The one-humped camel, Camelus dromedarius, is an important pack and ride, dairy and meat animal in semi-arid northeastern Nigeria. This study was carried out to document reproductive information for scientists and farmers on camel rearing for improved productivity. A structured open-ended questionnaire on herd growth parameters and constraints of camel-rearing in the region was administered to 147 respondents. Results showed that most camel owners were middle aged, married, Arab men with over 20 years of experience in camel-rearing. The camels were made up of predominantly mixed breeds originating from eastern and northern Africa. Sexually matured heifers are detectable at three years of age, have good body conformation and are receptive to bulls during estrus. They have a long rutting period that stretched from rainy to harmattan seasons (July to January). Length of gestation is 13 months, and pregnancy is detectable by observing a successfully mated cow raising her tail on being approached by a bull at two weeks into pregnancy or the distension of the abdominal region towards mid pregnancy. Up to 60% conception rate was reported while age of cow at first parturition was five years. Other herd growth parameters reported include calf mortality rate of up to 40%, milking duration of one year and productivity of at least 10 calves per cow per life time. Only 4% of respondents in this study consult veterinary care while few (23%) respondents helped the dam to suckle its new born. Abortion, biting flies, trans-border conflicts and armed banditries were the major constraints to camel production in the study area. It was concluded that despite the knowledgeability of camel herders in this study, there appears to be poor herd management that needs to be addressed by adequate education and access to veterinary care in order to improve productivity.
