Abstract

A research to improve ramie leaf utilization in local sheep ration by supplementation of deficient nutrients was conducted. Four rations as treatments were tested using 12 local sheep (16.5 ± 1.6 kg LW) in a block randomized design. The treatments were T1 = 3% BW of DM native grass; T2 = T1 + 0.75% BW (25% of DM native grass) of DM ramie leaf; T3 = T2 + supplements Cu, P and methionine; T4 = T1 + 1.5% BW (50% of DM native grass) of DM ramie leaf + supplements Cu, P and methionine. Ration consumptions and digestibility, plasma level of Ca and P and body weight changed were determined. Dry matter intake increased in line with level of ramie leaf offered and there were no significantly difference on digestibility between the rations. Native grass alone failed to give a positive body weight change of local sheep. Addition of 25% DM ramie to native grass (T2) increased intake of digested nutrient and reduced body weight loss. Addition of supplement (T3) at the same level of ramie leaf increased intake of digested nutrient and changed the curve slope to the positive direction after the third week of observation. Addition of 50% DM ramie leaf to native grass basal ration followed by supplementation (T4) improved intake of digested nutrient closed to recommended nutrient requirement and showed a positive body weight changed.

Abstract

Quality improvement of ramie leaves silage by the addition of water soluble carbohydrates (WSC) sources as many as 20% W/W fresh substance (FS) prior to 42 days of ensiling time was conducted in two experiments. First experiment examined three carbohydrate sources (cassava meal, pollard and coarse grinding corn) for their capacities to improve physical (color, odor, texture and spoilage), fermentative (pH, protein degradation, organic acid profiles), and utilities characteristics of the silages for ruminants (rumen fermentabilities and digestibilities) in vitro. The silages had bright greenish brown of color, lactic acid odor, and firm textures, categorized as highly fermentable and digestible feeds (dry matter digestibility >72%). Compare to other additives, cassava meal produced better silage. However, high butyric acid and protein degradation proportions in the silage were not seem in line to these data. Coarse grinding corn failed to do its function therefore produced poor silage quality. Second experiment was designed to confirm the previous results. Five carbohydrate sources (cassava meal, pollard, fine grinding corn, rice bran, and cassava extract meal) of the same functions were examined. The results confirmed that cassava meal produced very good ramie leave silages (Fleigh number >80) while the others produced quite good ramie leaves silage qualities (Fleigh number 40-60). All additives used in the second experiment successed to serve their functions in improving ramie leave silage qualities.

Abstract

The research was conducted to study the effect of addition of 7% DM maize hydroponic fodder (MHF) in corn silage on digestibility and milk production of dairy cows. The experiment used a completely randomized block design with two treatments, and four replications. The treatments were dairy cows fed with grass (Pennisetum purpureum), corn silage, and concentrate (R0), and dairy cows fed with grass (P. purpureum), corn silage, concentrate, and MHF (R1). This research used eight dairy cows with initial average milk production of 13.01±2.96 L/d. MHF was produced in a hydroponic system using bioslurry as a fertilizer enriched with mineral fertilizer. Variables observed were chemical composition of bioslurry, nutrient content of ration, daily dry matter intake, nutrient digestibility, Total Digestible Nutrient (TDN), and Digestible Energy (DE). Data were analyzed with ANOVA, except for milk production using ANCOVA. Supplementation of MHF resulted a higher total dry matter intake on R1 than R0 (P<0.05), 12.99±0.063 kg/head/d, and 11.98±0.295 kg/head/d, respectively. The digestibility of nutrients were not affected by the addition of MHF. Energy consumption in R1 was also higher than R0 (P<0.05), 49.95±0.36 Mkal/kg, and 46.11±0.54 Mkal/kg, respectively. Supplementation of MHF also increased nitrogen consumption, R1 was higher than R0 (P<0.05), 318.3±2.3 g/head/d, and 295.9±3.5 g/head/d, respectively, and could maintain the persistency of milk production at the end of lactation. It can be concluded that supplementation of MHF in corn silage can increase dry matter intake, energy consumption, and nitrogen consumption, also can maintain nutrient digestibility and maintain persistency of milk production during late lactation of dairy cows.Key words: bioslurry, dairy cow, greenhouse fodder, nutrient digestibility

