Abstract

The objective of this experiment was to evaluate the effect of drought stress and mycorrhizal inoculation on physiological adaptation and biomass production of Macroptilium bracteatum. This experiment was arranged in completely randomized design with four treatments: M0 (no AM + watered), M1 (AM + watered), M2 (no AM + drought), and M3 (AM + drought) with three replicates. The observed variables were soil water content, leaf water potential, leaf relative water content, leaf proline, leaf water soluble carbohydrate (WSC), root and shoot dry weight. Data were analyzed by ANOVA and differences between treatments were tested by DMRT. Drought treatments (M2 and M3) significantly (P < 0.05) decrease soil water content, leaf water potential, leaf relative water content and increased the leaf proline content. The result in root and shoot dry weight appear that M1 treatment was significantly different (P < 0.05) with treatment M0, M2, and M3. For leaf WSC, M0 and M2 treatments were significantly different (P < 0.05) with treatment M1 and M3. It is concluded that mycorrhiza inoculation was more effective on M. bracteatum, in drought stress. One mechanism of drought resistance of M. bracteatum is the accumulation of osmotic compounds proline. Therefore, proline can be used as an indicator of drought resistance in leguminous plants.   Key words: mychorriza, drought stress, Macroptilium bracteatum, proline, water potential

Abstract

A field experiment on fodder legume Indigofera sp. was conducted to investigate the effects of foliar fertilizer concentration on forage yield and quality, and to identify optimum concentrations among the fertilizer treatments on herbage yield, chemical composition (CP, NDF, ADF, minerals), and in vitro dry matter (IVDMD) as wll as organic matter (IVOMD) digestibility in goat&acute;s rumen. Randomized block design was used for the six concentration of fertilizer treatments; control, 10, 20, 30, 40, and 50 g/10 l with 3 replicates. Leaves were sprayed with foliar fertilizer at 30, 34, 38, and 42 days after harvest. Samples were collected at 2 harvest times with 60 days cutting interval. Application of the foliar fertilizer up to 30 g/10 l significantly increased  herbage DM yield, twig numbers, tannin, saponin, Ca and P content, as well as herbage digestibility (IVDMD and IVOMD). The lower and higher concentration of foliar fertilizer resulted in lower value of those parameters, but NDF and ADF contents had the opposite patterns. The optimum level of foliar fertilizer that resulted the highest herbage yield and quality was 30 g/10 l, and the highest in vitro digestibility and Ca concentration was 20 g/10 l.   Key words: Indigofera, foliar fertilizer, tannin, saponin, digestibility

Abstract

An investigation on growth behavior parameters and its dynamic pattern of signal grass (Brachiaria humidicola) grown under influence of inorganic and organic nutrient supply was conducted during period of wet and early dry seasons in 2004. Five sets of treatments consisted of control (P0), mulch originated from pasture weed biomass (Chromolaena odorata) (PC), animal dung (PF), combination of mulch and dung (PC+F) and inorganic fertilizer (PA) were applied to one year existing signalgrass plots. Block randomized design with 4 replications was used in this experiment. The results showed that application of PA produced the highest length of stolons, node and tiller numbers. There was an improvement of growth by application of PC, PF and PC+F, but at lower level than those of PA. Application of PA caused short growth period (6-8 weeks) to reach maximum length of stolon, node and tiller numbers, but less persistent (10-12 weeks) if the grass had not been defoliated. On the other hand, application of organic nutrient led to slow growing grass, but it showed more persistent. The application of organic nutrient supply (PC, PF and PC+F) resulted the best growth of signal grass in comparison with control and more persistent than that of inorganic fertilizer (PA).

Abstract

Forages in swamp area consist of grass and legumes that have good productivity and nutrient quality. This research was aimed to evaluate the potency of swamp forage on digestibility and performance of goats. There were 24 local male goats aged 10-12 months with initial body weight of 13.10±1.55 kg, allocated into 6 treatments. Those were control (R0): 60% grass and 40% legumes; (R1): 60% swamp forages and 40% concentrate; (R2): 100% swamp forages; (R3): 100% swamp forage hay; (R4): 100% swamp forage silage; (R5): 100% haylage swamp forages. Results showed that silage treatment significantly increased (P&lt;0.05) consumption and digestibility. Swamp forages could be utilized well by preservation (silage, hay, and haylage). Ensilage of swamp forages increased protein content  from 13.72% to 14.02%, protein intake (74.62 g/d), dry matter intake (532.11 g/d), nitrogen free extract intake (257.39 g/d), with total body weight gain (3.5 kg) in eight weeks and average daily gain (62.60 g/d). It is concluded that ensilage of swamp forages (R4) is very potential to be utilized as forage source for ruminants such as goats.   Key words: body weight, goat, haylage, silage, swamp forage

