Enhancing the adoption of stockpiling tall fescue and managed grazing

One of the primary goals of extension is to encourage and support adoption of improved technologies. Managed grazing and stockpiling forage are two such technologies. The goal of this project was to encourage adoption of these practices by providing on-farm demonstrations of the technologies. We also collected forage and soil data and held workshops at each of the demonstration sites. Host producers were selected, given a basic kit of temporary fencing supplies for use during the demonstration, and instructed on their proper use during the winter stockpiling season. Forage yield and quality data were collected and soil tests made to show the economic advantages of proper fertilization and grazing fresh forage in contrast to feeding stored forage and concentrate. The nutritive value of the forage stockpiled in September through November (67% total digestible nutrients [TDN] and 14% crude protein, CP) exceeded the needs of the cattle and was greater than the nutrient content of hay present on the farms (59% TDN and 11% CP, P < 0.01). The mean quantity of available forage (2,856 ± 164 kg dry matter per hectare) provided an average of 260 (±81.8) standard cow (545 kg) grazing days per hectare of stockpiled forage. Taking into account the higher nutritive value of the fresh forage when compared with hay and the savings of time and equipment costs by grazing, we estimated that grazing stockpiled forage saved $1.28 per standard cow per day. The grazing management skills gained during this project and the temporary fencing technology were adopted by 93% of the demonstration farms that responded to our follow-up survey (78% of demonstration sites), and the area managed with these technologies increased on these sites more than 350%. Having the hosts share personal experiences played an important role in encouraging their peers to adopt the technologies.
