The present investigation was conducted to evaluate the nutrient composition of full fat/defatted rice bran. The content of crude protein, crude fiber, ash, total carbohydrates and total dietary fiber of full fat and defatted rice bran were 11, 13.80; 10.90, 13.10; 9.20, 11.60; 49.92, 61.46; 21.63, 24.50 per cent, respectively. The amount of total Ca, P, Mg, Fe and K of full fat and defatted rice bran were 69.23, 69.80; 1331, 1345; 798, 826; 32.80, 33.31 and 1435, 1456 mg per 100g, respectively. The protein digestibility of full fat rice bran (65.86%) was less as compared to that of defatted rice bran (66.56%). Defatted rice bran had 6.21 mg available iron and 17.57 mg available calcium per 100g which were significantly (P less than 0.05) higher than those of full fat rice bran. Because of removal of fat, the relative amounts of other nutrients changed proportionately in defatted rice bran.

Sweet potatoes are effortlessly grown and high yielding food crop. However, these are considered as underutilized produce with limited incorporation into food industry. Hence the objectives of this study were to determine the nutrient composition and functional properties of twelve (12) sweet potato varieties available in Sri Lanka to study the potential to be incorporated into food production. The varieties analysed were Ama, Dhawala, Wariyapola White, Wariyapola Red, Shanthi, Hordi Malee, CARI 09, CARI 273, Ranabima, Gannoruwa White, Chithra and Makandura Purple. Determination of moisture, ash, crude protein, crude fat, dietary fiber (soluble/insoluble), carbohydrates and functional properties were by standard methods. Ash, crude fat and crude protein contents comprised less than 7% (dry matter; DM) with total carbohydrate content varying between 49-80% DM in studied sweet potatoes. Total dietary fiber comprises approximately 8.5% (DM) with the highest proportion being insoluble dietary fiber. Functional properties resulted a swelling capacity of 15-27 mL with high oil absorption capacity (120-220%), emulsion activity (42-48%) and stability (above 35%), and bulking density (0.62-0.95 g/cc) with least gelation concentration of 18-30%. The results prove the ability of the studied sweet potato flours to be incorporated in composite flour mixtures and novel food products.

Sweet potatoes are one of the major tuberous roots consumed around the world. The objective of the present study was to determine the nutritional composition, glycaemic indices and glycaemic loads of selected Sri Lankan sweet potato varieties, in order to address the inadequacy of information and the controversial findings on glycaemic indices. Nutrient composition (moisture, ash, digestible carbohydrates, dietary fiber, crude protein and fat) of boiled sweet potatoes, GI and glycaemic loads (GL) of nine varieties were determined using standard methods. Digestible carbohydrate content ranged between 29-88% on dry weight. Ash, crude protein and crude fat contents of the varieties ranged between 3.1-5.0%, 3.0-5.9% and 2.6-5.3% on dry weight basis (DW) respectively. The total dietary fiber content was above 9.5% DW in the studied varieties. Moisture content of boiled sweet potato tubers were 72-81% on fresh weight basis and both the GIs (86-119) and GLs (>20) were high. However, the GL reduced to medium or low when considering an actual edible portion for all the varieties except for two varieties. Sweet potatoes are a good source of highly available carbohydrates which elicit high GIs.

Abstract The objective of this study was to evaluate the effects of different defatted rice bran (DFRB) sources and processing technologies on nutrient digestibility in different intestinal segments of pigs. Nine barrows with T-cannula in the distal ileum were randomly allotted to nine different sources in which oil was pressed extracted for seven sources and was solvent extracted for two sources. The experiment contained 6 periods of 12 d, including 8 d for diet adaptation, 2 d for fecal collection, and 2 d for digesta collection. The apparent ileal digestibility (AID) of dry matter (DM), ash, total dietary fiber (TDF), insoluble dietary fiber (IDF), neutral detergent fiber (NDF), acid detergent fiber (ADF), and hemicellulose in different sources of DFRB was quite variable. There were no differences in the AID of dietary gross energy (GE), organic matter (OM), ether extract (EE), crude protein (CP), and soluble dietary fiber (SDF) between different sources of DFRB. There were no differences in the AID of dietary EE, TDF, IDF, and hemicellulose between different processing technologies. Pressed DFRBs have greater (P &lt; 0.05) average AID of dietary GE, DM, ash, OM, CP, SDF, and NDF and lower (P &lt; 0.01) ADF compared with solvent-extracted DFRBs. The apparent total tract digestibility (ATTD) of most of the dietary nutrients, except for the ATTD of dietary EE, SDF, and hemicellulose, significantly varied in different sources of DFRB (P &lt; 0.05). In addition, pressed DFRB had greater (P &lt; 0.05) ATTD of dietary SDF, NDF, ADF, and hemicellulose compared with solvent-extracted DFRB. The apparent hindgut digestibility (AHD) of dietary DM, SDF, NDF, and ADF significantly varied (P &lt;0.05) in different sources of DFRB. Exception with DM, there are no differences in the AHD of nutrients digestibility between pressed DFRB and solvent-extracted DFRB. In conclusion, DFRB in different sources and processing technologies with different physicochemical properties had different effects on nutrient digestibility in the foregut and hindgut of pigs.

