To assess the impact of S fertilization on bahiagrass (Paspalum notatum) quality and Cu metabolism in cattle, two studies were conducted during the summer grazing season (1999 and 2000). Pasture replicates (16.2 ha; n = 2/treatment) received the same fertilizer treatment in each growing season, consisting of 1) 67 kg N/ha from ammonium sulfate (AS), 2) 67 kg N/ha from ammonium nitrate (AN), and...

This study evaluated the effects of calf management system following early-weaning (EW) on performance of beef steers. On d 0, Brahman x British steers (n = 40; bodyweight [BW] = 198 ± 26 lb; age = 72 ± 14 d) were stratified by age and BW, and randomly assigned to normal-weaning (NW; d 177) or 1 of 3 EW treatments: 1) EW and grazed on ryegrass pastures for 67 d then on bahiagrass pastures until...

Four experiments were conducted to evaluate the effects of dried distillers grains + condensed distillers solubles (DDG+CDS) supplements on measures of performance of beef heifers, and apparent dry matter (DM), neutral detergent fiber (NDF), and crude protein (CP) digestibility of beef steers. In Exp. 1, heifers supplemented with DDG+CDS blocks (SweetPro; SP) for 42 d had lesser free-choice sup...

Tropical soda apple (Solanum viarum Dunal) is a solanaceous weed, armed with prickles on stems, leaves, petioles, and calyxes. It is native to Argentina, Brazil, Paraguay, and Uruguay (26) and was introduced in the 1980s into Florida, where it thrives as a perennial, particularly in the southern part of the state (11). It has spread rapidly throughout Florida, now occurring on more than 405,000...
