Resumo
Toe trial was conduced at the Goiás Federal University (Goiás, Brazil) from January to December 1989. Four 12 to 18 month-old animais of gray race were kept in fenced area with Brachiaria decumbens pasture. Nutrition was supplemented by protein and energetic concentrate in order to supply nutrition requirement according to NRC. Seasons were detennined by variations on minimal temperature, pluvial precipitation and ralative humidity. The four seasons were: A (January, February and March), B (April, May and June), C (July, August and September) and D (October, November and December). Semen was collected by eletroejaculation and evaluated for volume, motility, concentration and morphology. Volume values for the four seasons were 0.91, 1.04, 1.07 and 0.96 mi respectively, with no significant difference between seasons (P=0.05). Spermatic concentration showed for seasons A, B, C and D the following values, respectively: 1201.5, 1018.2, 1161.2 and 1015.5 million/ml, with no significant difference. Motility was 80.25, 63.5, 76.6 and 73.75% for seasons A, B, C and D, being the average percentage 0.5, 0.5, 0.12 and 1.23, respectively. Results showed that the season with higher relative humidity was more hannful to ovine spermatogenesis and under suitable nutrition, seasonal change does not interfere on ovine fertility.
