Adequate vegetative cover decreases nitrous oxide emissions from cattle urine deposited in grazed pastures under rainy season conditions
(Nature Publishing, 2019-01-29)A decline in pasture productivity is often associated with a reduction in vegetative cover. We hypothesize that nitrogen (N) in urine deposited by grazing cattle on degraded pastures, with low vegetative cover, is highly ... -
Exogenous progesterone during in vitro fertilization improves developmental competence of partially cumulus-denuded bovine oocytes
(Elsevier, 2023-11)The progesterone (P4) secreted by cumulus cells has gained attention for its role as a possible physiological inducer of sperm acrosome exocytosis. In mammals, it is generally accepted that fertilization rates of oocytes ... -
Feedbase intervention in a cow-calf system in the flooding pampas of Argentina: 2. Estimation of the marginal value of additional feed
(Elsevier, 2017-11)Temporal variability in the availability of forage reduces the production and economic performance of livestock systems. The marginal value of feed (MVF, the possible gross economic benefit of additional feed on offer ... -
Methane and nitrous oxide emissions from dung patches deposited by grazing cattle supplemented with maize grain
(Elsevier, 2021-07-13)Feeding management represents an opportunity to improve cattle performance in grazing-based production systems and to mitigate emissions of greenhouse gases (GHG) from livestock production. However, it is unclear how diet ... -
Parasitemia and Associated Immune Response in Pregnant and Non-Pregnant Beef Cows
(Frontiers Media, 2022-06)The aim of this longitudinal study was to characterize the parasitemia of Neospora caninum and the associated immunological parameters in naturally infected beef cows for 10 months. The following groups were established: ...
