Outline of Final Research Achievements

This study analyzed feeding management technology directly linked to the fertility of cattle from the viewpoint of feeding and nutrition. We investigated the influence of feeding and nutritional status of dairy cattle on reproductive function and found that lactation itself does not have a negative influence on ovarian function. In addition, the number of follicles growing in the ovaries tended to increase with intermittent high nutritional feeding treatments we devised. Furthermore, we successfully detected the nutritional status of calves after delivery and the extent of disappearance of intrauterine bacterial contamination with high sensitivity.
