Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.

Ostrich hatching method
Prepare: Check whether the hatching maneuver is normal before hatching. Code plate: After the eggs in the egg storage room are taken out, they are placed at room temperature at room temperature so that the eggs can gradually increase the egg temperature, and then the eggs are discharged on the hatchery tray. This is called a “code plateâ€. When discharging, because the large and small ends of the ostrich eggs are unclear, it is necessary to perform egg-laying when arranging the eggs, and put the large end of the eggs, that is, the air chamber end up. Disinfection: After the code plate, the hatching plate is moved into the incubator and fumigated together with the incubator. After the disinfection, the waste gas is discharged, and then the start-up hatching is performed. According to the egg and the dish: hatching process according to the egg times, the first time the egg, is carried out on the 6th day of hatching, then can clearly detect the absence of refined eggs and dead eggs. Eggs were hatched on the 16th day of hatching. Dead embryo eggs were detected and arranged along the normal developing eggs and placed horizontally in the hatching dish. Place the hatched egg trays and hatch them in the hatching machine. This is called "falling dish." Hatching: Embryos were hatched into a hatcher and hatched until 6 days. Robust young ostriches began to shell. Shelling occurred on the third day and shelling was completed on the sixth day. When the small ostrich breaks the shell, it first dunks a large hole in the eggshell and takes a rest. Afterwards, the strong shell is kicked off with strong legs. However, the weak brood needs artificial feeding to break the shell. Don't forcibly strip shells during midwifery to avoid loss. Treatment of young ostriches: After the chicks are hatched, they are allowed to rest in the hatcher for 5 hours and transferred to the brooding room for rearing. China Agricultural Network Editor
