Mechanics of cutting maneuvers by ostriches (Struthio camelus).
We studied the strategies used by cursorial bipeds (ostriches) to maneuver during running. Eight ostriches were induced to run along a trackway and execute turns. Ground reaction forces and three-dimensional kinematics of the body and leg joints were simultaneously recorded, allowing calculation of joint angles and quasi-static net joint torques. Sidesteps, where the leg on the outside of the t...
متن کاملPrevalence of antibodies to Toxoplasma gondii in ostriches (Struthio camelus).
Serum samples from 973 ostriches (Struthio camelus) in Canada were examined for antibodies to Toxoplasma gondii by the modified agglutination test incorporating mercaptoethanol and formalin-fixed whole tachyzoites. Twenty-eight (2.9%) of the 973 birds were found to be seropositive for antibodies to T. gondii at titers of 1:25 in 15 birds, 1:50 in 12 birds, and 1:500 in 1 bird. This is the first...
متن کاملGrowth curves for ostriches (Struthio camelus) in a Brazilian population.
The objective of this study was to fit growth curves using nonlinear and linear functions to describe the growth of ostriches in a Brazilian population. The data set consisted of 112 animals with BW measurements from hatching to 383 d of age. Two nonlinear growth functions (Gompertz and logistic) and a third-order polynomial function were applied. The parameters for the models were estimated us...
متن کاملGenotyping of Clostridium perfringens isolated from healthy and diseased ostriches (Struthio camelus)
BACKGROUND AND OBJECTIVES Clostridium perfringens is more prevalent type of clostridia genus isolated from the intestinal tract of ostrich (Struthio camelus). Necrotic enteritis (NE) is a potentially fatal gastrointestinal (GI) disease of poultry and other avian species, which produces marked destruction of intestinal lining in digestive tract caused by C. perfringens. Pathogenicity and lesions...
متن کاملLeukocyte ultrastructure, hematological and serum biochemical profiles of ostriches (Struthio camelus).
In the last decade ostrich farms spread throughout the world as an alternative source of investment. Although previous studies have reported hematology and biochemical values for ostriches from several regions of the world, little information is available regarding leukocyte morphology. This study reports the morphology and ultrastructure of ostrich leukocytes and hematology and biochemical val...
