dosage

[Jeffery Escobar]

All medications and most feed supplements (e.g., enzymes, probiotics, prebiotics, organic acids, essential oils, phytochemicals, extract, fermentation products, etc.) indicate in the label the appropriate dose of the product or a suggested dose for the product. The manufacturers of medications and feed additives have spent considerable resources to determine the most effective and economically viable dose for their product. Therefore, it is always a great start to begin using the suggested dose for each product. When in doubt, you should always you nutritionist, veterinarian, the product manufacturer representative or an appropriate authority to inquire more about the recommended dose for a particular product or to ask questions about how the dose of one product may interact with the dose of another product.

These are the simple basic rules very helpful for the calculation of feed additives and medicine.

HOW DO YOU DETERMINE THE APPROPRIATE DOSAGE FOR DIFFERENT AGE GROUPS OF BIRDS?

The following should be considered as general information; however, you should always seek professional advice, specific to your individual circumstances.

Proper dosage of additives and medications in poultry is critical for effectiveness, bird health, and compliance with regulations. The approach to dosage calculation depends on whether the substance is provided via feed, water, or as a medication. Younger birds generally consume more feed and water per unit of body weight due to growth demands, affecting how much additive or drug they receive.

Feed Additives – dosage is typically specified as mg or g per kg of feed.

Example calculation – if the additive dose is 100 mg/kg and you mix 5,000 kg of feed, then you need:

100 mg/kg × 5,000 kg = 500,000 mg = 500 g

Water Additives And Medications – dosage often specified as amount per litre (or per 1,000 L) of water, or per kg body weight per day. Actual water consumption varies due to flock age, bodyweight, climate, and health.

Example calculations:

Body Weight Approach

• Find the total body weight of the flock.
• Use the dosage per kg body weight (e.g., 10 mg/kg/day).
• Multiply dosage by total flock weight to find the total amount needed per day.
• Adjust the stock solution accordingly to deliver in the daily estimated water intake

20,000 birds x 1.3 kg average bodyweight x 10mg/kg/day = 260,000mg = 260g

Concentration Approach

• For products like coccidiostats or antibiotics, instructions might say: “Mix 1L of product in 1,000L water for 3-5 days”.
• Accurately measure water consumption to ensure the birds receive the recommended therapeutic dose.

Medication Dosage – antimicrobials and other medications are commonly dosed per kg body weight (e.g., enrofloxacin at 10–12.5 mg/kg/day). The optimal dosage may be determined by factors such as the minimum inhibitory concentration (MIC) for microbial infections, medication pharmacokinetics, and flock health status.

Total Dosage (mg) = average body weight (kg) × number of birds

20,000 birds x 12.5mg/kg = 250,000mg = 250g

Hypovitaminosis A, or Vitamin A deficiency, is a common health issue in birds, particularly those fed seed-based diets. It can lead to various health problems affecting the skin, respiratory system, vision, and overall well-being. Symptoms include dry, flaky skin, sticky eyelids, thickened skin on legs and feet, and potential blindness. Proper diet and supplementation are crucial for prevention and treatment.

Determining the correct dosage for birds of different ages is a complex process. However, a bird’s dosage can be determined by following a few simple rules. Generally, the dosage is determined according to the weight, age, and health status of the bird. In addition, the type of drug and the severity of the disease are also considered while determining the dosage.
