Abstract The concept of probiotics is widely applied in the field of aquaculture for their beneficial and friendly influences. In this sense, the role of Saccharomyces cerevisiae on the growth, immune and antioxidative responses of European seabass was tested in this study. Fish were distributed in 3 groups (triplicates) with ten fish in each replicate and fed 0, 1, and 2 g/kg of S. cerevisiae (15×109 CFU/g) for 90 days. Fish fed S. cerevisiae showed higher final body, weight gain, and specific growth rate as well as lower FCR than fish fed the basal diet (P<0.05). The RBCs, WBCs, Hb, and PCV values were increased in fish fed dietary S. cerevisiae when compared to the control (P<0.05). The blood total protein, albumin, and globulin were higher in fish fed S. cerevisiae than the control (P<0.05). Fish fed dietary S. cerevisiae had enhanced phagocytic index, phagocytic, and lysozyme activity comparing the control. In a similar sense, the antioxidative enzymes (SOD, GPx, and CAT) were higher in fish fed S. cerevisiae than the control (P<0.05). However, the level of MDA was lowered (P<0.05) by S. cerevisiae in European seabass. Gene expression of IL-8, IL-1β, GH, and IGF-1 was upregulated and HSP70 was downregulated by S. cerevisiae (P<0.05). It can be concluded that European seabass fed S. cerevisiae at 1-2 g/kg (15×109 CFU/g) diet had markedly enhanced growth, haemato-biochemical, and immune performances.

Abstract This study aimed to evaluate the effect of probiotic (Saccharomyces cerevisiae boulardii CNCM I-1079) supplementation during feedlot adaptation period on performance of Nellore bulls. One-hundred ninety-eight Nellore bulls were used in a completely randomized block design, divided in 22 pens (9 animals/pen). Treatments were: CON – adaptation diet and finishing diet comprised of basal diet (with 28 ppm of monensin); and SCB – same diets as for the previous treatment with monensin plus probiotic (Saccharomyces cerevisiae boulardii CNCM I-1079, ProTernative® 20; Lallemand Animal Nutrition at a dose of 1.0 x 10e10 cfu/animal/d) supplementation. Supplementation was offered for the first 42 days (21 days in the step-up phase and 21 days in the finishing diet with 900 g concentrate/kg DM), then both treatments were fed the same basal diet for another 76d, reaching 118 days in total. Pen was considered the experimental unit. Growth data were analyzed using the MIXED procedure of SAS with Tukey test at 5% significance level, and a linear regression analysis was performed for the dry matter intake (DMI) data. During the first 42 days, average DMI did not differ; however, bulls fed SCB plateaued the curve of at 9.17 kg DMI/d earlier (39 days, R2 = 0.97) than those fed CON (43 days; R2 = 0.96) diets. Final body weight (509.5 vs. 518.0 kg, P = 0.02), total body weight gain (163.7 vs. 170.3 kg, P = 0.01) and average body weight daily gain (1.366 vs. 1.420 kg, P = 0.01) were greater for SCB-fed bulls. Feed efficiency of SCB-supplemented bulls was 8.05% greater than CON (P = 0.04). Probiotic supplementation with live yeast Saccharomyces cerevisiae boulardii CNCM I-1079 during the first 42 days in feedlot contributes to reaching the plateau of DMI curve earlier and improving overall performance of Nellore bulls during the total period.

This study was conducted to elucidate the interaction effects of temperature and dietary lipid levels (2 × 2 factorial experiment) on the growth performance, muscle, and liver composition in adult farmed European sea bass (Dicentrarchus labrax). Two groups of fish (190 g; 60 fish per group) were distributed in 12 tanks in triplicates and kept at two different temperature regimes; one starting at 23 °C and then changed to 17 °C for 61 days, and the other starting at 17 °C and then changed to 23 °C for 39 days. Two commercial diets containing both ~44% crude protein but incorporating different dietary lipid levels, 16.5% (D16) and 20.0% (D20) (dry matter (DM)), were fed to the fish to apparent satiation; the type of diet fed to each fish group remained constant throughout the experiment. Final body weight, weight gain, and specific growth rate were significantly higher for the fish group held at 23 °C compared to the fish group at 17 °C (before the temperature changes), while the dietary fat content did not have any profound effect in both groups. Furthermore, the different temperature regimes did not affect muscle or liver composition, but, on the contrary, dietary lipids affected hepatosomatic, perivisceral fat, and visceral indexes. Feed conversion ratio and specific growth rate were not affected by the dietary lipid level. An interaction of temperature and dietary lipid content was observed in daily feed consumption (DFC) and final body weight (FBW).

