METHOD FOR IMPROVING PRODUCTIVITY IN LIVESTOCK AND/OR POULTRY AND METHOD FOR IMPROVING INTESTINAL FLORA IN LIVESTOCK AND/OR POULTRY
The present invention aims to provide means capable of improving the intestinal flora and the productivity of livestock and/or poultry, especially means for improving the weight gain, the feed conversion ratio, and the uniformity of livestock and/or poultry. The object is achieved by providing a method of improving the productivity of livestock and/or poultry, and a method of improving the intestinal flora of livestock and/or poultry, by feeding the livestock and/or poultry with a feed containing trehalose and probiotics, and providing a feed for livestock and/or poultry containing trehalose and probiotics.
1 . A method of improving productivity of livestock and/or poultry, the method comprising feeding the livestock and/or poultry with a feed containing trehalose and probiotics.
2 . The method of improving productivity of livestock and/or poultry according to claim 1 , wherein the improvement of productivity is one or more selected from body weight gain, reduction in a feed conversion ratio, and improvement of uniformity.
3 . A method of improving intestinal flora of livestock and/or poultry, the method comprising feeding the livestock and/or poultry with a feed containing trehalose and probiotics.
4 . The method according to claim 1 , wherein the livestock and/or poultry is/are a cow, pig, and/or chicken.
5 . The method according to claim 1 , wherein the probiotics comprise a bacterium belonging to the genus Bacillus.
6 . The method according to claim 5 , wherein the bacterium belonging to the genus Bacillus is Bacillus subtilis.
7 . The method according to claim 1 , wherein the feeding with the feed containing trehalose and probiotics is carried out during an early rearing period.
8 . The method according to claim 1 , wherein the feed is a feed comprising 0.05% by mass to 2% by mass trehalose per feed solid, and 3.0×10 5 to 1.0×10 9 live microbial cells per 1 g (gram) of feed solid.
9 . A feed for livestock and/or poultry, the feed comprising trehalose and probiotics.
10 . The feed for livestock and/or poultry according to claim 9 , wherein the probiotics comprise a bacterium belonging to the genus Bacillus.
11 . The feed for livestock and/or poultry according to claim 10 , wherein the bacterium belonging to the genus Bacillus is Bacillus subtilis.
12 . The feed for livestock and/or poultry according to claim 9 , comprising 0.05% by mass to 2% by mass trehalose per feed solid, and 3.0×10 5 to 1.0×10 9 live microbial cells per 1 g of feed solid.
13 . The feed for livestock and/or poultry according to claim 9 , which is a feed for an early rearing period.
