What is an implant gun?

 · The pellet is placed, or implanted, under the skin on the backside of the animal’s ear. Each type or brand of implant has a specific applicator, referred to as an implant gun, which is used to properly administer the implant. Current Use of Implants Implants have a long history of use in the beef cattle industry.

What are the techniques of animal implant?

 · Restrain the animal’s head in a head gate to restrict movement. Catch the animal just behind the ears. If the animal will not be calm, use a halter for the safety of both the animal and implant technician. If the animal is moving, the needle can easily come out of the ear and the implant will be deposited on the ground.

Can I use implants on my cattle?

 · The implants dissolve slowly under the skin and do not require removal. The ears of the treated animals are discarded at slaughter and are not used for human food.

When to use androgenic implants in cattle?

 · Cattle produces have utilized all forms of technology to increase production and reduce costs. Most producers are very good at what they do, yet several still aren’t using the highest return on investment technology available in the industry, beef cattle implants.

What is an animal implant gun used for?

Implants are typically made of a powder that is compressed into a small pellet. The pellet is placed, or implanted, under the skin on the backside of the animal’s ear. Each type or brand of implant has a specific applicator, referred to as an implant gun, which is used to properly administer the implant.

How is an animal implant gun important to agriculture?

Implants work by increasing circulating levels of somatotropin and insulin-like growth-factor 1. This causes an increase in the secretion of growth hormone, which increases muscle growth. Many implant products are available for use in nursing calves, stocker calves and feedlot calves.

Why do we use implants in cattle?

Implants enhance muscle synthesis and increase the nutrient requirements of cattle. This increased demand for protein and energy typically results in increased feed intake and additional days on feed to reach the same level of marbling. Implants are generally classified by their potency.

What are benefits of growth implants in cattle What are the concerns explain in detail?

Growth-promoting implants offer beef cattle producers a safe and effective way to increase calf weight gains. Implants increase production of muscle tissue and often reduce body fat production. This results in significant improvements in both growth rate and feed efficiency.

What are benefits of growth implants in cattle What are the concerns?

Growth promoting implants offer beef cattle producers one of the most cost effective and greatest cost-to-benefit ratio management technologies available to increase enterprise profitability. Implants consistently increase body weight gain in nursing calves and stocker cattle across a wide range of production systems.

Are cattle implants safe?

Beef from cattle that have had implants administered is safe for human consumption and contains far less estrogenic activity than many other foods. Implant being placed in the ear of a calf.

When should a calf be implanted?

None of the implants approved for nursing calves are approved for calves less than 30-45 days of age. One implant between 2 months of age and weaning has been shown to have little impact on future productive performance of heifers. However, little benefit has been shown as well.

Why are hormone implants in meat animals good?

Bush says the main reason for the use of implants is for efficiency. They increase the rate of pounds gained per pound of feed consumed. This saves beef producers money by increasing rate of gain and lowering the amount of feed needed for finishing cattle.

In which part of the body are cattle implanted?

The only approved location for implant administration is the middle third of the back side of the ear. All implants must be located within this area (Figure 1). This location has been chosen because the ear is removed and discarded at time of slaughter, reducing any food supply risk.

What is an advantage of synchronizing a cow herd?

Using synchronization protocols improves breeding season logistics and simplicity because it allows producers to plan ahead since they know when to expect cows to come into heat (estrus). This is particularly useful for those who use or who are considering use of artificial insemination (A.I.).

What type of implant is used for cattle?

If the cattle are only on feed for the finishing period, they may be implanted with an androgenic type. The androgenic type (TBA) implant is most effective when it is used in conjunction with animals receiving high-energy rations (more than 80% concentrate barley).

What is the result of implanting cattle?

The result of implanting cattle is the production of a desirable product (lean meat) which takes less feed to produce in a shorter amount of time. It increases weight gain by 5% to 23% and feed efficiencies can improve 3% to 11%.

What are the two major classes of implants registered for use in Canada?

The two major classes of implants registered for use in Canada consist of either estrogenic compounds (estradiol benzoate, estradiol 17B, zeranol) or androgenic compounds (trenbolone acetate (TBA) in combination with estradiol benzoate or estradiol 17ß). It is important to understand which compound and which implant you are using, …

How long does it take for implants to release?

In general, most implants have a higher rate of release (60% to 70% of total implant potential) within the first 30 days following implantation.

How do implanted nutrient supplements help animals?

This is done through the partitioning of nutrients to support more lean tissue or muscle growth. Estrogenic compounds stimulate the animal’s body to increase cell division resulting in increased muscle and skeletal growth rates. Androgenic compounds result in an increase in muscle mass by increasing protein synthesis and slowing the rate of muscle protein degradation.

