A survey of total mixed ration use on pasture-based dairy farms in new york and pennsylvania. Pennsylvania Grazing and Hay & Silage Conference Proceedings. P. 13-18. Interpretive Summary: An interpretive summary is not required. Technical Abstract: Feeding a total mixed ration (TMR) on pasture-based dairies can reduce challenges associated with maintaining high levels of milk production under changing pasture quality and quantity. Many dairy producers in the Northeast and Midwest US have the knowledge and equipment for TMR feeding systems due to prior history as a confinement farm or because a TMR is fed in confinement during the non-grazing months. A survey was conducted to collect information on the use of a TMR on thirteen pasture-based dairy farms in New York and Pennsylvania, to monitor TMR ingredient and nutrient content and summarize what and how decisions are being made in relation to TMR formulation throughout the grazing season. The objective was to provide improved feeding recommendations to pasture-based dairies utilizing a TMR. In general, pasture replaced haylage/silage in the TMR diet, and protein level was often decreased in the TMR due to high pasture protein levels. Flexibility is key in utilizing a TMR on pasture-based operations to respond to changing pasture quality and quantity and to formulate least-cost rations. The basic principles of nutrition still apply- monitor dry matter intake, forage to concentrate ratios, and milk production. |
