Low levels of added mannanoligosaccharides (MOS) in the feed for juvenile rainbow trout significantly promote growth rate, food conversion and overall culture results. Three levels of added MOS: 0.05%, 0.10% and 0.15% were incorporated in commercial pelleted feed and fed three and later two times per day. The experiment started with juveniles of 48?2.1 grams and lasted 90 days. The best growth result was obtained with the smallest (0.05%) MOS level, if compared to the control group and 0.1% and 0.15% MOS supplemented feed. The growth was improvedby11.5% with 0.05% MOS. The best feed conversion ratio (FCR) of 1.29 was found with 0.05% MOS supplement compared to 1.54 in the control group. FCR in 0.1% and 0.15% MOS treatments was 1.46, also significantly better than in the control group. The experiment shows that 0.05% MOS in trout feed is not fully successful in total elimination of salmonella colonies from fish intestine. But this is achieved with 0.1% MOS after only 30 days of experiment. The results of experiment point that smaller levels of MOS, if compared to previous research, are beneficial for rainbow trout juvenile culture.

Worm meal obtained from worms (Eisenia fetida) raised on waste materials was evaluated for Rainbow trout as a replacement for fish meal at dietary concentrations of 250, 500 and 1 000 g replaced per kg. During the study period none of the diets was detrimental to fish health. The dietary concentrations of 250 and 500 g/kg replacement gave higher growth rates than that of the control group (0 g/kg replacement), the former having consumed less food. The biological parameters of food conversion efficiency and protein efficiency ratio, for these replacement levels, also showed values better than the control diet. Liver somatic index and the chemical composition of fish fillets showed no significant differences between diets, except for a significant decrease in lipid content with increasing worm meal inclusion.

Meal Product

Juvenile rainbow trout Oncorhynchus mykiss diets containing PepSoyGen, a commercially-available fermented soybean meal product, were supplemented with methionine and other amino acids. A fish meal-based control and four experimental diets were used in a 36-day feeding trial; two diets contained 40% PepSoyGen and 10% fish meal, and two diets contained 50% PepSoyGen and no fish meal. Each of these diets was supplemented with either methionine, or methionine and additional amino acids. One mortality was observed during the trial. Overall weight gain, percent gain, and feed conversion ratio were significantly greater for the fish meal control than for any of the PepSoyGen diets, although feed conversion ratios from all of the diets were still below 1. Apparent protein digestibility was significantly less in the fish receiving the control diet compared to any of the experimental diets, and significantly increased with increasing Pep- SoyGen concentrations. There was no significant difference in length, weight, condition factor, hepatosomatic index, viscerosomatic index, or any fish health responses among dietary treatments. Fillet composition, as determined by crude protein, crude lipid, water, and ash, was also not significantly different among fish reared on any of the diets. The supplementation of other amino acids in addition to methionine had no noticeable effect. The results from this study indicate that PepSoyGen with amino acid supplementation can completely replace fish meal in juvenile rainbow trout grower diets over a relatively short time-frame, albeit with some decrease in rearing performance.

The experiment was conducted to compare the effects of different sources of Spirulina and vitamin mineral premix as feed additive on the growth performance of broiler. Two hundred day old broiler chicks (COBB-500) were divided into five groups such as T1-(Feed containing 0.30% Vitamin mineral premix+0.0% Spirulina), T2-(Feed containing 0.15% Vitamin mineral premix+0.15% Spirulina from China), T3-(Feed containing 0.0% Vitamin mineral premix+0.30% Spirulina from China), T4-(Feed containing 0.15% Vitamin mineral premix+0.15% Spirulina from Myanmar) and T5-(Feed containing 0.0% Vitamin mineral premix+0.30% Spirulina from Myanmar) having four replication in each group containing 10 birds/replication. The experiment was conducted for 28 days (Completely Randomized Design) with ad libitum feed and water. Live weight was numerically higher (P>0.05) in T4 in 4th weeks of age. Lower feed intake observed in T3 and T5 which was mainly 50% replacement of vitamin mineral premix by Spirulina. After end of the feeding trial feed conversion ratio (1.66) in control group was higher (P<0.05) than other groups (1.63, 1.64, 1.59 and 1.61 respectively in T2, T3, T4 and T5). Dressing percentage (63.12%), breast weight (21.22%) and thigh weight (8.54%) were higher (P<0.05) in T4 than all other groups. Concentration of total cholesterol in blood plasma (64.42mg/dl) and serum albumin (1.75g/dl) was lower (P<0.05) in T4. It could be concluded that Spirulina from Myanmar is better than China and 50% synthetic vitamin mineral premix could be replaced by using Spirulina from Myanmar for better growth of broiler. Bang.

