WAYS OF CONDUCTING PUERPERIUM IN SOWS PUBLISHEDCornelia Petroman, Ioan Petroman, Horea Sărăndan None
In the conditions of raising animals on farms with a high degree of artificiality and mechanisation, the evolution of the puerperium influences the increase of the fecundity and birth rate percentage and results in an increase of the duration of exploitation of sows. This evolution depends on the hypothalamus-hypophysis hormonal complex that, during the first post-partum days, secretes gonadotropic hormones that trigger ovary activity. The earlier the ovary activity, the earlier the uterus involution, degradation and eviction of secretions, and the morphological and functional recovery of the endometrium are. Ovary activity in sows in puerperium is characterised by a substantial diminution of the size of yellow gestation bodies during the first 7 post-partum days and the turning of the red colour in the first day into dark brown and, towards the end, into mother-of-pearl white.
