Goldfish is one of the most popular freshwater cultivated fish because it is one of the freshwater commodities that has economic value and is sold at a price that is affordable to all groups. Ginger is a natural ingredient that can stimulate fish growth. The purpose of this study was to determine the effect of adding ginger to feed and to determine a good dose of ginger for growth and survival rates of carp (Cyprinus carpio). This research was conducted by experimental method using completely randomized design (CRD) with 5 treatments and 3 replications. The treatments given were Treatment 1: 0 grams, without adding ginger / kg of feed (control), Treatment 2: 2.5 grams of ginger / kg of feed, Treatment 3: 5 grams of ginger rhizome / kg of feed, Treatment 4: 7.5 grams of ginger / kg of feed, Treatment 5: 10 grams of ginger / kg of feed. The results showed that the addition of ginger had no significant effect on absolute length growth, absolute weight growth, feed conversion ratio, and feed efficiency, but had a significant effect on the survival rate of goldfish (cyprinus corpio). And a good dose of ginger is in P2 treatment with a dose of 2.5 grams of ginger, because it has been able to show a good survival rate of 100%.

ABSTRACT   Motile aeromonad septicaemia (MAS) in catfish can be done by improving the immune responses through probiotic administration. Co-administering probiotics producing digestive enzymes are expected to have an impact on fish growth. This study was aimed to evaluate the effectivity of probiotics B. megaterium PTB 1.4 and P. pentosaceus E2211 to improve the growth performance and immune response of catfish infected by Aeromonas hydrophila. Catfish with the initial body weight of 7.36 ± 0.21 g were reared in a pond. This study was conducted with five treatments, i. e. K- (without probiotic addition and A. hydrophila injection), K+ (no probiotic addition with A. hydrophila injection), Bm (B. megaterium PTB 1.4 addition and A. hydrophila injection), Pp (P. pentosaceus E2211 addition and A. hydrophila injection), and Bm+Pp (B. megaterium  PTB 1.4 addition and P. pentosaceus E2211 and A. hydrophila injection). The study results showed that Bm, Pp, and Bm+Pp treatments were able to improve the growth performance of catfish including digestive enzyme activity, daily growth rate, feed conversion ratio, and final biomass with the best results was Bm+Pp treatment. The immune response of catfish before and after the challenge test showed better survival rate, higher total leukocytes, phagocytic activity, respiratory burst, and lysozyme activity on Bm, Pp, and Bm+Pp treatment (P<0.05) than the control treatment. In conclusion, the combination of probiotics B. megaterium PTB 1.4 and P. pentosaceus E2211 in feed synergistically improved the growth performance and immune response on catfish against A. hydrophila infection.   Keywords: Aeromonas hydrophila, catfish, growth performance, immune response, probiotics   ABSTRAK   Motile aeromonad septicaemia (MAS) pada ikan lele dapat dikendalikan melalui respons imun inang dengan pemberian probiotik.

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.

Yucca Schidigera

Ammonia is a critical hazardous nitrogen metabolic product in aquaculture. Despite trials for its control, ammonia intoxication remains one of the most critical issues to overcome. In this study, we explored the modulatory effect and potential mechanism by which Yucca schidigera extract (YSE) can ameliorate ammonia intoxication-induced adverse effects on tilapia health and metabolism. A total number of 120 Nile tilapia were evenly assigned into four groups with three replicates each. The first group served as normal control group; the second group was exposed to ammonia alone from the beginning of the experiment and for four weeks. The third group was supplied with YSE in water at a dose of 8 mg/L and exposed to ammonia. The fourth group was supplied with YSE only in water at a dose of 8 mg/L. YSE supplementation succeeded in improving water quality by reducing pH and ammonia levels. Moreover, YSE supplementation markedly alleviated chronic ammonia-induced adverse impacts on fish growth by increasing the final body weight (FBW), specific growth rate (SGR), feed intake and protein efficiency ratio (PER) while reducing the feed conversion ratio (FCR) via improvements in food intake, elevation of hepatic insulin-like growth factor (ILGF-1) and suppression of myostatin (MSTN) expression levels with the restoration of lipid reserves and the activation of lipogenic potential in adipose tissue as demonstrated by changes in the circulating metabolite levels. In addition, the levels of hepato-renal injury biomarkers were restored, hepatic lipid peroxidation was inhibited and the levels of hepatic antioxidant biomarkers were enhanced. Therefore, the current study suggests that YSE supplementation exerted an ameliorative role against chronic ammonia-induced oxidative stress and toxic effects due to its free radical-scavenging potential, potent antioxidant activities and anti-inflammatory effects.

AbstractAn innovative cattle finishing program was tested in which beef cattle were fed on mature zones of standing corn crop in a regulated manner. The corn crop was planted at weekly intervals in a continual rotation year round. When the first planting of corn reached the early dent stage of maturity, nine beef steers (average beginning weight 234.8 ± 7.55* kg) were put in the field inside movable cattle pens. The cattle pens were only large enough to provide one full day of feed and were moved into fresh corn twice a day. The cattle were also provided protein and mineral supplements to balance the corn diet. The test results show that after the initial learning period of a few weeks, cattle consumed practically all the corn ears and about 70 percent of available corn stover. The performance of these steers was compared with that of a control group of nine steers that were fed standard feedlot diet. When feed availability was adequate, there was no significant difference (P < 0.05) in the rate of weight gain between the infield corn-fed animals and the control animals. The test demonstrated that beef cattle could be fed standing field corn for at least three-quarters of the feeding period without affecting the meat quality as measured by rib eye area, fat content, texture and color of lean, and quality grade. All the steers had liver flukes at the time of slaughter and were apparently infected before the start of the experiment. The rate of weight gain and the feed conversion efficiency of both groups of cattle were poorer than normal, possibly because of liver fluke infestation. The results of this test should, therefore, be taken as suggestive rather than definitive. No other major health or disease problem was observed during the in-field corn feeding period.

