Beefing Up Our Prospects, Trevor Boughton, Brad Mccormick Mar 1995

Beefing Up Our Prospects, Trevor Boughton, Brad Mccormick

Journal of the Department of Agriculture, Western Australia, Series 4

In the global fish pond the Western Australian beef industry is a minnow. Production is only 5.5 per cent of Australia's total and around 2 per cent that of the United States. Our output has remained static for the last decade while competition throughout the world has expanded. Moving forward to share the benefits of growing world markets or being left behind is the long-term choice facing the industry, according to TREVOR BOUGHTON and BRAD McCORMICK.


Sharing Information Benefits The Meat Industry, Michael Paton Jan 1995

Sharing Information Benefits The Meat Industry, Michael Paton

Journal of the Department of Agriculture, Western Australia, Series 4

Cronic health problems of livestock, seldom detected on farms, reduce the efficiency of abattoirs and returns to producers. But a major project providing information to producers from abattoirs is indicating how everyone could benefit from feedback.


A Muscle Hypertrophy Condition In Lamb (Callipyge): Characterization Of Effects On Muscle Growth And Meat Quality Traits, M. Koohmaraie, S. D. Shackelford, T. L. Wheeler, Steven M. Lonergan, M. E. Doumit Jan 1995

The present experiment was conducted to determine the effect of the callipyge phenotype on traits affecting muscle growth and meat tenderness. Dorset wethers (n = 40) that were either carriers or non-carriers were fed grain and slaughtered at 169 d of age. Callipyge phenotype did not affect ( P > .05) slaughter weight, hot carcass weight, or weights of the heart, spleen, viscera, kidney-pelvic fat, head, and pelt; however, callipyge lambs had a higher dressing percentage and lighter lungs, liver, and kidneys ( P < .01). Callipyge lambs had reduced fat thickness and marbling score and higher leg scores and longissimus area (34%). Adductor (30%), biceps femoris (42%), gluteus group (31%), longissimus (32%), psoas group (20%), quadriceps femoris (18%), semimembranosus (38%), and semitendinosus (26%) weights were higher in the callipyge phenotype ( P < .01); however, phenotype did not affect ( P > .05) weights of infraspinatus or supraspinatus. Longissimus pH and temperature declines were not affected ( P > .05) …


Delayed-Incubation Method For Microbiological Analysis Of Environmental Specimens And Samples, James S. Dickson, M. H. Brodsky, C. A. Davidson, M. J. Pettis, T. L. Tieso Jan 1995

Delayed-Incubation Method For Microbiological Analysis Of Environmental Specimens And Samples, James S. Dickson, M. H. Brodsky, C. A. Davidson, M. J. Pettis, T. L. Tieso

Five laboratories compared the quantitative recovery of heterotrophic bacteria, yeasts and molds, coliforms, Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus from a variety of naturally contaminated food and water samples, using traditional incubation procedures and a delayed-incubation method. Refrigeration of inoculated media for up to 3 days prior to incubation was shown to be a viable option for many quantitative analyses, but needs to be validated for each application. Some inoculated media withstood refrigeration for up to 7 days prior to incubation without any detrimental effect on the recovery of target cells, while the incubation of other media for similar …


Relationship Of Restriction Fragment Length Polymorphisms (Rflp) At The Bovine Calpastatin Locus To Calpastatin Activity And Meat Tenderness, Steven M. Lonergan, C. W. Ernst, M. D. Bishop, C. R. Calkins, M. Koohmaraie Jan 1995

Relationship Of Restriction Fragment Length Polymorphisms (Rflp) At The Bovine Calpastatin Locus To Calpastatin Activity And Meat Tenderness, Steven M. Lonergan, C. W. Ernst, M. D. Bishop, C. R. Calkins, M. Koohmaraie

Steven M. Lonergan

Restriction fragment length polymorphisms (RFLP) have been identified at the bovine calpastatin locus. The objective of the present study was to determine whether these polymorphisms are related to variations in calpastatin activity or beef tenderness in unrelated animals of mixed breeding. A sample of 83 crossbred steers from sires representing eight different breeds was examined to determine this relationship. A 2.2-kb cDNA coding for domains 2 through 4 plus a 3¢ untranslated region of bovine skeletal muscle calpastatin was used as a probe for calpastatin RFLP. Polymorphisms were found using the restriction enzymes BamHI and EcoRI. Polymorphic restriction fragments for …
