The effect of genotype and sex on carcass characteristics and fatty acid profile of Pekin broiler ducks.

The aim of this study was to compare two different strains of Pekin duck and to answer one scientific hypothesis: 1) Strain and sex influence live body weight, hot and cold carcass weights and carcass portions weights and yields, fatty acid content, fatty acid total cholesterol and α-tocopherol contents of meat. The study used 50 individuals of each strain in comparison (Cherry Valley and Grimaud) equally divided between both sexes), raised in equal rearing and feeding conditions. The results show that, when raised in equal rearing and feeding conditions and slaughtered at matching age, the strain had no significant influence on live body weight at slaughter, warm and cold carcass weights.

Advancements in Performance Monitoring: A Systematic Review of Sensor Technologies in Rowing and Canoeing Biomechanics.

A comprehensive understanding of sports biomechanics is essential for optimizing athletic performance. Recent advancements in sensor technology, particularly inertial sensors, have transformed the landscape of sports performance analysis. These sensors offer profound insights into the kinematic and kinetic aspects of sports, with a particular impact on water-based sports such as rowing and canoeing.

and models define a molecular signature reference for human embryonic notochordal cells.

Understanding the emergence of human notochordal cells (NC) is essential for the development of regenerative approaches. We present a comprehensive investigation into the specification and generation of NC using a straightforward pluripotent stem cell (PSC)-based system benchmarked with human fetal notochord. By integrating and transcriptomic data at single-cell resolution, we establish an extended molecular signature and overcome the limitations associated with studying human notochordal lineage at early developmental stages.

Nutritional value of meat lipid fraction obtained from mallard duck (Anas platyrhynchos) reared in semiextensive conditions for hunting purposes.

The mallard duck or wild duck (Anas platyrhynchos) is the world's most widespread and numerous dabbling duck, being traditionally hunted across many countries in Europe and North America. This study aims to provide a detailed characterization of mallard duck's meat lipid fraction obtained from farmed specimens, reared for hunting purposes, under semiextensive conditions. The mallard's duck meat total lipid content averaged 2.

Effect of Diet Supplementation with Oat Hay and Whole Carrot on Rabbit Growth and Productive Efficiency.

Is it possible to reduce feeding costs in rabbit meat production without compromising rabbit health and productive yield? The study tested four feeding strategies: Control group (CC) fed exclusively with concentrate feed; group CT supplemented with whole carrot; group OH supplemented with oat hay; and Group CO supplemented with oat hay and whole carrot. Each feeding strategy was tested in 20 rabbits, randomly allocated in five cages with four rabbits each. The average daily weight gain (ADG), feed conversion ratio (FCR), and the amount of concentrated feed consumed daily were estimated in all experimental groups.
