Broiler chicks, allocated in a randomized block design, were fed four diets containing ethylene diamine tetraacetic acid (EDTA) at 0, 0.1, 0.2 and 0.4% of the diet and drinking water with a high salt concentration (6000 ppm). A control group received tap water and the EDTA-free diet. The addition of 6000 ppm NaCl in the drinking water had no effect on weight gain or feed conversion. Similarly, the inclusion of up to 0.4% EDTA in the feed had no adverse effect on weight gain. Analyses of packed-cell volume (PCV) and plasma sodium, chloride and calcium concentrations showed no changes as a result of treatment. Water consumption almost doubled for the chicks subjected to high salt water regimens compared with the control. Two groups of chicks received the EDTA-free diet, and significantly (P < 0.10) higher mortality was found for the group on the salt water compared with the tap water controls. The mortality in the former was also significantly (P < 0.10) higher than for the group receiving 0.2% EDTA in the diet and salt water. The chicks on the 0.4% EDTA diet had significantly (P < 0.05) higher mortality than control chicks on tap water and those chicks receiving salt water and diets containing 0.1% and 0.2% EDTA. Postmortem examination indicated that ascites and widespread edema were the causes of death in chicks that drank salt water and consumed diets containing no EDTA or 0.4% EDTA. The death of chicks on treatments that resulted in low mortality rates was not attributable to ascites. The reason for the apparent beneficial effect of feeding 0.2% EDTA in the diet in conjunction with the salt water remains open to conjecture.

Group I

To determine whether salt loading increases the sensitivity of the myocardium to fatal arrhythmias induced by norepinephrine, four groups of Sprague–Dawley rats were studied. Group I received both saline (0.9%) as drinking water and deoxycorticosterone acetate (DOCA) (0.5 mg/kg, 3 times) for 14 days (DOCA high salt group); group II received only 0.9% saline as drinking water (high salt group); group III received DOCA in the same dose regime, but tap water to drink (DOCA group); and group IV received tap water (control). Under pentobarbital anesthesia, norepinephrine was infused and electrocardiogram and blood pressure were monitored. The DOCA high salt group developed arrhythmias significantly (p < 0.05) earlier than at lower norepinephrine doses. The dose at which 50% mortality occurred was 20 μg∙kg−1∙min−1 in DOCA high salt group, 37 μg∙kg−1∙min−1 in high salt group, 40 μg∙kg−1∙min−1 in the control, and 44 μg∙kg−1∙min−1 in the DOCA group. The cumulative dose of norepinephrine associated with 50% mortality was 160 μg/kg in the DOCA high salt group, 370 μg/kg in the high salt group, 530 μg/kg in the control group, and 600 μg/kg in the DOCA group. The blood pressure after sodium loading before norepinephrine infusion was similar in all three groups. The blood pressure response to norepinephrine was not significantly different between the four groups. Myocardial content of the electrolytes Na+, K+, Mg2+, and Ca2+, were not significantly different between three of the groups, namely those receiving DOCA plus high salt, high salt or neither DOCA nor high salt as ascertained in other animals who were treated according the the three protocols. These data suggest that excess dietary sodium enhances the sensitivity to norepinephrine-induced cardiac arrhythmias.

An experiment was conducted to determine the influence of an acidifier as an alternative to antibiotics on the performance and gut morphology of broiler chickens. One hundred and eighty (180) 7-day old broiler chicks were randomly assigned to 3 dietary treatments of 4 replicates each. Each replicate had 15 birds. The diets fed to the birds were: Treatment 1- diet with neither antibiotic nor acidifier; Treatment 2- diet with antibiotic and Treatment 3- diet with acidifier. The antibiotic used was Enrofloxacin which was administered to the birds on Treatment 2 via their drinking water while the acidifier used was Biotronic SE (a combination of propionic and formic acids) which was added to the diet of birds on Treatment 3 at the rate of 4kg/tonne of feed. The experiment lasted 42 days. No significant differences were observed in the feed intake, final weight and weight gain of the birds on the different diets. Significant differences were however observed in the villus height in the duodenum and ileum of the birds. The crypt depth values in the different segments of the small intestines of the birds were not significantly affected by the different treatments.Key words: Organic acids, Biotronic SE, Enrofloxacin, Crypt, villus.

