Abstract

The purpose of the study was to find out the effect of adding rubber leaf (Hevea brasiliensis) flour containing tannin compounds in standard rations on the production performance of native chickens. The materials used were 64 native chickens (32 males and 32 females) aged 8 weeks, rubber leaf flour and non-AGP commercial ration with 21% protein content. The experiment was designed using Randomized Group Design with 4 treatments and 8 repetitions. Grouping was based on sex, and each repetition unit consists of 2 chickens. The treatment given was the addition of rubber leaf flour by 0% (P0), 3% (P1), 6% (P2) and 9% (P3) in 100% of commercial ration given to native chickens raising in individual battery cages for 6 weeks of trial period. The observed variables were consumption of dry matter (DM), weight gain (WG) and feed conversion ratio (FCR). Data were analyzed by Analysis of variance using General Linear Model procedures. The results of statistical analysis showed that the feeding trials affected non-significantly (P >0.05) on all variables observed. DM consumption, Weight Gain and FCR of P0, P1, P2 and P3 treatment group were respectively:  3279, 3260, 3274 and 3355g/head/week; 106.22, 105.15, 99.95 and114.43 g/head/week; 4.88, 5.02; 5.32 and 4.66. Based on the results, it can be concluded that rubber leaf flour can be used up to a level of 9% as alternative to synthetic antibiotic growth promoter (AGP), and produce the same production performance as native chicken production given non-AGP commercial rations.

Abstract

The purpose of the study was to determine the effects of adding rubber leaf flour (Hevea brasiliensis) to non-antibiotic growth promoter (non-AGP) commercial rations on dry matter, organic matter and nitrogen retention in native chickens. The materials used were 64 native chicken (32 male and 32 female) aged 8 weeks, non-AGP commercial ration and rubber leaf flour. The experimental design used was a Randomized Block Design (RBD) with 4 treatments and 8 replications. Grouping based on sex, and each replication unit consisted of 2 chickens. The treatment given was the addition of rubber leaf flour by 0% (P0), 3% (P1), 6% (P2) and 9% (P3) in a 100% commercial ration. The observed variables were dry matter (DM), organic matter (OM) and nitrogen (N) retention. Data were analyzed using analysis of variance, and the results showed that the addition of rubber leaf flour in the rations had no significant effect (P>0.05) on the observed variables. Retention of Dry Matter, Organic Matter and Nitrogen in treatment groups of P0, P1, P2 and P3 were respectively: 75.40, 78.45, 77.54 and 77.64%; 77.92, 78.38, 78.84 and 77.48 %; and 53.67, 57.69, 54.53 and 56.45%. In conclusion, the use of rubber leaf flour up to the level of 9% can highly enhance the retention of DM, OM and Nin native chicken, and hence it will also open and facilitate its potency as herbal feed additive as alternative to synthetic- AGP.

Abstract

The research aimed to analyze the effects of adding rubber leaf (Hevea brasiliensis) flour in non-AGP commercial rations on the blood cholesterol levels of broiler chickens. The materials used were 200 heads of Day Old Chick (DOC) unsex from MB-202 strain, non-AGP commercial ration containing 22% protein, and rubber leaf flour with a tannin content of 2.5% DM basis. The experiment was designed using a completely randomized design (CRD) with four treatments and five repetitions, and each repetition unit consists of 10 DOCs. The treatment was the addition of rubber leaf flour by 0% (P0), 5% (P1), 7,5% (P2), and 10% (P3) in 100% of the commercial ration given. Broiler chickens were raised in colony battery cages for five weeks of the trial period. The observed variables were cholesterol, triglyceride, HDL, and LDL plasma levels. Data were analyzed using analysis of variance and Duncan's multiple range test. The results showed that the estimated tannin compounds in rubber leaf powder consumed were 0.11%-0.22% and that the feeding treatment significantly decreased (P<0.05) blood cholesterol and triglyceride levels and significantly increased (P<0.05) blood HDL levels. Still, it had no significant effect on the LDL levels of broiler chickens. Based on the study's results, it can be concluded that adding 7.5%-10% rubber leaf flour to commercial rations can be used as a feed additive for reducing blood cholesterol levels in broiler chickens.
