“…Typical CP contents in redbean, groundnut, pigeonpea, cowpea, bambarabean, and mungbean are (mean±sd) 248±15, 297±31, 232±90, 252±22, 198±31, and 258±28 g/kg DM, respectively (FAO, 2016), in which data on CP contents of the beans in the present experiment were within the range reported by FAO. Protein in soybean is known to be easily degraded in the rumen and therefore it is high in the proportion of rumen degradable protein (Maxin et al, 2013;Akbarian et al, 2014). The present study confirmed such finding as shown by the high proportions of protein fraction B1 and B2 in soybean as well as by the high value of CPDe and ammonia concentration in the in vitro incubation of soybean.…”

This experiment aimed to determine nutrient content, protein fraction, and in vitro rumen fermentation of some alternative beans in comparison to soybean. Samples used were napier grass, soybean, redbean, groundnut, pigeonpea, cowpea, bambarabean, and mungbean. Samples were determined for their proximate composition, Van Soest's fiber fraction, and Cornell protein fraction. The samples were subsequently evaluated for their fermentation characteristics and digestibility by using a two-stage in vitro rumen fermentation technique, maintained at 39 o C for 2 × 48 h. The in vitro incubation was performed in three consecutive runs by following a randomized complete block design in which each sample per run was represented by four fermentation tubes. Results revealed that all experimental beans contained high crude protein (CP), i.e. above 200 g/kg dry matter (DM), but only soybean and groundnut had CP contents higher than 300 g/kg DM. Redbean had the lowest crude fiber and acid detergent fiber contents among the beans. Soybean contained high proportion of rapidly degraded CP fraction, but low in slowly degraded and unavailable CP fractions. High proportion of slowly degraded CP fraction was found in redbean and bambarabean. Redbean, pigeonpea, cowpea, and mungbean were better than soybean, groundnut, and bambarabean with regard to DM degradability and DM digestibility values (P<0.05). Concentration of total VFA was the highest in the incubation of redbean. It was concluded that groundnut, redbean, pigeonpea, cowpea, and mungbean have the potency to be used to substitute soybean for ruminant feeding. ABSTRAKPenelitian ini bertujuan untuk menentukan kandungan nutrien, fraksi protein, dan fermentasi rumen in vitro dari sejumlah kacang-kacangan alternatif kacang kedelai sebagai pakan ternak ruminansia. Bahan pakan yang digunakan dalam penelitian ini adalah rumput gajah, kacang kedelai, kacang merah, kacang tanah, kacang gude, kacang tunggak, kacang bogor, dan kacang hijau. Analisis komposisi proksimat, fraksi serat Van Soest, dan fraksi protein Cornell dilakukan pada bahan. Bahan kemudian dievaluasi secara in vitro dengan menggunakan teknik fermentasi rumen dua tahap pada suhu 39 o C selama 2 × 48 jam. Inkubasi in vitro dilakukan dalam tiga ulangan berdasarkan rancangan acak kelompok (masing-masing diwakili oleh empat tabung fermentasi). Hasil penelitian menunjukkan bahwa semua kacang-kacangan mengandung protein kasar (PK) yang tinggi, yakni lebih dari 200 g/kg bahan kering (BK), namun hanya kacang kedelai dan kacang tanah yang lebih tinggi dari 300 g/kg BK. Kacang merah memiliki kandungan serat kasar dan serat deterjen asam yang paling rendah di antara kacang-kacangan yang diuji. Kacang kedelai mengandung proporsi fraksi PK mudah terdegradasi yang tinggi, namun rendah fraksi yang lambat terdegradasi dan yang tidak tersedia. Fraksi PK lambat terdegradasi yang tinggi terdapat pada kacang merah dan kacang bogor. Kacang merah, kacang gude, kacang tunggak, dan kacang hijau memiliki degradasi dan kecernaan BK yang lebih tinggi ...

