The feed quality of a variety of native shrub and herbaceous legume species from the Riverina area of southern New South Wales was determined to provide an indication of their potential use in livestock grazing systems. Fifteen species were sampled from each of two locations (chiefly low fertility roadsides or travelling stock reserves) at four times within a 12-month period viz. August, November, February and May according to the most likely plant parts to be consumed by grazing animals for each species. Digestibility was estimated using an in vitro rumen fluid digestion assay and crude protein was estimated from nitrogen analysed using the Dumas combustion method. Digestible organic matter in the dry matter (DOMD) was greater than 550 g/kg dry matter (DM) for seven of the native legume species and was highest for Daviesia spp. (D. latifolia 696.2 ± 15.0, D. leptophylla × latifolia 642.5 ± 15.1 and D. leptophylla 622.7 ± 15.4), Glycine spp. (G. clandestina 628.2 ± 18.1, G. tabacina 621.9 ± 28.0 and G. canescens 580.4 ± 25.4) and Indigofera australis (617.8 ± 15.3). Crude protein content was greater than 80 g/kg DM for all species analysed, suggesting that these plants are able to fix nitrogen under low phosphorus fertility conditions. Studies examining grazing management as well as nitrogen fixation and nitrogen transfer to companion grasses are required in order to optimise the management of these plants in grazing systems.

This study was carried out to determine chemical composition and in vitro dry matter and organic matter digestibility of range plant species of the area. Samples were collected from range lands at full maturity stage, dried under shade and subjected to chemical analysis and dry matter and organic matter in vitro digestibility for Vigna sunhum, Andropogan gayanus, Pennisetum Pedicelatum, Shoenfeldia gracilis and Stylothanis flavicans were determined. The data was analyzed via analysis of variance and differences among means were determined using Least Significant Difference (LSD) test. The results showed that the legumes (Vigna sunhum and Stylothanis flavicans) were significantly higher (P≤0.01) in their crude protein content and the percentage of crude protein respectively was 13.4% and 10.00% while the grasses were significant (P≤0.05) higher in Crude Fibre (CF), ash, Acid Detergent Fibers (ADF) and Neutral Detergent Fibers (NDF). Crude fiber % values were 41.78, 43.37 and 46.07% for Pennisetum Pedicelatum, Andropogan gayanus and Shoenofeldia gracilis, respectively. The acid detergent values were 53.85, 47.74 and 53.39 for the three weeds. (P≤0.05), while the ratio of neutral detergent was significantly higher (P≤.05) in grasses than in the two legume species; 87.22, 82.35 and 88.99% for the three grasses respectively. Similarly higher in vitro dry matter and organic digestibility coefficients were obtained from legume species than grasses. The study concluded that, the studied grasses were higher in fiber content and lower in their protein content but, legumes grasses (Vigna sunhum, Pennisetum Pedicelatum and Stylothanis flavicans) had high nutritive value and in vitro digestibility which may provide ruminants with the needed protein and energy.

ABSTRAK. Silase gabungan rumput-leguminosa merupakan inovasi yang dapat diaplikasikan untuk menyediakan pakan dan bisa digunakan sepanjang tahun. Kandungan protein silase campuran tersebut dapat mencapai tingkat optimal sebagai pakan konsentrat hijau (green concentrate). Penelitian ini bertujuan untuk mengevaluasi kualitas, karakter fermentasi dan kecernaan in vitro silase campuran sorgum (Sorghum bicolor (L.) Moench) and gamal (Gliricidia sepium) dengan menambahkan dosis asam laktat yang berbeda. Silase dibuat dengan mencampur bahan penyusun yang terdiri dari sorgum dan daun gamal dengan perbandingan 1:1 dan penambahan asam laktat konsentrasi 20% (v/v). Penelitian terdiri atas 3 perlakuan yaitu; A0: (kontrol) tanpa penambahan asam laktat, A1: penambahan asam laktat sebanyak 2% (b/v), A2: 2,5% (b/v), dan A3: 3% (b/v) dengan 4 ulangan tiap perlakuan. Proses ensilase menggunakan cairan rumen kambing selama 21 hari. Parameter penelitian yang diamati adalah kualitas silase dan kecernaan in vitro. Hasil penelitian menunjukkan bahwa dosis penambahan asam laktat sebanyak 2% menghasilkan silase paling optimal dengan pH (3,94), bahan kering (26,62%), dan nilai Fleigh (100,89), namun tidak berpengaruh terhadap kandungan protein kasar, kecernaan bahan organik, kecernaan bahan kering dan kecernaan protein kasar. Kesimpulan pada penelitian ini adalah penggunaan asam laktat organik dengan dosis 2 hingga 3% (b/v) konsentrasi 20% (v/v) mampu meningkatkan karakteristik, kualitas fermentasi tetapi tidak mempengaruhi nilai KcBK, KcBO dan KcPK silase campuran sorgum stay green (Sorghum bicolor (L.) Moench) and gamal (Gliricidia sepium).  (Quality evaluation, fermentation characteristic and in vitro digestibility of stay green sorghum-Gliricidia sepium mix silage on different level of lactic acid utilization) ABSTRACT. The grass-legume combined silage is an innovation that can be applied to provide feed and can be used throughout the year. The content of the mixed silage protein can reach optimal levels as a green concentrate feed. This study aims to evaluate the quality, fermentation characteristics and digestibility of in vitro silage of a mixture of sorghum (Sorghum bicolor (L.) Moench) and gamal (Gliricidia sepium) by adding different doses of lactic acid. Silage is made by mixing a constituent consisting of sorghum and gamal leaves in a ratio of 1: 1 and the addition of lactic acid concentration of 20% (v / v). The study consisted of 3 treatments namely; A0: (control) without the addition of lactic acid, A1: addition of 2% (w / v) lactic acid, A2: 2.5% (w / v), and A3: 3% (w / v) with 4 replications each treatment. The ensilage process used goat's rumen fluid for 21 days. The research parameters observed were silage quality and in vitro digestibility. The results showed that the addition dose of lactic acid as much as 2% produced the most optimal silage with pH (3.94), dry matter (26.62%), and Fleigh value (100.89), but had no effect on crude protein content, digestibility organic matter, digestibility of dry matter and digestibility of crude protein. The conclusion of this study is the use of organic lactic acid with a dose of 2 to 3% (w/v) concentration of 20% (v/v) can improve the characteristics, quality of fermentation but does not affect the value of KcBK, KcBO and KcPK silage stay sorghum mixture green (Sorghum bicolor (L.) Moench) and gamal (Gliricidia sepium).

