Due to a large amount of criticism and misrepresentation of the facts, many people have expressed mixed ideas about the use of antibiotics and hormones for feedlot cattle farming and ranching. I have spent a large portion of my life getting well-acquainted with all stages of raising beef cattle and have a few thoughts and opinions to share.
Recently, I have started a series of posts describing my experience with feedlot cattle and am addressing your concerns about feedlot cattle, what they eat, if feeding corn harms them, and how feedlots impact the environment.
Today, I will address more about what these cattle are fed and how they are handled, using my experience as a guide.
Are feedlot cattle given feed additives?
Nutrients are often added to the feedlot cattle ration in micro amounts to provide a balanced diet- often referred to as feed additives. These additives often include vitamins and minerals required to balance the animal’s diet.
Other feed additives are used to enhance growth and promote health. The growth enhancers act at the cellular level to promote efficiency by partitioning energy to muscle tissue growth rather than deposition of fat. The health promoters work by improving efficiency of rumen microbes that digest the feeds and promote a healthy digestive tract. These are not similar to antibiotics used in human populations and do not necessarily act as materials working on the immune system.
These additives are used to make more efficient use of energy from feeds and are completely metabolized in the animal’s digestive tract, leaving no residues in the meat products. If residues were found, the product would not be allowed in the food system.
How often are cattle given antibiotics in a feedlot?
Cattle are treated for sickness no matter the stage of production or type of farm – conventional, organic, or natural. Cattle in feedlots are looked after on a daily basis. Each and every day someone rides through the pens and looks at each animal individually. Animals that show signs of sickness (usually respiratory) were brought to the veterinary hospital where a rectal temperature was taken. If the animal had a high temperature or showed significant signs of illness, they were given antibiotics as prescribed by the veterinarians protocols.
Sometimes entire groups of animals are given a treatment with antibiotics or other medicines. When cattle entering the feedlot are known to be stressed, have weakened immune systems, come from a mixed background like an auction barn, or other factors that may cause them to become ill, they are considered high-risk.
These cattle would be handled delicately when arriving at the feedlot. They would transition to higher-energy feeds slower and receive more forage. If 10% or more of the cattle became sick within a week, they were considered for treatment for the entire group. This often heads off any major sickness, and actually reduces the amount of sickness and antibiotics that must be given later on.
Janeal Yancey, meat scientist and mom from Arkansas, has addressed these concerns about antibiotics and residues in the meat supply. Be sure to stop by her blog and send her a message for more information on the topics.
Are feedlot cattle given hormones?
Feedlot cattle are often given a hormone implant to promote feed efficiency. These are synthetic hormones of the same chemical structure and are of minimal amounts when compared to naturally produced hormones already in the animal’s body.
The implants are given in a pellet form, inserted under the skin in the ear so there is no concern for muscle tissue damage or residues. They promote efficiency on the cellular level by promoting lean muscle growth and less fat deposition.
Despite consumer concerns over the use of hormones, there is no threat to meat safety. Hormone implant use has decreased over the last few years and has become more precise in timing and utilization. Nebraska cattle feeder and foodie, discusses hormones and how they are used in her feedlot cattle on her blog.
More questions about raising cattle
After listening to the concerns and question from many folks, I realize modern food production can be a scary thing. I have spent a large amount of time studying subjects like nutrition and how these products work and still have so much to learn. Discussing these subjects in detail takes a large amount of time and effort.
I am continuing to learn and do understand that there is a time and a place for everything. As we continue to learn and listen, we will also find that use of all technology is not always best, but that does not mean it should be banned. We should embrace the concept of technology and science in food production and learn how it can best be applied to every different situation.
