Growth stimulants for cattle: the most effective means, rules of use, drug safety

The use of growth hormones and natural fertilizers

The goal of any cattle breeder is to raise calves and produce stock that has the desired characteristics. For this reason, young animals must be provided with everything they need from the first days of life. In addition, they are faced with the task of quickly obtaining material profit.

Interestingly, livestock farming is taxed regardless of its income. As a result, farmers have to use all kinds of means to stimulate the growth of livestock. Nowadays various fertilizers are sold for this purpose. But you should choose the right product, taking into account the recommendations of a specialist and the financial capabilities of the farm.

It should be noted that Russian farmers highly value organic products. Therefore, when natural additives are used as growth stimulants, the cost of the resulting meat products increases.

Among the advantages of using drugs to stimulate growth, the following should be noted:

• muscle mass increases;
• the body's resistance to all kinds of pathologies increases;
• a larger number of individuals comply with existing standards, thanks to which it is possible to maintain high-quality livestock;
• the products are safe for people;
• animal productivity increases;
• digestive function is normalized;
• the cows' appetite is activated.

Important! The main advantage is the ability to quickly make a profit after selling meat and milk.

Rules for the use of cattle growth accelerators

All growth stimulants are used not only for cattle, but also for other animals. Depending on the type of mammal, the pattern of use also changes.

In the first months of a calf's life, stimulants are not used. The young animals are fed high-quality starters, hay and milk. Rapid growth stimulants will be required when the bull is put into fattening.

Due to the wide variety of growth accelerators, there is no single scheme for their use. Each stimulant must come with instructions. If it is not there, most likely the drug is intended for other purposes. The rapid growth when using this remedy is either a coincidence, a side effect, or self-deception.

The nucleopeptide is used for rapid fattening of bulls. And instructions for using the product specifically for this purpose exist. To stimulate the immune system, the nucleopeptide is administered intramuscularly or subcutaneously at 0.1-0.2 ml/kg of live weight every 24 hours for a course of 3 days.

When using it as a stimulator of rapid growth for fattening calves, injections are given subcutaneously in the middle part of the neck. Dosage 0.1-0.2 ml/kg. No more than 30 ml can be injected into one place. Injections are given 4 times with an interval of 15 days.

Attention! When using nucleopeptide, the calf must be fed a high protein diet.

The basic rule for using fast growth products is high-protein concentrates ad libitum. You can use the best and most expensive growth stimulants to promote rapid growth, but if you don't feed the calf, it won't grow. He simply will have nowhere to get “building material” for his body.

To get good muscle mass, calves will have to be fed well; the principle “to earn a lot, you need to invest a lot” works here.

What is a growth stimulator

A growth stimulator is a special additive, a medication that accelerates metabolic processes and ensures rapid growth. There are two types of similar preparations for cows: natural or artificial.

Natural growth stimulants include all kinds of supplements, the nutritional value of which makes it possible to achieve the desired effect without the use of dangerous or even prohibited methods. Among such dietary supplements, yeast, fish oil, etc. should be noted.

These stimulants have some benefits and are completely harmless. The main advantage is that they can be added to the food of young animals, and this will not harm their health. But it should be noted that it is necessary to strictly adhere to the dosage. In addition, if they are used in combination with other supplements, this will also not harm the body.

Growth hormones for cattle

The animal’s body independently produces hormones that affect linear growth and weight gain. The main substance produced in the brain is called somatotropin. When it is in excess, if certain drugs are artificially administered, a disease such as gigantism occurs.

There are also other hormones that do not affect the growth of the body as a whole, but only the increase in muscle mass. The production of these substances (androgens) increases significantly in males when they reach puberty. If drugs containing them are artificially administered, the animal’s body stops independently producing such hormones.

Antibiotics are often used to stimulate growth. Some types of drugs have an anabolic effect (especially when combined with vitamin supplements). Tissue preparations for increasing muscle mass are also popular in animal husbandry. They increase gains by 15-25% and are completely legal, unlike steroids. Such drugs are even recommended for animals. Veterinarians advise using them to enhance the protective functions of the body of young animals and for those individuals who have inhibited growth.