Abstract Study was conducted to determine the adaptability of ryegrass to the ration of ruminants in central region of Turkey. Both ryegrass and alfalfa were planted in Cankiri and Corum cities which are located in similar geographic and climatic conditions. Forage samples were obtained during second, third and fourth harvesting times. in each sample, dry matter (DM), crude fat (EE), crude protein (CP), crude ash (CA), crude cellulose (CS), acid detergent fiber (ADF) and neutral detergent fiber (NDF) levels were determined based on AOAC methods. Metabolizable Energy levels of both ryegrass and alfalfa were calculated. In vitro disappearance of dry matter was measured by incubation of dacron bags in rumen fluid for 72 hours in Ankom® daisy incubator and extent of disappearance were determined. Generalized linear model was applied to analyze data and means were separated by using LSD. Although dry matter levels were similar (P > 0,05), ash and fat levels were significantly higher in ryegrass than those in alfalfa (P < 0,05). Additionally, as it was expected, crude protein content of ryegrass was significantly lower than that of alfalfa (P < 0,05). NDF contents of both feeds were similar and ADF levels of alfalfa were slightly higher in only second harvest date. Metabolizable energy levels of ryegrass in all harvested times were statistically higher than those in all harvested dates in alfalfa (P < 0,05). DM disappearance of ryegrass was significantly higher than that of alfalfa (P < 0,05). In conclusion, ryegrass may have some advantages in regions with limited forage sources. Additionally it may be alternative or substitute to the traditional small grain forages. Further research needed to show those advantages of ryegrass in nutrients to extrapolate consumption preferences or performance of beef or dairy cattle.

The present factorial experiment tested the thawed rumen fluid from frozen rumen contents against fresh rumen fluid from the same slaughtered cattle to estimate in vitro degradation of rapeseed meal (RSM) and grass nuts (GN) as two contrasting feeds at various times. Fresh rumen fluid showed higher (P &lt; 0.05) in vitro dry matter (DMD) and crude protein (CPD) degradation than the thawed rumen fluid at most incubation times. Significant differences (P &lt; 0.05) were found between fresh and differently prepared thawed rumen fluids for mean degradation constants (a, b, c) and effective degradability (P<sub>0.02</sub>) of feeds. While the thawed rumen fluids had lower (P &lt; 0.01) degradation than the fresh rumen fluid, their degradation values correlated very well (R<sup>2 </sup>&ge; 0.95) with those for the fresh rumen fluid. It appeared that the thawed rumen fluid can be used to predict in vitro degradation of the selected feeds when frequent access to slaughtered or fistulated animals is restricted. Nevertheless it would be vital to improve the activity of thawed rumen fluid prior to testing its suitability for numerous feeds before recommending its routine use to estimate degradation of ruminant feeds. &nbsp;

