It turns out that so many reasons can lead to leg disease in chickens.
1. Vitamin or trace element deficiency (1) when vitamin B1 is deficient, the sick chicken legs are soft and will not stand, lie down and look up at the stars. (2) when vitamin B2 was deficient, the tibia of the diseased chicken was dysplastic, the joint was enlarged, the claws were curled, and the hocks landed. Some legs spread apart, or one leg forward, one leg backward, similar to the symptoms of Marek's disease.

Ecological chicken breeding 6 points
1. Site selection: generally choose woodland, tea garden, orchard and hillside land. Natural forest is the best forest land, artificial economic forest is next to natural forest land. Hillsides require stable slope potential, leeward sunny, sufficient water. There is no big pollution source around the chicken farm, and it is more than 1 km away from residential areas, hospitals and slaughterhouses. 2. Select breeds: egg-meat dual-purpose chicken breeds, male chicks of egg chickens and rural grass chickens can be used as ecological chicken breeds. 3.

Analysis of factors affecting coloring of Sanhuang Chicken and its existing problems
In recent years, with the development of domestic poultry industry and the continuous improvement of people's living standards, consumers are becoming more and more picky about the consumption of meat, and people in East China have a special preference for Sanhuang chicken. In fact, the yellow deposited on the shank and subcutaneous fat of chicken feet is lutein, which is the general name of a kind of natural pigment. Because the chicken cannot synthesize lutein itself, the lutein that exists in the chicken comes from feed. So, what is the reason for the difference in chicken coloring? Let's analyze them one by one.

Quarantine and treatment of Porcine Toxoplasma gondii
Porcine toxoplasmosis is a zoonotic infectious disease caused by Toxoplasma gondii. It is most common in pigs and can be caused by traumatic contact or eating raw meat infected with the disease. therefore, it is of great significance to ensure the development of aquaculture and human health to do a good job in pre-slaughter quarantine and post-mortem inspection of Toxoplasma gondii in designated slaughterhouses. 1 Pigs with toxoplasmosis were quarantined before slaughter, with a temperature rise of 41 to 42 ℃, loss of appetite or loss of appetite, runny nose, cough or dyspnea, anemia, conjunctival congestion

Improve sow's summer anestrus
To do a good job of sow reproduction is an important link in the development of pig industry and pig income. In general, 28 ~ 35 days after parturition, sows will be in estrus naturally within 3 ~ 5 days. But in summer and autumn, pigs are not easy to be in estrus. In order to make sows normal estrus after weaning, the following measures can be taken. Feeding lactating sows with high temperature in summer, fear of heat, decreased appetite and poor body condition in weightlessness are the main reasons for sows not to be in estrus. Therefore, it is necessary to adjust as soon as possible.

Methods to prevent epidemic diarrhea in pigs
To prevent porcine epidemic diarrhea, attenuated or inactivated vaccine against porcine epidemic diarrhea should be vaccinated in advance, and 1 ml of attenuated porcine transmissible gastroenteritis vaccine should be injected intramuscularly and intranasally 45 and 15 days before delivery in sows. There is no vaccine against rotavirus disease. after diseased pigs are found, they should be isolated as soon as possible. 5%-10% glucose saline is injected intravenously and 3%-5% sodium bicarbonate is added. Piglets should stop breastfeeding and prepare glucose glycine solution for piglets to drink. The formula is: glucose 43.2

Processing technology of silverfish
Through processing, silverfish can be turned into high-quality fish products selling well in domestic and foreign markets, and the value of silverfish can be improved, so that the fishery can achieve high efficiency. Therefore, processing is an important part of silverfish and fishery. Because of the high protein content of silverfish, the catch is easy to deteriorate, so ice must be used to keep fresh in the process of acquisition and processing. At present, China's silverfish products are mainly processed into packaging in units of 1000 grams according to export standards, and also into 500g, 250g and 1 according to customer needs.

What problems should be paid attention to before fish farming
1, fish pond shape diversification: fish pond shape is often rectangular, pit type, in order to give full play to the three-dimensional benefits of aquaculture water. Single-mouth fish pond area is generally about 0.067 hectares (mu, the same below), pond depth 2.5-3 meters, aspect ratio 5:3, slope coefficient 2-3. Construction modeling can be easy first and then difficult, make some transitional fish ponds, such as "back" shape, high and low shape,"well" shape,"field" shape and so on, among which "back" shape fish pond is the most ideal transitional fish pond. 2. Timely supporting drainage and irrigation system: requirements

Causes and countermeasures of fish outbreak mortality
2. Bacterial and parasitic disease countermeasures for bacterial diseases, mainly to control the proliferation of pathogenic bacteria in fish pond water, the number of inhibition within the incidence of magnitude. This requires regular disinfection at ordinary times, disinfection once every 7~10 days with "Yujunjing,""Yujunjing No.2,""Junji" or strong chlorine essence to prevent excessive reproduction of pathogenic bacteria. After bacterial diseases occur, disinfect twice with disinfectant continuously, and mix feed with drugs such as "Xuexueping,""Jingbo Baoxueping,""Yubingkang,""Fisherman Bao" or "Jianyule"

Fish purchase and transportation
To get fish from a trusted source, verify that the dealer has adopted proper quarantine procedures to verify that the fish in the container looks healthy. Unhealthy fish may hang upside down in schools and be slow to respond to gentle tapping on aquatic plants (dealers disagree). Only a small number of fish are bred and sold locally, and most fish are airlifted over considerable distances, so the ultimate health of the fish depends to a large extent on the handling before and after transportation. Now airlines are quite good at handling fish.

There's something in the fish head that fights aging.
Fish brain contains fish oil, which is rich in highly unsaturated fatty acids, and its main ingredient is what we call "brain gold," said Wang Cunxin, a fish research expert and professor at the Institute of Oceanography of the Chinese Academy of Sciences. This is an essential nutrient for humans, mainly found in phospholipids in the brain, which can maintain, improve and improve brain function. If it is not taken enough, the baby's brain development process will be blocked. Therefore, there is a saying that eating more fish heads can make people smarter. Professor Wang said that other parts of the fish head are nutritious.

Eating habits of dace
Mud carp are omnivorous fish. four days after hatching, mud carp begin to feed on zooplankton, such as rotifers, copepods and small cladocera. After 10 days of hatching, the body length is more than 14 cm. In addition to eating zooplankton, they begin to feed on phytoplankton. After that, eat more and more phytoplankton, until about 40 days after the emergence, when the body length is more than 4 cm, they mainly eat phytoplankton. At the same time, mud carp like to lick and scrape the algae that grow on the surface of the underwater soil or rock. In addition, mud carp also ingest a small amount of zooplankton and organic crumbs.
