Poultry Bio-Security Measures

This is the prevention of disease causing agents entering or leaving any place where they pose a risk to farm animals and humans, or safety of quality of food products. Good bio-security should be practiced at all times, not just during a disease outbreak. By taking preventative measures before knowing its spread in the country, you can ensure your flock grow to maturity in good health. Guidance on the use of Insecticide for the treatment of animal vehicles Before animals are loaded on a vehicle, the inside compartment must be treated with a virucidal insecticide spray approved by the HSE. Authorized pyrethoids for use against flying insects can be used in animal housing or similar areas as well such as abattoirs. The user must do due diligence to not exceed manufacturers instructions as this may only lead to surface water pollution. Guidance on siting poultry house The site for any poultry house should be carefully considered before deciding where your poultry house should be. For caged birds in modern commercial poultry, feed store houses and pens should not be cited next to any water bodies, neither should nearby water bodies be used as a source of water for cleaning out a house as there is a threat of fecal matter from wild birds which could potentially be a source of avian influenza or Newcastle Disease. Wildfowl are a major source of avian influenza introduction in a commercial unit. They rarely travel more than 1 km away from water bodies in search of food. Therefore, the further away pens are situated from water, the better. Local knowledge of the area...

Newcastle Disease – Causes, Signs & Symptoms, Treatment

Newcastle disease is a widly contagious disease in poultry and other wild birds including Turkey, geese, ducks, guinea fowl, quails, pigeons, ratites e.g Ostriches. In poultry, the disease is more common in hens and they can be affected at any age. ND are caused by Paraxymoviruses (Paramyoxiviridae family) and depending on their host, vaccines can give a short to long term immunity depending on prior vaccinations.   Signs & Symptoms Newcastle Disease is characterised by marked variations in morbidity and high death rate amongst the flock. Highly virulent strains lead to death of infected bird 90% of the time. Physical symptoms include Greenish watery Diarrhea Gasping for breadth like one suffering from an asthma attack. Intermediate virulent strains produce severe nervous and respiratory signs such as Depression, twisting of head and neck, circling, paralysis, swelling of tissue around the neck. Some birds will spin around in gyratory movements, jump off the ground to heights of six to ten feet before crashing to the ground. Rough or thin shelled eggs or significant drop in egg production When disected, there are harmorhagic lesions on the alimentary canal from the beak leading to the vent, Haemorhages gathered between the gizzard and oesophagus. Oedematous Mucus coat Any potentially infected bird showing symptoms must be isolated immediately and should be confirmed in a laboratory before administering drugs. Causes of Newcastle Disease Once a bird has been infected, the virus can spread rapidly. It has been known to kill a whole flock in thousands due to exposure to infected birds. This is common in commercial laying birds kept in cages hence containment should be priority....
