A serological survey on the prevalence of antibodies to Newcastle disease virus (NDV) was carried out in broilers chicken in Dinajpur districts. For this reason, a total of 75 serum samples were collected form broiler chickens and samples were divided into five groups, each group contain 15 chickens. Group E did not receive any vaccine and served as a negative control group. Groups A-D were vaccinated with different vaccination programs against NDV. From this experimental work the principal objectives of the present investigation it may be stated that production of Hl-antibody was higher in birds of group D vaccinated with CevacVitapest-LR compared to those of group A vaccinated with Medivac NDLaSotaR, group B vaccinated with BCRDV(R) and group C vaccinated with Izovac. B, HitchnerR. Thus, the CevacVitapest-LR was found to be superior to some extent than Medivac ND-LaSota, BCRDVR, Izovac B, Hitchnert. However, as regards vaccination of chicks against NDV in earlier days the use of lentogenic strains are recommended although it should be kept in mind that vaccination with LaSota strains would cause considerately greater problems in young susceptable birds than Hitchner B1 strain and even through LaSota induces a stronger immune response. \u0000Asian Australas.

The collected data was analyzed by SPSS 17.0 Statistical computer programme. The body coat color of Boer goat was white with reddish-brown head, ears and neck and the body coat color of Jamunapari goats was variety of colors. Both of them had horns but polled Jamunapari goats were also found. The body weight significantly (p<0.001) differed between Boer goat (52.36±5.97 kg) and Jamunapari goat (39.26±3.00 kg). Horn length of Boer goat (19.01±1.29 cm) was significantly (p<0.001) higher than Jamunapari goat (7.98±0.71 cm). Head width and teat length of Jamunapari goat (33.82±0.85 cm and 9.15±0.89 cm) were significantly higher (p<0.05) than Boer goat (30.23±0.63 cm and 5.80±0.87 cm).

The experiment was conducted in three ponds at Rahmatpur of Muktagachha Upazila of Mymensingh district from 5 August to 5 December, 2013. The size of ponds were 24 (T1), 24 (T2) and 24 (T3) decimal with an average depth of 4 feet. Three different stocking densities were tested, namely treatments T1 (400 fish /decimal, 350 Vietnamese koi and 50 magur); T2 (450 fish /decimal, 400 Vietnamese koi and 50 Magur) and T3 (550 fish /decimal, 500 Vietnamese koi and 50 Magur). Ruposhi Bangla feed was used in all treatments two times daily from the beginning of the fry stocking. The initial weight of Vietnamese koi and Magur were 5±0.00 g and 2±0.00 g respectively. The initial length of Vietnamese koi and Magur were 2.54 and 3.50 cm respectively. The average highest final weight gain of Vietnamese koi was (138.71±0.03 g) observed in T1 and followed by T2 (135.65±0.12 g) and T3 (129.29±0.49 g). Similarly, the average highest final weight gain of Magur (76.00±0.58 g) was observed in T1 and followed by T2 (68.36±0.43 g) and T3 (62.61±0.58 g) respectively. The average highest final length gain of Vietnamese koi (17.38±0.05 cm) was observed in T1 and followed by T2 (17.00±0.04 cm) and T3 (16.33±0.03 cm). Similarly, the average highest final length gain of Magur (21.30±0.09 cm) was observed in T1 and followed by T2 (17.00±0.05 cm) and T3 (15.87±0.02 cm) respectively. The survival rate of the stocking Vietnamese koi and Magur were recorded 95.14 and 72.00 % in T1; 93.25 and 64.00% in T2; 90.80 and 68.00 % in T3 respectively. Fish production in T1, T2 and T3 were 48.93; 52.79 and 60.83 kg/decimal/120 days, respectively. The total production of T3 was increased with the increasing of stocking density compare to T2 and T1. The benefit-cost ratio (BCR) was higher in T3 where BCR was 1.67 and on the other two treatments BCR was 1.53 in T2 and 1.52 in T1 although the highest production was obtained in T3 but individually growth performance of Vietnamese koi and Magur were higher in T1. Based on the result of the present experiment, farmers could be suggested to rear Vietnamese koi with Magur at the stocking density of 550 fish/decimal (500 Vietnamese koi and 50 Magur) which was the highest density tried to get more production and financial benefit. Further experiment need to be conducted by taking higher density than the 550 fish/decimal for the optimization of stocking density to get more production and benefit. \u0000Asian Australas. J.

The soil was silt loam in texture having pH 6.27, organic matter content 1.95%, total N 0.14%, available P 3.16 ppm, exchangeable K 0.09 me% and available S 10.5 ppm. The experiment was laid out in a randomized complete block design with three replications. There were eight treatment combinations including T1 (Control), T2 (PU, 104kgN/ha), T3 (USG, 104kgN/ha), T4 (USG, 78kg N/ha), T5 (USG, 52kg N/ha), T6 (NPK briquette, 104kgN/ha) and T7 (NPK briquette, 78kg N/ha) and T8 (NPK briquette, 52kg N/ha). All the treatments except T6, T7 and T8 received 20 kg P and 50 kg K/ha as TSP and MoP, respectively. Treatments T6, T7, T8 received NPK briquettes fertilizer. Prilled urea was applied in three equal splits. USG and NPK briquettes were applied at 10 DAT and the briquettes were placed at 8-10 cm depth in the center of four hills in alternate rows. The yield attributes, and grain and straw yields of BRRI dhan46 responded significantly to the application of PU, USG and NPK briquettes under flooded condition. The highest yields of grain (5828 kg/ha) and straw (6116 kg/ha) were recorded in T3 and the lowest values of grain and straw yields (3522 and 3783 kg/ha, respectively) were found in the control. Deep placement of N fertilizers also enhanced the N use efficiency, N uptake and apparent recovery by BRRI dhan46. The maximum N use efficiency (22.17 kg grain increase per kg N applied) was found in T3 and the minimum value (9.31 kg grain increase per kg N applied) was recorded in T8. The results reveal that the deep placement of USG (104 kg N/ha) accelerated the N uptake, N recovery and N use efficiency by BRRI dhan46 as compared to other treatments. Therefore, application of 104 kg N/ha as USG may be recommended for profitable cultivation of aman rice, BRRI dhan46. \u0000Asian Australas. J. Biosci.

A total number of 160, male one day old, Jinding ducklings were used in this study. All ducks were weighed individually and distributed randomly among 4 treatments, each treatment includes 40 ducklings were nearly similar in initial average body weights and each treatment was 4 blocks of 13 ducklings. Chemical analysis for rations was applied and different productive and economic measures applied. The results showed significant differences (p>0.05) among all groups for the final body weight where the control groups it was 389.40±251.87 gram and for T2, T3, and T4 the final body weight were 641.93±503.98, 693.55±500.33, 693.55±500.33 respectively.

As source of extracellular protease, three types of enzymes viz. purified papain, papaya peel and ginger were used in triplicates and these enzymes were found to be very effective to break the fish muscle protein down. Highest protein concentration (89.12%) was found in peptides using purified papain followed by using papaya peel (87.46%) and ginger (76.04%). Solubility, foam expansion and emulsifying activity index (EAI) were determined to analyze its functional properties. Purified papain showed the highest solubility (84%) followed by 80% and 72% in FPP using papaya peel and ginger respectively.  Three sample concentrations (0.1%, 0.5% and 1%) were used in triplicates to determine foam expansion percentage and EAI. The stability of foam was increased and EAI was decreased with increasing concentrations of samples. The study concluded that papaya peel would be a source of low-cost protease enzyme as an alternative of purified papain as the protein percentage did not vary significantly. \u0000Asian Australas. J.
