Additive composition for ruminant feeds

Feed additive compositions for ruminants containing (A) at least one member selected from the group consisting of hydrogenated vegetable oil and hydrogenated animal oil each having a melting point of higher than 50&#xb0; C. and lower than 90&#xb0; C.; (B) not less than 0.05 wt % and not more than 6 wt % of lecithin; (C) not less than 30 wt % and less than 65 wt % of a biologically active substance; (D) not less than 0.01 wt % and less than 0.8 wt % of a natural vegetable oil; and not less than 0.1 wt % and less than 6 wt % of water exhibit high protection in the rumen and are also superior in dissolution in the lower gastrointestinal tract.

Feed additive composition for ruminants

Feed additive compositions for ruminants containing (A) at least one selected from hydrogenated vegetable oil and hydrogenated animal oil each having a melting point of higher than 50&#xb0; C. and lower than 90&#xb0; C., (B) lecithin, (C) a biologically active substance, (D) a natural vegetable oil, and water, wherein when a scattering profile is measured after maintaining at 40&#xb0; C. for 15 min, and then measured by further maintaining at 40&#xb0; C. for 30 min by a small-angle and wide-angle x-ray scattering method, a peak having the maximum peak intensity in a region where the scattering angle 2&#x3b8; is not more than 5&#xb0; has a ratio (t/s) of 0.9-1.1 wherein s is peak intensity when maintained at 40&#xb0; C. for 15 min and t is peak intensity when maintained at 40&#xb0; C. for 45 min, and a peak having the maximum peak intensity in a region where the scattering angle 2&#x3b8; is 17&#xb0;-23&#xb0; has a ratio (y/x) of 0.7-0.9 wherein x is peak intensity when maintained at 40&#xb0; C. for 15 min and y is peak intensity when maintained at 40&#xb0; C. for 45 min, have high protection in the rumen and are also superior in dissolution in the gastrointestinal tract.
