Supplementing Pasture to Lactating Holsteins Fed a Total Mixed Ration Diet

Performance of lactating dairy cows fed varying levels of total mixed ration and pasture.

Two, 8-week experiments, each using 30 lactating Holstein cows, were conducted to examine performance of animals offered combinations of total mixed ration (TMR) and high-quality pasture. Experiment 1 was initiated in mid October 2004 and Experiment 2 was initiated in late March 2005. Cows were assigned to either a 100% TMR diet (100:00, no access to pasture) or one of the following three formu...

Intake of High Producing Holstein Cows Grazing Pasture or Fed a Total Mixed Ration

(week 4). Intake was estimated in week 4 by dosing twice daily with 5 g Cr 2 O 3 for 10 days. Fecal samples were collected twice daily on days 7 to 11 of Cr 2 O 3 dosing, with pre-grazing pasture being sampled on days 6-10 of dosing. Fecal output, calculated from fecal chromium concentrations, and in vitro digestibility (IVDMD) were used to calculate intake (Parker et al. 1989). The intake of c...

Metabolic Adaptations Due to the Inclusion of Pasture in the Diet of Dairy Cows Fed Total Mixed Ration during Early Lactation

The aim of this study was to evaluate the metabolic adaptations due to the inclusion of pasture in the diet of dairy cows fed on a total mixed ration (TMR) ad libitum during early lactation. Multiparous cows (n = 18) were used in a randomized complete block design and were randomly assigned according to parity, BW and BCS to one of two feeding strategies from calving to 60 DIM: 1) cows fed TMR ...

Adding liquid feed to a total mixed ration reduces feed sorting behavior and improves productivity of lactating dairy cows.

This study was designed to determine the effect of adding a molasses-based liquid feed (LF) supplement to a total mixed ration (TMR) on the feed sorting behavior and production of dairy cows. Twelve lactating Holstein cows (88.2±19.5 DIM) were exposed, in a crossover design with 21-d periods, to each of 2 treatment diets: 1) control TMR and 2) control TMR with 4.1% dietary dry matter LF added. ...
