This study investigated the effect of cotton seedcake as a protein supplement on the growth performance of the Small East African Zebu weaner cattle. The study was conducted at KARI-Kiboko in Makindu District, Makueni County, Kenya. The animals were allocated randomly to feeding treatments in individual pens. A basal diet of Chloris gayana (Rhodes grass) hay was given to the animals so that each animal could get access to it ad libitum in its individual pen. The animals were then subjected to the treatments for an acclimatization period of 14 days. During this period estimated amount of basal diet consumed per animal per day was determined. Immediately after this, data collection commenced. Feed intake was determined by recording the amount of hay given in the morning which was slightly above the amount as determined during the acclimatization period and left over weighed the following morning. Consequently the amount consumed was the difference between the amount offered and the amount leftover. The left over were weighed the following morning just before the amount for that day was offered so as to determine the amount consumed per day. The treatments comprised of control (no supplementation), 300 g and 500 g cotton seedcake per animal per day. Mineral lick and water were provided ad libitum. The feeds used were analysed to determine their chemical composition and feed value. It was clear from the results that cotton seedcake was higher in CP (five-fold), EE (four-fold) and ME (two-fold) than the control diet. Data on live weight and feed intake were analyzed using General Linear Model of Statistical Analysis System. The results of the data analysis showed increased (P<0.05) feed intake in that the amount of hay consumed increased with the increase in the amount of supplement. Live weight gain also increased (P<0.05) with the increase in the level of supplementation.
