How Do Ratite Meats Compare with Beef?: Implications for the Ratite Industry [PDF]

, 1998
Emu and ostrich meats were compared with beef to identify and quantify their sensory attributes. A sensory panel was used to compare U.S. Department of Agriculture Choice top sirloin beef with emu and ostrich meat, both ground and intact forms. Comparisons of sensory quality and acceptability were made after zero, two, four and six months of frozen ...

Ratite meat

World's Poultry Science Journal, 1998
Due to a belief in the special healthy characteristics of their meat, ratites (ostriches, emus, rheas) are receiving more and more attention as meat producers for developed markets. All three kinds of ratites can be slaughtered by the same technique. At the scientific level, avian nomenclature is applied to the muscles used in meat production, while a ...

Immunostaining of P450c17, Aromatase and Oestrogen Receptor Alpha in Germ and Somatic Cells During Gonadal Development in Greater Rhea. [PDF]

Anat Histol Embryol
ABSTRACT The greater rhea (Rhea americana), the largest bird species in South America, has significant economic value due to its meat, eggs, leather, feathers and oil. However, its lack of external sexual dimorphism poses challenges for reproductive management and breeding programmes.

ENHYDROSS: A New Mechanistic Model Supports the Trans-Oceanic Dispersal Capability of Terrestrial Vertebrates. [PDF]

Ecol Evol
We introduce ENHYDROSS, a new mechanistic model that uses optimal swimming speed and minimum cost of transport to estimate maximum dispersal distances and durations for vertebrates, enabling assessment of long‐distance oceanic dispersal potential. Applied to a range of extant and extinct animals, the model's estimates generally align with observed data;

Improving Phylogenetic Signals of Mitochondrial Genes Using a New Method of Codon Degeneration

Life, 2020
Recovering deep phylogeny is challenging with animal mitochondrial genes because of their rapid evolution. Codon degeneration decreases the phylogenetic noise and bias by aiming to achieve two objectives: (1) alleviate the bias associated with nucleotide