The present study was conducted to evaluate the effect of different levels of methionine supplementation on feed intake, nutrient digestibility and growth performance of growing rabbit. Sixteen weaned crossbred New Zealand White (NZW) growing rabbits (30-35 d) were distributed into four treatment groups having four replications in each group using a Completely Randomized Design (CRD). Basal diet composed of green grass (dhal grass) and concentrate mixture which was offered ad libitum basis for 56 days period. Four levels of methionine such as 0.0% (control), 0.15%, 0.25%, and 0.35% were supplemented randomly to rabbits. Results showed that supplementation of methionine did not affect green grass intake. Cumulative as well as daily concentrate and DM intake were significantly (p<0.05) higher for all methionine groups than control group. Final body weight gain as well as daily, weekly and cumulative body weight gains were improved significantly with increasing level of methionine. It was found that methionine had significant (p<0.01) effect on digestibility of DM, CP, NFE and EE but CF digestibility did not differ significantly. Digestibility was improved with increasing the level of methionine. Feed conversion ratio also decreased significantly with methionine supplementation, and 0.25% methionine group showed the best performance among the four treatments.

SUMMARYKnown life cycles of myxosporean parasites have two hosts, but very few life cycles have been disclosed, especially in the marine environment.Sphaerospora dicentrarchiSitjà-Bobadilla and Álvarez-Pellitero, 1992 is a systemic parasite from the European seabass,Dicentrarchus labrax(Linnaeus, 1758), a highly valuable commercial fish. It affects its health, leading to aquaculture production losses. During 2013 and 2014, an actinospore survey was conducted in a total of 5942 annelids collected from a fish farm in Algarve and from the Aveiro Estuary, in Portugal. A new tetractinomyxon actinospore was found in a capitellid polychaete, belonging to the generaCapitellacollected at the fish farm. The tetractinomyxons were pyriform measuring 11·1 ± 0·7µm in length and 7·2 ± 0·4µm in width, and presented three rounded polar capsules measuring 2·4 ± 0·3µm in diameter. The molecular analysis of the 18S rRNA gene sequences from the tetractinomyxons revealed a similarity of 100% with the DNA sequences deposited in the GenBank fromS. dicentrarchimyxospores collected from the European seabass and the spotted seabass in the same fish farm and 99·9% similarity with the DNA sequence obtained from the myxospores found infecting the European seabass in the Aveiro Estuary. Therefore, the new tetractinomyxons are inferred to represent the actinospore phase of theS. dicentrarchilife cycle.

Probiotics, a live microbial feed supplement affects the host animal by improving its intestinal microbial balance. Thus, this study was conducted to determine the effect of probiotic (Saccharomyces cerevisiae) supplemented diets on the performance of broilers chickens during the wet season. Two hundred and fifty five broilers chickens were randomly allotted to five treatments in a complete randomize design (CRD) with three replicate per treatment, each replicate having 17 birds. Saccharomyces cerevisiae was included at 0%, 0.25%, 0.5%, 0.75% and 1% respectively. Feed intake was measured weekly and the birds were weighed once weekly to determine the weight improvement. Data obtained from the study were subjected to analysis of variance. All parameters (final body weight, body weight gain, average daily gain, total feed intake, average feed intake and feed conversion ratio) measured showed significance (P<0.05) differencewhen compared with the birds on control diets. In conclusion, inclusion of baker's yeast in broiler diet improved growth performance of the chickens.

A total of 120 1-day-old commercial Cobb chicks were used to study the effects of Clostridium butyricum (C. butyricum) and/or Saccharomyces cerevisiae (S. cerevisiae) on growth performance, intestinal health, and immune status in broilers. The experimental groups were as follows: G1; basal diet (BD), G2; basal diet (BD) plus C. butyricum preparation at 0.5 g/kg diet, G3; BD plus S. cerevisiae preparation at 0.5 g/kg diet, G4; BD plus 0.25 g/kg C. butyricum preparation plus 0.25 g/kg S. cerevisiae. Results showed that the total body weight gain, feed conversion efficiency, and protein efficiency ratio were significantly higher (p < 0.05) in the G4 group than in the other groups. The mortality percentage was reduced in the probiotic-supplemented groups. The villi height was elongated, and the villus height/crypt depth ratio was significantly increased in G2 and G4 chicks, compared to those in the control. The crypt depth was significantly decreased in all the probiotic-supplemented groups. Hemagglutination inhibition titers for Newcastle disease virus (NDV) were markedly increased in G2 and G4 chicks at 35 days of age, compared to those in G3 and control chicks. These results showed that dietary supplementation of a combined mixture of C. butyricum and S. cerevisiae in an equal ratio (G4) was more effective in improving growth performance, immune status, and gut health of broilers, compared with individual supplementation at a full dose.

