  This research aims to study the effects of mangosteen pericarp meal (MPM) and vitamin E (VE) on the performance, blood profile, antioxidant enzyme and HSP 70 gene expression of laying hens in tropical environment when supplemented in their diets. In this study, 160 laying hens of Lohman strains were used; they were 24 weeks old and were observed for 11 weeks. They were arranged in a completely randomized design with four treatments and four replications (10 birds each). The treatments consisted of R0 (control diet), R1 (R0+1 g MPM/kg rations), R2 (R0+2 g MPM/kg rations) and R3 (R0+200 mg VE/kg rations). The data were analyzed using analysis of Variance (ANOVA); if there was any significant difference among the treatments, further tested was done using Duncan Multiple Range Test. The results showed that supplementation of MPM and VE in the diet of the hens significantly (p<0.01) increased the activity of the antioxidant enzyme superoxide dismutase (SOD) and decreased the thiobarbituric acid reactive substances (TBARS) values. Supplementing the hens’ diet with MPM and VE did not affect (p>0.05) their performance, blood profile and HSP70 gene expression. It is concluded that supplementing the diets of the laying hens with MPM and VE increased the activity of SOD and decreased TBARS values of yolk.

  The aim of this experiment was to determine blood profile (hemoglobin, hematocrit, red blood cells, white blood cells), differential leucocytes count (neutrophils, lymphocytes, monocytes, eosinophils) and chromium in blood of lactating cows supplemented with organic chromium (Cr) and Ganoderma lucidum in ration. Fifteen lactating cows grouped and allocated in the five treatments in randomize block design, were fed a basal diet composed of 60% grass and 40% concentrate. Supplementation on basal diet as treatment were: A = basal diet (control), B = 3 ppm inorganic Cr in CrCl3.6H2O, C= 3 ppm organic Cr (fermentation product with Ganoderma lucidum), D = Ganoderma lucidum (5 g 50 kg-1 live weight) and E = Organic Cr+Ganoderma lucidum. Blood profile, differentiation of leucocytes and chromium in blood were investigated. The result showed that there were no significant differences on blood profile (p>0.05). Total leucocytes count was 7120±1.44 cell/μl in treatment E to 9270±2.32 cell/μl in control. Also, organic Cr and Ganoderma lucidum supplementation had no significant effect on differential leucocytes counts and chromium in blood (p>0.05). It can be concluded that blood profile, differential leucocytes count and chromium in blood of lactating cows have not been affected by supplementing organic chromium and Ganoderma lucidum in ration.

  Background: The lower farmer profit margins that hinder ramie fiber plantation expansion can be overcome by utilizing the 82% of underutilized ramie plantation byproducts as ruminant feedstuffs. Although fresh ramie leaves are highly palatable for livestock, their availability is seasonal; therefore, the forage should be conserved. Objective: The aim of this study was to compare the capacity of silage and hay to conserved ramie biomass as a substitute for Jawarandu goat rations. Methodology: Three levels of treatments were tested, namely, a control ration (R1), a ration with 10% ramie silage (2) and a ration with 10% ramie hay (R3). Each treatment was repeated three times. Nine female Jawarandu goats with 27±4.68 kg initial body weight were used in this experiment. Feeds and nutrients offered, refused and excreted were measured to calculate feed and nutrient intake and digestibility. Results: The results showed that substitution of the concentrate with ramie leaves in the form of silage led to lower intake of feed and nutrients (Crude Protein (CP) and Nitrogen Free Extract (NFE)) and digestibility (dry matter (DMD), organic matter (OMD) and DCP). Substitution with ramie in the form of hay, however, increased digested feed and nutrient intakes. Although the ration contained ramie hay had a lower digestibility in comparison to the control ration, this could be recovered by the increased intake. Conclusion: Ramie leaves in the form of hay can be used to substitute 20% of the concentrate in Jawarandu goat rations or be included in 10% of total rations without any problem in availability of digested nutrients for the goat.
