Patent number: 11883451Abstract: A method of feeding a non-livestock ruminant animal a feed composition including a phytogenic composition for improving performance during periods of heat stress involves determining the non-livestock ruminant animal is experiencing heat stress during a period of heat stress conditions, and feeding the heat stressed non-livestock ruminant animal the feed composition including an amount of the phytogenic composition that is effective to improve performance. A method of feeding a non-livestock ruminant animal a feed composition including a phytogenic composition for improving performance in anticipation of periods of heat stress involves determining a potential for heat stress is increased based on one or more of historical weather patterns or short-term forecasts, and feeding the non-livestock ruminant animal the feed composition including the phytogenic composition based on the determined potential for heat stress.Type: GrantFiled: February 2, 2021Date of Patent: January 30, 2024Assignee: Purina Animal Nutrition LLCInventors: James D. Caldwell, Bill L. Miller

Publication number: 20190289878Abstract: The present disclosure describes animal feed products formulated to improve animal performance, and methods of feeding such products to the animals. Feeding methods involve providing young livestock animals with a milk replacer that includes a direct-fed microbial composition. Feeding the young livestock animals according to this approach may improve animal performance, which may include improvements in total weight gain, feed efficiency and/or starter feed intake. The direct-fed microbial composition may include Bacillus subtilis PB6, about 4.3×109 to about 12.9×109 CFUs of which may be provided daily on a per-animal basis.Type: ApplicationFiled: March 23, 2018Publication date: September 26, 2019Inventors: Bill L. Miller, Samantha Steelman, Daniel Grum, James D. Caldwell

Publication number: 20190166884Abstract: Isoflavone-supplemented dry feed fed to young poultry animals provides total levels of isoflavones in the feed at about 1640 mg/kg feed to about 3890 mg/kg feed, and/or provides an additional about 750 mg/kg feed to about 3000 mg/kg feed. In response to ingesting the isoflavone-supplemented feed, the young poultry animal experiences improved performance.Type: ApplicationFiled: December 6, 2017Publication date: June 6, 2019Inventors: Bill L. Miller, James D. Caldwell

Publication number: 20170202928Abstract: Methods involve feeding livestock animals a milk replacer, where the milk replacer includes non-milk proteins and phytase. Prior to feeding the milk replacer, the phytase may be activated through heat and moisture treatment. The activated phytase may rest for an activation period and the milk replacer containing the activated phytase may be fed to the animal thereafter. The livestock animals may be calves, and may be between about 0 and about 3 weeks of age. In response to ingesting the milk replacer, the calves may increase a rate of weight gain.Type: ApplicationFiled: January 14, 2016Publication date: July 20, 2017Inventors: Bill L. Miller, James D.

Patent number: 7018577Abstract: A method of forming a liner for a passage such as a sewer includes forming panels composing the liner using a neat resin of a first density and a polymer concrete of a second, higher density. The neat resin is inserted into a mold cavity before the polymer concrete and is displaced upwardly by the polymer concrete pour to impregnate a fiber layer disposed along the periphery of the mold cavity. Resulting panels preferably have an offset joint to increase the joint strength between upper and lower panels forming the liner.Type: GrantFiled: February 11, 2003Date of Patent: March 28, 2006Assignee: INA Acquisition CorporationInventors: Walter R. Bilgram, Lynn E. Osborn, James D. Caldwell, Jr.

Patent number: 6929770Abstract: A mandrel-assisted resin transfer molding process and apparatus therefor provides a generally continuous, narrow annular channel between the perimeter of an inner male mold element and an outer female mold element. This channel allows air, heat and vapor to evenly escape and resin to outflow from the mold cavity everywhere around the edge of the part being molded. A very thin resin band forms in the channel is easily trimmed away, leaving the article completely finished on both sides and having a well defined edge that does not require shaping.Type: GrantFiled: September 5, 2003Date of Patent: August 16, 2005Assignee: Caldwell Design and Fabrication, L.L.C.Inventor: James D. Caldwell, Jr.

Patent number: 4958585Abstract: A boat hull is provided with a unique V-shaped bottom surface to increase lift, to reduce drag, and to maximize speed. The deadrise angle of the V-shaped bottom increases progressively from the stern to a point forward of the stern at a rate of 2.degree. to 6.degree. for each four feet of keel length, i.e., at the rate of about 1/2.degree. to 11/2.degree. per foot of keel length. The bottom surface between the stern and the forward point has a generally convex transverse cross section. The keel is substantially straight from the stern to the forward point and then curves upwardly to the bow.Type: GrantFiled: July 11, 1988Date of Patent: September 25, 1990Assignee: Skeeter Products, Inc.Inventor: James D. Caldwell, Jr.
