The aim of the study was to evaluate the effects of a trans-galactooligosaccharide prebiotic (GOS) on the growth performance, biochemical blood parameters, and intestine morphometric parameters of common carp. The 60-day-long experiment was performed on one-year-old fish with a mean body weight of 180 g (±5 g). Three diets were used: control diet 1 (C) with no microbiota affecting feed additives, diet 2 (B1) with 1% of prebiotic, and diet 3 (B2) with 2% of prebiotic, in four replications (tanks) per treatment and 25 fish per tank. At the end of the trial, 16 individuals from each group were used for analyses. The study showed that GOS supplementation did not affect growth performance. In turn, the prebiotic had a positive effect on the development of the intestine, and increased the height, width, and surface of the villi in B1 and B2 groups. The content of phosphorus (P) was significantly higher in B1 group compared with B2 group, which indicated that 1% addition of prebiotic causes better absorption of P from the intestine. The other biochemical indicators—namely lipid, protein and hepatic parameters, insulin, and Ca—were not affected by GOS treatment, which may indicate similar metabolic balance of fish in each experimental group. Serum triiodothyronine (TT3) and glucose (stress markers) concentrations were not significantly different among treatments groups. GOS may be recommended as a feed additive for common carp due to its positive effects on fish physiology and development of the gastrointestinal tract. However, our results suggest that 1% diet supplementation causes satisfactory reactions for the abovementioned aspects in comparison to control or 2% supplementation.

The study determined the effect of three different levels of Boswellia serrata tree resin (BSR) supplementation in diets for broiler chickens on the growth performance, selected slaughter analysis, nutrient digestibility, as well as haematology, biochemical and some humoral immunity blood parameters. In total, 200 1-day-old broiler chickens were assigned randomly to four treatments. The broiler chickens were fed diets containing 0 (C), 1.5 (BSR1.5), 2 (BSR2), or 2.5% Boswellia serrata resin (BSR2.5). The BSR treatments improved (P < 0.05) the feed intake and feed conversion ratio at breeding Days 22–35, but did not differentiate the nutrient digestibility in the diets. The best-quality carcass with a high proportion of muscles and low fat content (Control versus BSR diets, linear, P < 0.05) was obtained in broiler chickens fed diets supplemented with 2% and 2.5% BSR. The blood profile was affected by the BSR treatments. The lymphocyte count increased linearly in blood (P < 0.05) along the increasing amounts of BSR. The content of uric acid and aspartate aminotransferase activity in blood plasma decreased upon the BSR supplementation (Control vs BSR diets, linear, P < 0.05; and Control vs BSR diets, linear, P < 0.01, respectively). The resin of Boswellia serrata can be considered as a good botanical feed additive, which can have positive effects on the performance and health of broiler chickens.

Abstract The aim of the study was to determine the effects of prebiotic GOS on muscle histomorphometry and the total lipid, total cholesterol content and fatty acids profile in the meat of common carp. The 60-day-long experiment was performed on one-year-old fish. Three diets were used in the experiment: control diet 1 (C) with no microbiota affecting feed additives, diet 2 (B1) with 1 % of GOS, and diet 3 (B2) with 2 % of GOS. At the end of the trial, 16 individuals from each treatment group were used for the analyses. Fish meat from the B1 group had significantly higher lipid content compared to B2, but neither B1 nor B2 groups were different from the control group. The percentages of SFA, MUFA, PUFA, indexes n-3/n-6, PUFA/SFA, AI and TI, and total cholesterol content were not affected, in contrast to C14:0, C16:1 n-7, C18:0, C18:2 n-6, C20:4 n-6, and total n-6 FA. GOS significantly increased the percentage of normal fibres, while the lower number of fibre atrophy and splitting were observed. The results confirm that diet supplemented with 2 % GOS may be recommended as feed additive in carp nutrition due to positive effects on some fatty acids profiles and muscle microstructure.

