Effect of Supplementation of Cassava Crude Extract in Drinking Water on Productive Performances of Broiler

Abstract

The use of herbs in economic animal husbandry is one way to reduce the use of antibiotics. Cassava leaves contain high amounts of tannins. With active ingredients to inhibit the growth of bacteria and disinfection that causes diarrhea Therefore, the purpose of this study was to determine the effects of supplementation of cassava crude extract in drinking water on broiler production performance. A total of 80 one -- day - old arbor - acre broiler mixes were randomly divided into 4 groups of 4 reps of 5 each, based on completely randomized design. The treatment consisted of (i) Drinking water mixed with antibiotic Oxytetracycline 0.3 mg/l. (ii), (iii) and (iv) Drink with tannin extract at levels 10, 20 and 30 mg/l, respectively. 42 day trial. The resultst showed that the broilers in the treatments at and 4 had adequate feed intake. 3,666.25, 3,671.25, 3,697.50 and 3,692.50 g/head (P>0.05) body weight gain 1,970.25, 1,985.50, 1,980.13 and 1,930.28 g/head (P < 0.05), growth rates 46.91, 47.27, 47.14 and 45.96 g/body/day (P < 0.05) , feed conversion ratio 1.86, 1.84, 1.86 and 1.91 (P < 0.05), The survival rates were 100, 95, 100 and 95 percent (P>0.05) and food cost per kilogram body weight gain 32.56, 32.36, 32.68 and 33.74 baht (P<0.01). It can be concluded that supplementation with cassava leaves crude extract in drinking water at the level of 10-20 mg/l had a positive effect on growth performance.
