Patent number: 6268202Abstract: Strains of the aerobic mycoparasitic fungus Coniothyrium minitans having high levels of &bgr;-glucanase activity have been obtained. Preferred strains have been deposited at the American Type Culture Collection under accession numbers 74415, 74416, 74417, 74418, 74419, 74435 and 74436. Methods for mutagenizing C. minitans 74415 and obtaining strains having &bgr;-glucanase activity are provided.Type: GrantFiled: July 10, 1998Date of Patent: July 31, 2001Assignee: Her Majesty the Queen in right of Canada as represented by the Department of Agriculture and Agri-Food CanadaInventors: Hung Chang Huang, Kuo Joan Cheng, Jennifer L.

Patent number: 6177612Abstract: Matrix attachment regions isolated from the 5′ flanking region of endosperm-specific storage protein genes of monocotyledonous plants are provided. An exemplified matrix attachment region is derived from the 5′ flanking region of the Bx7 gluten gene of Triticum aestivum. Recombinant nucleic acid molecules and plant vectors containing such recombinant nucleic acid molecules include DNA constructs having a promoter, a coding sequence, and a poly(A) addition site, the DNA constructs operably linked to at least one of the matrix attachment regions. Gene expression in transgenic plants, preferably monocotyledonous cereal crop species, is improved by transforming plants with such recombinant nucleic acid molecules.Type: GrantFiled: April 21, 2000Date of Patent: January 23, 2001Assignee: Her Majesty the Queen in right of Canada, as represented by the Department of Agriculture and Agri-Food CanadaInventors: Mark Carlyle Jordan, Christof Rampitsch, Marie Sylvie Jacqueline Cloutier

Patent number: 6137032Abstract: A xylanase gene, denoted xynC, encoding a novel xylanase (XynC) obtained from the anaerobic fungus Neocallimastix patriciarum is provided. The DNA sequence of the xynC gene is also provided. Transformation of microbial and plant hosts with the xynC gene is described. The xynC gene may be used to design probes for use in hybridization experiments to isolate xylanase genes from other anaerobic fungi. The xynC gene has been used to construct an oleosin-xynC expression construct encoding an oleosin-xylanase fusion protein which retains xylanase activity. Transgenic Brassica napus (canola), transformed with the oleosin-xynC expression construct, expresses the oleosin-xylanase fusion protein which is immobilized in the oil-body membrane of the B. napus seeds. Canola meal, the protein-rich residue left after canola oil is extracted from canola plants, when derived from the transgenic B. napus of the present invention, retains substantial xylanase activity, making it an ideal animal feed supplement.Type: GrantFiled: September 7, 1999Date of Patent: October 24, 2000Assignee: Her Majesty the Queen in right of Canada, as represented by the Department of Agriculture and Agri-Food CanadaInventors: Kuo-Joan Cheng, Leonard Brent Selinger, Jin-Hao Liu, Youji Hu, Cecil Wallace Forsberg, Maurice Martin Moloney

Patent number: 5728675Abstract: The invention relates to an antemortem stress supplement for livestock containing one or more sources of electrolytes including sodium, potassium and magnesium, one or more sources of amino acids including alanine, lysine, phenylalanine, methionine, threonine, leucine, isoleucine, valine, and glutamate, all in a bypass form; and a source of tryptophan.Type: GrantFiled: June 5, 1995Date of Patent: March 17, 1998Assignee: Her Majesty the Queen in Right of Canada as represented by the Department of Agriculture and Agri-Food CanadaInventors: Allan L. Schaefer, Stephen D. Morgan Jones, Richard W. Stanley, Ian K. S. Turnbull, John R. Johanns

Patent number: 5720971Abstract: Fibrolytic enzyme supplements for increasing the digestibility of legume forages and grain feeds for ruminants, a method of treating legume forages and grain feeds with fibrolytic enzymes, and feed compositions consisting of feed materials treated with a mixture of fibrolytic enzymes are provided. The enzyme supplements do not pre-digest the feed material but assist in the colonization of feed particles in the rumen by ruminal microbes. The fibrolytic enzyme supplements consist of mixtures of cellulase and xylanase in certain preferred ratios and levels which are dependent on the feed material to be treated. The cellulase and xylanase are dissolved in a buffer solution and sprayed onto dry legume forages or grain feeds. The feed material is then incubated for at least three hours to allow the enzymes to be absorbed into and adhere to the feed material. The resulting feed compositions remain stable for at least one year against predigestion.Type: GrantFiled: July 5, 1995Date of Patent: February 24, 1998Assignee: Her Majesty the Queen in right of Canada, as represented by the Department of Agriculture and Agri-Food CanadaInventors: Karen A. Beauchemin, Lyle Rode, Vincent J. Sewalt

Patent number: 5595444Abstract: The invention provides methods of detecting poor meat quality in live animals using infrared thermography. Animals from a group of live domestic animals such as cattle or swine are scanned to produce thermographic images. The images are then statistically analyzed to determine a measure of central tendency such as the mean temperature for each animal's image and for all of the images in the group. A measure of dispersion from the measure of central tendency, such as standard deviation is determined. Then, animals are rejected as having a high probability of producing poor meat quality if the measure of central tendency for that animal's temperature differs from the measure of central tendency for the group by more than 0.9 standard deviations. Alternatively a set percent of animals are rejected, preferably up to 20%, these being animals whose measures of central tendency differ the most from the measure of central tendency for the group.Type: GrantFiled: October 16, 1995Date of Patent: January 21, 1997Assignee: Her Majesty the Queen in right of Canada, as represented by the Department of Agriculture and Agri-Food CanadaInventors: Alan K.