AbstractCommon carp (Cyprinus carpio L.) is a dominant fish species in aquaculture, and as it is a stomachless species, absorption and digestion of nutrients take place in the intestine. The aim of the study was to evaluate the effects of a prebiotic on the content of selected minerals found in the meat, gills, and skeleton of common carp. The research applied trans-galactooligosaccharide (GOS) prebiotic produced by enzymatic transgalactosylation of milk lactose by whole cells of Bifidobacterium bifidum. The following diets have been applied: control diet without feed additives (C), diet 2 (B1) with 1% of GOS, and diet 3 (B2) with 2% of GOS. In the freeze-dried samples, concentrations of the analyzed metals were determined using atomic absorption spectroscopy (AAS). The content of phosphorus was determined using colorimetric method. The analyses confirmed that the highest level of Mg was detected in the skeleton of fish fed with 1% GOS (2.51 g kg−1) and was significantly higher compared the control treatment (2.11 g kg−1) (P < 0.05). Zn content in fish meat fed with 1% GOS (35.41 mg kg−1) was significantly higher (P < 0.05) than in the control group (24.59 mg kg−1). The tissue that accumulated the greatest amount of Zn was the gills. GOS had a positive effect on Fe accumulation in the meat, gills, and skeleton. It has been concluded that supplementation of feed with 2% GOS significantly influenced the positive correlations between Mg and P in the meat and skeleton, Fe–Ca correlation in gills, and Fe–Zn correlation in the skeleton.

In the present study, a possible nature immunostimulant and growth promoter—humic substances (HS) originating from Siberian leonardite mineraloid—were tested on juvenile Clarias gariepinus performance. Feed additive was applied onto commercial pelleted feed at four HS levels—0, 1, 3, and 6% w/w (HS0, HS1, HS3, HS6, respectively). Diets were tested in five repetitions (in total, n = 1800 individuals, mean body weight 28.1 ± 6.2 g) for 56 days. Growth and production parameters, fish condition and somatic indices, and overall mortality were evaluated after 14, 28, 42, and 56 days of exposure. Whereas, plasma samples were collected only after 0, 28, and 56 days, when fish health status was assessed with biochemical parameters (total proteins, TP; alanine aminotransferase, ALT; aspartate aminotransferase, AST; lactate dehydrogenase, LDH; cholesterol, CHOL; triglycerides, TAG) and fish antioxidant status with glutathione (reduced glutathione, GSH; oxidized glutathione, GSSG; glutathione ratio GSH/GSSG). Although a significantly positive effect of HS feed additive on growth performance was not found in the present study, moderately positive effects were found regarding biochemical parameters (ALT, AST, LDH, CHOL, and TAG) and antioxidants (GSH/GSSG ratio) that were improved especially in the HS3 group.

Background: The effects of the probiotics vary with the doses and strains used for this reason, a study was conducted over 35 days to determine the effect of live yeast supplementation in the diet of growing rabbits on growth performance and apparent nutrient digestibility.Methods: A total of 60 New Zealand and California rabbits (5 weeks old, average body weight 0.881±0.015 kg) were housed in 30 cages. They were fed with a control diet based on alfalfa and maize or barley grains and supplemented with Procreatin®7 (Saccharomyces cerevisiae CNCM I 1077) or Biosaf® SC47 (Saccharomyces cerevisiae NCYC Sc47) at three doses, namely 0, 6.4, or 12.8 ×109 CFU per kg basal diet.Result: The higher yeast concentration had a positive effect (P less than 0.01) on final body weight (BW), average daily gain (ADG) and carcass weight (CW). However, there were no significant differences in dry matter intake. As a result of this, the feed conversion ratio (FCR) decreased (P less than 0.01). Significant increases (P less than 0.05) in nutrient digestibility (DM, OM, NDF and ADF) were observed with both grains. The use of yeast in maize and barley-based diets of rabbits has positive effects on growth performance and nutrient digestibility.

