Background: Nowadays poultry industry, an important sector is becoming a serious threat to public health due to the heavy metal exposure & accumulation in poultry tissues. Therefore, our recent study was aimed to investigate the toxic effects of lead (Pb) exposure in broiler chicken. Methods: A total number of 72 broiler chicks (Cobb-500, 12th day old) were assigned to four dietary treatments with three replicates. Control group received only basal diet without any supplementation. The other groups T1, T2 and T3 received feed with supplemented Pb @ 10, 30 and 50mg/kg feed, respectively. The body weight of each bird was weighed at 3 days interval. Results: Lead caused elevation of SGPT/ALT (P<0.01) and decreased serum creatinine attributed to pathological lesions including enlarged, pale & friable liver, swollen kidneys and splenomegaly in experimental groups. On histopathological examination, liver shows cirrhosis and necrosis in all treated groups. In the kidney, glomerulus was filled with reactive cells in group T1 while fibrosis and necrosis were found in groups T2 & T3. Conclusions: Lead toxicity in broiler had a dose-dependent effect on body weight gain, blood parameters, gross and histological changes.

The study was conducted to determine the efficacy of organic Se produced through Saccharomyces cerevisiae from sodium selenite in the diet of Vanaraja and commercial broiler chicken. The trial was conducted in day-old Vanaraja chicks (n=160), which were randomly distributed into 4 dietary groups having 5 chicks in each of 8 replicates. The basal diet (BD) was formulated and supplemented with calculated quantity of organic Se to formulate the different experimental diets and fed up to 5 weeks. The second experiment in day-old commercial broiler chicks (n=350), which were randomly distributed into 7 dietary groups having 5 chicks in each of 10 replicates. The experimental birds were fed BD (diet I) with 0.2 mg/kg organic Se (diet II), 0.4 mg/kg organic Se (diet III) and 0.6 mg/kg organic Se (diet IV), and BD with 0.2 mg/kg inorganic Se (diet V), 0.4 mg/kg inorganic Se (diet VI) and 0.6 mg/kg inorganic Se (diet VII) up to 6 weeks. The body weight gain during 5th week was higher (P Lass Than 0.05) in the birds fed with diet supplemented 0.3 mg/kg of the organic Se compared to the other groups. However, feed intake and feed conversion ratio (FCR) among different groups did not vary (P>0.05) throughout the experiment. The activity of glutathione peroxidase was higher (P Lass Than 0.01) among the groups fed the diets containing organic Se (0.2, 0.3 and 0.4 mg/kg) compared to the control diet in experiment I. In experiment II, body weight gain and FCR at the end of the experiment were improved significantly (P Lass Than 0.01) in the group fed 0.2 mg/kg organic Se compared to control. Alanine transaminase, Aspartate aminotransferase, triglycerides and cholesterol levels were lower in groups fed diets supplemented organic Se compared to control or inorganic Se fed groups. Whereas, glutathione reductase activity was significantly higher among the groups supplemented organic Se compared to other dietary groups. Based on the results it can be concluded that supplementing organic Se up to 0.3 mg/kg enhanced the body weight gain and anti-oxidant enzyme activity in Vanaraja and commercial broiler chicken.

Previously, we have found that the addition of L-ascorbic acid to chitosan enhanced the reduction in body weight gain in guinea pigs fed a high-fat diet. We hypothesized that the addition of L-ascorbic acid to chitosan would accelerate the reduction of body weight in humans, similar to the animal model. Overweight subjects administered chitosan with or without L-ascorbic acid for 8 weeks, were assigned to three groups: Control group (N = 26, placebo, vehicle only), Chito group (N = 27, 3 g/day chitosan), and Chito-vita group (N = 27, 3 g/day chitosan plus 2 g/day L-ascorbic acid). The body weights and body mass index (BMI) of the Chito and Chito-vita groups decreased significantly (p < 0.05) compared to the Control group. The BMI of the Chito-vita group decreased significantly compared to the Chito group (Chito: -1.0 kg/m2 vs. Chito-vita: -1.6 kg/m2, p < 0.05). The results showed that the chitosan enhanced reduction of body weight and BMI was accentuated by the addition of L-ascorbic acid. The fat mass, percentage body fat, body circumference, and skinfold thickness in the Chito and Chito-vita groups decreased more than the Control group; however, these parameters were not significantly different between the three groups. Chitosan combined with L-ascorbic acid may be useful for controlling body weight.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

