Preweaning growth data were obtained during 4 yr on 349 Braford-sired calves from Brahman-Hereford F1 first-calf females. These females were allotted to either semiarid rangeland (Uvalde) or humid improved pasture (Overton) as weanlings and to one of four herbage allowance levels at each location as yearlings. Females were wintered on systems in local industry practice and maintained on various...

Abstract Maintenance of pastures for grazing accounts $132.50/animal in the United States (23% operating costs), and pasture nutrient input represents single greatest influence productivity per unit area. Cultivar differences forage offered to cattle have potential manifest digestive efficiency, resulting different excretion profiles. The objective this study was assess growth incorporation N, ...

in order to investigate the effect of urea and azocompost on economic yield, nitrogen use efficiency (nue) and radiation use efficiency (rue) of wild majoram, a factorial experiment was conducted based on randomized complete block design with three replications at yazd and mashhad, iran, during 2012-2013 growing season. four urea levels and four azocompost levels (to provide 0, 40, 80 and 120 k...

Yellow sweet clover is a widely spread legume species that has potential to be used as a forage crop in Western China. However, limited information is available on the genetic variation for herbage yield, key morphological traits, and coumarin content. In this study, 40 half sib (HS) families of M. officinalis were evaluated for genotypic variation and phenotypic and genotypic correlation for t...

Mimosa pudica is the most abundant and problematic invasive species in tropical pastures. This study investigates the effects of two cattle grazing systems, long-term moderate grazing (LTG, 2.7 animal unit/ha/yr for 33 years) and short-term heavy grazing (STG, 5 animal unit/ha/yr for 2 years) compared with ungrazed exclosure pasture on the invasion of M. pudica and its relationship with herbage...

Cowpea is an important grain legume crop used as feed for livestock, and its dry beans provide protein. Consequently, the objective of this study was to evaluate selected cowpea genotypes herbage matter yield nutritional quality in two agro-ecologies Benishangul-Gumuz region. The conducted at Kamashi Assosa forages research stations Agricultural Research Center, sites were purposively represent...
