        This research was performed to compare electron beam (EB) and gamma ray (GR) treatments at doses of 25, 50 and 75 kilo Gray (kGy) on ruminal degradation kinetics and in vitro digestibility of sunflower meal (SFM). Ionizing radiations of EB and GR had significant effects چکیده کامل
        This research was performed to compare electron beam (EB) and gamma ray (GR) treatments at doses of 25, 50 and 75 kilo Gray (kGy) on ruminal degradation kinetics and in vitro digestibility of sunflower meal (SFM). Ionizing radiations of EB and GR had significant effects )P<0.05( on dry matter (DM), crude protein (CP) and amino acid (AA) degradability parameters of SFM. Effective ruminal degradability (ERD) of DM was lower in EB and GR irradiated SFM than in unirradiated SFM) P<0.05(. GR treatment at a dose of 75 kGy decreased ERD of CP compared to control )P<0.05(. ERD of CP was not affected by EB )P>0.05(. Irradiation processing caused a decrease in AA degradation after 16 h of ruminal incubation significantly )P<0.05(. GR irradiation was more effective than EB irradiation in lessening the ruminal degradability of AA.In vitro CP digestibility of EB and GR irradiated SFM was improved )P<0.05(. This study, based on in situ andin vitro measures, showed that EB and GR processing can be used as an efficient method in improving nutritional value of SFM. پرونده مقاله

        2 - <i>In situ</i> Evaluation of Ruminal Degradability and Intestinal Digestibility of Sunflower Meal Compared to Soybean Meal

        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. پرونده مقاله

        The aim of the present study was to evaluate the influence of roasted soybean and sunflower meal on the consumption and growth performance of lambs from the Blackhead Pleven Breed. The results indicated that the addition of roasted soybean caused the lambs to grow significantly faster than those fed sunflower meal (P&lt;0.01). Adding roasted soybean to the feed caused lambs to intake significantly less maize and roughage, while intake more protein feed at the same time. Combined with the significantly higher growth rate (P&lt;0.01), lambs receiving roasted soybean exhibited lower expenditure of dry matter, concentrated feed and raw protein for 1 kg of growth, compared to lambs who were fed with sunflower meal (P&lt;0.01). The intake amount of dry matter had a significant effect on the average daily gain in lambs consuming roasted soybean, with a high correlation coefficient (r=0.645). In both groups of lambs, raw protein and FUG feed units for growth intakes significantly affected the animals&rsquo; growth performance. پرونده مقاله

        This study was conducted to evaluate the effect of different levels of sunflower meal (SFM) and niacin on laying hens performances, biochemical parameters, antioxidant status, and egg yolk cholesterol concentration. A total of 960, White Leghorn (Hy-Line W-36) commercial layers were randomly assigned to 12 groupsof 8 replicates with 10 hens each. Hens were allocated to diets 1 through 12 in a 3 &times; 4 factorial design and the dietary treatments included 3 levels of SFM (0, 10 and 15%) and 4 levels of niacin (0, 175, 225 and 275 mg/kg) fed to the birds for 10 weeks. Feed consumption was not affected (P&gt;0.05) by niacin, SFM and SFM &times; niacin interaction. Dietary supplementation of 15% of SFM significantly (P&lt;0.05) reduced egg weight, egg production and consequently egg mass. However, dietary addition of 275 mg of niacin/kg of diet increased (P&lt;0.05) egg production and egg mass. Egg weight was not affected (P&gt;0.05) by dietary addition of niacin. Feed conversion ratio was affected (P&lt;0.05) by dietary addition of SFM and was not affected (P&gt;0.05) by dietary incorporation of niacin and the SFM &times; niacin interaction. In fact, dietary supplementation of 15% of SFM significantly increased (P&lt;0.05) FCR from 2.12 to 2.14. With the exception of shell thickness, all other parameters were not affected (P&gt;0.05) by dietary addition of niacin. Dietary supplementation of 15% of SFM reduced (P&lt;0.05) egg shell thickness from 0.29 to 0.28. However, only egg shell strength was affected (P&lt;0.05) by dietary incorporation 275 mg of niacin/ kg of diet. Egg yolk cholesterol content was affected (P&lt;0.05) by dietary addition of SFM and niacin. Our data also showed that serum concentration of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and triglycerides (TG) levels were not affected (P&gt;0.05) by dietary incorporation of SFM, niacin, and their interaction. By contrast serum concentration of total cholesterol (TC) were affected (P&lt;0.05) by dietary addition of SFM, niacin and their interaction. There were no effects (P&gt;0.05) of the experimental diets on total antioxidant capacity (T-AOC), total superoxide dismutase (TSOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) serum concentration. پرونده مقاله
