Why should sheep drink enough warm water in winter and spring?
In winter and spring, because the temperature is relatively low, if sheep are given cold water or even water with ice particles, they are unwilling to drink it, which will cause insufficient water intake. This not only slows down the digestion of sheep feed, blocks metabolism in the body, and reduces body condition, but also causes various diseases. Therefore, in production, drinking water conditions must be created for sheep to ensure clean and sufficient drinking water. Drinking water temperature: if the water the sheep drink is too low in temperature, the water will absorb the heat that the sheep itself converts from feed, which will reduce feed utilization. Therefore, in winter and spring, the best drinking water temperature for sheep is 20-30°C

Releasing fish fry in early spring requires care; keep these precautions in mind
Fish fry quality For fish fry of the same species and same age, the specifications should be uniform, with little difference in body length and body weight, thick back muscles, bright color, intact scales and fin rays, normal activity, and strong upstream-swimming ability. After being taken out of the water and placed in a basin, the gill covers should not open, the tail should not bend, and the fish should keep jumping, with no wounds or parasites on the body surface. Fish fry disinfection Some farmers do not disinfect fish fry at all when releasing them, resulting in a high disease rate, and drug treatment is not ideal. In fact, as long as fish fry disinfection is done well, disease prevention can often achieve twice the result with half the effort

What nutritional points should be noted when raising piglets in spring and summer?
From March to June, temperatures gradually rise, which is exactly a favorable period for developing pig production. Four issues should be noted in feeding. First, pay attention to temperature changes. In spring and summer, temperatures vary greatly, there is more 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, because they are stimulated by wind, cold, and the bumps of vehicles and boats, some piglets

Key Points for Pre-Farrowing Preparation of Sows in Winter and Spring
In winter and spring, the weather is cold, so wind protection and warmth retention must be well managed. It is best to set up a dedicated farrowing room for the sow. The farrowing room should be warm and dry, with humidity kept at 65%-75%, comfortable and quiet, with plenty of sunlight and fresh air, and a temperature maintained at 22-23°C. For sows in good body condition with well-developed udders, feed should be reduced 3-5 days before farrowing, gradually decreasing to 1/2 or 1/3 of the feeding level during gestation, and feeding of green, juicy feed should be stopped. For those sows in poor body condition and with underdeveloped udders, not only should feed not be reduced before farrowing, but some feed rich in protein and vitamins should also be added.

How to prevent swine influenza in winter and spring?
Swine influenza (swine flu for short) is an acute, highly contagious respiratory infectious disease caused by a virus. The disease has a sudden onset and spreads rapidly, with a morbidity rate in pig herds as high as 100% and a low mortality rate. The disease is a zoonotic infectious disease. During an outbreak, the spread of the virus should be avoided as much as possible, and attention should be paid to protecting both keepers and veterinarians. (1) Epidemiological characteristics: Swine influenza occurs mostly in late autumn, severe winter and early spring. Diseased pigs, latently infected pigs and chronic virus-carrying pigs are the sources of infection. The virus persists

Bag-disinfection method for fish fry and fingerlings stocked in spring
"Bag disinfection" of fish fry and fingerlings is a new disinfection method summarized and used by fish farmers in recent years. Its advantages are that it is simple and convenient, costs little, can reduce fish diseases, and gives a high survival rate. The method is: 1. Operation (1) Place the nylon bag holding the fish fry and fingerlings at the pond edge (untie the bag opening), with the water level inside the bag level with that outside. (2) Pour the medicinal solution into the bag and shake well, and observe the activity of the fish fry and fingerlings; after the disinfection time is completed, put them into the pond. 2. Drug preparation and soaking time (1) 3%-5% salt solution, soak the fish fry and fingerlings for 20 minutes, can prevent and treat bacterial diseases

How to fatten thin cattle in spring? Master these key points
1. Choose good cattle for fattening The key to choosing good cattle for fattening lies in discovering the fattening potential of thin cattle. Thin cattle caused by poor feeding management, low-quality feed, or excessive labor can be chosen as the first choice. Never buy sick cattle that are too old, suffer from digestive tract diseases or infectious diseases, and are extremely weak. 2. Build good pens Create a quiet, comfortable, and clean living environment for thin cattle to minimize stress responses. 3. Group reasonably: Group newly purchased thin cattle by age, sex, and nutritional status. This not only

How to use medication for chicken respiratory diseases in winter and spring? Farming experience sharing
There are many causes of chicken respiratory diseases, which can be broadly divided into non-infectious causes and infectious causes. Every year starting from Cold Dew, the temperature difference between day and night increases, and most farmers reduce ventilation time to keep warm. Coupled with factors such as unreasonable chicken coop design and unreasonable vaccine immunization, respiratory diseases have long plagued the majority of farmers. Analysis of disease causes: Feeding management - poor ventilation in chicken coops. The concentration of harmful gases such as carbon dioxide exhaled by chickens, ammonia and hydrogen sulfide produced by feces, and carbon monoxide produced by incomplete coal combustion rises, while oxygen concentration decreases. Chickens kept in such an environment for a long time will suffer damage to their respiratory systems. Ammonia and hydrogen sulfide gases can cause inflammation of the conjunctiva and tracheal mucosa of chickens, making it easy for pathogens to invade the respiratory system and cause disease; carbon monoxide can cause poisoning in chickens; dust caused by dry litter carries large amounts of pathogenic bacteria such as E. coli, and when the concentration is high or the body's resistance decreases, it is easy to cause colibacillosis; if moldy litter is used, large amounts of mold spores are dispersed in the air, and after being inhaled by chickens, they cause aspergillosis in chickens. Environmental factors such as excessive stocking density in chicken coops and ambient temperatures that are too high or too low can all interact with infectious respiratory pathogens, aggravating the symptoms of respiratory diseases.

What are the common methods for preventing and treating diseases in sheep raised in spring?
Acute bloat: Because sheep are fed hay for a long time during winter housing, they are prone to overeating when they occasionally eat green grass in spring. The green grass ferments acutely in the stomach, producing a large amount of gas, which expands the rumen. If rescue is not timely or the rescue method is improper, it can cause the sheep to die. Rescue method: insert a section of willow stick into the sheep's mouth, tie both ends with rope to the sheep's head, let the sheep chew, and at the same time massage its left flank with your hand to help release the gas. You can also peel the paper off 5~10 cigarettes, divide the tobacco shreds into two portions and stuff them into the sheep's mouth; mild cases recover 1 hour after eating. You can also use