Phyllanthus niruri L. (Euphorbiaceae), known as "quebra-pedra" (Portuguese for "stonebreaker"), is an herb used for kidney disorders. In light of its frequent use by the population, the present study aimed to investigate the genotoxic, antigenotoxic and cytotoxic activities of a standardized P. niruri extract in bone marrow rats. Three groups of 12 animals were treated daily by gavage over a period of 30 days, with 50, 150 or 250 mg/kg of P. niruri extract aqueous solution. The control group (n = 12) received tap water. At the end of treatment (day 31), groups were divided into two minor subgroups (n=6/group) and received cyclophosphamide (50 mg/kg, i.p.) or saline 0.9% (i.p.). After 24 hours, we evaluated the frequency of micronucleated polychromatic erythrocytes for each animal (MNPCE) at 1000 PCE. Cytotoxicity was evaluated with the PCE/NCE ratio (NEC = normochromatic erythrocytes). General toxicity was assessed during treatment using the parameters of body weight gain, ration and water consumption. The dry extract did not provoke changes in body weight, weight gain, ration and water intake or changes in the frequency of MNPCE or cytotoxicity in bone marrow. We propose that the P. niruri extract used here showed no genotoxic, antigenotoxic and cytotoxic activities under the experimental conditions.

The efficacy of tulsi (Ocimum sactum) and neem (Azadirachta indica) leaves extract as a growth promoter were studied in broiler. A total of 40 day-old broiler chicks were purchased from Kazi hatchery and after three days of acclimatization the chicks were randomly divided into four groups (n=10). No vaccination schedule was practiced and no antibiotic was added in ration of group A, B, C, and D respectively. Group A served control without any supplements while group B, C and D were supplemented with combination of tulsi and neem extract @ 1 ml, 2ml and 3 ml/liter of drinking water. Live body weight gain was recorded weekly up to 6th weeks and hematological studies were performed at 21st and 42nd day of experiments. At the end of 42nd day of experiment final body weight of group A, B, C and D were 1561± 12.10 g, 1698± 12.87 g, 1608± 12.04 g and 1763± 13.28 g, respectively. The birds of group D utilized their feed more efficiently among the treatment groups (p<0.05). The net body weight gain were, 1533± 11.98 g, 1443± 11.32 g and 1588± 12.10 g in treated groups compared to control group (1393± 11.07 g ) and total net profit per broiler was 19.08, 40.10, 20.68 and 45.07 Taka , respectively. Hematological parameterss (TEC, PCV, Hb and ESR) were not significantly changed among the treated and control group suggesting no side effects of herbal extracts in broiler. It can be concluded that tulsi and neem extract is economic and safe in broiler production.DOI: http://dx.doi.org/10.3329/bjvm.v11i1.17728 Bangl. J. Vet. Med. (2013). 11 (1): 1- 5