Abstract The aim of the study was to determine the impact of intramuscular tagging with passive integrated transponders (PIT tags) on the basic condition and hematological and biochemical indexes of the blood plasma of juvenile European perch (initial body weight of approximately 80 g). Throughout the observation period, i.e., for 42 days following PIT implantation, the procedure was not noted to have had a negative impact on fish growth, condition, or feed conversion ratio. The blood plasma biochemical indicators analyzed did not differ statistically significantly between the fish tagged with PIT and the untagged control group. No significant impact from this procedure was noted in the hematological indexes tested. Only with regard to the mean corpuscular hemoglobin (MCH) parameter was the value significantly lower in the fish tagged with PIT than in the control group (P ≤ 0.05). The difference determined was 1.40 pg (28.78 vs. 30.18). The MCH level in the fish tagged with PIT most probably was within the norm for this species. High tag retention (100%) and the lack of any significant impact on condition or hematological and biochemical indexes (with the exception of MCH) permits recommending this tagging method for use in juvenile perch.

Investigations into the performance of Peulh and Maure Zebu breeds of cattle to supplementary feeding of cotton seed and rice bran in addition to grazing natural pasture during the rainy and dry seasons were conducted in the Sahe one of Mali Republic. 96 steers made up of Peulh and Maure Zebu breed with age ranging between 30 and 55 months were grouped into five ._-­the control group grazed on natural pasture alone while four test groups were fed supple­mentary diets in addition to free grazing. Parameters based mainly on feed intake, rate of gain, feed conversion and carcass characteristics showed Maure gained weight significantly (P < - 0.05) faster (318.5g/d) than Peulh (2920) when a feeding trial which lasted 56 weeks was conducted. All steers on test diets performed better than the control except during the second rainy season when a 'compensatory growth' was recorded for the steers under the control. treatment. Younger animals (30 months old) gained weight (337.1g/d) significantly faster (P< 0.05) than the older (55 month-old) ones (273.40). While dressing percentage ranged between 48 and 56, test animals had significantly better dressing percentage of 55.4% (P < 0.05) than the control (48.2%). No diffe­rence was-recorded between the breed or age groups. Animals fed on pasture alone had 10.7% capacity of rumen content as perc­centag€ of carcass weight compared with 7.5% fir test diets.

AbstractThis study evaluated the effects of grape seed extract (GSE) on the growth performance, immune response, and disease resistance of common carp (Cyprinus carpio). Fish were distributed in four groups and fed diets with varying levels of GSE at 0, 10, 20, and 30 g/kg for 56 days. The final length in fish fed with 20 and 30 g GSE/kg diet significantly increased in comparison with the control group (P<0.05). The final weight and weight gain of fish fed with GSE were statistically higher than the control diet, while the feed conversion ratio was lower in GSE groups than the control. Hematological parameters did not statistically enhance with GSE supplemented diets (P>0.05). However, fish fed with 30 g GSE/kg diet displayed a higher WBC count significantly than the other group (P<0.05). The serum total protein and globulin in fish fed with 20 g GSE/kg diet significantly increased compared to the control (P<0.05). A similar pattern was noticed in results for serum and mucus lysozyme activity with a significant increase in fish fed with 20 and 30 g GSE/kg diet compared to the control (P<0.05). Total antibody levels in serum and mucus samples were also increased in fish by dietary GSE with maximum levels by 20 and 30 g GSE/kg diet. Besides, mucus protease activity was higher in fish received 20 and 30 g GSE/kg diet with maximum level shown in fish fed with 30 g GSE/kg diet compared to the control group (P<0.05). Meanwhile, all groups showed higher mucus antibacterial activity against Aeromonas hydrophila with the highest activity in 30 g GSE/kg diet in comparison with the control group. The cumulative mortality was 36.67% when fish fed with 30 g GSE/kg diet and challenged with A. hydrophila. However, the mortality rate was 40% and 53.33% in fish fed 20 and 30 g GSE/kg diet, respectively. This study suggests that supplementation of GSE could significantly enhance the growth performance, immune responses, and disease resistance against A. hydrophila in common carp.

The present study assessed the effect of dietary supplementation with coconut oil (CNO), watercress oil (WCO), and their mixture as promoters of growth, antioxidant status, immunity, and intestinal microbiota in growing rabbits. A total of 120 rabbits were distributed into six groups (20 rabbits/group) receiving a basal diet without supplementation (G1) or diet supplemented with 2 g CNO (G2), 2 g WCO (G3), 0.5 g CNO plus 1.5 g WCO (G4), 1 g CNO plus 1 g WCO (G5), or 1.5 g CNO plus 0.5 g WCO/kg (G6). Live body weight and feed conversion ratio were significantly higher in the G4 and G5 groups than in the other groups. Superoxide dismutase activity and reduced glutathione concentration were significantly improved in the CNO or WCO diets. Supplemental CNO plus WCO at all tested levels produced the best lysozyme and complement 3 activities. Cecal lactobacilli, coliform, Enterobacteriaceae, and Clostridium spp. populations were lower in the group who received the 1 g CNO + 1 g WCO/kg diet than that in the control group. Dietary supplementation of 1 g CNO + 1 g WCO or 0.5 g CNO + 1.5 g WCO/kg had the potential to improve growth, feed utilization, antioxidant status, and immunity, and reduce cecal pathogenic bacteria in rabbits.
