The milk productivity improvement of she-camels requires a good feeding program that should indicate appropriate foods, required quantities, and how and when to distribute them. The aim of this study was to explore the interactions between milk productivity and body variations of dairy camels in response to experimental dietary treatments. The camels received a new diet every 15 days approximately, with higher rate of concentrates and high energy concentration. Results showed that diets with high energy or protein density, UFL (forage unit for milk production), and nutrient waste stimulated the development of body weight at the expense of milk production (p <0.05). Therewith, the inadequate supply of feeds rich in fermentable carbohydrates such as dates (p <0.01) or corn (p <0.05) compromised milk productivity level in favor of ADG (average daily gain) and body reserves deposit. Increasing the level of roughage feed intake had a positive effect on milk production (p < 0.05). According to the results, it is recommended in the feeding of dairy she-camels to maintain a minimum level of roughage at more than 60%. In addition, it is necessary that the energy density (DER) be in the order of 0.91–1.17 maximum (0.78 UFL/kg.DM-dry matter). Taking into account famous nitrogen recycling mechanisms of camels, the protein supply of diets does not seem useful to overcome 63 g PDI/kg.DM (PDI protein digestible in the intestine).