This study was conducted under the Department of Physiology and Pharmacology to determine the effects of Neem and Nishyinda leaves supplementation on growth performance and GUT biosis in broilers. A total of 40 day old broiler chicks were divided into four groups A, B, C and D. Group A was considered as control, fed only with commercial broiler ration. Group B supplemented with formulation of 2 gm grinded Neem leaves, Group C with 2 gm grinded Nishyinda leaves and Group D with 1 gm grinded Neem leaves plus 1 gm grinded Nishyinda leaves per liter of water respectively. Observations were recorded for live body weight, weight gain, feed consumption, feed efficiency, hemato-biochemical parameters and GUT biosis specially the parasite of birds in six weeks. Body weights were increased significantly (p<0.05) in all treated groups in respect to the control and highest was recorded in combine Neem plus Nishyinda supplemented groups (Group D). No significant (p>0.05) differences were observed among the groups for PCV and TEC values. Hb content increased and ESR decreased significantly (p<0.05) with combine Neem plus Nishyinda supplemented group (Group D). The serum SGOT and SGPT levels were also decreased with the same kind of supplementation. In treatment group there was significantly decreased of parasitic eggs, but in case of control group no decrease of parasitic eggs. There was no significant pathological change in any internal organs of the broiler of treated groups. Best result was found in the group D. The present study reveals that combine supplementation of Neem plus Nishyinda gives better result over other groups in respect to body weight gain, feed conversion ratio, hemato-biochemical parameter and profitability without making any health hazard of the broilers.

This study was conducted to determine the effects of dietary supplementation of peppermint ( Mentha piperita L.) on the performance of broiler chicks. 500 Ross broiler chicks were divided into 5 treatment groups of 4 replications in a completely randomized design format. The diets were ISO-caloric and ISO-nitrogenous ones and contained 1.5, 3, 4.5, and 6 g/kg of peppermint powder. At start, growing, and end periods, the effects of peppermint powder on average daily weight gain, feed conversation ratio, and mortality rate were studied. The results of the present study showed that over a production period of 42 days peppermint had a significant effect on average daily weight gain and feed conversation ratio when compared with the control group ( P < .05). The level of 4.5 g/kg had the highest average daily weight gain (52.78 g), and control treatment with 46.98 g had the least average daily weight gain among different levels of peppermint. The level of 4.5 g/kg and 6 g/kg of peppermint had the least mortality compared to control treatment during training period ( P < .05). From this experiment, we can conclude that treatment with 4.5 g/kg peppermint powder has better performance and carcass characteristics in broilers.

Six groups, each of six sheep, were fed in pens for 15 months on a ration of chaffed lucerne and wheaten hays. One group was offered rain-water to drink, another group was offered 1.30% sodium chloride, whereas the others were offered one of the following mixtures of sodium chloride, carbonate, and bicarbonate: 1.26 + 0.015 + 0.025, 1.21 + 0.04 + 0.06, 1.12 + 0.08 + 0.13, and 0.95 + 0.161+ 0.25%. The intake of all saline solutions was higher than that of rain-water, ranging from 150% above for 1.30% sodium chloride to 60% above for the highest level of carbonates; the mean daily intakes for the entire experiment by the six groups were 2.6, 6.6, 4.8, 5.7, 5.8, and 4.2 l. respectively. The intake also increased in all groups with temperature, being 40–70% higher in the hottest months than in the coldest months.Weight increase was less from 6 months onward in the group receiving 1.30% sodium chloride, and was less at certain times only in the experiment in the groups receiving 0.04 or 0.10% carbonates, than in that receiving rain-water (control group). There were no differences in weight increase between the control group and the groups receiving the highest concentrations (0.21 and 0.41%) of carbonates The saline drinking waters had no effect on the concentrations of sodium, potassium, calcium, magnesium, or chloride in the blood plasma. The concentration of carbon dioxide was higher, for the last year of the experiment, in the blood of the control group, and, for approximately one-third of the experiment, in that of the group receiving the highest level of carbonates in its drinking water, than in that of any of the groups receiving lower levels of carbonates. There were differences in blood carbon dioxide on one occasion only between the control group and that receiving the highest level of carbonates. None of the solutions used in the experiment had any adverse effect on the general health, food consumption or wool production of the sheep.

