  Background and Objective: The utilization of by-products of palm oil industry consists of palm kernel cake (PKC), palm oil sludge (POS) as feed is limited duo to their high lignin content. Probiotics are able to create a balance of microbes in the digestive tract thus creating optimum conditions for digestion of fibrous feed and improving feed conversion efficiency, which in turn can increase the production of livestock. The objective of this research was to determine the level of replacement concentrate ration of Etawa Crossbred dairy goat (ECDG) with concentrates formulated by various of by product of palm oil industry (palm kernel cake (PKC) and palm oil sludge (POS)) that have supplemented with probiotics. Materials and Methods: Research was conducted using completely randomized design (CRD) with 5 treatments concentrate ration replacement and 4 replications (Treatment A: about 100% concentrate standard (CS) and 0% concentrate of by products of palm oil industry (CBPO), B: 75% CS+25% CBPO, C: 50% CS+50% CBPO, D: 25% CS+75% CBPO and Treatment E). 0% CS+100% CBPO. Parameters measured were quality of milk, ie protein, fat, solid non fat (SNF), density and mineral (Ca and P). Results: The results showed that protein, fat, SNF, density and mineral (Ca and P) was not significant (p>0.05). Conclusion: From the overall parameters it can be concluded that the use of a byproduct of palm oil industry until 100% for ECDG ration does not affect the quality of milk in terms of protein, fat, minerals and density of milk.

  Objective: The objective of this study was to evaluate the effects of calcium (Ca), phosphorus (P) and manganese (Mn) supplementation during Oil Palm Frond (OPF) fermentation by Phanerochaete chrysosporium on laccase activity and in vitro fiber digestibility. Materials and Methods: This study was carried out using a randomized block design with 3 treatments (Addition of Ca, P and Mn) and 5 replications. The following treatments were performed: T1 = Ca 2000+P 1000+Mn 150 ppm, T2 = Ca 2000+P 1500+Mn 150 ppm, T3 = Ca 2000+P 2000+Mn 150 ppm. The data were subjected to an analysis of variance (ANOVA) and differences between treatment means were tested using Duncan’s Multiple Range Test (DMRT). The parameters measured were as follows: Laccase activity (U mL –1), Neutral Detergent Fiber (NDF) digestibility (%), Acid Detergent Fiber (ADF) digestibility (%), cellulose digestibility (%) and hemicellulose digestibility (%). Results: Results revealed that laccase enzyme activity, NDF digestibility, ADF digestibility and cellulose digestibility were significantly increased by the addition of P in T3. However, T2 and T3 non-significantly affected (p>0.05) the digestibility of hemicelluloses. Conclusion: It is concluded that supplementation of OPFs with Ca 2000, P 2000 and Mn 150 ppm resulted in the highest laccase activity and in vitro fiber digestibility.

  Objective: The aim of this research was to identify the rumen microbial populations and determine the in vitro nutrient digestibility of fermented oil palm fronds (FOPF) by Phanerochaete chrysosporium, which were supplemented with Ca, P and Mn minerals and combined with tithonia (Tithonia diversifolia) and elephant grass (Pennisetum purpureum). Methodology: This study used a randomized block design consisting of 4 treatment groups: T1 = 20% FOPF+80% (tithonia+elephant grass), T2 = 40% FOPF+60% (tithonia+elephant grass), T3 = 60% FOPF+40% (tithonia+elephant grass) and T4 = 80% FOPF+20% (tithonia+elephant grass). Four replicates were used per treatment. The ratio of tithonia to elephant grass was 1:4. Data were analyzed by analysis of variance (ANOVA) and differences among means were tested using Duncan’s multiple range tests (DMRT) with 5 and 1% confidence intervals. The measured variables were total bacteria, total protozoa, dry matter digestibility (DMD), organic matter digestibility (OMD) and crude fiber digestibility (CFD). Results: The results showed that total population of bacteria, DMD, OMD and CFD were the highest (p<0.01) in the T1 treatment. Total protozoa were lowest in T1 but the difference with the other treatments was not significant (p>0.05). Conclusion: T1 (combination of 20% FOPF and 80% tithonia+elephant grass) had the best effect on rumen microbial populations and in vitro digestibility.

  Objective: The objective of this research was to determine the productivity of sheep that were fed a complete diet consisting of ammoniated cocoa waste (leaves and pod husks) supplemented with minerals (phosphorus and sulfur) and Saccharomyces cerevisiae (S. cerevisiae). Methodology: Four local sheep aged 10 months to 1 year were used in this study and were divided into 4 feed treatment groups (four sheeps per/treatment) with four replications for each treatment as follows: Treatment A served as the control and sheep were fed a complete diet that consisted of cocoa waste (fiber source)+concentrate, treatment B consisted of treatment A+0.4% phosphorous (P) and 0.3% sulfur (S), treatment C consisted of treatment B+1% S. cerevisiae and treatment D consisted of treatment B+2% S. cerevisiae. Each treatment had a fiber source: concentrate ratio of 40:60. The data collected included feed intake, nutrient digestibility, average daily weight gain and feed efficiency. Results: Treatment C had highly significant effects (p<0.01) on dry matter intake, organic matter intake, crude protein intake, digestibility, crude fiber intake, average daily gain and feed efficiency. Thus, the complete diet consisting of ammoniated cocoa waste increased feed intake, digestibility, daily weight gain and feed efficiency. The use of ammoniated cocoa waste-based complete feed with minerals (P and S) and 1% S. cerevisiae yielded 130 g/day of average daily weight gain. Conclusion: The diet consisting of ammoniated cocoa waste supplemented with minerals (P and S) and 1% Saccharomyces cerevisiae can be effectively used for fattening sheep.

