Abstract. The aim of the present study was to evaluate the effect of the dietary black pepper extract supplement on the survival rate, weight gain, feed conversion ratio (FCR), economic efficiency (ECR) and blood biochemical parameters of rainbow trout, cultivated in a recirculation system. One hundred and twenty rainbow trout were distributed in two experimental variants, with two replicates of 30 fish per each. The average initial live weight of fish from the control group (C) and experimental group (P.n) were 41.55±7.96 g and 41.23±8.38 g, respectively (p>0.05). Trouts were fed extruded feed with granule size of 2 mm. Through lubrication of feed granules with 5 ml sunflower oil per 100 g feed, rainbow trouts from group P.n were supplemented with 1% powdered black pepper extract, whereas control rainbow trouts (С) received feed lubricated with the same amount of sunflower oil. Fish were fed 3 times/daily with the diet, based on 3% of biomass. The trial period was 60 days. Survival rate in trouts from both experimental groups was 100%. At the end of the trial, average live weight of fish from group P.n was by 5.84% higher compared to that of control fish the average weight of which was 117.25±19.15 g, yet differences were not statistically significant (p>0.05). The average individual weight gain of control rainbow trouts was 75.70±11.53 g, which was inferior to that of P.n fish by 8.65% (p>0.05). Better FCR was demonstrated in trouts from the group supplemented with 1% black pepper extract – 0.98±0.02, which was by 10.20% less compared to control fish (p<0.01). The addition of 1% black pepper extract to the feed of rainbow trouts tended to result a trend in better growth performance parameters in this species. ECR of group P.n was by 3.98% better than that of the control fish, which showed an ESR value of 1.51. Blood biochemical parameters of fish from both groups were not consistently different.

Aim: This study aimed to evaluate the effect of dietary monosodium glutamate (MSG) on growth performance and blood biochemical parameters of rainbow trout (Oncorhynchus mykiss W.). Materials and Methods: A total of 200 trouts were allotted in five experimental groups (n=40) that for 60 days received feed supplemented with MSG at the following levels: 0% (K) or 0.5% (E) or 1% (F) or 3% (G) or 5% (H). Results: The average initial weight of trouts was 116.68±1.51 g (K), 116.58±1.33 g (E), 116.43±1.39 g (F), 117.40±1.47 g (G), and 115.95±1.88 g (H). At the end of the trial, control fish (K) had the lowest live weight (242.90±3.87 g) compared to Groups E (252.70±5.69 g), F (250.93±4.82 g), G (248.25±4.98 g), and H (247.95±4.74 g). Feed conversion ratio (FCR) of control group (K) was higher (1.11±0.02) versus FCR values established in Groups E (1.03±0.01), F (1.04±0.02), G (1.07±0.03), and H (1.06±0.02). Albumin, aspartate aminotransferase, gamma-glutamyl transpeptidase, alkaline phosphatase, phosphorus, magnesium, and triglyceride exhibited statistically significant differences versus controls. Conclusion: The results from the study showed that dietary supplementation of rainbow trouts with MSG increased live weight and reduced FCR. The optimum level of MSG recommended for addition to feed was 0.5%.

Abstract. The aim of the present study was to evaluate the effect of the dietary nutmeg extract (Myristica fragrans) supplement on the survival rate, weight gain, feed conversion ratio (FCR), economic efficiency (ECR), blood biochemical parameters, chemical composition and fatty acid profile of rainbow trout (Oncorhynchus mykiss W.), cultivated in a recirculation system. One hundred and sixty rainbow trouts were distributed in two experimental variants, each with two replications with 80 fish in one group. The average initial live weight of trouts from control (C) and experimental (E) groups was 13.43±0.33 g and 13.46±0.29 g, respectively. Fish were reared in concrete tanks with effective volume of 0.8 m3, part of a recirculation system. Trouts were fed „Aqua garant UNI“ extruded feed produced by Garant-Tiernahrung Gesellschaft m.b.H. – Austria, with pellet size of 2 mm. The feed of fish from the experimental group was supplemented with 1% powdered nutmeg extract (P.I.C.Co LTD), by lubricating the pellets with 5 ml sunflower oil/100 g feed. Control rainbow trouts received feed lubricated with the same amount of sunflower oil. Fish from both groups were fed 3 times daily and their ration was 3% of body weight. The experimental period lasted 60 days. The dietary supplementation of rainbow trouts with nutmeg extract had a negative impact on growth performance and economic efficiency of farming of the species. Final live weight and average individual weight gain were lower, and FCR and ECR values were inferior vs controls. The nutmeg extract had also an adverse effect on water content and dry matter of meat from supplemented fish. A positive effect was demonstrated only on meat fat content, which was substantially lower compared to that of control fish. Despite the higher SFA as well as lower UFA, MUFA, PUFA, n-6 and n-3 fatty acid content of trout meat that received nutmeg extract with feed, the PUFA/SFA and n-6/n-3 ratios remained within the favourable range for human nutrition, e.g. >0.4 and <5, respectively.

