Moniruzzaman, M.,Hashem, M.A.,Akhter, S.,Hossain, M.M. Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.10
The experiment was conducted to find out the effect of 4 feeding systems on growth, feed intake, eating behavior, lactation performance, gestation period, post-partum heat period, conception rate and parasitic infestation of Black Bengal goat. Twenty four does of approximately 1 year of age were randomly selected for 4 treatment (feeding systems) groups having 6 replications in each. Treatments were stall feeding ($T_1$), tethering ($T_2$), restricted grazing ($T_3$) and grazing ($T_4$). $T_1$ group was housed continuously and adequate amounts of natural grass were supplied for ad libitum feeding. $T_2$ group was tethered for grazing natural grass from 8 a.m. to 4 p.m. being moved at one hour intervals. Goats of $T_3$ group were allowed grazing from 8 a.m. to 1 p.m. $T_4$ group was grazed from 8 a. m. to 4 p.m. Concentrate supplement was given at the rate of 150 g per day per goat for all of the treatment groups. Duration of experiment was 219 days. Daily live weight gain was significantly (p<0.05) higher in case of stall fed goats than that of others. DM intake also significantly (p<0.05) differed among the treatment groups and was 3.40 3.95, 3.76 and 4.05 per cent of their live weight for stall feeding, tethering, restricted grazing and grazing groups, respectively. Rate of rumination was significantly (p<0.05) higher in case of tethering group of goats than that of others. Birth weight of kids, milk yield, lactation period and post-partum heat period were significantly higher in case of stall fed goats than others. Tethering group showed significantly (p<0.05) higher litter size than others. Infestation rate of Fasciola was significantly (p<0.05) higher in the grazing group. In conclusion, it may be stated that among these feeding groups overall performance of stall fed goats was more satisfactory, and that the tethering group showed better performance than the others.

Polyethene is a global environmental threat, whereas jute (Corchorus spp.) fber is biodegradable, eco-friendly and can be used as a substitute for polyethene. Jute is a short-day plant and cultivated in March to July in Indian subcontinent for bast fber production. This season-bound cultivation nature hampers continuous supply of bast fber in the industry. In addition, its long cultivation period creates difculties to accommodate other high-value crops. To address these issues, a short life span (early fowering) jute genotype is extremely felt in jute growing areas of the world. But, unfortunately such variety has not been developed yet through both conventional and biotechnological approach. Accordingly, we adopted chemical mutagenesis by establishing LD50 (Lethal Dose) of EMS (Ethyl Methane Sulfonate) at 150 mM with 4h’ incubation for Capsularis jute seed. A novel mutant was found named—Komola, which showed a shorter lifespan than its ancestor by fowering at 70 days instead of 120 days. In addition, the mutant's stem and petiole was coppery-red instead of green. Molecular analysis revealed four SNPs in PMIR1 (Plastid Movement Impaired 1 Related 1) and two clade deletions in ELF3 (Early Flowering 3) genes from stable M4 generation. Histochemical and biochemical analyses explained this genotype’s lower content of lignin. This mutant could be used as future breeding material for the development of year-round cultivable jute genotype along with ofer up accommodation of other high-value agricultural crops in cropping pattern with a good source of year-round supply of bast fber to the industry

Moniruzzaman, M.,Hashem, M.A.,Akhter, S.,Hossain, M.M. Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.1
The experiment was conducted to find out the effect of four feeding systems namely; stall feeding, tethering, restricted grazing and grazing on carcass characteristics of Black Bengal goat. Twenty four does of approximately 1 year of age were randomly selected for four treatments of feeding systems having 6 replications in each. Stall fed goats were kept into house all time and adequate amount of natural grass were supplied for ad libitum feeding. Goats of tethering group were tethered for eating natural grass from 8 a.m. to 4 p.m. and were transferred after one hour interval for changing the grazing place. Goats of restricted grazing group were allowed for grazing from 8 a.m. to 1 p.m. Goats of grazing group were grazed for 8 a.m. to 4 p.m. Concentrate supplement was given at the rate of 150 g per day per goat for all of the treatment groups. Goats were slaughtered after the experiment of 219 days. Body length and height at wither were significantly higher in stall feeding group than others. Average dressing percentage were 42.18, 39.0, 36.79 and 34.0 for stall feeding, tethering, restricted grazing and grazing groups, respectively. Dressing percentage varied significantly (p<0.05) among feeding groups. Caul fat and empty gut weight differed significantly (p<0.05) in all of the feeding systems but others non-carcass parameters did not differ significantly. Percentage of dry matter and ether extract were also significantly (p<0.05) higher in stall fed groups. In conclusion, among four treatment groups, performance of stall fed goats were most satisfactory and then tethering showed better performance than any other groups.

Common fi g ( Ficus carica L.), an economically-important fruit species widely cultivated in the Mediterranean Basin, is gainingincreasing interest in the tropical and subtropical regions. A vast genetic diversity of common fi g is available; however,systematic studies of cultivar performance in a particular new environment are scarce. The objective of this study was toevaluate the performance of 17 common fi g cultivars grown under the Malaysian tropical climate. Evaluation was based on15 parameters relevant to fruit yield, fruit quality and pest susceptibility. The results showed variable performance amongthe cultivars tested; 10 cultivars performed well for orchard establishment. Cultivar ‘A134’ produced the highest fruit yieldper plant (3410 g) compared to the average yield of the cultivars studied (2500 g). Cultivars ‘Fen Chan Huang’ and ‘Wuhan’produced the highest number of fruits per plant, 119 and 82 fruits, respectively. Mealybug infestation and ostiole-end splittingare major limitations to fi g cultivation in Malaysia. Cultivar ‘Longue d’Aout’ was the most susceptible to mealybuginfestation; whereas cultivar ‘B110’ was the most resistant. Above 60% of the fruits of cvs. ‘Brunswick’ and ‘Qing Pi’ hadsplit ostiole; however, this was less than 20% in cvs. ‘Longue d’Aout’ and ‘Alma’. This study facilitates successful farmingof fi gs in Malaysia and provides insights for future development programs.

