Use of the in vitro gas production technique to study feed digestibility in domesticated ostriches (Struthio camelus var. domesticus)
In order to enhance knowledge of the nutritive value of ostrich feeds, the in vitro gas production technique was used. Five feeds (corn silage, CS; alfalfa hay, AH; barley, BG; soybean meal, SM; beet pulp, BP) were weighed (~ 1g) in quadruplicate in 120 ml serum flasks and incubated at 39 °C with 75 ml of anaerobic medium and 4 ml of reducing solution. A pool of caecal contents obtained at slau...
متن کاملGastrointestinal parasites of ostrich (Struthio camelus domesticus) raised in Iran
Introduction of ostrich (Struthio camelus domesticus), a new exotic host species to a new ecosystem likeIran, necessitates the study of its infectious diseases including parasitic infestations. For a period of one year, from 2002–03, faecal samples of 254 ostriches on 5 farms located at different parts of Iran, includingGarmsar, Semnan province (n = 85); Nashtaroud, Mazandaran province (n = 29)...
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 کاملMechanics 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...
