The effect of sorghum varieties on digestibility and nitrogen balance of complete feed in goats

This study aimed to determine the effect of sorghum varieties (Brown Midrib Resistance and Super-2) on digestibility and nitrogen balance. Twelve female Bligon goats with an average body weight of 24.33±2.83 kg were divided into 3 groups of treatments with 4 replications, following a Completely Randomized Design (CRD) one-way pattern, T1 = complete feed based on fresh of Pennisetum purpureum as a control, T2 = complete feed based on silage of sorghum Brown Midrib Resistance (BMR), and T3 = complete feed based on silage of sorghum super-2. The observed parameters were nutrient feed intake, nutrient digestibility, and nitrogen balance. Data were processed using Statistical Package for the Social Sciences (SPSS) version 23. Data were analyzed by one-way of variance analysis and significantly different treatments, further tested with Duncan's New Multiple Range Tests (DMRT). The results showed that feeding use of a complete feed of sorghum BMR silage on Bligon goats reduced nutrient feed intake (P<0.05) compared to complete feed of sorghum super-2, while nutrient digestibility and nitrogen balance showed the same results for both sorghum varieties (P>0.05). Therefore we concluded that sorghum BMR was better than sorghum super-2. © 2021 Trans Tech Publications Ltd, Switzerland.
