ABSTRACT
In this research, two experiments would be conducted. She-camels were selected in the first experiment so that they were of different ages, which were the stage of sexual maturity, the pregnancy period, the production period, the dryness stage. Samples were taken from the udder cells. The current study was jointly planned by the Department of Animal Production, Faculty of Agriculture, Al-Azhar University, Cairo, and the Animal Production Research Institute. The current study was aimed to study the relationship between histological changes in the udder of she-camels at different ages and the hormonal changes associated with these histological changes.  The udder samples of (she-camel's dromedaries) were collected immediately after the slaughter of animals from locals such as Al-Basateen slaughterhouse, Nahia slaughterhouse, and Kardasa. The age of the animals was determined by dentition. After collection, samples were directly fixed in 10 per cent neutral buffered formalin, The most important results obtained were that there was a close relationship between the tissue changes in the udder and the hormonal changes. From this, it could infer the development occurring in the udder through various hormonal analyses. Also, through hormonal analyses, it could assume the expected milk production rate in the season.
