Embodiment example 1
[0029] Implementation Case 1 Effect of Functional Sugars on the First Parity of Mice
[0030] (1) Experimental animals: female and male Kunming mice, clean animals, 3-4 weeks old, 12±3g, provided by Experimental Animal Center of Dalian Medical University, approval number SCXK (Liao) 2008-0002, clean animals Raised in a room with a temperature of 20±1°C, a humidity of 40% to 50%, light for 12 hours, pellet feed, and free drinking water. After feeding the mice with full-price compound feed containing functional sugar for more than 6 weeks, the weight of the mice can reach 26±3g, which can be used for mating experiments.
[0031] (2) Experimental method: weaned female mice with similar body size and active energy were randomly divided into 3 groups. The first group is the blank control group, fed with full-price compound feed without functional sugar (see Table 1); the second group is the chitosan oligosaccharide group, fed with full-price compound feed containing 300mg / kg chito...

[0041] Implementation Case 2 Effect of Functional Sugars on the Second Parity Reproductive Performance of Mice
[0042] (1) Experimental animals: The source of mice used in this group of experiments is the same as that of the previous group of experiments. After the female and male mice were mated and gave birth in Example 1, the mice were continued to be fed with functional sugar-containing feed, and the weight of the mice reached 51.2±0.4g. The mice were raised in a clean-grade animal room at a temperature of 20±1°C, a humidity of 40% to 50%, light for 12 hours, pelleted feed, and free access to water.
[0043] (2) Experimental method: Female weanling mice with similar body size and active energy were randomly divided into 3 groups. The first group is the blank control group, fed with full-price compound feed without functional sugar; the second group is the chitosan oligosaccharide group, fed with full-price compound feed containing 300mg / kg chitosan oligosaccharide; the t...

[0054] Example 3 Effects of functional sugars on the reproductive performance of mice in late pregnancy
[0055] (1) Experimental animals: female and male Kunming mice, clean animals, 3-4 weeks old, 12±3g, provided by Experimental Animal Center of Dalian Medical University, approval number SCXK (Liao) 2008-0002, clean animals Raised in a room with a temperature of 20±1°C, a humidity of 40% to 50%, light for 12 hours, pellet feed, and free drinking water. Feed the mice diet containing functional sugar for more than 6 weeks, and the weight of the mice can reach 26±3g. The mice are mated and conceived. Calculated from the first day of conception, the mice are killed on the 19th day of conception and used for the experiment.
[0056] (2) Experimental method: weaned female mice with similar body size and active energy were randomly divided into 3 groups. The first group is the blank control group, fed with full-price compound feed without functional sugar; the second group is the ...
