Abstract

Based on the agricultural production, Indonesia has very high potential to increase rice production through the implementation of adapted and liable technology. The role of non-rice sub sector is also needed to harmonize management in various aspects, in which one of them is livestock sub sector. This management could be done through the development of livestock farming using the rice straw as one of the potential animal feed. The objective of the study was to get a conceptual integrated systems of rice production based on livestock (cattle) development. The estimation of bio-economic for rice straw fermented utilization as animal feed has been done through observation of the cattle biological parameter. An economic approach that has been used in the study was the partial budget analysis including the feed cost per gain (FC/g) and gross margin analysis. The results of the study has shown that FC/g of the cattle from Boyolali and Sumba Ongole (SO) were the most efficient in using the feed compared to the other four cattle. Those were Rp.4600,- and Rp.4995,- per head per day for cattle from Boyolali and SO, respectively. The two types of cattle also reached the gross margin estimation, however SO cattle was slightly less than that of the cattle from Boyolali (Rp.2854,- vs Rp.2897,- ) per head per day. The differences were very much depending on the growth rate of each type of the cattle.   Key words: Feed cost per gain, gross margin estimation, rice straw, beef cattle farming

Abstract

Dry season resulted in lower availability of ruminant feeds with subsequent effects on reduction of sheep productivity; therefore nutritive supplement may be required. The objective of this experiment was to study the effect of supplementation of catalytic substrate consisting of gelatinized sago, ammonium sulfate, Co and Zn on the sheep rumen characteristics and its microbial population. Forty lambs with an average live weight of 13 kg were divided into 8 blocks to test 5 feeding treatments. The treatments were feeding low quality forage without supplement (R1), R1 plus catalytic supplement at 10% of ration (R2), 20% (R3), 30% (R4) and a positive control treatment (R0 = R1 + soybean meal). Parameter measurements included rumen pH, ammonia, VFA and microbial population. It was observed that the rumen pH ranging from 6,06 (R1), 6,15 (R2), 6,45 (R4), 6,58 (R3) and 6,85 (R0). The rumen concentrations of ammonia were 5,83 mM (R3), 6,01 mM (R4), 6,35 mM (R2), 8,30 mM (R0) and 9,36 mM (R1) with total volatile fatty acid concentration ranging from 154, 88 mM (R1), 163,70 mM (R2), 180,89 mM (R0), 188,79 mM (R4) and 194,71 mM (R3). Population of rumen bacteri for R3 was 6,09 x 109 cell/ml, which was greater than RO (5,57 x 109 cell/ml), R1 (4,36 x 109 cell/ml), R2 (4,15 x 109 cell/ml), R4 (5,60 x 109 cell/ml), while protozoa R3 (2,59 x 106 cell/ml), was lower than RO (3,51 x 106 cell/ml) R1 (5,49 x 106 cell/ml) R2 (5,61 x 106 cell/ml) R4 (3,31 x 106 cell/ml). Catalytic supplement at 20% of ration (R3) resulted in a normal rumen concentration of ammonia and pH, and increased VFA concentration. It was concluded that catalytic supplement at 20% of ration was the appropriate level for optimal rumen characteristics.Key words : catalytic supplement, minerals, microbes, rumen, sheep

Abstract

To determine the effect of additional protected protein and energy on intake and digestion in lambs, a trial was conducted using 36 young sheep (average body weight 24 .8 _+ 1 .7 kg) in a completely randomized design . Combination of three levels of protected protein (0, 10 and 20%, based on the dry matter of the concentrate offered) and three levels of protected energy (0, 5, 10%, based on the dry matter of the concentrate offered) were added into concentrate diet and fed to growing sheep. Results showed that different levels of feed additive did not affect (P>0 .05) intake of dry matter, organic matter, neutral detergent fiber, acid detergent fiber and metabolizable energy, with average of 76 .3 g, 68.9 g, 31 .2 g, 16 .79 g and 0.75 MJ /kg BW0.75 respectively . Level of protected protein gave significant (P<0 .05) respons on crude protein intake (7 .4 vs 8.7 vs 9.8 g/kg BW0.75) . Combination of protected protein and energy did not affect animal ability to digest the nutrient effectively. A mixtures of 20 % protected protein and 5 %energy addition into concentrate diet increased average daily gain (ADG) as much as 100 g. It was also found that for every gram ADG needs 42.2 kJ metabolizable energy .   Key words : Protein, protected energy, sheep

