“…Men reported that when the scavenging area was limited or the presence of natural feed was scarce, supplementary feeding might be necessary. There was also a great potential in improving the productivity of ducks in low-lying areas through better feeding and management practices [7]. Khan reported that indigenous ducks were well adapted to management in rural conditions of Bangladesh and their meat yield was excellent [8,9].…”

Poultry play a significant role in the subsistence economy of Bangladesh. Ducks are one of the most important poultry species in Bangladesh. Duck rearing is most suitable, popular and profitable in riverine country like Bangladesh. The study was conducted at Babugonj upazila of Barishal district, Bangladesh to evaluate the production performance and constraints of duck rearing under semiscavenging system at farmer's level. Farmers were selected randomly and were divided into control followed by minimum (30%) and maximum (60%) level of supplemental feeding regimes. It was observed that natural feeds were not available ad-libitum all the year round as per the requirement for rearing ducks. It was revealed that the average duck mortality (%) was higher in control group than that of treatment groups. It was observed that the mortality rate of ducks was higher in

“…Water hyacinth has received much attention in recent years due to its potential benefits as animal fodder, aquafeed, water purification, fertilizer, biogas production, etc. Numerous studies have evaluated WH as a feed source to ruminants ( Baldwin et al, 1975 ; Abdalla et al, 1987 ; Agarwala, 1988 ; Islam et al, 2009 ; Sophal, 2010 ), fish ( Okoye et al, 2002 ; Abdel-Fattah, 2003 ) and other animals ( Dey et al, 1983 ; Men et al, 2002 , 2006 ). Water hyacinth control methods fall into three main categories: physical, chemical and biological ( Julien et al, 2001 ).…”

A lab-scale ensiling study was carried out to investigate the fermentation quality of water hyacinth (WH) supplemented with molasses, rice bran, as an absorbent, and an inoculant in the form of fermented vegetable juice and their combinations. After wilting the water hyacinths for 7 h to a dry matter (DM) content of 240 to 250 g/kg, the following treatments were applied: i) Control (C), WH only; ii) WH with sugarcane molasses at 40 g/kg WH (CM); iii) WH inoculated with fermented vegetable juice at 10 ml/kg WH (CI); iv) CM and CI (CMI) combined; v) WH with 150 g rice bran/kg WH (CA); vi) CA and CI combined (CAI); vii) CA and CM combined (CAM); and viii) CA, CM and CI combined (CAMI). After application of additives, the differently treated forages were mixed and ensiled in triplicates in 1,500-ml polyethylene jars. After ensiling for 3 d, pH values in all treatments, except C and CI, had decreased to approximately 4.0 and remained low till 14 d. After 56 d, pH had increased between 0.4 to 0.9 pH-units compared to those at 14 d. The ammonia nitrogen (NH3-N) concentration ranged from an acceptable level in treatment CM (8 g/kg N) to a high NH3-N value in treatment CMI (16 g/kg N). Lactic acid formation was higher in CI than in all other treatments. Butyric acid contents, which indicate badly fermented silages, were low in all silages (<2 g/kg DM). There were two-way interactions (p-values from <0.001 to 0.045) for almost all fermentation end-products and pH, except for the molasses×inoculant interaction on NH3-N (p = 0.26). Significant 3-way interactions were found on all observed variables except for weight losses of silages. It is concluded that conserving wilted WH as silage for ruminants may be improved by the addition of molasses or rice bran.
