Poultry Health at Elanco

Coccidiosis is a ubiquitous parasitic disease affecting the intestinal tract of poultry caused by specific species of the protozoal parasite Eimeria.

Signs of coccidiosis in poultry include^1,2 :

The majority of poultry infected with coccidia show no symptoms, but young or immunocompromised animals may suffer more severe signs of disease. Keeping the challenge as low as possible is critical to protecting bird health and performance.

Managing coccidiosis is best achieved through a holistic approach. While it is important to use an appropriate anticoccidial in at risk birds, it is also critical to consider how the immune status of the flock and management factors may help reduce the impact of coccidiosis.

There are a number of infectious diseases which can affect poultry, impacting their health and performance. These diseases include:

The Elanco Food Safety Program works alongside the British Egg Industry Council (BEIC) to support producers in ensuring their eggs are free from salmonella.

Birds can develop infection directly or indirectly, depending on the species of the bird. Direct infection may be caused through the consumption of worm eggs from the floor or pasture or through contact with infected wild birds. Worm eggs can also be brought in to a system on food sacks, litter or clothing. This is irrespective of whether the birds are housed or free range. Indirect infection may be caused by consuming intermediate hosts (earthworms, insects, slugs) infected by parasitic worms.

Worm eggs require warm, damp conditions to develop and cannot be killed through disinfectants - they can survive for years in the environment. They build up in large numbers where there is concentrated use of land by birds (overstocking or little rotation of land), especially if poorly drained.

ß-Mannans (ß-galactomannans) are non-starch polysaccharide (NSP) fibres found in leguminous feed ingredients including soybean meal. The animals’ innate immune system recognizes ß-mannans as an intruder because they have a similar molecular pattern to some pathogens.^3,4,5,6,7 This triggers an innate immune response which consumes energy and nutrients.^8,9,10,11 Even small amounts of ß-mannans trigger the response. The presence of the ß-mannan fibres causes the diversion of energy away from growth.^8-11(It also reduces nutrient absorption ^14,15 and lowers secretion of insulin.^12,13) This response can consume about 3% of total metabolisable energy.¹⁶

A health enzyme can be used to combat this. It works by breaking down ß-mannans in soybean meal and other common feedstuffs.^14,16 By acting on the ß-mannans in the feed, the innate immune response is minimized. The resulting breakdown product created does not trigger the Feed-Induced Immune Response (FIIR). Instead, the animal’s body directs energy to growth and performance.^8-11

Elanco has many years of experience in delivering additional value to its customers through its comprehensive data analytics systems. These systems have allowed Elanco to build a wealth of experience and comparative historical data, which can be used to benchmark production systems.

Elanco’s Health Tracking System (HTSi™) is an established, independently verified and globally recognised broiler benchmarking platform that incorporates multiple lesions to assess gut health, locomotor function, respiratory stability and bird welfare¹⁷.

It has been used successfully for many years to monitor the performance of birds and help drive towards future improvements.
