[Value of an antiparasitic treatment against Strongyloidea and Coccidia in Djallonke ewes at lambing].
Three groups of 14 Djallonke ewes each have been compared: group E received one antiparasitic treatment with Ivermectin, or Valbazen and Amprol at lambing, group T2 received three classical antiparasitic treatments with the same drugs according to the seasons (at the beginning and at the end of the long rainy season, and at the end of the short rainy season) group T1 remained untreated. The onset of sexual activity occurred 71.5 +/- 5.4 days (lot E), 74.5 +/- 6.3 (lot T2) and 104.3 +/- 10.3 (lot T1) after lambing. So, intervals between lambings were 255.7 +/- 11.8 (lot E), 245.9 +/- 13.5 (lot T2) and 298.2 +/- 24 (lot T1). Lambing other characteristics were almost the same in the three groups: prolificacy 127-137%, weight at birth 1.2-1.4 kg, daily weight gains (0-90 days) 99-114 g and mortality 39-48%. It seems economically more profitable to treat against internal parasites once at lambing rather than three times a year according to the seasons.
