The objectives of the study were to determine the effects of varying levels (%) (0, 5, 10, and 15) of spiny amaranth leaves in the diet of Sasso broilers, a free-range type of chicken. Further, the proximate composition of diets, growth production and carcass quality parameters, and intestinal morphology were assessed in a feeding trial. A total of 120 Sasso broilers were randomly assigned in four treatments following Completely Randomized Design (CRD); each treatment had three replications with 10 Sasso broilers per replicate. The experimental treatments were without spiny amaranth, with 5% spiny amaranth, 10% spiny amaranth, and with 15% spiny amaranth. When expressed on a dry matter (DM) basis, spiny amaranth contained 89.00% DM, 20.20% crude protein, 10.80% crude fiber, 0.70% crude fat, and 16.50% ash. Intestinal morphology was evaluated with the use of a stereomicroscope equipped with a micrometer (mm) as a measuring unit and set to scanner magnification and low power objective (LPO) magnification. Gain in weight and carcass quality of Sasso broilers during the seven weeks was not influenced (P > 0.05) by spiny amaranth feeding. However, under scanner magnification setting, the intestinal morphology of Sasso broilers supplemented with 15% spiny amaranth had a numerically greater measurement of the duodenum (105mm) and jejunum’s (130mm) villi while Sasso broilers fed 5% spiny amaranth attained greater width of ileum’s (65mm) villi than their counterparts. Numerically, measurement in width of villi for Sasso broilers fed 10% spiny amaranth leads with 11mm among treatments. The results showed that spiny amaranth leaves as a supplement in the ration of Sasso broilers merit consideration.
