| Popis: | The present study aimed to examine the effects of dietary L-carnitine supplementation on performance parameters and egg quality measurements of white Leghorn hens at two dietary fat levels. Two hundred 22-weeks old white Leghorn hens were randomly distributed into 40 cages of five birds each. Two basal diets different in added fat level (0 or 3%) were formulated and supplemented with incremental levels of L-carnitine (0, 50, 100, 150 mg/kg diet). The experiment lasted 98 d (two weeks for adaptation and 12 weeks as the main experimental period). At the final day of trial, ten randomly selected hens per treatment were euthanized to measure abdominal fat content. Dietary inclusion of 3% soybean oil caused a significant (P |
