Why do pigs grind their teeth? The main causes are these
1. Single feed and malnutrition. It is best to feed pigs compound feed. When feeding concentrated feed, it should be paired with green and coarse feed, and minerals and trace elements should be added in appropriate amounts. For example, adding 1%-2% mineral feed to the pig's diet, such as bone meal, calcium hydrogen phosphate, eggshell powder, etc., and adding 0.25%-0.5% salt, etc., has a certain effect on preventing pigs from grinding their teeth. 2. Chronic indigestion in pigs. For pigs with indigestion, the stomach should be strengthened and appetite stimulated. For pigs weighing more than 10 kg, use 0.3 g

Common Problems in Garlic Cultivation and Their Solutions
Problems in Garlic Production and Countermeasures. Yongnian County is the only high-quality garlic production and export base in our province, with a planting area of 180,000 mu and an annual output of more than 100 million kg each of garlic scapes and garlic bulbs. In recent years, due to many years of continuous cropping, long-term asexual reproduction, and improper planting and management measures, the varieties have become severely degraded, pests and diseases have become serious, and yields have stagnated. To this end, we conducted a systematic investigation. At present, the main problems in garlic production in Yongnian County are as follows: severe variety degradation leading to variety degradation

Differences Between Three Soft-Shelled Turtle Diseases and Their Prevention and Treatment Methods
In the process of soft-shelled turtle farming, some farmers cannot clearly distinguish white spot disease, white spot fungus disease and saprolegniasis, and blindly and indiscriminately use drugs when treating turtle diseases, thus affecting the effectiveness of disease prevention and treatment. Therefore, based on recent years of practice at soft-shelled turtle farms, the author summarizes the differences between the above diseases and comprehensive prevention and treatment methods as follows. I. Differences between white spot disease, white spot fungus disease and saprolegniasis in soft-shelled turtles 1. Different pathogens: the pathogen of white spot disease is Aeromonas hydrophila, Aeromonas sobria, etc.; the pathogen of white spot fungus disease is Mucor, which belongs to

How to Cleverly Identify Whether Fish Have Eaten Their Fill
1. Pay close attention to how long the fish take to eat at the feeding tray or feeding ground. If, after a certain amount of feed is put in (the normal feeding amount), the fish finish the feed in less than 2 hours, it means the feed is insufficient and some fish have not eaten or have not eaten their fill, so an appropriate amount should be added. If the feeding amount per ten-day period is fixed and the daily feeding amount within the period is the same, but by the end of the period the feed put in is finished by the fish in less than 2 hours, it means the fish have gained weight and the feed amount should be increased. When feeding compound pellet feed, if the feed has already been finished but the school of fish is still swimming rapidly on the surface layer searching for food and is unwilling to sink into the "second layer of water," it indicates the fish have not eaten their fill. If the school of fish has already dispersed from the feeding tray or feeding ground and there is still leftover bait, the fish have eaten more than their fill, and the feeding amount can be appropriately reduced next time.

Reasonable pig feed formulation is the only way to prevent pigs from losing their appetite
When the temperature rises above 35°C, pigs have low feed utilization and slow weight gain. Therefore, in hot seasons, different feeding methods should be given according to different categories of pigs and different physiological stages of pigs. Boars: feed 2 times a day, and add green feed or thin feed at noon. Mating and exercise are both carried out in the morning and evening; after mating, do not immediately let them go into water to wallow or spray them with cold water. From 1 p.m. to 3 p.m. every day, spray water once on the pigs' bodies and the ground, and reduce light to 8-10 hours. If the number of matings is low, the amount of concentrated feed should be reduced to prevent overfattening and poor libido.

Current Major Diseases of Northern Oyster Mushrooms and Their Control Techniques
1 Soft Rot Disease 1.1 Disease Symptoms The surface of the substrate or the mushroom bodies become covered with a layer of white cottony mycelial threads, fine and soft but growing very rapidly; the gradually infected mushroom bodies develop a light brown morbid condition spreading upward from the base of the stipe, and the mushroom bodies gradually soften and rot; about one week after infection, the mushroom bodies collapse on their own, or topple at the slightest touch, just like Chinese cabbage suffering from soft rot, but the soft-rotted mushroom bodies have no foul odor; mushroom bodies not yet soft-rotted grow extremely slowly, the caps gradually turn earthy yellow, lifeless and dull, clearly different from normal mushroom bodies; infected substrate no longer

A Detailed Guide to Common Lily Diseases and Their Control Methods
1. Bulb and scale rot and stem diseases caused by Fusarium. Symptoms: In plants with bulb and scale rot, growth is very slow and the leaves are pale green. Underground, brown spots appear at the top of the scales, on the sides, or where the scales join the basal plate, and these spots gradually begin to rot. If the basal plate stem is infected, the entire bulb will rot. The stem and leaf diseases caused by Fusarium are diseases that infect the above-ground parts. The identifying sign is that the basal leaves turn yellow before reaching maturity, and the yellowed leaves turn brown and drop off. On the stem

Deep processing of sweet potatoes brings good returns, giving farmers a new way to increase their income
I. Crispy rice crust 1. Raw material preparation. Select 10 parts of fresh sweet potatoes with a high dry matter content, cut off the roots and stems, and wash them with water. Separately select 1 part of highly sticky glutinous rice, soak it in water and wash it for 30 minutes, then drain off the water. Next, put the sweet potatoes and glutinous rice into separate pots, add water, and steam them thoroughly over high heat for later use. Then put the mashed cooked sweet potatoes and glutinous rice, while still hot, into a bucket, and quickly pound them with a thick stick into a paste. At the same time add a small amount of white sugar water to increase sweetness and flavor. 2. Spreading the paste. Take a clean cloth sheet and spread it flat on a sun-drying mat,

Common pests and predators in soft-shelled turtle farming and their control methods
The main predators of soft-shelled turtles include rats, snakes, birds, ants, mosquitoes, etc. They mainly harm turtle eggs and juvenile turtles under 1 year of age; turtles over 1 year old with strong constitutions are rarely harmed. Among them, rats cause the greatest harm to turtle eggs. In the dead of night, which is the good time for turtles to lay eggs, rats also come out of their holes and move frequently around the egg-laying sites. On one hand, they disturb the normal egg-laying of turtles; on the other hand, rats dig holes all over the sand bed, causing the turtle eggs to vibrate and leading to embryo death. Juvenile and young turtles are also easily surrounded and

I. Bacterial Diseases 1. Vibriosis Pathogen: Vibrio parahaemolyticus. Symptoms: The appearance of ulcers on the body surface of diseased fish is the typical feature of this disease. In the early stage, there are petechiae, ecchymoses, and irregular red patches on the body surface, mostly seen on the abdomen and tail. In severe cases, there is bleeding and ulceration of the lower jaw, congestion and redness at the fin base, missing fin rays, and rotting of the caudal peduncle muscle, forming hemorrhagic ulcers. The liver, spleen, kidney, and intestine are all congested, the liver is enlarged and earth-yellow in color, and there is pale yellow mucus in the intestinal tract. Microscopic examination of the tissue at the lesion site reveals slightly curved bacteria. Epidemiology: This disease
