Evaluation of the Effects of Melatonin Implants on Testicular and Spermatic Parameters of Rams Raised in Station in the Niayes Zone in Senegal

The intensification of livestock production in response to the growing demand for animal products is increasingly creating new challenges terms control management and feeding, especially reproduction. Also, ewes are often considered responsible infertility problems a sheep flock, as reproductive capacity rams taken granted. However, it important have genetically superior males improve overall fertility herd. And, one way sexual performance their fertilizing capacity, them undergo melatonin treatment. objective this study was evaluate effects use implants on testicular spermatic parameters raised stations Niayes area Senegal. experimental herd consisted 6 well-known body characteristics which were followed 2 months during measurements carried out at beginning semen collected by electroejaculation every weeks. After break weeks, same implanted with (MELOVINE ®) rate 3 implants/ram, i.e. dose 54 mg per ram, collections again months. Data antero-posterior diameter, weight, scrotal circumference, analysis (volume, color, appearance, mass individual motility, concentration, morphology) recorded processed Excel exported SPSS software where they subjected descriptive statistical independent sample comparison testing. results showed that treatment significantly reduced weight (555±155 g vs. 396±128 g) diameter (23.42±2.0 cm 20.10±2.26 cm). induced improvements ejaculate volume, sperm production, morphological abnormality rate, and, most significantly, motility (2.1±1.5 3.3±1.2) survival (54±34% 80±31%) spermatozoa. Melatonin has therefore improved rams, an interesting tool improving productivity farms. It can be recommended artificial insemination centres order doses produced.
