What is Lasote?
Lasot is a kind of vaccine, which can be both homogeneous and fine-grained, produced from the virus-containing extra-embryonic fluid of chicken embryos. Available in the form of tablets pink-cream or light brown in color, packaged in glass bottles, as well as in the form of ampoules for 500 doses. Bottles are packed in 1500 and 3000 doses. When water is added, the tablet dissolves very quickly.
It is important to remember that Lasot does not have a healing effect and is only a preventive vaccine for pigeons and other bird species. When buying vials, be sure to pay attention to the labels. They must bear the name of the drug (Lasota), the date of manufacture and the batch number. Always pay attention to the expiration date and method of saving funds. This will help protect yourself from a useless drug, and thus protect your flock of birds.
The first and main effect of the drug is to prevent the onset of Newcastle disease. It is used in all cases, regardless of the type of farm. In addition to the main treating component, Lasot vaccine also has a protective base of peptone and skimmed milk.
After the introduction of the vaccine in pigeons and other birds for 8-14 days will form immunity to the causative agent of the disease. One time vaccination is enough for 3 months, after which the vaccination procedure must be repeated. Immunization occurs in all species of pigeons, regardless of the breed.
When and how is medicine applied to pigeons?
For vaccination of pigeons, Lasotha is suitable with a specific biological activity. To do this, pay attention to the inscriptions, where 8.5 lg (not less) EID per 50 / ml should be indicated. For the prevention of this drug is used only for healthy birds, regardless of the species, breed and period of molting. During the vaccination period, and this is 4 days before and 5 after the bird cannot be given any additional antibiotics. Including under the taboo also sulfanilamide and nitrofuran preparations fall.
In successful dovecot, that is, taking into account all sanitary and hygienic standards and where the bird is healthy, vaccination is carried out at the age of 15-20, 45-60, 140-160 days, after every 6 months. But in troubled poultry houses start from 10-15 days, then in 40-55, 120-140 days. These terms can vary depending on the state of immunity of their birds. But in any case, the result of Lasote's action should be checked in 14-21 days by examining the serum in HGS. To do this, examine 20 blood samples of birds.
If you received offspring from previously unvaccinated pigeons, then Lasotu chicks are given at the age of the first 5 days. After 21 days, be sure to repeat the course. In small dovecote birds can be vaccinated by drinking the drug with water or aerosol. But in large adverse dovecote most often used aerosol and intranasal method. For the latter method, the vaccine is diluted in boiled water (0.1 ml per 100 ml), and instilled with a pipette into the nose.
You can also spray the Lasote vaccine with a spray directly on the birds. To dilute the vaccine for feeding the young, a dose of 5 ml per 500 ml is used; for adult birds, 10 ml per 1000 ml. Give diluted Lasot in the morning two days in a row. At the same time 4 hours before watering and 2 after the pigeons can not be fed.