Abstract

The effects of inorganic and organic Zn, Cu and Mo supplementation to the in vitro digestibility of Elephant grass were studied in this trial. The in vitro trial used the TILLEY dan TERRY method modified by VAN SOEST with the incubation of the grass for 48 hours in sheep rumen liquor medium. Mineral added as fonn of organic and inorganic. The treatment of mineral inorganic supplementations were by adding single e1emen Cu, Zn and Mo and its combination. Mineral added was Zn (as chloride and sulphate salts) 5 ppm, Cu (sulphate salt) 0,1 ppm dan Mo (molybdate salt) 5 ppm, with 4 replicates. Meanwhile the organic minerals added were in the proteinate fonns. Parameter measured were in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD), pH, VF A total and NH3. Statistical analysis was done by using Complete Split splitsplot design. The supplementation increased pH value, VFA total, IVDMD and IVOMD value (P<0,05) and decreased NH3 value. The highest IVDMD and IVOMD values obtained at the mixture supplementation of mineral Zn (as Zn S04), Cu and Mo, from 58,31 became 69.73% and 52.22 became 62.55% respectively for IVDMD and NOMD. pH value increased from 6.48 to 7.05 and ammonia content decreased from 1,17 to 0,14%. The organic mineral supplementation, en-proteinate dan Zn-proteinate showed that the adding of Zn, Zn and Mo, Zn and Cu also the combination of Zn, Cu and Mo, resulted in IVDMD values as 70.29; 69.97, 64.12 and 63.93%. Further more IVDMD value at the supplementation of Cu and the combination of Cu and Mo were 65.08 and 60,49%. It can be concluded that the supplementation of minerals in the form of inorganic or organic could improve the IVDMD values   Key words: Three element, in vitro digestibility, sheep

Abstract

High producing ewes required high amounts of energy, which can not be met through feeding conventional ration. Therefore, supplementing energy should be done, especially protected-energy. The purpose of this study was to determine the effects of additional of protected fat/energy on the consumption of ration and the performance of ewes and lambs. Thirty-four local ewes were randomly allotted to four levels of by-pass energy groups, in which parts of energy content in the concentrate was replaced with rumen-protected fatty acids in the proportion of 0 (R1), 5 (R2), 10 (R3), and 20% (R4). Consumption, nutrient digestibility and animal performance (ewes and lambs) were determined by standard procedures. Results showed that the daily dry matter intake during pregnancy (g/kg BW0.75) did not differ among diet (72.1 + 2.56). The crude fibre intake varied slightly between treatment (P>0.05), those being slightly lower intake on the highest replacement of energy content in concentrate diet (R4). Dry matter digestibility were 52.4 + 0.24, 52.1 + 0.30; 51.8 +0.28; and 51.3 + 0.81 in groups R1, R2, R3, and R4, respectively, which were non-significantly different from each other. These results confirmed that the by-pass energy sources replacements did not affect rumen fermentation. The same tendency was also found for crude protein digestibility (P>0.05) i.e. 60.1; 61.8; 61.2; and 60.2 for R1, R2, R3, and R4 respectively. The average daily gain of ewes during gestation period was affected (P<0.05) by by-pass energy replacement and the effect was linear with increasing by-pass energy replacement. Significant difference was not found in the total birth weight of lambs and among dietary treatments. Lambs growth rate during the first 8 week of lactation was the highest on ewes fed diet containing the highest amount of by-pass energy sources (R4). It can be concluded that by-pass fatty acids can be used in ewes’ ration without affecting rumen fermentation and gave a positive respons to animal performance.   Key words: By-pass energy, ewes ration, gestation and lactating phase

Abstract

Preparation of anaerobic-rod cellulolytic bacteria with coating technique has been conducted. Steps of the processes involved were cultivation, coating, evaporation, and drying. Coating agent used was Gum Arabic, and drying techniquesconducted were freeze drying and sun drying. pH of culture media was firstly optimized to obtain the maximal population ofbacteria. Both coated and uncoated preparates were subjected to drying. Morphological and Gram type identifications showed that uncoated preparate dried with freeze drying is not contaminated (ie. all bacteria are rod shape with Gram-negative type) while the one dried with sun drying is not morphologically pure (ie. containing of both rod and coccus shapes with Gram negative and positive). The coated preparates dried by both freeze and sun drying, were not contaminated (ie. all are rods with Gram-negative). The coating and drying processes decreased viability of preparates significantly. However, the decreasing of viability of coated preparate are lower than uncoated preparate (ie. 89 vs. 97%). Total count of bacteria in sun-drying coated preparate are higher (P<0.05) than the uncoated preparate (ie. 3.38 x 1010 vs.  1.97 x 1010 colony/g DM). Activity of sun-drying coated preparate to digest elephant grass and rice straw was higher (P<0.01) than the sun-drying uncoated preparate with the in vitro DMD values were 42.7 vs. 35.5% for elephant grass substrate and 29.3 vs. 24.6% for rice straw substrate. Therefore, it is concluded that coating technique has a positive effects on the preparation of rumen bacteria.   Key words : Anaerobic bacteria, coating, drying

