Animal performance, carcass characteristics and beef quality of steers fed with a whole oat or maize grain-based diet
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2023-11)Aim of study: We evaluated the use of oat grain as an alternative source of energy to maize grain in high energy finishing diets. Maize crop production in arid and semi-arid areas is poor or non-existent. Thus, small grains ... -
Antioxidant status, lipid and color stability of aged beef from grazing steers supplemented with corn grain and increasing levels of flaxseed
(2016-01)Angus steers were grazed on unsupplemented pasture (CNTRL), pasture supplemented with 0.7% BW cracked corn (FLAX-0), FLAX-0 with 0.125% and 0.250% BW of whole flaxseed (FLAX-1 and FLAX-2). Six steers were grazed per treatment ... -
Biochemical profiles and physicochemical parameters of beef from cattle raised under contrasting feeding systems and pre-slaughter management
(CSIRO, 2015-01)Diet and pre-slaughter stress are key factors that may affect the biochemical processes during conversion of muscle into meat. The aim of the present study was to evaluate the effect of two different pre-slaughter stress ... -
Calidad nutricional de carne de novillos suplementados con granos de destilería en dietas de terminación
(Asociación Argentina de Producción Animal, 2021-11)Distillery grains (GD) are a by-product of the industry of bioethanol from corn, used as ingredient in bovine diets. The DGs provide the nutrients from corn, with the exception of sugars, and has been observed leading ... -
Combined use of monensin and virginiamycin to improve rumen and liver health and performance of feedlot-finished steers
(American Society of Animal Science, 2022-12)Monensin and virginiamycin are included in beef cattle finishing diets as prophylaxis to minimize the incidence of ruminal acidosis and liver abscesses. Due to different and probably complementary modes of action, this ... -
Comparación de dos alternativas de invernada intensiva con biotipos británicos
(EEA Marcos Juárez, INTA, 2017-10-01)En un marco de intensificación de la ganadería en la región pampeana, el uso de encierres a corral combinados con etapas pastoriles surge como una alternativa promisoria para lograr sistemas intensivos eficientes. El ... -
Diet and genotype effects on the quality index of beef produced in the Argentine Pampeana region
(Elsevier, 2008-07)Steers of varying genotypes (Aberdeen Angus, Charolais x AA and Argentine Holstein) in four feeding systems were evaluated. Feeding systems were: S1 = a diet based on pastures only; S2 = a similar forage base as S1 plus a ... -
Dried distiller´s grains plus solubles supplementation improves low-quality tropical grass utilization on beef steers = Suplementação de grãos de destilação secos com solúveis melhora a utilização de grama tropical de baixa qualidade para novilhos de corte
(Centro de Ciências Rurais, Universidade Federal de Santa Maria, 2022)This study was designed to evaluate the effect of corn dried distiller´s grains (DDGS) supplementation on feed intake, total tract digestibility, and ruminal fermentation of beef steers fed low-quality Guinea grass ... -
Efecto de la dieta sobre la composición en ácidos grasos y los índices de interés nutricional en la grasa subcutánea de novillos de diferentes genotipos.
(Foro de la Alimentación, la Nutrición y la Salud, 2020)El objetivo del presente trabajo fue analizar la composición de la grasa subcutánea de novillos Hereford, Bradford ½, Bradford ¼ y Bradford 3/8, alimentados con tres dietas diferentes: Pasturas, Pasturas + 0.7% de ... -
Efecto de la maduración sobre la calidad de la carne en novillos brangus
(Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2008-09)Se utilizaron 193 terneros de destete de raza Brangus, provistos por seis cabañas pertenecientes a la Asociación Argentina de Brangus, engordados sobre pasturas permanentes en el oeste de la provincia de Buenos Aires y ... -
Enteric listeriosis in grazing steers supplemented with spoiled silage
(2016)An outbreak of enteric listeriosis in steers that were fed spoiled silage is reported. The outbreak started 2 days after ~200 animals in a single paddock were given a supplement of spoiled silage. Forty animals (20%) were ... -
Estimating overnight weight loss of corralled yearling steers in semiarid rangeland
(2016)A common practice for assessing livestock weight gains from grazing animals on rangelands is to confine animals overnight without feed or water to reduce variation in weight loss and percent shrink. Advances in remote ... -
Extending the feeding period beyond 8.0 mm of subcutaneous fat reduces feed efficiency without improving meat colour and tenderness of non-implanted feedlot steers
(Polish Academy of Sciences, 2022-06-20)The effect of extending the pen-feeding period of non-implanted feedlot steers beyond the 8.0 mm fat thickness (FT) endpoint on performance, carcass and meat traits was evaluated. Sixty-four medium-sized British steers ... -
