The Effect of Dietary Energy and Protein Levels on Production in Breeding Female Ostriches. [PDF]
, 2003 1. In a study spanning two breeding seasons, we assessed the effect of different dietary energy and protein levels on body mass, body condition, and egg production of female ostriches. 2.

DIFERENTES DESINFETANTES SOBRE A CONTAMINAÇÃO E DESEMPENHO DA INCUBAÇÃO DE OVOS DE AVESTRUZ
Colloquium Agrariae, 2020 A desinfecção dos ovos incubáveis é um processo importante e necessário, pois no momento da postura os ovos adquirem uma quantidade de microrganismos que se aderem à casca, uma vez que à maioria dos problemas resultantes da invasão de microrganismos deve-

Inter-vertebral flexibility of the ostrich neck:implications for estimating sauropod neck flexibility [PDF]
, 2013 The flexibility and posture of the neck in sauropod dinosaurs has long been contentious. Improved constraints on sauropod neck function will have major implications for what we know of their foraging strategies, ecology and overall biology.

Methane emission by adult ostriches (Struthio camelus)
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2015 Ostriches (Struthio camelus) are herbivorous birds with a digestive physiology that shares several similarities with that of herbivorous mammals. Previous reports, however, claimed a very low methane emission from ostriches, which would be clearly different from mammals.

Avian cerebellar floccular fossa size is not a proxy for flying ability in birds [PDF]
, 2013 Extinct animal behavior has often been inferred from qualitative assessments of relative brain region size in fossil endocranial casts. For instance, flight capability in pterosaurs and early birds has been inferred from the relative size of the ...

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
The Anatomical Record, EarlyView.Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Animal Research and One Health, EarlyView.Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and
