Abstract
A poultry feed composition including protein, vitamins and minerals, and a source of carbohydrates from the group consisting of soybean meals and corn supplemented with an α-galactosidase-based enzyme blend that catalyzes the degradation of the galactoside. The addition of the α-galactosidase-based enzyme blend increases the ratio of gain to feed, increases the amount of white meat, increases the mass and yield of the carcass, or decreases the amount of fat deposited during growth of a chicken fed the feed composition, relative to the chicken fed on an identical feed composition absent the α-galactosidase-based enzyme blend.
Claims16
A method to increase carcass yield and decrease the deposition of fat in chicken, by feeding said chicken a chicken feed composition comprising:
- (a) protein, vitamins and minerals;
- (b) a source of carbohydrates comprising a galactoside selected from the group consisting of soybeans and corn;
- and
- (c) an α-galactosidase-based enzyme blend that catalyzes the degradation of the galactoside, where the addition of the α-galactosidase-based enzyme blend increases the carcass mass, and decreases the amount of fat deposited during growth of a chicken fed the feed composition, relative to the chicken fed on an identical feed composition absent the α-galactosidase-based enzyme blend.
A nutritive method for a poultry animal to increase carcass yield and decrease the deposition of fat in the poultry, comprising the steps of:
- (a) preparing a feed composition comprised of protein, vitamins, and minerals, and further comprising a carbohydrate source comprised of a galactoside selected from the group consisting of soybeans and corn;
- and
- (b) supplementing the feed composition with a galactosidase that catalyzes the degradation of the galactoside, where the addition of said galactosidase increases the amount of carcass mass and decreases the amount of fat deposited during growth of a poultry animal fed the feed composition relative to the poultry animal fed on an identical feed composition absent the galactosidase.
A method to increase the yield of white meat and decrease the deposition of fat in poultry, by feeding said poultry a feed composition comprising:
- (a) protein, vitamins and minerals;
- (b) a source of carbohydrates comprising a non-starch polysaccharide selected from the group consisting of soybeans and corn;
- and
- (c) an enzyme that catalyzes the degradation of the non-starch polysaceharide, where the addition of the enzyme increases the amount of carcass mass and decreases the amount of fat deposited during growth of a poultry animal fed the feed composition relative to the animal fed on an identical feed composition absent the enzyme.
A method to increase carcess yield and decrease the deposition of fat in chicken, by feeding said chicken a feed supplement for addition to a chicken feed composition including a source of carbohydrates comprising a galactoside selected from the group consisting of soybeans and corn, comprising:
- (a) an α-galactosidase that catalyzes the degradation of the galactoside, where the addition of the α-galactosidase increases the carcass mass, and decreases the amount of fat deposited during growth of a chicken fed the feed composition, relative to the chicken fed on an identical feed composition absent the α-galactosidase.
