Postpartum hypocalcemia in female dogs should not be ignored, and dog owners need to take it seriously
Postpartum hypocalcemia in female dogs, also known as postpartum eclampsia, postpartum tetany or lactation eclampsia, is a serious metabolic disorder in female dogs after giving birth. This disease is mainly characterized by hypocalcemia and muscle tonic spasms caused by abnormal excitation of motor nerves, accompanied by symptoms such as increased respiratory rate. This disease is paroxysmal and mostly occurs in small dogs or medium-sized high-yielding female dogs 10 to 20 days after delivery. At present, domestic techniques for diagnosing and treating this disease are relatively mature, and the treatment results are also relatively satisfactory. The basic approach is symptomatic treatment and calcium supplementation. The author, while treating 5 cases

What should be noted when giving injections to a sick turtle?
For captive-bred turtles that fall ill, treatment methods such as oral medication, injections, applying medicine, or even medicated baths can be used. Among these, injecting the medicinal solution directly into the turtle's body works fastest and most effectively. However, turtles have a shell for protection and more bone than flesh, so the following points must be noted when injecting a turtle, otherwise it is easy to cause harm to the turtle. 1. Choose the correct injection site. The leg muscles of the turtle's front and hind limbs are relatively plump, so intramuscular injections are generally given there. When injecting, the needle should preferably enter at a 45° angle to the limb; too large an angle will damage the fascia or bone

Drying ponds in winter has many benefits, and farmers should pay attention to this management practice
During a recent visit to rural areas of Xingyang in our province, the author found that many fishermen friends rush to disinfect and remove debris from their fish ponds right after selling their marketable fish, and then stock fingerlings in matching proportions. They believe this allows the fingerlings to adapt to the pond environment sooner, so they can start feeding and growing earlier in spring. Actually, this is not the case. It would be better to use the winter to expose and dry the fish pond, especially aged ponds, through alternate freezing and sun-drying. In aged fish ponds, fertilizer and feed residues, fish feces, sediment and impurities accumulate over time, and various pathogenic microorganisms multiply in large numbers, causing the ponds to age further and directly affecting

What should be noted when advancing the cotton sowing date?
Can the cotton sowing date really be advanced? Based on many years of cotton sowing practice, the lessons in this regard are very profound. It is true that using plastic film mulching for nutrient-pot seedling raising can also allow sowing in mid-to-late March and produce cotton seedlings in early April, and large-scale demonstrations have been carried out in production, but the result is that management is very difficult, and it is also hard to ensure full stands and strong seedlings. First, cold waves are frequent in early to mid-April, temperature fluctuations are large, north winds occur many times, and it is very difficult to judge when to uncover and cover the seedbed film; second, if continuous rainy weather occurs, it is difficult to ventilate the cotton seedlings on the seedbed, which very easily leads to spindly seedlings and causes cotton seedlings to lodge; third, low temperature and rain also easily induce diseases such as damping-off, anthracnose, and seedling blight, causing patches of dead seedlings in the seedbed; fourth, early sowing prolongs the seedling age of cotton seedlings, forcing them to be transplanted into the field too early. When early-transplanted cotton seedlings encounter cold waves, missing plants and broken rows often result from dead seedlings, generally 10%-20% missing plants, and in severe cases 30%-50% missing plants. In recent years, many new varieties have been introduced in cotton production, especially hybrid insect-resistant cotton, which is relatively expensive. If the area of missing plants is too large, it will not only cause economic losses, but also make it difficult to achieve one sowing, one transplanting, and one full stand of cotton. The planned cotton field area often cannot be realized, and it is even harder to ensure that excellent cotton seed is planted to achieve a high and bumper harvest.

