Samples were collected (AV) each week (1 ej./!j‘/week) for 2 years (1977, 1978) from 5 adult IF rams of different genetic origins, registered in a flock book. The animals were always kept in a sheepfold. They all received the same feeddult IF rams of different genetic origins, registered in a flock book. The animals were always kept in a sheepfold. They all received the same feed. Semen morphology and massal motility were determined for each ejaculate. The percentage of abnormal cells was established by counting 150 cells per smear (1 smear/a’/week ; eosin-nigrosin staining). The criteria for celle abnormality were : abnormal head (TA), no tail (SD), proximal droplets (GCP), distal droplets (GCD), abnormal tail (AF). High ambient temperatures in the shade were recorded during the summer months to study their ultimate effect on semen quality. Ejaculations were obtained for 2 whole years from all the rams. The main results were as follows. 1. - On the whole, morphological abnormalities (MA) were more frequent from January to June than from July to December : 16.5 ! 0.9 vs 13.9 ! 0.8 p. 100 (P > 0.05) and 25.3 ! 1.0 vs 17.3 ! 0.9 p. 100 (P < 0.01) for 1977 and 1978, respectively. The profiles of these abnormalities and their 6-month mean were not very different for the 2 years, except for AF which was nearly always higher in 1978 than in 1977. The ejaculation usually contained a yearly maximum of abnormal cells from midFebruary up to the end of May (1977 and 1978), indicating that semen quality in this breed closely depends upon the photoperiod. The maximum points occurred generally in March (4 rams out of 5) but large individual differences between the values were observed (28 to 66 p. 100 of MA in 1977 ; 32.7 to 70.7 in 1978). The length of time during which the proportion of MA was high (> 20 p. 100) varied considerably with the ram (4 to 16 weeks in 1977, 6 to 17 weeks in 1979). Those differences in animals showed a low or high sensitivity to the increasing photoperiod. In autumn, on the contrary, the morphological curves were close. An estimate of the reproductive capacity of a sire, based upon morphological examination of the sperm, should thus be made in the spring.
