A life-time exposure study was conducted to assess the carcinogenicity of bromodichloromethane (BDCM) administered in the drinking water to male F344/N rats and B6C3F1 mice. In mouse, the calculated mean daily BDCM concentrations (measured concentrations corrected for on-cage loss of chemical) were 0.06, 0.28 and 0.49 g/l. Time-weighted water consumption of 135, 97, and 89 ml/kg/day resulted in mean daily doses of 8.1, 27.2, and 43.4 mg BDCM/kg/day. No changes in feed consumption, final body weight, or survival were observed. Kidney weights were significantly depressed at 27.2 and 43.4 mg BDCM/kg/day. There was no increase in neoplasia in the liver, kidney, spleen, testis, bladder, sections along the alimentary tract, excised lesions, or at any other organ site. In rat, the corrected mean daily BDCM concentrations were 0.06, 0.33, and 0.62 g/l. Time-weighted water consumption of 65, 63, and 59 ml/kg/day yielded 3.9, 20.6 and 36.3 mg BDCM/kg/day. No alterations in feed consumption, body weight gain, and survival were seen. Kidney weight was significantly depressed in the 36.3-mg/kg/day treatment group. There was a significantly enhanced prevalence and multiplicity of hepatocellular adenomas at 3.9 mg BDCM/kg/day (15.5% and 0.16/animal vs. 2.2% and 0.02/animal for the control). Hepatocellular carcinomas increased from 2.2% and 0.02/animal for the control and 3.9 mg BDCM/kg/day to 8.3% and 0.10/animal at 20.6 mg BDCM/kg/day. The combined neoplasms were enhanced at 3.9 and 20.6 mg BDCM/kg/day. Liver neoplasia was depressed to the control value at 36.3 mg BDCM/kg. The prevalence of basophilic and clear cell, but not eosinophilic cells, altered foci of cells declined with increasing dose. BDCM did not increase cancer in the large bowel, renal tubules, or in any of the other tissues examined. Renal tubular hyperplasia was observed at 36.3 mg BDCM/kg (15.8% vs. 8.7% for the control group). Under the conditions of the study, BDCM in the drinking water was not carcinogenic in the male B6C3F1 mouse, but was carcinogenic in the male F344/N rat based on an increased hepatocellular neoplasia.

To reduce broiler production cost, a study was carried out on utilisation of alternative, less costly feed components, namely kepok banana peel and corn hominy which were mixed and fermented using the fungus Rhizopus oryzae. The fermented substrate was added into commercial feed in order to determine its influence on the poultry’s production performance. This study employed a completely randomized design (CRD) with four treatments: one using 100% pure commercial feed, and the other three commercial feed mixed with the fermented feed component at the levels of 5%, 10% and 15%. All treatments were repeated four times during 25 days growth period. The results showed that supplementation of the fermented ingredient in the broiler ration at the levels of 5%, 10%, or 15% had no significant effect (P>0,05) on the feed consumption, body weight gain, feed conversion ratio, and the final body weight of the animals. Although mixing the fermented feed ingredient up to 15% in the commercial feed promoted the growth of the broilers, the results were not yet comparable to pure commercial feed.Keywords: Corn hominy, broiler, fermentation, kepok banana peel, Rhizopus oryzae AbstrakUntuk mengurangi biaya produksi ayam pedaging, dilakukan pengkajian penggunaan bahan penyusun pakan alternatif yang lebih murah, yaitu kulit pisang kepok dan ampok jagung yang dicampur dan difermentasi menggunakan jamur Rhizopus oryzae. Hasil fermentasi tersebut lalu ditambahkan pada pakan komersial ayam pedaging dengan tujuan mengetahui pengaruhnya terhadap penampilan produksi ayam pedaging. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan, yaitu satu perlakuan 100% pakan komersial murni, dan tiga perlakuan pakan komersial yang dicampur bahan pakan hasil fermentasi tersebut dengan kadar 5%, 10%, dan 15%. Seluruh perlakukan diulang empat kali selama 25 hari masa pemeliharaan. Hasil penelitian menunjukkan bahwa penambahan bahan pakan terfermentasi ke dalam ransum ayam pedaging pada kadar 5%, 10%, atau 15% tidak memberikan pengaruh nyata (P>0,05) terhadap konsumsi pakan, pertambahan bobot badan, nilai koversi pakan, dan bobot badan akhir hewan. Meskipun penambahan bahan pakan fermentasi tersebut hingga 15% dalam pakan komersial mendukung pertumbuhan ayam pedaging, namun capaian pertumbuhannya belumlah sebaik pakan komersial.Kata kunci: Ampok jagung, ayam pedaging, fermentasi, kulit pisang kepok, Rhizopus oryzae

The present study was conducted to evaluate the effect of different levels of methionine supplementation on feed intake, nutrient digestibility and growth performance of growing rabbit. Sixteen weaned crossbred New Zealand White (NZW) growing rabbits (30-35 d) were distributed into four treatment groups having four replications in each group using a Completely Randomized Design (CRD). Basal diet composed of green grass (dhal grass) and concentrate mixture which was offered ad libitum basis for 56 days period. Four levels of methionine such as 0.0% (control), 0.15%, 0.25%, and 0.35% were supplemented randomly to rabbits. Results showed that supplementation of methionine did not affect green grass intake. Cumulative as well as daily concentrate and DM intake were significantly (p<0.05) higher for all methionine groups than control group. Final body weight gain as well as daily, weekly and cumulative body weight gains were improved significantly with increasing level of methionine. It was found that methionine had significant (p<0.01) effect on digestibility of DM, CP, NFE and EE but CF digestibility did not differ significantly. Digestibility was improved with increasing the level of methionine. Feed conversion ratio also decreased significantly with methionine supplementation, and 0.25% methionine group showed the best performance among the four treatments.

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.

ABSTRACT. The aim of this experiment is to investigate a possibility to include tofu by-product in broiler diet without causing adverse performances. This study was conducted in poulty production Lab. Faculty of Agriculture, Syiah Kuala University, Banda Aceh. The study performed 80 unsex day old chick, strain CP 707, Charoen Pokphan product, for which the chikens were divided into for diet treatment. The study was desingned into Completely Randomized Design (CRD) containing for different diet treatment. ei. R1 (Control diet with 0% of tofu by product. R2 (the diet containing 2.5% of tofu by-product), R3 (the diet containing 5% of tofu by-product, and R4 (the diet containing 7.5% of tofu by-product). Each treatment consisted of five chiks. Investigated variables included  final body weight, body weght gain, feed consumption, feed conversion, and income over feed and chick coast (IOFCC). The data were analyzed by an analysis of variance and as a significant effect was detected, the analysis  was continued by Duncan Multiple Range Test based on Steel and Torrie (1991). Result of this study showed that the inclusion of up to 5% of tofu by-product in the diet were not significantly defress body weight, body weight gain, feed consumpsion, and feed conversion compared to the control. However, the inclusion of 7.5% of tofu by-product significantly defress body weght, body weight gain feed consumpsion. The was no significant effect on feed conversion as tofu by-product was included 7.5% in the diet. The inclusion of tofu by-product could minmize diet cost and increase. Income and Over Feed and Chick Cost (IOFCC). However, the highest IOFCC was detected in the untilization of 5% of tofu by-product was still possible to be included in poulty diet up to 5% without significantly depress broiler ferformances.Key word :Tofu by-product; Broiler diet; Body weight; Feed Consumption; Feed conversion

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.
