This study planned to determine the differences among nutrient composition, in vitro digestibility, energy content, digestible dry matter and organic matter yields of barley forage harvested at three different stages of maturity. Each vegetation period (heading stage, seed formation stage and mature stage) was randomly assigned to 5 replication from 1 square meter area and fifteen samples were harvested in total. DM, ADF (p<0.001), and NDF (p<0.05) contents were different in each stages of barley forage. In vitro dry matter (IVDMD), organic matter digestibility (IVOMD), metabolizable energy (ME), and net energy for lactation (NEL) values of samples were determined to be lower than the other two stages at the mature stage (p<0.05). Yield parameters of barley were significantly affected by vegetation period (p<0.001). It can be concluded that all three vegetation period had significantly higher digestibility. Digestible DM, OM and energy yields were higher when harvested at the mature stage of vegetation.

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.

The aim of this study was to determine the nutrient and energy levels of red clover and lucerne forage. Investigation of forage at different maturity stages of three growths was carried out by chemical analysis, in vitro and in vivo digestibility methods.&nbsp; Generally, maturation caused a significant increase in fibre fractions. With the increasing maturity of forage samples the in vivo, in vitro, and calculated in vivo (in vivo<sub>calcul</sub>) digestibilities of organic matter (OM) linearly decreased. The in vitro and in vivo<sub>calcul</sub> digestibilities of OM averaged 0.754 and 0.708 for red clover and 0.717 and 0.667 for lucerne, respectively. The in vivo OM digestibility averaged 0.710 for red clover and 0.666 for lucerne. Gross energy (GE), digestible energy (DE), metabolizable energy (ME), net energy for lactation (NEL), and net energy for growth (NEG) averaged 18.12, 12.41, 9.60, 5.67, 5.50 and 18.09, 11.56, 9.01, 5.26, 4.99 MJ/kg of dry matter for red clover and lucerne, respectively. The effect of a vegetative stage on energy values of both forages was diverged for various growth times. When data were pooled across the estimated season, seven cutting-specific equations for descriptions of GE, DE, ME, NEL, NEG, in vitro, and in vivo OM digestibilities were obtained for red clover and lucerne, separately. The red clover model expression gave similar prediction equations for lucerne. It was possible to predict cutting-specific equations with coefficients of determination R<sup>2</sup> &gt; 0.719 for red clover and R<sup>2</sup> &gt; 0.400 for lucerne of the variation in GE, DE, ME, NEL, and NEG. The in vitro and in vivo OM digestibility equations were predicted with R<sup>2 </sup>being 0.840 (in vitro) and 0.707 (in vivo) for red clover, and 0.979 (in vitro) and 0.937 (in vivo) for lucerne. The parameters of these specific equations were statistically preferable than the general model expression which included both forages together. &nbsp;

The agronomic performance and nutritive value of Mucuna legume (Stilozobium deeringianum (Bort) Merr.) in five stages were evaluated under climatic conditions of Peruvian central coast to estimate optimum stage of use. Five cutting ages were: 21, 42, 63, 84 and 105 days. Crop growing, forage yield, chemical composition, vitro dry matter digestibility and net energy for lactation of Mucuna were evaluated. The optimum cutting age was 84 days with 25633.3 kg. Ha-1 of fresh matter and 6422.6 kg-1 ha-1 of dry matter. In this age crude protein, neutral detergent fiber and acid detergent fiber and in vitro dry matter digestibility contents were 14.94%, 44.80%, 33.15% and 66.12 %. Net energy for lactation was 1.43 Mcal.kg-1. These results show that Mucuna was well adapted to Peruvian Central Coast with high forage yield and nutritive value.

Background. A detailed study on the feed quantity and quality is required to document the available feeds and their nutritional values. Aim. The study was aimed to investigate and document the chemical composition and in vitro dry matter digestibility of major feed resources available in Tanqua-Abergelle district of central Tigray, northern Ethiopia. Methods. Ten different feed resources were evaluated for their nutritive values. Representative feed samples were collected and prepared following appropriate procedures. The samples were subjected to analysis of chemical composition and in vitro dry matter digestibility (IVDMD) using proper scientific procedures. Results. Wide variations were observed in nutritive values of the investigated feeds. The highest crude protein (CP) was measured in Atella (15.90%) followed by green grass (13.20%), mill waste (10.90%), groundnut straw (9.18%), and cowpea straw (8.11%) in descending order. Mill waste (11.84 MJ/kg DM) and Atella (11.81 MJ/kg DM) had the highest metabolizable energy (ME) followed by green grass (9.83 MJ/kg DM), groundnut straw (9.28 MJ/kg DM), Teff straw (8.56 MJ/kg DM), and cowpea straw (8.39 MJ/kg DM) in that order. The highest NDF was recorded in groundnut null (79.80%) and the lowest NDF in mill waste (35.00%) and Atella (40.60%). The highest IVDMD was seen in mill waste (81.43%) and Atella (81.21%) and the lowest in groundnut hull (39.95%). Conclusion. The nonconventional feeds have moderate protein and reduced fiber contents, and thus, they can be utilized as supplement for poor-quality feeds. These feeds need further investigation using animals to substantiate the current study.

The aim of this study was to determine the chemical, fermentation, and microbiological properties of alfalfa silages that were augmented with lavender (Lavandula angustifolia) and to appraise their in vitro organic matter digestibility (IVOMD), metabolizable energy (ME), and net energy for lactation (NEL) contents. Lavender flowers were added to alfalfa silages at 0.5, 1.0, 1.5, and 2.0% of the weight of alfalfa. An unaugmented alfalfa silage was also evaluated. After 75 day of ensiling, pH, dry matter, NDF and ADF contents of alfalfa silages had decreased and OMD had increased with the addition of lavender. No significant differences in crude protein, ash, ether extract, lactic acid, acetic acid, propionic acid, lactic acid bacteria number, ME and NEL contents were detected. No butyric acid, Enterobacteriaceae, Listeria spp, sulphide reducing anaerobes, and yeasts were found in the alfalfa silages. Mould content decreased with the addition of lavender. Thus, the addition of lavender flowers to alfalfa silages may improve their quality. Keywords: essential oil, fermentation, nutritional value, supplement

Percent Composition

Silicon (Si) is distributed throughout plant tissues, but its role in forages has not been clarified. Although Si has been suggested as an antiquality factor which limits the digestibility of structural carbohydrates, other research indicates that its presence in plants does not affect digestibility. We employed x-ray microanalysis to evaluate Si as an antiquality factor at specific sites of two cultivars of bermuda grass (Cynodon dactvlon (L.) Pers.). “Coastal” and “Tifton-78” were chosen for this study because previous work in our lab has shown that, although these two grasses are similar ultrastructurally, they differ in in vitro dry matter digestibility and in percent composition of Si.Two millimeter leaf sections of Tifton-7 8 (Tift-7 8) and Coastal (CBG) were incubated for 72 hr in 2.5% (w/v) cellulase in 0.05 M sodium acetate buffer, pH 5.0. For controls, sections were incubated in the sodium acetate buffer or were not treated.
