these traits would be weight, fat, and certain nutrient counts in the body. Anything that can be measured in numbers will be tested here for any irregularities that do not seem right.

One of the most common ways to conduct tests would actually be through sampling of the DNA of the animal and test it for anything that may seem out of the ordinary. The good thing is that a lot of labs actually give farmers kits where in they would be able to test their animals. These kits are rather easy to use and will not take a long time to understand.



The simple way to test the cow or cattle would be through the simplest method of sampling which is the hair sampling. Basically, all one has to do is locate the hairs at the end of the tail of a cow and pull a few out. From there, one will be able to test the structure of the DNA using the sampling kit.

Now one would take note that when a cow is still very young, it will not have fully developed hair yet. In the situation, the more accurate but harder thing to do would be to get a blood sample instead and get some of the DNA from there. This can be done so that one will not need to do hair sampling.

Do take note that it is much harder to draw blood from an animal instead of plucking out a few hairs. One would still need to inject the needle into the body of the animal, and start drawing out the blood. Once that is done, the blood will be placed in a tube where it will be used for testing.

It is very important to make sure that the cattle is extremely healthy before it is turned into beef so that it does not carry any body disorders. By making sure that each cow goes through a beef cattle genetics test, it is possible to know which meat will be suitable to consume and which are not. From there, farmers will also have an easier time with their job.
