The experiment comprised of two factors- factor a: Planting time (2): T1: 24th January planting; T2: 23th February planting and factor b: Rice variety (5): V1: BRRI dhan29; V2: BRRI hybrid 2; V3: Hera 2; V4: Tia and V5: Taj 1. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Among the different planting time and varieties, 24th January planting and Hera 2 were found superior in terms of yield and yield contributing attributes of rice varieties. Irrespective of planting times, the highest panicle length (24.64 cm), number of effective tillers  hill-1(13.33), filled grains panicle-1 (83.17), 1000-grain weight (25.14 g), grain yield (4.30 t ha-1), straw yield (5.21 t ha-1), biological yield (9.43 t ha-1) and harvest index (45.89%) were achieved. However, Hera 2 provided the highest grain yield (4.64 t ha-1) at 24th January planting compared to other combination. It meant that Hera 2 performed well with 24th January planting. \u0000Asian Australas. J. Biosci.

A total of 12 suspected dead duck samples were collected from commercial farms and local market at Sunamganj, Netrokona and Mymensingh districts. Then, the samples were processed and prepared inocula were inoculated into 9-12 days old duck embryonated eggs. In duck embryonated eggs, several passages (3-4) were performed before infection into DEF cell culture. Presence of viral DNA was confirmed by PCR using the primer for DNA polymerase gene. After PCR confirmation, virus cultured in DEF cell was used for the preparation of formalin (0.12%) inactivated and oil based adjuvanted vaccine and was experimentally injected to 18 ducklings and 5 were kept as control. TCID50 of the selected virus for vaccine preparation was 108.70/ml. The mean passive haemagglutination assay (PHA) titre of sera of samples at 0 days, 7 days and 14 days post vaccination were 4.0±0, 14.22±1.78 and 44.44±4.4, respectively, which indicated significant (p<0.01) increase of antibody titre. Embryonated duck eggs and DEF cell culture are effective for virus isolation and on the basis of PHA test, it could also be suggested that the experimentally developed DP vaccine can be used successfully for the prevention of DP in Bangladesh. \u0000Asian Australas.

At 7 days of lactation 16 deshi cows were randomly divided into 4 groups (n=4 lactating cows in each group). Group T1 was kept as control, Group T2 was treated with domperidone (Motigut®) orally at a dose of 100 mg /day per cow, Group T3 was treated with Black Cumin Seed Powder (BCSP) at a dose of 80 g orally per cow per day and Group T4 was treated with combination of domperidone with Black Cumin Seed Powder (BCSP) as above mentioned doses. All the animals were dewormed and vaccinated at initial stage. Over the course of the trial, observations were recorded for milk production and fat percentage in milk. Milk production were increased significantly (P<0.05) in all treated groups compared to the control group and highest was recorded in combined domperidone with Black Cumin Seed Powder (BCSP) group (Group T4).

A total of 100 meat samples (05 from each market) were collected from randomly selected 20 retail markets of Dhaka city using sterile polythene bags in a view to prevent extraneous contamination. The collected meat samples were then processed and inoculated onto nutrient broth and nutrient agar plates for isolation. The isolated organisms were identified based on staining, motility, cultural and biochemical properties according to standard laboratory methods. The isolated bacteria were also subjected to characterize their antibiotic sensitivity. In the present study, it was revealed that 100% of samples were contaminated by at least one species of bacteria belonging to 5 genera such as Staphylococcus, Escherichia coli, Salmonella, Enterobacter and Bacillus. Out of total 100 meat samples, 56% were contaminated with Escherichia coli whereas 42% were contaminated with Coagulase positive Staphylococcus and 36% were Salmonella species followed by 20%, 14% and 10% were contaminated with Enterobacter species, Coagulase negative Staphylococcus and Bacillus species respectively. A total of 174 bacteria were isolated and identified from raw chicken meat samples inspected of which 29.89% were Escherichia coli, 24.14% were Coagulase positive Staphylococcus, 20.69% were Salmonella species, 11.49% were Enterobacter species, 8.05% were Coagulase negative Staphylococcus and 5.75% were Bacillus species. The antimicrobial sensitivity tests showed that 96.15% of Escherichia coli (50 out of 52), 95.24% of Coagulase positive Staphylococcus (40 out of 42) and 86.11% of Salmonella (31 out of 36) isolates displayed multidrug resistance phenotypes (resistant to more than two antimicrobial agents). All most all the isolates of E. coli, coagulase positive Staphylococcus and Salmonella were more resistant to tetracycline, amoxicillin, ampicillin and streptomycin whereas less resistant to Ceftriaxone and Cefotaxime. The resistance patterns against azithromycin, ciprofloxacin, chloramphenicol, gentamycin, nalidixic acid and kanamycin were fluctuated from 25% to 71.43% among the isolates. This increasing development of multidrug resistance is alarming for the poultry industry and an increasing food safety concern for human. \u0000Asian Australas. J. Biosci.

