The aim of the present study was to determine the total phosphorus requirement in the diet of jundiá fry (Rhamdia quelen) in a semi-purified diet. A quantitative experimental research was carried out, using dehydrated albumin as a protein source, with the supplementation of monobasic sodium phosphate at different levels: 0.04; 0.30; 0.47 and 0.70% of total phosphorus (P). 160 fish with an average weight of 1.20 ± 0.53g were used in an experimental or completely randomized design, with four treatments and four replications. The experiment lasted 33 days. To determine the phosphorus requirements for juveniles, body chemical composition, bone mineral composition and productive performance parameters were evaluated. The body chemical composition only the levels of protein did not present significant difference (p˃0.05). The levels of phosphorus, potassium and magnesium in the bones increased linearly, with increased levels of phosphorus in the diet. Based on weight gain and total length, the requirement for phosphorus for juveniles of jundiá (Rhamdia quelen) in a semipurified diet is between 0.53 - 0 5.8% of P-total.

This study aimed to evaluate the Texel lambs’ meat quality fed with increasing levels of crude glycerin (0, 7, 14, and 21% of dry matter) in the diet. Thirthy-two-two non-castrated male Texel lambs were used, with initial weight of 15.9 ± 4.1 kg, using a completely randomized design with four treatments and eight repetitions, per treatment. Upon reaching the average weight of 35 kg, the animals were slaughtered. The meat chemical composition was similar among treatments (P>0.05) and total lipids and crude protein presented averages of 3.47 and 20.05 g 100g -1, respectively. No changes in pH, marbling, color, and water loss under pressure were observed. The shear force did not change among treatments and the texture can be considered soft, with average values of 5.48 kgf. There was a linear (P0.05) were observed for the attributes flavor, tenderness, juiciness, and overall acceptance among treatments. Fatty acids in higher proportions in the meat lamb were to C18:1n-9 (1298.90 mg 100g-1), C16:0 (709.07 mg 100g-1) and C18:0 (433.30 mg 100g-1), with percentages of 42.72, 23.07 and 14.35%, respectively. Significant difference according to the glycerin level in the diet was observed only for the margaric acid (C17:0) with an increasing linear effect, reaching 58.95 mg 100g-1 muscle to the group with 21% crude glycerin, corresponding to 1.77% of total fatty acids. The other fatty acids did not change, and provided a satisfactory result for conjugated linoleic acid (CLA), totaling about 6.1 mg 100 g-1 muscle, corresponding to 0.21% of total lipids. The use of glycerin in the diet for finishing lambs does not alter the characteristics of the meat, maintaining the product quality for consumption.

Background: Oxidative stress from exercise can contribute to damaging cells, increasing heat shock protein 70 (HSP70) and suppressing the immune system in the body. This research aimed to determine the antioxidant potential of red-fleshed pitaya extract on HSP70 and cortisol expression in rats which were subjected to strenuous exercise. Methods: The subjects of this research were 32 Sprague Dawley male rats, aged 3 months, with an average weight of 200 g. Red-fleshed pitaya extract was obtained from methanol extraction process; a maceration technique was performed and the extract was concentrated using an air-drying method. Rats were randomly divided into four groups. Group 1 were subjected to strenuous exercise and treated with distilled water only; while Groups 2, 3 and 4 were subjected to strenuous exercise and treated with 100 mg/kg body weight, 200 mg/kg body weight and 300 mg/kg body weight of red-fleshed pitaya extract, respectively. Strenuous exercises in rats was performed by intense swimming of 20 min/day, 3 days a week for 3 weeks. HSP70 expression and cortisol were measured with Enzyme-Linked Immune Sorbent Assay (ELISA) method. Results: There was a significant reduction of HSP70 (p=0.000) and cortisol expression (p=0.000) between the groups. Also, there was a significant difference in the average decreasing of HSP70 expression between group 4 and either groups 1 or 2 (p=0.000). However, a significant difference between groups 4 and 3 was not observed (p=0.813). Lastly, a significant difference was found in the average decrease of cortisol expression between groups 4 and 1 (p=0.000), 2 (p=0.000), and 3 (p=0.000) respectively. Conclusion: Red-fleshed pitaya is potential to be utilized as antioxidant to decrease the HSP70 and cortisol expression.

Minimizing the high oxygen consumption and energy expenditure of the critically ill is an important therapeutic goal. This study was done to determine if neuromuscular blockade decreases oxygen consumption or energy expenditure more than sedation alone in the mechanically ventilated child. Twelve burned children, with an average age of 5.1- 1.6 yrs, average weight of 22.8 − 6.5 kg, and average burn size of 28.3 − 5.8% of the body surface, scheduled for a planned surgical procedure under general anesthesia were enrolled in this prospective self-controlled study. In conjunction with planned operative procedures and using an intravenous anesthetic technique, the children underwent expired gas collection before and after neuromuscular blockade was induced. Expired gas was collected and analyzed for the fractional concentration of oxygen and carbon dioxide. Oxygen consumption (VO2), carbon dioxide production (VCO2), energy expenditure (EE), and respiratory quotient (RQ) were calculated. We found no significant difference in EE, VO2, VCO2, or RQ between the well-sedated and mechanically ventilated and the well-sedated, mechanically ventilated and paralyzed states. We therefore concluded that neuromuscular blockade does not decrease energy expenditure in the otherwise well-sedated burned child.

