Environmental temperature and its effect on physiological parameters in Nellore cows and crosses under conditions of the Peruvian tropics

Descripción del Articulo

The aim of this study was to determine the physiological parameters related to body thermoregulation, as well as basic haematological parameters between Nellore cows and crossbreeds under heat stress. The study was carried out in the province of Satipo, Junín region, Peru, at 628 meters above sea le...

The study was carried out in the province of Satipo, Junín region, Peru, at 628 meters above sea level. Sixteen crossbred cows (Brown Swiss x Nellore) and 16 Nellore cows were used. The physiological parameters (body temperature, respiratory rate and heart rate) were evaluated in the morning (06:00-07:00) and in the afternoon (14:00-17:00). Blood samples were taken to determine haemoglobin (g/dl), haematocrit (%), mean corpuscular volume (MCV, fl), mean corpuscular haemoglobin (MCH, pg), mean corpuscular haemoglobin concentration (MCHC, g/dl). Thermoregulatory functions (rectal temperature, heart rate and respiratory rate) were affected during hours of heat stress in both racial groups (p<0.05). Haematological values were found within the referential ranges, except the MCV and MCH.El objetivo del estudio fue determinar las constantes fisiológicas relacionadas con la termorregulación corporal, así como parámetros hematológicos básicos entre vacas Nellore y sus cruces bajo estrés calórico. El estudio se desarrolló en la provincia de Satipo, región Junín, Perú, a 628 msnm. Se trabajó con 16 vacas cruzadas (Brown Swiss x Nellore) y 16 vacas Nellore. Las constantes fisiológicas (temperatura corporal, frecuencia respiratoria y frecuencia cardiaca) se evaluaron en horas de la mañana (06:00-07:00) y en la tarde (14:00-17:00). Se tomaron muestras de sangre para determinar hemoglobina (g/dl), hematocrito (%), volumen corpuscular medio (VCM, fl), hemoglobina corpuscular media (HCM, pg), concentración de hemoglobina corpuscular media (CHCM, g/dl). Las funciones termorreguladoras (temperatura rectal, frecuencia cardiaca y frecuencia respiratoria) se vieron afectadas en horas de estrés calórico en los dos grupos raciales (p<0.05). Los valores hematológicos se encontraron dentro de los rangos referenciales, excepto el VCM y la HCM.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Veterinaria2020-03-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/1754910.15381/rivep.v31i1.17549Revista de Investigaciones Veterinarias del Perú; Vol. 31 Núm. 1 (2020); e17549Revista de Investigaciones Veterinarias del Perú; Vol. 31 No. 1 (2020); e175491682-34191609-9117reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/veterinaria/article/view/17549/14825Derechos de autor 2020 Ide Unchupaico P., Luis Bazán A., Carlos Quispe E., Edith Ancco G.https://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/175492020-03-30T00:45:29Z
