guar meal

This experiment was conducted to investigate effects of different levels of Guar meal (0, 5, and 10%) and β-mannanase enzyme (0 and 0/05 percent) on microbial flora in Ileal, immune response and some blood parameters in broiler chickens during grower and finisher stages in 2×3 factorial arrangement with a randomized complete block design. Three hundred sixty Ross 308 male broiler chicks with 6 treatments and 4 replicates, 15 chicks in each experimental unit reared for 42 days. To evaluate the bacterial population in Ileum 42 day-old birds were slaughtered by cervical dislocation and after opening abdominal cavity a portion of Ileum were investigated for bacterial population. To investigate immune response one ml of sheep red blood cells was injected intramuscular to the birds at 35 day-old and blood samples were taken from wing vein at 41 day-old. In order to determine blood parameters from each treatment 4 birds were selected and blood samples for determining some blood parameters transferred to the laboratory. The results of this experiment showed that the lowest anaerobic, E.coli population observed in birds fed 10% Guar meal with enzyme supplementation (P

This experiment was conducted to investigate effects of different levels of guar meal (0, 5, and 10 %) andHemicell enzyme (0 and 0.05 %) on performance and carcass characteristics in broiler chickens during grower and finisher periods in 2×3 factorial arrangement with a randomized complete block design. 360 Ross male broiler chicks with 6 treatments, 4 replicates and 15 chicks in each experimental unit in 4 blocks werereared for 42 days.During the experiment, feed intake, weight gain and feed conversion ratio were measured. To evaluate carcass components at 42 d, four birds from each treatment were selected and weights of carcass, thighs, breast, abdominal fat, liver, spleen and pancreas were determined as percentages. Results of this study indicated, using of guar meal up to 5% in the diet had no significant effect on performance and carcass components, but using of guar meal up to 10 % without enzyme in the diet compared to the control were decreased feed intake (4098.21 vs. 4346.07 g), weight gain (1822.75 vs. 2092.83 g), and increased feed conversion ratio (2.26 vs. 2.08) in total period of rearing (P

The experiment was carried out in two steps for evaluate the feeding potential of guar meal on fattened Zel lambs and its comparison with other common oily meals (soybean، sunflower، cottonseed and canola). At the first step، the chemical composition of meals was evaluated. The results showed that there are significant differences between meals composition except dry matter; besides، guar meal had highest amount of protein by 51. 02%. In the second step feedlot performance of Zel lambs in a 90-days feedlot period was measured. There was no significance difference in terms of daily weight gain; however، it was numerically highest in guar meal consumed lambs (P<0. 05). Any significant difference was observed between feed consumption of guar and soybean (P<0. 05). there was no difference in Dry matter intake of lambs guar meal and soybean، In this study، food conversion ratio for lamb that consumer guar meal was better than any other group. Regarding to considerable similarity between guar and soybean meals- as a customary protein complementary of Iran- and results of this study، guar meal can be a suitable alternative for protein part of fattened lambs ration.

This experiment was carried out to evaluate the effect of different levels guar meal and β-mannanase on broilers male chicken. In this experiment، Four hundred Ross day old broiler chicks were randomly assigned to a 4×2 factorial design to feed broiler chickens diets containing guar meal at 4 level of guar meal (0، 3، 6 and 9%) with five replications of each treatment with or without β-mannanase. Ten chicks were assigned to each pen. The diets were based on maize-soybean meal were used: starter، 8-19 days; grower، 19-35 days; and finisher، 35-42 days. All starter، grower and finisher diets were formulated to have 21. 5، 20. 5 and 19% CP and 3050، 3100 and 3150 kcal/kg metabolizable energy، respectively. Average daily gain and daily feed intake were recorded over 19 and 42 days. Results indicated that addition of the guar meal to rations did not reduce body weight، feed consumption and feed conversion ratio. Enzyme supplementation did not significantly effect on body weight، feed consumption and feed conversion ratio. Relative weights of abdominal fat، thigh، gallbladder، liver and pancreas were not significantly affected by consumption of the guar meal at any level when compared with the control. Inclusion of the guar meal in the diet significantly decreased breast weight. The addition of β-mannanase to the diets significantly reduced ileal viscosity compared with the control group in 19 day. The results of this study show that replacement of guar meal up to 9% significantly with and without β-mannanase in broilers diet have no adverse effects on body weight، feed intake and feed conversion ratio، but leads to a reduction in breast weight. Guar meal can be used up to 3% of broiler diet with no adverse effect، but its high level (9%) reduced breast meat percentage.
