| the histidine-rich protamine from ostrich and tinamou sperm. a link between reptile and bird protamines. | we have characterized for the first time the proteins of two different species of palaeognathous birds, struthio camelus australis (ostrich) and nothoprocta perdicaria sanborni (chilean tinamou). similar to what had been previously reported in neognaths, the electrophoretic mobility, amino acid composition, and primary structure of the main protamine (p-ii) component of these two species of birds are similar. however, in contrast to neognathous birds, the protamines from paleognaths display a hi ... | 1999 | 9890896 |
| plasma chemistry reference values in ostriches. | reference values for 18 plasma chemical variables in blue neck ostriches (struthio camelus australis, n = 60, age 24-36 mo) were established for use in veterinary clinical practice using nonparametric statistics. the following values were established for the percentiles p2.5 and p97.5: sodium 147-157 mmol/l, calcium 2.4-4.8 mmol/l, inorganic phosphate 1.3-2.3 mmol/l, chloride 94-105 mmol/l, glucose 10.3-13.7 mmol/l, urea 0.5-0.8 mmol/l, uric acid 351-649 mumol/l, bile acids 8-33 mumol/l, total p ... | 2002 | 11838206 |
| preliminary results on the use of diagnostic ultrasonography as a management tool to quantify egg production potential in breeding ostrich (struthio camelus australis) females. | an ostrich breeding flock, joined as individual breeding pairs (n = 136 pairs), was used to investigate the possibility of diagnostic ultrasonography as a method to predict the reproductive performance of ostrich females during a breeding season. follicular activity was easily detected and quantified by using diagnostic ultrasonography. one to 8 follicles were recorded in 25% of females scanned at the beginning of the 9-month breeding season. at the end of the breeding season, 1-3 follicles were ... | 2002 | 12240768 |

| wild ostrich (struthio camelus australis) reproduction in orbata, a nature reserve in tunisia. | the aim of the current investigation was to determine wild ostrich reproductive behaviour in orbata nature reserve by observing 16 hens and 28 cocks over a seven-year period. intense laying commenced in january, one month after the cessation of the rainy season, and 92% of the eggs were produced during the dry season (january to may, peaking in march). over the seven years, 1,322 eggs were laid in 69 nests, which corresponded to an annual average production of 19.2 +/- 9.1 eggs/nest and 11.8 egg ... | 2009 | 19340601 |
| physical and sensory meat quality of south african black ostriches (struthio camelus var. domesticus), zimbabwean blue ostriches (struthio camelus australis) and their hybrid. | meat derived from three genotypes of ostrich, resulting from breeding south african black (black) ostriches and zimbabwean blue (blue) ostriches as well as their hybrid, was analysed for physical and sensory quality. ostriches of a commercially standard slaughter age of 14 months, raised under the same environment were used. the ph(24) was the highest in the pure blue genotype and therefore meat from this genotype was the darkest and the percentage drip loss and cooking loss the lowest. when com ... | 2008 | 22062765 |
| cholesterol content and fatty acid composition of ostrich meat as influenced by subspecies. | two muscles, the m. gastrocnemius and m. iliofibularis, were excised from the left legs of six red neck (struthio camelus massaicus) and six blue neck (struthio camelus australis) ostriches and analysed for lipid and cholesterol content and fatty acid composition. total lipid (1.43 g 100g ) and cholesterol content (65.63 mg 100g ) did not differ (ps> 0.05) in any muscle between subspecies. although the percentage of some individual fatty acids differed (p < 0.05), the total percentage of satura ... | 1998 | 22061157 |