“…With regard to protein digestibility, greater CPD found in soybean than that of redbean is apparently due to the different nature of protein in both beans. Soybean protein has been characterized by its high proportion of degradable protein in the rumen (Maxin et al, 2013;Akbarian et al, 2014) whereas redbean protein is rich in slowly degraded fraction (Jayanegara et al, 2016a). These facts explain the difference of CPD between soybean and redbean.…”

The objective of this study was to investigate the effect of drying temperatures on chemical composition, rumen fermentation, and digestibility of soybean and redbean (in vitro). Soybean and redbean were dried in an oven set at four different drying temperatures: 50, 60, 70, and 80 o C for 24 h in three replicates. The dried samples were then grilled and used further for chemical composition determination (proximate analysis, Van Soest analysis, and protein fraction) and in vitro rumen fermentation assay. Parameters measured in the in vitro assay were gas production, digestibility, pH, ammonia, and volatile fatty acids (VFA). Data obtained were analyzed by using analysis of variance and a posthoc test namely Duncan's multiple range test. Results showed that neutral detergent insoluble crude protein (NDICP) content was increased at higher drying temperature (70 or 80 o C) for both soybean and redbean (P<0.05). Similar to NDICP, higher temperature led to a greater acid detergent insoluble crude protein (ADICP) of soybean as well as those of redbean (P<0.05). Higher temperature decreased gas production rate (GPR) of both beans (P<0.05). Drying of soybean at 70 or 80 o C decreased crude protein digestibility (CPD) of soybean more than those of dried at 50 or 60 o C (P<0.05). Higher drying temperature resulted in a lower NH3 concentration of both beans (P<0.05). In conclusion, drying temperature at 50 or 60 o C was considered to be safe to maintain the nutritional quality of soybean and redbean.

“…Higher secretion of gut peptides may induce reduced gut motility (Allen 2000) which can cause a reduction in DMI by decreasing meal size and a decrease in time spent rumination by decreasing rumination duration (Harvatine and Allen 2006). Although the inconsistent effect of feeding SBM (as rumen degradable source of protein with diminished oil content) vs. roasted SB (RSB) or extruded SB (ESB); both as rumen undegradable source of protein containing higher amounts of unsaturated oil) on DMI has been reported in some research studies (Amanlou et al 2012;Akbarian et al 2014;Giallongo et al 2015), there is no available published data, to the best of our knowledge, to report feeding and chewing behaviour of cows fed RSB, ESB and/or their blends. Therefore, investigation of feeding behaviour when cows are fed diets containing heat processed SB products is required to clarify regulation mechanism(s) for feed intake.…”

“…Heat treated SB (fed at more than 10% of dietary DM) has been variable effect on DMI in previous studies. Some studies reported positive (Anderson et al 1984;Giallongo et al 2015) or negative effects (Akbarian et al 2014), whereas other investigators showed no effects on feed intake (Guillaume et al 1991;Bailoni et al 2004;Amanlou et al 2012). It remains unclear from above mentioned studies that how meal pattern (including meal size and inter-meal interval) is influenced when heat treated SB products are fed to dairy cows.…”

The objective of this study was to evaluate the effects of roasted soybean (RSB), extruded soybean (ESB) and their equal blend (RSB þ ESB) compared with soybean meal (SBM) on nutrient intake, feed preference, meal and rumination patterns, feeding and chewing behaviour and rumen fermentation characteristics of mid-lactation dairy cows. Eight Holstein dairy cows were used in a replicated 4 Â 4 Latin square design with four 28-d periods. Cows received one of the four following experimental diets: (1) 13.88% of diet dry matter (DM) as SBM; (2) 15.22% of diet DM as RSB, (3) 15.55% of diet DM as ESB and (4) 7.69% RSB plus 7.69% ESB (RSB þ ESB). Each experimental period consisted of a 21-d diet adaptation period and a 7-d data collection period. Meal patterns, including meal size and inter-meal interval, were not affected by the experimental diets and thereby DM intake was not different among diets. Sorting index was not different across dietary treatments but intake of particles retained on 1.18-mm sieve and on pan increased and decreased in both SBM and ESB as compared with RSB and RSB þ ESM, respectively. Total time spent eating and ruminating and rumen volatile fatty acid concentrations were unaffected by dietary treatments. Feeding processed soybean instead of SBM had minimal effects on sorting behaviour and meal patterns and thereby no changes in feed intake occurred. Finally, RSB and ESB and their equal blend had a similar effect on feed intake and chewing behaviour of mid-lactation Holstein cows. HIGHLIGHTS Feeding processed soybean products had the minor effect on feed intake and can be considered as alternative feedstuffs when the price is competitive.
