## 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.

## Claims

### Claim 1

A method of forming a high fat feed block, the method comprising:
pouring an exotherming admixture into a container, the exotherming admixture comprising a sugar-containing component, a blendable fat, water, a hardening agent, and high fat pellets, the exotherming admixture at an elevated temperature such that the exotherming admixture is pourable into the container,
wherein the exotherming admixture contains a total fat content of about 7 wt % to 33 wt %, and
wherein the high fat pellets comprise at least one high melting point fat having a melt temperature of greater than 60° C. (140° F.) such that the high fat pellets remain discrete in the exotherming admixture; and
allowing the exotherming admixture to harden into a feed block.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

The method of claim 1, wherein the hardening agent is selected from the group consisting of magnesium oxide, calcium oxide, calcium hydroxide, and ionic salts of magnesium or calcium.

### Claim 4 (depends on 1)

The method of claim 1, wherein the blendable fat has a melting point ranging from about 20° C. (68° F.) to about 35° C. (95° F.).

### Claim 5 (depends on 1)

The method of claim 1, wherein the high fat pellets further comprise at least one low melting point fat disposed beneath a surface of the pellets.

### Claim 6 (depends on 1)

The method of claim 1, wherein the exotherming admixture further comprises one or more viscosifiers selected from the group consisting of xanthan gum, locust bean gum, agar, carrageenan, alginic acid, sodium alginate, calcium alginate, gum Arabic, gum ghatti, gum tragacanth, karaya gum, guar gum, chicle gum, dammar gum, glucomannan, psyllium seed husks, spruce gum, tara gum, gellan gum, arrowroot, corn starch, β-glucan, cellulose, methyl cellulose, pectin, potato starch, gelatin, chondrin, press cake from Irvingia gabonensis, gum karaya, gulaman, montmorillonite clay, bentonite clay, and attapulgite clay.

### Claim 7 (depends on 1)

The method of claim 1, further comprising maintaining the exotherming admixture at a temperature of about 40° C. to about 60° C. for about 12 hours to about 24 hours after pouring the exotherming admixture into the container.

### Claim 8 (depends on 1)

The method of claim 1, wherein the exotherming admixture contains about 5 wt % to about 50 wt % of the high fat pellets.

### Claim 9 (depends on 1)

The method of claim 1, wherein the sugar-containing component is selected from the group consisting of molasses, honey, sugarcane, corn syrup, sugar beet, or fruit extracts.

### Claim 10 (depends on 1)

The method of claim 1, wherein the exotherming admixture contains about 10 wt % to about 85 wt % of the sugar-containing component.

### Claim 11 (depends on 1)

The method of claim 1, wherein the exotherming admixture contains about 1 wt % to about 15 wt % of the water.

### Claim 12 (depends on 1)

The method of claim 1, wherein the blendable fat is selected from the group consisting of yellow grease, choice white grease, vegetable oils, soybean oil, flaxseed oil, sunflower oil, cottonseed oil, hydrogenated analogs of vegetable oils, nut oils, seed oils, fish oils, beef fat, or chicken fat.

### Claim 13 (depends on 1)

The method of claim 1, wherein the exotherming admixture contains about 1 wt % to about 6 wt % of the blendable fat.

### Claim 14 (depends on 1)

The method of claim 1, wherein the exotherming admixture further comprises about 5 wt % to about 50 wt % of high-fat seeds.

### Claim 15 (depends on 14)

The method of claim 14, wherein the high-fat seeds comprise flaxseeds in whole or ground form or cottonseeds in whole form.

### Claim 16 (depends on 1)

The method of claim 1, wherein the exotherming admixture further comprises one or more of corn germ, processed soybeans, or canola.

### Claim 17 (depends on 1)

The method of claim 1, wherein the exotherming admixture further comprises calcium chloride.

### Claim 18 (depends on 1)

The method of claim 1, wherein the exotherming admixture contains about 2.5 wt % to about 4.2 wt % of calcium chloride.
