Effect of dietary conjugated linoleic acid on serum levels of N2O5 and L-citrulline in goat kids

Abstract

Forty new born male kids were allotted into two groups for the evaluation of the effects of dietary conjugated linoleic acid (CLA) on nitric oxide (NO) and l-citrulline levels in serum. The control group received no supplement CLA and the CLA group received 20 g/kg milk DM of CLA from birth to 1-month old. The kids were fed colostrum for 2 days and milk replacer from days 3 to 29. Blood samples (n = 40) were taken at 1, 8, 15, 22, and 29 days of age. N2O5 (nitrite + nitrate) concentration in serum ranged from 21.93 to 26.15 and 34.90 to 40.59 μmol in control and CLA kids. The l-citrulline values ranged from 0.30 to 0.40 and 15.54 to 19.81 μmol in control and CLA kids. © 2005 Elsevier B.V. All rights reserved.
