AbstractThe aim of this study was to determine the in vitro digestibility and in sacco disappearance of dry matter (DM) and neutral detergent fibre (NDF) in total almond hulls (TAH), pure almond hulls (PAH) or Debris. The TAH were used because there are no data on the effect of debris (non-hull material) on the nutritional value of almond hulls. Twelve samples of commercial almond hulls were used, with one subsample representing the TAH and the other subsample hand sorted to separate the hulls (PAH) from Debris. Gas production and Ankom Daisy method were used to determine in vitro digestibility, while two rumen-fistulated cows were used to measure in sacco disappearance of PAH and TAH. For in vitro digestibility, both PAH and TAH were more digestible and had greater gas production than Debris. The PAH had greater in vitro true digestibility on a DM basis and NDF digestibility at 48 and 72 h compared with TAH. Nonpareil hulls provided greater metabolizable energy (ME) concentration when compared with other almond varieties, with PAH supplying numerically more ME than TAH for both varieties. For in sacco disappearance, PAH had greater DM and NDF disappearance along with a greater rate of disappearance for NDF compared with TAH. This research demonstrated that Debris is highly indigestible; therefore, hulling, agronomic and harvesting practices should be focused on reducing Debris in commercial almond hulls to improve their nutritive value as a feedstuff for livestock.

The effect of processing on proximate, mineral, anti-nutritional compositions, gasproduction characteristics, methane production, predicted metabolizable energy, organic matter digestibility and short chain fatty acids production of Delonix regia seeds incubated with Pennisetum purpureum were determined. Five treatments (T1: mixture of soaked Delonix regia seed and Pennisetum purpureum; T2: mixture of raw Delonix regia seed and Pennisetum purpureum; T3: mixture of roasted Delonix regia seed and Pennisetum purpureum; T4: mixture of boiled Delonix regia seed and Pennisetum purpureum and T5:100% Pennisetum purpureum which serves as control) were designed. In vitro gas production techniques for 24 hours were used to determine the nutritive value of processed 50% Delonix regia seed and 50% Pennisetum purpureum. The crude protein ranged from 13.38 to 15.71g/100g DM among the treatments while crude fibre was between 20.10 and 21.40g/100g DM, ether extract ranged from 1.90 to 3.12g/100g DM and ash 7.77 to 12.34g/100g DM. Calcium ranged from (2.34 - 3.61%), magnesium ranged (2.90 – 3.48%), sodium (2.05 – 2.91%) and phosphorus (0.88 – 1.12%). It was observed generally that T2 recorded the highest among the treatments while the values obtained for the heat treated seeds were lower than the raw. Oxalates ranged between (0.23% - 0.32%), phytates (0.29 – 0.43%), tannin (0.03 – 0.08%) and saponnin (0.36 – 0.49%). Methane (ml/200mg DM) production indicated T3 (50% roasted Delonix regia seed and 50% Pennisetum purpureum) was highest. The potential gas production 'a+b' ranged from 12.33 to 28.33mL/200mg DM). The highest potential gas production 'a+b' value of 28.33mL/200mg DM was obtained in T1 compared to other dietary treatment. Dry matter digestibility (DMD) ranged between 70.23 – 91.02% while the rate of fermentation was between 0.51 and 1.18ml/hr. The rate of fermentation was directly proportional to dry matter digestibility (DMD); the soaked recorded the highest value. Processing enhanced the nutritional contents of Delonix regia seeds. The result obtained showed that there were significant differences (p<0.05) among the treatments. In conclusion, soaking the seeds of Delonix regia had beter nutritional contents and has the potential for dry season feeding.

SUMMARYThe current study was conducted to determine chemical composition, nutrient content and availability, metabolizable energy (ME) content and nutritive value of sainfoin hay for ruminants. Three ruminally cannulated Holstein cows were used forin situandin vivoexperiments, to determine rumen degradability and digestibility of sainfoin hay. Apparent total tract digestibility of nutrients was determined with feeding of sainfoin hay as the sole diet to achieve 10% more than maintenance energy requirements. Six Zandi ewes were used in the palatability experiment. Means for dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF) and condensed tannins (CTs) of sainfoin hay were: 940·4 g/kg and 93·43, 12·13, 47·87, 43·33 and 2·13 g/kg DM, respectively.In situeffective degradability of CP and DM were 0·38 and 0·54 g/g with a ruminal outflow rate of 0·05/h, respectively. OM apparent digestibility was in the range of 0·592–0·689, respectively, for Tilley & Terry and total faecal collection assays. ME content of sainfoin hay, according to different methods (gas production,in vitroandin vivodetermined digestible organic matter in dry matter (DOMD)) was in the range 6·87–10·11 MJ/kg DM. Metabolizable protein (MP) content was 483·4 g/kg CP. Sainfoin was more palatable than alfalfa for sheep. It was concluded that sainfoin has a potential use in ruminant rations, especially if environmental conditions are not suitable for alfalfa production.

