This study intended to compare the productive performance of three different layer raising systems; conventional cage (CC), barn (BR) and aviary (AV). The AV is welfare bestowed housing that allows free locomotion for birds within the BR. The BR allows bird's free locomotion inside BR but without multilevel structures. Both pullets and cockerels were housed together in both AV and BR, but only pullets in CC. Seventeen weeks old Lohmann Brown Lite (n = 800) pullets were housed in AV during this study. The same age layer pullets were simultaneously assigned to either at CC or BR to compare egg production performance with AV. The duration of experiment was 40 weeks (from 21st to 60th week). There were no remarkable differences in egg production, hen day egg production (HDEP) and average egg weight among three rearing systems. First 20 weeks (phase-1) average HDEP (%) of AV, CC, and BR were 85.9, 88.8, 87.1 and average egg weights (g) were 57.5, 59.9, and 56.9 respectively. Those of the remaining 20 weeks (phase-2) were 87.1, 87.9, 85.5 and 64.2, 63.0 62.1, respectively. Daily feed intakes (122 g, 110 g, 125 g); feed conversion ratio (2.4, 2.1, 2.5) and daily egg mass (53.9 g, 54.4 g, 52.8 g) data from AV, CC, and BR were not influenced significantly by the respective raising systems. Daily feed intake of layers in both AV (124 g) and BR (127 g) tended to be higher than that in CC (113 g) during phase-2. Overall, exterior egg quality (dirty and cracked eggs) in both phases was superior in BR compared with AV and CC, whereas CC generated intermediate results. This study indicated that the HDEP per se in AV and BR were not significantly different from that in CC. The study implied that the facility depreciation cost for AV and cost for increased feed intake in AV compared to CC are believed to be critical to evaluate the cost effectiveness of egg production in AV.

Ahammed, Musabbir,Ohh, Sang Jip The Korean Society of Poultry Science 2013 韓國家禽學會誌 Vol.40 No.1

With an increasing concern on laying hen welfare, barn system has appeared as one of the alternatives to replace the conventional cage. This study was conducted to compare the early laying performance and egg quality at the barn system with those at the conventional cage. A total of 288 shaver-579 brown layers were used for 9 weeks ($21^{st}$ to $30^{th}$ weeks of age) feeding study. Feed consumption and egg weight were significantly (P<0.01) higher at barn than at cage. However, there were no significant differences between two housing systems on hen day egg production (HDEP), egg mass, body weight, feed efficiency and livability. In case of egg quality parameters, shell thickness, albumen height and Haugh unit were significantly (P<0.05) different between two systems. Haugh unit and albumen height were significantly higher in eggs produced at cage (88.97 and 8.16 mm) compared than those produced at barn (83.11 and 6.87 mm), whereas shell thickness was thicker in eggs produced at barn than those produced at cage. Shape index, breaking strength, blood spots and yolk index data were not influenced significantly by the types of housing system. To implement welfare bestowing production, this study showed that the barn system can replace the conventional cage without serious sacrifices on starting phase egg production. In addition, this study suggested that the barn system need to be optimized in view of daily feed consumption.

Geoinformatics based assessment of coastal multi-hazard vulnerability along the East Coast of India

K. K. Basheer Ahammed,Arvind Chandra Pandey 대한공간정보학회 2019 Spatial Information Research Vol.27 No.3

Climate change is one of the major threatens that coastal areas facing, and these coastal areas already stressed by large population. Past 4 decades tremendous tropical cyclones and associated flood are dismantled the coastline and resulted inundation and displacement of the coastal landforms. In the present study, coastal multi hazard vulnerability mapping has been carried out along the Krishna– Godavari deltaic plain, eastern coast of India. The study area consisting of four district include East Godavari, West Godavari, Krishna and Gundur which are the area affected by coastal hazards and climate variability. The area witnessed a high erosion rate up to 18 m/year in comparison to other regions in the state. Further this area exhibit low elevated topography, therefore sea level rise would lead to permanent inundation. In the study also identified about that 1147 sq km area is falling under multi hazard zone and around 102 coastal villages are under threat. This study revealed that the use of multi layer information combined with geospatial tools is most reliable and coast effective approach for disaster preparedness and adaptation. The result obtained from the present study may serve the baseline information for disaster management planning in the area.