Where to put implant in ear?

Hold ear with one hand and insert the needle of the implant gun under the skin on the backside of the ear. The implant should be deposited in the middle third of the ear as shown in Figure 2.

Can terminal implants be used in cattle?

All formulations result in improved efficiencies and must be used according to label directions and specified weight ranges. The terminal implants used in finishing cattle should not be used in replacement animals.

Where are cattle implants placed?

The implant should be placed in the middle third of the ear from top to bottom and middle third from skull to the tip of the ear (Figure 1) . Implants are inserted subcutaneously, just under the skin of the ear, using a sharp needle and sanitary technique. Implant retention should be checked after approximately two weeks. Abscessed or lost implants should be replaced at that time. If clean and proper implant techniques are used, replacements should be minimal.

How does implanting beef cattle increase the saleable yield?

The increased ADG brought on by implanting beef cattle increases the saleable yield by increasing both live weight of the cattle and hot weight of the carcass. Increasing either of these endpoints increases the net return for the beef producer. Economics change depending on the given year; however, most implant strategies return $50 to $100 per animal on average.

Can cattle have implants?

To meet the FDA criteria, there cannot be any residue of the implant in edible tissue or chronic physiological or acute toxic affects of the implant on the animal , and the implant cannot cause any mutations or cancerous growths. In short, implants had to go through rigorous testing to ensure that they were safe for use in cattle and would not bring harm to humans. In addition, the FDA specifies that implants must be efficacious–that is, they must do what the label claims they do (i.e., improve ADG and FE).

Is beef safe for humans?

Beef from cattle that have had implants administered is safe for human consumption and contains far less estrogenic activity than many other foods.

When to use implants for calves?

Implant programs used during the finishing phase affect performance and carcass characteristics greater than implants used during the nursing and stocker phase. Calves implanted prior to weaning and then implanted approximately 90 days before slaughter should show no adverse affects in performance compared with unimplanted calves.

What hormones are used in beef cattle implants?

Of the hormones used in beef cattle implants, three are naturally occurring (estradiol, progesterone and testosterone) and two are synthetics (zeranol and trenbolone acetate). Estradiol, progesterone and zeranol are estrogenic, whereas testosterone and trenbolone acetate are androgenic. Estrogenic refers to hormones affecting female characteristics …

How long does it take for a calves implant to lose effectiveness?

Most calves are not weaned, however, until seven to eight months of age, and the majority of implants lose effectiveness within 120 days of implanting. If calves are implanted at birth or before two months of age, the implant will lose effectiveness three to four months before weaning.

How to prevent crushing of implant?

Place the implant in the center one-third of the ear. To prevent crushing the pellets, slowly withdraw the needle as the implant is being administered to allow space for the implant pellets. Close the incision made by the needle by pressing down on the opening.

How to minimize implant failures?

Take the following steps to minimize implant failures: Restrain the animal’s head in a head gate to restrict movement.

Why should you avoid placing an implant in a blood vessel?

Avoid placing the implant in the blood vessel because the absorption rate will be higher, and the implant will be effective for a shorter period of time. Be patient and make sure the implant is correctly placed. Each implant that is improperly placed can mean $15 to $20 of lost income. (Scroll right for more) Table 1.

How do implants work?

Implants work by increasing circulating levels of somatotropin and insulin-like growth-factor 1. This causes an increase in the secretion of growth hormone, which increases muscle growth.

Available Implants

The U. S. Food and Drug Administration (FDA) approves and regulates the use of growth-promoting implants for beef cattle. Implants should be administered only in the FDA-approved location in beef cattle, which is between the skin and cartilage in the middle one-third of the backside of the ear.

Situations Where Implant Use Is Not Appropriate

As a general rule, do not implant breeding cattle, including bull and replacement heifer calves. Implanting bulls can result in problems in reproductive organ development and sterility. Implanting does not improve growth rate or efficiency in bulls.

Implant Handling and Administration

Always use best management practices, including Beef Quality Assurance-compliant practices for implant use in beef cattle. Start by reading label directions on specific implant products. Label directions include information on the age, weight, and/or sex of cattle for recommended use of specific implants.

Beef Safety

The FDA requires no withdrawal period before harvest of implanted cattle. Beef from implanted cattle has very low levels of estrogenic activity compared to many other common foods. Many commonly consumed foods, including vegetables and vegetable products, have much higher estrogenic activity than beef.

Why are people not at risk from eating food from animals treated with these drugs?

