Some aspects of the puerperium after singleton and twin parturitions in Santa Inês ewes submitted to energy restriction during pregnancy

摘要: Abstract The present work aimed to characterize the uterine involution after singleton and twin parturitions in Santa Ines ewes submitted two nutritional diets. Sixteen pregnant pluriparous ewes, with age ranging from 3 5 years, were used. animals randomized into four experimental groups of each. experiment was a 2 × 2 factorial number lambs (singleton versus pregnancy) diet (maintenance maintenance 15% energy deficit). To determinate fetuses, all an ultrasonographic evaluation at days 30, checked 45 60 pregnancy. Genital tract followed by vaginal smear cytology transrectal uterus ultrasonography. Changes cells wall not useful process genital however leukocyte were. Ultrasonographic observations pointed longer period for reduction stabilization size parturition, there no alteration due level restriction.
