Abstract

Methods form high fat feed blocks having a total fat content of about 7 wt % to 33 wt %. The blocks are formed by blending a pourable composition having a viscosity of at least 1000 cP at 57° C. with high fat pellets having total fat content of at least 40 wt % based on pellet weight, where the pellets include at least one fat having a melt temperature of greater than 60° C. Also disclosed are feed blocks formed by the methods.

First claim

The invention claimed is:

1. A method of forming a high fat feed block, the method comprising:
blending a pourable composition having a viscosity of at least 1000 cP at 57° C., the composition comprising a sugar-containing component, a blendable fat, water, and a hardening agent, wherein the pourable composition exotherms to produce a pourable composition at an elevated temperature;
admixing high fat pellets with the pourable composition at the elevated temperature to form a pourable admixture containing about 5 wt % to about 20 wt % high fat pellets, the high fat pellets having a total fat content of at least 40 wt % based on pellet weight and comprising at least one high melting point fat, the high melting point fat having a melt temperature of greater than 60° C. (140° F.) such that high fat pellets do not melt or blend with the pourable composition and remain discrete in the pourable admixture, wherein the total fat content of the pourable admixture is about 7 wt % to 33 wt %;
pouring the pourable admixture into a container; and
allowing the pourable admixture to harden into a feed block.

2. The method of claim 1 , wherein the elevated temperature of the pourable composition is at least about 50° C. (122° F.).

3. The method of claim 2 , wherein the elevated temperature of the pourable composition is below the melt temperature of the high melting point fat.

4. The method of claim 3 wherein the elevated temperature of the pourable composition is between about 50° C. and 60° C. (122° F. and 140° F.) and the melting point of the high melting point fat is about 60° C. to 75° C. (140° F. to 167° F.).

5. The method of claim 1 wherein the blending further comprises adding one or more nitrogen sources.

6. The method of claim 1 wherein the blending further comprises adjusting the viscosity to between about 1000 cP and 6500 cP at 57° C. (135° F.).

7. The method of claim 6 wherein the adjusting is accomplished by adding between 1 wt % and 15 wt % water to the pourable composition based on the weight of the pourable admixture.

8. The method of claim 1 wherein the hardening is allowed by maintaining the pourable admixture at about 40° C. to 60° C. (104° F. to 140° F.) for about 1 to 48 hours.

9. The method of claim 1 wherein the blending comprises blending between 1 wt % and 6 wt % of a blendable fat based on the weight of the admixture and the admixing comprises admixing about 5 wt % to 20 wt % high fat pellets based on the weight of the admixture.

10. The method of claim 1 wherein the admixture further comprises a high fat containing seed.