The objective of this study was to evaluate nutritional and energetic value of rice by-products, with or without phytase, using growing pigs. Thirty-six male pigs were housed in individual metabolic cages. Total collection of feces and urine was carried out in two periods of ten days: five days for adaptation and five days for collection. A randomized blocks design was used, considering the sampling period as a block, with five treatments and seven replicates. Two control diets (with and without phytase - Phy) were used in the digestibility calculations, the latter in order to evaluate the enzyme influence on energy digestibility of the tested ingredients. The control diet was replaced by 30% of one of the ingredients: defatted rice bran (DRB) with and without Phy and dephytinised defatted rice bran (DDRB). The use of Phy in the control diet did not influence DRB+Phy energy digestibility. Relative to DRB+Phy, dephytinised defatted rice bran had higher contents of ME and digestible protein but lower digestible P and Ca. Phy supplementation increased Ca and P utilization of DRB and improved energy and protein digestibility. The DRB without Phy showed the lowest digestibility coefficients for all responses. Metabolizable energy, digestible protein, phosphorus and calcium of DRB, DRB+Phy and DDRB were respectively, 2140, 2288 and 2519kcal kg-1; 79.25, 92.41 and 107.10g kg-1; 1.62, 3.41, and 2.11g kg-1 and 2.80, 3.79 and 2.90g kg-1.

The objective of this experiment was to evaluate the effect of fresh, dried or silage cassava leaf to the blood urea nitrogen (BUN) of male Etawa Crossbreed (EC) goats. Twelve EC goats (grouping based on body weight with a weight range K1: 19-20 kg; K2: 20-21 kg; K3: 21-22 kg; K4: 22 kg) were allocated in housed individually throughout 90-day trial duration (14 days for animal's adaptation to the experimental diets and 7 days of faeces collection). Experimental design was randomized complete block design consisted of 3 treatments and 4 replications: concentrate + fresh cassava leaf (P0); concentrate + dried cassava leaf (P1); and concentrate + silage cassava leaf (P2). Concentrat was given at level of 50% (3% BW) and forage was given ad libitum respectively for each treatments. Variables observed were crude fiber intake, crude fiber digestibility, crude protein digestibility and blood urea nitrogen (BUN). Data were analyzed using analysis of variance (ANOVA), if there were significant effect of treatments were continued using duncan multiple range test. The results of this experiment showed that the processing of cassava leaves increased on crude fiber intake, crude fiber and crude protein digestibibility, but did not effect on blood urea nitrogen (BUN). In conclusion, processing of cassava leaves improved the consumption, digestibility but did not effect on blood urea nitrogen (BUN) of EC goats. Keywords: Blood Urea Nitrogen, Cassava Leaf, Male Etawa Crossbreed Goat

Abstract The objectives of this study were to assess graded inclusions of sunflower protein meal (SPM; crude protein: 54%, crude fat: 11%, crude fiber: 4%) and dried yeast (DY; crude protein: 50%, crude fat: 3%, crude fiber: 2%) on nutrient digestibility, stool quality, and palatability in adult cats. Both SPM and DY were included at 5% and 10% in replacement of pea protein in a high-protein, chicken-based feline diet to maintain equal macronutrient concentrations across all test diets (formulated to 41% crude protein, 18% crude fat, 3% crude fiber). The study was approved and followed by the facility’s Institutional Animal Care and Use Committee. A standard 2-bowl palatability test over a 2-day period was executed with adult cats (n = 30 each) to determine intake ratios between test diets (5% and 10% SPM or 5% and 10% DY), and test diets vs. control. Total tract nutrient digestibility was evaluated (n = 8 per diet) with 5 days of diet acclimation followed by 5 days of total fecal collection. Stool quality was evaluated on a 1–5 scale, where 1 = hard/formed and 5 = non-formed/diarrhea. All data were analyzed by ANOVA (SAS v9.4) and T-tests post-hoc (Minitab 18). Palatability and stool quality were similar (P &gt; 0.05) between all diets. Protein digestibility was lower for DY-containing diets, compared with control (5% DY at P = 0.0083 and 10% DY at P = 0.0336), but not significantly different for SPM diets (P &gt; 0.05). However, average protein digestibility was &gt;88% across all diets. The alternative protein sources tested showed merit for inclusion to diversify ingredient sources while maintaining palatability in cat diets.
