What are the key points of adult fish farming management after the beginning of autumn
After the beginning of autumn, the water temperature begins to drop, and the fish gradually feed vigorously again. This is also a golden period for fish production and growth, so management should be strengthened. The following key points should be grasped in particular: First, strengthen bait feeding. At this time, feeding should focus on concentrated feed, with emphasis on fattening the bottom-feeding fish. At the same time, attention should be paid to the combination of varieties in concentrated, coarse and roughage feeds to ensure that the fish feed is fully and comprehensively nutritious. Grass carp should be properly fed green grass, black carp should be fed snail feed, and silver carp and bighead carp should also be properly fertilized. After the beginning of autumn, fertilizer should be applied in small amounts and frequently, mainly inorganic fertilizer, and it should also be specifically controlled according to the condition of the fish, the fertility of the water, the weather, and so on.

Breed Characteristics and Farming Introduction of Cenxi Three-Yellow Chicken
The Cenxi Three-Yellow Chicken is a historically famous chicken breed from Guangxi supplied to Hong Kong, China and Macao, China, and is currently a high-quality local native chicken in Guangxi that has undergone strict systematic breeding without introducing any foreign bloodlines. It has a small body size, splendid appearance, tender meat, fine bones, and a lively, active pecking nature. In 1983, it was awarded an honorary certificate by the National Ministry of Foreign Trade. Over the past 20-plus years, relevant researchers have carried out a series of scientific and technological research projects on the Cenxi Three-Yellow Chicken, continuously improving the product's technological content and quality. Of the seven completed research projects, four won provincial and ministerial-level science and technology progress awards. Starting in 1999,

Pietrain Pig Breed Characteristics and Farming Introduction
The Pietrain pig originates from Belgium. Its body is square-shaped, wide and short, with fine bones and short limbs, and particularly well-developed muscles. Its coat is grayish-white with black patches, and its ears are medium-sized and tilted forward. The average litter size is about 10 piglets. It is reported that at 90 kg body weight, growing-finishing pigs have a carcass lean meat percentage of 66.9%, a daily weight gain of 700 grams, and a feed conversion ratio of 2.65. For commercial meat pigs, the growth rate decreases significantly after 90 kg. Pietrain pigs have severe stress reactions, and about 50% of pigs carry the halothane recessive gene. When purebred Pietrain is used as the sire for crossbreeding, pale soft exudative meat (

Practical Tips for Saving Feed in Yellow Catfish Farming
Currently, yellow catfish (Pelteobagrus fulvidraco) farming is quite widespread and is a major species for increasing income among fish farmers in many places. However, during the farming process, many farmers, in their one-sided pursuit of output, do not know how to save feed and continuously put excessive feed and fertilizer into the aquaculture water. This not only causes farming costs to rise day by day, but also continuously deteriorates water quality, affecting the growth of yellow catfish and resulting in low farming benefits. How can feed costs be saved in production practice? Strictly remove trash fish and disinfect the pond. Pond disinfection can kill wild trash fish, reduce competitors for food

How can the disease prevention system be improved in soft-shelled turtle farming?
1. Build farming facility conditions that meet ecological requirements, including farming engineering facilities, water source and water quality management, and other aspects. 2. Implement scientific feeding management and daily operations, and use high-quality, complete, diversified feed free of pathogen contamination. 3. Select healthy seedlings for farming. As far as possible, breed hatchlings and young turtles locally, and at the same time try to avoid introducing seedlings from other places, especially imported seedlings, to prevent secondary infection by pathogens. Even if they are introduced, strict quarantine and isolation observation must be carried out.

Summary of the Trial on Introducing and Farming the Giant Mudskipper
The giant mudskipper is a small warm-temperate, humid-tropical coastal economic fish. It prefers to inhabit harbors and estuarine brackish waters and intertidal muddy flats, living in burrows it digs. Its flesh is delicious and nutritious, making it a specialty species with development prospects. To fill the gap in local aquaculture, in 2006 we actively introduced giant mudskipper fry and conducted farming trials. After several months of exploration, the trial succeeded, and we have basically mastered the farming techniques for the giant mudskipper. The farming method for the giant mudskipper is briefly described below. I. Basic information of the trial

Pig-and-chicken circular farming model boosts feeding efficiency
The new technology of efficient circular pig-and-chicken farming is a practical technique particularly suited to rural farmers. The method is as follows: ferment chicken manure by the lactic acid method to feed pigs. There are many ways to feed pigs with chicken manure, such as drying it, feeding it fresh, and conventional fermentation, but the lactic acid fermentation of chicken manure is best. This is because this method can turn chicken manure into a high-quality pig feed with good palatability. The fermentation method is: first dry the chicken manure to 70% dryness, then mix an appropriate amount of lactic acid bacteria and 10 kg of wheat bran or rice bran into every 100 kg of chicken manure, put it into non-toxic plastic bags or other containers

What are the prospects for snake farming? An introduction to the development prospects of snake farming
Because snakes have significant economic value, many people, directly driven by profit, have taken up professional snake catching as a trade to gain substantial economic benefits. Therefore, it is recommended that the relevant departments strictly crack down on and ban this destructive and predatory illegal behavior, and resolutely stop it. In this way, the sharp decline in the natural population of wild snakes can be reduced, in order to prevent severe damage to the ecological environment and cause even greater losses that harm future generations. Therefore, active and effective protection measures should be taken to promote the recovery and expansion of snake populations as quickly as possible in a short period of time, and restore the ecological balance necessary for humanity.
