The key techniques of raising Pelteobagrus fulvidraco
In order to cultivate Pelteobagrus fulvidraco, the key work is to do a good job in the prevention and control of diseases and insect pests. First, make preparations in winter. Both new and old ponds must be cleaned and sterilized before releasing seedlings. The old pond should remove too much silt and retain a silt layer of 10 cm thick. Every winter, the fish species go through the pool or adult fish out of the pond, drain the pond water, clean up the sludge at the bottom of the pond and trim the pond foundation, so that the pond is exposed and cracked. (1) clear the pond. ① dry pond first drain the pond water (or leave water 60.9%)

Technical measures for releasing fish fry in winter
As the saying goes, "in spring, the fry has a plague, and in winter, the fry is three points longer." Practice has proved that the Winter Solstice to the Beginning of Spring is the best time to release fish species. There are three reasons: first, at this time, the fish species are strong, the scales are tight, and the adaptability is strong. Second, the water temperature is low, the activity of fish is weak, and the survival rate is high in the process of fishing and stocking. The third is to avoid the trouble of overwintering in the pond, so that the fish species can be evacuated and refined earlier, so as to promote the growth of early spring. 1. Transformation of fish ponds. Make use of winter leisure to transform fish ponds, small ponds into large ponds, dead ponds into living ponds, shallow ponds

Determination of dosage of soft-shelled turtle
1. Determination of the dosage of drugs for external use (1) the concentration of drugs (ppm) was determined according to the safe concentration of a certain drug and the lethal concentration of the drug to pathogens. (2) accurately measure the volume of turtle pond or determine the volume of bath water. The calculation method of water volume is: water volume (m ^ 3) = area (m ^ 2) × average water depth (m). (3) calculate the dosage: dosage (g) = the concentration of the required drug (ppm, g / m ^ 3) × water volume (m ^ 3) 2.

A large number of fish die, is it lack of oxygen?
The epidemic season of tilapia hemorrhagic disease is long, and the epidemic season is from June to September. At the time of onset, the water temperature was more than 25 ℃. The morbidity and mortality rate is high. During the epidemic, the morbidity can reach 50% Murray 70%. It is reported that the mortality rate can reach 30% Mui 90%, or even be wiped out. The types of disease can be divided into acute and chronic. Acute morbidity and death often occur within a week, and chronic morbidity lasts as long as two or three weeks or even two months. The disease can occur in a wide range of water areas, including pond culture and reservoir cage culture. Symptoms: real

Experiment on early rearing of eel seedlings in greenhouse
At present, the cage culture of eel is concentrated in July, the survival rate is high and the risk of culture is low. However, the concentrated acquisition of Miaoyuan is less, the price is high, and the weight gain multiple is low. If the eel seedlings are purchased early and the temperature is unstable, the mortality rate of eel seedlings is high. How to solve this problem? We have carried out the experiment of early rearing of eel seedlings in greenhouse, and the results of the experiment are summarized as follows: first, test conditions 1. Test pool: the newly excavated water surface is 250m long, 4m wide, 1.5m deep and covers an area of 1000 square meters. The water source is the lake

Summer: safety measures for pregnant rabbits to spend the summer
In the hot summer, measures should be taken to ensure that pregnant rabbits spend the summer safely. First, pay attention to heat prevention and cooling. The suitable temperature for pregnant rabbits is 14-16 ℃. In summer, we should do a good job in preventing heat and cooling to prevent heat stress, resulting in premature delivery, miscarriage or stillbirth of pregnant rabbits. Keep the rabbit house cool and well ventilated, and the rabbit house will build an Arbor. Second, adjust the feed in time. Heat often results in a decrease in food intake of pregnant rabbits. It is necessary to adjust the feed in time, increase the proportion of protein and energy feed, and feed more green succulent feed when the feed intake is reduced.

Application of Liquor in sericulture
Liquor is fermented from grain or some fruits. It has bactericidal effect and is often used as a disinfection cleaner and preservative. At the same time, it is also a kind of traditional Chinese medicine, which can open the blood, lift the spirit, and act in medicine. It is known as "the length of a hundred medicines". Therefore, it is also widely used in sericulture to prevent disease and increase production. 1. Disinfect the egg surface. Soak the silkworm eggs in 60 degrees of liquor, take them out immediately after about 60 seconds, shake off the excess liquor, spread out the silkworm eggs and let them hatch. In this way, the ants can come out in advance, and the ants are one, the growth is robust and the disease is less. 2. Mulberry leaf surface

Deer feed with sodium humate to produce more antler.
According to the deer farm experiment of 597 Farm Agriculture and Forestry Company, using sodium humate as deer feed additive increased deer food and drink, exuberant metabolism, and provided sufficient nutrition for the growth of pilose antler. According to the experiment, each stag was fed 0.2 grams of compound sodium humate three times a day. Two hours before feeding, the solid compound sodium humate was diluted to 0.05% with a PH value of 6.5, and then fed with green feed for 70 consecutive days until the antler was collected. The results showed that the per unit yield of pilose antler was 575g in the test group and 490g in the control group, with an increase of 17%.

Technical measures to increase the yield of royal jelly
Increasing the yield of royal jelly is an important guarantee to improve the economic benefit of beekeeping. The following five technical measures should be taken to increase the output of royal jelly. 1. In honeybees, royal jelly is secreted by young bees and is the main food for queen bees and bee larvae. Therefore, in order to increase the yield of royal jelly, there must be more strong colonies of young bees, and the production of royal jelly must be adjusted in time. If there are only 6-7 frame-footed wasps, the high yield of royal jelly cannot be obtained. To this end, it is necessary to increase the number of youth.

Prevention and treatment of joint abscess of pigeon
The main reason for the occurrence of pigeon joint abscess is that it is caused by leg skin injury and infection caused by long-term feeding in rugged pigeon houses or rough pigeon cages with sharp thorns. It is common in ankle and elbow joints, and the incidence of adult pigeons is high. Symptoms: at the beginning of the disease, the pigeon can not walk well and even limp, the affected joints show red, swollen, hot, painful and inflammatory symptoms, and gradually increase and protrude, and touch it from hard swelling to soft swelling, there is a feeling of fluctuation, and there is pus outflow after incision. Abscess with long course of disease, local skin thickening, hard touch

How to produce high quality rabbit wool
Rabbit hair can be divided into three types: fine hair, coarse hair and two-type hair. Fine hair, also known as rabbit cashmere, has an average fineness of 12 to 14 microns, the shortest of the three types. There is a marked irregular bend. Because fine wool has good physical and chemical properties, its textile value is very high in the wool textile industry. Generally speaking, its price is also higher than the other two types. For this reason, mastering the production technology of rabbit cashmere and producing more fine hair is an effective means to improve the production efficiency of wool rabbits. 1. Understand the quality requirements of rabbit wool. Rabbit velvet should be pure white, all loose hair, no impurities.

The main equipment of deer house construction
1. Feeding equipment (1) Water supply equipment source, submersible pump, water tank, water pipe, drinking tank, etc. (2) in order to make deer drink warm water in winter, rectangular troughs or large iron pots made of iron plates can be fixed on the pot table for heating. The sink or water pot had better be located under the front wall, or at the lower end of the feed trough in the middle of the playground, or protruding a small part of the corridor, so that it can be fed and heated directly in the corridor, saving time, labor and safety. The sink is 2 meters long (through the wall, for two circles), 0.6 meters wide and 0.35 meters deep. Pots and stoves should be firm.
