objective of this paper was to study the effect of birth season and parity of Maghrabian she-camels as well as sex of their calves on their reproductive and lactation performances under Egyptian condition. Records of 252 she-camels (1-7 parities) were collected during the period from 2014 to 2020. These records including reproductive and milk yield records. Out of 252 records, birth season of 145 animals were in winter and 107 animals in summer. Camel herd raised at the Studies and Development of Camel Production Station, Animal Production Research Institute, Egypt. Results showed that averages of age at conception (AAC) and at calving (AAV) were longer (P<0.05), while average calf weight at birth (CWAB) was lower (P<0.05) winter than summer animals. Number of matings per conception (NMC), days open (DO), gestation period length (GPL), and calving interval (CI) did no differed significantly between winter and summer animals. Lactation period (LPL), and total (TMY) and daily milk yield (DMY)) were not affected significantly by birth season. Averages of AAC, AAV gradually increased (P<0.05) advancing parity, being the shortest at the 1st parity and the longest at the 7th parity. NMC was the lowest (P<0.05) at the 1st parity (2.21 matings), moderate at the 2nd – 4th parity (2.74-3 matings), and the highest at the 5th – 7th parity. DO, GPL, CI, CWAB, TMY, and DMY were not affected by animal parity. CWAB was heavier (P<0.05) in males than females. However, other reproductive and lactation performance parameters wer nort affected by calve sex
