Abstract Degradation properties of protein feed sources such as tropical legumes is very important to match with microbial protein synthesis and by pass protein requirements in dairy cattle ration formulation. However, the information is still limited. This study aims to determine the degradability of dry matter (DMD) and organic matter (OMD) from several legumes in Indonesia using in sacco method. There are 11 types of tropical legumes that are commonly used in dairy cattle ration have been studied, namely acacia, alfalfa, pterocarpus, gliricidia, indigofera, calliandra, butterfly leaf, leucaena, albizia, tamarind, and sesbania. The dried forage mesh samples were put into nylon bags and incubated in the rumen of two fistulated Friesian Holstein bulls for 0, 3, 6, 9, 12, 15, 24, 48, and 72 hours. Parameter observed were degradability of dry matter (DMD), and organic matter (OMD), kinetic parameters, and effective degradation. The data were analysed using descriptive statistic and regression from SAS University software. The result that sesbania and indigofera grouped into highly degradable forage (degradability > 80%), while acacia, albizia, calliandra grouped into low degradable forage (degradability < 50%). From this study it can be concluded that each type of legume has different degradability characteristics using in sacco method.

SUMMARYMilled barley straw, either untreated or treated with 70 g of NaOH/kg straw was supplemented with four levels of urea, namely 0, 6, 12 or 18 g/kg and fed ad libitum to young sheep. For the untreated straw, dry-matter intakes were (g/day) 423, 451, 441 and 463, while the digestibility of organic matter was 458, 467, 490 and 483 g/kg, respectively. For the treated straw, the intakes of dry matter were 355, 402, 531 and 567 g/day and the digestibility of organic matter was 423, 480, 589 and 628 g/kg respectively.The different responses to urea supplementation of treated and untreated straw are discussed in relation to a new system of estimating protein requirements for ruminants put forward by the Agricultural Research Council.

The Uk

Grass silage forms the basal forage for the majority of dairy and beef cattle during the winter indoor feeding period. However its feeding value, as determined by intake potential and digestibility can differ dramatically at farm level as indicated by the Hillsborough Feeding Information System (HFIS). For example, for 7000 silages which were offered to dairy and beef cattle during the 1999/2000 indoor feeding period in Ireland and analysed through the HFIS, dry matter digestibility (DMD) varied from 540 to 830 g/kg DM (Keady, 2000). Many models used to predict feed intake by dairy cattle include a digestibility component (Keady and Mayne, 2000). However some models use DMD whereas others use digestible organic matter digestibility (DOMD). Furthermore commercial laboratories in Ireland measure silage digestibility as DMD while in the UK it is measured as DOMD. To facilitate the use of different models to predict food intake by dairy cattle, often it is necessary to be able to predict DMD from DOMD or vice versa. The present study was undertaken to develop a relationship between DMD and DOMD to facilitate the use of different models for the prediction of food intake when digestibility is available only either as DMD or as DOMD.

The study was aimed at determining the chemical composition, in sacco ruminal dry matter and organic matter degradability of leaves and fruits of tropical condensed tannin rich multipurpose tree species (MPTS). The MPTS studied were Ekebergia capenesis, Ficus sycomorus, Maesa lanceolata, and Rhus glutinosa. Chemical composition of dry matter (DM), crude protein (CP), crude ash (CA), ether extract (EE), crude fibre (CF), neutral detergent fibre (NDF), non-fibre carbohydrates (NFC), and condensed tannin (CT) was determined. In sacco rumen degradability was measured using three rumen fistulated Holstein Friesian-Boran cross steers at 0, 6, 12, 24, 48, 72, and 96 h. The DM and organic matter (OM) degradability data were fitted to the equation Y = a + b(1 &ndash; e<sup>&ndash;ct</sup>). The values for each chemical constituent ranged 5.43&ndash;11.49% (CA), 7.97&ndash;17.06% (CP), 1.57&ndash;31% (EE), 12.20&ndash;27.5% (CF), 5.84&ndash;39.30% (NFC), and 7.2&ndash;16.72% (CT). Ekebergia capensis leaves had the greatest values for slowly degradable fraction (b), effective degradability (ED), and rate of degradation (c) in DM (P &lt; 0.001) whereas E. capensis fruit had significantly the greatest soluble fraction (a), potential degradability (b), and effective degradability (ED) values as compared to the a, PD, and ED values in the fruits of other plants(P &lt; 0.001). Yet in OM degradation kinetics, the greatest and least values of potential degradability (PD) were recorded for F. sycomorus (89.89%) and E. capensis (55.90%) leaves (P &lt; 0.001). Similar to the rapidly soluble fraction a, ED was found to be the greatest in fruits as compared to leaves of the plants (P &lt; 0.001). Generally variation of plant parts led to significant differences in chemical composition, DM, and OM degradability and the degradable parameters. The leaves and fruits recorded more than 60% DM and OM degradability at 24 h, which implied that they were all greatly degradable in the rumen.

