Enzyme product for ruminants
A method is described for improving the digestibility of a forage diet for ruminant animals. A forage, including alfalfa, Chinese wildrye, corn silage, straw silage, corn stover, ryegrass or TMR, is treated with an enzyme product having cellulase, xylanase, beta-glucanase, pectinase, mannanase and alpha-galactosidase activities.
1. A method for improving the digestibility of a forage diet for raising mile yield and fat levels in ruminant animals, comprising the steps of:
(a) selecting a forage from the group consisting of alfalfa, Chinese wildrye, corn silage, straw silage, corn stover, ryegrass and a total mixture ration;
(b) adding to the forage an enzyme product having cellulase, xylanase, beta-glucanase, pectinase, mannanase and alpha-galactosidase activities;
(c) excluding enzymes having amylase activity to reduce the risk of acidosis and increase glucose availability to the ruminant animal;
(d) directly feeding the forage diet to the ruminant animal to reduce non-starch carbohydrates in the forage; and
(e) raising milk yield and/or fat levels in the ruminant animals.
2. The method as defined in claim 1 , wherein the enzyme product is present in an amount to provide between about 200 and about 800 units per gram of activity of cellulase, between about 750 and about 3000 units per gram of activity of xylanase, between about 225 and about 890 units per gram of activity of beta-glucanase, between about 1 and about 100 units per gram of activity of pectinase, between about 50 and about 800 units per gram of activity of beta-mannanase, and between about 1 and about 100 units per gram of activity of alpha-galactosidase.
3. The method of claim 2 , wherein the enzyme product is present in an amount to provide between about 200 and about 600 units per gram of activity of cellulase, between about 750 and about 2250 units per gram of activity of xylanase, between about 225 and about 625 units per gram of activity of beta-glucanase, between about 1 and about 5 units per gram of activity of pectinase, between about 100 and about 300 units per gram of activity of beta-mannanase, and between about 1 and about 5 units per gram of activity of alpha-galactosidase.
4. The method of claim 1 , wherein the enzyme product is present in an amount to provide between about 125 grams and about 2000 grams per ton of forage.