Abstract

This study aimed to compare local dairy farmer ration formula with national research council in producing higher feed efficiency and milk production. This study had two stages. The first stage was in vitro study of dairy farmer rations which have different raw materials (R3, R4, and R5) with NRC based ration (R2) and Demo Farm ration (R1). The variables measured in this stage were proximate composition, volatile fatty acid, ammonia, dry matter and organic matter digestibility. The first stage used a randomized block design with five treatments, three groups of ruminal fluid, and three replications. The second stage used nine lactating cows with three periods of lactation (one, three, and other) and used a randomized block design with three treatments, three groups, and one replication. Parameters measured were dry matter intake, manure score, milk production, body weight gain, body condition score, and technical and economical efficiencies. The first stage result showed that R1, R2, and R3 were three best rations in nutrient composition and fermentability (ammonia and volatile fatty acid concentrations were optimum for microbial growth and high digestibility), so in conclusion those three rations were the best rations and should be compared by in vivo method. The result of the second stage showed that all tested rations were not significantly different in milk production, performance and efficiency, so in conclusion those three rations have the same quality.Key words: dairy cattle, milk production, profitability, rations test

Abstract

Green house fodder (GHF) is high quality forage that is produced by hydroponic vertical farming system in green house in short time. Silage is also high quality feed that is available all year rounds. The research aimed to evaluate productivity and nutritive value of mungbean’s GHF and its supplementation effect with and without silages based ration on dairy cow performances. The research was divided into two experiments. The first experiment studied the seed density (A1= 1.5 kg/m2; A2= 2.5 kg/m2; A3= 3.5 kg/m2) in bioslurry:ABmix 25:75 media as nutrient solution and used randomized block design. The second experiment studied mungbean’s GHF supplementation that used twelve lactating dairy cows with 2 x 2 randomized factorial block design 2 x 2. Factor 1 compared silages utilization (S0= without silages; S1= silages) and factor 2 tested mungbean’s GHF supplementation level (G0= 0% DM; G1= 5% DM). The results showed that A1 produced the highest biomass conversion (5.27). GHF had high digestibility and fermentability indicated that GHF had potential as dairy feed. Supplementation of GHF increased nutrient intake. Silage is a high quality feed, so that GHF supplementation did not give significant effects on nutrient digestibility and milk production. It can be concluded that the low seed density (1.5 kg/m2) had high productivity and nutrition quality, and its supplementation increased nutrient intake, but did not affect nutrient digestibility and milk production.Key words: green house fodder, mungbean, bioslurry, dairy cow, silages

Abstract

This research aims to measure supply chain performance of dairy concentrate in cooperative with the SCOR-AHP approach and develop improvement based on the performance result, and to analyze the quality suitability as a basis to develop a comprehensive quality standard and its quality control mechanism. This research was conducted at a dairy farmer cooperative located in West Java. The analysis used to measure the performance was supply chain operation reference-analysis hierarchy process (SCOR-AHP). For measuring the product quality, ten post-production concentrate samples, 27 samples after the distribution process, and 25 samples for homogeneity test from five mixer machines were taken. Concentrate quality parameters were moisture, ash, crude fat, crude protein, crude fiber, total digestible nutrients (TDN), and salt content. Post-production samples data were compared with Indonesian National Standard (SNI) using one-tailed one-sample t-test, samples data from the field were tested using two samples independent t-tests compared to post-production samples data, and homogeneity test was seen from the coefficient of variation value of the salt content. The results show that the supply chain performance value of dairy cow concentrate at the cooperative is excellent. The nutrient content complies with SNI, but the homogeneity of the mixture is classified as poor category. The nutrient content of samples taken from the field shows differences with post-production samples except for TDN. The excessive total cost can be utilized to enhance performance in generating a better quality product. The cooperative should enhance homogeneity by concerning the mixing process and maintain the quality consistency by reformulating, stabilizing the quality of feedstuff, and calculating stock properly to avoid longer storage.

