Duckweed as a Feed Ingredient in Laying Hen Diets and its Effect on Egg Production and Composition

Bacterial fermentation of Lemna sp. as a potential substitute of fish meal in shrimp diets

“…On the other hand, the crude protein found in unfermented Lemna sp. was higher than that found by Cruz et al (2011) (15.7%) and Yilmaz et al (2004) (18.4%) in unfermented flour of L. minor; however, it was lower when compared with unfermented L. minor studied by Oludayo-Olaniyi and Omoniyi-Oladunjoye (2012) (42.2%), and with S. polyrrhiza (29.05%) (Anderson et al, 2011). Although there were not significant differences between fermented and unfermented flour on crude protein content, the observed decrement in fermented flour might be due to possible metabolic utilization by P. pentosaceus and B. pumilus, which hydrolyze protein from plants to equilibrate the C:N ratio, since molasses has low protein content (4%) and higher (50%) carbohydrate content (Cleasby, 1963).…”

Feeding Diets Containing Different Forms of Duckweed on Productive Performance and Egg Quality of Ducks

“…Lysine content of duckweed as an animal feed also met the standard recommended by FAO and it is generally higher than that found in grain (Cheng & Stomp, 2009). Feeding duckweed has been studied in broiler chickens (Syamsuhaidi, 1997;Kabir et al, 2005), native chickens (Khang & Ogle, 2004;Thuy & Ogle, 2007), laying hens (Anderson et al, 2011), breeding ducks (Men et al, 2001a), growing ducks (Men et al, 2001b), and in laying ducks (Tamsil & Indarsih, 2003;Khandaker et al, 2007).…”

“…The low level of β-carotene in the diet, due to the low content of yellow corn, is the main cause of low egg yolk pigmentation. The use of duckweed, a potential local feedstuff with low price, is one alternative to overcome the problem, because it contains high β-carotene (111.24 mg/kg dry matter) and crude protein (29.05%) (Anderson et al, 2011) and it can be cultivated to produce high biomass (Cheng & Stomp, 2009).…”

After the genome sequencing of duckweed – how to proceed with research on the fastest growing angiosperm?

“…This has the effect of cleaning wastewater (Zhao et al 2015 and references therein), and contrasts with the effect of modern agriculture, which results in eutrophication because of the use of high amounts of fertilisers. Under optimal growth conditions, duckweed plants have a high protein content (Cheng & Stomp 2009;Anderson et al 2011), making them valuable as food for animals and even for human consumption (Landolt & Kandeler 1987;Anderson et al 2011;Xu & Shen 2011). Alternatively, reduced growth conditions result in a decrease in the protein content but high accumulation of starch (Sree & Appenroth 2014), which can then be used for bioethanol or butanol production (Cui & Cheng 2015).…”
