Item type:Publication, Effects of partial substitution of feed with spent coffee grounds on growth performance and carcass quality in broilers(2024-03-01); The research findings found that the spent coffee grounds (SCG) substitution with 5% and 10% in feed (SCG-5 and SCG-10) which exhibited significant (P<0.01) effect on average daily gain with 80.82 and 66.84 g/day as compared to 0% substitution (SCG-0), which 88.62 g/day. While the the affecting on feed conversion ratio was shown in SCG-10 (2.05), which significantly (P<0.01) higher than SCG-5 (1.78) and SCG-0 (1.73). Similar to the carcass quality, SCG-10 was significantly (P<0.01) exhibited lower carcass weight (2,023.38 g) than SCG-5 and SCG-0 (2,267.48 and 2,319.70, respectively). However, there was no significant difference in the percentage of the carcass. Furthermore, substituting SCG in the feed had no impact on the weight of major muscles, such as the breast and thigh muscles. The inclusion of SCG-10 and SCG-5 was significantly increased in liver weight (P<0.05). However, only a high substitution rate of 10% SCG was significantly decreased in abdominal fat (P<0.01) as compared to the inclusion levels of 5% and 0% in the feed. In conclusion, substituting 5% SCG into the feed had shown to be a marginal impact on production efficiency, while a 10% SCG substitution rate distinctly influenced both production efficiency and carcass quality.
