enrize 80 - the best agp for control of clostridium perfringens
DESCRIPTION
Clinical Necrotic Enteritis is a severe enteric disease in broilers caused by the toxins of Clostridium perfringens. The condition is marked by high mortality and severe fibrino-necrotic enteritis. An associated hepatitis (necrotic hepatitis and/or cholangiohepatitis) is also commonly seen. • Clostridium perfringens is an inhabitant of normal chicken intestines. Increased numbers, however, are associated with both clinical disease and subclinical disease; both resulting in performance losses. • Coccidiosis and certain feedstuffs are often considered to be important predisposing factors for Necrotic Enteritis, however, the disease can occur even in flocks with good coccidiosis control and corn-soy diets. • The broiler industry has a virtual zero tolerance (except in the case of “organic broilers) for clinical Necrotic Enteritis. When the disease appears, immediate steps are taken (water treatment, change in coccidiostat, change in feedstuffs, etc.) However, the incidence and losses due to subclinical Necrotic Enteritis are more difficult to quantify and are probably underestimated. • Economic losses from subclinical Necrotic Enteritis have been estimated to be up to $0.05 per broiler. There is evidence to suggest that subclinical Necrotic Enteritis can affect feed conversion, body weight, condemnations, and mortality. • Subclinical Necrotic Enteritis can be monitored through necropsy (gut scoring), monitoring condemnations, and measuring broiler performance parameters. • The use of effective in-feed antibiotics is the best method currently available for preventing losses due to subclinical Necrotic Enteritis in broilers.TRANSCRIPT
