(Wiley, 2023-03)Spike fertility index (a.k.a. fruiting efficiency) at maturity (FEm -grain number per spike/g spike chaff at maturity-) and spike harvest index (SHI -grain weight per spike/g spike chaff weight at maturity-) are considered ... -
Consumer Attitudes and Concerns about Beef Consumption in Argentina and Other South American Countries
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-03)In South America, modifications in beef consumption habits, mainly related to economic reasons, new lifestyles, and new eating behaviors, are being observed. If this trend continues, beef consumption could continue to fall ... -
Molecular insights into quality and authentication of sheep meat from proteomics and metabolomics
(Elsevier, 2023-03)Sheep meat (encompassing lamb, hogget and mutton) is an important source of animal protein in many countries, with a unique flavour and sensory profile compared to other red meats. Flavour, colour and texture are the key ... -
Does nitrogen fertilization rate, timing and splitting affect sunflower yield and grain quality?
(Wiley, 2023-02)Nitrogen (N) deficiency could have a negative effect on sunflower (Helianthus annuus L.) yield and grain quality. Therefore, it is necessary to adjust the optimum rate, timing, and frequency of N fertilization to improve ... -
Microscopic lesions and modulation of gene expression in cervical medulla during BoAHV-1and BoAHV-5 infection: A mini-review
(Elsevier, 2023-03)Bovine herpesvirus (BoAHV) types 1 and 5 are closely-related neurotropic alpha-herpesviruses. BoAHV-1 generally causes respiratory and genital disease but can occasionally cause encephalitis. BoAHV-5 is the causative agent ... -
Effectiveness of hermetic bag storage technology to preserve physical quality attributes of shea nuts
(Elsevier, 2023-03)Shea nuts are a nutritionally and economically important tree crop harvested seasonally in rural areas of sub-Saharan Africa. Storage losses are a major constraint in the shea nut value chain, with substantial amounts lost ... -
Equine abortion and stillbirth in California: a review of 1,774 cases received at a diagnostic laboratory, 1990–2022
(SAGE Publications, 2023-02)Reproductive failure represents an important cause of economic loss for the equine industry. We reviewed the cases of equine abortion and stillbirth submitted to the California Animal Health and Food Safety Laboratory ... -
Modelling pasture management practices for soil organic carbon gain in livestock systems
(Wiley, 2022-09-13)Our ability to develop strategies to mitigate climate change includes an understanding of, and our capacity to predict soil organic carbon (SOC) dynamics in livestock systems. Here we assess the capability of the Sustainable ... -