People are not at risk from eating food from animals treated with these drugs because the amount of additional hormone following drug treatment is very small compared with the amount of natural hormones that are normally found in the meat of untreated animals and that are naturally produced in the human body.

What hormones are used in beef cattle?

Since the 1950s, the Food and Drug Administration (FDA) has approved a number of steroid hormone drugs for use in beef cattle and sheep, including natural estrogen, progesterone, testosterone, and their synthetic versions. These drugs increase the animals’ growth rate and the efficiency by which they convert the feed they eat into meat.

How does the FDA approve drugs?

The FDA approves these drugs only after information and/or studies have shown that the food from the treated animals is safe for people to eat, and that the drugs do not harm the treated animal or the environment . The drugs also have to be effective, meaning that they work as intended. The labeling for each product provides all instructions for safe and effective use and is approved by FDA. For each approved product, the FDA also makes available to the public via its website a Freedom of Information Summary that summarizes the information that FDA used to determine that the drug is safe for the treated animals, the animal products (edible tissues such as meat) are safe for humans to eat, and that the product is effective.

What are the natural hormones that are produced in animals?

Some of the approved drugs are naturally produced throughout life in people and animals, such as estradiol (estrogen), progesterone, and testosterone. These natural hormones are necessary for normal development, growth, and reproduction. People are not at risk from eating food from animals treated with these drugs …

Where are steroids placed in meat?

These steroid hormone drugs are typically formulated as pellets or “implants” that are placed under the skin on the back side of the animal’s ear. The implants dissolve slowly under the skin and do not require removal. The ears of the treated animals are discarded at slaughter and are not used for human food. Using scientific data, FDA establishes the acceptable safe limits for hormones in meat. A safe level for human consumption is a level of drug in the meat that would be expected to have no harmful effect in humans based on extensive scientific study and review.

Can you give animals ear implants?

Unless otherwise approved and labeled for reimplantation, only one ear implant may be given to an animal during a specific stage of growth. No steroid hormone implants are approved for growth purposes in dairy cows, veal calves, pigs, or poultry. All of the steroid hormone implants are available for over-the-counter purchase in the U.S. and are generally given by the livestock producer at specific stages of the animals’ growth.

Is meat safe for humans?

Using scientific data, FDA establishes the acceptable safe limits for hormones in meat. A safe level for human consumption is a level of drug in the meat that would be expected to have no harmful effect in humans based on ex tensive scientific study and review .

What to do if you don’t implant?

If you choose not to implant, increase your product value by finding premium marketing options.

Does Michigan State University have a cattle implant demonstration?

Michigan State University Extension will offer a BQA demonstration at the upcoming Michigan Cattlemen’s Summer Round-up. This will also include a hand-on cattle implanting demonstration.

Do producers use implant technology?

I have this debate often with producers who don’t understand the Food and Drug Administration (FDA) proven safety of implant technology, the feed savings and increased gains associated with proper implant use. Most producers are on-board and use the technology, but many are not fully utilizing proper implants at the desired growth phase or realizing optimal market value.

How does implanting affect cattle quality?

It is always important to consider the historic quality grade price spreads at the targeted finishing date. Implanting does have an effect on marbling and grading, depending on the implant strategy employed, and this can affect quality grade. An increase in the buller rate has been reported with the use of some implants. Crushing implants has also been blamed on the increased buller rate in some groups of implanted animals. With the modern implanting tools available today, this problem seems unlikely. The effects of climatic changes, ambient temperature, animal handling, commingling, feed stuffs containing fungal or plant estrogens, and implant technique seem more likely to play a role in these observations.

When to implant cattle?

It is important to implant cattle as soon as practical. In suckling calves, the traditional branding time provides an excellent opportunity to implant and vaccinate most of the calves in the herd. Prior to bull turn out, the preferred procedures include vaccination with subcutaneously administered modified live four way viral and clostridial vaccines, and implanting calves older than 45 days old with a product designed for suckling calves. It is important not to implant replacement heifers intended to be kept for breeding purposes unless strict adherence to manufacturer’s directions are followed and never implant bull calves.

How to clean cattle ears?

A number of years ago a method called “scrape, brush and disinfect” was introduced to raise the awareness of ear sanitation prior to implanting by cattle processing personnel. In this method an initial assessment of ear surface cleanliness is made. If the ear is clean and dry, the implant is administered. If the ear is dirty (wet or dry), a dulled steak knife is used to scrape foreign material from the ear prior to brushing the ear with disinfectant solution and implant administration. If the ear is wet, but contains no foreign material, it is brushed and disinfectant solution and the implant given. The type of brush used to clean and disinfect the ears is two-sided with brass bristles on one side and nylon bristles on the other. When the brush is not in use, it is placed in a small bucket of disinfectant solution.

