Abstract | This study aims to investigate the effects of using dried and ground Mexican kale leaves in tilapia feed. A completely randomized design (CRD) was planned for the study with four treatments. The study investigated fish feeding patterns for Nile tilapia (Oreochromis niloticus) with an average starting weight of 0.893?0.141 g, an initial length of 2.784?0.367 cm, and an initial body width of 0.834?0.186 cm were raised in 12 cement ponds with a water capacity of 1 x 2 x 0.8 meters at a density of 50 fish/pond for 12 weeks. The feed contained a percentage of 0 (T1; control), 9 (T2), 14 (T3), and 19 (T4) dried and ground Mexican kale leaves at the local research center in Ban Tad from May to July 2023. It was determined that the T2 feed had a specific growth rate in weight of 5.824?0.291 for tilapia, which was comparable to the T3 feed (5.827?0.199, P>0.05) but substantially higher than the control feed (T1, 5.638 ? 0.174) and T4 (5.557?0.210) (P<0.05). The survival rate of tilapia fed with T2 feed was the highest at 84.443?1.928, followed by T3, T1, and T4 at 83.333?3.335, 83.333?3.335, and 83.110?3.006, respectively (P > 0.05). The feed conversion ratio (FCR) was the lowest at 1.196?0.050, and the cost of feed ingredients was the lowest at 45.32 Baht/kg. This indicates that using a percentage of 14 dried and ground Mexican kale leaves in tilapia feed resulted in the best growth without affecting the survival rate and FCR. |
