| Carnitine is an amino acid regulatory and is important in the metabolism of long-chain fatty acids in the ß - oxidation, and it is important in the organization of the work of the blood brain barrier, and is very important in the treatment of infertility and sexual apathy. This study was conducted at the Poultry Farm of Department of Animal Resource, College of Agriculture, University of Baghdad during the period from 15 / 2 / 2011 to 1 / 8 / 2011. The aim of this study was to investigate the effect of dietary supplementation with different levels of carnitine on semen characteristics of guinea fowl males. A total of 24 guinea fowl male, 30 weeks of old were used in this study. Birds were randomly distributed into 4 treatment groups (C0, C100, C200, C300) which is carnitine was added to the diets at levels 0, 100, 200, 300 mg / kg of diet, respectively. Birds were fed during the whole period of birds rearing which lasted 22 weeks on diet contain 17.77 % crude protein and 2933.8 Kcal metabolic energy / Kg. L-carnitine was added to the diets of birds at the beginning of 34 weeks of birds age till the end of experiment which lasted 18 weeks including 2 weeks which considered as preliminary carnitine treatment period. Guinea fowl males were reared during experimental period in separated cages. Results showed that adding L-carnitine to the diet of guinea fowl males resulted in significant increase (P<0.01) with relation to ejaculate volume, mass activity, Individual motility, sperm concentration, percentages of dead and abnormal spermatozoa, spermatocrit, acrosomal abnormalities and semen quality factor. In conclusion the supplementation of L-carnitine to the diets of guinea fowl males resulted in significant improvement in semen quality traits of guinea fowl males. Therefore, L-carnitine can be used as an important feed additive for improve reproductive performance of bird males. | ||
