Effects of sward type and concentrate feed level on the performance of spring-calving grazing dairy cows on a wetland soil type

Year: 2026

Type: article

Abstract: , respectively). No interaction between SS and CF for milk production parameters were observed. Neither CF nor SS had a significant effect on reproductive performance. Mean submission rate, pregnancy rate to first insemination, pregnancy rate to second insemination, pregnancy rate in the first 42 d of the breeding period, and in-calf rate were 96%, 42%, 27%, 64%, and 88%, respectively for all farmlets. The results of this study highlight the possibility to reduce chemical fertilizer N and feed input requirements and maintain animal performance within pasture-based systems on wetland soils.