Abstract Background The aim of this study is to investigate whether the energy matrix values of the nonstarch polysaccharide- (NSP-) degrading enzymes, bioemulsifier (LYSOFORTE®), guanidinoacetic acid (CreAMINO®), or their combinations could be summed. The effects of these additives on the growth performance, carcass traits, and economic value of the broiler chicken diets were evaluated. A total of 525-one-day-old Ross chicks with an initial body weight of 42.96 ± 0.87 g were haphazardly allocated into seven groups with five replicates. The seven experimental treatments are as follows: (1) basal diet with no additives (breeder recommendation), which is the control group, (2) basal diet minus 100 kcal/kg supplemented with 0.02% NSP-degrading enzymes (NSP), (3) basal diet minus 50 kcal/kg supplemented with 0.025% emulsifier (LYSOFORTE®), (4) basal diet minus 50 kcal/kg supplemented with 0.06% guanidinoacetic acid (CreAMINO®), (5) basal diet minus 150 kcal/kg supplemented with a mixture of NSP and LYSOFORTE® (NSPL), (6) basal diet minus 100 kcal/kg supplemented with a mixture of NSP and CreAMINO® (NSPC), and (7) basal diet minus 200 kcal/kg supplemented with a mixture of NSP, LYSO, and CreAMINO® (NSPLC). The experiment lasted for 35 days. Results It was found that the final body weight, body weight gain, and relative growth rate were significantly higher in birds fed diets supplemented with NSPL, NSPC, CreAMINO, and LYSO with the reduced energy matrix value. The overall feed conversion ratio was significantly improved due to the supplementation of NSPC, CreAMINO, NSPL, and LYSO with the reduced energy matrix value compared to the control group. Moreover, no significant effect on the carcass criteria was observed by the different treatments. As a result of the dietary supplementation with NSPL, NSPC, CreAMINO®, and LYSO with the reduced energy matrix value, the net profit, total return, economic efficiency, and performance index were increased and the cost of feed per kg of body weight gain was decreased. Conclusion The energy matrix value of NSPL, NSPC, CreAMINO®, and LYSOFORTE could be established in the diets of broiler chickens to improve the growth performance and economic efficiency.

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.

Two trials were conducted on floor pens to evaluate the performance of broilers fed with diets contained different carbohydrases enzyme programs at different ages. Trial 1- The body weight gain (BWG) was affected by the Negative Control (NC) treatment (P<0.05). However, when the birds were fed with the NC diet + Amilase (AMY)+Xilanase (XYL), the BWG improved and reached the same level as the Positive Control (PC). Trial 2- The birds received enzymes supplementation in the total phase and others only in the grower phase.The ME reduction by 120 kcal/kg increased the feed conversion ratio (FCR) (P<0.05) when compared to PC and none of the enzyme programs was able to recover the performance. It can be concluded that it is possible to supplement with AMY during the role period of broiler chicken life or use an enzymatic program with AMY or AMY+XYL only in the grower phase.

This study was conducted to observe the effect of different administration method of garlic and neem on growth performances, feed efficiency and serum biochemical parameters for safe broiler production. The experiment was done for a period of 32 days with 384 one-day-old straight run broiler chicks. The broiler chicks were divided into six groups each of 64 birds and replicated to four subgroups each of 16 birds. The dietary groups were; control (basal diet; no additives), antibiotic (basal diet + antibiotic), garlic in feed (basal diet + 0.25% garlic powder), garlic in water (basal diet + garlic extracts), neem in feed (basal diet + 0.25% neem powder) and neem in water (basal diet + neem extracts). Results showed that the body weight and body weight gain increased significantly (P<0.05) in both the garlic and neem groups compared to the control group. Feed intake was not different (P>0.05) among the treatment groups. Garlic in feed and water and neem in feed groups showed better FCR (P<0.05) compared to the other treatment groups. There were no significant (P>0.05) difference in meat yield, bone development and dressing parameters except head and gizzard in different dietary groups. Supplementation of garlic with feed and water significantly (P<0.05) decrease cholesterol, triglyceride and LDL compared to the other groups. However, both the garlic and neem groups showed numerically higher HDL compare to the control group. There were no 0significant (P>0.05) differences in serum glucose and GPT among different treatment groups. GOT was significantly (P<0.05) lower in neem groups than that of garlic and antibiotic groups. Additive groups showed higher profitability than control group. Based on the results of the study, it may be suggested that the garlic and neem could be used both in feed and water as potential feed additives for safe broiler production. Bang. J. Anim.

