Abstract

Ross × Ross 708 eggs were injected with commercial diluent containing supplemental L-carnitine at 8, 16, or 32 mg/100 μL concentrations using an automated multi-egg injector. After hatching, 1,080 male and female broiler chicks were distributed into 90 pens with chicks at each of the injected concentrations receiving feed that was or was not supplemented with 50 ppm of L-carnitine. Treatments did not affect incubation time or hatchability of fertilized eggs. Birds fed supplemental L-carnitine and injected in ovo with L-carnitine had lower body weight and ate less feed. The same birds exhibited a reduction in feed conversion compared to birds that did not receive supplemental dietary L-carnitine. Absolute breast weight was reduced in birds given L-carnitine in ovo and in the feed. Broiler diets containing 50 ppm L-carnitine appeared to be slightly toxic if provided with 8, 16, or 32 mg/100 μL of L-carnitine administered via in ovo injection.
