Health Management
Hybrid Poultry Farm has introduced hatchery vaccination in all day-old broilers against Gumboro, Newcastle and Infectious Bronchitis diseases. With intensification of broiler production, total or partial condemnation of carcasses has risen owing to poor growth rates, cellulitis, water belly, downgrades and high mortality. Because of these losses, the broiler industry has constantly tried to improve facilities, optimise the stocking densities and even improve some management techniques. Furthermore, broiler producers continuously seek new ways of reducing the condemnation rates at the slaughter house.
Recent trials have demonstrated that concentrating the vaccination in the hatchery could greatly improve profitability for farmers. In fact, the reduction of vaccinations applied in farms can help reduce the rate of mortality during growing, avoiding huge financial losses for farmers.
The vaccination of the day-old chicks in the hatcheries effectively started in the 1970s, with the use of Marek’s vaccine. Now vaccines against Newcastle disease, IB, and Gumboro are available for day-old vaccination.
Hybrid Village Chicken has subsequently introduced Transmune vaccination against Gumboro and Vitabron against Newcastle and Infectious Bronchitis diseases in day-old chicks at the hatchery. These vaccines have widespread use in Europe, Brazil, China and emerging markets in Nigeria and the Middle East.
These are the main benefits in moving vaccination from the farm towards the hatchery:
- The vaccine is handled by a Hybrid Poultry Farm team that is well trained and
monitored. Centralisation of controls at the hatchery ensures that the vaccine is precisely administered, according to the guidelines of the manufacturer. - The vaccine cold chain storage guidelines are easy to control at hatchery level. At the farm, it is far easier for the chain to be broken.
- Vaccination cover is 100% on all chicks at the hatchery, compared with 70-80% success rates at the farm. It further reduces stress on the birds in the farm, ensuring early and improved disease resistance.
- Sophisticated – and consequently expensive – equipment is more affordable and relevant for a large structure like a hatchery than for a poultry farm. Also, equipment can be better monitored and maintained in the hatchery. Vaccine application becomes more effective. The farmer has more time left to look after the vaccinated birds instead of worrying about vaccination.
- Spray vaccination, which is the best method for administration of respiratory vaccines like ND or IB, is much easier to apply. It is consequently more effective when given in the hatchery than on a farm. For effective immunization, this vaccination requires a dust-free environment. The farmer will only undertake one single Newcastle disease vaccination in the Broiler farm at Day 14, instead of two vaccinations, as was previously the case. This will reduce: stress for the birds; the use of vitamins before and after vaccination; post-vaccination reactions; and the cost of treatment.
As a result of the above, vaccination at the hatchery leads to better growth rates and lower mortality in the event of disease outbreak.
Hybrid Poultry Adopts A Two-prong Approach In Dealing with Gumboro And Newcastle Diseases Of Poultry At Hatchery
Gumboro disease
This disease was first isolated in the village of Gumboro in USA in the early 1960s. However, within twenty years the virus had spread to the rest of the world.
This viral infection attacks immune system of young birds, destroying the B lymphocytes in their immature stages in the Bursa. The virus is hard to kill, and can survive in moist old litter for four months. The virus can mutate and change its form, avoiding the immune system of the bird. It is common in huge poultry complexes, where birds are raised in multi-age systems. Chickens are more susceptible at 3 – 6 weeks of age, when Bursa is at its maximum rate of development and filled with B cells.
The affected birds discharge whitish diarrhoea, and they huddle together. Massive mortality is observed in non-vaccinated flocks: the mortality pattern has a bell shape curve and disappears in seven days.
Newcastle disease
This is a disease of poultry caused by a Ribulavirus, causing both respiratory and enteric infection in chickens of all ages. The virus enters via any mucosal surface: multiplying in the epithelium and spreading via the bloodstream to other organs, where fast multiplication occurs. This leads to a rise in virus concentration in the blood. It multiplies in all organs, especially the respiratory and intestinal tract, and in the case of virulent strains, in the nervous system.
Virus shedding occurs by faeces, as well as in the air through aerosols and dust. The most obvious clinical signs are sudden and massive mortality, with neurological signs like star gazing, limb paralysis and twisted necks. This leads to an inability to feed, resulting in greenish diarrhoea. For birds in production, there is a significant drop in egg production.