This research aims to evaluate the effects of dietary supplementation with Saccharomyces cerevisiae cell wall extract (SCCWE) on growth performance, oxidative stress, intestinal morphology, and serum amino acid concentration in weaned piglets. Utilizing a completely randomized design, 40 healthy piglets weaned at 21 d were grouped into 4 experimental treatments with 10 pigs per treatment group. Treatments consisted of a basal diet (T0), a basal diet with a 0.05% SCCWE (T1), a basal diet with a 0.10% SCCWE (T2), and a basal diet with a 0.15% SCCWE (T3). SCCWE supplementation increased the average daily gain and final body weight compared with T0 (P<0.05). SCCWE in T2 and T3 improved the average daily feed intake and decreased the feed/gain ratio compared with T1 and T2 (P<0.05). SCCWE decreased serum malondialdehyde (MDA) and increased activities of catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD) significantly compared to T0 (P<0.05). SCCWE increased the concentration of Ile compared to T0 (P<0.05). Moreover, the concentrations of Leu, Phe, and Arg were higher in T2 and T3 (P<0.05). These findings indicate beneficial effects of SCCWE supplementation on growth performance, the concentration of some essential amino acids, and alleviation of oxidative stress in weaned piglets.

Abstract We examined the effects of dietary supplementation of a Saccharomyces cerevisiae-based direct-fed microbial on the performance, whole-blood immune gene expression, and plasma metabolome of beef steers during a 42-d receiving period. Forty newly weaned Angus crossbred steers (7 d post-weaning; 210 ± 12 kg of BW) were stratified by BW and randomly assigned to 1 of 2 treatments: basal diet with no additive (CON; n = 20) or a basal diet top-dressed with 19 g of the DFM (PROB; n = 20). PROB (PMI, Arden Hills, MN) is an optimized blend of 6.2 × 1011 cfu/g of S. cerevisiae, 3.5 × 1010 cfu/g of a mixture of Enterococcus lactis, Bacillus subtilis, Enterococcus faecium, and L. casei. Daily DMI and weekly body weights were measured to calculate average daily gain (ADG) and feed efficiency (FE). Expression of 84 immune-related genes was analyzed on whole blood samples collected on days 21 and 42. Plasma metabolome was analyzed on day 42. The data were analyzed using the GLIMMIX procedure of SAS with treatment as a fixed effect and BW as a random effect. Compared with CON, PROB increased or tended to increase final body weight (P = 0.01), ADG (P = 0.04), and FE (P = 0.10). Compared with CON, PROB increased (P ≤ 0.05) the expression of seven immune-related genes involved in detecting pathogen-associated molecular patterns and T-cell differentiation. Plasma metabolome analysis revealed an increase (P ≤ 0.05) in concentrations of ten metabolites involved in protecting the animals against inflammation in steers fed PROB diet. This study demonstrated that supplementation of PROB improved the performance and health of newly weaned beef steers during a 42-d receiving period.

Aim: To rear stunted Labeo rohita fingerlings in cages and determine the optimum stocking density and feeding ration for better growth performance of fishes. Methodology: Eight-month-old stunted fingerlings of Labeo rohita (14.65cm/38.23g) were stocked in floating net square cages at different stocking densities (10, 15, 20 and 25 fishm-2) and fed with different feeding ration (3%, 4%, 5% and 6% of body weight), further reared for 330 days and fed twice a day with commercial floating pellets with 25% crude protein. The study followed 4*4 factorial design and were triplicated for each treatment and level. Results: The study found a decrease in the final body weight, average body weight gain, and specific growth rate with increasing stocking density. The highest final body weight (732.64 g), body weight gain (694.30 g) and specific growth rate (0.89 % day-1) were recorded in 10/m2 stocking density with feed ration of 6% body weight. In contrast to this, fish reared in higher stocking density (25/m2) exhibited poor feed conversion ratio. Fish reared in lower stocking density (10/m2) and fed with 6% feeding ration displayed an enhanced feed conversion ratio, feed efficiency ratio and protein efficiency ratio which indicated that rearing of stunted rohu in intensive cage culture at lower stocking density (10/m2) with higher feeding ration (6%) increase their feed utilization capacity. Interpretation: Rearing of stunted rohu in intensive cage culture is possible, however, the stocking density and feeding ration should be 10/m2 and 6%, respectively, compared to traditional cage practices, in order to reduce stress and to get optimum production. Key words: Cage culture, Feeding ration, Fingerling, Labeo rohita, Stocking density
