Abstract: Chrysaora fuscescens is a kind of ornamental jellyfish with high economic value, and become to be a very popular giant medusa in aquarium. In the process of captive breeding, it was found that there are a significant number of deformed individuals In this study, we expected to select more suitable feeding combinations by comparing the differences in nutrient composition, we chose two groups of Chrysaora fuscescens domesticated in aquarium, one is the deformity group, and the other is normal group. We measured the conventional nutrients (water content, protein content, fat content, ash content), fatty acid composition and amino acid composition of the two groups. The results showed that the water content, ash content and protein content of deformity group were higher than those of normal group (P < 0.05). The contents of unsaturated fatty acids (C16:1n7, C18:1T, C18:3n3 and C20:4n6) in the deformity group were significantly lower than those in the normal group (P < 0.05). Sixteen kinds of amino acids were detected in both groups, among which the contents of Gly and Glu were the highest. The contents of Phe, Ala, Met and other amino acids in malformed group were lower than those in normal group (P < 0.05). The results showed that there were some differences in nutrient composition between normal and deformity group. In order to achieve the daily requirements, the supplementation of unsaturated fatty acids and the fortification of Glu should be increased in the selection of bait in the future.

Abstract: The research was conducted to observe the effect of a probiotic and organic acid with yeast extract on growth performance (body weight gain, meat yield percentage, and organ weight), hematological (Hb, ESR, and PCV) and biochemical parameters (Urea, Uric acid, and Creatinine) as an indication of kidney function. A total of 18 broiler chicks (Cobb-500) 7 days old were assigned to 3 treatment groups as group A (control group, n=6) was fed with standard commercial feed, and Group B (n=6) was fed with probiotics (Gut-pro®). Group C (n=6) was fed with probiotics, organic acids, yeast extract, and normal commercial ration. Chicks were reared for 35 days. Body weights were recorded weekly. Broilers were sacrificed by cervical dislocation and blood samples were collected for analysis. Serum samples were separated for biochemical tests. Whole meat, liver, viscera and skin were collected and weighed. Total body weight, weight of whole meat, liver, viscera and skin increased significantly (P ˂ 0.01) in birds of group C (organic acid with probiotics) and group B (probiotic) than that of the control group A. Packed cell volume and hemoglobin concentration were increased significantly (P ˂ 0.01) in birds of group B (probiotic) and group C (probiotic and organic acid with yeast extract) than that of the control group A. Erythrocyte Sedimentation Rate (ESR) increased significantly (P ˂ 0.01) in control group A than that of probiotic and organic acid-treated groups. Uric acid and Creatinine concentrations decreased significantly (P ˃ 0.01) in probiotic and organic acid-treated groups than in the control group. Urea levels in group B (probiotic) and group C (probiotic and organic acid with yeast extract) were similar to that of control group A.
