| ABSTRACT The growing demand for aquaculture protein suggests seeking biotechnological alternatives that improve the cultivation of species of commercial interest. In this study, Bacillusfirmus C101 was evaluated as a growth promoter and probiotic potential, which was characterized and subsequently administered (106 CFU mL-1 * day) in post-larvae of white shrimp (Litopenaeus vannamei) and rotifers (Brachionusplicatilis sensu stricto). B. firmus C101 was observed to have the tolerance to bile salts, strong phosphatase activity, and antimicrobial activity against pathogens such as Vibrio alginolyticus and Aeromonas hydrophila, among others. On the other hand, after its administration for three weeks to postlarvae of shrimp, it caused a significant increase (p... |

| This study evaluated the effect of feed supplementation (at doses of 0, 50, 100, 150, and 200 mg/kg) with SALUTO®, a microencapsulated blend of essential oils including carvacrol, cinnamaldehyde, 1,8-cineol, and pepper oleoresin, in Nile tilapia (Oreochromis niloticus) broodstock on reproductive and growth parameters during the initial phase of rearing. The growth parameters, somatic indexes and gonadal and hepatic parameters were analyzed. Quantitative parameters of growth, ovary fat and crude protein were not affected by supplementation of the additive. However, an increase in crude protein in the female liver was observed in correlation with increased essential oil levels. The female hepatosomatic index was also correlated with supplementation of... |

| ABSTRACT In the present study, we aimed to assess the toxicity of artemisinin on the haematological system and its effect on the productive performance of broiler chickens. Eighteen-day-old chickens were randomly divided into four groups of 30 chickens (three replicates of 10 broilers/group): control group and three experimental groups: ART5 - diet with 5 ppm of artemisinin; ART50 - diet with 50 ppm of artemisinin; and ART500 - diet with 500 ppm of artemisinin. Artemisinin enhanced the productive performances of broiler chickens at the lowest concentration (5 ppm), but at the highest concentration (500 ppm), it negatively affected weight gain and the feed conversion ratio. The performance characteristics of the chickens whose diets were supplemented with... |

| This study aimed to analyze the economic feasibility of supplement probiotics Bacillus subtilis to “matrinxã” Brycon amazonicus, raised in cages. The experiment was conducted at the Polo Regional Vale do Ribeira, in Pariquera-açu municipality, São Paulo State, Brazil, from February to July 2009. A total of 960 juvenile matrinxã were stocked in twelve 2.7 m³-net cages (1.5 x 1.5 x 1.2 m), in ponds with a total area of 600 m2 and an average depth of 1.50 m. The tests were conducted with a control treatment (T1) and two probiotic doses (T2 = 5 g and T3 = 10 g kg-1 of diet) with four replicates. Results showed that T2 produced better economic performance for matrinxã at the juvenile stage in intensive rearing system. |

| One hundred and ninety-seven isolates of Gram-negative bacteria, comprising 10 genera, were isolated from poultry carcasses at a processing plant in order to investigate resistance to low levels of antibiotics. The samples were taken just after evisceration and before inspection. Most of the isolates were of Samonella and Escherichia. Other genera present were Enterobacter, Serratia, Klebsiella, Kluyvera, Erwinia, Citrobacter, Pseudomonas and Aeromonas. Distinct profiles of antibiotic resistance were detected. Resistance to more than two antibiotics predominated and spanned several classes of antibiotics. Salmonellae and escherichiae were mainly resistant to the aminoglycosides, followed by tetracycline, nitrofuran, sulpha, macrolide, chloramphenicol,... |