Probiotic effects on growth performance, carcass traits, blood parameters, cecal microbiota, and immune response of broilers were studied. Two hundred one-day-old male chickens were allocated to one of five treatments (four replicates of 10 birds per treatment): control, and the same control diet supplemented with 0.005%, 0.01%, 0.015% and 0.02% probiotics. Probiotics in feed at 0.01% or higher levels of supplementation improved body weight gain (+12%) and feed conversion rate (-5%) compared with the control. There were no effects on carcass traits, but the relative weights of drumsticks and wings showed increasing and decreasing linear responses, respectively, to probiotic supplementation level. Blood plasma glucose and albumin contents linearly increased (from 167.1 to 200.5 mg dl-1, and from 1.70 to 3.25 g dl-1) with increasing probiotic supplementation. Triglycerides and cholesterol contents were lower in probiotic supplemented treatments (average contents 71.3 and 125.3 mg dl-1 vs. 92.6 and 149.9 mg dl-1 in the control). Probiotics decreased cecal Escherichia coli counts, but had no effects on immunity related organs or immune response. The linear trends, either positive or negative, observed in many of the parameters studied, suggest that more studies are needed to establish the optimal concentration of probiotics in broiler feed.

The growth performance, blood parameters and production cost of two hundred and fifty two (252) Abor acre plus broiler chickens fed sweet orange peel meal (SOPM) with and without enzymes were investigated. The experimental diets consist of control (T ), maize was 0 replaced with SOPM at 15, 20 and 25 % without exogenous enzymes to form T , T and T 1 2 3 respectively, and another supplemented with exogenous enzyme to form T , T and T 4 5 6 respectively. The birds were randomly allocated to seven treatment groups replicated three times to have 12 birds per replicate and were fed experimental diet ad-libitum for eight weeks. Result showed that broiler chickens fed control diet (T ) had significantly (P<0.05) 0 higher final weight (FW) of 2.44kg, weight gain (WG) of 42.91, feed intake (FI) of 86.53, better feed conversion ratio (FCR)of 2.01 and protein conversion ratio (PCR)of 0.44 compared to other dietary treatments. Broiler chickens fed T and T had significantly 1 4 (P<0.05) higher final weight of 1.98 and 1.98 kg, weight gain of 34.69 and 34.71 g and feed intake of 78.35 and 81.63 g respectively while significantly (P<0.05) least values of 1.75 and 1.80 kg final weight, 30.73 and 31.49 g weight gain and 69.47 and 71.84 g feed intake respectively were recorded in broiler chickens fed T and T . Haematological indices namely: 2 5 PCV, RBC, WBC and Hb were not significantly different (P>0.05) but MCV, MCH, MCHC, lymphocytes, heterophil, eosinophil and monocytes differed significantly (P<0.05). Serum biochemical indices namely total protein, albumin, globulin and uric acid were significantly (P<0.05) influenced by the experimental diets. Though, there was no detrimental effect of SOPM and enzyme on production cost as profit was made at all replacement levels of SOPM with and without enzyme treatment, but profit per bird (N) and cost to benefit ratio revealed the superiority of the broiler chickens fed control diet (T ). Based on the results obtained, 0 SOPM can replace maize up to 25 % without posing any deleterious effect on the broiler chickens growth performance, blood parameters and production cost. However, the cost to benefit ratio was compromised with the use of SOPM.

