The present work was conducted to evaluate the variability in linear body measurements; to investigate the relationship between body linear measurements and live weight and to predict live weight of F1 Brahman crossbred cattle using body measurements. A total of 123 male and 87 female F1 Brahman crossbred cattle of 6-36 months age and weighing from 63 to 535 kg were used for the study over a period from 2010 to 2014. The study revealed that that most of the morphological measurements were linearly increased with the advances of age. The body weight had highest correlation coefficient with the heart girth around the chest (r=0.96, p12-24 months (r=0.95) group. The stepwise regression models revealed that heart girth singly accounted highest variation (93%) in body weight for all animals. Thus, the general equation for prediction of live weight of Brahman crossbred cattle was Y=4.07HG356 (±6.96) where Y=live weight (Kg), HG=heart girth around the chest (cm). The regression equations for the live weight were Y=2.71HG191 (±13.5), Y=4.05HG357 (±9.77) and Y=4.87HG471 (±23.0) for ≤12, >12-24 and >24 months age groups. The best model for estimating body weight was obtained using HG and body length (BL) for all animals Y=2.83HG+1.80BL392 (±6.69). These results suggested that prediction equations based on HG or in combination of HG and BL can be used efficiently in Brahman crossbred cattle to predict live weight.

Labeo bata is one of the important minor carps in Bangladesh with great demand as good table fish. The study was conducted to observe the breeding performance at different management practices in Mafatema, Rupali, Modhumoti and Anan fish hatchery and disinfection treatments of water, eggs and fry in Jessore, Bangladesh during 10 March 2014 to 15 May 2015. An improvement in broodstock nutrition and feeding has been shown to greatly improve seed production. Protein and lipid percentage of broodstock diet have been identified as major dietary factors. Protein level was 24.77%, 23.47%, 18.08%, 17.78% and lipid level was 11.07%, 9.50%, 7.74%, 8.14% in Mafatema, Rupali, Modhumoti and Anan fish hatchery respectively. Three concentrations of four chemical-formalin (10, 20, 30 mg/L), malachite green (1, 3, 5 mg/L), NaCl (1, 2, 3 g/L) and methylene blue ( 1, 3, 5 mg/L) treatment regimes and a control were compared for efficacy in treating L. bata eggs to prevent fungus and bacterial infection and improve hatch and survival rate of fry. Highest correlation value between absolute fecundity and body weight (r=.938, p

The present study was conducted in three upazilla (Bagerhatsadar, Fakirhat and Rampaul) to investigate the shrimp diseases and culture strategies of Bagerhat district in 2012. Post larvae (PL-13/21) from hatchery and natural were used to stock in the study area. The highest mean stocking density was recorded in the ghers of Rampaul (16796±7729.69 PL/ha), where the maximum survival rate was also found (63.00±11.52 %). The highest dose of lime was recorded as 302.58±50.92 kg/ha at Bagerhat sadar; cowdung was recorded as 605.16±118.46 kg/ha at Fakirhat upazilla and urea was recorded as 29.02±5.84 kg/ha (Bagerhat sadar) respectively. The maximum doses of MP and TSP were recorded as 34.58±4.51 kg/ha at Bagerhat sadar and Fakirhat and 27.79±3.71 kg/ha at Bagerhat sadar respectively. No supplementary feed were fed to shrimp, in where culture dependent on natural foods. The highest shrimp production was found in Fakirhat upazila (667±307.05 kg/ha) and the lowest production was in Rampaul upazilla (497±268.97 kg/ha). Sudden change of pH , low dissolved o2 levels, salinity variations, nutritional deficiency and other environmental changes causes yellow head viral disease (YHD), white spot syndrome viral (WSSV), vibriosis, fusarium and protozoan were recorded during the experimental period.

The main aim of this study was to analyze the comparative study on meristem culture of three important potato cultivars, diamant, cardinal and granula and their shoot formation using meristem tips. Apical meristems were isolated from shoot tips of 25-35 days old field grown plants. After surface sterilization the meristems (0.3 mm) were isolated from the shoot tips. After isolation the apical meristems were placed quickly on M shaped filter paper bridge in culture tubes containing liquid MS medium supplemented with various concentrations and combinations of different plant growth regulators. Meristems showed their first growth response by increase in size and became greenish white in colour. They continued their growth and developed shoots with roots. In the present investigation, among the three cultivars of potato, cardinal were the best responsive cultivars for the resuming new growth of cultured meristems on MS medium supplemented with KIN (0.4 mg l-1) + GA3 (0.5 mg l-1). Cultivar diamant showed comparatively better growth response in the primary culture and granula showed better results in shoot length formation in MS0 medium. Cultivar cardinal proved to be best potato cultivar in case of meristem culture than diamant and granula cultivars.

The research work was conducted on 105 layer chicks with a view to determine the rate of distribution of neurotropic virulent Newcastle disease virus (NVNDV) in various organs following infection through natural (intranasal, intraocular and oral) and parenteral (intravenous, intramuscular and subcutaneous) routes of inoculation at different ages (7, 15 and 28 days of old). Each bird received a dose of 0.2 ml contained 300 ELD50 of reference NVNDV. The highest body temperature (≥1080F) was recorded in the birds of almost all the experimental groups within 48 to 72 hours of PI. Appearance of clinical signs was observed earlier (48 to 72 hours of PI) in parenterally infected birds than those of inoculated through natural routes. The shortest duration (24-48 hours of PI) and longest duration (74-138 hours of PI) of death time were recorded in birds those inoculated through IV and oral routes of infection respectively. Isolation of NDV was positive from day 2 of PI and onward in all the groups with some minor variations in some cases. The CEF system was found more sensitive for the isolation of viruses compare to that of avian embryo. The highest HA titre of NDV was found in the brain tissue followed by lungs and kidney.

Successful recovery after amniotic fluid embolism in a patient undergoing vacuum-assisted vaginal delivery

Amniotic fluid embolism (AFE) is a rare, catastrophic emergency that requires prompt recognition and treatment. Despite early recognition and supportive therapy, the morbidity and mortality remain high. We report a case of AFE after vacuum-assisted vaginal delivery resulting in hemodynamic collapse and subsequent multiorgan failure. Management included mechanical ventilation, extracorporeal membrane oxygenation, and continuous veno-venous hemodialysis. The patient was able to make a full recovery with minimal sequelae.
