The effects of digestible threonine levels, based on ideal protein concept in diets with 1.35% of digestible lysine on Nile tilapia (Oreochromis niloticus) fingerlings performance. Four hundred thirty two reverted Nile tilapia, Thailand strain, with initial weight of 1.64 ± 0.03 g, were allotted to completely randomized design, with six diets and six replications with twelve fishes each. The five diets, isoenergetic isoproteic, consisted of various threonine:digestible lysine ratio (69.0, 74.0, 79.0, 84.0, and 89.0%) and methionine + cystine:digestible lysine […]

This trial was conducted to evaluate the dietary levels of digestible threonine for growing gilts on heat stress environment. Seventy crossbreed gilts averaging initial weight of 14.9 ± 0.56 kg were assigned to a complete randomized blocks design with five treatments (levels of digestible threonine) of seven replications (two animals per experimental unity). The treatments consisted of the following dietary digestible threonine levels: 0.538, 0.577, 0.614, 0.651, and 0.688%. Daily weight gain and threonine intake linearly increased as the dietary […]
