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.

Organic Matter Digestibility

This experiment was aimed to study the effect of nutmeg leaf tannin addition on in vitro nutrient digestibility. Treatments in this experiment consisted of: P0 (control without tannin), P1 (feed + 2% tannin) and P2 (feed + 4% tannin). Feed for fermentation substrate consisted of Pennisetum purpureum and soybean meal with ratio 60:40. Fermentation was carried out using Tilley and Terry two stages in vitro technique for 48 hours. Variables measured were the digestibility of dry matter, organic matter, and crude protein in the rumen as well as the total digestive tract digestibility based on in vitro technique. The data obtained were analyzed by One Way ANOVA, and followed by the Duncan Multiple Range Test (DMRT). The results showed that rumen dry matter digestibility was lower (P<0.05) in P1 and P2 (59.03±3.24 and 57.19±1.32) compared to P0 (70.77±1.05), but did not show a significant difference (P>0.05) in the total dry matter digestibility of P0, P1, and P2 (74.88±5.28, 67.70±3.21, and 64.83±4.96). Organic matter digestibility in the rumen was also lower (P<0.05) in P1 and P2 (55.55±6.29 and 55.76±6.88) compared to P0 (75.39±0.91), but did not show significant difference (P>0.05) in total organic matter digestibility from P0, P1, and P2 (64.69±6.44, 64.33±6.34, and 61.20±5.11). The digestibility of crude protein in the rumen at P1 and P2 (45.48±5.12 and 38.47±3.44) was also significantly lower (P<0.05) compared to P0 (60.93±9.72), whereas total digestibility did not show any significant difference (P>0.05). Addition of tannin leaf nutmeg 2% optimally reduced rumen dry matter and crude protein digestibility without causing excessive negative impact on results of in vitro digestibility, so it can be used as a protective agent protein feed.

Midas marrowstem kale (Brassica oleracea L.) was grown in different row width associations with United 106 corn (Zea maize L.) in two studies and ensiled in different moisture blends with corn stover in another. Highest dry matter yields were obtained where a single row of kale was grown at 30 cm to the side of a corn row. This combination also provided the lowest moisture content feed and the highest in vitro digestibility and crude protein content. Changing the corn row width had no significant effect upon yield, plant height, in vitro digestibility, kale leaf or corn ear content. Blending kale with corn stover to provide a silage of about 70% moisture increased the digestibility and protein content of the feed and provided a silage that kept well in storage.

Pistachio (pistachio vera) is from Anacardiaceae family. According to the FAO (2003) report, Iran is the largest pistachio producer in the world (more than 310,000 tons). The most three important exported pistachio nuts of Iran are Ohadi, Akbari and Kaleghuchi (Mohammadi, 2005). About 150,000 tons in DM of pistachio by-product (PB) is produced from dehulling process in Iran, annually. This by-product is mainly consisted of pistachio hulls (PH), and then peduncles, leaves and a little amount of mesocarp and kernels. In this experiment the chemical composition, Total Phenolic Content (TPC) and tannin amount of PB and PH of Ohadi, Kaleghuchi and white varieties were determined; also, In Vitro Dry Matter and Organic Matter Digestibility (IVDMD and IVOMD) were measured.

Sunflower Cake

 The objective of this study was to evaluate the effect of the inclusion of sunflower cake replacing soybean meal in beef cattle diets on the in vitro digestibility of dry matter (IVDDM), organic matter (IVDOM), crude protein (IVDCP) and the ruminal fermentation kinetics and parameters. The experiment was analyzed according to a completely randomized design. The treatments consisted of four levels of sunflower cake, 0, 200, 400, 600 g kg-1, replacing soybean meal in the concentrate of beef cattle diets. The coefficients of IVDDM, IVDOM and IVDCP presented a quadratic effect with the addition of sunflower cake. The soluble fraction (fraction B) degradation rate and total gas production decreased linearly with the inclusion of sunflower cake. Values of pH in ruminal fluid were higher for levels 0, 200 and 600 g kg-1 sunflower cake. Sunflower cake can replace soybean meal by up to 280 g kg-1 in the concentrate of beef cattle diets, improving the in vitro digestibility of dry matter organic, matter and crude protein. Levels above 400 g kg-1 reduce ruminal digestion rate, digestibility and release of final fermentation products.

The objective of the study was to identify the effect of Trichoderma viride andSaccharomyces cerevisiae inoculant on chemical compositions, digestibility, and theobromineconcentration of fermented cocoa pod. This experiment consisted of four treatments,namely cocoa pods without fermentation as control (R0); fermentation of cocoa pods withinoculant T. viride (R1); fermentation of cocoa pods with inoculant S. cerevisiae (R2); andfermentation of cocoa pods with inoculant T. viride and S. cerevisiae mixed culture (R3).Each treatment had 3 replicates, and then was fermented for 10 days. Variables observedwere the chemical compositions i.e dry matter (DM), organic matter (OM), crude protein(CP), ether extract (EE), crude fiber (CF), nitrogen free extract (NFE), fiber fraction (Neutraldetergent fiber and acid detergent fiber), in vitro digestibility, and theobromine concentration.Data were analysed by one-way analysis of variance and followed by Duncan’s new multiplerange test (DMRT), if there were any significant difference. Results showed the inoculumaffected (P<0.05) the chemical composition, fiber fraction and in vitro digestibility. However,theobromine was not detected on cocoa pod without fermentation and fermentation.Compared to group R0, inoculation with T. viride and S. cerevisiae mixed culture (P<0.05)resulted in higher DM concentration (92.78% vs 89.72% respectively), higher CP (7.43% vs5.63% respectively), higher NDF (79.41% vs 61.18% respectively), higher ADF (73.04%vs 47.94% respectively), but was not significantly different on DM and OM digestibility(21.22% vs 22.24%, and 22.67% vs 24.31% respectively) than cocoa pod without fermentation.It is concluded that inoculant T. viride and S. cerevisiae mixed culture increased CPconcentration, but had no effect on in vitro digestibility.