How does TBA help cattle?

In feeder cattle, estrogenic growth promoting implants improve feed efficiency and gain 5-15 percent. Implants which include TBA can provide an additional 3-5 percent improvement in feed efficiency and daily gain. A properly designed re-implant program can sustain implant associated improved performance beyond the payout that would be expected for a single implant. For estrogenic implants used in yearling cattle fed typical feedlot rations, at least a $5 return above the cost of the implant can be expected for each $1 price of a bushel of corn. Adding TBA to an estrogen implant system will return an additional $2 above the cost of the implant for each $1 price of a bushel of corn. For example, if corn costs $3 per bushel, an estrogenic implant would return approximately $15.

How old do cattle need to be to use implant growth promotants?

Because implant growth promotants interact with the production of hormones by the animal, they have not been recommended or approved for use in breeding cattle or calves less than 45 days of age as hormone production in these animals has not yet started.

How much do cattle implants return?

The return on implant investment varies, but only in rare situations do implants return less than $5 per $1 spent. Implants are available for all cattle except calves less than 45 days old and most breeding cattle. Proper scheduling and use of implants should return in excess of $10 per $1 spent.

Where should implants be placed?

This should place the implant outside the cartilage ring at the base of the ear. Implants should never be placed in locations other than the ear. Improper implanting technique and resulting defects are a serious economic concern because of associated performance loss. Defects of concern include abscesses, expelled implants, cartilage embedment, crushed pellets, missing pellets, and bunched pellets. Identification of a problem is not difficult but identifying the cause may be more of a problem. Generally abscesses will be enlarged and will feel doughy. If the abscess ruptures, the implant will be expelled leaving a very small ring of scar tissue. Some implant sites will accumulate fluid that is not associated with an infection and do not seem to be associated with implanting technique. Cartilage embedment should be suspected when the implant feels firmly attached to the deeper tissues of the ear or when you cannot feel the roughened edge of the implant. Published data (Hollis, 1989; Rains and Nash, 1990) outline associated economic loss from these defects. Unpublished data from the University of Nebraska Great Plains Veterinary Educational Center during the summer of 1996 suggest abnormal implants are associated with 0.17 pound reduction in carcass gain in cattle fed 150 days¹. Common sense suggests better performance could be expected in cattle free of implant defects.

How do implant pellets work?

Implants work by increasing circulating levels of somatotropin and insulin-like growth-factor 1. These compounds are produced naturally by the animal and control mechanisms that regulate growth and feed efficiency.

Does it pay to implant a cow?

Does it pay to implant? Again, the simple answer is “yes”. For example, assume an implanted calf on the cow gains and additional 5 percent. At weaning, a non-implanted calf would weigh 600 pounds, so its implanted counterpart would weigh 630 pounds.

Is implanting cattle a new technology?

Implanting cattle is not a new technology. It’s been around for years. It has the potential to add as much as 5 percent more pounds to your calf crop. Yet, fewer and fewer producers are employing the practice. WHY?

Can bull calves be implanted?

Implants are available for nursing calves, stocker calves and/or finishing cattle. Bulls calves intended for breeding stock and replacement heifers should not be implanted.

Can you implant a steer calves?

The simple answer is “yes”. A summary of several research studies revealed that implanting steer calves only once improved daily gains by 0.10 pounds per day, and implanting twice (the second implant would be administered 70-100 days after the first) increased daily gains by 0.13 pounds per day when compared to calves receiving no implants.

Is beef implanted with hormones?

Once more, the simple answer is “yes”. The public concern is focused on the increased estrogenic activity caused by the consumption of beef from an implanted animal. First, there is no such thing as “hormone-free beef”. Hormones are present in all biogogical food sources, whether it’s animal or plant, implanted or not.

How Do Implants Work?

Implants work in conjunction with the natural hormones in the animal’s body resulting in increased weight gain, improved feed efficiency and leaner carcasses. This is done through the partitioning of nutrients to support more lean tissue or muscle growth. Estrogenic compounds stimulate the animal’s body to increase ce…

Why Implant Cattle?

Implanting Techniques

• Restraining the Animal Properly
  Implanting is easier and safer if the animal is held in a squeeze chute with a head restraint. Restraint also minimizes errors in positioning of the implant.
• Sanitization
  Sanitization is critical. The ear should be clean, dry and the implant needle should be sharp and disinfected. Unsanitary conditions can result in abscesses that can wall off the implant and decrease absorption resulting in a loss of effectiveness.
