- 1. Duckweed plants have been seen to grow naturally in Jordan’s irrigation ponds. Their massive reproductive capacity causes the formation of a dense cover of these plants, and raises the attention towards studying their functions as a natural water purifying agent, and as a feed source for laying hens. Therefore, this paper examined the average percentages of nutrients’ removal by duckweed, and the production performance of laying hens. The results showed that the growth of
duckweed in irrigation ponds serves as a purifier for 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. The analysis of the water source in irrigation ponds showed that the heavy metals (Zn, Cd, Pb, and Cu), are within Ideal Detection Limits. The analyzed duckweed samples contain 26% protein, 2913 Kcal/Kg metabolizable energy, 5.2 fiber, 3.1% fat, 4.3% Ca and 0.86% P. A feeding trial was conducted onlaying hens by replacing part of soybean with percentage of duckweed, and proved its efficiency on laying hens egg production. The results highlight the importance of this research to undergo further studies as to the utilization of these plants as a water purifier, and as the future promising feed source for livestock sector.

2. 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.
