Efficacy test of a hydrolysable tannin extract against necrotic enteritis in challenged broiler chickens
<p>A hydrolysable tannin extracted from chestnut (SaviotaN<sup>®</sup>) was tested for efficacy in controlling the proliferation of <em>Clostridium perfringens</em> in the gut of broiler chickens challenged via oral gavage first with coccidia (<em>Eimeria tenella,...

| description | <p>A hydrolysable tannin extracted from chestnut (SaviotaN<sup>®</sup>) was tested for efficacy in controlling the proliferation of <em>Clostridium perfringens</em> in the gut of broiler chickens challenged via oral gavage first with coccidia (<em>Eimeria tenella, Eimeria acervulina, Eimeria maxima)</em> at the age of 10 days, and then with <em>Clostridium perfringens</em> at the age of 15 days. We randomly allocated 150 broiler chickens within 5 poultry isolators (30 birds each). Dietary treatments consisted of a basal diet (C) composed of corn [575 g/kg on dry matter (DM)] and soybean meal (100 g/kg DM), barley bran (220 g/kg DM), corn gluten feed (30 g/kg DM), soybean oil (25 g/kg DM), vitamin mineral premix (49.5 g/kg DM), and four other diets obtained by adding chestnut tannin extract (1.5, 3, 5, and 12 g/kg during week 1, 10.0 g/kg during week 2, and 8.0 g/kg during the last two weeks, respectively) to C. At the age of 20 days, 15 birds/group were euthanised and individually examined for the level of gut infection by counting <em>Clostridium perfringens</em> and macroscopic gut lesions. Results demonstrated that chestnut tannin gave significant results even at low concentration levels in the feed (1.5 to 3.0 g/kg), but was actually efficient in controlling necrotic enteritis at levels ≥5.0 g/kg. The treatment (12.0 g/kg during the first week and 8.0 g/kg during the last two weeks of age) resulted very efficient in controlling the proliferation of <em>Clostridium perfringens</em> and in reducing the severity of gut damage compared to the untreated infected group.</p><p> </p> |
