Eighteen pregnant dromedary females (Camelus dromedarius) were used to determine the effect of concentrate supplement on growth and reproductive performances in peri-partum period.The females were divided into supplemented (n = 9; S) and unsupplemented (n = 9; C) experimental groups.All animals grazed, with one mature male, 7 to 8 hours per day on salty pasture rangelands.
During night, they were kept in pen, where each female bee by bonnie and neil of group S received 4 kg per day of concentrate supplement during the last 3 months of gestation and 5 kg per day during the first 3 months post-partum.During the last 90 days of gestation daily body weight gain (DBG) was at least tenfold more important in group S than in group C (775 g vs.72 g respectively).
Supplementation affected birth weight of offspring (30.3 kg vs.23.
4 kg) and its DBG (806 g vs.430 g) in group S and group C respectively.During the post-partum period, females in group S gained in weight (116 g per day) whereas females in group C lost more than 200 g per day.
The mean post-partum interval to the first heat and the percentage of females in heat were 29.5 day and 44.4/ vs.
41.2 day and 71.4/ for the C and S groups, respectively.
We conclude that under range conditions, dietary supplementation of dromedary during late pregnancy stage and post-partum period improves color touch 7/97 productive and reproductive parameters.