AbstractThe aim of the study was to determine the effect of the method of fragmentation of hybrid rye and maize grain on digestibility parameters for ruminants. Varying degrees of fragmentation – none (whole grains; WG), crushed (CG) or ground to pass through a 4.0 (GG4.0) or 1.5 mm (GG1.5) screen – were estimated by the in sacco nylon bag technique, in vitro true digestibility (IVTD), and the in vitro gas production (GP) technique. WG, CG, GG4.0 and GG1.5 were categorized as none, slight, moderate and extensive fragmentation of the grain kernel, respectively. Three non-lactating cows fitted with ruminal and duodenal cannulas were used to determine the effective rumen degradability (ERD) and intestinal and total tract digestibility (ID and TTD, respectively) of dry matter (DM), crude protein (CP) and starch. IVTD was determined with an ANKOM DaisyII Incubator, and GP and in vitro organic matter digestibility were determined with an ANKOMRF Gas Production System. Dry matter, CP and starch of hybrid rye grain were rapidly degraded in the rumen, and this degradability as well as ID and TTD was only marginally affected by the method of kernel fragmentation; however, among the methods used, the ERD of GG4.0 rye was the lowest. On the other hand, the greater the degree of kernel fragmentation, the higher ERD, ID and TTD were obtained for the DM, CP and starch of maize grain. In summary, rye grain is more susceptible to fermentation in the rumen than maize grain, but the means of grain processing may alter the rate, extent and site of their digestion, particularly for maize grain.

Chemical composition, in vitro fermentation and in situ degradability of the native South American legumes Adesmia bicolor and A. macrostachya were studied at vegetative (VG), flowering (FW) and seeding (SD) stages, and compared with those of alfalfa at 10% flowering (AL) in two separate studies. In A. bicolor, crude protein (CP) content was highest for FW, and FW and SD showed higher values than did AL (P < 0.05). At all stages, A. bicolor showed a lower content of neutral detergent fibre and acid detergent fibre than did AL (P < 0.05). The maximum gas production (Coefficient b) was highest for FW, and no differences were recorded between SD and AL, the lowest value being for VG (P < 0.05). The effective dry matter degradability was higher for FW and VG than for SD and AL (P < 0.05), whereas effective CP degradability tended (P = 0.077) to be higher for FW than for the other stages of A. bicolor, but no differences between FW and AL were detected. A. macrostachya had lower CP content (P < 0.001), but its VG and FW stages also had lower proportions of neutral detergent fibre, acid detergent fibre and acid detergent lignin (P < 0.01) than did AL. Chemical and fermentation parameters were affected by maturity of A. macrostachya. The effective dry matter degradability was higher for VG and FW than for SD and AL (P < 0.001), but no differences were apparent on the effective CP degradability. A. bicolor showed a high nutritive value, which was even higher than that of AL, and the maturity stage of this species did not markedly affect its nutritive value, whereas the nutritive value of A. macrostachya reduced as it matured.

The study analyzed the characteristics, chemical composition, and in vitro gas production kinetics of Porphyra umbilicalis and Saccharina latissima silages. Each seaweed was ensiled in vacuum bags (three bags/silage) following a 2 × 3 factorial design, with two pre-treatments (unwilted or pre-wilted) and three silage types: unwashed seaweed ensiled without additive; seaweed washed and ensiled without additive; and seaweed washed and ensiled with 4 g of formic acid (FAC) per kg seaweed. Silages were kept for 3 months in darkness at 20 °C. Pre-wilting prevented (p < 0.001) effluent formation and reduced (p ≤ 0.038) the production of NH3-N and volatile fatty acids for both seaweeds. Both pre-wilting and washing increased (p < 0.05) the ruminal degradability of P. umbilicalis silages but not of S. latissima silages. The pH of the FAC-treated silages was below 4.0, but ranged from 4.54 to 6.23 in non FAC-treated silages. DL-lactate concentrations were low (≤23.0 g/kg dry matter) and acetate was the predominant fermentation product, indicating a non-lactic fermentation. The estimated ruminal degradability of the P. umbilicalis and S. latissima silages was as average, 59.9 and 86.1% of that for high-quality rye-grass silages, respectively, indicating a medium-low nutritional value of these seaweed silages for ruminants.

