Résumé

The aim of the study was to assess and classify the quality of semen from Balami, Uda and Yankasa breeds of sheep fed Brachiaria decumbens or Digitaria smutsii supplemented hay. Thirty rams, 10 each of Balami, Uda and Yankasa breeds aged 18 months and weighing 24.75, 25.50 and 25.50 kg, accordingly were used. All semen quality traits were influenced by genotype and hay type. Semen taken from rams fed Digtaria smutsii had higher number of live spermatozoa and lower number of abnormal spermatozoa than those fed Brachiaria decumbens hay. Balami rams were superior for semen volume and concentration while Uda rams were superior in normal and live spermatozoa percentage. There was interaction between breed and hay type in most of the traits where rams on D. smutsii hay had higher values than those on B. decumbens. It was therefore, concluded that variation in some semen characteristic of indigenous breeds of sheep was both breed and feed inclined. Hence it is recommended that farmers feed their animals quality forages to improve their reproductive performance.
