Alternative animal feeds from agroforestry plants
(Springer, 2020-07)This special issue idea originated when a few researchers from around the world came together with the goal of compiling the most up-to-date information on the use of alternative animal feed resources derived from agroforestry ... -
Comparison of 4 methods for determining in vitro ruminal digestibility of annual ryegrass
(Elsevier Science, 2018-12-01)Existen múltiples métodos de IVDMD, pero la información que compare los resultados obtenidos por diferentes métodos es escasa. Este estudio tuvo como objetivo comparar 3 métodos IVDMD diferentes [DaisyII (DY), cultivo por ... -
Compuestos secundarios de especies vegetales nativas como agentes para mejorar la tolerancia a aguas de bebida con elevados tenores de sulfatos en rumiantes
(Facultad de Agronomía, Universidad de Buenos Aires, 2022-08)El objetivo de este trabajo fue evaluar el impacto de los taninos condensados (TC) de especies nativas con potencial inhibidor de la reducción ruminal de sulfatos (SO4) como alternativa para mejorar la tolerancia de los ... -
Degradable intake protein supplementation through the inclusion of urea in finishing diets containing distillers grains: effects on feedlot cattle performance, ruminal fermentation, and feed digestibility
(University of Minnesota, 2014-05)Degradable intake protein (DIP) represents the proportion of protein that is potentially fermented in the rumen. Ruminal DIP balance is calculated by the difference between DIP supply and requirements. The former is a ... -
Dietary nitrate and presence of protozoa increase nitrate and nitrite reduction in the rumen of sheep
(Wiley, 2020-04)Nitrate (NO−3) supplementation is an effective methane (CH4) mitigation strategy for ruminants but may produce nitrite (NO−2) toxicity. It has been reported that rumen protozoa have greater ability for NO−3 and NO−2 reduction ... -
Dynamics of the ruminal microbial ecosystem, and inhibition of methanogenesis and propiogenesis in response to nitrate feeding to Holstein calves
(Elsevier, 2021-12)It is known that nitrate inhibits ruminal methanogenesis, mainly through competition with hydrogenotrophic methanogens for available hydrogen (H2) and also through toxic effects on the methanogens. However, there is limited ... -
Efecto del nivel de suplementación con granos de destilería sobre la utilización y producción de metano de Panicum maximum (cv. gatton) diferido en bovinos para carne
(Facultad de Agronomía y Zootecnia, Universidad Nacional de Tucumán, 2017-12-14)La suplementación energético-proteica de forrajes de baja calidad es una práctica necesaria para lograr un adecuado desempeño animal durante la estación seca en sistemas ganaderos a base de pasturas megatérmicas. En la ... -
Efectos del consumo de distintos niveles de semilla de algodón sobre las variables ruminales de novillos cruza cebú
(2015-06)La semilla de algodón (SA) constituye un recurso alimenticio importante para el ganado del nordeste argentino por su bajo costo y alto nivel nutritivo. El objetivo de este trabajo fue verificar los cambios provocados a ... -
Effect of concentrate supplementation on ruminal papillae growth and rumen wall development in calves
(Ediciones INTA, 2023-12)The growth of ruminal papillae and rumen thickness in calves subjected to two different feed rations were evaluated. Two homogeneous treatment groups were established, consisting of four individuals each (T1 and T2). T1 ... -
Effect of slow-release urea inclusion in diets containing modified corn distillers grains on total tract digestibility and ruminal fermentation in feedlot cattle
(American Society of Animal Science, 2015-08)Ruminal degradable intake protein (DIP) deficit may result when cattle are fed diets containing a greater inclusion of processed corn grain and small to moderate inclusion of corn distillers grains (DG). This deficit may ... -
Effects of supplementation with increasing levels of energy concentrate on the productive response and ruminal digestion of dairy cows grazing lucerne pasture
(Scientific Research, 2018-11)The aim of the study was to determine the effect of three levels of energy concentrate intake on dry matter (DM) and energy intake, milk yield and composition, rumen environment and pasture neutral detergent fiber (NDF) ... -
Engorde de bovinos a corral : efectos de monensina y de dos niveles de taninos condensados de quebracho sobre el comportamiento productivo, la fermentación ruminal y la degradabilidad in situ de la materia seca y de la proteína = Feedlot cattle: effects of monensin and two levels of quebracho tannin extract on performance, ruminal fermentation and in situ dry matter and protein degradability
(Asociación Argentina de Producción Animal, 2013)Se llevaron a cabo dos ensayos a fin de evaluar el efecto de dos niveles de taninos condensados de quebracho colorado (Schinopsis quebracho-colorado) en comparación con monensina sobre el comportamiento productivo, la ... -
Essential oils from Argentinean native species reduce in vitro methane production
(2018-04)The aim of this study was to evaluate the effect of Argentinean essential oils (EO) on methane production during in vitro fermentation compared to EO with proven effects as rumen fermentation modifiers. A complete randomized ... -
Impactación ruminal y abomasal en vacas de cría asociada al consumo de una pastura diferida de Megathyrsus maximus cv. Gatton
(Facultad de Ciencias Veterinarias de Esperanza, Universidad Nacional del Litoral, 2019)La impactación ruminal y abomasal es una afección de los rumiantes que se produce cuando estos consumen un alimento de muy baja digestibilidad y bajo contenido proteico y energético. En este trabajo, se describe una mortandad ... -
Isolation of Pseudobutyrivibrio ruminis and Pseudobutyrivibrio xylanivorans from rumen of Creole goats fed native forage diet
(Springer, 2013-09)We isolated and identified functional groups of bacteria in the rumen of Creole goats involved in ruminal fermentation of native forage shrubs. The functional bacterial groups were evaluated by comparing the total viable, ... -
Nitrate and nitrite absorption, recycling and retention in tissues of sheep
(Elsevier, 2021-07)Dietary nitrate is of increasing interest both for the pharmacological effects of its metabolites as well as its capacity to inhibit methanogenesis in the gut. A sequence of three experiments was conducted to investigate ...
