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.

Quality attributes of citrus pulp silages that were ensiled alone and combined with maize silage were determined. Fresh samples of lemon, orange and tangerine pulps, maize plants and their combinations were fermented in glass jars for 90 days at about 20 - 25 °C. Treatments included i) 100% maize silage as control (MS); ii) 100% lemon pulp silage (LPS); iii) 100% orange pulp silage (OPS); iv) 100% tangerine pulp silage (TPS); v) 50% LPS and 50% maize silage (LPS + MS); vi) 50% OPS and 50% MS; and vii) 50% TPS and 50% maize silage (TPS + MS). The pH differed among treatment groups. The highest and lowest pH values were recorded for MS group and the OPS + MS group, respectively (3.84 vs. 3.51). The highest dry matter (DM), crude fibre (CF), neutral detergent fibre (NDF), acid detergent fibre (ADF) and hemicellulose (HEM) were observed for MS (P <0.01). Citrus pulp silages alone had significantly greater total digestible nutrients (TDN), organic matter (OM) and non-fibre carbohydrate (NFC) values than MS and the combined silages (P <0.01). Maize silage had higher lactic acid (LA) (101.2 g/kg DM) and acetic acid (AA) (49.3 g/kg DM) concentrations than the citrus groups (P <0.05). In vitro gas production (TG), methane (CH4), metabolizable energy (ME) and organic matter digestibility (OMD) of the silages were similar (P >0.05). Thus, citrus pulps can be ensiled in spite of their moisture content. However, to increased DM and nutrient content, the citrus pulps should be ensiled with 50% maize.

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.

Kinetics Of

By using separated values of kinetics of in situ dry matter (DM) degradation or in vitro gas production (Menke and Steingass, 1988) of leguminosae hays, Khazaal et al, (1993) reported high correlation with intake (r= 0.88; r= 0.79) and in vivo DM digestibility (DMD) (r= 0.94; r= 0.88). The aim of the present study was to extend the range of samples used and compare the ability of the 2 stages in vitro digestibility (Tilley and Terry, 1963), the in situ DM degradation or the gas production techniques to predict daily intake (g DM/ kgW0.75) and in vivo DM digestibility (DMD) of 19 leguminous and graminaceous hays fed to sheep.Three harvesting stages (early bloom EB, mid bloom MB or in seed IS) made from lucerne (Medicago sativa), sweet clover (Melilotus segetalis), Persian clover (Trifolium resupinatum), Rye (Secale cereale), Triticale (Triticale hexaploid), oat (Avena stativa) and a pre-bloom (PB) Italian ryegrass (Lolium multiflorum ). Each hay was fed ad libitum to 4 Merino male sheep and their intake and in vivo DMD recorded. Gas production (ml/ 200 mg DM) or in situ DM degradation (g/ 100 g DM) were determined as described by Khazaal et al, (1993) after 6, 12, 24, 48, 72 or 96 h incubation. Measured gas production or DM degradation values were fitted to the equation p=a+b(l-e-ct)(McDonald, 1981) where p is gas production or DM degradation at time t and a, b and c are constants. For nylon bag the washing loss (soluble fraction) was defined as A, the insoluble but fermentable matter was defined as B=(a+b)-A, and c is the rate of fermentation or degradation (Ørskov and Ryle, 1990).

SUMMARYThe digestibility of a feed containing hull material prepared mechanically from Throws MS field bean (Viciafaba L) was determined in a 12-day balance trial with sheep. The pelleted feed contained 62 % hulls and 38 % of a concentrate mixture, and was given at a maintenance level. The mean digestibility coefficients of the feed were for dry matter, 66·3; organic matter, 68·2; nitrogen, 65·7; crude fibre, 59·4; and energy, 65·5%.The coefficients for the bean hulls themselves, estimated by assuming coefficients for the concentrates, were dry matter, 59·6; organic matter, 61·0; nitrogen, 58·2; crude fibre, 60·3; and energy, 59·9%. By assuming a value of 2·515 Mcal/kg for the metabolizable energy of the concentrates, the metabolizable energy of the bean hulls was calculated to be between 2·00 and 2·10 Mcal/kg.Digestibility coefficients for the bean hulls determined in vitro were found to agree with those determined in vivo.

Several published reports on the nutritive value of whole-crop wheat (WCW) have been based on estimations from laboratory techniques, some of which were developed for grass silage. However, there is little information on the accuracy of such estimations. Therefore the aim of this study was to evaluate the suitability of predicting the in vivo digestibility of WCW from various less animal-dependent techniques.

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;

SUMMARYA rapid method for measuring gas production during incubation of feedingstuffs with rumen liquor in vitro is described. Gas production in 24 h from 200 mg feed dry matter was well correlated with digestibility of organic matter, determined in vivo with sheep. Multiple regression analysis, when it included data from proximate analysis, resulted in an equation (R = 0·98) for prediction of metabolizable energy content, based on 30 experiments with rations varying in protein and crude fibre content, and 59 other experiments with concentrates. Energy content was in the range of 7·7–13·2 MJ ME/kg D.M. (± S.D. = 11·17 ± 1·08). The residual standard deviation of the equation was 0·25 MJ. Gas production was measured in calibrated syringes. The only chemical determinations needed are dry matter, protein and fat. Differences in activity between batches of rumen liquor are corrected by reference to gas production with standard feedingstuffs (hay meal and maize starch).

Four plots of Gliricidia and two plots of Leucuena were harvested at three monthly intervals to monitor dry matter yield, chemical composition and in vitro organic matter digestibility. The plants had been established (Gliricidia from stakes, Leucaena from seeds) and were spaced 1m apart on rows and 1m between rows. Each plot size was 6m x 6m.  There was no significant difference (P>0.05) in the dry matter yield of the two browse species. Season did not have significant (P>0.05) effect on the dry matter yield of Leucaena but had on that of Gliricidia (P<0.01). The early dry harvest produced the lowest yield for both Gliricidia and Leucaena and these were significantly lower than the yield from other harvests.  Season had significant effect (P<0.01) on the chemical composition of Leucaena except on the percent Acid Detergent Fibre (ADF) and lignin but season had no effect on the organic matter digestibilities of the two browse species: Leucaena was higher in nutritive value than Gliricidia.

The purpose of this experiment was to investigate herbage production and nutritive value of C. ternatea harvested at 60, 75 and 90 days after planting. The legume was planted in eighteen of 3 × 3 m2 plots a t 40 × 20 cm2. Forage was harvested at 60, 75 and 90 days after planting as treatmens. Variables measured included forage production, nutrient content and in vitro dry matter and organic matter digestibility. Herbage production was not significantly different (P>0.05) when harvested at different stages of growth. Leaf : stem ratio, however, declined (P<0.05) with advancing growth stage. Forage quality in terms of crude protein content was comparable (P>0.05) among different harvest time. Meanwhile the energetic value as shown by in vitro organic matter digestibility (IVOMD) was significantly higher (P<0.05) when C. ternatea was harvested 60 days compared to 75 and 90 days after planting. It can be concluded that for calf supplement, C. ternatea is preferably harvested at 60 d after planting. Key words : Clitoria ternatea, IVOMD, energy, calf supplement
