Review of present knowledge on machine milking and intensive milk production in dromedary camels and future challenges

The camel dairy industry has gone through major development in the last decade. The world's first large-scale camel dairy farm was established 10 years ago in Dubai, United Arab Emirates, and since then, several commercial and scientific projects have been started, and more studies have been published demonstrating increasing interest in camel milk. The aims of this paper are to summarize relevant published data on factors influencing milk production under intensive management, compare those with our own observations obtained from Emirates Industry for Camel Milk and Products (EICMP), and highlight areas of research that are indispensable for further development. As in other species, the most important factors influencing milk yield are genetic and individual variation, age, parity, stage of lactation, nutrition, management, season, photoperiod, etc. However, the precise role of the various factors has not been thoroughly studied in camels and based on our understanding of the basic physiological processes, endocrine control is minimal. In addition, machine milking of dromedaries is still at early stage and requires research for improvement of the technology and defining factors affecting and improving milk ejection. The role of environment (like photoperiod, nutrition) should also be investigated as there is significant annual variation both in milk quantity and quality that might influence the processing characteristics of raw camel milk. The large pool of animals and thoroughly recorded data at EICMP provide an excellent opportunity for increasing milk production and improving milk quality using various methods, like feeding, management, reproduction, selection, and breeding.
