Abstract

The necessity for enhancing goat intake and performance, particularly in cases where they exhibit selectivity towards non-palatable and unconventional feed ingredients during feeding, led to the adoption of pelleting techniques. A study was undertaken employing sixteen growing West African Dwarf (WAD) goats in a complete randomized design to assess the impact of pelleting on the efficient utilization of rice bran in pelleted diets. Grinded dry cassava peel (GDCP) was substituted by rice bran (Rb) in diets 1 through 4 at levels of 0%, 15%, 25%, and 35%, respectively. The consumption of Rb increased significantly (p<0.05) as GDCP was replaced. While there was no significant change in total feed intake (p>0.05), total weight gain increased (p>0.05) from 0.34 to 1.18 kg, as did the feed conversion ratio (p>0.05). Goats on Diet 4 exhibited the highest feed conversion ratio (12.97%). The nutrient digestibility of the diets showed a significant increase (p<0.05) in crude protein (CP) and nitrogen-free extract (NFE) as the proportion of rice bran in the diet increased. Across all criteria pertaining to carcass characteristics (fasted live weight, carcass weight, dressed weights, dressing percentage, and whole or pieces), the results were comparable (p>0.05). The high feed conversion efficiency, elevated digestibility coefficient CP level, and comparable value (p>0.05) of different carcass parts at 35% replacement of GDCP with Rb affirmed the efficacy of pelleting methods for incorporating non-palatable and unconventional feed materials alongside other feedstuffs for goats, without selective feeding behavior.