Fluazifop-P, applied in the spring or fall and pronamide, applied in the fall only, reduced quackgrass infestation in established alfalfa and increased the dry matter yield of alfalfa. Herbicides did not improve alfalfa in vitro digestibility or crude protein content. Average residues of fluazifop-P in alfalfa treated with rates of 0.25 or 0.5 kg ai ha–1, were 0.1 mg kg–1when harvested 280 d after application, and 0.06 mg kg–1when harvested 295 d after application. Average residues in alfalfa harvested 41 and 55 d after application were 0.13 mg kg–1and 0.1 mg kg–1, respectively, with a 0.25 kg ha–1treatment and 0.19 mg kg–1and 0.05 mg kg–1, respectively, with a 0.5 kg ha–1treatment.

Agroindustrial co-products are a viable alternative for use in animal nutrition. Tests were conducted using eight different types of co-products and feed to evaluate the chemical composition, in vitro digestibility of dry matter, crude protein and neutral detergent fiber, and gas production by them. The co-products tested were: coffee hulls; pelleted citrus pulp; grape residue; soybean hulls; cottonseed; cassava foliage; and foods usually supplied to ruminants: corn silage and ground corn concentrate. Data of in vitro digestibility of dry matter, crude protein and neutral detergent fiber were tested by analysis of variance using the least square method; the results of gas production were interpreted by a non-linear regression by the Gauss-Newton method; and the effects of treatments were evaluated by the Tukey’s test. The coefficients of in vitro digestibility of dry matter, crude protein and neutral detergent fiber of co-products were different. Gas production was also different between co-products and feeds evaluated for the volume of gas produced from the fast and slow degradation fractions, degradation rate, bacterial colonization time, and the total volume of gas produced. The evaluated co-products exhibited greater in vitro dry matter digestibility compared to corn silage, except for cottonseed, grape residue, and cassava foliage. Co-products showed higher values of in vitro crude protein digestibility compared to corn silage, and a reduced in vitro digestibility of neutral detergent fiber, except for pelleted citrus pulp and soybean hulls. Corn silage produced larger volume of gas from the fast degradation fraction compared to the co-products and corn concentrate. Co-products analyzed had appropriate nutritional characteristics according to the techniques applied and can be included in ruminant diets.

Yield And Quality

At Kyabram, Victoria, the effects of growth stage at cutting on dry matter (DM) yield and quality of lucerne was determined during the warm season haymaking period for cultivars with contrasting winter dormancy characteristics. Growth stages at cutting were pre-flower bud, flower-bud, 10% bloom and full bloom. Cultivars were winter non-dormant CUF 101 and Pioneer Brand 572, semi-winter dormant Pioneer Brand 581 and winter dormant Pioneer Brand 545. Cultivar responses or interactions between cultivar and growth stage at cutting were not significant (P>0.05) for dry matter yield, crude protein or in vitro digestibility. Cutting of the pre-flower bud stage, compared with cutting at the 10% bloom stage, reduced DM yield by 18% (16.4 v. 13.5 t/ha), but increased crude protein content of the lucerne from 19.3 to 24%. The total protein yield per hectare was not affected by cutting stages from pre-flower bud stage to 10% bloom. Cutting lucerne at the flower bud stage rather than at 10% bloom gave increased protein content and digestibility with only a moderate yield decline. However, more frequent cutting was unsatisfactory as it decreased the density of the stand and increased the proportion of weeds and so could not be recommended.

Determination Methods

Dry matter (DM) contents of 13 silages, comprised of 5 corn, 4 legume–grass, and 4 corn–hay crop silage mixtures, were determined by (1) toluene distillation (TD), corrected for volatiles lost into the aqueous distillate; (2) TD, uncorrected; (3) freeze-drying (FD); (4) oven-drying (OD) at 40 C; (5) OD at 65 C; and (6) moisture-tester at 100 C. Corrected TD showed significantly higher (P < 0.01) DM levels compared with other methods. Up to 12.8% loss of DM resulted from heat-drying, depending on the method and the sample. Dried-ground silages were analyzed for nutrient composition. No significant changes in cell-wall constituents or organic matter contents were observed. Silages that were FD were highest in cellulose content (P < 0.05), whereas both FD and OD at 40 C resulted in significant increases in gross energy (P < 0.05) and crude protein (P < 0.01) content compared with other methods. FD or OD at 40 C resulted in the highest dry matter solubility and in vitro digestibility of cellulose, dry matter, and organic matter (P < 0.05). The lowest values for these analyses were obtained with silages heat-dried at 65 and 100 C. Results of these studies suggest that corrected TD should be used for determination of silage DM content and that in vitro analyses or other biochemical determinations should be conducted on silage samples that have been freeze-dried or oven-dried at 40 C.

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.