A trial was conducted with 32 indigenous goat kids (Capra prisca) 8,5 weeks old to examine the effectiveness of dietary avoparcin as growth promoting factor. The kids were randomly allocated into two groups (control- and avoparcin group with initial mean body weight of 11,61 ±1,16 kg and 11,57±1,47 kg, respectively) comprising of 16 kids (8 male and 8 female) each. For a period of 12 weeks, kids in the control group were given lucerne (alfalfa) hay (mean daily consumption 170 g/head) and an appropriate compound diet (given ad libitum), while kids in the avoparcin group were fed the same diet except that the compound diet was supplemented with avoparcin (20 mg/kg). Avoparcin supplementation significantly (P<0.05) improved final mean body weight by 10.57% (19.24 ± 2.33 kg vs. 17.40 ± 2.30 kg), body weight gain (BWG) by 32.30% (7.66 ± 1.42 kg vs. 5.79 ± 1.74 kg), mean daily feed consumption in dry matter basis (DM) by 14.24% (551.80 ± 31.60 g DM vs. 483.02 ± 28.94 g DM), feed conversion ratio by 13.62% (6.09 ± 0.47 kg DM consumption/kg BWG vs. 7.05 ± 0.56 kg DM consumption/kg BWG) and carcass weight by 14.86% (11.44 ± 1.48 kg vs. 9.96 ± 1.76 kg). Moreover, no significant differences (P>0.05) were noticed neither in carcass yield and carcass chemical composition nor in percentages of small intestine-, major omentum-, lung-,heart-, liver- and spleen weight in the body weight.

O Manganês (Mn) é um metal essencial para o organismo. É distribuído no ambiente e utilizado em processos industriais. Apesar de essencial, é neurotóxico à exposições cumulativas, causando uma desordem neurológica, o Manganismo. O estudo avaliou o efeito da administração subaguda de Mn sob a forma de cloreto e acetato de Mn, sobre a função mitocondrial e parâmetros oxidativos no encéfalo, bem como o acúmulo deste metal no encéfalo e tecidos periféricos de ratos adultos. Os ratos receberam 6 mg/kg de Mn i.p. na forma de cloreto ou acetato de Mn, 5 dias/semana por 4 semanas. O grupo controle recebeu solução salina 0,9% pela mesma via de administração e mesmo período. Foi mensurada a concentração de substâncias reativas ao ácido tiobarbitúrico (TBARS) e grupamentos NPSH, a atividade dos complexos I e II da cadeia respiratória no encéfalo e/ou estruturas cerebrais, bem como o peso corporal e a concentração de Mn e Fe no soro, encéfalo, tecido renal e hepático. Foi observada uma diminuição no ganho de peso corporal dos animais que receberam o Mn, um aumento na concentração/depósito de Mn no soro, encéfalo e tecido renal, tanto na forma de cloreto e acetato de Mn, quando comparados com o grupo controle. Além disso, houve um aumento significativo no conteúdo de NPSH no encéfalo e, embora não significativo, uma tendência de aumento da concentração de TBARS, no grupo que recebeu cloreto de Mn. Ainda, foi verificada uma inibição na atividade do complexo I no estriado dos animais expostos ao cloreto de Mn. Não houve diferença entre os grupos nas atividades do complexo I e II no encéfalo e hipocampo. Em conjunto, os dados indicam que a exposição ao Mn em baixas doses contribui para o desenvolvimento de estresse oxidativo e disfunção mitocondrial no SNC, com aparente predileção de dano ao estriado.Palavras-chave: Manganês. Exposição subaguda. Parâmetros oxidativos.

It is distributed in the environment and used in industrial processes. Although essential, it is neurotoxic to cumulative exposures, and can cause a neurological disorder, called Manganism. This study evaluated the effect of subacute Mn as chloride and acetate of Mn administration on mitochondrial function and oxidative parameters in adult rat brain, as well as the accumulation of this metal in the brain and peripheral tissues. The rats received 6 mg/kg of Mn i.p., as Mn chloride or Mn acetate, 5 days/week for 4 weeks. The control group received 0.9% of saline solution in the same way of administration and in the same period. It was measured the concentration of thiobarbituric acid reactive substances (TBARS) and NPSH groups, the activity of mitochondrial complex I and II in brain and/or in the brain structures, as well as the body weight and the concentration of Mn and Fe accumulation. It was observed a decrease on body weight gain in animals exposed to Mn and an increase of concentration/deposit of Mn in serum, brain and kidney, in the both Mn chloride and acetate form when compared to the control group. In addition, there was a significant increase in brain NPSH content and, although it was not significant, a trend of increasing on TBARS concentration in the group that received Mn. Besides that, a significant inhibition of complex I activity was observed in the striatum of the animals exposed to Mn. There was not difference between groups on complex I and II in the brain and hippocampus. Together, these data indicate that exposure to Mn at low doses contributes to the development of oxidative stress and mitochondrial dysfunction in the CNS, with apparent predilection of striatum damage.Keywords: Manganese. Subacute exposure. Oxidative parameters. Mitochondrial function.
