Abstract
The invention provides an animal feed composition comprising microbial α-amylase. The invention further provides methods of increasing the growth (weight gain), the average daily weight gain or the efficiency of feed utilization by an animal or reducing the number of days needed to achieve a desired weight in an animal, comprising feeding to the animal an animal feed composition of the present invention.
Claims26
A method of increasing the efficiency of feed utilization for body weight gain by an animal, the method comprising feeding to said animal an animal feed composition comprising transgenic corn plant material having a recombinant a-amylase comprising an amino acid sequence having at least 95% sequence identity to the amino acid sequence of SEQ ID NO:
- 1 expressed in the endosperm of seeds or kernels of the transgenic corn plant material, wherein said transgenic corn plant material is fed to the animal in an amount effective to increase the efficiency of feed utilization by said animal as compared with a control animal not fed said transgenic corn plant material;
- wherein exogenous alpha-amylase has not been added to the animal feed composition;
- and
- wherein the transgenic corn plant material comprises from 25% to 100% by weight of the animal feed composition and increases the efficiency of feed utilization for body weight gain by the animal as compared with the control animal not fed said transgenic corn plant material.
A method of increasing the efficiency of feed utilization for body weight gain by an animal, the method comprising feeding to said animal an animal feed composition comprising transgenic corn plant material from corn event 3272, wherein transgenic corn seeds or kernels from said corn event 3272 express a recombinant α-amylase in the endosperm of the transgenic corn seeds or kernels, and wherein said transgenic corn plant material is fed to the animal in an amount effective to increase the efficiency of feed utilization by said animal as compared with a control animal not fed said transgenic corn plant material;
- wherein exogenous alpha-amylase has not been added to the animal feed composition;
- and
- wherein the transgenic corn plant material comprises from 25% to 100% by weight of the animal feed composition and increases the efficiency of feed utilization for body weight gain by the animal as compared with the control animal not fed said transgenic corn plant material nor alpha-amylase supplement.
