Performance of pacu (Colossoma macropomum) fed varying dietary inclusion levels of fish visceral and duckweed (Lemna minor) as replacement for fish and soybean meals
(2024-01-23)
The performance of Colossoma macropomum subjected to a six-month feeding trial using duckweed (Lemna minor) and fish visceral as partial replacements for soybean meal and fishmeal respectively was evaluated in this study. A total of one thousand five hundred (1500) nearly same sizes (average size 45 g) juveniles of C. macropomum were sourced from the nearby research man-made lake and subjected to proper acclimatisation for two weeks prior to the commencement of the feeding trial. One hundred (100) juveniles per ...

Influence of season and phytochemicals on the elemental composition of kobs’ diets in Old Oyo National Park, Nigeria
(2024-02-20)
Phytochemicals or plant secondary metabolites (PSMs) are known to counteract mineral nutrients (MNs) utilisation in herbivorous wildlife, yet studies on the interactions between PSMs and MNs in relation to herbivory, particularly for kobs (Kobus kob) are scarce. Composite samples of each of five major forage plants of kobs’ (Grewia mollis, Afzelia africana, Gardenia aqualla, Maranthes polyandra and Andropogon gayanus) were randomly collected in and around feeding sites of kobs in both dry and wet season. Using standard ...