Use of artificial growth stimulants

Many livestock breeders use such additives starting from 21 days after the birth of a calf. This allows you to achieve the desired results in a shorter time. In addition, if you use fertilizers correctly, no adverse reactions will occur.

Such drugs are at the same time antibiotics, which helps reduce the likelihood of pathologies occurring. Among the main advantages of using artificial hormonal and non-hormonal drugs, the following should be noted:

• ensure rapid development;
• calves can be introduced to hay earlier;
• appetite increases;
• animals recover quickly from illness.

It is worth noting that you can use both natural and artificial additives at the same time. Although this is done in rare cases, as this leads to an increase in the cost of products produced on the farm.

Although there is some risk if antibacterial drugs are added to food or drink. Indeed, with prolonged and uncontrolled use of such additives, problems with the digestive tract, heart and liver may appear. So, before you start using a certain product, you need to consult a veterinarian. In addition, the veterinarian will tell you exactly what dosage to give the supplement to calves and mature animals.

There are many synthetic growth promoters available for cows today. Let's look at the most popular of them.

Katozal

This is a tonic drug that helps stimulate metabolism, increase the body’s resistance to the effects of negative factors, and accelerate the growth of cows. This is a matoloxic drug; when used in the recommended dosage, there is no locally irritating, sensitizing, teratogenic or embryotoxic effect. In addition, these additives are not able to accumulate in the body of cattle, and as a result, in meat products.

This product is recommended not only for cows, but also for poultry. It is used to increase tone during calving, as a warning against consequences after childbirth, to prevent the development of diseases that appear due to a lack of calcium and magnesium, and to increase the activity of muscle tissue.

Gamavit

This product is based on denatured emulsified placenta (PDE) and sodium nucleinate. The additive is a solution that contains bioactive elements that help optimize metabolic processes, normalize the blood formula, increase the bactericidal activity of blood serum, and provide an immunomodulatory and general biotonic effect.

It is a biogenic stimulant and adaptogen that helps reduce postnatal mortality, increase the viability of offspring, increase muscle performance and resistance to excessive loads and stressful situations. It is an excellent source of metabolic substrates that promote growth.

The product is used for preventive and therapeutic purposes, as a biotonic agent for:

• anemia;
• hypovitaminosis;
• diseases of infectious and invasive etiology;
• pyometer;
• intoxications;
• after operations;
• against the background of toxicosis during pregnancy and childbirth;
• when preparing cows for an exhibition, competition or transportation.

Fosprenil

It is a product of phosphorylation of coniferous polyprenols. The product has an antiviral effect against distemper viruses, parvoviruses, adenoviruses, coronaviruses and some other viral infections of cattle.

The supplement helps modulate the body's natural resistance and has anti-inflammatory, hepatoprotective and detoxic effects. It is used for therapeutic and preventive purposes against diseases of a viral nature (plague, viral enteritis, infectious hepatitis and adenovirosis, panleukopenia, infectious peritonitis and rhinotracheitis).

Butofan

This is a medicine containing butaphosphamide and cyanocobalamin (vit. B12) as active ingredients. Helps normalize metabolic and regenerative processes, stimulate protein, carbohydrate and fat metabolism, the body's resistance to the negative effects of external factors, accelerates the growth and development of calves.

Thanks to the butophosphamide included in the composition, liver function improves, metabolism is stimulated, the motor activity of smooth muscles is activated, and bone tissue is synthesized more quickly.

Thanks to vitamin B12, the hematopoietic function and the production of nucleic acids are activated, suppressor lymphocytes are normalized, and this component takes part in the production of methionine, favors the formation of glycogen, and the mobilization of energy resources necessary for the synthesis of deoxyribose and DNA.

The use of natural growth stimulants

Vitamin complexes help restore the balance of microorganisms, due to which young individuals gain weight faster. The main thing is to choose the right drug that strengthens the immune system in animals to accelerate muscle gain.

