Abstract: A study was carried out to compare and evaluate the percentage of reconstitution media (tap water, hot water, 5% NaCl and 5% Ca(OH)2) uptake of stored dried control, irradiated (1 kGy) and heat treated (50 °C) spotted spanish mackerel Scomberomorus guttatus at room temperature for 1, 4 and 24 dipping hours upto 180 days of storage period after each 30 days of intervals. Maximum media uptake found in 5% Ca(OH)2followed by 5% NaCl, hot water and tap water in all samples. The highest (121.81%) and lowest (4.07%) percentage of media uptake observed in Ca(OH)2 and tap water respectively from the irradiated fish sample. This study also reveals that percentage of media uptake depends on reconstitution medias and dipping hours significantly but not with the various samples.

Abstract: Weather plays an important role in our farming system. In greenhouse or internal farming system, weather monitoring is important. For better production and maintenance, it is important to monitor. This project is developed for forecasting weather parameters like humidity, temperature, soil moisture, and raid detection. Humidity and temperature are monitored for internal temperature. The soil is the most important part of a greenhouse. In this project, soil moisture level is monitored and controlled for maintaining soil moisture level. Rain detection is used in outside of the farm. It detects rainwater and sends a message to the server. It is monitored by using a local server. In remote routing area, it also can be monitored and controlled without physical existence. Also, it is a low-cost weather monitoring system for the agro farm. The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. The monitoring system could be designed by using the sensor. It is useful for forecasting and data analysis process. In this project weather forecasting system is designed by using a sensor. In this project, Raspberry Pi work like a remote monitoring and controlling system for the agro farm.

Abstract: Data on 823 performance records of 537 Friesian cows maintained at the Livestock Experiment Station Bhunikey (Pattoki) District Kasur during the years from 1984 to 2001 were used to investigate various sources of variation for milk yield. The Harvey’s least squares analysis was carried out. The least squares means for milk yield and lactation length were 3391.66 ± 137.97 kg and 278.40 ± 90.17 days, respectively. The two traits were significantly correlated with each other having a correlation coefficient of 0.61 (P<0.01). Lactation length and lactation number were significant (P<0.01) sources of variation for milk yield. The influence of year and season of calving on milk yield was also significant (P<0.01). The milk yield was the highest (3659.48 ± 153.47 kg) among the cows calving during autumn and the lowest (3249.36 ± 151.83 kg) among those calving during humid hot season. The cows calving during spring, winter and dry hot seasons yielded 3424.38 ± 188.16, 3345.91 ± 140.12 and 3279.18 ± 201.29 kg of milk, respectively.

Abstract: A study was undertaken in the Department of Biochemistry, Bangladesh Agricultural University, Mymensingh to evaluate the nutritional status of red amaranth as influenced by three selected pesticides at various dose levels. The results revealed that the level of moisture content ranged from 86.50 to 87.62% in different treatment groups. The highest amount was in T4 where chlorpyrifos @ 0.66 a.i./ha was sprayed at 21 days after emergence and the lowest (86.5%) was in control group (T13) where no pesticide was applied. The dry matter percent was highest in control (13.50%) and slightly lower in treatment groups indicating no significant variation among them. The protein percent was from 5.02 to 5.24 in different treatment groups expressing little higher than the control plants (4.82%). Fat percentage ranged from 0.10 to 0.12 in treatment groups, which were very close to control value. Total sugar was highest (2.10) in T7, T9 and T11 and lowest in T6 (carbofuran). Reducing sugar was 1.15% in T7 (cypermethrin and chlorpyrifos) and 0.98 in T6, while non-reducing sugar seemed to be little higher (1.11%) in treatment groups compared to the control (0.88%). As a whole pesticide studied had very insignificant effect on protein, fat, ash, dry matter and moisture content of red amaranth. The carotene content was highest (10.24 mg 100 gG1) immediately after harvest in T1 and lowest in T8. But the level of carotene decreased to 9.08 mg 100 gG1 in T8, which was statistically insignificant. As far as vitamin C is concerned, the level was reasonably good in all the treatments as well as control plants immediately after harvest (38.52 mg - 40.41 mg). The level of vitamin C decreased in all the treatment and control plants after 20 minutes cooking (26.21-28.25 mg).

Abstract: Data on 8948 pedigree, breeding and performance records of a purebred herd of Sahiwal cattle maintained at the Livestock Experiment Station Jahangirabad district Khanewal (Pakistan) during the period 1939-98 were analysed. The phenotypic, genetic and residual correlations between first lactation milk yield and some first lactation and lifetime traits were estimated, using Bivariate REML analysis. Phenotypic, genetic and residual correlations between first lactation milk yield and age at first calving were 0.67, 0.61 ± 0.30 and 0.73; between first lactation milk yield and first lactation length were 0.35, 0.48 ± 0.38 and 0.31; between first lactation milk yield and first calving interval were 0.39, 0.46 ± 0.46 and 0.39; between first lactation milk yield and first dry period were 0.35, 0.49 ± 0.46 and 0.30; between first lactation milk yield and lifetime milk yield were 0.02, 0.01 ± 0.77 and 0.05. Positive and high genetic correlation between first lactation milk yield and age at first calving indicated that the selection for higher first lactation milk yield would increase the age at first calving, which is not advantageous.