The amaranth plants showed high potential feed value as forage for ruminants. An in-depth study of this plant, particularly in cattle, will help extend its utilization as an alternative protein and fiber feed source in cattle feeding. In this study, the nutrient compositions of three different species of amaranth, Amaranthus caudatus L., Amaranthus cruentus L., and Amaranthus hypochondriacus L.—two varieties for each species, A.ca 74, A.ca 91, A.cu 62, A.cu 66, A. hy 30, and A. hy 48—were evaluated. The in vitro technique was used to evaluate the fermentation characteristics such as total gas production, total volatile fatty acids (VFA) concentration, pH, and ammonia concentration of the rumen fluid. Moreover, the effective degradabilities of dry matter (EDDM) and crude protein (EDCP) of the amaranth forages were determined through in situ bag technique. The amaranth forages: A. caudatus, A. cruentus, and A. hypochondriacus showed better nutritive value than the locally produced forages in Chungcheong province of Korea. The CP of the amaranth ranged from 11.95% to 14.19%, and the neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents ranged from 45.53% to 70.88% and 34.17% to 49.83%, respectively. Among the amaranth varieties, A. hypochondriacus 48 showed the most excellent ruminant feed nutrient quality (CP, 14.19%; NDF, 45.53%; and ADF, 34.17%). The effective degradabilities of dry matter (EDDM; 33–56%) and crude protein EDCP (27–59%) of the amaranth were lower compared to other studies, which could be due to the maturity stage at which the forages were harvested. Nonetheless, A. hypochondriacus 48 showed the highest EDDM (56.73%) and EDCP (59.09%). The different amaranth species did not differ greatly in terms of total VFA concentration or molar proportions, total gas production, or ammonia-N concentration. The high nutrient composition, and highly effective degradability of dry matter and crude protein, coupled with the favorable fermentation characteristics, suggest that the amaranth forages showed good to excellent feed quality for cattle.

Abstract A study was conducted to evaluate effects of increasing concentration of food grade glycerol on rumen environment and nutrient digestibility. Three ruminally cannulated Jersey steers were used in this study. The study was conducted from March to May 2019. Experimental design was a 3x3 Latin square with a 2wk adjustment period followed by a 1wk collection period. Diet was coastal bermudagrass hay based. Different forage types were introduced in the incubation process to evaluate digestibility. Glycerol was administered once a day at 0, 15, or 20% of DMI (dry matter intake). dNDF (digestible NDF) and dDM (digestible dry matter) was determined using an ANKOM Daisy II incubator inoculated with 200g fresh rumen fluid and incubated for 12, 24, 48 and 72 h at 39°C. Each vessel contained ground forage samples in filter bags in triplicate. After incubation, filter bags were rinsed with cold water and dried for 24h in a 55°C forced air oven. Data were analyzed using the Proc MIXED procedure of SAS version 9.4. There was no difference dNDF in effect of different levels of glycerol between forage types by diet. But a numerical tendency was observed that dNDF was decreased at 20% inclusion rates in comparison to 0 and 15% inclusion of glycerol in the diet. Neither steer nor run was significantly different in the study. However as expected digestibility over time was significantly different (P &lt; 0.001). A significant increase was observed in DMI with the increased levels of glycerol in the diet (P = 0.003), both the 15% and 20% levels of glycerol increased in DMI in comparison to the control (0%). It appears based on these study results that digestibility may be inhibited, as levels of dietary glycerol increase in the diet and more work needs to be done to find the optimal level of glycerol supplementation.

The effects of early summer and fall cutting managements on two alfalfa (Medicago sativa L.) cultivars were studied over a 3-year period. Removal of the first crop of Saranac and Narrangansett alfalfas at prebud stage, followed by two cuts at the early bloom stage before early September, and a late fall harvest on October 25, produced seasonal dry matter (DM) yields of 7.5–8.6 metric T/ha in the 1st year. Stand deterioration, however, was severe and by the 3rd year, practically all alfalfa had disappeared. Average percent crude protein (CP) in cut 1 was 17.7–21.9 and percent in vitro dry matter digestibility (IVD) 67.4–73.8. Removal of the first cut at bud stage with two subsequent harvests at the early bloom stage also allowed a total of three harvests before early September and resulted in seasonal DM yields of 8.6–8.8 in the 1st year. Although the survival of alfalfa was increased over the managements where cut 1 was at prebud stage, a considerable decrease of alfalfa was still observed in the 3rd year. Under this management, average CP in cut 1 was 15.8–16.3 and IVD 64.1–68.4. Harvesting the first crop at early to midbloom stage and the second crop at early bloom in early to mid-August, followed by third harvest in late October, resulted in good survival with seasonal DM yields of 6.1–10.6. Lower CP and IVD were recorded in cut 1 than in the more intensive managements. Under all managements, average CP in cuts 2 and 3 was 14.9–17.3 and 13.3–19.4, respectively. IVD was 54.5–60.7 in cut 2 and 56.0–64.4 in cut 3.

1. Grass from the same sward was ensiled without additive, with 14.6 g formic acid/100 g crude protein or 10.8 g formic acid and 10.6 g formaldehyde/100 g crude protein. Similar grass was dried and pelleted. Drying or ensiling with the mixture reduced solubility of N in the preserved grass but formic acid increased it, and ensiling without additive increased it even more. Apparent digestibility of N in the rumen of cows tended to decrease with decrease in solubility. Digestibility in vitro of the mixed diet given to the cows, calculated from digestibility of the separate components, agreed well with the values in vivo for diets with silages, but was high for that with dried grass.
