        Piriformospora indica (P. indica) as a root growth promoting endophyte may improve corn grain production and forage quality in ruminant under semi-arid climate condition. The aim of current study was to evaluate the influence of corn seedling- P. indica endophyte inoculation on grain and forage biomass yield, nutritive value and Fourier transformed infrared spectroscopy (FTIR) of molecular structures. Corn seedlings were inoculated with P. indica and were grown under natural condition and were compared with control group (12 experimental boxes per each treatment). Half of the experimental boxes from each treatment selected to make corn silage and the other half remained for grain biomass yield. Inoculation with P. indica increased grain biomass yield (P=0.05) but had no impact on chemical composition except for total carbohydrate content which tended to be greater for P. indica-inoculated group (p &lt;0.10). Leaf to stem ratio decreased (P=0.04) and ether extract increased in silages from treated corn compared with control group (P=0.04). In situ ruminal dry matter and organic matter degradability at 24 h of ruminal incubation were greater in P. indica corn grain from inoculated samples compared with control grain samples (P=0.02). Silage from P. indica group had greater in vitro rate of gas production (p &lt;0.05) and tended to have greater volume of gas produced until 24 h of incubation (P=0.06). The FTIR ratio between amid I to amid II and amid II to lignin area tended to decrease in silages from P. indica group compared with control group samples (P=0.09). The principle component analysis differentiated the FTIR area related to carbohydrate between experimental groups. In conclusion, under semi-arid climate condition inoculation of corn seedlings with P .indica may improve the feeding value of corn seed and silage in ruminants. تفاصيل المقالة

        This study was conducted to investigate the effect of biological treatment withPleurotus floridafungi on chemical composition and rumen dry matter (DM) and organic matter (OM) degradability of wheat and barley straw. Wheat and barley straw were collected from Golestan province of Iran and after pasteurization mixed with fungi spawn (than 5% by weight). After 21 days samples were dried in oven (60 ˚C) in order to stop fungi growth. Dry matter (DM) and organic matter (OM) degradation determined using nylon bag technique with two fistulated Dalagh rams and sampleswereincubated at zero to 96 hours in rumen. Fungi cultivation significantly decreased the amount of dry matter (DM), Neutral detergent fiber (NDF) and acid detergent fiber (ADF) in wheat and barley straw (P&lt;0.01). Ash and crude protein (CP) content significantly increased with processing by fungi in treatments (P&lt;0.01). Ether extract (EE) and acid detergent lignin (ADL) content did not differ by processing with fungi. The soluble fraction (a) and potential degradability (a+b) of dry matter (DM) increased (P&lt;0.05) by processing with fungi in both straw. Theinsoluble but potentially degradable fraction (b) of dry matter (DM) degradability increased (P&lt;0.05) by processing with fungi in wheat straw, but did not change in Barley straw. The a and a + b fractions of organic matter (OM) degradability increased (P&lt;0.01) by processing in both straw. The b fraction of organic matter (OM) degradability increased (P&lt;0.01) by processing with fungi in wheat straw, but did not observed difference in Barley straw. Therefore, it has been concluded that the treating the wheat and barley straw with fungi improved the nutritive value in the present study. تفاصيل المقالة

        The aim of this study was to compare the nutritional value of sunflower meal (SFM) and soybean meal (SBM) protein by determining both its ruminal degradability and intestinal digestibility. Three non lactating Jersey cows fitted with a rumen and T-type duodenal cannulas were used to estimate rumen degradability and intestinal digestibility of SFM and SBM dry matter (DM) and crude protein (CP). Samples of SFM were collected from seven sunflower processing plants (SFM1 to SFM7). Six different samples of SBM were collected from three main suppliers (SBM1 to SBM6). Both protein feeds were incubated in the rumen of the cows for 0, 2, 4, 8, 16, 24 and 48 h in 6 replications. The rapidly degradable fraction of DM averaged 24.8% for SFM which was lower (P&lt;0.01) than that observed for SBM (29.2%). The effective DM degradability of SFM (56.2 %/h), at mean rumen outflow rate of 0.06/h, was lower (P&lt;0.01) compared with SBM samples (67.3 %/h). The washable fraction a of CP was higher (P&lt;0.01) for SFM samples (26.3%) in comparison to all batches of SBM (16.5%). The effective degradability of SFM CP (67.7 %/h) at rumen passage rate of 0.06/h was higher (P&lt;0.01) than in SBM (63.0 %/h). The DM intestinal digestibility of SFM samples (42.6%) measured by the mobile bag technique was lower (P&lt;0.01) compared to SBM samples (71.9%). The intestinal digestibility of SFM CP (89.9%) was also lower (P&lt;0.01) than in SBM (94.6%). Results of this study indicate that SBM samples were more resistant to ruminal degradation than SFM. The data suggest that changing the toasting parameters can decrease degradability of SFM to improve protein quality. تفاصيل المقالة

