Spring pig farming: pay attention to preventing vitamin deficiencies
Vitamin A deficiency: use 20 grams of pine needles, crush them for juice or boil them for juice, mix into the feed and give once, once a day, for several days in a row; you can also feed more carrots, silage and other feed rich in vitamin A. Vitamin B deficiency: when preparing daily feed, pay attention to fully supplying bran, silage, sprouted feed and others rich in vitamin B. If corn is used as feed for a long time, it can cause niacin deficiency. The amount of corn in the feed should be reduced and bran, silage, sprouted feed and juicy tuber feed should be increased.

Things to note when raising piglets in spring and summer, farmers should grasp them in advance
First, pay attention to temperature changes. In spring and summer, temperatures vary greatly, there is a lot of rain, and humidity is relatively high. Pigs prefer a dry environment, have little fat tissue, and piglets are prone to feeling cold. Therefore, the temperature inside the shed and the dry environment of the pen should be maintained. Second, pay attention to increasing protein feed. Especially for piglets that have undergone long-distance transport, due to stimulation such as wind-cold and the bumping of vehicles and boats, some piglets develop dysentery and diarrhea, reduced appetite, and weight loss. In addition to doing a good job of keeping the pen dry and warm, nutrition should also be supplemented in a timely manner.

Four key points for fish farming at the start of spring
1. Fertilization: In early spring, when the pond water temperature stabilizes at 8°C to 10°C, start applying additional fertilizer to cultivate natural food organisms in the water. The amount of fertilizer should be determined based on the fertility of the water and the quality of the fertilizer. Generally, apply 60 to 90 kg of human and animal manure per mu, or 100 to 150 kg of livestock manure. If chemical fertilizer is used, follow a nitrogen-to-phosphorus-to-potassium ratio of 1:1:0.5. When applying, first crush it, mix it with water, and splash it evenly over the entire pond. The total amount per mu is 3 to 7 kg, with each application spaced 5 to 10 days apart. Keep the pond water a yellowish-brown or yellow

Precautions for Spring Transport and Stocking of Fish Fry
Spring returns to the earth, water temperatures gradually rise, and it is once again the best time of year for transporting aquatic fry and fingerlings. During this period, because water temperatures are relatively low, fish are less active, and at the same time their bodies are firm and scales tight, so they are less likely to be injured during transport, which can increase the survival rate of spring stocking of fingerlings. There are many precautions in the spring transport and spring stocking of fingerlings, and fishermen friends are reminded to pay attention to them. 1. Pond disinfection should be carried out after removing excess sludge from the pond, reinforcing the pond embankment, and clearing the inlet and drainage ditches. Generally, for a dry pond, use about 200kg of quicklime per mu, slake it into a slurry, and

How to Prevent and Control Common Diseases in Pigs in Winter and Spring
This disease is an infectious disease of piglets caused by Salmonella. Piglets aged 1-4 months have high morbidity and mortality rates. The disease occurs in endemic or sporadic form, often in cold, changeable weather and rainy seasons. Poor environmental hygiene and reduced resistance of piglets can induce this disease. Symptoms and lesions: In the initial acute onset, it is similar to swine fever and requires comprehensive judgment combined with other examinations. The typical symptom is persistent diarrhea with a chronic course, and some piglets also show pneumonia symptoms. Lesions: Acute cases often die of shock, with purple congestion at the extremities and systemic septic

What are the key techniques for assisting ewes at lambing in spring
Every year in February-March, it is the peak season for ewes giving birth. To assist ewes at lambing, you need to master four key points: 1. Prenatal preparation. At this time the weather is turning warm but still cold, so before the ewe lambs, a lambing room must be prepared, with the temperature kept above 5°C, and disinfected with 2%-4% Lysol or 15%-20% wood ash water. The floor of the lambing room should be covered with dry grass or sand to keep it dry. At the same time, some disinfectants (such as alcohol, iodine tincture, etc.) and other tools should be properly prepared. 2. Normal delivery. When the ewe gives birth, the lamb first shows its two front

Things to Keep in Mind When Selecting Fish Fingerlings in Winter and Spring
1. Pay attention to whether the fingerlings are uniform. If the fingerlings in the same pond vary in size, have relatively straight belly lines, thin and elongated tails, and slender bodies, then after being placed in a fish cage for 30 minutes they will show weak, sluggish movement, and some may even show symptoms of disease. Such fish cannot be stocked into ponds, nor are they suitable for long-distance transport; you may reduce the stocking density or move them to fertilized water for rearing. If they are indeed diseased, timely treatment is also needed. 2. Pay attention to the body length of the fingerlings. Whenever seining exercise is carried out, the fingerlings jump vigorously

How to prevent spring sheep blindness? These preventive measures must be taken well
Sheep that eat the roots of the toxic daylily (Hemerocallis minor) will suffer poisoning. The clinical signs are characterized by blindness in both eyes, dilated pupils, bladder paralysis with urine retention, and general paralysis, which people call "blindness disease". In early spring, when pasture grass is scarce between seasons and the daylily is sprouting, grazing sheep often become poisoned after eating it, and generally die after 2 to 4 days. Mildly poisoned animals can recover, but those with blindness in both eyes and dilated pupils cannot recover. For this disease, there is currently no effective antidote, and the main approach is to carry out prevention well.

How to keep turtles safe through early spring? Key points for turtle care management
In early spring, turtles have just woken from hibernation and are very weak in activity. In addition, temperatures during this period are unstable, often fluctuating between high and low, making it a critical time for turtle care. So how can you care for turtles well during this period? (1) According to the turtle's physical condition, if heating is needed, raise the water temperature to about 25°C. (2) For feeding, follow the principle of small amounts and high quality. The amount for the first feeding should not be too much; 1% of the turtle's body weight is suitable, and feed twice a week. (3) When changing the water, the temperature difference between the new and old water should not exceed 5°C,
