The increasing cost of feed supplements necessitates evaluation of alternatives for ruminant livestock grazing poor quality warm-season grasses. This study determined how supplementing bahiagrass hay (Paspalum notatum Flügge cv. Pensacola) with soybean [Glycine max (L.) Merr.] meal or warm-season legume hays affected intake, digestibility, and N utilization by lambs. Dorper x Katadhin crossbred...

Nutrient cycling via livestock excreta is an important grassland ecosystem service. This study was conducted in 2016 and 2017 determined nutrient excretion from cattle grazing three systems: (a) N-fertilized bahiagrass (Paspalum notatum Flüggé) overseeded with rye (Secale cereale L.) oat (Avena sativa during winter (Grass+N), (b) unfertilized rye–oat–clover (Trifolium sp.) mixture (Grass+clover...

Abstract Bahiagrass ( Paspalum notatum Flüggé) is a rhizomatous, perennial, warm‐season forage widely grown in the southeastern United States "UF Riata" bahiagrass more upright growing with greater herbage production when days are shorter compared most other cultivars. Lesser daylength sensitivity extends grazing season, but combination growth may negatively affect persistence under grazing, es...

Brahman × British crossbred steers (n = 40 and 38 in yr 1 and 2, respectively) were used to evaluate the effects of calf management systems following early weaning (EW) on growth performance, muscle gene expression, and carcass characteristics. On the day of EW (d 0), steers were stratified by BW and age (95 ± 14 kg; 74 ± 14 d) and randomly assigned to a control treatment that was normally wean...

BACKGROUND, AIM, AND SCOPE Recent assessments of water quality status have identified eutrophication as one of the major causes of water quality 'impairment' not only in the USA but also around the world. In most cases, eutrophication has accelerated by increased inputs of phosphorus due to intensification of crop and animal production systems since the early 1990 s. Despite substantial measure...

An experiment was conducted to evaluate the effects of feeding co-products with Optigen ® II on animal performance and blood metabolites in growing beef calves. Angus steers were allowed ad libitum access to bahiagrass hay and were supplemented for 42 d via Calan gates. Treatments included 1) dried distillers grains; 2) dried distillers grains + Optigen; 3) soybean hulls; 4) soybean hulls + Opt...

Brahman × British crossbred heifers (n = 40 and 38 heifers in yr 1 and 2, respectively) were used to evaluate the effects of calf weaning age and subsequent management system on growth and reproductive performance. On d 0, heifers were ranked by BW (89 ± 16 kg) and age (72 ± 13 d) and randomly assigned to a conventional management group that was normally weaned on d 180 (NW; n = 10 heifers annu...
