  An investigation was made on the performance of 144 unsexed Van Cobb broiler chicks from 21 days to 42 days of age. The chicks were fed on soybean meal (SM) based iso-nitrogenous and iso-energetic diet incorporating phytase with the levels of 0.0, 0.50, 1.00 and 1.50 g/kg diet for better utilization of the basal diet. The growth rate, feed intake, feed consumption, dressing yield and profitability increased as the level of phytase supplementation increased and the level of phytase had no effect on survivability. The addition of phytase seemed to be effective to overcome the antinutritive effect of phytate phosphorus and non-starch polysaccharides (NSP) on broiler performance. Therefore, it was concluded that 1.50 g/kg phytase may be incorporated in SM based broiler diet for profitable production.

  A study to determine the seroprevalence of brucellosis in local chickens in Sokoto State of Northwestern Nigeria was carried out. A total of one thousand serum samples were collected over a period of six months. The serum samples were subjected to Rose Bengal Plate test, serum agglutination test (SAT), Elisa (Compelisa) using both Brucella arbortus and B. melitensis antigens. Results indicated that 30 (3.0%) 28 (2.8%) and 26 (2.6%) were positive for melitensis using compelisa and RBPT while 24 (2.4%) for SAT. It is recommended that rearing method employed where cattle, sheep and other animals are housed together with chickens should be discouraged. Public education and enlightenment campaign to poultry owners and handlers on the dangers of brucellosis should be intensified and future surveillance and control programmes on brucellosis should include local poultry.

  In Bangladesh, about 100 pharmaceutical companies are manufacturing about 160 products of metronidazole. Of them 40 products (30 tablet and 10 suspension) were analyzed. Potency of the selected products were assayed spectrophotometrically and their various physical parameters (color variation, thickness, weight variation, hardness, friability, disintegration time, dissolution rate, pH of suspension) were analyzed according to the official (BP/USP) pharmacopoeial methods to evaluate their quality. The results showed that 26 brands of tablets meet the BP specification of potency and the remaining 4 were less potent. 8 brands of suspensions meet the BP specification of potency and the remaining 2 were less potent. All brands tested, showed a good result for color variation, thickness, hardness, disintegration time and dissolution rate. 2 brands failed to meet the weight variation test specification. It is evident from the study that most of the brands tested showed good results but a few of them failed to meet the specification.

  The ethanol extract of leaves of Hoya parasitica was tested for its phytochemical groups, antibacterial and antinociceptive activities. The ethanol extract showed the presence of flavonoids, reducing sugars, tannins, gums and saponins. The extract showed moderate antibacterial activity against both gram-positive and gram-negative bacteria. It also produced significant (p<0.01) writhing inhibition in Swiss albino mice at oral dose of 500 mg kg-1 body weight comparable to the standard drug diclofenac sodium.

  The experiment was conducted with three nitrogen levels (N1-50 kg N ha –1, N2-75 kg N ha–1, N3-100 kg N ha–1) and four times of leaf cutting (C0-no cutting, C1-cutting at 21 DAT-Day After Transplanting, C2-cutting at 35 DAT and C3-cutting at 49 DAT) to find the possibility of production of rice for green fodder as well as seed. Nitrogen levels exhibited their difference in almost all crop characters. The plant height, number of total tillers hill–1, green forage, forage dry matter, cumulative straw yield, number of productive tillers hill–1, number of non-bearing tillers hill–1, number of total spikelets panicle–1, number of grains panicle–1, number of sterile spikelets panicle–1, grain yield and straw yield were found to be highest with the highest level of nitrogen. Panicle length and 1000-grain weight did not vary with nitrogen levels. The values of these characters were found to be lowest with the lowest level of nitrogen (50 kg N ha–1). Harvest index was the highest at moderate level of nitrogen (75 kg N ha–1). Time of leaf cutting had significant influence on all the parameter studied. Plant height, number of total tillers hill–1, cumulative straw yield, number of productive tillers hill–1, number of non-bearing tillers hill–1, number of total spikelets panicle–1, number of grains panicle–1, number of sterile spikelets panicle 1, 1000-grain weight, grain yield and straw yield were found to be highest for no leaf cutting which was statistically similar to cutting at 21 DAT but 1000-grain weight was also similar to cutting at 35 DAT and lowest for cutting at 49 DAT. Amount of green forage and forage dry matter were highest for cutting at 49 DAT. It may be concluded that there is a tremendous possibility to get green forage and grain or seed from the same rice plant.

  The efficacy of three fungicides viz. Tilt 250 EC, Bavistin, Pencozeb and botanicals viz. Allium sativum (clove), Nigella sativa (seed), Lawsonia alba (leaf) and Cymbopogon citratus (oil) were evaluated for leaf blight (Bipolaris sorokiniana) and grain yield of wheat cv. Kanchan under field condition. All the fungicides showed significant effect in controlling leaf blight of wheat cv. Kanchan. The highest reduction of the disease was recorded in plots that received Tilt 250 EC (0.1%) followed by Pencozeb (0.2%). Maximum grain yield of 3.89 t/ha with the gross margin of US$ 881.24/ha which 22.80% increase over the control was obtained by using Tilt which was followed by Pencozeb (10.01%). Among botanicals, leaf extract of Lawsonia alba resulted an increase of gross margin of US$ 731.78/ha which is 1.98% increase over the untreated control. Tilt 250 EC, Bavistin, Pencozeb and Lawsonia alba showed 13.16, 3.71, 9.31 and 8.39 BCR, respectively, while others resulted negative response.
