What are the common diseases of foxes and raccoon dogs during gestation and the whelping period?
Foxes and raccoon dogs have now entered the critical stage of gestation and whelping since the spring estrus and mating, and a series of changes have taken place in their physiological functions, making them extremely sensitive to external stimuli, so the incidence of disease is very high. Recently many readers have consulted us on this matter. In response, the editor has specially invited Professor Hua Shufang of the Institute of Special Animal and Plant Sciences, Chinese Academy of Agricultural Sciences, to give an introduction to the prevention and treatment of common diseases of foxes and raccoon dogs during gestation and the whelping and lactation period. 1. What are the manifestations of gastroenteritis during gestation and the whelping period, and how is it prevented and treated? Answer: During gestation and the whelping period, the

New Shiitake Mushroom Ground Cultivation Technology Helps Cultivation in High-Altitude Cold Mountain Areas
Shiitake mushroom is a temperature-variable fruiting fungus; when the day-night temperature difference exceeds 10°C, it grows well, yields high, produces large and thick-fleshed mushrooms of good quality. In high-altitude cold regions, the day-night temperature difference in spring and summer is large, often exceeding 10°C, making it suitable for cultivating shiitake mushrooms, with a per-mu yield of 3000-4000 kg. The ground cultivation technology for shiitake mushrooms in high-altitude cold mountain areas is a new cultivation model following ground cultivation and bag cultivation of shiitake mushrooms, and it is also a good project for mountain people to escape poverty and become prosperous. The main cultivation techniques are introduced as follows: Cultivation season and temperature. The general sowing period is from April 20 to May 10 each year

Bagging Technology for Eggplants and Melons Helps Improve Safety and Efficiency
For vegetables harvested all at once, such as celery, cabbage, Chinese cabbage, and rapeseed, you can follow the pre-harvest interval of the pesticide and stop applying it a certain period before harvest, so the product meets pollution-free requirements. But for eggplant-fruiting and melon vegetables harvested multiple times, it is very difficult to set a fixed period before harvest to stop applying pesticides, especially during the harvest period, when fruits affected by pests or diseases may be harvested and sold before the pesticide residue period has passed, causing quality to decline. In tomato and cucumber cultivation, fruit bagging

These practical techniques help late-sown wheat achieve high yields
Because late-sown wheat (wheat sown after mid-October, generally called late-sown wheat) is sown late, it is difficult to achieve full, strong and uniform seedlings, and thus difficult to obtain high yields. However, with proper management, a high yield is entirely possible. 1 Apply sufficient base fertilizer. Late-sown wheat needs 10-15 days from sowing to emergence, which shortens the pre-winter growth period and causes the seedlings to grow in the soil for too long and become weak. Late-sown wheat must be given sufficient base fertilizer, with 3500 kg of high-quality farmyard manure, 40-45 kg of ammonium sulfate, 50 kg of superphosphate and 10 kg of potash fertilizer per mu

How to Perform Manual Assistance During a Dog's Whelping
1. Key Points of Assisted Whelping Not all bitches can give birth smoothly without their owner's help. This is especially true of bitches of pure bloodline that have been overprotected, whose entire diet and daily life are specially cared for by their owners, making them highly dependent, even when giving birth. Especially for normally pampered bitches, during labor pains and after delivery they will not bite open the fetal membranes, causing the puppies to suffocate and die. So for the delicate Pomeranian, the owner must take extra care during whelping to help it give birth smoothly.

Feeding chickens with kombucha helps increase egg production
In the process of raising chickens, the author once used kombucha liquid to mix feed for laying hens and achieved obvious results. The laying rate reached over 95%, which was 15% higher than the original mixing with clean water, and the eggs laid were also larger than before. Preparation of kombucha liquid: Put an appropriate amount of tea leaves and white sugar into a teapot, then brew with boiling water. After it cools, use it as a culture medium to inoculate (soak) the kombucha starter. After 3 to 5 days, it becomes kombucha liquid. Mix it into the compound powder feed at a dosage of 2 milliliters per chicken per day and it can be fed. Using kombucha liquid

What are the precautions during the fox whelping period?
Most foxes give birth at night and in the early morning, and the whole birthing process usually takes 2-3 hours. After giving birth, most mother foxes eat the afterbirth and lick the mucus off the cubs' bodies. A few first-time mothers do not know how to care for their young and often do not eat the afterbirth. Fox cubs can nurse immediately after birth, and the lactation period is 55-60 days. Under normal nutritional conditions, most mother foxes care for their cubs attentively, but a few first-time mothers, those with no milk or insufficient milk, or those that have not finished giving birth (including stillborn cubs), or mother foxes with diseases, will

How to store pears in spring? Four methods to help you extend their shelf life
1. Chemical fumigation method. The fumigation method mainly prevents and controls diseases that invade the fruit. First, seal the pears with plastic film, then place a fumigant (such as acetaldehyde) inside the sealed plastic film so that the fumigant concentration inside the plastic film reaches 0.5% and is maintained for 180 minutes, or so that the fumigant concentration inside the plastic film reaches 1% and is maintained for 120 minutes. 2. Medicinal solution soaking method. This method mainly prevents pears from being infected by pathogens after harvest. Soak the pears in a 400-fold dilution of 4% Nongkang 120 fruit tree-specific solution for 50 minutes, then remove and air-dry, then package and store

What is the fresh-keeping principle for edible fungi? This article will help you understand it clearly
Fresh-keeping for edible fungi (theprincipleoffresh-keepingforediblefungi): Mushroom bodies separated from the culture substrate still have vitality, and living organisms have resistance to adverse external environments and microbial infection. However, the stronger the life activity, the faster the rate of freshness decline. Therefore, without destroying the normal physiological functions of the organism, by controlling various factors that affect the physiological and biochemical changes of fresh mushroom products, the life activity of the mushroom body can be kept as low as

How to reduce contamination in edible mushroom inoculation? Five practical methods to help you solve it
Autumn and winter are the golden seasons for producing edible mushrooms, but every year, inoculation contamination causes economic losses of around 20% for mushroom growers. Using the following 5 methods can reduce the inoculation contamination rate. 1. Bottled fermented material: Fill fermented material 1 to 2 cm deep above the culture medium at 4 cm from the bottle mouth, then sterilize. Its advantages are that contaminating bacteria are less likely to infect the culture medium, and the spawn age is consistent. 2. Wheat grain germination method: Let wheat grains germinate before bottling and sterilizing. That is, let the wheat grains used for spawn germinate all at once, with sprouts 1 to 2 times the length of the wheat grains, then fully sun-dry and store. One day before making the spawn, soak the wheat grains for 12 hours and directly bottle and sterilize. Its advantages are that the process of boiling the wheat grains is omitted, mycelium grows quickly, and there are fewer contaminating bacteria. The contamination rate is 2% to 3%.
