Coccidia oocysts were demonstrated in the faeces of 53 (about 34%) of 156 apparently healthy ostrich chicks. Young chicks had the highest proportion of infestation while those more than 9 weeks old had no oocysts at all in their faeces. These coccidia may be considered no pathogenic since the infected chicks grew normally without any evidence of diarrhoea.
due to the high economic value of ostrich and the farming industry to further promote increased productivity, knowledge in different fields of science, including detailed knowledge of tissue structures vital organs from this animal looks. ostrich’s eye is the cornea closest to the human eye because of the same anatomical features of the human cornea, corneal transplantation can be used ostrich....
Received: Revised: Accepted: February 02, 2015 April 03, 2015 June 15, 2015 This study was to determine the effect of boron supplementation on the morphology of kidney tissue in ostrich chicks. A total of 48 newly hatched ostrich chicks were used and randomly assigned to six groups and exposed to various doses of boric (0, 40, 80, 160, 320, 640 mg/L) in drinking water for 90 days, respectively....

Background & Aim: Only natural materials were used for healing the wounds. As wax honey, ostrich oil and propolis have anti-inflammatory and anti-bacterial effects, this study was launched to investigate their efficacy in skin wound healing. Methods: In this experimental study, 40 Vistar male rats were divided into 5 groups which included a control group, honey wax group, honey wax and propoli...
Damage to ostrich skins in the form of cuts and scratches obtained during the grow-out phase results in lower quality skins that fetch lower prices. This represents major financial losses to the ostrich industry. The stage at which such damage occurs and its persistence to slaughter age, when it affects skin grading, is not known. In this study we assessed the persistence through to slaughter a...
Although locomotor kinematics in walking and running birds have been examined in studies exploring many biological aspects of bipedalism, these studies have been largely limited to two-dimensional analyses. Incorporating a five-segment, 17 degree-of-freedom (d.f.) kinematic model of the ostrich hind limb developed from anatomical specimens, we quantified the three-dimensional (3-D) joint axis a...