        This research was conducted to investigate the the effect of sodium hydroxide (NaOH, 50 g/kg DM), calcium oxide (CaO, 160 g/kg DM), hydrobromic acid (HBr, 60 mL/kg DM) and hydrogen peroxide (H2O2, 57 mL/kg DM) processings on the nutritive value of chickpea (Cicer arieti أکثر
        This research was conducted to investigate the the effect of sodium hydroxide (NaOH, 50 g/kg DM), calcium oxide (CaO, 160 g/kg DM), hydrobromic acid (HBr, 60 mL/kg DM) and hydrogen peroxide (H2O2, 57 mL/kg DM) processings on the nutritive value of chickpea (Cicer arietinum) residues. The chemical composition of the samples was determined using the standard methods. Degradability trial was done using nylon bag technique. In vitro digestibility of the samples was determined by the batch culture procedure. X-ray diffraction method (XRD) was used to determine the crystallininty degree of the samples. Treatments of NaOH, CaO and H2O2 increased the ash content (P&lt;0.0001). The ether extract (EE) was reduced by the NaOH and H2O2 treatments (P=0.0006). Except CaO, the other treatments reduced (P&lt;0.0001) the neutral detergent fiber (NDF). Processing with HBr increased (P=0.0014) total digestible nutrients (TDN), net energy for lactation (NEl), and net energy for gain (NEg). CaO, HBr, and H2O2 treatments increased the effective ruminal degradability (ERD) of dry matter at ruminal outflow rates of 0.02, 0.05 and 0.08 h-1 (P=0.0074, P&lt;0.0001). Except CaO (P&lt;0.0001), the other treatments had no positive effect on the samples in vitro digestibility. The treatments increased the efficiency of microbial biomass at the end of 24 h incubation (P&lt;0.0001). Chemicals reduced the crystallinity degree of chickpea residues compared to the control. The least crystallinity percentage was observed in CaO treated samples. Totally, based on the in vitro and in situ results, treatments, especially HBr, had a positive effect on nutritional value of chickpea residues. However, these results must be confirmed or invalidated by in vivo tests. تفاصيل المقالة

        Plants growable in rangelands play an important role in the feeding of ruminants; hence, the nutritive value of four plants (Falcaria vulgaris, Malva neglecta, Chenopodium album, and Polygonum aviculare) was determined by different laboratory methods. The plant samples were randomly collected in vegetative phase from different rangelands of Torbat-e Jam, Iran in spring 2018. The range of dry matter (125 to 184 g/kg), neutral detergent fiber (252 to 358 g/kgDM), acid detergent fiber (155 to 258 g/kgDM), crude protein (172 to 275 g/kgDM), ether extract (9 to 41 g/kgDM), crude fiber (135 to 185 g/kgDM), ash (140 to 252 g/kgDM), acid detergent lignin (41 to 123 g/kgDM), nitrogen-free extract (300 to 496 g/kgDM), and non-fiber carbohydrates (183 to 356 g/kgDM) were different between the studied plants. The mineral composition was also different between treatments and they were containing reasonable minerals as compared to some other plants commonly used as forage feed. The highest in vitro organic matter digestibility (OMD: 876 g/kgDM) and in vitro dry matter digestibility (DMD: 828 g/kgDM) were observed in Polygonum aviculare. The other fermentation parameters (NH3-N, total volatile fatty acids: TVFA, and pH) were also different among the plant species when incubated in the laboratory medium. There was a strong positive correlation between 24 h gas production with OMD, DMD and TVFA and negative correlation between 24 h gas production with crude protein, NH3-N and ether extract. The results showed that each of the four studied plants can be considered as a potential source of feedstuff for the alleviation of problems associated with lack of forage in Iran. According to these reported data, it seems that the nutritional value of Falcaria vulgaris and Polygonum aviculare is higher than the other two plants. تفاصيل المقالة

        The objective of the study was to evaluate the nutritional value of some native plants, collected from Algerian arid zones by in vitro gas production method. The volatile fatty acids (VFA) of samples were also determined in the culture medium. This work was carried out in 2011 and was conducted in comparison to a control substrate (oat vetch) considered as a reference plant in literature. The selected plants were collected in the arid areas of the Algerian desert. Nine forages including six dicotyledon plants (Atriplex halimus L., Artemisia campestris L., Artemisia herba-alba subsp. valentina, Astragalus gombiformis Pomel, Spartidium saharae (Coss. & Dur.) and Retama raetam Forssk., and three monocotyledon plants (Stipagrostis pungens (Desf.), Lygeum spartum L.and Stipa tenacissima L.) were selected. A. campestris, A. gombiformis and A. herba-alba recorded the highest values of gas production. The total VFA production of the different substrates is significantly different between them (p&lt;0.0001). A. gombiformis had the highest total VFA (34.7 mmol/L) followed by A. campestris (32.8 mmol/L), while the lowest total production of VFA was observed in S. tenacissima (17.3 mmol/L). Generally, the plant studied can be classified in two groups, one group with poor-quality grasses (L. spartum. and S. tenacissima) and other with higher digestibility (A. gombiformis and Artemisia spp.). In conclusion, dicot species are therefore recommended for feeding ruminants. تفاصيل المقالة