The influence of sodium chloride ingestion via the drinking water upon the flux of fluid and minerals to and from the rumen of sheep has been examined. Four Merino wethers were each prepared with ruminal and bilateral parotid duct fistulas to allow continuous sampling and measurement of flow rates and were offered rainwater which was zero, 136 or 221mM with respect to sodium chloride as the only source of drinking fluid. Parotid salivary flow rate decreased by up to 43% when the saline concentration of the drinking water was increased. There was an inverse relationship between saliva flow rate and the fluid intake, but much of the effect appeared to be due to ingestion of sodium chloride per se. Salt water ingestion caused an increase in the salivary concentration of sodium and phosphate; a decrease in that of potassium; and no change in that of chloride or osmolality. The rate of secretion of sodium varied directly with saliva flow rate. The outflow of water from the rumen to the omasum, or its net absorption across the rumen wall, were not influenced by treatment. In centrifuged rumen fluid samples saline ingestion caused increased levels of sodium, chloride and osmolality; decreased levels of potassium; and no change in calcium, magnesium or phosphate. Outflows of sodium and chloride to the omasum were increased. The apparent absorption of sodium and chloride from the rumen increased proportionately to the inflows of these ions via the saliva and drinking fluid. The additional sodium and chloride ions arising from the ingested saline were absorbed in approximately equal amounts. Saline drinking by sheep leads to a reduction in the rate of secretion of parotid saliva and its accompanying ions, which partially compensates for the added amount of fluid and electrolyte which enter the rumen in the drinking water.

Background and Aim: Wood vinegar is a product generated from the combustion and distillation of wood and other plant materials. It has been shown to suppress bacteria, resulting in healthier livestock and increased yields. This study aimed to determine the efficacy of drinking water supplemented with wood vinegar on growth performance, intestinal health, and gut microbial of broilers. Materials and Methods: A total of 120 Ross 308 1-day-old male broiler chicks were randomly distributed in a completely randomized experimental design. The study consisted of three treatments containing four replicates, with 10 birds in each. Treatments were given 0.5% and 1.0% (V/V) wood vinegar supplemented in drinking water, while no supplementation was given to the control group. The animals were raised in an open-house system. All groups were provided with a commercial diet and drinking water ad libitum. Analysis of variance was conducted using the general linear model procedure to compare the levels of wood vinegar supplementation in drinking water on growth performance, intestinal morphology, and gut microbial. Results: No significant differences (p>0.05) were found for body weight gain, feed intake, feed conversion ratio, and water consumption between groups during the starter (1-21 days old), grower (22-35 days old), and whole (1-35 days old) growth periods. Moreover, no significant differences in villi height and crypt depth (p>0.05) at 21 and 35 days of age were found. In addition, no significant difference in terms of lactic acid bacteria and Escherichia coli was found between the different treatments. Conclusion: Drinking water supplemented with wood vinegar was not found to have an effect on the growth performance and gut microbial of broiler chickens in the present study. However, the supplementation of wood vinegar in drinking water could improve intestinal morphology.

Cadmium (Cd) is considered to be one of the major environmental pollutants which have potential threat to human health. Reports of declining male fertility have renewed interest in the role of environmental and occupational exposures in the etiology of human infertility. Cd exposure led to obvious degenerative changes in testicular tissue. This study was performed to investigate the Cd-induced structural effects on the testes and to evaluate the possible protective effect of omega-3 oil in adult albino rats. Thirty adult male rats were used in the present work, divided randomly into five groups, six rats in each group; the first group was considered as a control group and left without treatment except the standard rat chow and tap water. The second group was given 40 mg/L of CdCl2 in drinking water while the third group was given 60 mg/L of CdCl2 in drinking water. The fourth group was given 40 mg/L of CdCl2 in drinking water plus omega-3 oil (4 g/kg diet), while the fifth group was given 60 mg/L of CdCl2 in drinking water plus omega-3 oil (4 g/kg diet), the Cd-treated rats showed dose-dependent histological and ultrastructural alterations which have been ameliorated after exposure to omega-3 oil. The present investigation concluded that omega-3 played a protective role against Cd-induced histopathological changes in rat testis.
