Acute effects of rotavirus and malnutrition on intestinal barrier function in neonatal piglets

Table 1 Jejunal lactase activity and morphology of piglets fed full-strength formula (fully fed) or half-strength formula (malnourished) and infected or non-infected with rotavirus

	Fully fed		Malnourished
	Non-infected	Infected	Non-infected	Infected	SE	Effect1
Lactase activity [mmol/(min∙g protein)]	169.8	9.6	160.3	19.7	21.0	V
Intestinal morphology
Villus height (mm)	0.87	0.37	0.85	0.34	0.13	V
Crypt depth (mm)	0.10	0.13	0.13	0.16	0.01	V, F
Height:depth ratio	8.96	3.12	6.86	2.12	1.24	V

Values are least-square means for n = 6 pigs per group, measured 3 d post-inoculation.

¹V, main effect (P < 0.05) of rotavirus infection; F, main effect (P < 0.05) of feeding level; Interaction of rotavirus and feeding level (V, F) was not detected (P > 0.05).
