Abstract
This study evaluated animal production of steers and pasture production of natural grassland and grassland overseeded with Italian ryegrass (Lolium multiflorum), white clover (Trifolium repens) and birdsfoot trefoil (Lotus corniculatus), with and without the use of glyphosate herbicide. Treatments consisted of: NG – natural grassland, with annual mowing; ING – natural grassland with overseeding, fertilizing and annual mowing; G1 – Same ING, but with glyphosate application in the first year; G3 – same as G1, with suppression of natural vegetation using herbicide in the second and third years; GF3 – same as G3, with doubled fertilizing in the three years. The experimental design consisted of completely randomized blocks with two replications. The results presented are from the third year of evaluation. For average daily weight gain, there were differences (p &le 0.1) among treatments and periods, varying from 0.214 kg animal-1 day-1 in NG to 1.406 for the treatments with introduction of species. Live weight gain per area varied from 84 to 410 kg of LW ha-1. The stocking rates varied from 283 to 679 kg of LW ha-1. The herbicide did not present effects on production; and introduction of cool season species by overseeding improved animal production in NG, resulting in higher animal performance per animal and per area.Downloads
