Os objetivos deste trabalho foram calcular a CL (I) 50-96h do inseticida organofosforado paration metílico e do biopesticida azadiractina para alevinos e juvenis de pacu ( P. mesopotamicus). Também pretendeu-se avaliar o efeito do peso corpóreo sobre a toxicidade aguda do paration metílico e do neem para o pacu, bem como classificar o risco ambiental do uso de paration metílico e do neem para o controle de parasitas e patógenos de pacu. Foram realizados dois experimentos, em condições laboratoriais, para a determinação da concentração letal (CL (I) 50-96h). A CL (I) 50-96h calculada do paration metílico foi de 3,97 mg/L para os alevinos e de 9,89 mg/L para os juvenis. Para a azadiractina foi de 1,20 mg/L para os alevinos e de 1,18 mg/L para os juvenis. As concentrações de 1,0 mg/L de paration metílico para os alevinos e de 7,5 mg/L para os juvenis e as de 0,29 e 0,59 mg/L de azadiractina não provocaram mortalidade nos animais expostos e podem ser utilizadas como referência em estudos de controle de parasitas em pacu . O paration metílico foi menos tóxico para os alevinos e para os juvenis de pacu do que a azadiractina, indicando a necessidade de cuidados com a utilização de extratos aquosos de neem no ambiente aquático. ACUTE TOXICITY OF THE INSECTICIDE METHYL PARATHION AND OF THE BIOPESTICIDE AZADIRACHTIN FROM NEEM LEAVES (Azadirachta indica) TO ALEVINE AND JUVENILE PACU (Piaractus mesopotamicus) Abstract The objectives of the present study were: to calculate the lethal concentration LC (I) 50-96 h of methyl parathion and of the biopesticide azadirachtin to alevine and juvenile pacu ( P. mesopotamicus). Also to determine the effect of body weight on acute toxicity of methyl parathion and of neem for pacu, as well as to classify the environmental risk of the methyl parathion and neem uses for the control of pacu parasites and pathogens. Two experiments were performed under laboratory conditions for the determination of the LC (I) 50-96 h. The LC (I) 50-96 h of methyl parathion was 3.97 mg/L for alevine and 9.89 mg/L for juvenile fish. The LC (I) 50-96 h of azadirachtin was 1.20 mg/L for alevine and 1.18 mg/L for juvenile pacu. Concentrations of 1.0 and 7.5 mg/L of methyl parathion and of 0.29 and 0.59 mg/L of azadirachtin for alevine and juvenile pacu, respectively, did not cause mortality in the exposed animals and can be used as references in studies on the control of parasites in pacu. Methyl parathion was less toxic to alevine and juvenile pacu than azadirachtin, indicating the need for careful utilization of aqueous neem extracts in aquatic environments.

Antibiotic resistance of the main infectious disease pathogens is one of the biggest problems of present time, which causes the need for searching for new antimicrobial medicinal substances and developing effective medicinal agents. One of the innovative medicinal preparations with the antimicrobial action, which is recommended for application for animals with hoof diseases, is ForticeptTM Hoof Oinment. Integration in the practice new medicinal preparations needs their strict toxicological control, which involves the exploring of acute and chronic toxicity and remote effects of possible side effect. The purpose of work was the determination of the acute toxicity parameters of the ForticeptTM Hoof Oinmentduring the oral administration to white laboratory mice and evaluation of the skin resorptive action of the preparation after it was administrated on rats’ skin. For determination of the acute toxicity there were used male laboratory mice with the average weight of the body 20 g – two groups with 10 animals in each. For the first group (the control one) with the help of the probe there was injected the distilled water (0.1 ml) into stomach. For the second group there was injected ForticeptTM Hoof Oinment (0.1 g), where the dose of the preparation is equal 500 mg/kg. For evaluation of the skin resorptive action of the preparation there were used 6 white rats with the average weight of the body 175 g. On the pre-prepared patch of skin there was administrated the preparation in the number that is equal 2857 mg/kg of body weight. For control there was leaved a free from preparation patch of bare skin. Exposition lasted for 4 hours. The indicators were explored in dynamics after 6, 24, 48 hours from the exposition started. After the research results there was established that ForticeptTM Hoof Oinment doesn’t cause death after its intragastric administration to the white laboratory mice in the number that is equal 5000 mg/kg of the body weight, that’s why depending on the degree of toxicity it belongs to the V toxicity class (Practically nontoxic). After one-time application of the preparation to the white rats in the number which is equal 2857 mg/kg of the body weight there wasn’t observes no death or pronounced changes in the behavior reactions, motor activity, state of the nervous system, amount of the consumed food and water. Therefore ForticeptTM Hoof Oinmentaccording to the results of the determination of the acute toxicity after its administration on the skin to the white rats depending on the degree of toxicity it belongs to the V toxicity class (Practically nontoxic). ForticeptTM Hoof Oinment doesn’t detect skin resorptive action, that points on the absence of toxic effects of the preparation due to its application on the skin.

