Abstract: | The number of birth per year was an important indicator of the sow's productivity and it was related to the duration of breastfeeding.Weaning had been shown to be a stressful period.The weaning age had declined over time in order to increase sow productivity and the fact that weaning under modem-day commercial conditions inflicted stress (environmental,nutritional and psychological/social) on pigs and associated with marked changes in gastrointestinal tract (GIT) physiology,microbiology and immunology.However,the early weaning resulted in post-weaning diarrhea,mainly related to intestinal dysbiosis during this rapid adaptation to the new diet.The environment and feed had influence on physiology,gut morphology,immune system and diseases of weaned piglets. |
