Abstract

Ruminants need micro mineral for both their own requirements and rumen microbe activities. The objective of this research was to study the effect of Mn, Cu, and its combination addition in ration on the activity of in vitro fermentation using sheep rumen liquid. This research was conducted at Laboratory of Ruminant Nutrition Faculty of Animal Science Bogor Agricultural Institute. The rations were R0 = basal ration; R1 = basal ration + 40 ppm Mn; R2 = basal ration + 10 ppm Cu; dan R3 = basal ration + 40 ppm Mn + 10 ppm Cu. The result indicated that addition of Mn, Cu, or Mn+Cu did not significantly influence (P>0.05) pH, NH3, bacteria and VFA; but they significantly increased (P<0.01) dry matter digestibility (DMD) and organic matter digestibility (OMD). The average: pH was 4.78 ± 0.07 – 4.89 ± 0.06; NH3 was 6.77 ± 2.07 – 7.47±0,67 mM, and VFA was 93.19 ± 55.79 – 136.61±15.31 mM.  R1 gave the highest value of DMD (57.63%) and OMD (70.32%). The VFA related positively to NH3 (r = 0.86); with the equation Ý = -266.9 + 54.182 X and R2 = 0.74.  It was concluded that additional of Mn, Cu, or Mn+Cu did not alter pH, NH3, and VFA. The additional of Mn altered DMD, but additional of Mn+Cu reduced DMD and OMD. Key Words: pH, NH3, VFA, DMD, OMD

Abstract

Recently, fermentation of low quality feed such as agro industry by products has been widely applied to produce enriched animal feed and improve animal productivity. The purpose of this study was to evaluate in vitro digestibility of fermented complete feed by using agro-residues from sago starch processing industries as main source diet.  Feed was formulated on the basis of 40% sago residue and mixed with other ingredients (rice brand, coconut meal, bread by product, soybean meal and soybean hulls) to fulfill the requirement of sheep with 16,10% of CP, 2,80 Mkal ME/kg and TDN 60,88% based on calculation. Mineral and Urea were added in the complete feed to reach mineral and CP requirements of sheep.  Complete feed formulation was fermented by using 3 commercial fermentation products (Saus Burger Pakan® (SBP), Probion® and EM4®) for 21 days. Total and types of microbes from commercial fermentation products which were utilized in this study were not determined. Parameters measured in this study were pH, NH3, IVDMD (in vitro dry matter digestibility), IVOMD (in vitro organic matter digestibility) and VFA total. The model used for the statistical analysis was completely randomized design (CRD) with 4 treatments (control and 3 different commercial fermentation products) and 4 replications.  The results of this study indicated that administration of different commercial fermentation products into fermented complete feed based on sago residues significantly influenced (P<0.05) on pH, NH3, VFA total, IVDMD and IVOMD. Generally, commercial fermentation products mainly SBP produced better feed quality by improving the values of pH, NH3, VFA total, IVDMD and IVOMD. However, types and total microorganisms were needed to be determined before experiment.

Abstract

Animals are considered as source of protein should be improved their productivity with the minimum cost production. Agro-industrial by products have been used as animal feed to reduce feed cost. The purpose of this study is to evaluate agro-industrial by product in Aceh as potential local feed for ruminant animals based on chemical composition, fiber fraction and in vitro rumen fermentation. There were eight sources of agro-industrial by products (sago residues, coconut meal, soybean-ketchup by product, coffee pulp, cacao pod, sago tree, corncob, and rice brand) which were collected from 3 different locations in Aceh.  All agro-industrial by product samples were dried at 600C for 24 h and ground to pass a 1 mm sieve. Grounded samples were analyzed to determine chemical composition, fiber fractions and in vitro rumen fermentation. Incubation was conducted at temperature 390C for 48 h in water bath with three replicates. Data for in vitro rumen fermentation were statically calculated by using SPSS differences between treatments were stated (P≤0.05) by using Duncan Multiple Range Test (DMRT). The results indicated that agro industrial by product from coconut meal, ketchup residues, coffee by product, cacao by product, and rice brand can be used as source of protein and industrial by product from sago by product, sago tree and corncob can be used as source of energy. Neutral detergent  insoluble  CP (NDICP) and Acid detergent insoluble CP (ADICP)  were relatively high for sago by product, sago tree and rice brand but relatively low for cacao by product and corncob. The value of incubated pH for most feed samples was in the normal range. In vitro dry matter digestibility (IVDMD) and in vitro organic matter  digestibility (IVOMD) were significantly difference (P≤0.05) each agro-industrial by products with the highest for sago and the lowest for coffee by product. In conclusion, agro-industrial by products had a potential feed for ruminant animals both as protein and energy sources. However, feed ingredients with high fiber content and low degradability, further treatments such as physical, chemical and biological treatments were required to improve the feed quality.
