324 High-Protein Distillers Dried Grains with Solubles Produced Using a Novel Front-End-Back-End Fractionation Technology Has Greater Nutritional Value Than Conventional Distillers Dried Grains with Solubles When Fed to Growing Pigs.

Abstract Concentrations of digestible and metabolizable energy and digestibility of phosphorus in a new source of high-protein distillers dried grains with solubles fed to growing pigs Minoy Cristobal, Su A Lee, and Hans H. Stein The objective of this research was to test the hypothesis that concentrations of DE and ME and standardized total tract digestibility (STTD) of P in high-protein distillers dried grains with solubles (HP-DDGS) are greater than in conventional distillers dried grains with solubles (DDGS-CV). In Exp. 1, twenty-four growing barrows (initial BW: 32.7 ± 3.1 kg) were fed a corn diet or 2 diets containing corn and HP-DDGS or corn and DDGS-CV. The statistical model included ingredient as a fixed effects and replicate as the random effect and the pig was the experimental unit. Results from Exp. 1 indicated that the concentrations of DE and ME of HP-DDGS were greater (P < 0.05) compared with DDGS-CV (Table 1). In Exp. 2, thirty-two growing barrows (initial BW: 20.2 ± 0.9 kg) were allotted to 4 diets with 8 pigs per diet. The DDGS-CV or HP-DDGS were included in a diet without microbial phytase and in a diet with microbial phytase (500 units/kg diet). The statistical model included ingredient, phytase, and the interaction as fixed effects and replicate as the random effect. Results from Exp. 2 indicated that inclusion of phytase in the diet containing HP-DDGS increased (P < 0.05) the STTD of P, but addition of phytase to the DDGS-CV diet did not increase STTD of P (interaction, P < 0.001; Table 2). The value for the STTD of P was greater (P < 0.05) in DDGS-CV compared with HP-DDGS. In conclusion, HP-DDGS has greater concentrations of DE and ME, but less STTD of P compared with DDGS-CV.

Abstract The objective of this experiment was to test if standardized ileal digestibility (SID) of AA in a new source of high-protein distillers dried grains with solubles (HP-DDGS) is greater than in conventional distillers dried grains with solubles (DDGS-CV). Nine barrows (initial BW: 67.2 ± 6.4 kg) with a T-cannula in the distal ileum were allotted to a triplicate 3 × 3 Latin Square design with 3 diets and 3 periods. Two diets included HP-DDGS or DDGS-CV as the sole source of CP and AA. A nitrogen-free diet was used to determine basal endogenous losses of CP and AA. The statistical model included ingredient as fixed effect and square, period, and animal as random effects. Results indicated that that HP-DDGS contained more CP and AA compared with DDGS-CV (Table 1). The SID of all AA in HP-DDGS were greater (P < 0.001) compared with DDGS-CV with the exception that the SID of Pro was not different between the 2 sources of DDGS. The greater concentrations of AA and values for SID of AA in HP-DDGS indicate that this new DDGS source has a very high quality and may be a great source of digestible AA in diets fed to pigs.

Nutritionally balanced ingredient blends for catla (Catla catla), belonging to the family Cyprinidae, were extruded using single screw extruder. The extrusion was carried out at five levels of soy white flakes content (21%, 29%, 40%, 52%, and 59% db), five levels of moisture content (15, 19, 25, 31, and 35% db) and five levels of barrel temperature (100, 110, 125, 140, and 150 ºC) using three different die nozzles (having L/D ratios 3.33, 5.83, and 7.25). Blends with net protein content of 32.5% contains soy white flakes, along with high protein distillers dried grains (HP-DDG), corn flour, corn gluten meal, fish meal, vitamin, and mineral mix. A central composite rotatable design (CCRD) and response surface methodology (RSM) was used to investigate the significance of independent and interaction effects of the extrusion process variables on the extrudates physical properties namely pellet durability index, bulk density, water absorption and solubility indices and expansion ratio. Quadratic polynomial regression equations were developed to correlate the product responses and process variables as well as to obtain the response surfaces plots. The independent variables had significant (P < 0.05) effects on physical properties of extrudates: (i) higher soy white flakes content increased the pellet durability index and water absorption index, but decreased the water solubility index, (ii) higher temperature decreased pellet durability index, bulk density and water solubility index, (iii) increased L/D ratio from 3.33 to 7.25 increased the pellet durability index, expansion ratio but decreased the bulk density of the extrudates.

Growth And Reproduction

Previous studies (e.g. Cia et al. 1998) have shown that modification of body composition of the prepubertal gilt has effects on responsiveness of gilts to exogenous gonadotrophin. Growing pigs are able to select a diet from different foods differing in protein:energy ratio (Dalby 1998); however there is little evidence of what effect the conflicting nutritional demands of growth and reproduction have on diet selection. The objectives of the experiment were to quantify the effects of choice feeding on responsiveness of gilts to exogenous gonadotrophin (Cia et al. 1998) and to investigate the effect of protein source on diet selection as Jones et al.(2000) have observed selection by breeding gilts against a high protein diet containing fishmeal.