Abstract

Local buffalo rumen fluid is a source of fiber digesting bacteria. Such bacteria presumably are well adapted to feed stuffs derived from agricultural byproducts with low quality. The purposes of this study were: (1) to isolate the fiber-digesting bacteria from buffalo rumen fluid, (2) to determine the fiber digesting characteristics and adaptability of such bacteria, and (3) to characterize the bacterial diversity.  Rumen fluids for the experiment were collected from buffaloes slaughtered at the Faculty of Animal Science, Bogor Agricultural University abattoir. Fiber-digesting bacteria were isolated using McDougall buffer supplemented with fibrous feed. A factorial experiment was conducted to study characteristics and adaptability of the bacteria using two factors: the type of bacteria and type of feed source of the fiber. Diversity among the bacteria was analyzed using the NTSys2.10 program.Results showed that nine bacterial isolates had a high adaptability to fiber feed based on CMCase. The highest CMCase activity bacteria for Pennisetum purpureum were A9 (11.36±1.70 unit/ml/h), A3 (11.22±0.60 unit/ml/h) and A42 (10.62±1.96 unit/ml/h). CMCase activity of fiber digesting bacteria from buffalo rumen fluid was not correlated with the number of bacteria in the culture. Based on genetic similarity, nine isolates were grouped into five types having similarity≥46%. Key Words: Buffalo Rumen Fluid, Fiber-Digesting Bacteria, Low Quality Forage

Abstract

An analysis of the roles of stakeholders was conducted as a continuity program of Peternakan Sapi Terpadu (PESAT; integrated beef cattle farm) following the coal mining deactivation by PT Kaltim Prima Coal (KPC) of East Kutai, East Kalimantan. The purpose of this study was to formulate stakeholders relation in the future program. The stakeholders involved in this program were PT KPC, local breeders, Sekolah Tinggi Ilmu Pertanian (STIPER; Agriculture Academy) of East Kutai, and the local government of East Kutai. The stakeholders analysis was based on the variables of the importance and influence from every analyzed stakeholder. The analysis model used here was the model introduced by Reed et al. (2009). According to the result of the stakeholders analysis, PT KPC was in the key-player quadrant, which score is 25 in both of the interest and the influencial level,  while the three others, such as, local breeders, STIPER of East Kutai, and the East Kutai Government were in the subject quadrant. Their score were 24 and 7 for Local breeders, 21 and 9 for STIPER of East Kutai, and 16 and 13 for The East Kutai Government.  It means, they had high interest but low influence to the program. The conclusion of this analysis shows that PT KPC is still dominating in the PESAT program management, whereas the three other stakeholders are acting merely as program users that have low involvement in the program management.   Key words: analysis, East Kutai, PESAT, PT KPC, stakeholder

Abstract

This research was conducted to evaluate production, different competition indices and nutritive value of Setaria splendida, Centrosema pubescens, and Clitoria ternatea in monoculture and mix cropping system on peat soil land. The experiment was set up in a randomized complete block design with five treatments and three replications. The five treatments were:  S. splendida sole cropping (SS), C. pubescens sole cropping (CP), C. ternatea sole cropping (CT), S. splendida and C. pubescens mix cropping (SS/CP) and S. splendida/C. ternatea mix cropping (SS/CT). The DM yield of S. splendida in mixed cropping with C. pubescens increased 43.4% and in mix cropping with C. ternatea increased 15.7% compared to sole S. splendida. The value of land equivalent ratio of SS/CP (LERSS/CP) was &gt;1. The LERSS/CT value was &lt;1.  The crowding coefficient value of S. splendida (KSS) was higher than KCP and KCT. The total value of KSS/CP and KSS/CT were &gt;1. The competition ratio (CR) values of S. splendida in both mix cropping were &gt;1. The agressivity (A) values of S. splendida in both mix cropping were positive. The crude protein, NDF and ADF content of forage were not affected by mix cropping system. In conclusion, mix cropping in peatland do not affect productivity and nutritive value of S. splendida,  C. pubescens, and C. ternatea. S. splendida is more effective in exploiting environmental resources when intercropped with C. pubescens compared to C. ternatea on peatland.   Key words: cropping system, forage, production, quality

