- 1. The growth of wild water lentils (duckweed) in Jordan’s farm irrigation ponds has focused attention on the need to study the functions of these plants as a natural water bioremediation agent and as a potential protein source for broilers. This paper examined the water source and water quality (nutrient composition) of irrigation ponds that support duckweed plants and their suitability as broilers feed. The results showed that the source of the irrigation ponds is Zarqa River, and the analyzed water quality parameters of the source fall within the allowed limits set forth in the Jordanian Standard. The growth of duckweed in farm irrigation ponds reduces the nutrient supply to irrigated crops and serves as a purifier of irrigation water. These plants remove an average of 20% Ca, 33% Mg, 21% K, 13% Cl, 25% SO4, 35% PO4, 1.5% Na, and 40% NO3. Fresh duckweed contains approximately 94% water and 6% dry matter; the average nutrient concentrations in dry matter are 26% protein, 4.16 % N, 5.2% fiber, 3.1% fat, 0.86% P, 2.4% K, 4.3% Ca, 0.88% Mg, 0.2% Fe, 1.62% Cl, 0.16% Na, 0.008% Zn, 0.07% Mn and 0.002% Cu. This research reveals the potential for Jordan to examine the availability of duckweed in farm irrigation ponds and their function as water bioremediation agents and their suitability as a protein and nutrient source for broilers. If harvested at frequent intervals and dried, water lentil plant (duckweed) could be of great benefit to Jordan's livestock sector, especially with regard to poultry, where feedstuffs are limited in supply and prices are typically high. https://www.sciencedirect.com/science/article/abs/pii/S0925857415300598
2. 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.
