Abstract

The study investigated the effect of chop length of wheat straw in a high-straw dry cow diet on the feeding behavior, health, and performance of Holstein dairy cows across the transition period. Forty cows were enrolled at dry off, approximately 45 d before expected calving, and assigned to 1 of 2...

Abstract

The objective of this study was to determine the effects of adding molasses-based liquid feed to a high-straw dry cow diet on intake, behavior, health, and performance of dairy cows across the transition period. Holstein cows (n = 40) entering their second lactation or greater were enrolled at ...

Abstract

This study (1) investigated the effect of dietary transition at dry off on the behavior and physiology of Holstein dairy cows and (2) evaluated the efficacy of utilizing reductions in dietary nutrient density and milking frequency to mediate the dry-off process. Forty-eight cows were dried off over ...

Abstract

The effects of high stocking density during the dry period on dairy cow physiology, behaviour and welfare were investigated. Holstein Friesian cows (n=48, calving over a seven month period) were dried-off 60±4 d before their expected calving date, and allocated to either high (H) or low (L)...

Abstract

The present study investigated the effect of straw yard housing during the dry period and 2 d of additional maternity pen housing postcalving on lying and feeding behavior and calving difficulty in Holstein dairy cows. In this study, 122 multiparous cows were moved to either a straw yard or into...

Abstract

The objective of this study was to determine the effect of adding water to a high-straw dry cow diet on feeding behavior, health, and performance of dairy cows. Holstein cows (n=40) entering their second or greater lactation were enrolled at dry off (∼45 d before expected calving) and assigned to 1 ...

Abstract

Background: In seasonal, pasture-based, dairy production systems, cows must recover from calving and become pregnant within two to 3 months. To achieve this, the uterus must involute and ovulation must occur and continue at regular intervals. As these processes are affected by the cows' nutritional ...

Abstract

A widespread management practice in commercial dairy farms is to stop milk production artificially commonly 2 months before expected calving, in a process termed drying-off. Dry-off management normally encompasses dietary changes as well as abrupt or gradual changes in daily milking frequency,...

Abstract

A possible driver of feed inefficiency in dairy cows is overconsumption. The objective was therefore to test precision feed restriction as a lever to improve feed efficiency of the least efficient lactating dairy cows. An initial cohort of 68 Holstein lactating cows was monitored from calving to...

Abstract

In this longitudinal study, we tested the hypothesis that cows that are lame around dry-off are at increased risk of transition diseases (TD), including metritis, subclinical ketosis (SCK), retained fetal membranes, hypocalcemia, or displaced abomasum. We also hypothesized that the relationship...
