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.

Background: Anthelmintic drugs have been widely used in sheep as a cost-effective meansfor gastro-intestinal nematode (GIN) control. However, growing anthelmintic resistance(AHR) has created a compelling need to identify evidence-based management recommen-dations that reduce the risk of further development and impact of AHR.Objective: To identify, critically assess, and synthesize available data from primary researchon factors associated with AHR in sheep.Methods: Publications reporting original observational or experimental research on selectedfactors associated with AHR in sheep GINs and published after 1974, were identified throughtwo processes. Three electronic databases (PubMed, Agricola, CAB) and Web of Science (acollection of databases) were searched for potentially relevant publications. Additional pub-lications were identified through consultation with experts, manual search of referencesof included publications and conference proceedings, and information solicited from smallruminant practitioner list-serves. Two independent investigators screened abstracts for rel-evance. Relevant publications were assessed for risk of systematic bias. Where sufficientdata were available, random-effects Meta-Analyses (MAs) were performed to estimate thepooled Odds Ratio (OR) and 95% Confidence Intervals (CIs) of AHR for factors reported in?2 publications.Results: Of the 1712 abstracts screened for eligibility, 131 were deemed relevant for fullpublication review. Thirty publications describing 25 individual studies (15 observationalstudies, 7 challenge trials, and 3 controlled trials) were included in the qualitative synthesisand assessed for systematic bias. Unclear (i.e. not reported, or unable to assess) or high riskof selection bias and confounding bias was found in 93% (14/15) and 60% (9/15) of theobservational studies, respectively, while unclear risk of selection bias was identified in allof the trials. Ten independent studies were included in the quantitative synthesis, and MAswere performed for five factors. Only high frequency of treatment was a significant riskfactor (OR = 4.39; 95% CI = 1.59, 12.14), while the remaining 4 variables were marginallysignificant: mixed-species grazing (OR = 1.63; 95% CI = 0.66, 4.07); flock size (OR = 1.02; 95%CI = 0.97, 1.07); use of long-acting drug formulations (OR = 2.85; 95% CI = 0.79, 10.24); anddrench-and-shift pasture management (OR = 4.08; 95% CI = 0.75, 22.16).
