Comparison table for the use of needles for pigs, with common model and length

For pigs born to 10 kilograms, the commonly used needle length is 0.5-0.75 inches and the needle number is 20-21. 10-30 kg pigs: the commonly used needle length is 0.75-1 inch and the needle number is 18-19. 30-100 kg pigs: the commonly used needle length is 1-1.25 inches and the needle number is 18. Pigs weighing more than 100 kilograms: the commonly used needle length is 1.25-1.75 inches and the needle number is 16.

Type and length of needles commonly used in pigs

1. For pigs born to 10kg, the common needle length is 0. 5-0. 75 inches and the needle number is 20-21.

2. For pigs with 10-30kg, the common needle length is 0.75-1 inch and the needle number is 18-19.

3. For pigs with 30-100kg, the commonly used needle length is 1-1.25 inches and the needle number is 18.

4. For pigs above 100kg, the commonly used needle length is 1.25-1.75in, and the needle number is 16.

Second, choose the mode of injection

There are four general methods of drug injection, of which intramuscular injection and subcutaneous injection are more commonly used, while intraperitoneal injection and intravenous injection can only be operated by or under the supervision of veterinarians.

Third, calculate the injection dose of each pig

It is necessary to follow the instructions for the use of vaccines or veterinary drugs. The general dose is expressed in terms of unit body weight (kg) and the dose to be injected (ml). Milliliters are written as "mL" or "ml" (1ml=1cc). The dose required for each pig is calculated as follows.

1. During this period, the weight of pigs is expressed in kilograms (kg).

2. The dose needs to be determined, which will be written in the general instruction manual.

3. Calculate how many milliliters (ml) need to be injected into each pig at the recommended dose.

Fourth, choose syringe

The size of the syringe is different, and the materials are generally glass, metal and plastic. Only by choosing the syringe of the right size can we ensure the accurate injection of the product. During this period, we need to choose a durable and convenient syringe.

Choose to use needles

1. The diameter (type) and length of the needle are also different. Generally, when selecting the needle, the diameter and length of the needle and the characteristics of the injection product should be taken into account. The general rule is to choose the needle with the largest diameter (the largest number) and the smaller length as far as possible.

2. Now there are two kinds of needles on the market, the first is a reusable needle made of metal at the base, and the other is a disposable needle made of plastic or aluminum, but no matter which kind of needle is used, it needs to be detected by the metal detector of the meat factory.

VI. matters needing attention in injection

When using a syringe with a needle, load the right amount of medicine to make sure there is no gas in the needle, stand the needle upright and tap to let the bubbles rise, then gently push the piston to vent the air, Baoding pigs for accurate injection, make sure the injection site is clean, and insert the needle and inject the medicine quickly and steadily.

7. Treatment of damaged needles

If the needle is broken in the pig, you need to make a permanent mark on the pig, such as ear marking, and record the diameter (model) and length, brand or type of needle, as well as the location of the needle, such as neck, shoulder or hip, as well as the responsible person and the presenter, and then provide the details of the needle pig in the body to the pig buyer or slaughterhouse.
