Embodiment example 1

[0017] Implementation case 1 Effect of chitosan oligosaccharides on reproductive performance such as the number of corpus luteum and the number of implanted embryos in the ovary of mice

[0018] (1) Experimental animals: female and male Kunming mice, clean animals, 3-4 weeks old, 12±3g, provided by the 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 access to water. Feeding mice full-price compound feed for more than 4 weeks, the weight of mice can reach 26±3g, which can be used for mating experiments. The composition of the full-price compound feed is shown in Table 1.

[0019] (2) Experimental method: Female mice with similar body size and high energy were selected and randomly divided into two groups. The first group is the control group, fed with full-price compound feed without adding chitosan ol...

Embodiment example 2

[0059] Implementation case 2 Effect of chitosan oligosaccharides on the reproductive performance of mice in late pregnancy

[0060] (1) Experimental animals: female and male Kunming mice, clean animals, 3-4 weeks old, 12±3g, provided by the 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 access to water. Feeding mice full-price compound feed for more than 4 weeks, the weight of mice can reach 26±3g, which can be used for mating experiments. The composition of the full-price compound feed is shown in Table 1.

[0061] (2) Experimental method: female mice with similar body size and high energy were selected and randomly divided into two groups. The first group is the control group, which is fed with full-price compound feed without chitosan oligosaccharide; the second group is chitosan oligosaccharide, ...

Abstract

The present invention discloses applications of chitosanoligosaccharide in improvement of animal corpus luteum number, embryo nidation ability and fetal development ability. According to the present invention, per 1kg of a feed, food or drug contains 1-800 mg of chitosanoligosaccharide; and the chitosanoligosaccharide is the functional oligosaccharide with effects of improvement of female animal gestation period embryo and fetal growth and development ability, improvement of female animal ovary corpus luteum number, embryo nidation number and live fetal number at the late gestation period, and further has characteristics of no toxic-side effect, no residue, less addition, no pollution, good repeatability, and no adverse impact on the environment.

Description

technical field [0001] The present invention relates to the application of chitosan oligosaccharide in improving the number of corpus luteum of female animals, the development ability of embryo in early pregnancy and the development ability of fetus in late pregnancy, specifically, it is a function of adding in animal feed, food or medicine to regulate animal reproductive performance A sexual oligosaccharide belongs to the technical field of agricultural biological products. Background technique [0002] The output value of animal husbandry in my country accounts for one-third of the total agricultural output value. But the development of my country's animal husbandry is not strong. Among them, my country's animal breeds mainly rely on imports, and this is still the case from the past to the present. Low reproductive performance is one of the main factors restricting the rapid development of my country's aquaculture industry. The main factors affecting reproductive perfor...