What preparatory work should be done before sowing cotton?
I. Do a good job of pre-sowing preparation. Land preparation: for directly sown cotton fields, timely harrowing and smoothing should be done during the suitable moisture period to preserve soil moisture, so that the topsoil is loose and the subsoil is firm. 1. Deep plowing and land preparation: the plowing time for cotton fields can be divided into winter plowing and spring plowing, and winter plowing is better than spring plowing. Winter plowing should be deeper, generally 20-30 cm. Spring plowing should be appropriately shallower, generally 13-16 cm is suitable; after plowing, the land should be finely prepared, so that the topsoil is loose and the subsoil is firm, the soil is loose, and water is stored and moisture is preserved. 2. Apply sufficient base fertilizer: applying sufficient base fertilizer and building up soil fertility is the foundation for high cotton yields. The amount of base fertilizer applied should be determined according to yield, soil fertility and fertilizer

What should I do if my impatiens (touch-me-not) gets mosaic virus disease?
Impatiens mosaic virus disease occurs relatively commonly in Shanghai, Guangzhou, Nanning and other places in China. [Pathogen] Cucumber mosaic virus (CMV), see Gladiolus virus disease for details. [Symptoms] The new leaves at the top of the plant develop mosaic patterns, sometimes deformed; in severe cases, the shoot tips become rosette-like and the plant is stunted. [Occurrence pattern and epidemic characteristics] This virus has a very wide host range, and there are more than 60 species of aphids that transmit it, with the main vectors being Myzus persicae, Aphis gossypii, and corn leaf aphid (Aphismaidis), etc.

Common misconceptions about dog ownership, and the mistakes owners should avoid
In recent years, companion animals have brought joy to more and more families. But did you know? Some of our taken-for-granted dog-keeping habits not only harm the dogs but may also bring some conflicts to society. Only by combining a strong sense of responsibility with scientific care can companion animals thrive. Below are some misconceptions and the correct approaches. 1. Taking the dog out without a leash, letting it run and play freely - it is free, and I have less trouble. Correct approach: if a dog suddenly runs out, even people who like animals cannot help but be startled, let alone those who know nothing about canine behavior. Getting lost, poisoning, fights, car accidents... a small leash can prevent many tragedies. Once danger occurs, with a gentle pull it is under your protection, and those who like dogs but are somewhat afraid are also more willing to get close to it.

Garlic sowing time should not be advanced; mastering the right sowing time is key
Garlic prefers cool conditions and has a dormant characteristic. If sown too early, the emergence time is prolonged, and after emergence the temperature cannot drop, so the leaves tend to turn yellow and form weak seedlings, ultimately affecting quality and yield. If sown too late, before overwintering the seedlings are small and have weak cold resistance, and the following year they easily form large-headed garlic. By summarizing the experience of growers and the author's trials, it is recommended that garlic in our province be sown in late September. At this time the garlic dormancy period has passed, and 13 days after sowing the seedlings can emerge uniformly. After emergence, the seedlings are in the cool autumn season, which is favorable for their growth, and before overwintering they can grow enough 6 leaves, with enhanced cold resistance.

What issues should be noted when harvesting sweet potatoes?
Sweet potato is a vegetatively propagated vegetative body, with no obvious maturity standard or harvest period, but harvesting too early or too late affects the yield, seed retention, storage, processing and utilization, and crop rotation of sweet potatoes. Harvesting too early will significantly reduce the yield of sweet potatoes; harvesting too late, sweet potatoes are often affected by low-temperature chilling injury, are not resistant to storage, and the drying rate declines. Therefore, sweet potatoes must be harvested at the right time. The suitable harvest period for sweet potatoes should be determined according to climatic conditions, safe storage time, and the arrangement of the following crop. When the ground temperature is around 18°C, the weight increase of sweet potatoes is very small; when the ground temperature is

What key steps should be taken for autumn fish fry management
Pond clearing. Transfer the fish fry to a pond that has been cleared and disinfected for rearing. If water sources and pond rotation are difficult, all the fish fry can be transferred out for temporary holding, then the original pond disinfected with 75 kg to 100 kg of quicklime per mu, and the water fertilized by conventional methods; after the chemical effect has dissipated, transfer the fish fry back. Separate rearing. Adjust and separate the fish fry by different sizes so that the fry stocked in the same pond are of uniform size. Larger fry have a big appetite and a strong ability to compete for food; if small-sized fry are stocked in the same pond, the small fish will decline in condition because they cannot get enough feed.
