Abstract

This research had been conducted to obtain a feed formula that is capable of supporting optimal production performance  both in broilers and laying hens fed on feed containing fermented jatropha seed meal and addition saccarides. Fifty four broiler and fifty four layer were used.  Nested classification was the experimental design with bird kinds as group, levels of fermented Jatropha curcas meal (JCM-F) (9%, 12%, 15%) as  sub group and  levels of fructooligosaccharida/FOS (0.5%; 1%; 1.5%) as a sub sub group.  There were 3  replications in each treatment. Jatropha curcas meal was fermented with lactid acid bacteria (L. acidophilus and Bifidobacter spp) for 12 x 24 hour in 37oC.  The objective of the research was to evaluate growth, feed consumption, nutrient digestibility (crude protein and gross energy), blood metabolites  (glucose, cholesterol and trgliseride).  The results showed that the type of chicken had significant effect on growth and protein retention. The level of Jatropha curcas meal had significant effect on blood  serum triglyseride concentration.  On the other hand, the level of FOS had no significant effect on all variables. It could be concluded that Jatropha curcas meal  is better as broiler feed than layer feed with 0.5% FOS. However, to be used as feed of laying hens, it requires further optimalization of the fermentation process. Animal Production 15(2):98-105, May 2013

Abstract

The experiment was conducted to determine the nutrient digestibility and egg yolk pigment intensity of local ducks which fed shrimps head meal, leucaena leaf meal and L-Carnitine supplement.  The experimental method used was a Completely Randomized Design (CRD) with four treatments i.e : R0 (feed with  leucaena leaf meal), R1 (feed with 25 ppm L-Carnitine supplement), R2 (feed with 2% shrimps head meal) and R3 (feed with 4% shrimps head meal). A total of  0,20% FeSO4/kg feed were supplemented to all treatments.  The results showed that L-Carnitine supplements and fed shrimps head meal  (2% and 4%) have no significant effects (P>0,05) on crude fat and crude protein  digestibility  but have significant (P<0.05) effects on yolk pigment intensity.  L-Carnitine supplements resulted in 86,69% crude fat and 90,78% crude protein digestibility).  Ducks fed with 4% shrimps head meal (R3) produced eggs with highest yolk pigment intensity (10,55).

Abstract

The purpose of this study was to know the effect of utilization of various kinds of binders in the making of complete diet that was made of several species of forages that was viewed from its physical properties (hardness and durability).  There were two formulations of complete feed and four kinds of binders a pelleting machine was used in this study.  Factorially, based on Completely Randomized Design (CRD) was used with feed formulation (A) with two levels namely elephant grass and the leaves of leucaena (a1) and rice straw and peanut straw (a2) as the sources of forage as the first factor, and the kinds of binders (B) with 3 % levels of each binders.  Four levels of binders namely b0 (without binder), b1 (lignosulphonate), b2 (bentonite) and b3 (CMC) were as the second factor.  There were 3 replications in each treatment combination.  Based on the results of this study, it was conclude that the hardness of pellets of complete feed was affected by feed formulations based on different kinds of forage and pellets binders, but not for durability of the pellets.  The highest value of hardness was achieved by a1b1 formulation.