In salinity affected areas, variation in salinity level is the major cause of yield fluctuations in rice during the dry season (boro season). To sustain food security in Bangladesh, plant breeders need to develop new rice varieties which are higher yielding, salinity tolerant and stable across different environments. We evaluated the yield performance and stability of 51 rice elite genotypes including two salinity tolerant rice varieties (BRRI dhan67 and BINA dhan-10) and the dominant boro rice variety (BRRI dhan28) in three locations, including a salinity “hotspot”. Best linear unbiased predictions (BLUPs) were used to identify superior genotypes from multi-environment trials. Selection from a large set of candidates is required for evaluation and recommending a new variety for release. Estimated breeding values (EBVs) were used to select parents. Six parents with high EBVs (BR8982-5, IR 87870-6-1-1-1-1-B; BR8943-B-1-2-7, BR8940-B-17-4-7, A69-1 and BR8943-B-5-5-14) would be useful as parents to develop new breeding populations. To evaluate yield performance and stability across environments, we used additive main effects and multiplicative interaction (AMMI) model using a randomized complete block design with two replications. Genotype × environmental analysis was performed using GGE biplot analysis. Based on yield performance and stability, BR8982-5, IR 87870-6-1-1-1-1-B, BR8943-B-1-2-7, BR8940-B-17-4-7, A69-1 and BR8943-B-5-5-14 were promising across the tested environments, as they showed yield advantages over check varieties. The results in this study will be useful for selecting the elite lines suitable for salinity affected areas and parents for rapid breeding of salinity tolerance.

The nutritive value and the effect of tannins on the utilization of foliage from three commonly used legumes, Acacia nilotica, Albizia procera, and Sesbania acculeata, were determined. Three mature rumen-fistulated bullocks were used to study in sacco degradability and twelve adult sheep were randomly allocated on the basis of live weight to 4 groups of 3 in each to study the in vivo digestibility of the foliages. In all foliages, the contents of crude protein (17 to 24% of DM) were high. Fibre was especially high in Albizia (NDF 58.8% of DM vs. 21% in Sesbania and 15.4% in Acacia). Contents of both hydrolysable (4.4 to 0.05%) and condensed tannins (1.2 to 0.04%) varied from medium to low in the foliages. Acacia contained the highest level of total phenolics (20.1%), protein precipitable phenolics (13.2%) and had the highest capacity to precipitate protein (14.7%). Drying in shade reduced the tannin content in Acacia and Albizia by 48.6 and 69.3% respectively. The foliages ranked similarly for each of the different methods used to estimate tannin content and activity. Acacia and Sesbania foliage was highly degradable (85-87% potential degradability of DM in sacco), compared to Albizia (52%), indicating a minimal effect of tannins in Acacia and Sesbania. Yet, in vitro, the tannins in the Acacia inhibited microbial activity more than those in Albizia and Sesbania. Following the addition of polyethylene glycol to neutralise the tannins, gas production and microbial growth increased by 59% and 0.09 mg RNA equiv./dg microbial yield respectively in the Acacia, compared to 16-17% and 0.06 mg RNA equiv./dg microbial yield in the other foliages. There was a trend for low in vivo apparent digestibility of N in the Acacia (43.2%) and Albizia (44.2%) compared to the Sesbania (54.5%) supplemented groups. This was likely to be due to presence of tannins. Consistent with this was the low N retention (0.22 and 0.19 g N/g NI) in sheep supplemented with Acacia and Albizia compared to that for the Sesbania (0.32). Similarly, a trend for poor microbial N yield was observed in sheep fed these foliages. Across the foliages tested, an increase in tannin content was associated with a reduction in ruminal fermentation, N digestibility and N retention. For overall nutritive value, Sesbania proved to be the superior forage of the three tested.

Hadoop–a popular open-source implementation of MapReduce is widely used for the analysis of large datasets. The current Hadoop implementation assumes that computing nodes in a cluster are homogeneous in nature. In this paper we evaluate performance of Hadoop Platform and Oracle for Distributed Parallel Processing in large datasets. For evaluation, we implement a prototype of a virtual datacenter using distributed and parallel computing technology. The purpose of this paper is to reduce datacenter implementation cost using commodity hardware and provide high performance. Hadoop is installed on a commodity Linux cluster the distributed processing of large data sets across clusters of computers using distributed and parallel computing architecture. This paper also helps to explain about some new technology and framework which are open source; that can easily utilize those technologies for our complex data analysis which resembling structured, semi structured and non-structured data. Here we tried to demonstrate a performance comparison by executing some queries between distributed parallel computing system and traditional single computing system. For the simulation of the infrastructure Hadoop cluster has been used for distributed parallel processing and Oracle 11g is used for traditional single processing system. We prepare three virtual host for Hadoop cluster and a high-end hardware for Oracle 11g.
