Figures & data

Table 1. Volatile compounds (aldehydes) of kids reared with milk replacer (MR) or natural milk from their dams (NM).

Table 2. Volatile compounds (aliphatic and aromatic hydrocarbons) of kids reared with milk replacer (MR) or natural milk from their dams (NM).

Table 3. Volatile compounds (ketones and alcohols) of kids reared with milk replacer (MR) or natural milk from their dams (NM).

Table 4. Volatile compounds (others) of kids reared with milk replacer (MR) or natural milk from their dams (NM).

Figure 1. Sensory analysis of meat from kids reared with milk replacers or natural milk. (a) Juiciness acceptability per age of consumer. (b) Overall acceptability per frequency of meat consumption. (c) Juiciness acceptability and overall acceptability of consumers who tasted the kid meat before the test (Yes/No). Rearing system x age of consumer test on juiciness acceptability, p = .028). Rearing system x frequency of consumption, p = .035. Rearing system x tasted the kid meat before the test on juiciness acceptability, p = .005. Rearing system x tasted the kid meat before the test on overall acceptability, p = .0003.
