Abstract: A study was conducted in 2 phases to evaluate the effectiveness of 1) the VIAscan Beef Carcass System (BCSys; hot carcass system) and the CVS BeefCam (chilled carcass system), used independently or in combination, to predict Uruguayan beef carcass fabrication yields; and 2) the CVS BeefCam to segregate Uruguayan beef carcasses into groups that differ in the Warner-Bratzler shear force (WBSF) values of their LM steaks. The results from the meat yield phase of the present study indicated that the prediction of saleable meat yield percentages from Uruguayan beef carcasses by use of the BCSys or CVS BeefCam is similar to, or slightly better than, the use of USDA yield grade calculated to the nearest 0.1 and was much more effective than prediction based on Uruguay National Institute of Meat (INAC) grades. A further improvement in fabrication yield prediction could be obtained by use of a dual-component video image analysis (VIA) system. Whichever method of VIA prediction of fabrication yield is used, a single predicted value of fabrication yield for every carcass removes an impediment to the implementation of a value-based pricing system. Additionally, a VIA method of predicting carcass yield has the advantage over the current INAC classification system in that estimates would be produced by an instrument rather than by packing plant personnel, which would appeal to cattle producers. Results from the tenderness phase of the study indicated that the CVS BeefCam output variable for marbling was not (P > 0.05) able to segregate steer and heifer carcasses into groups that differed in WBSF values. In addition, the results of segregating steer and heifer carcasses according to muscle color output variables indicate that muscle maturity and skeletal maturity were useful for segregating carcasses according to differences in WBSF values of their steaks (P > 0.05). Use of VIA to predict beef carcass fabrication yields could improve accuracy and reduce subjectivity in comparison with use of current INAC grades. Use of VIA to sort carcasses according to muscle color would allow for the marketing of more consistent beef products with respect to tenderness. This would help facilitate the initiation of a value-based marketing system for the Uruguayan beef industry.

ABSTRACT.
The allelopathic nature of adult Parthenium hysterophorus L. (parthenium weed) plants, suppressing the growth and development of its near neighbours, has been implicated in its success as an important invader around the world. This study for the first time, evaluates the allelopathic potential of parthenium weed seedlings, species using the ?plant box? method (10). Results showed a species-specific response,often with the growth of native species being more affected than introduced speciesand root growth more affected than shoot growth. The native grasses [curly windmill grass (Enteropogon acicularis L.; 59% inhibition) and cotton panic grass (Digitaria brownii L.; 54% inhibition)] were the most affected, while the introduced [Rhodes grass (Chloris gayana L.; 0% inhibition), buffel grass (Cenchrus ciliaris L.; 8% inhibition) and siratro (Macroptilium atropurpureum (DC.) Urb.; 9% inhibition)] were
the least affected in their root growth. These results suggested that parthenium weed is capable of interfering with the growth of neighbouring seedlings even at very early
stages of growth. The response found for buffel grass may partially explain why this introduced pasture grass has been found successful in suppressing the growth of
parthenium weed in the field. |
