Vaccination is a part of every program for managing poultry health. The goal is to expose birds to diseases that they can experience in a controlled and safe manner in the future. In this way, the birds own immune system provides a buffer against certain diseases when attacked at the shed.
Small flock holders will also only make up vaccine water buckets and dump them into drinking containers, which is not practical for larger flocks. There are three main types of delivery systems available for birds to be immunized via their drinking water: through header tank, medicine tank, or a dosing pump.
Water Quality and Stabilisers
Water quality, appropriate volumes and adequate availability are critical for good dispersal of the vaccines. It enables the survival of live vaccines in the water and all birds to be vaccinated equally. Residues of disinfectants from daily chlorination or recent equipment cleaning can always destroy the live vaccine and render it ineffective. When using well or ground water, minerals and other impurities present on pure groundwater can bind live organisms to the vaccine, preventing them from entering the appropriate tissues inside the pet.
Skim milk has historically been the normal approved commodity to be added to the water before applying the vaccine (at a rate of 30-50 ml of milk per liter of water-3-5 per cent). Because it stabilizes the water, the use of milk has many drawbacks: shelf life is quite short / it goes off in a few days; fresh skim milk on the farm on the day of vaccination is not easy to access; and it requires refrigeration.
In addition, milk in water at 3-5 per cent renders the water whitish gray, but only in large amounts. It is difficult to monitor the distribution of vaccines in the shed or flock, as it looks transparent in small volumes.
Commercial Blue Stabilisers
Traditional industrial stabilisers are a simple and cost-effective alternative to milk. Because you can see from hard water, they not only protect the vaccine against the harmful effects of free ions, but they also have a protective dye that indicates where the vaccine water is heading. The devices, feather or birds are without a mark. It helps the operator to see where the vaccine is being given, and also allows the operator to monitor the absorption of the chickens, with successfully vaccinated birds displaying a light dye on the tongue. A commercial stabilizer is also considerably cheaper than using milk, with long shelf-life and no need to cool down.
Direct on Chick Fonts
During the first days of the chick’s life it’s difficult to determine the optimal quantity of drinking water for vaccination. Many poultry operations already launch the chicks on their definitive drinkers, on nipple, bell or cup drinkers, whether they are in cage or in floors. Most chicks will generally adapt well to these systems as long as (1) the availability of drinking equipment is adequate for all birds to have a reasonable chance of drinking, (2) the source of water is clearly evident to young birds, (3) it is adequately dispersed, and (4) at the appropriate height. Furthermore, the cloud based poultry software approach will help you expand your product.
Most operations on poultry will have one or more header tanks per shelter. Such header tanks are typically large containers of liquid storage (1,000 liters or more), which can be made of plastic, fibreglass, concrete or steel. Header tanks normally sit in the ceiling outside of chicken sheds, on a water tower, or inside. By gravity, water is pumped into the potable system.
Pouring Vaccine Directly on the Drinkers
Most poultry operations can involve resorting to manually pour the vaccine’s water into the drinkers in the shed. Only this might be the choice in farms that do not have a dosing pump, a drug tank, or a header tank that would be useful and suitable for administering drinking water vaccine. The manual method is as complicated and labor consuming as the delivery of vaccine water into chick fonts, but with one aggravating factor: much greater are the amounts of water required.
