Response of Digestive Tract Size In Indonesian Native Chickens Fed Indigofera sp.

Abstract

The development of Balitbangtan native chicken through tractic feed is continually being advocated by the Indonesian government to enhance poultry protein consumption. Indigofera sp. is known for its flavonoid, tannin, and saponin content, which act as antimicrobial and anti-inflammatory agents for chicken digestive tract. The study aimed to investigate the response of Balitbangtan chicken’s digestive tract size substituted with Indigofera sp. A total of 40 chickens were used in four treatments with five replications. The four treatments were T0 (25% concentrate + 35% rice bran + 40% maize); T1 (T0 with substitution of concentrate with 10% Indigofera sp. meal); T2 (T1 + 2cc/l Bio-B); and T3 (22% concentrate + 31.5% rice bran + 10% Indigofera sp. meal + 36.5% maize). The collection of digestive tracts was measured by unit/100g. Data were analyzed using ANOVA by SPSS 26. Overall, the treatments did not differ significouldtly in digestive tract size (p>0.05). Treatment T1 showed great size of crop, proventriculus, duodenum, jejunum, cecum, colon, and pancreas sizes compared to T0, T2, and T3. In conclusion, the substitution of 10% Indigofera sp. meal in T1 resulted the best response in Balitbangtan chicken’s digestive tract size.
