In the winter and spring cold season, chickens are prone to disorders of calcium and phosphorus metabolism due to lack of light and lack of calcium and phosphorus in the feed, causing abnormal bone tissue growth. This nutrient disease is called rickets in adult chickens and rickets in chicks. The diseased chickens are mainly characterized by poor development, loss of appetite, feathery hair, and keel changes. The joints between the soft ribs and hard ribs are round-shaped hard segments. The chest is flat and flat, protruding to both sides, and the mouth is soft, like an eraser, and can be bent. Foraging difficulties. The chickens can't stand on both feet and most of them lie on their backs. The chicks are curved or X-shaped. The spine is bent and the chickens are weak. The laying rate of the laying hens is reduced, the shells are thinned, and soft shell eggs are then produced. The thin eggs are thin. The boundaries between egg white and egg yolk are unclear.
In order to ensure the balance of calcium and phosphorus metabolism in winter chickens, the following points should be achieved: 1. According to the nutritional standards of chickens to prepare diets, give sufficient calcium, phosphorus and vitamin D, the best condition to use full-price compound feed, in order to ensure the chicken calcium and phosphorus needs. 2. Giving chickens plenty of sunlight (ineffective sunlight passing through ordinary glass), usually 16 hours a day is appropriate for sunshine, and the lack of sunshine can be replaced by the available electric lighting, and the chickens can be sun-bathed on the beach conditionally. Closed-type chicken farms should strengthen the irradiation of fluorescent lamps. It is advisable to increase the light for 10 minutes every week, keep the time constant, and supplement the gravel at the same time to improve the chicken's digestibility of feed. 3. Appropriate amounts of green feed, silage, and other vitamin-rich feeds such as cabbage leaves, carrots, and yam leaves.
If diseased chickens are found, the proportion of calcium and phosphorus in their diets should be promptly adjusted according to the nutritional standards, and additives should be added at the same time to increase the content of various minerals and vitamins in the diet. In particular, attention should be paid to vitamin D or cod liver oil supplementation. Promote the absorption of calcium and phosphorus in chickens. Under normal circumstances, add vitamin D2000 international unit per kilogram of feed, each chicken can be fed with 1 to 2 ml of cod liver oil daily. Severe illness can be subcutaneous injection of vitamin D injection, per kilogram of body weight daily 6000 ~ 10,000 international units, repeated every 3 to 5 days, usually 2 to 3 times can be effective, such as the use of oral calcium better.
The function of Syringe set mainly contains sealing function, tunnel permeability, tensile strength, puncture performance, degree of coordination, particulate contamination, reducing substances, metal ions, ph, ethylene oxide residue, sterility, bacterial endotoxin, cytotoxicity, sensitization, intradermal reaction, hemolysis, acute systemic toxicity, etc.
A mixing system sterile Medicine Mixer (powder and liquid ) is a device that mixes powder and injection before injecting the drug into the patient.But traditional booster injection infusion dispensing still exist, need medicine soluble medicine, when dispensing, repeated shocks and mixed extraction liquid, in the process of repeated puncture easy to produce plastic particles, particles stopper is getting into the human body easily blocked blood vessels, granulation, some problems of inflammation, and the ward of bacteria, viruses, repeatedly extracting liquid easy to carry the virus in the air, infusion to the solution of the problem.
