In a tropical ranch of animal production, which was divided by fire lines into 20 equal grazing paddocks of one mile square each, a grazing experiment was conducted as controlled rotational grazing with forty-five (45) cross-bred Sudanese improved Baggara cattle which were divided into four feeding systems (groups). A drop in condition scores of the farm cattle stock herd was treated during dry summer by supplementary feeding with four types of supplements to investigate the changes in average body weight changes, heart girth and condition scores, through dry summer, wet summer and winter seasons. The results showed that, animals of group three (G3) which supplemented with groundnut cake performed better in all body parameters under study when compared with group one (G1) and group two (G2) being supplemented with groundnut haulm, Stover respectively and group four (G4) which was kept under natural grazing as control group (Natural grazing alone) which reveals the worse body measurement traits performance under study. The effect of seasonal changes showed a significant difference (P haulm (in dry and wet summer -143.60 Kg and 163.50 Kg respectively), Stover supplements and natural grazing (controlled) groups. The results also showed that, the heart girth and condition score were significantly different (P < 0.05) between the treatments in wet summer and winter. While showing no significant difference between the treatments in dry summer, group supplemented with groundnut cake during the dry summer reported better performance in condition scores than other groups.
