Abstract

The use of plant bioactives to replace antibiotics are now widely investigated. Turmeric or Curcuma longa (CL) and curcuma xanthorrhiza (CX), are commonly used by human and known to have active ingredients as antimicrobial. Therefore a research was conducted to evaluate the possibility of using these plant bioactives to replace antibiotic in poultry feed. The bioactives concentration of the CL and CX powder were measured prior to the feeding trial and then supplemented into standard diets of broiler chikens. The levels tested in this trial were based on the active ingredients that could inhibit growth of bacteria and fungi, i.e., low, medium and high levels of the CL and CX, respectively. The combination of low level of CL + high level of CX and low level CL +  medium level of CX were also tested. A diet without feed additives and with antibiotics were used as controls. Each diet was fed from day old to 35 days old, replicated 6 times and each replication consist of 15 birds. Results showed that neither the antibiotic tested nor the turmeric (CL), xanthorrhiza (CX) nor the mixture of CL and CX gave significant (P>0.05) improvement on performances (body weight, FCR and mortatlity), nutrient digestibility of feed and carcass yield of broilers.

Abstract

Besides chewy, red in color, duck meat also have a distorted smell (fishy/off-odor). For consumers who are not familiar, the smell is not preferred. Duck meat contains high unsaturated fatty acids. Unsaturated fatty acid is an ingredient which is prone to oxidation. Two strains: Alabio and Cihateup ducks were used in this study, each consist of 3 replications. Four treatments were: 1. Commercial diet without antioxidant (control = K0); 2. Beluntas leaf meal (0.5%) + commercial diet (KB) 3. Beluntas leaf meal (0.5%) + commercial diet + Vitamin C 250 mg / kg (KBC), 4. Beluntas leaf meal (0.5%) + commercial diet + vitamin E 400 IU/kg (KBE). This experiment was designed in Completely Randomized Design. The result showed that response of Alabio and Cihateup duck to feed treatment in saturated fatty acid content and unsaturated fatty acids in meat and skin of the same, namely the feed treatment of KBE high and low of KBC. Beluntas leaf meal as much as 0.5% + vitamin E in the feed could be reduced the intensity of off-odor and maintain good performance of duck.

Abstract

Most poultry feed in Indonesia are imported while some of local feed such as rice bran is available throughout the year. Rice bran contains fiber and phytic acid so it needs to be supplemented with degrading enzymes and phytase to be used as poultry feed. This experiment was aimed to evaluate the effect of various levels of degrading enzymes and phytase on performances of broiler chickens fed diet containing rice bran. Based on Completely randomized design, a number of 280 of day old chicks (unsexed) were allotted to receive 7 experimental diets: (i). P1 = basal diet (control); (ii). P2 = P1 + natugrain: xylanase 1650 EXU + β-glucanase 1200 BGU/kg; (iii). P3 = P1 + phytase 500 FTU/kg; (iv). P4 = P1 + phytase 1000 FTU/kg; (v). P5 = P1 + fibre degrading enzymes (PU42 + BS4) 7,5 unit /kg; (vi). P6 =  P1 + fibre degrading enzymes (PU4-2 + BS4) 7.5 unit /kg + phytase 500 FTU/kg; (vii). P7 = P1 + fibre degrading enzymes (PU4-2 + BS4) 7.5 unit/kg  + phytase 1000 FTU/kg. The chickens were fed and given water ad lib for 6 weeks and then some were slaughtered for carcass evaluation. Results showed that supplementation of 1000 FTU/kg phytase to the diet improved feed efficiency and percentage of breast weight of chickens significantly (P<0.05). Supplementation of other levels of phytase, fiber degrading enzymes and its combination levels into the diets did not affect feed consumption and live weight gain of the chickens.

Abstract

Solid heavy phase (SHP), a by product material of palm oil factory obtained by ceramic filtration from liquid waste could be used as a feedstuff to replace corn in poultry diet. A series of experiment was carried out to improve nutrient value of the SHP by supplementation of enzymes and amino acids in order to increase the proportion of SHP to substitute corn in layer diet. There are three enzymes i.e.: Balitnak production (BS4), a commercial single enzyme (consist of mannanase) and comercial multienzymes were tested. All the enzymes were mixed with fresh SHP in different dose, dried and ground. The nutrient digestibility of these materials was measured in order to decide the optimum level of each enzyme. Based on this result, a feeding trial was carried out. Experimental diets were formulated to study the effect of substitusion of 25% or 50% corn with dried SHP or enzymes-treated SHP on the performances of the layers. The effect of methionine and lysine supplementation into diets contained high levels of SHP was also studied. Results showed that all enzymes studied could increase the energy (TME) of the SHP. BS4 enzyme and the commercial multienzimes, except single enzyme, also increase the true protein digestibility of the SHP. The optimum dose of each enzyme for each kg dry mater of SHP was 13.3 ml BS4, 2 g single enzyme and 3 g multienzymes. Substitution of 25% corn in layer diet with dried SHP or enzymes-treated SHP did not significantly impair the performances (hen-day egg production and FCR) of layers. However, substitution of 50% corn with SHP + multienzymes or SHP + single enzyme significantly impaired the performances of the layers. Addition of methionine and lysine amino acids restored the performance of the hens fed with SHP + commercial multienzyimes, but not those fed with high levels of SHP + commercial single enzyme. Substitution of 50% corn with SHP + BS4 enzime did not significantly impaire the performance of layers and therefore, addition of amino acids into the diet was not required. Substitution of 25% or 50% corn with dried SHP or enzymes-treated SHP did not affect the egg quality (HU, yolk color index and shell thickness). It is concluded that solid heavy phase (SHP) could be used to substitute 25 to 50% corn in layer diet, especially when the SHP was treated with BS4 enzyme.