The Impact

Abstract The objective of this study was to evaluate the impact of deoxynivalenol (DON), derived from contaminated corn, on growth performance and blood metabolites. A total of 32 growing pigs (initial BW 73.1 ± 1.2 kg; L337 × Camborough, PIC, Hendersonville, TN) were randomly allotted in individual pens to 1 of 2 treatments: a non-contaminated control diet (CTL) and a diet containing 1.8 mg DON/kg (CTL+DON). Upon analysis, CTL+DON also contained 1.9 mg zearalenone/kg and 1.0 mg total fumonisins/kg. On d 1, blood samples were obtained at 60, 120 and 240 min following resumed access to feed. Pigs had ad libitum access to feed thereafter and for 28 d in total. Data were analyzed using the MIXED procedure of SAS with initial BW, sex and treatment as fixed effects, and blood parameters the repeated measures. Compared with CTL, pigs fed CTL+DON had decreased final BW (102.9 vs 87.5 kg; P < 0.001), ADG (1.06 vs 0.51 kg; P < 0.001) and ADFI (2.97 vs 1.54 kg; P < 0.001). Mycotoxins did not affect G:F (0.35 vs 0.32; P = 0.234 for CTL and CTL+DON, respectively). Compared to CTL, pigs fed CTL+DON had increased levels of blood cholecystokinin, a hormone involved in satiety and digestion (32.1 vs 43.3 pg/mL; P = 0.048), increased ghrelin, a hormone that stimulates appetite and promotes fat deposition (345 vs 654 pg/mL; P = 0.011), a tendency for decreased blood urea nitrogen (19.6 vs 17.1 mg/dL; P = 0.076), and increased creatine kinase (2,826 vs 4,920 IU/L; P = 0.027). No treatment differences were observed for circulating creatinine, glucose, albumin, or alkaline phosphatase. In conclusion, mycotoxin contamination substantially impaired feed intake and growth. Pigs offered mycotoxin-contaminated feed had altered blood parameters related to appetite regulation and nutrient metabolism. However, it was not possible to determine if these differences were due to the mycotoxin contamination or to reduced feed intake.

Thanh, B. V. L., Lessard, M., Chorfi, Y. and Guay, F. 2015. The efficacy of anti-mycotoxin feed additives in preventing the adverse effects of wheat naturally contaminated with Fusarium mycotoxins on performance, intestinal barrier function and nutrient digestibility and retention in weanling pigs. Can. J. Anim. Sci. 95: 197–209. This study was designed to determine the effect of feeding deoxynivalenol (DON) contaminated wheat to growing pigs on growth performance, digestibility and retention of nitrogen (N), phosphorus (P) and calcium (Ca). Secondly, we wished to evaluate the potential of four commercial anti-mycotoxin additives in preventing the adverse effects of DON. Sixty piglets (6.0 kg body weight) were assigned to six different corn-soybean meal-wheat diets (control diet: <0.5 mg kg−1 DON; contaminated diet (DON-contaminated): 4 mg kg−1; and four contaminated diets supplemented with a different anti-mycotoxin additive: DON+GLUC (glucomannan), DON+YBP (yeast, live bacteria, enzymes, plant extracts), DON+ALU (aluminosilicate) and DON+PC (preservation components). Piglets were housed individually in pens for 7 d and then transferred to metabolic crates for urine and feces collection for 7 d. At the end of these 2 wk, mannitol and lactulose doses were given by oral administration. Urine was collected for 24 h for an evaluation of barrier integrity of intestinal mucosa. The piglets were then euthanatized and intestinal samples collected for morphology studies. Feeding DON-contaminated wheat reduced average daily feed intake, average daily gain and G:F ratio compared with the control diet (P<0.05). Only DON+PC diet restored the growth performance of piglets fed DON-contaminated diet. Daily retention of N and P was not affected by DON contamination or anti-mycotoxin additives, but retention of Ca was higher in piglets fed the DON-contaminated diets than the control diet. DON-contaminated diet reduced digestibility of dry matter, gross energy and fat, villi height in jejunum, and recovery of mannitol and lactulose compared with the control diet (P<0.05). Finally, DON concentrations in serum from piglets fed the DON-contaminated diets were higher than in the control diet (P<0.05). Piglets fed DON-contaminated wheat had reduced growth possibly caused by impaired jejunal morphology and decreased digestibility of energy and fat.
