Abstract: The purpose of this study was to determine whether oral use of caper (Capparis ovata Desf.) is safe in Lohmann roosters. About 24 week-old roosters were randomly assigned to control and caper treatment groups (8 per group) and fed a standard diet (14% crude protein and 3000 kcal kg–1 metabolizable energy). Roosters in the control group received 10 mL of tap water, whereas roosters in the treatment group received 1 g of caper per 1 kg of BW suspended in 10 mL of tap water. The experiment lasted for 39 days and treatments were given by oral gavages. Roosters were weighed at the end of caper treatments and blood was taken from the vena brachialis. Organ weights were recorded after sacrifices. No negative effect of caper treatment was observed in hemoglobin, hematocrit, plasma protein, red blood cell count, white blood cell count, biochemical parameters, BW, liver, kidney, spleen, pancreas, gizzard or heart weights. In addition, no apparent changes in these organs were detected by gross post mortem and histopathological examination to suggest toxic effects of oral use of caper for 39 days. Interestingly, caper treatment increased the thrombocyte levels in caper treated roosters. In conclusion, the results suggest that use of caper is safe in roosters.
