Última Close relationship between pre- and post-calving reticuloruminal pH levels in dairy cows Organic Eprints Steinwidder, Andreas; Horn, Marco; Pister, Rupert; Rohrer, Hannes; Gasteiner, Johann. The aim of the present study was to investigate the effects of the prepartum reticuloruminal pH values on the postpartum pH values of lactating cows at two concentrate supplementation levels. An indwelling pH measurement system with a wireless data transmitting unit was given to 9 heifers and 11 cows orally 2 weeks before expected calving. pH was measured from week 2 prepartum to week 6 postpartum. Prepartum, all animals were fed hay and grass silage only. After parturition the animals were assigned to one of two concentrate supplementation levels (Con and Low). During the first 6 weeks postpartum, 5.6 kg and 2.9 kg dry matter (DM) per day of concentrates were fed to cows in groups Con and Low, respectively. Before parturition, no effect of the week on the... Tipo: Journal paper Palavras-chave: Feeding and growth; Health and welfare.