Background and Aim: Global trend to remove the antibiotic growth promoter (AGP) from animals contributes to the exploration of successful measures to sustain production and reduces the intestinal diseases in the post-AGP era. Plant extracts, therefore, have been used to improve performance and intestinal health. Here, we conducted a study to evaluate the effects of neem (Azadirachta indica) leaf extracts (NLE) as alternatives to AGPs in broiler chickens. Materials and Methods: Sixty day-old broiler chicks were assigned to 12-floor pens, each stocked with five birds and divided into three treatment groups of four pens per treatment. The groups were: Negative control, basal diet without additives; positive control, basal diet with antibiotics and vitamins; and NLE treated group, basal diet supplemented with 0.1% aqua extract of neem leaves. Results: Overall feed intake was significantly (p≤0.05) highest in the positive control. Higher body weight, higher dressing percentage, and lower feed conversion ratio were observed in birds treated with NLE compared to the negative control group (p≤0.05) but not the positive control group (p>0.05). There was no significant variation in hematology between different groups. Furthermore, the economic evaluation indicated that the NLE treatment was found cheaper than control and antibiotic treatment in cost-benefit analysis. Conclusion: We suggest NLE might be a cheaper alternative to antibiotics in broiler production as indicated by improved body weight and feed efficiency.

Neem (Azadirachta Indica)is a plant that has been used as traditional medicine for a household remedy against various human ailments since ancient times. The objective of this study was to determine the phytoconstituents and antimicrobial activities of aqueous and methanol extracts of A. indica leaves. Qualitative and quantitative phytochemical analysis was carried out using the standard method of Association of Official Analytical Chemist and the antimicrobial activity of the concentrated extracts was evaluated by determination of the diameter of zone of inhibition against the microorganisms using the agar well diffusion method. Phytochemical screening of the leaves gave a positive result for saponins, tannins, steroids, glycoside, terpenoids, flavonoids, and alkaloids. The antimicrobial results show that both plant extracts had antimicrobial activity against the test organisms, the aqueous extracts were found to show the greater antimicrobial effect on Shigellasp (10.0±1.0 mm), Staphylococcus sp (10.0±1.0 mm), Penicilliumsp (9.2±0.8 mm) and Mould (10.2±1.3 mm) while methanol extract shows maximum efficacy on E. coli (26±1.0 mm), Vibrio sp (10.6±0.6 mm) and Yeast (9.2±0.3 mm). Therefore, these findings support the traditional knowledge of local users and it is a preliminary, scientific, validation for the use of neem leaves for the antimicrobial activity to promote proper conservation and sustainable use of the plant resources.

Background: Coccidiosis is recognized as the parasitic disease with the greatest economic impact on poultry industries worldwide. Sonali chicken are commonly affected by coccidiosis in Bangladesh. Recently, the concerns about possible drug resistance have aroused great caution in the usage of drug in the animal industry. As an alternative herbal extracts are used and Neem leaves (Azadirachta indica) have anti-coccidial property. This study was conducted to evaluate the comparative efficacy of Neem leaves suspension and toltrazuril on coccidial load, blood constituents, growth performance of Sonali chicken infected with Eimeria tenella. Methods: The study was conducted in the laboratory and experimental shed under the department of physiology and pharmacology, HSTU, Dinajpur during, 2nd January to 3rd February, 2019. Eighty (80) Sonali chicken of seven days old were randomly divided into four groups named T0, T1 T2 and T3 and each group contained 20 birds. All groups were supplied E. tenella orally except T0 group and after 3 days T2 group was treated with Neem leaves suspension (5%) for 15 days and T3 groups was treated with toltrazuril (topzuril ®) solution (1 ml/lit) for 2 days. Results: Results showed that protozoal load decreased significantly (P<0.01) in T2 & T3 groups whereas increased significantly (P<0.01) in T0 and T1 group. The total erythrocyte count and hemoglobin in different treatment groups were similar and the differences were non-significant (P>0.05) statistically except total leukocyte count (TLC). The body weight of T0, T1, T2 and T3 group at day 30 were 432.65, 469.81, 548.81, 489.22 gm respectively which is statistically significant (P<0.01) and highest body weight gain was recorded from Neem leaves suspension treated group. Conclusion: Neem leaves suspension have significant effects on protozoal load, body weight and no significant effect on haematological parameters except TLC.

The study of acute toxicity is a mandatory stage in the investigation of new drugs, which allows assessing the health of substances for health in the short-term and determining the class of toxicity and breadth of therapeutic action. Therefore, at the first stage of the study, the acute toxicity of Bendamin Cardiomatography was studied, in particular the determination of maximum tolerant, toxic and intermittent lethal doses for laboratory animals. The acute toxicity of Bendamin was determined in two stages: indicative and expanded experiments. In the indicative trial, the drug was administered intragastrically at doses of 50, 500 and 5000 mg/kg body weight. Three white mice and rats were used for each dose. In an expanded experiment, Bendamin was administered intragastrically at doses of 5000 and 10000 mg/kg body weight. In determining the acute toxicity of Bendamin, the DL50 value could not be determined, indicating a low toxicity of the test substance. Thus, the DL50 drug for intragastric administration to white mice is greater than 5000 mg/kg m. The general condition of animals in the studied groups did not differ from the state of intact animals: coordination of movements and skeletal muscle tone, pain response, tactile and acoustic stimuli were adequate, the frequency of breathing and the rhythm of heart rate were within the normal range. At administration of the preparation in a dose of 5000 mg/kg m. T, an insignificant inhibition was established, which is related to the introduction of a large amount of the drug. In determining the coefficients of the mass of the internal organs of laboratory animals, a slight decrease in the weight coefficient of the liver was found in both mice and in rats. The “Bendamin” drug when administered to white mice and rats in the stomach in the maximum amount does not cause symptoms of poisoning and behavioral abnormalities. According to GOST 12.1.007-76, Bendamin, for intragastric administration, according to the degree of hazard belongs to grade 4 toxicity – low toxicity substances (DL50 more than 10000 mg/kg body weight). In the future, it is planned to investigate the chronic toxicity and cumulative properties of the drug in laboratory animals.
