Abstract
A novel nutrient formulation containing tellurium for use in poultry, and a method of feeding it which improves subsequent livability, cumulative feed efficacy or weight gain is disclosed.
Claims18
A feed composition for enhancing the weight gain or feed conversion efficacy of poultry which comprises an effective amount of a source of tellurium.
A feed composition for enhancing the weight gain or feed conversion efficacy of poultry, comprising an effective amount of a compound of the formula:
- 10
- or the complex of TeO2.HOCH2CH2.NH4Cl;
- or
- 11
- or
- TeO2 or complexes of TeO2 (C)

- PhTeCl3 (D)
- or
- (C6H5)4P+(TeCl3(O2C2H4))—
- or
- TeX4,
- wherein t is 1 or 0;
- u is 1 or 0;
- v is 1 or 0;
- R, R1, R2, R3, R4, R5, R6, R7, R8, and R9 are the same or different and are independently selected from the group consisting of hydrogen, hydroxyalkyl of 1 to 5 carbons, hydroxy, alkyl of 1 to 5 carbon atoms, halogen, haloalkyl of 1 to 5 carbon atoms, carboxy, alkylcarbonylalkyl of 2 to 10 carbons, alkanoyloxy of 1 to 5 carbon atoms, carboxyalkyl of 1 to 5 carbons atoms, acyl, amido, cyano, amidoalkyl of 1 to 5 carbons, N-monoalkylamidoalkyl of 2 to 10 carbons, N,N-dialkylamidoalkyl of 4 to 10 carbons, cyanoalkyl of 1 to 5 carbons alkoxy of 1 to 5 carbon atoms, alkoxyalkyl of 2 to 10 carbon atoms 1 and —COR10 wherein R10 is alkyl of from 1 to 5 carbons;
- and X is halogen and complexes thereof.
A method for enhancing the weight gain in poultry by feeding a feed composition comprising, by weight of the diet,
- (a) a standard feeding diet containing about 0.0001% of a non-toxic source of selenium;
- and
- (b) about 0.0005% of a tellurium compound.
A dietary supplement for enhancing weight gain in poultry comprising
- (a) a non-toxic source of selenium;
- and
- (b) a tellurium compound.
