“…Fresh duckweed samples contain approximately 94% water and 6% DM. The average nutritive values on a dry matter basis are shown in (Table 1a), (Shammout & Zakaria, 2015b). The analyzed water quality parameters were within the allowed limits set forth in the Jordanian Standard (JS 893/2006) for irrigation.…”

“…Duckweed samples were analyzed and determined according to (AOAC, 2005) (Table1a), (Shammout & Zakaria, 2015b). Crude protein was 26% on 6% DM, although other researchers reported higher crude protein content (Chowdhury et al, 2000; Akter et et al, 2007;Chantiratikul et al, 2010), mostly nitrogen concentration (Leng, 1999), water pH (Goopy & Murray, 2003), different management applied, and if it was collected from a waste lagoon or natural water source, as in this study.…”

“…The cost of animal feed generally accounts for 60% or more of the total production cost of raising poultry (Ministry of Agriculture, 2014), which is generally associated with high cost of important protein sources, such as soybean meal. This has increased the demand for an alternative local protein source for feeding (Shammout & Zakaria, 2015b). Using local protein sources which have a similar quality level to that of soybean meal to replace the imported sources is one solution to reduce production costs.…”

“…Lemna gibba is the Lemna species that has been recorded in water bodies in Jordan (Al-Eisawi, 1982). Other studies were conducted on this species in Jordan for the purpose of evaluation of the role of duckweed in purifying farm irrigation ponds as a natural water bioremediation agent , 2015b. However, the use of this species to replace part of the SBM in poultry diets scarcely received any attention, and there is no information currently available in Jordan about the use of duckweed as a protein replacement in the diet of laying hens.…”

Water lentils (Duckweed [DW])(Lemna gibba), in irrigation ponds, was evaluated by replacing two levels of soybean meal (SBM) on performance and egg quality of laying hens of 54 weeks of age. A total of 72 white Lohmann laying hens were randomly allocated into 3 treatments with 6 replicates/treatment, 4 hens/replicate in a randomized complete block design. Treatments were: control group (DW0%) with (SBM) as the main source of protein, T1 (DW10%) and T2 (DW20%), where duckweed replaced 10% and 20% of SBM for 9 weeks. No significant differences were observed among the dietary treatments in body weight change, feed conversion ratio, egg weight and mortality rate. Replacement with (DW20%) decreased (p<0.05) feed intake, egg laying rate and egg mass. The dry albuminin (DW10%) decreased (p<0.05) from 7 to 9 weeks and in the total period. Yolk pigmentation was highly (p<0.001) improved by the replacement. Blood spots were increased (p<0.05) with (DW20%). Duckweed grown in good quality irrigation water can replace up to 10% of the SBM as a source of protein without adverse effects on hen performance and egg quality in addition to profitability.

Phytoremediation of Lebanese polluted waters: a review of current initiatives

Water pollution is presently considered as a serious apprehension in Lebanon. Heavy contamination load of nutrients, heavy metals and organic pollutants can be highly harmful for human health and detrimental to aquatic life and ecosystems. Phytoremediation in natural and constructed wetlands using aquatic macrophytes present a sustainable plant-based technology recognized as a very efficient option in water treatment. The employment of species such as Phragmites, Sparganium, Lemna sp and other aquatic macrophytes not only helps in pollution cleanup but also conserves aquatic communities. To date, two pilot constructed wetlands, Litani River and Bcharreh have been established in Lebanon. These promising initiatives have been, however, accompanied with very limited research studies to examine the role of utilized plants and their efficiency in the remediation process. This paper presents an overview of the status of these initiatives and phytoremediation potential in Lebanon.
