“…The ciliated cells are narrow with an expanded apex carrying the cilia. The same results were recorded by Muwazi et al (1982) in ostrich; Wyburn et al (1970) in hen and Fertuck and Newstead (1970) in quail. Our results support the conclusion of Muwazi et al, (1982), that the presence of distended tubules of granular endoplasmic reticulum and dense membrane bounded granules in some ciliated cells are taken as evidence of secretory activity.…”

Nine mature female ostriches (Struthio camelus) aged 37-49 months were used for the present study. The samples were taken during the period from September to November from Almasreya ostrich farm, immediately after sacrification and evisceration. Pieces from the different segments of the left oviduct were taken, then fixed in 10% neutral buffered formalin and Bouin's and Susa solutions for the light microscopic study and in 2 % gluteraldehyde for both scanning and transmission E/M examination.The results obtained were discussed with the available literatures.

“…In the available literature, only few studies on the morphology and ultrastructure of the ostrich oviduct were found ( Muwazi et al,1982, Hicks-Allderdge, 1998, Madekurozwa, 2005and Sharaf , 2005. The present work aims to study the histological, histochemical structure as well as the ultrastructure of the oviduct of ostrich.…”

“…Within the gland acini themselves, there were great variations in staining intensity of the cells to give a mosaic appearance which may relate to granule maturity as well as to the various cell types in glands previously described at the ultrastructural level (Jung et al., 2011; Wyburn et al., 1970); the secretory granules in the present ostrich were large and packed closely together as described by Muwazi et al. (1982) in the domestic fowl.…”

Glycosylation of the reproductive tract of an adult female red‐necked ostrich (Struthio camelus camelus) carrying a fully formed calcified egg in her uterus when accidently killed by a blow to the head was examined using lectin histochemistry on samples from the infundibulum, magnum, uterus and vagina. Glycans in the luminal epithelium and underlying glands were described after staining with 23 lectins after neuraminidase pre‐treatment in some cases. Ciliated and non‐ciliated cells were evident at all levels in the luminal epithelium, the latter full of richly glycosylated secretory granules. The ciliated cells also showed glycosylation and, in the magnum, these cells often stained more intensely than the non‐ciliated cells. High mannose and complex N‐glycans, α1,6‐linked fucosyl and sialic acid residues were present throughout the tract and there was a complete absence of GalNAcα1,3(LFucα1,2)Galß1,3/4GlcNAcß1‐ and rare terminal GalNAcα1‐ residues. Fucose in α1,2‐linkage as H2 antigen and Ley was also rare in the luminal epithelium and completely absent in glands. Terminal galactose was present in the luminal epithelium apart from in the infundibulum. Gland epithelium showed similar glycosylation to the luminal epithelium except in the magnum where there were significant differences and here the glands were packed full of large secretory granules, unlike the glands in the rest of the tract. Each section of the tract had its own specific pattern of glycosylation which could be related to the stage of egg formation.

“…In the mature female ostrich the oviduct is a long (approximately 1.2 m), convoluted, well vascularised organ (MacAlister, 1864;Duerden, 1912;Fowler, 1991;Muwazi et al, 1982). In the crane, the cloaca becomes swollen during this period and the ends of the pubic bones may separate (Gee personal observations, Figure 3).…”

Reproduction in Nondomestic Birds: Physiology, Semen Collection, Artificial Insemination and Cryopreservation

Pioneering work by Quinn and Burrows in the late 1930s led to successful artificial insemination (AI) programs in the domestic poultry industry. A variety of species specific modifications to the Quinn and Burrows massage technique made AI possible in nondomestic birds. Massage semen collection and insemination techniques span the entire range of species from sparrows to ostriches. Also, cooperative semen collection and electroejaculation have found limited use in some nondomestic species.Artificial insemination produces good fertility, often exceeding fertility levels in naturally copulating populations. However, aviculturists should explore other ways to improve fertility before resorting to AI. Artificial insemination is labor intensive and may pose risks to nondomestic birds as well as handlers associated with capture and insemination.Semen collection and AI makes semen cryopreservation and germ plasma preservation possible. Yet, semen cryopreservation techniques need improvement before fertility with frozen-thawed semen will equal fertility from AI with fresh semen.
