Key Technical Points for Overwintering Management in Enclosed-Gully Rana Frog Farming
Rana frogs have the habit of hibernating and overwintering underwater. From late September each year to mid-to-late April of the following year, a period as long as 6 months, overwintering management in artificial enclosed-gully frog farming means, according to the living characteristics and needs of Rana frogs during this period, artificially selecting and creating suitable overwintering sites and water environments,

Key Technical Points for Winter Management of River Crab Pond Aquaculture
2015 was a relatively warm winter, with daytime temperatures basically staying above 10°C. A warm winter is relatively special for river crabs, as their living habits are greatly affected by temperature. This is mainly because river crabs begin feeding at 10°C and feed normally above 16°C. Therefore, under warm winter conditions, the activity capacity and feeding of river crabs are significantly enhanced. Overwintering is a foundation, and how to let river crabs overwinter healthily and smoothly will directly affect our aquaculture benefits in 2015. This article shares some communication with everyone on the key points of winter management of river crab ponds.

Tilapia Farming: A Detailed Guide to Overwintering and Broodstock Preservation Techniques in Greenhouses
Tilapia is a tropical fish with relatively poor cold resistance. Generally, when the water temperature drops to 12°C, tilapia will suffer frostbite or die. Oreochromis niloticus × O. aureus hybrids have relatively stronger cold resistance, but they still cannot overwinter in low-temperature environments for extended periods. In China, apart from Hainan, Taiwan, China, and parts of Yunnan and Guangdong provinces where natural overwintering is possible, tilapia in most regions cannot overwinter in natural conditions and must adopt corresponding overwintering and broodstock preservation measures to ensure the smooth overwintering of parents and fry.

High-yield breeding techniques for increasing wool production in Angora rabbits in winter
Scientific feeding. Angora rabbits are somewhat selective about feed. For example, they like leafy feed and sweet-tasting feed, and are especially fond of carrots and sulfur-containing feed. Where conditions permit, adding a small amount of sugar, earthworm powder, or vegetable oil to the daily ration can further improve its palatability.

Sharing Experience on Overwintering and Broodstock Preservation of Tilapia in Outdoor Ponds
Currently, most tilapia overwintering methods use indoor ponds, which require demanding conditions and allow only a limited number of overwintering fish. In order to further increase the number of overwintering fingerlings, the following introduces outdoor pond overwintering and broodstock preservation technology: 1. Overwintering facilities: outdoor pond, area 1-1.5 mu,

Overwintering Management Experience for Broodstock Breeding Ponds in Crayfish Aquaculture
Throughout the entire overwintering period, broodstock basically do not feed and consume a great deal of energy. Therefore, before overwintering, feeding must be intensified to strengthen the broodstock's constitution, store the necessary nutrients for safe overwintering, and increase the overwintering survival rate. When the water temperature drops below 10°C, broodstock basically enter burrows to overwinter and rarely emerge to activity. At this time, the water level should be appropriately raised to ensure there is water or moisture in the burrows, but the water depth must not exceed the burrow entrance; it should be slightly lower than the entrance. Otherwise, the broodstock will emerge from the burrows and choose new places to dig. Once the broodstock have basically entered their burrows, spread a thin layer of plant straw along the water's edge around the pond perimeter, such as rice straw, reeds, cattails, etc. First, to keep warm; second, to provide a hiding and overwintering place for the juvenile crayfish produced before the broodstock overwinter.

Key Points of Winter Fattening and Breeding Technology for Meat Donkeys
Donkeys belong to the herbivorous category of animals, and donkey meat is tender and delicious, a high-protein, low-fat health food. Donkeys have strong disease resistance, tolerate coarse feed, are easy to raise, easy to manage, and reproduce quickly; they can be kept either free-range or penned, and require little investment, making them very suitable for small-scale raising by farming households. Therefore, breeding

Sharing Experience on the Prevention and Treatment of Common Winter Diseases in Domestic Rabbits
Low winter temperatures are unfavorable for the reproduction of pathogenic microorganisms. Therefore, there are relatively fewer diseases. However, because heat preservation and warming measures are generally adopted in winter, people tend to focus on heat preservation and warming while easily neglecting ventilation and air exchange, which increases the content of harmful gases in the rabbit house,

How to Improve Farming Efficiency When Raising Chickens in Winter and Spring
During the alternation of winter and spring, the weather is cold and green fodder is scarce. To achieve high efficiency when raising chickens at this time, the following points must be followed. Keeping warm: Low temperatures have a very obvious effect on laying hens. You can appropriately increase stocking density, close doors and windows, hang straw curtains, and use stoves for heating.