It performs many functions that are important in maintaining homeostasis in the body. Probably the most important of these functions is the control of body temperature. The skin also protects the body from physical damage and bacterial invasion. The skin has an array of sense organs which sense the external environment and also cells which can make vitamin D in sunlight. A study was undertaken of the prevalence, diagnosis and treatment of dermatological disorders in hospitalized dogs at Madras Veterinary College (MVC), Chennai, India from 1st May to 30th May, 2017. Total 220 cases were observed and recorded that had a dermatological problem. Among the dog pruritus (86%), alopecia (63%), scaling (77%), maculo-papular-pustular lesion (91%) were the most common presenting sign. A diagnosis or recommendation for treatment was done on the basis of the presenting clinical signs, physical examination and various diagnostic tests. In this study most of the cases were diagnosed by multiple and deep skin scrapings (100 cases) and by dermato-histopathology (70 cases). The most frequently diagnosed cases were Malassezia dermatitis, Demodicosis, Scabies and Tick infestation. Tick infestation accounted for the majority of the diagnoses. Systemic antibiotics were prescribed in 9% cases, systemic antifungal drugs were prescribed in 7% cases, systemic glucocorticoids were prescribed in 10% cases, antihistaminic in 6% cases and treatment with an ectoparasiticide was prescribed in 73% cases. \u0000Asian Australas.

Irrigation had three treatments - I1: Irrigation with fresh water, I2: Irrigation with mixed water (fresh water: dairy farm’s wastewater = 1:1) and I3: Irrigation with raw wastewater. There were three fertilizer treatments - F0: No fertilizer, F1: Half of recommended dose fertilizer and F2: Full dose fertilizer. Wastewater contained different nutrients and organic matter, which optimistically contributed to the soil in the maize field. Both irrigation and fertilizer treatments employed different degrees of influence on the soil health. For the effect of irrigation treatments, the highest values of EC (0.223 dS/m), pH (8.18), OC (0.3733 %), total N (0.046 %), P (7.65 ppm), K (33 .08 ppm), Ca (297.80 ppm) and Mg (109.9 ppm) were recorded under the treatment of I3, I1, I1, I1, I3, I1, I2 and I3, respectively, and the lowest values of the soil quality parameters were counted under the treatment of I1, I3, I3, I3, I2, I2, I1, and I2, respectively. In case of fertilizer treatments, the maximum values of the soil quality parameters were obtained under the treatment of F2, F2, F0, F1, F2, F1, F1, and F1, respectively, and the lowest values were obtained under the treatment of F0, F0, F1, F0, F0, F0, F0, F2, respectively.

Hence, three types of silages were prepared from Napier fodder namely-Napier silage, urea and molasses added Napier silage (UMN); and di-calcium phosphate added Napier (DCPN) silage. These types of silage fed to the selected nine lactating Holstein-Friesian crossbred cows and divided into three groups considering three of each. Along with 5 kg of respective silages, ad-libitum rice straw and 3 kg concentrate mixture supplied to each group of cows. Physical attributes of all prepared silages were possessing characteristics of good quality silage. Dry matter content in UMN and DCPN silages were 1.67 and 1.01% higher than Napier silage. UMN silage had 1.59 and 2.33% lower ADF from Napier and DCPN silage, respectively. Again, 1.29% higher NH3-N presents in UMN silage than Napier silage. From 1st to 4th fortnight milk yield data it was found that 23.70, 23.19 and 27.06% milk production increased those cows received Napier, UMN and DCPN silage, respectively.

A total of 40 Cobb-500 Broiler day old chicks were reared in an open sided gable type house for a period of 5 weeks from 24th september to 28th october, 2017. Body weight and feed intake were recorded on day 0, 7, 14, 21, 28 and 35. The experiment was conducted in a Completely Randomized Design (CRD). Birds were randomly distributed into four dietary groups i.e control (T0) with basal diet, T1 with basal diet and growth promoter (GP) @ 2 gm/kg of feed; T2 with basal diet and enzymes (EZ) @ 0.4 gm/kg of feed and T3 with basal diet and GP plus EZ (2 gm/kg + 0.4 gm/kg). The records were kept on body weight, feed intake and mortality while weight gain, feed conversion ratio (FCR) and survivability were calculated. Broiler chicks that received GP and a combination of GP+EZ treatments showed significant improvement in performance (p<0.05) over control with respect to body weight gain, feed conversion ratio, carcass yield. Cost-effectiveness of GP+EZ treatment higher than all other treatments but GP and EZ had almost similar cost-effectiveness. Feeding EZ alone had comparatively less weight gain and almost similar feed conversion ratio compared with GP groups but it’s performance was significantly better than that of control group. This study indicated that the diet containing GP+EZ offered slightly increased benefits to the growth performance of  broilers and these benefits were almost equal to the GP. It is revealed that growth promoter (Aviator™) supplementation with enzymes (Acinor™) is beneficial for broiler production. \u0000Asian Australas. J. Biosci.