Now such feeding is allowed to be used already 3 weeks after the birth of a calf. Natural supplements offer some benefits:

• no adverse reactions even if the dosage is exceeded;
• immunity increases;
• help prevent problems with the skeletal system;
• help improve appetite;
• gaining weight faster.

Every farmer should take into account that such fertilizers should be added to food constantly, and more of them will be required in comparison with artificial analogues, which as a result leads to an increase in the cost of products. Although in this case, cattle can be slaughtered at any time, without waiting a certain time as when using synthetic drugs, when it is required that the body cleanse itself of the drug in a natural way.

Let's look at the most popular natural growth stimulants for cows.

Nucleopeptide

This product is an extract from the spleen of cows, based on peptides, nucleosides, nucleotide bases and other biologically active formations. The drug has a complex effect on metabolism, regulates hormone levels and protective functions in the cow’s body. Helps increase the production of thyroid and androgenic hormonal substances within normal limits.

Thanks to thyroid hormones, the animal gains weight faster, tissues grow and differentiate. The drug helps increase resistance in the body due to stimulation of the production of interferon mediators, resistance of liver tissue to the effects of toxic substances, and a positive effect on the skin and hair.

In the process of using the product, the average daily weight gain significantly increases by 12-25%, the exchange of feed is activated, which is important for cows that are raised specifically for further slaughter. Along with the Nucleopeptide, the animal must be given antibiotics, vitamins, minerals and other chemotherapy drugs.

Important! If given in the recommended dosage, this drug does not have any irritating, toxic or sensitizing effects.

Eleovit

This is a drug that contains everything necessary for calves so that they develop faster, but without any harm to health. The main requirement is strict adherence to the dose. The drug is administered by injection, starting from six months of age, every 14-21 days up to a year.

Use of antibiotics

Antibacterial drugs act differently on calves and adults. Numerous experiments prove that when taking antibiotics, young animals begin to grow faster and develop better. Up to 6 months there is an increase in body weight by 14%. After six months of age, growth rates begin to decrease, and the response to medications weakens. Calves who were given the drugs weighed 10% more per year than young animals who did not take antibacterial agents. The following changes in the body were observed in animals:

1. growth increases;
2. All parts of the stomach become larger: the rumen, book, mesh, abomasum;
3. there is an increase in intestinal length;
4. the weight of the heart, lungs and liver is greater than that of calves that grew up without antibiotics;
5. the level of red blood cells in the blood increases by 16%; this helps increase hemoglobin;
6. leukocyte profile improves;
7. qualitative change in protein digestion;
8. minerals are better absorbed.

Blood counts and internal organ volumes are within normal limits. As antibacterial drugs, calves received:

• penicillin;
• streptomycin;
• chlortetracycline;
• oxytetracycline.

The drugs were introduced into the feed, but this had little effect on the body. Injections of 2 mg of antibiotic per 1 kg of calf weight are more effective. The most effective are drugs for cows of the tetracycline group. There is no need to increase the dosage. This leads to deterioration in the health of calves. They gain weight, but they experience obesity in the internal organs and the deposition of subcutaneous fat. The functioning of the gastrointestinal tract and organs of other systems is disrupted. When using antibiotics, you should consult your veterinarian. Self-administration of drugs to young animals is unacceptable.

The drug “Biovit-40” can replace antibiotics. When using the drug, the cost of meat and milk decreases. The product is used if the development of young animals is not good enough.

Veterinarians recommend adding an additive with a combined composition to the feed of bulls: tetracyclines and bacitracins - 50.0 kg/t of feed, grisin - 4.0 kg/t of feed. The composition is recommended for calves from 1 to 12 months. For animals older than 12 months, another additive is used: tetracyclines and bacitracins - 20.0 kg/t of feed, grisin - 2.0 kg/t of feed.

Experts say that the final product, meat and milk, contains antibiotics within normal limits. Otherwise, the raw materials are rejected.