Abstract: A study was conducted to determined the effect of replacement of soybean meal (SBM) with locally available oilseed meals i.e. Canola (CM) and Sunflower meal ( SFM ) on performance of broiler chicks. Five different experimental rations A, B, C, D and E containing SBM 15%, SBM and CM 7.5% each, CM 15%, SBM 7.5% plus 3.75% CM and SFM each and SFM 15% respectively, were offered to the day-old broiler chicks up to six weeks of age. The effect of different rations was observed in terms of the performance parameters of broiler chicks. The results showed that the weight gain, feed consumption, feed conversion ratio, carcass weight and dressing percentage were comparatively improved (P<0.05) where SBM was used as a source of vegetable protein. However, CM and SFM could successfully replace 50% of SBM. The 100% substitution of SBM with SFM resulted in high, feed consumption with poor weight gain, feed conversion ratio, carcass weight, dressing percentage and liver enlargement, which could be attributed to comparative poor nutritional value and mycotoxin susceptibility of SFM.

Abstract: An attempt was made to study several parametric characteristics of stems and leaves of six selected and one standard clones of Bangladesh tea in order to identify and select superior clone in tea. Out of ten morphological characters, two characters of stem (stem circumference and height of the first branching position), five characters of 5thleaf (leaf length, leaf breadth, leaf length/breadth ration, leaf size and leaf angle in degree) and three characters of pluckable shoots (internodal length, shoot density and yield of green leaf as well as made tea per hector) were considered qualitatively and quantitatively following IPGRI’s guidelines with some minor adjustment and analyzed statistically. It was noticed that all clones were significantly different in respect of stem circumference, leaf length, leaf breadth, leaf length/breadth ratio, leaf size, leaf angle, internodal length of fish leaf to mother leaf, shoot density and yield. Considering different morphological and yield character MZ/39 was found most suitable followed by B2 × T1 and SDL/1 for commercial cultivation in Bangladesh.

Abstract: Caprine fascioliasis plays an important role of major constraints to small ruminant production in Bangladesh. This study was conducted in Sylhet district of Bangladesh to determine the prevalence of fascioliasis in Black Bengal goats of different age groups, sex and in seasons. In this study, livers of male and female goats were collected randomly from slaughter house during a period of 1 (one) year (October, 2007 to September, 2008). A total of 318 livers examined of which 66 were found to contain Fasciola gigantica. The overall prevalence rate was 20.75%. Fascioliasis was observed significantly higher in older (58.33%), female goats (36.79%) and during the rainy season (26.16%). The estimated economic losses due to condemnation of liver were 5.59% which amounted to US$ 115.44 per thousand liver of slaughtered goat. The prevalence was significantly different (P≤0.05) in different age groups and sex of the animals. The present study indicates that Fasciola infection in Black Bengal goats associated with age and sex of the animals; and seasons of the year. To control the disease in this area, appropriate preventive control strategies have to be designed to reduce the impact of the disease on goat production in Bangladesh.

Abstract: Trace metals concentration and proximate composition of raw and boiled silver pomfret (Pampus argenteus) from coastal area and retail market were determined to gain the knowledge of the risk and benefits associated with indiscriminate consumption of marine fishes. The effects of cooking (boiling) on trace metal and proximate composition of silver pomfret fish were also investigated. Trace element results were determined by the Energy Dispersive X-ray Fluorescence (EDXRF) Spectrometer wherein fish samples from both areas exceeded the standard limits set by FAO/WHO for manganese, lead, cadmiumm and chromium and boiling has no significant effects on these three metal concentrations. Long-term intake of these contaminated fish samples can pose a health risk to humans who consume them. 1. Introduction Fish is a healthy food for most of the world’s population particularly developing countries in contrast to meat, poultry, and eggs. Fish provides comparatively cheap and readily available protein sources (about 15 to 20 percent) in addition to long chains of n-3 fatty acids, amino acids, vitamins, and minerals which contributes to healthier nutritional options for a balance dietary intake [1, 2]. Among the all fishes, marine fish are very rich sources of protein and various mineral components. The total content of minerals in raw flesh of marine fish is in the range of 0.6–1.5% of wet weight [3]. Trace metals are present in water from natural sources such as the rocks of the sea bed and also accumulated as a result of human activities such as emissions from industrial processes. These elements are taken up by marine fishes which are higher up the food chain. As a result, the concentrations of many elements including mercury, arsenic, lead, and cadmium in fish can be relatively high compared to other foods. Many of these metals such as iron, copper, cobalt, manganese, molybdenum, nickel, and zinc are essential trace elements and play important roles in biological systems. Meanwhile, mercury, lead, and cadmium are toxic, even in trace amounts [4]. Moreover, elevated concentration of manganese and nickel has been found to be toxic to aquatic organism [5, 6]. To monitor trace metals concentrations in the coastal environment, marine fishes have been widely used as bioindicators due to their wide range of distribution. Several studies have been carried out on metal pollution in different species of edible fish. Predominantly, fish toxicological and environmental studies have prompted interest in the determination of toxic elements in seafood [7–10]. According to the

Abstract: Growth performance of bighead carp (Aristichthys nobilis) in monoculture system with and withoutsupplementary feeding indicated that supplementary feeding played an important role in better growth ofbighead carp. The average initial weight of bighead carp at the time of stocking was 11.40 ± 3.25g and finalweight of 902.00 ± 4.63g was recorded after 12 months of experiment using organic (cow dung) andinorganic (urea and single super phosphate) fertilizers. The average initial weight at the time of stocking ofbighead carp was 10.3 ± 1.32g and average final weight was 1170 ± 4.85g at the end of experiment usingfertilizers and supplementary feed with 20% crude protein. Significantly higher (P<0.05) weight gain of1170.0 ± 3.25g was achieved in treatment with supplementary feeding compared to 902.00 ± 4.63g withoutsupplementary feeding. Temperature range of 26-33oC (during May to July) was found to be suitable forfish growth, as better weight gain and lower feed conversion ratio were recorded during this period. Lowergrowth was observed during the months of December, January and February, when average temperaturewas 7-15°C.
