What is the most suitable body weight for snakes used for breeding

Snakes used for breeding must be in their youth, and the same species also has specific weight limits, so as to ensure the quality of the breeding snakes. Generally speaking, the body weight specifications of breeding snakes must be controlled as follows: small snake species about 100-150 g each; medium snake species 150-350 g each; large snake species about 250-700 g each.

Pig poisoning is mostly caused by feeding them half-cooked feed
Some farmers feed pigs with half-cooked feed, and shortly after eating, the pigs become restless and agitated, walk unsteadily, have difficulty breathing, and die from convulsions. This is food poisoning, and the main causes are as follows: First, putting green vegetables in a pot and cooking them slowly over low heat for a long time without stirring them can easily produce a toxic substance called hydrocyanic acid, and pigs are highly susceptible to poisoning after eating it. Second, the feed is not cooked thoroughly and spoils after being left standing for a long time.

When is the most suitable time to harvest wine cap mushrooms?
The wine cap mushroom (Stropharia rugosoannulata) is larger than common edible mushrooms. A common edible mushroom weighs about 10 grams per cap, while a wine cap mushroom weighs around 60 grams, with the heaviest reaching up to 2500 grams, and a diameter of 5-40 cm. It should be harvested in a timely manner according to its maturity and market demand. From pinning, that is, the appearance of the white primordium, to maturity, the fruiting body takes about 5-10 days, varying with temperature. At low temperatures it grows slowly, but the mushroom body is thick and fleshy and the cap is not prone to opening. Conversely, at high temperatures it presents a small cap shape and opens easily. Throughout the entire growing period, 3 flushes can be harvested.
