^a,bValues with different letters in a row differ significantly, P < 0.05.

^AGroups II, III, IV, V were fed with halloysite and zeolite (1:3 ratio) at 0,5% (1–35 days) and 1% (36–42 days) level. Aluminosilicates were also used for the litter: II—500 g of halloysite/m²; III—250 g of halloysite/m² and 250 g of zeolite/m²; IV—500 g of zeolite/m²; V—130 g of halloysite/m², 370 g zeolite/m².
