        Two experiments were conducted to evaluate the relationships between nutrients degradability, kinetics of hydration, functional specific gravity (FSG) of the three types of beet pulp (BP) including fine (FBP), normal (NBP) and pelleted (PBP) BP. In experiment 1, about 3 چکیده کامل
        Two experiments were conducted to evaluate the relationships between nutrients degradability, kinetics of hydration, functional specific gravity (FSG) of the three types of beet pulp (BP) including fine (FBP), normal (NBP) and pelleted (PBP) BP. In experiment 1, about 3 g of samples was weighed in sealed nylon bags (6 cm×7.5 cm, 40±5 µm pore size), incubated in rumen of two cannulated Holstein steers at 0, 3, 6, 12, 18, 24, 36 and 48 h. The dry matter (DM) degradation was different among the treatments for soluble, slowly and potentially degradable fractions, rate of degradation, and effective degradability. In experiment 2, after ruminal incubation of two bags at 0, 0.5, 1, 1.5, 3, 6, 12, 18, 24, 36 and 48 h, the bags were removed without and with washing, the kinetic of hydration, functional specific gravity (FSG) measured with pycnometer. Hydration rate and water holding capacity (WHC) were different. Grinding and pelleting decreased hydration rate and WHC of BP, but increased initial and final FSG over incubation time. Soluble, slowly degradable, and indigestible fraction of DM explained 82.4, 94.8, 2.7, 54.2, 87.3 and 79.7%; 34.1, 50.0, 2.2, 31.4, 62.2 and 63.4%; and 89.1, 12.2, 68.0, 84.7 and 92.9% of the total variation of the fractional rate of degradation, effective degradability, hydration rate, WHC, initial and final FSG, respectively. In addition, the correlations between digestion and hydration parameters were high. As BP has lower than critical size, can easily pass from the reticulorumen orifice, therefore, its FSG is more important to control ruminal retention time and degradation. پرونده مقاله

        Beet pulp as component of cattle feed can be processed in different way. Tis study was performed to characterize the physical properties of so called fine beet pulp (FBP); normal beet pulp (NBP) and pelleted beet pulp (PBP). The following parameters were determined: bulk density, kinetics of hydration, functional specific gravity (FSG), water holding capacity (WHC), soluble dry matter and intrinsic osmotic pressure (IOP) were investigated. Furthermore particle size distribution and its geometric mean were determined according to ASAE S424.1. All three types of beet pulp had similar composition, but different acid detergent insoluble nitrogen, bulk density, WHC, hydration rate, soluble matter and IOP. PBP had the highest (0.967 g/mL) and NBP had the lowest (0.623 g/mL) bulk density. WHC was 4.318, 5.261, 4.881 (g/DM) and hydration rate 0.0527, 0.0663, 0.0657 (g/DM/Min) for FBP, NBP and PBP, respectively. Grinding and pelleting significantly decreased WHC. Initial FSG of FBP was higher than of NBP and PBP (1.416 vs. 1.371 and 1.384, respectively). FSG changed with incubation time as particle size decreased. Final FSG of all three beet pulp types were similar. FBP had the highest soluble DM (28.61 vs. 17.98 and 23.66% of initial DM in NBP and PBP, respectively). In addition, FBP had the highest soluble ash (45.18 vs. 37.79 and 39.36% of initial ash in NBP and PBP, respectively). FBP had the highest IOP and there are not significant differences between NBP and PBP. The studied physical properties were highly correlated with the chemical composition of the pulp. So was bulk density negatively correlated with the neutral detergent fiber (NDF), crude protein (CP) and non-fiber carbohydrates (NFC), hydration rate and WHC and was positively correlated with the DM, EE, FSG, soluble DM and ash, and IOP. In addition, WHC was positively correlated with dry matter (DM), NDF, NFC, CP and EE, but also negatively correlated with bulk density, FSG, soluble DM, soluble ash and IOP. FSG was highly negatively correlated with DM, NDF, CP, NFC, EE, hydration rate and WHC and positive correlated with bulk density, soluble DM, soluble ash and IOP. The physical properties of beet pulp aid in establishing the nutritive value of feedstuffs for ruminant. They physical properties of feedstuff take into account the modifying role of the reticulo-ruminal function on the speed of the character of the quantitative and qualitative biochemical degradation process. پرونده مقاله

        The main purpose of this study was to investigate the effect of different levels of fiber and fat on performance, pH, and viscosity of digesta in young broilers. A total of 420 one-day-old male chicks Ross 308 were assigned to 60 cages of seven birds each. The birds fed with 15 experimental diets produced by central composite design (CCD), containing three levels of sugar beet pulp (SBP: 0.00, 1.75, 3.50%), tallow (T: 0.00, 0.50, 1.00%) and soybean oil (SO: 0.00, 0.50, 1.00%) from 0 to 14 d. The results showed that maximum average daily body weight gain (ADG: 42.10 g/b/d) and minimum feed conversion ratio (FCR: 0.99) were observed with diet containing 0.35% SBP, 0.00% T and 0.51% SO. Maximum (4.64) and minimum (3.01) pH in gizzard were found with diets containing 0.00% SBP, 0.51% T, 0.27% SO and 1.70% SBP, 0.21% T and 0.00% SO, respectively. The highest (6.94) and lowest (5.86) pH in ileum contents were obtained with diets comprising 0.00% SBP, 1.00% T, 0.43% SO and 1.47% SBP, 0.00% T, and 0.00% SO, respectively. Maximum (3.54) and minimum (1.50) viscosity in ileal digesta were observed with diets containing 3.50% SBP, 1.00% T, and 1.00% SO and 0.00% SBP, 0.00% T and 0.53% SO, respectively. This experiment has revealed that, the CCD and response surface methodology (RSM) have the efficiency to describe the relationships between different levels of SBP, T and SO and the ability to predict the optimal point of the level of diet ingredients in order to achieve the best performance. With increasing the amount of SBP and decreasing the level of T and SO in the diets, the pH of digesta in the gizzard and ileum decreased. The ileum digesta viscosity increased with increasing SBP, T, and SO levels. پرونده مقاله

        The present study was performed to investigate the effect of partially replacing of corn by broken rice (BR) and sugar beet pulp (SBP) in the diet on growth performance and carcass traits of growing Japanese quails. A total number of 324 unsexed one week old Japanese quail chicks fed on diets replacing 0, 3, 6, 9, 12 and 15% of corn by BR and SBP mixture (1:1) to study their effect on Japanese quail performance. Results indicated that live body weight increased significantly by 4.05 and 7.63% when birds fed 9% BR and SBP at 3 and 5 weeks of age, respectively, compared to the control. Compared to the control, treatment with 9% BR and SBP improved body weight gain by 5.54, 12.31 and 9.08% during 1-3, 3-5 and 1-5 weeks of age. The best feed intake was recorded in quails fed BR and SBP at 6% substituted for corn diet, while the best feed conversion ratio was observed in quails fed BR and SBP at 15%. The relative weights of internal organs were significantly affected by the dietary treatments, but the effect on either dressing or carcass yield was not significant. The economic feasibility was higher when birds fed the highest level of BR plus SBP (15%) in the diet being 1.64 compared with the control and other treatments. In conclusion, the results of this study indicated that, taking the economic efficiency into consideration, the dietary level of 15% BR plus SBP replaced maize diet could be the best percentage till 5 weeks of age. پرونده مقاله
