The effects of dietary fiber level on nutrient digestibility in growing pigs

The objective of this study was to investigate the effects of total dietary fiber level on nutrient digestibility and the relationship between apparent total tract digestibility of total dietary fiber, and soluble dietary fiber, insoluble dietary fiber and available energy. Sugar beet pulp was as the only fiber source. The experiment was designed as a 6 × 6 Latin square with an adaptation period of 7 d followed by a 5-d total collection of feces and urine. Feed intake tended to decrease (P =0.10) as total dietary fiber level increased. The apparent total tract digestibility of dry matter, crude protein and gross energy decreased (P <0.01) when total dietary fiber increased but the digestibility of soluble dietary fiber and insoluble dietary fiber increased (P <0.01). The digestible energy and metabolizable energy content of diets decreased (P <0.01) as the total dietary fiber increased

Low temperature fabrication of hydrangea-like NiCo2S4 as electrode materials for high performance supercapacitors

Hydrangea-like NiCo2S4 as electrode materials for high performance supercapacitors was synthesized by using a facile low temperature (90 °C) two-step hydrothermal technique without surfactant or template. The special hydrangea-like structure and large specific surface area (74.8 m2/g) provided plenty of electro active sites which were beneficial to superior pseudocapacitive performance of NiCo2S4. The supercapacitors performance of NiCo2S4 was investigated by a three-electrode system. NiCo2S4 exhibited high specific capacitance with 1475 F g−1 at a current density of 3 A g−1, and a fairly high rate capacity with 1152 F g−1 at 20 A g−1. These results indicate that low temperature hydrothermal is a very promising method to prepare electrode materials for supercapacitors
