- Abstract:
- ... ObjectivesAssessment of boneless pork loin quality under industrial conditions is used in plants for segregation of product into programs and for export as well as for routine quality control and research. This assessment is usually made on the exposed longissimus on the ventral side of the muscle. However, lighting and bloom time may not be ideal on-line at time of subjective evaluation. It is th ...

- Abstract:
- ... ObjectivesBeef tenderness is a primary quality feature that defines the consumer’s perception of the product quality. Therefore definition of chemical characteristics that contribute to variation in tenderness within a specific USDA grade can help refine our understanding of meat tenderness. The objective of this experiment was to identify novel protein markers for tenderness in Longissimus dorsi ...

- Abstract:
- ... ObjectivesOver the last 30 yr, the average hot carcass weight (HCW) has consistently increased by approximately 0.5 kg per yr. This trend toward increased HCW causes engineering challenges for aging facilities designed when average HCW was 85 kg, in contrasts to today’s average HCW of 95 kg. The rate of carcass chilling is among the primary concerns. Larger carcasses have a smaller surface area to ...

However, whether the animal growth during the finishing period affects the concentration of EC is unknown. The objective of this study was to quantify anandamide (AEA) and 2-arachidonyl glycerol (2-AG) in plasma during different stage ...

However, little work has been done to determine whether addition- al protein is needed in the diet to maximize the benefit of RAC in beef cattle. Objectives of our experiment were to determine if feeding additional CP in conjunction with RAC would improve animal perfor ...

- ... Apoptosis via the intrinsic caspase 9 pathway can be induced by oxidative stressors hydrogen peroxide (H2O2) and N-(4 hydroxyphenol) rentinamide (fenretinide), a synthetic retinoid. Accelerated muscle atrophy and proteolysis in muscle-wasting conditions have been linked to oxidative stress and activated protease systems. Therefore, the hypothesis of this study was that proteolysis of myofibrillar ...
