<![CDATA[This research aims to identify the characteristics and production of fodder at different harvest times by establishing a hydroponic system to ensure a continuous supply of feed for dairy cows. The study comprises two phases. Phase I examines the production and nutrient quality of hydroponic fodder as a substitute for forage. This phase was conducted experimentally via a 2x3 factorial completely randomized design (CRD) design. Factor I = Plant type (maize and rice). Factor II = harvest time (7 days, 10 days, and 13 days). Phase II involves assessing the palatability of maize and rice plants as hydroponic fodder for dairy cattle. The data were analysed via a 2x2 factorial RAL design. Factor I = Plant type (maize and rice). Factor II = harvest time (10 days and 13 days). Maize and rice fodders harvested at various ages present the following characteristics: 1) As the harvest age increases (7, 10, and 13 days), the protein content of both maize and rice fodder increases, although overall production tends to decline after 10 days. The highest (fresh and DM) production occurs with maize fodder harvested at 10 days. 2) The elevated ADF and NDF contents in rice fodder up to 13 days result in lower dry matter digestibility (DMD) and organic matter digestibility (OMD) compared with those of maize fodder because of the presence of husks, which are the primary source of crude fibre. 3) Maize fodder is preferred by dairy cows owing to the number and size of its leaves and its vibrant green appearance.]]>