Abstract

Buffalo’s rumen bacteria (BRB) are potential in digesting fiber feed. BRB already adapted well with low quality forages and agricultural byproducts. The aim of this study was to determine the effect of buffalo’s rumen bacteria (BRB) consortium inoculated into preweaning Frisian Holstein calves on nutrient digestibility, physiological status, mineral uptake, and blood profile. This study used 14 isolates of bacteria isolated from rumen fluid of four local buffalos. The research units consisted of seven Frisian Holstein calves at two weeks old with the average body weight of 43.6±4.5 kg. Calves were inoculated with 20 mL of buffalo’s rumen bacteria isolates [4.56 x 109 cfu/mL] every morning for 10 weeks. The calves were divided into two groups i.e., three calves received bacterial inoculation and four calves without any inoculation. The variables which were analyzed in the preweaning and weaning period were feed intake, digestibility, average daily gain (ADG), feed conversion ratio (FCR), rumen fermentation characteristics, body weight, physiological status, blood profile, and mineral status. Data were analyzed statistically using t-test. The results showed that inoculation of buffalo’s rumen bacteria into Frisian Holstein calves effectively increased feed intake, characteristics of leukocytes and neutrophils, and cobalt (Co) uptake during the weaning period. Inoculation of rumen bacteria improved rumen pH during preweaning and weaning periods. Inoculation of rumen bacteria also had no negative effects on digestibility, feed conversion (FCR), average daily gain (ADG), and physiological status.Key words: buffalo rumen bacteria, digestibility, physiological status, blood profile, Pennisetum purpureum

Abstract

One of the main constraints in increasing livestock productivity in the tropical region is the scarcity of good quality feed throught the year, particularly during the long-dry season. Being a leguminous tree, Indigofera sp known to be tolerant to dry climate and salinity, should be considered as alternative fodder for ruminant animals. This study is aimed to investigate the productivity and some nutritional quality of Indigofera sp under different interval and hight of defoliation. The experiment was designed in a randomized block of factorial treatments. The factors were interval of defoliation (30, 60 and 90 days) and hight of defoliation (0.5, 1.0 and 1.5 m above ground level). Indigofera sp was planted in 4 x 3 m plots of 36 plots (4 replications) and were harvested at 8 months old. The DM production, chemical composition and in vitro digestibility were measured according to the treatments. The highest DM productivity was (33.25 t ha-1 y-1) at defoliation interval of 90 days and defoliation hight of 1.5 m, and was not different (P &gt; 0.05) from the treatment combination of 60 days defoliation interval and 1,5 m defoliation hight (31.23 t ha-1 y-1). The highest leaf/stem ratio was 2.6 (P &lt; 0.05) in the 30 day defoliation interval across the defoliation hight. The OM content of Indigofera sp was not affected by defoliation treatments and ranging from 884.6 to 906.8 g/kg. The highest NDF and ADF contents were (P &lt; 0.05) in the 90-d defoliation interval and 1.0 m (387.9 and 272.6 g/kg, respectively) and were not different (P &gt; 0.05) for the 90-d defoliation interval and 1.5 m defoliation hight (385.6 and 267.0 g/kg, respectively). The crude protein content was lowest (P &lt; 0.05) in the 30-d defoliation interval across the defoliation hight ranging from 211.2 to 219.7 g/kg, and it was not different between the 60 and 90-d defoliation interval across the defoliation hight (255.0-258.1 g/kg and 230.3-236.0 g/kg, respectively). Defoliation hight did not affect (P &gt; 0.05) the DM and OM in vitro digestibility. They were at the 90-d defoliation interval ranging from 680.2 to 706.8 g/kg and from 668.6 to 686.8 g/kg, respectively across the defoliation hight different. The DM and OM digestibility were not different (P &gt; 0.05) between the 30 and 60-day defoliation intervals. It is concluded that when planted at low land of wet climate the combination of a 60-d defoliation interval and 1.5 m defoliation hight is an optimum cutting management in utilization of Indigofera sp as foliage for ruminant. Key Words: Defoliation, Nutritive Quality, Productivity, Indigofera sp
