Abstract

The objective of the Research Internship Abroad (BEPE) is to continue the research conducted in Brazil. Given the complexity and diversity of the results generated, the opportunity to share them with another researcher in the field is essential to promote better interpretation and enrich the research. This is particularly relevant for renal health analyses, an area that has been minimally explored by our research group. However, Professor Carmen Mª Pineda Martos already has relevant publications in the areas of renal health and mineral metabolism, which will provide valuable contributions to the interpretation of the results.The research conducted in Brazil focused on evaluating and comparing phosphoric acid and ammonium chloride as urinary acidifying agents for cats and their effects on renal phosphorus excretion, phosphorus metabolism, renal health parameters, water balance, and relative urinary supersaturation (RSS) for calcium oxalate and struvite. Additionally, the addition of phosphorus from an inorganic source (phosphoric acid) will be compared with an organic source (bone) in terms of its apparent absorption, renal excretion, phosphorus metabolism, renal health parameters, and RSS for struvite and calcium oxalate.During the period abroad, data will be analyzed, including ultrasound images of the kidneys, to determine how and to what extent the consumption of the experimental diets has modified, during this period, the renal health parameters of the cats. This central aspect of the research will greatly benefit from the participation of Professor Pineda Martos.
