The date production in arid countries like Saudi Arabia includes a part of discarded dates for human consumption. These discarded dates could be used as supplementary feeding for livestock. In trials carried out in a camel farm, date blocks were prepared which composed of 50% dates, 40% wheat bran, 5% urea to increase nitrogen level and 5% cement as binding material. Two groups of 7 camels each 2-3 y old received basal diet composed of alfalfa (2kg/100kg LW) and 1 kg of supplementary feed, i.e. market concentrated for control group and date blocks for treated group. The duration of the trial was 4 months. Blood sampling was done every fortnight for determining urea, glucose, AST and ALT and the growth of camels was monitored by regular weighing at sampling time. Weighing and blood sampling were done in the morning before feed distribution. The intake was 1.94 ± 0.19 and 1.85 ± 0.19 kg/100kg LW in control and treated group respectively, and the mean daily weight gain was 407 and 305g/day, respectively, corresponding to a weight gain of 0.43 kg in control group vs 0.32 kg in treated group, i.e. a consumption index of 2.33 and 3.11 kg concentrates/kg weight gain, respectively. There was no significant difference in the blood parameters. In conclusion, date blocks could be safely used for supplementary feeding of young camels as partial substitution for the regular feed.
