Evaluation of Physicochemical Properties and Sensory Qualities of Raw Milk Collected from Lactating Cows Fed on Different Level of Peanut Meal

Abstract

The study was conducted to evaluate the feeding value of Peanut Meal (PM) with concentrate feeds on milk physical quality and milk composition. Changeover design was used in three periods each comprising 25 days plus the first seven days for adaptation and ten days for wash out residual effect between consecutive periods. Treatment diet was PM while Soya Bean Meal (SBM) was used as control leveled at a ratio of 100PM: 0SBM (T1), 50PM: 50SBM (T2) and 0PM: 100SBM (T3). The basal diets were maize, wheat bran, minerals and vitamin premix while grass hay and corn silage were fed ad libitum. Results of analysis of chemical composition of milk shows that there was highly significant difference (P<0.05) in milk fat due to treatments and stages of lactation (3.52, 3.59 and 3.65) for T1, T2, T3 and (3.58). The CP% of milk was different among treatments (3.6, 3.61 and 3.63 of T1, T2 and T3, respectively. Result of Sensory evaluation of milk showed significant difference only in color. Generally, the experiment showed that replacement of peanut meal for soybean meal has improved the milk qualities. Therefore, I recommend peanut meal for dairy producer to use as a supplement.
