METHODS FOR IMPROVING FEED CONVERSION RATIO OF POULTRY AND FOR BREEDING POULTRY
The invention of this application provides a method of breeding poultry or a method of improving a feed conversion ratio (FCR), characterized by comprising feeding Bacillus coagulans at a late stage of poultry production in breeding of the poultry, and further provides a feed additive composition for use in improving poultry FCR comprising Bacillus coagulans strain CP3425 (International Accession Number NITE BP-01693) or a derivative or variant thereof.
1 . A method for breeding poultry, characterized in that the method comprises feeding Bacillus coagulans to the poultry at a late stage of poultry production.
2 . (canceled)
3 . The method of claim 1 , wherein the Bacillus coagulans is fed in an amount of at least 5.0×10 2 cfu/g of feed.
4 . The method of claim 1 , wherein the Bacillus coagulans is fed in combination with a finisher or withdrawal feed.
5 . The method of claim 1 , wherein the poultry is for meat food.
6 . The method of claim 1 , wherein the Bacillus coagulans is fed in combination with another probiotic.
7 . The method of claim 6 , wherein the probiotic is Bacillus subtilis.
8 . The method of claim 7 , wherein the Bacillus subtilis is Bacillus subtilis strain C-3102 (International Accession Number FERM BP-1096), or a derivative or variant thereof.
9 . The method of claim 7 , wherein the Bacillus subtilis or the Bacillus subtilis strain C-3102 or derivative or variant thereof is continuously fed from before the late stage of poultry production.
10 . The method of claim 7 , wherein the Bacillus subtilis or the Bacillus subtilis strain C-3102 or derivative or variant thereof is fed from the stage of neonatal poultry.
11 . The method of claim 1 , wherein the Bacillus coagulans is Bacillus coagulans strain CP3425 (International Accession Number NITE BP-01693), or a derivative or variant thereof.
12 . The method of claim 1 , wherein the Bacillus coagulans has an ability to improve FCR by at least 1-10% when compared with control that the Bacillus coagulans is not fed to.
13 . A feed additive composition for improving a feed conversion ratio (FCR) of poultry, comprising Bacillus coagulans strain CP3425 (International Accession Number NITE BP-01693), or a derivative or variant thereof.
14 . The feed additive composition of claim 13 , further comprising Bacillus subtilis.
15 . The feed additive composition of claim 14 , wherein the Bacillus subtilis is Bacillus subtilis strain C-3102 (International Accession Number FERM BP-1096), or a derivative or variant thereof.
16 . (canceled)
17 . A method for improving a feed conversion ratio (FCR) of poultry, characterized in that the method comprises feeding Bacillus coagulans to the poultry at a late stage of poultry production.
18 . The method of claim 17 , wherein the Bacillus coagulans is fed in an amount of at least 5.0×10 2 cfu/g of feed.
19 . The method of claim 17 , wherein the Bacillus coagulans is fed in combination with a finisher or withdrawal feed.
20 . The method of claim 17 , wherein the poultry is for meat food.
21 . The method of claim 17 , wherein the Bacillus coagulans is fed in combination with another probiotic.
22 . The method of claim 21 , wherein the probiotic is Bacillus subtilis.
23 . The method of claim 22 , wherein the Bacillus subtilis is Bacillus subtilis strain C-3102 (International Accession Number FERM BP-1096), or a derivative or variant thereof.
24 . The method of claim 22 , wherein the Bacillus subtilis or the Bacillus subtilis strain C-3102 or derivative or variant thereof is continuously fed from before the late stage of poultry production.
25 . The method of claim 22 , wherein the Bacillus subtilis or the Bacillus subtilis strain C-3102 or derivative or variant thereof is fed from the stage of neonatal poultry.
26 . The method of claim 17 , wherein the Bacillus coagulans is Bacillus coagulans strain CP3425 (International Accession Number NITE BP-01693), or a derivative or variant thereof.
27 . The method of claim 17 , wherein the Bacillus coagulans has an ability to improve FCR by at least 1-10% when compared with control that the Bacillus coagulans is not fed to.
