Embodiment 1

[0032] Example 1 Oleic acid promotes the proliferation of porcine primary mammary epithelial cells

[0033] 1. In order to study the effect of oleic acid (OA) on the proliferation of mammary gland epithelial cells, the experiment first took pig primary mammary gland epithelial cells as the research object:

[0034] (1) Porcine primary mammary epithelial cells were cultured in DMEM-F12 medium containing 10% fetal bovine serum;

[0035] (2) Porcine primary mammary epithelial cells were treated with oleic acid (5, 10, 20, 50, 100 μM); the solvent of different concentrations of oleic acid was absolute ethanol.

[0036] (3) Cells were collected, and the cell proliferation phenotype was detected by MTT.

[0037] 2. The results are attached figure 1 shown. The results showed that 5-100 μM oleic acid could significantly ( P <0.05) to promote the proliferation of porcine mammary epithelial cells.

Embodiment 2

[0038] Example 2 Oleic acid promotes the proliferation of mouse mammary epithelial cells

[0039] 1. In order to further study the effect of oleic acid (OA) on the proliferation of mammary epithelial cells, mammary epithelial cells HC11 were used as the research object, and HC11 cells were cultured in RPMI-1640 medium containing 10% fetal bovine serum. The above HC11 cells were treated with different concentrations of oleic acid (12.5, 25, 50, 100, 200 μM).

[0040] (1) The effect of oleic acid on the proliferation of mammary epithelial cells was determined by MTT detection method.

[0041] The results are attached figure 2 As shown in A. The results showed that oleic acid promoted the proliferation of HC11 cells in a dose-dependent manner, and the effect of promoting cell proliferation was the best at 100 μM and 200 μM.

[0042] (2) HC11 cells were treated with 100 μM oleic acid for 4 days, and the proportion of HC11 cells in S phase was detected by EdU.

[0043] The res...

Embodiment 3

[0049] Example 3 The effect of adding 2% oleic acid on the mammary gland development of puberty mice in the diet

[0050] 1. Experimental method

[0051] (1) Animal feeding conditions: 1 animal / box, single-breeding; feeding temperature and humidity: 20-26°C, 40-70%; 12 h: 12 h day and night intermittent lighting; the conditions of the breeding room are always kept stable to ensure the experiment reliability of the results. Free access to food and water, feed and drinking water were provided by the Guangdong Provincial Medical Experimental Animal Center; Quarantine: The purchased SPF grade C57BL / 6J mice were pre-fed for 7 days. Animals were checked once a day during this period.

[0052] (2) Animal grouping and treatment: 4-week-old mice were randomly divided into normal control group and oleic acid group, 10 in each group, totally 2 groups. Mice in the normal control group were fed normal diets, mice in the oleic acid group were fed normal diets supplemented with 2% oleic a...

Abstract

The invention discloses application of oleic acid in animal mammary gland development promotion and provides new application of the oleic acid. Cell experiments and animal experiments prove that the oleic acid can effectively promote the proliferation of pig primary mammary gland epithelial cells and mouse mammary gland epithelial cells HC11 and can increase the number of in-vivo mouse mammary gland duct branches and TEB to promote animal mammary gland development. The application has the advantages that the oleic acid is rich in source, free of substances harmful to animals and human being, safe and easy to obtain; in addition, the adding amount of the oleic acid in the application is low, and the oleic acid serving as the nutrition regulation substance can be directly added into animal feed, food or drugs and is safe, effective, free of toxic and side effects and promising in popularization and application prospect in the animal mammary gland development promotion.

Description

technical field [0001] The invention belongs to the technical field of animal reproduction and development, and specifically relates to a long-chain monounsaturated fatty acid-oleic acid for promoting animal mammary gland epithelial cell proliferation and mammary gland development and its application in animal mammary gland development. Background technique [0002] The mammary gland has the function of secreting milk, which can provide sufficient nutrients for the growth, development and health of offspring. During production, if the sow is too fat, fat infiltration occurs in the udder, which will affect the development of the mammary gland and adversely affect its later lactation function. At the same time, the insufficient milk production of the sow will cause the piglets to grow slowly and even cause death. Studies have found that dietary lipid supplementation in sows during lactation can improve milk fat secretion, but there are few studies on the structure and function...
