Disclosed are a breeding method of a female pig for propagation characterized by feeding at least one lipid selected from a fatty acid having 12 to 24 carbon atoms which has a melting point falling in a range of -60 to 40° C. and an iodine value falling in a range of 30 to 470 and which has 2 to 6 d
Disclosed are a breeding method of a female pig for propagation characterized by feeding at least one lipid selected from a fatty acid having 12 to 24 carbon atoms which has a melting point falling in a range of -60 to 40° C. and an iodine value falling in a range of 30 to 470 and which has 2 to 6 double bonds in a molecule, a triglyceride containing the above fatty acid and a metal salt of the above fatty acid, and a feed for a female pig for propagation containing the above lipid in a proportion of 0.5 to 10% by weight in terms of the fatty acid described above. According to the breeding method of a female pig for propagation of the present invention, breeding results can be elevated by further increasing a litter size, allowing the number of delactation to grow large, shortening the days of returning estrus and increasing an annual average delivery frequency.

1. A breeding method of a female pig for propagation by artificial insemination, characterized by feeding to the female pig a feed comprising at least one lipid selected from a fatty acid having 12 to 24 carbon atoms which has a melting point falling in a range of -60 to 40° C. and an iodine value f
1. A breeding method of a female pig for propagation by artificial insemination, characterized by feeding to the female pig a feed comprising at least one lipid selected from a fatty acid having 12 to 24 carbon atoms which has a melting point falling in a range of -60 to 40° C. and an iodine value falling in a range of 30 to 470 and which has 2 to 6 double bonds in a molecule, a triglyceride containing the above fatty acid and a metal salt of the above fatty acid, in a proportion of 20 to 200 g per head a day in terms of the fatty acid described above in a duration extending from 30 days before the artificial insemination up to 3 weeks after the artificial insemination. 2. The breeding method as described in claim 1, wherein said lipid includes the metal salt of the fatty acid having 12 to 24 carbon atoms which has a melting point falling in a range of -60 to 40° C. and an iodine value falling in a range of 30 to 470 and which has 2 to 6 double bonds in a molecule. 3. The method as described in claim 2, wherein the feed further comprises as a lipid, a triglyceride containing a fatty acid having 12 to 24 carbon atoms which has a melting point falling in a range of -60 to 40° C. and an iodine value falling in a range of 30 to 470 and which has 2 to 6 double bonds in a molecule. 4. The method as described in claim 1, wherein the fatty acid is at least one selected from linoleic acid, linolenic acid, bishomo-γ-linolenic acid, arachidonic acid and eicosapentaenoic acid. 5. The method as described in claim 1, wherein the metal salt of a fatty acid is at least one selected from a calcium salt and a magnesium salt of the fatty acid. 6. The method as described in claim 1, wherein the feed comprising a lipid containing at least one fatty acid selected from linoleic acid, linolenic acid, bishomo-γ-linolenic acid, arachidonic acid and eicosapentaenoic acid is fed so that the total amount of the fatty acid described above comes to 1500 to 9000 g per head in terms of the fatty acid described above in a duration extending from 30 days before artificial insemination up to 3 weeks after the artificial insemination. 7. The method as described in claim 6, wherein the feed contains at least one fatty acid selected from linoleic acid, linolenic acid, bishomo-γ-linolenic acid, arachidonic acid and eicosapentaenoic acid in a lipid in a proportion of 20 to 99% by weight. 8. The method as described in claim 2, wherein the metal salt of a fatty acid is at least one selected from a calcium salt and a magnesium salt of the fatty acid. 9. The method as described in claim 1, wherein the feed contains at least one fatty acid selected from linoleic acid, linolenic acid, bishomo-γ-linolenic acid, arachidonic acid and eicosapentaenoic acid in a lipid in a proportion of 20 to 99% by weight. 10. The method as described in claim 1, wherein said feed is fed in a proportion of 30 to 180 g per head a day in terms of the fatty acid.
