Key Points and Detailed Operating Methods of Boar Artificial Semen Collection
An ideal semen collection method should meet the following four conditions: (1) it can collect all the semen ejaculated by the boar in one ejaculation; (2) it does not affect semen quality; (3) the boar's reproductive organs and sexual function will not be damaged or affected; (4) the instruments and equipment are simple and convenient to use. The methods of artificial semen collection include: the electrical stimulation method, the artificial vagina method, the hand-grip method and the cylinder-grip method. 1. The electrical stimulation method is to insert a probe with electrodes into the boar's rectum and stimulate the ejaculation center of the reproductive tract with low-voltage pulses to induce ejaculation; even if the penis is not fully

Correct Methods and Operating Steps for Injecting Pigs
Injecting pigs is the main method for preventing and treating pig diseases. The commonly used injection methods include intramuscular injection, subcutaneous injection, intravenous injection, and intraperitoneal injection. Intramuscular injection: muscle tissue is rich in blood vessels, so the injected medicinal liquid is absorbed relatively quickly; in addition, there are fewer sensory nerves distributed in muscle, so the pain caused is relatively mild, making it the most commonly used injection method. The injection site is generally chosen at the well-fleshed buttocks or neck. During injection, first clip the hair and disinfect, then hold the syringe with the right hand and insert the needle vertically. The depth can be determined according to the size of the pig, and generally

Correct Methods and Operating Procedures for Venom Collection from Snakes
There are two methods for collecting snake venom: "dead collection" and "live collection." "Dead collection" is a special *destructive method in which the venom glands are excised from the head of a venomous snake cut off by a processing facility, or from rear-fanged venomous snakes and sea snakes with low venom yield after they have been anesthetized and killed; it is used only occasionally under special circumstances. Generally, the "live collection" method is used so as to make full use of snake resources. Several "live collection" methods are briefly introduced below. (1) Electrical stimulation venom collection method: This method uses a weak electrical stimulation device such as a "needle anesthesia instrument," with a specially made electrode to stimulate the inner wall of the snake's mouth.
