Abstract/Contents:"A test was conducted at the Livestock and Forestry Research Station, Batesville, Arkansas to evaluate the effect of mefluidide on tall fescue quality. The test area was a 20-acre block of well established 'Kentucky 31' tall fescue with 56 percent level of endophyte infestation. The 20 acres were fertilized with 80 pounds of nitrogen per acre as urea on February 15, 1985. Water, minerals and shade were available at all times. Mefluidide was applied April 1, and the cattle were moved onto the test site on April 16. The test animals were 20 heifers from the same herd ranging from 505 to 625 pounds. Five animals were placed on each five-acre block. The animals were weighed every 28 days from April 16 to July 16. The test was terminated due to lack of forage on August 8, 21 days after the July 16 weighing. Average daily gain for the animals on the treated fescue was 0.18 pounds greater for the first 28 days and 0.28 pounds for the second 28 day period. Average daily gain for the next 49 days was essentially the same for animals grazing treated and untreated fields. The ten heifers grazing the mefluidide-treated pastures gained a total of 1,065 pounds between April 16 and August 6, while the animals on the untreated fescue gained 1,070 pounds during the same peiod. One factor contributing to the lack of difference may have been the declining fescue stand on one of the mefluidide-treated fields. This deficiency was not obvious in March and April but became apparent with the beginning of hot, dry weather. There was no visible improvement in the appearance of the animals on the treated versus untreated fields. Both groups of animals had rough coats throughout the season. During July and August, both groups were standing in the ponds by 8 to 9 a.m. Forage samples were collected at each of the weighing dates and analyzed for quality. The quality of the mefluidide-treated fescue was superior at the first sample date, but little difference was noted in the samples collected later. Mefluidide gave 100 percent seedhead inhibition and caused stunting and discoloration of the fescue for the first two to three weeks after treatment. This may have had some influence on the initial performance of the animals on the mefluidide-treated fescue. The animals on untreated fescue were able to use all of the available grass, so a hay cutting was taken on May 15. Twenty-seven and one-half large round bales (approximately 1000 pounds each), were harvested from the untreated fields. On June 29, six and one-half bales were harvested from the treated fields."