Aditya, Siska,Ahammed, Musabbir,Jang, Seong Hun,Ohh, Sang Jip Asian Australasian Association of Animal Productio 2017 Animal Bioscience Vol.30 No.2

Objective: This study was conducted to investigate the effect of dietary onion (Allium cepa) extract (OE) supplementation on growth performance, apparent total tract retention (ATTR), blood profile, carcass characteristics and meat quality in broilers. Methods: Four hundred male broiler chicks (Ross 308, 3-d old) were randomly allocated to four dietary treatments for 28 d feeding trial. Each treatment has five replications with 20 birds each. Four dietary treatments were designated according to the OE supplementation levels (0 as control, 5, 7.5, and 10 g of OE per kg of basal diet respectively). On d 28, a total of 20 birds from each treatment were subjected for ATTR, serum biochemical assay, carcass characteristic and organ weight measurement. Results: Overall weight gain of OE 7.5 g/kg group was higher (p = 0.04) than control group. The ATTRs of dietary energy (p<0.01) and ether extract (p = 0.04) linearly increased with increasing levels of dietary OE. However, no difference in ATTR of dry matter and crude protein was evident. Furthermore, serum IgG concentration increased linearly (p<0.01) and quadratically (p = 0.03) with increasing OE supplementation. No differences in carcass dressing weight and amount of abdominal fat by treatments were observed. Also, the weight of organ including immune organ was not different among the treatments. The TBARS values of 10 d stored breast meat decreased linearly (p<0.01) and quadratically (p<0.01) with increasing dietary OE levels. The meat color was also affected, with lower (p<0.01) redness score in meats from OE supplemented groups. This study showed that dietary OE improved broiler weight gain presumably by increasing feed intake and ATTR of both energy and ether extract. The dietary OE increased serum IgG level and meat anti-oxidation capacity. Conclusion: This study implies that the recommended level of dietary OE supplementation could be beneficial for improving broiler performance and meat quality.

Jefferson Raja Bose,Nizar Ahammed,Lazarus Godson Asirvatham 대한기계학회 2017 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.31 No.4

The heat transfer performance of a vapor chamber and its effectiveness in the cooling of electronic devices are experimentally and theoretically investigated in the present work. The power transistor in the circuit board usually operates with electric power that ranges from 15 W to 100 W, which is the heat input to the simulated processor. The heat flux varies between 3300 and 22000 W/m 2 . The simulated processor is cooled with the forced and induced air cooling methods with and without the use of the vapor chamber. Results show a maximum temperature decrease of 26 % and a maximum increase in the convective heat transfer coefficient of 36 %. The minimum value of the thermal resistance through the vapor chamber and the total thermal resistance is 0.195 and 0.82 °C/W, respectively. The experimental results are compared with the ANSYS predicted values.

Kader, Md. Abdul,Ahammed, Akash,Khan, Md. Sharif,Ashik, Sheikh Abdullah Al,Islam, Md. Shariful,Hossain, Mohammad Uzzal Korea Genome Organization 2022 Genomics & informatics Vol.20 No.1

Litorilituus sediminis is a Gram-negative, aerobic, novel bacterium under the family of Colwelliaceae, has a stunning hypothetical protein containing domain called von Hippel-Lindau that has significant tumor suppressor activity. Therefore, this study was designed to elucidate the structure and function of the biologically important hypothetical protein EMK97_00595 (QBG34344.1) using several bioinformatics tools. The functional annotation exposed that the hypothetical protein is an extracellular secretory soluble signal peptide and contains the von Hippel-Lindau (VHL; VHL beta) domain that has a significant role in tumor suppression. This domain is conserved throughout evolution, as its homologs are available in various types of the organism like mammals, insects, and nematode. The gene product of VHL has a critical regulatory activity in the ubiquitous oxygen-sensing pathway. This domain has a significant role in inhibiting cell proliferation, angiogenesis progression, kidney cancer, breast cancer, and colon cancer. At last, the current study depicts that the annotated hypothetical protein is linked with tumor suppressor activity which might be of great interest to future research in the higher organism.
