The aim of this study was to investigate the serum level of fat-soluble vitamins A, D and E in clinically healthy lactating female camel (Camelus dromedarius) and suckling calf > one-year-old during winter and summer seasons in five main regions of Saudi Arabia. 60 sera samples were collected and tested for vitamins A, D and E levels and the results were statistically analyzed. The statistical mean value of vitamin A was within the reported range but for D and E, there were minor variations. The effect of season was insignificant (p > 0.05) for vitamins A and E in the combined results of the dam and newborn together. This seasonal effect was highly significant in dam serum (p < 0.05). Region effect was significant for vitamin A in the northern area (p < 0.05) and for vitamin E in the southern region (p < 0.05). Correlations analysis revealed significant results in the season vs vitamin A and E p < 0.05. Mean values of vitamins A, D and E in dam and newborn did not observe significant variations however, in the season and regions there were significant variations which can be attributed to the climate difference, availability of balanced rations and camel management in each location of the five main regions of Saudi Arabia. There is a great need for further studies and the consequent development of supplementation programs and camel feed manufacturers awareness of such results is highly recommended.
