    Student thesis: Master's Thesis


    This study has been carried out to analyze the feasibility of locally grown seaweed as a source of protein to become potential animal feed alternative for local cattle to contribute to food security in UAE. The author will study the digestibility, minerals contents, and protein content of Ulva and Padina, two locally grown seaweed species, and compare with commercial seaweed; Brown Canadian seaweed (Tasco). In addition, Super Pro designer software is utilized to conduct economical evaluation of seaweed farming and its profitability as per the world market. Sun drying and tray drying options are compared to select the best suitable option in the context of UAE. The results conclude that local seaweed is competitive and could be an alternative for animal feed at small scale or as a supplement. Ulva is the best candidate for animal feed considering it is high in protein, low in ADF and NDF, in addition to the fact that it is abundant in Abu Dhabi and it contains plenty of minerals, such as Calcium, Iron, and trace elements. It was also found that sun drying method is the optimal method when compared to tray drying in the context of animal feed as the payback period for the sun drying method is found to be 3.93 years while the payback period for the tray drying method is found to be 4.46 years. In addition, as the plant size and farm size increases, the cost of farming and payback period decreases.