The objective this study was to evaluate the effect of maniçoba supplementation in sugar cane silage with respect to chemical-bromatological composition and the in vitro degradation kinetics of the silage. This experiment was conducted in a completely randomized design with four treatments (maniçoba levels: 0, 20, 30, and 40%) and six repetitions. Silage samples were analyzed for their chemical-bromatological composition, digestible energy, metabolizable energy, total digestible nutrients, in vitro gas production and degradability parameters. The silage with higher inclusion level had better bromatological composition (p < 0.05) than the silage without maniçoba for CP, NDF, ADF and MM (6.49, 56.64, 38.66 and 4.52% versus 2.21, 70.96, 49.95 and 2.78%). Higher ME content (2.35 MJ kg-1 MS versus 1.85 MJ kg-1 MS), DE (2.87 Mcal kg-1 MS versus 2.25 Mcal kg-1 MS) and TDN (65.16% versus 51.11%), respectively. The highest values for gas production were also observed in silage with added maniçoba due to higher NFC content (34.87%). With an increase in the proportion of maniçoba, there was an increase in the soluble a fraction, b fraction, and thus a higher effective degradability of dry matter (46.56%). The addition of maniçoba improves the nutritive value of sugarcane silage.

SUMMARYForage sorghum (FS) (Sorghum bicolor(L.) Moench) is a key feed source for ruminants owing to its high yield and drought tolerance. The present paper assessed the agronomic characteristics, silage quality, intake and digestibility of five new Brazilian sorghum cultivars (BRS Ponta Negra variety, BRS 655 hybrid, BR 601 hybrid, BRS 506 variety and BRS 610 hybrid). Forages were grown (randomized complete block design) in a typical Brazilian north-eastern semi-arid climate, irrigated with 267 mm water, harvested as plants reached the soft dough stage of grain maturity and ensiled under laboratory and farm conditions. Apparent digestibility of the silages was determined using 25 Santa Inês lambs. BRS 506 outperformed the other cultivars in dry matter (DM) and digestible DM yields/ha. BRS 506 exhibited the lowest neutral detergent fibre (NDF) and acid detergent fibre (ADF) contents and the highestin vitrodry matter digestibility (IVDMD) of the cultivars examined. BRS 655 produced the lowest level of lactic acid and the highest pH and ammonia-N concentration. There was no difference in intake or digestibility of DM among cultivars. Silages produced from BRS Ponta Negra resulted in higher crude protein (CP) intake than BRS 655. Silages made from BRS 506 and BRS Ponta Negra resulted in a greater digestibility of CP than those produced from BRS 655. Intake of NDF in silages generated from BRS Ponta Negra and BRS 610 was higher than that found in other cultivars. Although an average Brazilian North-eastern FS exhibited similar characteristics to other cultivars grown in dry regions around the world, the results indicated that BRS 506 had a yield advantage and higher nutritive value under Brazilian semi-arid conditions as compared to the other cultivars examined.

Abstract This study aimed at elucidating the use of three different rumen fluid (RF) of indigenous cattle breeds i.e. Bali, Madura and Crossbred Ongole immediately after slaughtered at abattoir to evaluate the nutritive value of elephant grass( EG) -concentrate mixture using a standard in vitro gas production (IVGP) technique. Approximately 500 mg feed dry matter/syringe was added with 50 ml RF-buffer solution and incubated in a 39 0C water bath for 48 hours where gas production was observed at time intervals. Following termination of incubation the content was transferred into tare glass crucible to measure rumen dry matter (RDMD) and organic matter (ROMD) digestibility. The results showed that there was no significant different (P>0.05) in gas production parameters. In contrast, RDMD and ROMD differed significantly (P<0.01) among cattle breeds. RF from OCB resulted in the highest IVGP, RDMD and ROMD as compared with other RF sources. In conclusion, the use of RF from abattoir for IVGP measurement can be warranted using the same source of RF. The highest values resulted from OCB suggests that the abundance and variation in rumen microbiota may exist among cattle breeds.

Combining corn with legumes for silage is a feasible strategy to improve crude protein concentration in corn silage. This study was conducted to determine the fermentation characteristics and overall nutritive value of ensiled corn (Zea mays L.), vine peas (Pisum sativum L.), and mixtures of the two crops at three different ratios. The two crops were ensiled in corn/pea mixtures containing 0, 33, 50, 67, and 100% corn in vacuumed plastic bags for 60 days at room temperature. The addition of peas to corn crude protein and dry matter concentrations in the ensiled forages had a negligible influence on neutral detergent fibre concentration compared with corn silage. Corn silage had a greater (P < 0.05) lactic acid concentration than vine peas silage and the mixtures. There were no differences (P > 0.05) in in vitro dry matter and neutral detergent fibre digestibility among the silages made from the vine peas, corn, and mixtures. Improved fermentation characteristics were obtained in vine peas and corn mixture silage at a ratio of 33 : 67 compared with the other mixtures and vine peas silage. Results generated from this study suggest that combining vine peas with corn for silage could provide livestock with not only a high energy concentration feed, but a high concentration of crude protein as well.