The objective of this study was to evaluate the increasing levels (0, 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6%) of black pepper in diets for laying hens on performance, egg quality and blood biochemical parameters. Hissex White hens (n=168) at 30 weeks of age were used. The experimental method was completely randomized with seven treatments with four replicates of six birds each. Estimates of black pepper levels were determined by polynomial regression. The performance showed no significant differences (p > 0.05). The eggshell percentage was significantly influenced (p < 0.05), in which the level of 0.30% inclusion impaired eggshell quality. Triglycerides level increased significantly (p < 0.05), according to increasing levels of black pepper in the diet. It can be concluded that black pepper can be used in diets for laying hens as phytogenic additive without harming the performance. However, this inclusion causes a reduction in eggshell percentage and an increase in the level of triglycerides in the bloodstream.

The purpose of this study was to follow out the influence of the prebiotic Salgard and of an herb mixture (rosemary, thyme, basil, oregano and cinnamon) on the growth performance and blood biochemical parameters of Pekin ducklings in an organic production system. In this study, 72 one-day-old Pekin ducklings reared up to the age of 63 days were used. They were divided into 3 groups of 24 birds each and sexed (12 ?and 12 ?) as followed: group I (control) fed a standard feed; group II - fed the same feed supplemented with the prebiotic Salgard at a concentration of 0.15 %, and group III - fed the same feed supplemented with 0.15 % of a herb mixture in an equal proportion (0.03% of each herb - rosemary, thyme, basil, oregano and cinnamon) from the first day of age to the end of the experiment. The individual live weight of the birds and the feed conversion ratio were controlled throughout the experiment at 1, 28 and 63 days of age. By the end of the study, blood serum ASAT, ALAT, GGT, triglycerides (TG), total and HDL cholesterol, and creatinine were assayed. The addition of Salgard to the feed of Pekin ducklings increased live weight with 4.94 % in males and with 4.67 % in females. The addition of the herbal mixture of rosemary, thyme, basil, oregano, cinnamon to the feed had a positive effect on the live weight. It is increased with 3.75 % in males and insignificantly in females. A significant reduction in the blood serum concentrations of triglycerides (?<0.01) and total cholesterol (?<0.01) was established, which could be related with the anti stress effect of the herbal mixture on Pekin ducklings.

Background: Seaweeds are rich in complex carbohydrates, proteins and low molecular weight nitrogenous compounds, lipids, organic minerals, vitamins and pigments. The aim of the study is to evaluate the effect of supplementation of seaweed formulations on haematological, blood biochemical parameters and immune response of crossbred calves. Methods: A total of 18 male crossbred calves (130±7.56 kg live weight) were divided into 3 groups of 6 each based on complete randomized design. Calves in control (T0) was fed on standard diet, while treatment groups: T1 and T2 were supplemented with AF-KWP or AFRD-5 at the rate of 4% of concentrate mixture with 1% calcium carbonate and 1% dicalcium phosphate replacing mineral mixture and common salt offered in T0. The experiment was conducted for a period of 240 days. Blood was collected from each calf on 0, 100 and 200 days of experimental periods. Result: Concentration of Hb, PCV and RBC count was significantly higher in T1 and T2. Supplementation of seaweed increased significantly (P less than 0.001) the lymphocytes to neutrophil ratio. Serum total protein, albumin (A), globulin (G) and A:G ratio were comparable. Humoral immune response was significantly higher (P less than 0.001) in T1 and T2. Study concluded that supplementation of seaweed formulations of T1 and T2 improved erythropoiesis, alleviate stress and increased humoral immune responses in crossbred calves and recommend as replacement to mineral mixture and common salt.

Blood biochemistry parameters are valuable tools for monitoring fish health. Their baseline values are still undefined for a multitude of farmed fish species. In this study, changes in the blood profile of rainbow trout females (Oncorhynchus mykiss) from three farms were investigated using different biomarkers during the summer season. In the given context, the main water physicochemical parameters were investigated and twelve biochemical parameters were measured from blood samples of rainbow trout reared in the Fiad, Șoimul de Jos, and Strâmba farms. We selected these farms because the genetic background of the rainbow trout is the same, with all studied specimens coming from the Fiad farm, which has an incubation station. Forty-five samples were collected monthly (May to August) throughout summer to observe the changes in the blood profile of rainbow trout. Principal component analysis showed a clear separation both among the studied farms and months. Furthermore, significant correlations (p < 0.05) between the majority of the biochemical parameters were found, indicating that the environmental parameters can influence several blood parameters at the same time. The present study provides several useful norms for assessing the welfare of rainbow trout, indicating that the relationships among different parameters are important factors in interpreting the blood biochemical profiles.