Abstract

Kunak is the biggest community for a traditional dairy cattle farmer in West of Java. Providing good qualities and quantities of forage continuously in a year for ruminants, still be one problem in this community caused by different forage production between the dry season and rainy season. High forage production in the rainy season could be stored as silage to provide forage requirement in the dry season. These research examined in 2 experiments. The first experiment aimed to determine the effect partial-substitute of fresh forage uses grass silage on the quantities and qualities of daily milk production. The second experiment aimed to determine the quantities and qualities of dairy cattle milk production, affected by adding Gracilaria sp (GS) on partial-substitute of fresh forage uses grass silage and palm kernel-meal (S-PKM) on daily feed. These research uses complete randomized design divided into two treatments (to substitute as much as 0% and 10.08% Dry matter of fresh forage with grass silage) with five replications on the first experiment and three treatments (0%S-PKM-0%GS; 19.51%S-PKM-0%GS; 15.03%S-PKM-2.03%GS) with three replications on the second experiment. The results showed that substituting as much as 10.08% DM of fresh forage uses grass silage does not affect the feed intake (11.56-11.98 Kg DM/head/day), Feed Digestibility (59.37-63.45%), milk protein-production (0.36-0.37 Kg/head/day), milk fat-production (0.54-0.58 Kg/head/day), daily milk production (12.36-12.67 Kg/head/day) in the first experiment. Feed intake (Kg DM /head/day), milk protein-production (Kg/head/day), milk fat-production (Kg/head/day), and daily milk production (Kg/head/day) increase with added 15.03%S-PKM-2.03%GS in the second experiment.

Abstract

Penelitian ini bertujuan untuk mengetahui hubungan antara total digestible nutrient (TDN) dengan komposisi nutrien hijauan (rumput dan legum) dan untuk menentukan prediksi persamaan TDN yang menunjukkan kualitas hijauan pakan tropis. Komposisi nutrien berasal dari data hasil penelitian yang telah dipublikasikan yang terdiri dari 52 hijauan (29 rumput (R) dan 23 legum (L)) meliputi kadar abu, protein kasar (PK), lemak kasar (LK), serat kasar (SK), bahan ekstrak tanpa nitrogen (BETN), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemiselulosa, selulosa dan TDN (%BK) digunakan dalam penelitian ini. Data yang diperoleh dianalisis dengan Korelasi Pearson dan regresi linier berganda untuk menentukan model pendugaan TDN. Model dengan koefisien determinasi dan probabilitas paling tinggi akan divalidasi dengan menggunakan mean absolute deviation (MAD), root mean square error (RMSE), mean absolute percentage error (MAPE). Hasil penelitian menunjukkan bahwa komposisi nutrien dapat digunakan untuk menentukan TDN pada hijauan tropis yaitu pada rumput dan legum. Hal tersebut ditunjukkan oleh nilai MAD, RMSE dan MAPE yang lebih rendah dibandingkan dengan rumus TDN lain. Model pendugaan TDN yang diperoleh yaitu TDNR+L = 49,866 – 3,488 Abu + 0,112 Abu*PK + 0,056 Abu*BETN; TDNR = 49,875 + 0,031 Abu*PK; dan TDNL = 15,212 + 5,084 LK + 0,070 Abu*BETN. Berdasarkan hasil penelitian, maka dapat disimpulkan bahwa model pendugaan TDN dapat diestimasi secara akurat dari komposisi nutrien sehingga dapat digunakan untuk merepresentasikan TDN berdasarkan basis data hijauan tropis. Model pendugaan TDN yang dapat digunakan yaitu TDNR+L dan TDNL.

Abstract

The accuracy of near infrared reflectance spectroscopy (NIRS) depends on the database generated from the conventional wet chemistry (CWC). Currently, the local database of fiber-source feeds for tropical dairy cattle are still limited. The study aimed to compare CWC and NIRS initial database (NIRSID) results, to predict CWC from NIRSID, and to improve the accuracy of NIRS prediction using local database (NIRSLD). Five feeds as sources of fiber (Napier grass, natural grass, corn leaves, corn husk, and rice straw) from 4 areas of dairy cattle farming were used (4 farms from each area). For external calibration, 20 independent Napier grass samples were tested. Samples were analyzed using NIRS and CWC to measure dry matter (DM), ash, crude protein (CP), ether extract (EE), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), and silica (Si) to calculate hemicellulose, cellulose, and lignin contents. The results obtained by NIRSID were compared to those obtained by CWC using T-test. Predictions of CWC from the results obtained by NIRSID were attempted using regressions. The NIRSLD was developed by inputting the CWC value to NIRS spectrums. Internal calibration and validation as well as external calibration, were run. The results showed that NIRSID has low capacity in determining CWC (R2<0.683). Calibration using local database (NIRSLD) improved CWC prediction accuracy (residual predictive deviation (RPD) > 2 except for DM, EE, CF, ADL, and lignin). External validation showed that CWC and NIRSLD were similar in all parameters (p<0.05). The ratios of the standard error of prediction (SEP) to the standard error of laboratory (SEL) were > 2 for CP, CF, and ADF. It is concluded that the local database of NIRS of fiber-source feeds is necessary to improve the prediction accuracy of local dairy fiber-source feeds values using NIRS.
