Treatment of chicken vitamin B1 deficiency

Clinical symptoms

At the beginning of the disease, the chicks have reduced feeding, and they are depressed and stand still. Closed eyes and lethargy, two wings drooping, legs soft and weak, walking inflexible, good lying. Two to three days after the onset of the disease, the two feet were slightly paralyzed, unable to stand, difficulty walking and gradually paralyzed. The acupuncture toe and other parts are painless, and the two legs are everted, or they are "forked" in tandem, and some of the head and neck are up or backwards and are "star-shaped". The young child can not stand and walk, lying on the ground, and finally died due to inability to eat. Anatomical lesions except the liver was pale yellow and gallbladder bloated and individual chicks had bleeding points in the digestive tract mucosa, and no visible lesions were visible in other organs.

Laboratory inspection

(1) General pathogen examination, aseptic collection of heart, blood, liver, spleen, kidney, lung and other internal organs of the dead chicks. After smear microscopy, no pathogens were found, and no pathogens were grown in the medium.

(2) Marek's disease follicle agar diffusion test, according to the two legs of the young child, the feather sac of 20 young birds with typical symptoms was made into a feather sac leachate, and the test result was negative.

treatment method

After the onset of the chicks, the breeder treated with oxytetracycline and penicillin, the effect was poor. After that, vitamin B1 injection was combined with other drugs to achieve satisfactory results. Pick out 30 chickens with reduced food intake, soft legs and unstable standing, divided into two groups. The first group of 15 feathers, intramuscular injection of vitamin B1 injection, oral cod liver oil pills, calcium tablets, and fed to vegetables. The second group of 15 animals was a control group without drugs. The treated chicks began to walk from the third day and walked until the fifth day, and the diet, standing and walking returned to normal. In the control group, the symptoms of the chicks became more serious, and they all died within 3 to 5 days. After that, the remaining chicks were fed with vitamin B1 (mixed with powder into the feed) and green vegetables. After 8 days, the chicks recovered.

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Specification

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