  Objective: The aim of this research was to determine the influence of palm oil industry by-products (palm kernel cake and palm oil sludge) and Paitan (Tithonia diversifolia, TD) as roughage on the production and quality of Etawa crossbreed (EC) goat milk. Materials and Methods: Eighteen EC dairy goats on their second lactation month were used in this study. This study utilized a Completely Randomized Design (CRD) that consisted of 6 treatments and 3 replicates. The treatments were as follows: (A) 50% roughage+50% soybean meal waste (SMW)+0% palm oil concentrate (POC), (B) 50% TD+50% SMW+0% POC, (C) 50% TD+37.5% SMW+12.5% POC, (D) 50% TD+25% SMW+25% POC, (E) 50% TD+12.5% SMW+37.5% POC and (F) 50% TD+0% SMW+50% POC. The variables observed in this study were the production and quality of Etawa crossbreed milk (protein and lactose). Results: Results showed a milk production rate (1.44-1.85 kg/head/day) with a milk protein concentration (3.48-3.76%) and a lactose concentration (4.01- 4.16%). Using palm oil industry by-products and TD as an early feed can significantly increase milk production (p<0.01), but there was no effect on milk quality (p<0.05). Conclusion: The TD and palm oil industry by-products can be used as an alternative feed for animals. The optimal feed for dairy goats was 50% TD+25% SMW+25% POS (treatment D).

  Background and Objective: Liquid biourine organic fertilizer can affect the physical, chemical and biological fertility of soil. Mycorrhizal biofertilizers can help plants to supply and absorb nutrients, especially phosphorus, which is low in availability in acidic/critical soils. The aim of this study was to characterize, test and prove that the administration of biourine liquid organic fertilizer and Arbuscular mycorrhizal Fungi biofertilizer (AMF) as a biotechnology agent, was able to improve the productivity of ex-coal mine lands and also affect the content of forage fiber feed fractions. Materials and Methods: An experiment using a completely randomized design with 4 types of treatment and 5 repetitions was conducted. The treatments consisted of: (1) Biourine concentration of 0%+AMF 20 g pot–1, (2) Biourine concentration of 15%+AMF 20 g pot–1, (3) Biourine concentration of 30%+AMF 20 g pot–1 and (4) Biourine concentration of 45%+AMF 20 g pot–1. Variables observed were Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF), hemicellulose, cellulose and lignin. Results: The results of various analyses showed that the treatment had a highly significant effect (p<0.01) on all variables observed. The treatment with 45% biourine+AMF 20 g pot–1 resulted in lower ADF, NDF and lignin contents and produced higher cellulose and hemicellulose content than the treatments with 30% biourine+AMF 20 g pot–1, 15% biourine+AMF 20 g pot–1 and 0% biourine+AMF 20 g pot–1. Conclusion: Biourine liquid organic fertilizer and Arbuscular mycorrhizal Fungi biofertilizer (AMF) are biotechnology agents that improve the productivity of ex-coal mine land and also affect the content of forage fiber feed fractions.

  Background and Objective: The exploration of new and quality animal feed sources is very important for identifying supplements to the limited supply of grass. Palm oil processing industry byproducts, tithonia plants and corn waste have very good nutrient content for animal feed. The research objective was to study the potential of palm oil processing industry byproducts, tithonia (Tithonia diversifolia) and corn waste by in vitro digestion as feed ingredients for Etawa crossbred dairy goats (ECDGs). The long-term goal of this study was to obtain a concentrate ration formula by utilizing industrial byproducts of the palm oil industry, local forage of tithonia and corn waste, for ECDG with the ultimate goal of increasing the productivity of ECDGs to meet milk self-sufficiency by 2020. The theme of this study is in line with Andalas University’s Master Plan Research with a focus on Food Security. Materials and Methods: This study used a randomized complete design consisting of three treatment groups; (A) Concentrate Ration (CR)+Tithonia, (B) CR+Tithonia+corn waste and © CR+corn waste. Five replicates were used per treatment. The CR consisted of 30% palm kernel cake (PKC), 20% rice bran, 9% corn, 40% tofu waste and 1% mineral. The protein and crude fiber content of the CR was 13.78 and 13.32%, respectively. The data were analyzed using one-way analysis of variance (ANOVA) and differences between treatments were tested using the Duncan multiple range test (DMRT) with 5% confidence intervals. The variables measured were dry matter digestibility (DMD), organic matter digestibility (OMD), crude protein digestibility (CPD) and digestibility of fiber fractions (NDF, ADF and cellulose). Results: The results showed that DMD, OMD and digestibility of fiber fractions (NDF, ADF and cellulose) were greatest (p<0.05) in treatment B. However, treatments A, B and C did not affect the CPD and the results were significant. Conclusion: It was concluded that the combination of concentrate ration with tithonia and corn waste resulted in the highest in vitro digestibility.
