This experiment was conducted to investigate the effect of using hydroalcoholic sage extract after experimental copper poisoning on performance and blood metabolites of Japanese quail, in a completely randomized design with 320 one-day old Japanese quails in 4 treatments with4 replicates and 20 birds per each replicate. Experimental treatments were: 1) control (basal diet), 2) basal diet + 750 mg/kg copper sulfate, 3) basal diet + 10 g/kg sage extract and 4) basal diet with 750 mg/kg copper sulfate and 10 g/kg of sage extract. The feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR) were measured weekly and calculated for starter, grower and whole periods. The results of this experiment showed that in starter period, FI was highest in control group compared to other treatments (P <0.05). In the starter and total periods, the average BWG of birds that received diet contained copper was significantly lower than birds in control and the birds that received diets supplemented with sage extract (P <0.05). In the starter period, the FCR was improved when diets supplemented with sage extract in comparison with the birds that received copper (P <0.05). Higher levels of blood glucose and triglyceride and lower levels of HDL and LDL were observed in birds receiving copper in their diet (P <0.05). The results of this experiment showed that supplementation Japanese quail’s diet with sage extract can improve BWG and FCR in starter period, and it may alleviate harmful effect of copper poisoning.

The effect of partial replacement of barley with sugar beet pulp (SBP) with and without roasted canola seeds (RCS) on the performance, morphology, VFA and digesta pH in the small intestine of finishing lambs was investigated. In this study 24 Arbia male lambs with average body weight of 23.7±2.5 kg were used in a 2 × 2 factorial experiment over 84 days. Treatments were carbohydrate factor (barley or SBP) and roasted canola seed (with and without RCS). Partial replacement of barley with SBP significantly increased average daily gain (P < 0.05). Partial replacement of barley grain with SBP increased thickness of muscle, crypt depth and Brunner’s glands in duodenum and villus height, villous width, villus number, thickness of the epithelium, thickness of muscle, crypt depth and villous height to crypt depth in jejunum and villus height and thickness of muscle in ileum (p<0.05). Feeding lambs with diets containing RCS significantly increased Brunner’s glands,villus number and the thickness of the epithelium (P<0.05). Partial replacement of barely by SBP and adding RCS to diet increased significantly concentration individual VFA, total VFA and digesta pH in duodenum and jejunum. Based on the results, the performance of lambs improved as a result of partial replacement of barley with SBP and addition RCS to diets with high concentrate due to changes in the density of volatile fatty acids, digestive fluid pH of the small intestine and the development of the small intestine tissue morphology.
