Meat productions from sixteen local Portuguese cattle breeds represent high economic and cultural value for local populations. Among these, Minhota is one of the most important on meat aptitude located on the northwest of the country. This breed is used for high-quality meat. This study describes the influence of slaughter age, corresponding veal (6 months) and beef (9 months) and sex, reared i...

—During November 2002, 51 shovelnose sturgeon Scaphirhynchus platorynchus were sexed by ultrasound imaging using a portable ultrasonograph. We identified males with 96% accuracy (N 5 25) and females with 80% accuracy (N 5 25); one hermaphroditic individual was misidentified as a male. Overall, ultrasound imaging was 86% accurate. Sex in postspawned females was difficult to determine, 60% being ...

Authoring of Adaptive Educational Hypermedia is a complex activity requiring the combination of a range of design and validation techniques. We demonstrate how Adaptive Educational Hypermedia can be transformed into CAVIAr courseware validation models allowing for its validation. The model-based representation and analysis of different concerns and model-based mappings and transformations are k...

nutrigenomics applies genomic technologies to study how nutrients affect expression of genes. with the advent of the post genomic era and with the use of functional genomic tools, the new strategies for evaluating the effects of nutrition on production efficiency and nutrient utilization are becoming available. nutrigenomics plays an efficient role in various fields of animal health like nutrit...

Those avoiding red meat represent up to 16% of the UK population whilst the proportion of the UK claiming to be ‘eating less meat’ ranges from 32.5 to 48% (Woodward, 1988; Food Research Association, 1989; The Realeat Survey Office, 1990; Vegetarian Society, 1991). In contrast, total meat production has not varied dramatically over recent years. Production figures reveal that although there has ...

Meat products, especially fish meat, are very susceptible to lipid oxidation and microbial spoilage. In this study, first, gas chromatography mass spectrometry (GC-MS) analysis of Zataria multiflora essential oil (ZEO) components was done and then two concentrations of ZEO, (1% and 2%) and two concentrations of grape seed extract (GSE), (0.5% and 1%) were used in carboxymethyl cellulos...

Background: Nowadays, there is an increase of meat and animal carcass consumption worldwide. Due to the economic value of meat, the likelihood of using unauthorized tissue is possible in meat products. Based on these observations, the aim of the present study was to apply morphological method for detection of unauthorized tissues in processed meat products. Methods: In this study, a total of 20...
