    A study on management system of commercial layer at Zam Zam poultry farm at Baradighir Par in Chittagong
    (Chattogram Veterinary & Animal Sciences University, Khulshi,Chattogram, 2016-10) UDDIN, MD. JASHIM
    The study was carried out at Zam Zam poultry farm at Baradighir Par in Chittagong for a period of 02/08/2016 to 30/09/2016 to observe management of housing, feeding, lighting, production performance, and disease control practices of 5000 layer birds of Lohmann brown under open housing system. During study period, in case of brooding chicks, feed intake was 17gm/day in 2nd week, 19gm/day in 3rd week and 21gm/day in 4th week of age. Body weight was 56gm, 115gm, 187gm, 238gm respectively at 2nd, 3rd, 4th, 5th week of age. The average body weight gained was 60.67 gm/week. The mortality rate was 0.123% per week. In case of layer, the body weight was observed to be 1.87kg, 1.89kg, 1.94kg and mortality was 0.073%, 0.044%and 0.048% respectively at 33rd, 34th, 35th week of age and average feed intake was 115.79gm/day. As for the hens, per day egg production was 87.27% from 33rd to 35th week of age. The peak production was observed to be 88.18% at 33rd week of age. The mortality was 0.055% per week and total mortality was 0.17% over the total experimental period. It may be concluded that, peak production can be achieved during 33rd week of age

    EFFICACY OF FOUR PLANT EXTRACTS AGAINST RIPTORTUS PEDESTRIS (HEMIPTERA: ALYDIDAE)
    (HAJEE MOHAMMOD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR, 2019-12) UDDIN, MD. JASHIM; Prof. Dr. Md. Alamgir Hossain
    The bean bug, Riptortus pedestris Fabricius (Hemiptera: Alydidae) is a highlypolyphagous and one of the major pests of leguminous crop and many fruit trees, causing serious economic damage in many crops. Plant extracts have long been suggested as alternatives to synthetic ones for pest management because of their high potency, cheaper, available and eco-friendly. The topical spraying and residual methods are used to measure the toxicity and repellency effect of four plant leaf extracts of neem (Azadirachta indica), crown flower (Calotropis gigantean), water pepper (Polygonum hydropiper) and marigold (Tagetes patula) against the R. pedestris. The experiment was conducted in laboratory conditions of the Department of Entomology, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur; during the period from March to August 2019. The plant extracts were prepared with two solvent and applied at three doses viz., 500, 600 and 700 mg/L water. The maximum mortality of adults was recorded while marigold (acetone) and crown flower (acetone) sprayed topically at 48 hours after treatment at 700 mg/L water. These were followed by neem (ethanol) and water pepper (ethanol) extracts at 54 and 72 hours after treatment at700 mg/L water. On the other hand, at residual method the maximum mortality of adults was also recorded while marigold (acetone) sprayed at 72 hours after treatment at 700 mg/L. The result of repellency test showed that all the applied doses had repellency and direct toxicity effects but marigold showed the best response and it possess the repellency class V followed by crown flower and neem. Therefore, marigold and crown flower extracts showed highly potential to control of R. pedestris and can be use for alternative of synthetic chemical pesticides.
