Farming is no 9 to 5 job. We don't work "regular hours", and we certainly aren't afforded the luxury of planning every facet of our days. Sometimes its a stretch for me with my "real job" as an agriculture teacher to remember this. I can write my lesson plans, get my materials for class together, and control much of what happens inside the confines of my classroom, but back on the farm this isn't always the case. We can't control when a heifer is going to have her first calf, sure we can breed her to calve within a particular time frame, but we can't prevent her from having it at mid-night on the coldest night of the year. Sure we can maintain our fences and keep them in good condition, but we can only be reactive when the neighbors' son who is learning to drive loses control of his pickup and plows through our fence. With so much of farming being reactive, we make an attempt to control as much of it as we can, or at least plan for things.
One thing that we do on our cattle farm is take proactive measures to keep our cattle healthy. The number one way that we do this is through prevention. Each spring and fall we "work" our cattle. On our operation, working cattle means bringing them in from their pastures and administering vaccinations, applying wormer, ear-tagging and tattooing for animal identification, castrating bull calves, monitoring weights, and updating herd records. These practices help keep our animals healthy and provide consumers with safe and nutritious beef.
We vaccination cattle with both killed and modified live vaccines. A vaccine is a medicine that gives our cattle immunity to certain diseases. In the killed form the vaccine is often made from weakened or killed forms of the
microbe, its toxins or one of its surface proteins. The agent stimulates
the animal's immune system to recognize the agent as foreign, destroy it, and "remember" it, so
that the immune system can more easily recognize and destroy any of
these microorganisms that it later encounters. This way if the disease does present itself later, the animal's body will have seen it before and know what to do and how to destroy it. In the modified live form the vaccine is manufactured from a modified version of the virus that is still alive. It works much the same way as the killed vaccine in how the body responds. When administering these vaccinations we must take care not to mix the syringes that contain the vaccines. If killed and modified live vaccines end up in the same syringe they will become denatured and ineffective when administered to the animal. We give both killed and modified live versions because vaccinations to certain diseases are only available in one or the other form. When we administer these vaccines we follow
Beef Quality Assurance, or BQA, guidelines for animal health. Beef Quality Assurance is a national program that provides guidelines for all aspects of the beef industry, including animal health. It helps build consumer confidence in beef through communication of common goals and guidelines between beef producers. Under the Animal Health umbrella, BQA states that all products labeled for intra-muscular (IM) use should be given in injection site triangle in the neck region of the animal.

Products with low dosage rates are recommended, and no more than 10 cc should be given in any one injection. Our cattle receive vaccinations against 3 different respiratory diseases,
Bovine Viral Diarrhea or BVD and the 5 serotypes of
Leptospirosis. All of these vaccinations are contained in vaccination called
Triangle 10. We also give cattle a vaccination called
Alpha-7 which protects them against several bacterial diseases including
blackleg. The third and final vaccination our cattle get protects them from
Pinkeye.

In addition to the vaccinations our cattle receive, they also get wormer. This helps to prevent internal parasites that they can pick up while grazing in the pasture. Cattle commonly pick up internal parasites, or worms, when soil temperatures rise above 55 degrees F and grass is wet either from dew or rain. These create conditions where the worms can thrive. On our farm we use a topical wormer that is poured down the back of the cattle, from there it is absorbed into the body. We change worming products every other year to prevent parasites from developing a resistance to the product. Wormers alone cannot control parasites, good pasture management is also key, but that'll have to be a topic for another day.

| The 4th calf born in 2010 |
Each purebred cow on our farm has a specific identification. This identification comes in the from of an ear tag. Animals are ear tagged within the first few days after birth. This practice helps us identify individual animals and facilitates accurate herd records. The ear tags are made from heavy duty, flexible plastic and we write each animal's identification number on them with a special marker. Like most producers we have a method to assigning ear tag numbers. Our system works like this...The first digit in the tag number is the birth year and the rest of the digits are the animal number born in that year, for example: 201 is the first calf born in 2012, 202 is the second calf born in 2012, 203 is the third calf born in 2012, so on and so forth. We recently acquired two Polled Hereford heifers and one of them calved earlier this spring.

| Applying a tattoo to a bull calf's ear |
The identification system works a little different on the white-faced cattle on our farm. The Polled Hereford system is the last digit is the birth year and the first digit is the calf number, so 12 is the first calf born in 2012, 22 is the second calf born in 2012, 32 is the third calf born int 2012, so on and so forth. I'm sure it seems kinda crazy, but there is a method to our madness. These systems help us keep track of the individual animals and monitor their growth and performance.Animals also receive a permanent identification in the form of a tattoo in their ears. We have a special pair of pliers that hold the character needles in the shape of numbers and letters. The cattle receive their tag number tattooed in their left ear and a breeder code specific to our farm in their right ear. To apply the tattoo first we have to clean their ear, we then roll on the tattoo ink, next we use the pliers loaded with character needles to pierce the ear and imbed the ink, and lastly we wipe away any excess ink from their ear.
Male calves that will not be sold as bulls are castrated. We remove the testicles, or castrate, these animals for a number of reasons. Including:
- Higher Quality Meat - Intact bulls produce more hormones, including testosterone, that will taint the taste of their meat
- More Weight Gain - Castrated bulls, or Steers, put all the energy they receive from consuming food toward gaining weight
- Easier to Handle - Steers are much calmer and easier to work with than bulls. This makes it much safer for farm personal
- Prevention of Unwanted Pregnancies - It seems like intact bulls always find a way to get in with the heifers, no matter how strong the fence. Castration helps prevent unwanted pregnancies in the cow herd, and ensures that only the genetically superior males reproduce
There are several ways to go about castrating bulls. We can cut them, band them, or emasculate them. We bulls are cut the scrotum is sliced, the testicles are pulled out, the blood vessels and other connective tissues are severed, and the testicles are removed. This sounds like the most gruesome method, but it is actually the most humane for the animal because the process is very fast and they recover quickly. When bulls are banded a special rubber band is placed around the scrotum between the testicles and the animal's body. This band cuts off blood flow to the testicles and the will shrivel and fall off. This method should only be used on young animals, less than two months of age. In emasculation, a special tool called a emasculator is used to crush the spermatic cord connecting the testicles to the rest of the reproductive tract. Cattle producers must evaluate which method works best for them and employ it in their operation. In our operation, we use a combination of banding and cutting depending on the age and size of each individual animal.
We monitor the weights of our animals. We record their birth weight, weaning weight, and yearling weight. This is done to track their growth and can be used as a predictor of the performance of an animal's offspring's performance as well.
It is essential that we keep accurate records. Some producers use elaborate computer programs to track their cattle, I prefer a spiral notebook and pencil, but whatever the method they must be accurate.
Hope you have enjoyed this peak inside our cattle operation and learning about what we do when we work cattle. We work hard to keep our animals health and provide consumers with safe, nutritious, and healthy beef. Please comment with any questions or comments, we'd love to hear from you.
