In the table, 'Ratio' refers to the proportion of EDP supplemented to the feed, with divisions at 0.00 % and 2.50 %. 'Level' denotes the crude protein level in the feed, categorized into 16.00 %, 14.50 %, and 13.00 %. 'Ratio × Level' indicates the interaction between the supplementation ratio of EDP and the crude protein level of the feed. Within the same column, identical or absence of uppercase or lowercase letters signifies no significant difference (P > 0.05), different lowercase letters denote significant differences (P < 0.05), and different uppercase letters indicate highly significant differences (P < 0.01). The same notation applies to the following tables."
