A study was conducted on the use of a partial total mixed ration (pTMR) on 13 pasture-based dairy farms in New York and Pennsylvania. The objectives of the study were to monitor and summarize management decisions made in relation to pTMR formulation

Forty-five Holsteins cows in early to mid-lactation were used to evaluate the milk fatty acid composition of three feeding systems that combined pasture and total mixed ration (TMR) in a 19-week experiment. The three treatments were: (1) pasture plus

The results of 14 research studies indicated that grazing dairy cows fed monensin respond similarly in milk yield and milk composition to dairy cows fed in confinement. When compared to controls, grazing cows receiving monensin averaged 0.9 kg/cow pe

Partial budgeting was used to compare income over feed costs of high-yielding Holstein cows based on data from an experiment with 4 dietary treatments arranged in a 2 × 2 factorial. The factors were low (25 kg DM/cow per day) and high (40 kg DM/cow

Twenty multiparous Holstein cows were used in a completely randomized design with repeated measures to study milk production of cows supplemented or not supplemented with concentrate when they were switched to a total mixed ration (TMR) after grazing
Effects of fat supplementation on milk production and composition by dairy cows on pasture: a review

Eighteen experiments involving 25 comparisons were reviewed to describe the main effects of fat supplementation on milk production and composition with grazing dairy cows. Results were analyzed comparing the fat supplemented and the control groups wi

Thirty-one Holstein cows (six ruminally cannulated) were used to evaluate milk fatty acids (FA) composition and conjugated linoleic acid (CLA) content on three dietary treatments: 1) total mixed rations (TMR), 2) pasture (Avena sativa L.) plus 6.7 kg

A continuous culture system was used to investigate ruminal digestion in response to increased pasture intake and three different substitution rates (SR) in a 4×4 Latin square design. The treatments were 1) low pasture (55g dry matter (DM)/d, 2) med
