Abstract
Diets containing progressively higher levels of instant coffee residue (ICR) (from 0 to 15% in 3% increments) were given for 11 days to 8-day-old chicks and turkey poults. A total collection of faeces was carried out for the last 4 days of the trial. Preliminary performance data indicated that liveweight gain (LWG), food intake (FI) and food conversion ratio (FCR) all deteriorated with progressively higher levels of ICR, although the decline was less evident in turkey poults. Values obtained for apparent metabolisable energy of ICR (fresh weight basis) were 2.36 and 9.94 MJ kg −1 for broiler chicks and turkey poults, respectively, and although data for ether extract digestibility and nitrogen retention confirmed this species difference, there was no effect of species on acid detergent fibre digestibility. It was concluded that there is potential for the use of ICR in turkey diets providing problems of odour and texture can be overcome.
