چکیده
Introduction The gestation length for the Old World camelids is 13 months. In all mammalian species the embryo starts life as a spherical clump of cells enclosed within a mucopolysaccharide coat, the zona pellucida, which is transparent, tough and elastic. The transformation from this stage (called a morula) to a blastocyst usually occurs soon after the embryo has reached the uterine lumen from the oviduct.

Developmental competence of Dromedary camel oocytes fertilized in vitro by frozen-thawed ejaculated and epididymal spermatozoa
The present study aimed to compare the in vitro fertilizing capacity of frozen-thawed ejaculated and epididymal spermatozoa in order to standardize the semen preparation protocol for camel in vitro fertilization (IVF). Semen samples were collected from 7 Dromedary camels by means of artificial vagina (AV). Ten cauda epididymes were obtained from slaughtered adult camels, isolated, incised and r...
متن کاملIsolation and molecular characterization of partial FSH and LH receptor genes in Arabian camels (Camelus dromedarius)
Very little is known about LHR and FSHR genes of domestic dromedary camels. The main objective of this study was to determine and analyze partial genomic regions of FSHR and LHR genes in dromedary camels for the first time. To this end, a total of 50 DNA samples belonging to dromedary camels raised in Iran were sent for sequencing (25 samples of each gene). We compared the nucleotide sequences ...
متن کاملBlood, Milk and Meat Vitamin D in the Dromedary Camel
In ruminants, circulating vitamin D levels may be influenced by photoperiod, nutrition, physiological stage, ambient temperature, attitude and season, whereas, in meat, vitamin D content may be impacted by vitamin D status of animal, ageing and cooking. The information on nutritional value of camel milk and meat is largely available, but, there are very few reports evaluating the vitamin D leve...
متن کاملParathyroid Hormone-Related Peptide and Vitamin D in Phosphocalcic Metabolism for Dromedary Camel
In mammals, phosphocalcic and bone metabolisms are mainly regulated by parathyroid hormone, parathyroid hormone-related peptide (PTHrP) and 1α,25-dihydroxyvitamin D or calcitriol. In camels, circulating levels of calcitriol are 10 times higher than those determined in other ruminants and further increase during early lactation. Calcitriol and parathyroid-related peptide stimulate intestinal abs...
متن کاملReproduction in the one humped camel (Camelus dromedarius) in semi arid Nigeria
This review examines the one humped camel (Camelus dromedarius) a considerable number of the dromedary about 50,000 is found in the semi-arid part of Northern Nigeria. Apart from the wide use of the camel as a draught animal the camel now serve as a source of milk, meat and hide in this region, these notes examines the anatomical basis of reproduction, pregnancy, and its diagnosis, fertility, a...
