Abstract
- Abstract: A digestibility trial was conducted with 180 Nile tilapia (32.65 ± 4.52 g) fed a reference diet containing 350 g/kg crude protein and 4,500 kcal/kg gross energy. Five different meat and bone meals (MBMs) were evaluated. The test diets compound by 70% of reference diet and 30% of each MBM were elaborated and classified according to ash content: MBM‐430, MBM‐400, MBM‐370, MBM‐340 and MBM‐310. The apparent availability coefficient (AAC) of minerals and the apparent digestibility coefficient (ADC) of dry matter (DM) were subjected to one‐way analysis of variance (<italic>p</italic> < .05). Differences among ADC and AAC were determined by Tukey's multiple range test (<italic>p</italic> < .05). When appropriate, a polynomial regression analysis was performed. Linear correlation analyses between MBM chemical composition and the AAC and ADC were performed (<italic>p</italic> < .01). Higher values of ADC<subscript>DM</subscript>, AAC<subscript>C</subscript><subscript>a</subscript> and AAC<subscript>P</subscript> were observed in MBM‐310, while low values were observed in MBM‐430. Quadratic effects of ash, P and Ca contents on AAC<subscript>C</subscript><subscript>a</subscript>, AAC<subscript>P</subscript> and ADC<subscript>DM</subscript> were observed. The AAC<subscript>C</subscript><subscript>a</subscript>, AAC<subscript>P</subscript> and ADC<subscript>DM</subscript> indicated a negative correlation with ash, P and Ca contents. MBM‐310 exhibited the highest mineral AAC, which could be used as a mineral source for Nile tilapia. [ABSTRACT FROM AUTHOR]