Content standards in raw milk:

• levomycetin – 0.010 units/g per cm3;
• tetracyclines – 0.010 units/g per cm3;
• streptomycin – 0.500 units/g per cm3;
• penicillin – 0.010 units/g per cm3.

The standards for the content of antibiotics in preparations for bulls are constantly adjusted and reduced by law. In addition to antibiotics, cattle supplements with a vitamin and mineral complex are used in livestock farming.

Popular vitamin preparations for accelerating the growth of calves

Although today there is a wide range of growth stimulants for cattle, there are some vitamin preparations that are increasingly popular among farmers raising cows. Most often, to stimulate growth, animals are fed:

• Biovitom-80;
• Eleovit;
• Nucleopidome;
• Penicillin;
• Steptomycin.

The animal body perfectly absorbs such drugs, and they are completely harmless to humans. In addition to stimulating growth, they have a positive effect on the immune system and digestive tract. They should be used both as a feed additive and in the form of intramuscular injections, which gives a greater effect, according to cattle breeders.

What are growth hormones?

In addition to antibiotics, there are other medications, namely vitamin complexes, which restore the balance of vitamins in the body and help calves stay healthy. They have an impact on the general condition of bulls and also have an effect on the immune system.

Antibiotics and growth hormones

You can give antibiotics to young animals as early as 21 days. They help fight microbes, tone muscles, and strengthen bone tissue. There are many supplements available on the market, so you should talk to your veterinarian before purchasing. Only this person can correctly determine which microelements are missing in the body and what you need to pay attention to. Vitamin supplements have their own specialization; there are several that contain iodine, potassium and iron. The additive “Biovit-80” is increasingly found on the market. It is necessary to accelerate growth and also eliminates the occurrence of diarrhea.

This is why this drug is so valued among farmers, since diarrhea is one of the most common ailments in cattle. This remedy is allowed for calves from 21 days. If you follow the instructions, you can protect the individual from many diseases, for example, from staphylococcus or salmonella.

The composition of the Eleovit product includes all the necessary components that provide microelements for the development of young animals. It is important that the dose is maintained. You can start giving injections to individuals from six months old; the instructions must be strictly followed. The frequency of the procedure is every 21 days. Young animals under 12 months of age are given 3 mg of the drug.

The use of vitamins and stimulants to accelerate the growth of calves

When fattening young cattle to produce meat products, you can use one of the existing schemes, which involve the use of growth stimulants:

1. The short one is the proper maintenance of young individuals with enhanced nutrition, which allows them to gain weight of approximately 400 kg by the age of 5-6 months. This way you can get very tender meat. But we must take into account that the nutrition of livestock in this case should actually be enhanced. Experts recommend using natural and artificial supplements in parallel.
2. Medium – helps the animal gain the necessary weight by about 7-8 months of age. In this case, a moderate diet is required: you need to make sure that the calf is not hungry, but also does not overeat. By the end of this period, the bull can gain approximately 500 kg, and the meat products will be juicy and fatty.
3. Long-term – lasts approximately 18 months. By the end of this period, the calf will reach a weight of approximately 550 kg, which allows for maximum profit. But in this case, it is important not to “overcook” the bull, as this risks producing tough meat that has lost its qualities.

Impact on the human body

Interestingly, the use of hormonal substances to stimulate the growth of cattle does not affect the human body when ingested with milk or meat. To avoid problems, it is recommended to use harmless antibacterial drugs and bioactive additives as growth stimulants, otherwise the resulting products will not pass veterinary control before sale.

It is better to buy stimulants at a specialized retail outlet, where all products are certified. This helps reduce the likelihood that meat and milk obtained from animals will fail veterinary inspection.

However, even approved additives must be excluded from the diet or stopped injecting 1-3 weeks before the planned time of slaughter of the animal. The duration of this period is determined by the type of artificial drugs used. As for natural remedies, their use should be stopped a couple of days before slaughter.

The law prohibits the sale of meat and milk produced on livestock farms if there are no appropriate veterinary control documents. At a minimum, these products are subject to write-off. In case of partial or full sale of such products, the entrepreneur is subject to a fine.