Context Ensuring accuracy of feed testing is becoming increasingly important as livestock industries seek to maximise efficiency of producing animal products to meet world requirements. Aim Twenty-four silages were fed to sheep and cattle to test the validity of using sheep-derived digestibility estimates for cattle. Method The silages tested included temperate and subtropical forages, and differed in level of maturity and weed contamination at harvest: several of the forage crops were grown with irrigation. In vivo comparisons were made for digestibility of dry matter (DMD), organic matter (OMD), and organic matter in the dry matter (DOMD) across two experiments. Intake was restricted to 16.5 g/kg liveweight and those silages with low nitrogen (N) contents were supplemented with urea to meet minimum dietary crude protein requirements. Key results DMD, OMD and DOMD ranged from 0.538 to 0.773, 0.550 to 0.810, 0.505 to 0.762 and 0.551 to 0.749, 0.584 to 0.786, 0.539 to 0.702 for cattle and sheep respectively. DMD, OMD and DOMD determined in sheep explained 88.7, 86.3 and 78.4% of the variation of DMD, OMD and DOMD in cattle respectively. In Experiment 1, DOMD was higher in cattle than sheep but for two silages (Silage 1, Subterranean clover: 0.631 vs 0.589; Silage 5, Annual ryegrass/oats, early cut: 0.761 vs 0.702) whereas in Experiment 2 DOMD was lower for cattle than sheep for one silage (silage 21, maize: 0.645 vs 0.691, s.e.d. = 0.019). Conclusions and Implications Since there was no clear trend for sheep to digest higher quality feeds better than cattle or for cattle to digest lower quality feeds better than sheep, we conclude that, at least for silages made from forage, sheep-derived values for digestibility should, in most instances, be applicable to cattle.

ABSTRACTTwo varieties of rice straw, long variety — no. 370 Basmati traditional (L) and short variety — no. PR106 hybrid (S) were separated into botanical fractions giving the proportion of leaf plus leaf sheath, internode, node and chaff (g/kg dry matter) as 633, 247, 83 and 37 for L and 680, 156, 76 and 88 for S, respectively. Samples of whole plants, leaves plus leaf sheaths and internodes were subjected to ammonia treatment. The chemical composition and the rumen degradability of dry matter and organic matter determined by the nylon bag technique were ascertained for treated and untreated samples of whole plants and botanical fractions of plants from both varieties. The ash and silica content were higher in leaf plus leaf sheath, 211 and 102 g/kg for the L and 190 and 67 g/kg for the S, than in internodes, 160 and 29 g/kg for L and 184 and 29 g/kg S, respectively.The potential degradability (a + b) value from the formula p = a + b(−e−ct) for dry-matter loss (DML), organic-matter loss (OML) and degradability of organic matter in dry matter (DOMD) were significantly higher for the S being 622, 659 and 544 g/kg, than for the L being 561, 586 and 500 g/kg, respectively (P < 0·01). The degradation rate too was significantly higher for the S than for the L for DML, OML and DOMD (P < 0·01). The ammonia treatment significantly improved the potential degradability for DML, OML and DOMD for both the varieties and their fractions (P < 0·01).

This study aimed to evaluate the in sacco nutrient degradability of total mixed ration (TMR) silage containing intact and defatted black soldier fly (BSF) larvae. The study evaluated four dietary treatments and six replications. The treatments consisted of control TMR silage without BSF larvae (R1), 20% intact BSF larvae + 80% TMR silage (R2), 20% chemically defatted BSF larvae + 80% TMR silage (R3), and 20% mechanically defatted BSF larvae + 80% TMR silage (R4). Samples were placed in polyester bags and incubated in the rumen in sacco up to 72 h. Nutrient degradability was evaluated for each time point interval. Results revealed that the lowest dry matter degradability (DMD) was found in R1 compared to all treatments (p < 0.05), while the highest DMD was found in R2 (p < 0.05). The highest organic matter degradability was found in R2 compared to R1, R3 and R4 (p < 0.05). Addition of BSF larvae to TMR silage increased the crude protein degradability (p < 0.05). In conclusion, inclusion of both intact and defatted BSF larvae into TMR silage did not have any adverse effects on nutrient profiles and showed a good nutrient degradation values in the rumen.
