Effects Of Supplementation of Yucca Schidigera to Diet and Its Daily Dose on Some Rumen and Blood Parameters, Live Weight Gain in Lambs

18328

This study was designed to investigate the effects of supplementation of Yucca schidigera (YS) and its daily dose to diet on live weight gain, rumen fermentation, rumen protozoal numbers and blood oxidant-antioxidant balance in lambs. In the study, thirty male lambs aged 10-12 months were used. The animals were equally divided into three groups contained 10 animals per group as control and two experimental groups throughout experimental period lasted 60 days. While the animals in the control group were fed with the basal diet, YS was supplemented 500 mg/kg daily to the basal diet of the experimental 1 group and 1500 mg /kg a three day to the basal diet of the experimental 2 group. In the study lasted 60 days totally, ruminal pH, NH3-N and protozoal numbers were determined in the rumen content samples taken from animals at 30 and 60th days, whereas levels of malondialdehyde (MDA), antioxidant activity (AOA), superoxide dismutase (SOD) and catalase were measured in the blood samples. pH and protozoal numbers in rumen content were not changed by treatments, whereas rumen ammonia nitrogen concentration in the rumen content and MDA level in the blood was reduced significantly at 30th and 60th day by treatments. Treatments increased significantly AOA and unchanged SOD and catalase activity. We concluded that the supplementation of YS to diet as a natural feed additive has a positive effect on rumen nitorgen metabolism and in the protection of animal health by decreasing the oxidative damage caused by free radicals.
