Keywords: pH, microbes, rumen, soybean milk residue, NH3-N, volatile fatty acids

In this study, 25 weaned bucks weighing 8.40kg were used to evaluate rumen kinetics (rumen pH, bacteria, fungi, protozoa, NH3-N production and volatile fatty acids production) of Red Sokoto bucks at 30, 60 and 90 days of feeding diets containing varying levels of soybean milk residue as a replacement for soybean meal. The diets were designated T1, T2, T3, T4, and T5. The Red Sokoto goats were fed diets containing varying levels of soybean milk residue with Ficus lyrata as a basal diet at 30, 60 and 90 days of the experiment. Complete Randomized Design (CRD) was used in this experiment. Rumen pH did not change significantly throughout the experiment but fluctuated around 6.03 and 6.56. NH3-N production in the rumen reduced at 60 days but picked up at 90 days. Volatile fatty acids also maintained a similar production profile throughout the experiment. Protozoa, fungi and bacteria counts reduced at 60 days but increased at 90 days. Protozoa counts were highest for bucks receiving diets containing 100% soybean milk residue throughout the experiment. Fungi count was highest in T3 (28.03) for buck receiving diets containing 50% soybean milk residue at 30 days and T2 (21.46) for buck receiving diets containing 25% soybean milk residue at 90 days. The least bacteria count was recorded in T4 (9.61) for buck receiving diets containing 75% soybean milk residue at 30 days. The highest bacteria count was recorded in T5 (41.16) for buck receiving diets containing 100% soybean milk residue at 90 days. Soybean milk residue supplementation did not cause any disruption in the rumen ecology.
