Abstract

An object of the present invention is to improve the milk yield and/or milk quality of a ruminant for milk production, to prevent or treat a perinatal disease of a ruminant, and to improve the reproductivity of ruminant. In order to solve the above-mentioned problem, the following is provided. An agent for improving at least one of milk yield and milk quality of a ruminant, comprising at least one of cashew nut shell liquid, heat-treated cashew nut shell liquid, anacardic acid, cardanol, and cardol. An agent for preventing or treating a perinatal disease of a ruminant, comprising at least one of cashew nut shell liquid, heat-treated cashew nut shell liquid, anacardic acid, cardanol, and cardol. An agent for improving reproductivity of a ruminant, comprising at least one of cashew nut shell liquid, heat-treated cashew nut shell liquid, anacardic acid, cardanol, and cardol.

First claim

The invention claimed is:

1. A method of improving reproductivity of a ruminant in need thereof, comprising:
feeding the ruminant in need thereof a reproductivity-improving effective amount of at least one agent selected from the group consisting of a cashew nut shell liquid, and a heat-treated cashew nut shell liquid in an amount effective to improve the reproductivity of the ruminant.

2. The method of claim 1 , wherein the agent is fed to the ruminant in an amount of 0.01 to 500 g per ruminant per day.

3. The method of claim 1 , wherein the ruminant is selected from the group consisting of a cow, a goat and a sheep.

4. The method of claim 1 , wherein the ruminant is a female Holstein cow.

5. The method of claim 1 , wherein the agent is fed to the ruminant after a calving.

6. The method of claim 5 , wherein the agent is fed to the ruminant in an amount of 1-100 g of cashew shell nut liquid per day.

7. The method of claim 6 , wherein the agent is fed to the ruminant at least 5 days after the calving.

8. The method of claim 1 , wherein improving the reproductivity of the ruminant includes at least one condition selected from the group consisting of improving the rate of estrus of the ruminant, reducing the actual days of non-pregnancy of the ruminant, increasing the pregnancy rate of the ruminant and increasing the pregnancy rate at first service of the ruminant.

9. The method of claim 1 , wherein the agent comprises a cashew nut shell liquid containing 55 to 80 mass % of anacardic acid, 5 to 20 mass % of cardanol, and 5 to 30 mass % of cardol.

10. The method of claim 1 , wherein the agent comprises a cashew nut shell liquid containing 0 to 10 mass % of anacardic acid, 55 to 80 mass % of cardanol, and 5 to 30 mass % of cardol.

11. The method of claim 1 , wherein the cashew nut shell liquid and/or the heat-treated cashew nut shell liquid is administered to the ruminant in an amount of 10 g or less per ruminant per day.

12. The method of claim 1 , comprising administering the cashew nut shell liquid and/or the heat-treated cashew nut shell liquid to the ruminant together with at least one oil absorbent selected from the group consisting of magnesium oxide, stearate, talc, zeolite, diatom earth and silica in a mass ratio of 100:20 to 100:180.

13. The method of claim 1 , wherein the ruminant is raised with a feed having a ratio by weight of a forage to a total weight of the forage and a concentrate feed of from 0.3 to 1.0.