Abstract

Studies regarding the use of living microorganisms as supplement have been done in the last two decades to improve digestion process in the rumen. Many factors affect the use of the supplement, such as ration composition and physiological status of the animals. Materials used in this experiment are Aspergillus oryzae (AO) derived from ‘tauco’ (salty fermented soybean) and soybean sauce processing factories located in Bogor, Cianjur, and Sukabumi districts (15 sources), and also AO culture collections of the Indonesian Res. Inst. for Anim. Prod. (2 strains) and one strain from Indonesian Res. Inst. for Vet. Sci. in Bogor. The fungus was first isolated in potato dextrose agar (PDA), incubated at room temp. (26-300C) for 5 days for purification. The AO from PDA then inoculated into cooked rice enriched with mineral mix, oven-dried (40-450C), then ground and kept in refrigerator as a stock culture for further use. To produce more AO (scaling-up), the culture is inoculated in two basal media, i.e. soybean meal and ‘onggok’ (tapioca processing waste) enriched with mineral mix, dried and ground, then kept in refrigerator as A. oryzae fermentation culture (AOFC). Ground-dried King grass was used for in vitro digestion trials using sheep rumen fluid, which was not supplemented (control) or supplemented with the AOFC (10% w/w) from various sources. Three best AOFC (by origin) were chosen and used for further digestion study. The study was run using 2 (media) x 3 (AOFC origin) factorial experiment based on a completely randomized design and Duncan’s MRT was applied to test differences among treatment means. Preliminary results indicated of the AOFC-SP66, -F172, and -CT4 used, the best AOFC was SP66, as it increased (P<0.05) fiber (NDF) digestion (10.5% better than the control). Total VFA productions were similar, but acetate content in the rumen fluid was lowered (P<0.05), while propionate and butyrate levels were alleviated (P<0.05) by the AOFC-SP66. Ammonia content was not affected by addition of AOFC. No differences were detected on digestion parameters between the two media used for AO cultivation, therefore, it is suggested to use ‘onggok’ for producing AOFC in large scale. VFAs composition pattern suggests that AOFC was more suitably used for meat rather than for milk production. Key words: Fungus, King grass, digestibility, rumen fluid

Abstract

Utilization of yeast and or filamentous fungi as feed additive to ruminants has been of interest since the late 1980’s. Two fungi species have been commercially produced in the United States, (1) Yea-Sacc containing living cells of Saccharomyces cerevisiae and (2) Amaferm bearing Aspergillus oryzae fermentation extract. It has been demonstrated and proven that the cultures can enhance rumen development and function in young ruminants. This paper concerns the use of Aspergillus oryzae fermentation culture (AOFC) as feed additive for young-growing male ‘Garut’ sheep. The A. oryzae was cultured in a media made of mineral-enriched ‘onggok’ flour, a material of tapioca processing waste. The AOFC was prepared gradually by incubating the fungus at room temperature (26 – 300C) for 5 days, dried at 400C and ground. The AOFC was added to a commercial concentrate (GT-03) at 0, 5 and 10% (w/w) levels, as treatment C0 (control), C1, and C2, respectively. Fifteen growing ‘Garut’ sheep were used and the concentrate feed treatments were randomly allotted based on a randomized block design. Drinking water was available at all time. The amount of feed offered (chopped King grass and concentrates) and their refusals were weighed daily and live-weight of sheep was measured once a week in the morning. Daily feces was collected and weighed in the last 10 days of the 14-week experimental period. All feed and fecal samples were analyzed for dry matter, crude protein, total fiber (NDF), and ash. AOFC supplementation resulted in higher weight gains (P<0.05), which were 94.81; 122.08; and 140.52 g/d for C0, C1, and C2 treatments, respectively. Dry and organic matter, as well as protein intake was also significantly increased by inclusion of AOFC into concentrate diet (P<0.05). The increment in nutrient intake was from increased consumption of concentrates, and not from King grass, however, there was no effect of AOFC supplementation on feed efficiency.   Key words: A. oryzae, sheep, gain, efficiency

Abstract

The effect of supplementation of graded levels of Zn-bio-complex in concentrate on the growth of young sheep was studied. Fourty young Thin Tailled sheeps were devided into 4 groups of Zn-bio complex treatments. Zink-bio-complex was produced by IRIAP’s laboratory. King grass powder (CP = 10.4%) and concentrate (CP=15.5%) were given as a basal diet. King grass powder and drinking water were given ad libitum. The concentrate was given daily at 200 g h-1d-1 supplemented with 0 mg Zn kg-1 of DM (R1), 50 mg Zn kg-1 of DM (R2), 100 mg Zn kg-1 of DM (R3), and 200 mg Zn kg-1 of DM (R4). The initial live weight of sheep was 11.99 ± 0.17kg h-1. Live weight were measured fortnightly and feed consumption were measured daily. The experiment was carried out for 12 weeks with 4 weeks prior adaptation periods. Data obtained were analyzed statistically based on Completely Randomized Design. The results of experiment showed that the supplementation of Zn-bio-complex improved the live weight from 57.60 g h-1d-1 (R1) to 85.47, 72.14 and 67.86 g h-1d-1 with the feed conversion ratio improvement from 11.9 (R1) to 8.0, 9.6 and 10.5 for treatment R2, R3 and R4 respectively (P<0.05). The graded level of Zn-bio-complex did not affect daily feed intake which was 687, 686, 695 and 711 g h-1d-1 (P>0.05) for R1, R2, R3 and R4, respectively. It can be concluded that the supplementation of Zn-bio-complex at the level of 50 mg Zn kg-1 in daily concentrate resulted in the best response on live weight gain and feed conversion ratio of young sheep.
