How to observe sick pigs? Master these methods to detect pig diseases early
Check the demeanor. Healthy pigs are spirited, with tails raised and swinging freely; sick pigs are listless, move slowly, prefer to lie still, and have drooping tails. Check the appetite. Healthy pigs have a strong appetite; sick pigs show a sudden loss of appetite, abnormal eating habits, or even stop eating. If a pig's appetite decreases and it drinks a lot of water, it is mostly a febrile disease. Check nasal discharge. Healthy pigs have no nasal discharge; if a pig has clear nasal discharge, it is mostly a wind-cold cold, thick and sticky nasal discharge indicates heat in the lungs, and nasal discharge containing foam indicates diseases such as pulmonary edema or chronic bronchitis. Check the feces. Heal

How to prevent and treat Newcastle disease in chickens? These methods you need to master
Newcastle disease in chickens, also called Asian fowl pest, commonly known as fowl plague, is a highly contagious, acute, and virulent infectious disease of chickens caused by Newcastle disease virus. It often presents as septicemia, with the main features being difficulty breathing, diarrhea, nervous system disorders, and hemorrhage of mucous membranes and serous membranes. I. Epidemiological characteristics: chickens of all breeds and ages can be infected, with young chickens and growing chickens being more susceptible, and older chickens over two years of age having reduced susceptibility. The main sources of infection for this disease are sick chickens and virus-carrying chickens; their secretions, feces, as well as contaminated feed, drinking water, non-susceptible wild birds, external parasites, humans and livestock can all transmit the pathogen. The main routes of transmission are the digestive tract and respiratory tract, and it can also invade the body through damaged skin and mucous membranes. It can occur in all four seasons. In non-immune areas or in flocks with low immunity, once a velogenic strain invades, it can spread rapidly, causing a devastating epidemic, with morbidity and mortality reaching over 90%. At present, in large and medium-sized @#@230@#@ farms, where flocks have a certain level of immunity, Newcastle disease mainly appears in an atypical form, which should be given attention.

Why is the golden-headed turtle called a masterpiece among turtles?
The golden-headed turtle, also known as the snake-eating turtle, is a specialty of China and originally lived in mountain streams south of the Yangtze River basin; it is now on the verge of extinction. The golden-headed turtle has a smooth, scale-free head, a short snout that does not protrude beyond the edge of the beak, an upper beak with a distinct notch, large eyes, a round and clearly visible tympanum, and a broad golden-yellow arc-shaped stripe behind the eye, hence the name "golden-headed turtle." The golden-headed turtle is a treasure among turtles; its meat is delicious and tastier than that of the golden coin turtle, rich in protein, vitamins and essential amino acids for the human body, and is a premium tonic. The plastron of the golden-headed turtle can be processed into many kinds of traditional Chinese patent medicines

How can the efficacy of fishery drugs be improved? These five methods must be mastered
Improve the binder The binder must be highly sticky, otherwise the drug is easily lost in the water. Standard wheat flour is a good binder material. For swallowing fish, it is best to make pelleted medicated bait or ball-shaped medicated bait for feeding. Add a feeding attractant Fish have a keen sense of smell; even if 1 gram of alanine is dissolved in 1 million liters of water, fish can still detect it. For example, if strongly aromatic Chinese herbal medicines such as star anise and Angelica dahurica are ground into fine powder as a feeding attractant, and mixed into fishery drugs at a ratio of 10%-20%, or added to roasted soybean powder, wheat flour, etc., all have obvious attractant

How to prevent empty and blighted rice grains? Master these technical measures
Empty and blighted rice grains refer to unfertilized empty grains and half-empty grains that fail to develop after fertilization, and this has a great impact on rice yield. Therefore, in rice production, in addition to striving for more panicles and larger panicles, it is also necessary to reduce empty and blighted grains, improve the seed-setting rate, and increase the 1000-grain weight in order to obtain high yields. At present, rice is in the grain-filling and ripening stage. To prevent the occurrence of empty and blighted rice grains and achieve the goal of high yield, comprehensive preventive measures must be taken. The specific measures are as follows: 1. Select varieties with good seed setting. Rice varieties differ in physiological morphology, and the seed-setting rate varies greatly.

Six key points to master for summer management of lilies
1. Fertilize according to seedling growth. After lilies are planted, they begin to emerge when the soil temperature reaches 14-16°C. Because lilies take a long time to emerge and consume a lot of nutrients, seedling fertilizer should be applied heavily. Apply 1000 kg of fully decomposed human and livestock manure or 20 kg of urea as a drench per 667 sq m. In early June, when lilies enter the early flowering stage, their underground bulbs grow faster. This period is critical for lily yield formation, and the fertilizer demand is large and concentrated, so a leaf-strengthening fertilizer should be applied as a top dressing. Apply 15 kg of urea per 667 sq m. Lilies have a preference for phosphorus

How to prevent and control lily anthracnose? These methods you need to master
Symptoms: Leaves develop round, pale yellow spots, with dark brown margins. On petals the spots are round and flax-colored. They occur mainly on the outer surface of the upper half of the scales, and also on the inner surface. Initially irregular, light brown spots appear, later becoming light blackish brown and slightly sunken, and finally the diseased area becomes almost black, with the tissue shriveling and dry-rotting. The spots can extend several layers deep into the scales, but the outermost scales are affected most severely. Flower buds on diseased bulbs abort, turning brown to black, or large numbers of small water-soaked round spots appear on the flowers, merging with each other into irregular brown patches

Six key points to master for garlic cultivation with plastic mulch
Garlic cultivation with plastic film mulch has a significant yield-increasing effect and very obvious economic benefits. During cultivation, attention should be paid to the following six aspects: Fine land preparation and fertilization: prepare the land carefully and increase the application of organic fertilizer, applying 5000-7500 kg of decomposed organic fertilizer per mu. For plastic film mulching, small raised beds are generally used, with a bed width of 70 cm and a bed spacing of 20 cm. Plant 4 rows per bed, with a row spacing of 15 cm and a plant spacing of 10 cm. For mulching with plastic film, generally sow first and then cover with film. The film should be covered tightly and pressed down firmly so that it fits closely against the ground with no gaps and no wrinkles. Any holes should be promptly plugged with soil.

How to store garlic? Master these five methods for easy preservation
1. Hanging storage method. When harvesting garlic, strictly select the garlic intended for hanging storage, removing heads that are too small, have rotten stems and leaves, are damaged, or have been exposed to moisture. Then spread them on the ground to dry until the stems and leaves become soft and yellow, and the outer skin of the garlic is dry. Finally, select 50 to 100 garlic heads of uniform size and braid them, hanging them under a cool, ventilated, rain-sheltered eaves to air-dry and store. 2. Pile storage method. After harvesting garlic, remove scattered cloves, insect-damaged, moldy, and injured heads, tie them into bundles of 50 to 100 heads, and
