Correct Methods and Precautions for Mixing Fishery Drugs
With the increase in the variety of fish species stocked in polyculture ponds and the rise in stocking density, the chance of different fish diseases occurring simultaneously in different fish in the pond has greatly increased. In general, the effect of using a single fishery drug is poor, while the method of mixing fishery drugs can significantly improve the therapeutic effect. 1. Principles of mixing. Do not affect the chemical stability of the active ingredients of the drugs; do not increase toxicity, and the ideal effect is to increase efficacy without increasing toxicity; the drug effects should be reasonably matched and complement each other's advantages; do not increase the cost of medication. 2.

The correct method and key operational points for plucking bristles from live pigs
Plucking bristles from live pigs is best done in summer, as this is precisely the molting and bristle-shedding period. Five minutes before the first plucking begins, feed the pig some distillers' grains type feed, so that the pig's pores are dilated. Then, while the pig is eating or lying quietly, use one hand to gently stroke the pig's body, and with the other hand gently pull a bristle to test whether it comes off with a light tug. If the hair root is already loose, it means this is the most suitable time to pluck. When it is determined that the hair roots are loose, a fine wooden comb can be used to comb the pig's bristle ridge area from back to front. The bristles can then be combed off, sorted, put into a pre-prepared paper bag, and stored

How to store new tea? Master the correct preservation methods
Every spring when new tea comes on the market, households generally buy it in fairly large quantities, and since they cannot use it all up at once because of the large amount, the following methods can be used for storage and preservation: 1. Quicklime storage. Quicklime storage of tea is the most commonly used and most convenient method of tea preservation. The method is to use a small-mouthed tinplate bucket that is rust-free and odorless, or a dry, clean earthenware jar or pottery pot that is also free of any strange odor (a blue sand jar produced in Yixing is better). Put the quicklime into a cloth bag and seal it to make a lime bag. Before putting in the tea, first roast it briefly over a gentle fire, so that the tea is fully dry

Detailed Explanation of the Correct Method and Operating Steps for Bagging Pears
1. Bagging time. Generally, bagging begins 25-30 days after petal fall. 2. Preparation before bagging. Bagging can be done after strict flower and fruit thinning and spraying. When bagging, further select the fruit, choosing drooping side fruit with a long fruit shape and tightly closed calyx end; such fruit tends to grow into large fruit, and because leaves block the sunlight, sunburn can be avoided. After selecting the fruit, carefully remove the petals, sepals and other attachments adhering to the stalk end, because long-term attachment of these substances will cause excessive humidity at the part where the fruit is attached and form water rust. 3-5 days before bagging

Correct method for eye-drop and nose-drop administration in chickens
Eye drop: For young chicks, gently hold the chicken with the left hand so it does not move around, take the eye-drop bottle in the right hand, and gently place one drop into each eye, left and right. Wait until the chicken completes one blink and the solution is fully absorbed into the eye before letting go. Otherwise, if you release too early, the solution stays only on the surface of the eyeball and does not enter the eye, and the chicken will easily shake its head and fling the solution out, failing to achieve the purpose of immunization. When immunizing adult chickens, simply open the cage door and hold the chicken by the neck. (Only the head and neck of the chicken are outside the cage; the body is inside the cage.) The eye-drop method is the same as for young chicks. Nose drop: Nose drop is also a method of immunizing chickens