During the farming of juvenile rainbow trout (Oncorhynchus mykiss), losses can be very high. In aquaculture, various agents are used, such as copper, for the purpose of preventive action and prevention of the appearance of pathogens (ectoparasites, etc.). The aim of this study was to determine the effects of substrate-fixed copper microparticles on the growth and survival of juvenile rainbow trout (Oncorhynchus mykiss) up to the age of 5 months. The experiment was conducted in the Laboratory for Aquaculture of the Faculty of Agriculture, University of Banja Luka, for 142 days in flow aquariums with a 65 l/aquarium volume. The experiment was set up in two groups (150 units/group) with three replicates (50 units/replicate), a control group without copper microparticles (K) and a group with copper microparticles (Cu). The initial weight and total body length (mean ? SD) of rainbow trout in group K were 0.199 ? 0.008 g and 2.876 ? 0.036 cm, and in group Cu 0.197 ? 0.009 g and 2.893 ? 0.038 cm. The average total length and body weight of individuals from the K and Cu groups were similar (p > 0.05). The differences in FCR, CF, SGR and TGC between group K and group Cu were not statistically significant (p > 0.05). Survival of juvenile rainbow trout was high and it was 97.33% in group K and 96.00% in group Cu, and no statistically significant difference was found (p > 0.05). The growth and survival of juvenile rainbow trout in the K and Cu groups were similar.

<p>Simplified diets are based on maximum incorporation of fodder and/or by-products into animal feed, thus minimizing the formulation and the costs. This study aimed to evaluate the possibility of feeding fattening rabbits with a simplified diet composed of only two agro-industrial by-products inexpensive and locally available: brewer’s grain and wheat bran. At weaning (35 days), 68 rabbits were divided into two identical groups (mean weight = 833 g) and housed in individual cages until slaughter (77 days). Each of the two groups (B0 and SF) was fed <em>ad libitum</em> either a commercial pelleted feed (control), or a simplified pelleted  experimental diet "SF" containing 72% wheat bran and 27% brewer’s grain. The feed conversion was within the standards and similar in the two groups (3.55 on average). The growth rate and feed intake of B0 group were 12% higher (P &lt;0.001) than that of the SF group (35.2g <em>vs</em> 31.2 and 128.3 <em>vs </em>113 g/d). The cold carcass yield and the carcass weight were respectively higher (P &lt;0.001) by 4 units and by 9% in the control group. The carcass of SF group was less fatty (perirenal fat: -23%, inguinal fat: -41% and scapular fat:-14%). The economic efficiency was 40% better for SF diet with almost 50 Algerian Dinar more benefit (/kg of meat).</p><p> </p>

Rainbow trout at an average weight of 240 gwere examined for the effect of dietary fructo–oligosaccharides in the diet on their growth and physiological state through selected biochemical parameters of the blood plasma. The prebiotic product Profeed® (experimental group, EG) was administered on a continuous basis at a rate ofg kg−1of pellets for 105 days. The best growth performance for the EG was found in 42 days (363 ± 34.7 gvs. 340 ± 36.7 g, P = 0.003) and in 63 days (387 ± 35.6 gvs. 364 ± 42.3 g, P = 0.011). SGR of the fish from the EG was 0.69% and from the control group (CG) was 0.70%. The feed conversion level was 0.82 in the EG and 0.86 in the CG. Survival rate was 99% (EG) and 98% (CG). The results of the biochemical examination indicate significant differences in the creatinine (28 ± 5.5 vs. 22 ± 3.05 µmol L−1) and the sodium cation (157.9 1.66 vs. 155.7 ± 1.49mmol L−1) level and in the catalytic concentration of alkaline phosphatase (5.18 ± 1.57 vs. 3.43 ± 0.78 µkat L−1). The positive results of the growth and biochemical tests as well as the favourable feed conversion suggest that it would be worthwhile to test higher concentrations of the Profeed®prebiotic product.

Abstract. Several studies have shown that Continuous Performance Tests (CPT) can diagnose Attention Deficit Hyperactivity Disorder (ADHD) better than other tests. Research reporting comparisons of two or more CPT-type tests is scarce. The purpose of the study was to compare the Mathematics Continuous Performance Test (MATH-CPT) with another CPT-type test (CPT II) and a questionnaire (the Brown Scale). The comparison was carried out by looking at correlations among subscales and checking the precision of detecting ADHD. Ninety-five high school and college students participated in the study, 41 with ADHD were the research group and 54 were the control group. The participants performed the two tests and answered the questionnaire. The results showed that the MATH-CPT correctly identified 74.50% of the participants of both groups as compared to the 71.60% of the CPT II. Correlations between the two CPT-type tests were moderate; however, they were similar to correlations found in other studies comparing similar tools. The MATH-CPT, final attention formula, showed significant correlations with the Brown scales, while the CPT II, confidence index associated with ADHD assessment, showed nonsignificant correlations with the questionnaire. The study indicated that MATH-CPT can be used with a clinical population of ADHD and for research purposes.
