To minimize the production cost of poultry and poultry products, it is important to formulate low cost balanced ration utilizing unconventional feed resources. Therefore, the experiment was carried out to measure the effect of substituting soybean meal (SBM) by different levels of shrimp head meal (SHM) to the ration of growing layer pullets. A control corn-soybean layer grower (pullet) diet and four different levels of SHM included diets as substitution of SBMwere fed to five groups of Hisex White pullets from 5th to 18th weeks of age. All groups of pullets fed isocaloric feeds (2765 Kcal kg-1). The control group T0 (0 % SHM+20 % SBM) received grower ration formulated with traditional feed ingredients with no substitution of SBM. The SBM contents of other treatment groups were substituted at the rate of 25 %, 50 %, 75 % and 100 % by the SHM and were adjusted as 5 % SHM+15 % SBM (T1), 10 % SHM+10 % SBM (T2), 15 % SHM+5 % SBM (T3) and 20 % SHM+0 % SBM (T4) keeping other ingredients constant as of control. Cumulative feed intake increased with the increasing level of SHM of diets. Feed cost and mortality rate decreased with the increasing level of SHM in the ration. Significantly lowest FCR at most of the age categories, highest cumulative body weight (p<0.05) at 18 weeks and highest weight at maturity (p<0.05) were found in treatment group fed 5 % SHM. Therefore, it can be concluded that substitution of 25 % SBM of the ration by SHM is suitable for the better performance of growing layer pullets. SAARC J. Agri., 18(2): 125-137 (2020)

Water safety plans (WSPs) is a comprehensive health-based risk assessment and risk management approach to optimizing drinking-water safely from catchments to consumer. The focus of this research is the development and implementation of water safety plans (WSPs) to be used by the water supplier. The study was conducted at 13 districts and 18 upazills (rural and urban) among the whole Bangladesh. The data were collected during March to May, 2008 to conduct the study. In the study, primary data were collected directly from the respondents while secondary data were collected from different records available at different office, internet and journals. It was found that deep tube well and shallow tube well water was used for drinking purposes by 31.43% and 24.29% respondents respectively where as minority of the respondents used other sources. Perception about the safe drinking water for the respondents was found mostly 63% among all the respondents followed by moderately safe 21%. About 54.29% respondents were found to be fully satisfied about their drinking water followed by moderately satisfied 30%. Among all the beneficiaries 82.86% beneficiaries have been indicated communication materials like booklet, leaflet, poster, manuals, etc was available. This investigation found that 83.33% rain water harvesting plant and 66.67% deep tube well water source were in high risk category. The chances of contamination were high in the period of covering the water vessels during storage of water 64.71%. About 88.10% respondents among all the official respondents received the water safety plans training. About 66.67% officials have been responded that no sanitary inspection was done. Most of the respondents (78.57% beneficiaries and 76.19% organizational personnel) had high perception about the selected benefits of water safety plans. Among all the officials and beneficiaries i.e. 66.67% organizational personnel and 75.71% beneficiaries had high perception in selected limitations to implement the water safety plans. Finally 95.24% organizational personnel and 81.43% beneficiaries had high perception about the selected necessities to successful implementation of water safety plans in Bangladesh.

Study results showed that deep tube well and shallow tube well water were used for drinking purposes by 31.43% and 24.29% respondents respectively where as minority of the respondents use other sources. Perception about the safe drinking water for the respondents was found mostly 63% among all the respondents followed by moderately safe 21%. About 54.29% respondents were found to be fully satisfied about their drinking water followed by moderately satisfied 30%. Among all the beneficiaries, 82.86% beneficiaries indicated communication materials like booklet, leaflet, poster, manuals, etc were available. This investigation found 83.33% rain water harvesting plant was in high risk where as, 66.67% deep tube well water source was in high risk category. The chances of contamination were high in the period of covering the water vessels during storage of water was 64.71%. About 89% respondents among all the official respondents did not receive the water safety plans training. About 66.67% officials responded that no sanitary inspection was done. Most of the respondents (78.57% beneficiaries and 76.19% organizational personnel) had high perception about the selected benefits of water safety plans. Among all the officials and beneficiaries that 75.71% beneficiary and 66.67% organizational personnel had high perception in selected limitations to implement the water safety plans. Finally 95.24% organizational personnel and 81.43% beneficiaries had high perception about the selected necessities to successful implementation of water safety plans in Bangladesh.