Calcium and phosphorous are two important minerals because of their functions for growth and bone mineralization as well as lipid and carbohydrate metabolisms. The study purposes were to determine the effects of calcium and phosphorus with different ratios of nutrient retention and chemical composition changes of juvenile shrimp body. Organism used in this experiment were juvenile tiger prawns with an average weight of 3.43 ± 0.05 g/fish. Stocking density was 6 fish per aquarium (size 60cmx50cmx40cm). This research was formulated according to completely randomized design with four treatments and three replicates. The treatments applied were the ratio of calcium and phosphorus in shrimp food i.e., A (Ca/P=1:0,5), B (Ca/P=1:1,0), C (Ca/P=1:1.5) and D (Ca/P=1:2,0 ). Food was served four times per day i.e. 07.00 AM, 11.00 AM, 15.00 PM, and 21.00 PM.. The juvenile tiger prawns maintained for 8 weeks. The results showed that calcium and phosphorus with different ratios in the diet did not give effect to the retention of nutrients include protein, fat, calcium, and phosphorus. While the provision of calcium and phosphorus in different ratios to changes in body chemical composition includes protein, fat and ash content of juvenile tiger prawns have a significant effect except for crude fiber and BETN not significant. The result indicated that the ratio of Ca and P with a value of 1:1.0 to 1:1.5 gave better effect in changing the chemical composition of juvenile shrimp body.Keywords: tiger shrimp juvenile, retention of nutrients, chemical composition

The study was conducted to investigate the effect of nitrogen application on the yield contributing characteristics, biomass yield and nutritive values of cowpea forage. Five nitrogen levels viz: 0 (T0), 15 (T1), 20 (T2), 25 (T3) and 30 (T0) kg N/ha were applied in 20 plots in a Completely Randomized Design (CRD). The result showed that the application of nitrogen fertilizer had significant (P<0.01) effect on plant height and highest plant height (96.25 cm) was observed at 25 kgN/ha. However, application of nitrogen fertilizer from urea did not show any significant effect on branching of plant. The application of nitrogen fertilizer significantly (P<0.01) increased the green, dry and organic matter, and crude protein yield of cowpea forage. No significant difference (P>0.01) among the groups for chemical composition of cowpea forage was observed due to increasing rate of N fertilizer. Similarly, N fertilization had no affect on OM digestibility and ME content of cowpea forage. From the results of the present study, it may be concluded that the application of N at the rate of 25 Kg N/ha could be used for cowpea forage production.

In terms of control, various natural chemical compounds derived from plants can be used. Like papaya and soursop leaves, the formulation of the problem is whether the combination of soursop leaf extract and papaya leaf extract is effective in controlling S. litura pests and what is the most effective extract concentration. This study used a completely randomized design (RBD) with 5 treatments and 5 replications. Observation variables included symptoms, morphological changes and mortality, the results were analyzed by Analysis of Variance (ANOVA) followed by the Least Significant Difference (LSD) 5% test. The initial symptoms that were seen one day after application of the combination were morphological changes in the test larvae. Such as damage to the body of the larva, change in color, then the larva's body shrinks, when touched the larvae easily fall. The highest mortality was found at the extract concentration of 20% with a mortality rate of 64.79% on the second day. The results showed that the high mortality rate was closely related to the high toxicity contained in the 20% extract concentration. It was concluded that the results of the effectiveness test of the combination of papaya leaf extract and soursop leaf extract were effective. Suggestions for the use of natural materials that are easily available can be used as an alternative to control pests that are environmentally friendly. Furthermore, it is suggested that if you want to increase mortality, you can try increasing the extract concentration.

Proper fish nutrition and adequate feeding are necessary for high fish production. The study was conducted to determine the suitability of M. oleifera leaf meal supplementation to commercial diets on the growth performance of Oreochromis niloticus fry until fingerling size. Seven experimental diets were used with three replicates each arranged in a complete randomized design. Treatments 1, 3 and 5 were given commercial diets only, treatments 2, 4, and 6 with 10% M. oleifera leaves and 90% commercial diets. Treatment 7 was the control with rice bran. Each treatment was stocked with 50 fry with an average weight of 1.76+0.112 and an average length of 47.65+1.78 and feed for two months. Data gathered were analyzed using the One-Way ANOVA to determine significant difference among treatments. Duncan’s Multiple Range Test (DMRT) was used to determine the significant difference between treatment means. All test used 0.05 level of significance. Results showed significant differences among treatments. Treatment 4 had the highest average weight of 6.83+0.145 g, an average length of 65.97+0.251 mm, and survival rate of 86.0+2.646% after eight weeks of culture. Growth and survival of Oreochromis niloticus could be enhanced by adding 10% dried M. oleifera leaf meal supplementation to commercial diet.

Abstract Gouramy (Osphronemus goramy Lac.) belongs to a group of freshwater fish that have an important economic value and has been cultivated as other economic fish. Increase of biomass production in an aquaculture should consider feeding factors. Not every components in the feed can be absorbed in the digestive process. Parts that can not be absorbed by the body will be issued in the form of the feces so it can be determined the value of the digestibility of a feed material. Crude fiber and nitrogen free extract (NFE) digestibilty value is kind of nutrition that can be determinated. This study aims to determine the digestibility value of crude fiber and nitrogen free extract (NFE) in different commercial feed mills in gouramy (Osphronemus goramy Lac.). This study used 3 treatments, P1 ( commercial feed A), P2 (commercial feed B) and P3 (commercial feed C) with 6 replications. Digestibility value measurement method used was taking feces with surgical techniques. Feces retrieval method aims to minimize water contact with feces. The research design used in this study is completely randomized design. Observed variables are digestibility of crude fiber and nitrogen free extract (NFE). Based on the results of the study can be seen that in the used of diffetent commercial feed there is no significant difference (p> 0.05) on the digestibility value of crude fiber and nitrogen free extract.
