Hemato-biochemical profile of meat cattle submitted to different types of pre-loading handling and transport times

Abstract

Pre-loading handling and conditions of transport are related to welfare, disease risk and product quality of production animals. These steps continue to be one of the major animal management problems in Brazil. This study evaluated the effects of different types of pre-loading handling and road transport times on the haematological and biochemical traits of cattle. Eighteen male cattle were submitted to three travel times (24, 48 and 72 h) in a truck soon after load using different types of pre-loading handling: traditional (rough handling), training (gentle handling) and use of flags to movement cattle. Haematological traits, blood biochemical measures as well as blood and faecal cortisol were analysed in order to assess animal welfare and physiological status. The traditional management showed to be more stressful, also had animals with a greater number of neutrophils and lower numbers of lymphocytes than handling with flags, showing that animals submitted to more stressful situations can have compromised immune system. Serum aspartate aminotransferase concentrations were within the reference levels and when taken together with increased creatine kinase patterns observed indicate muscle damage in traditional management. Decrease in glucose concentrations over time from traditional management to flag management was observed, while fructosamine was increased in traditional management with 72 h of travel. When taken together, all reported factors, immune, enzymatic, energetic and hormonal, indicate that the quality of pre-loading handling and time of transport were determinant for animal welfare, its homeostatic balance and sanitary conditions.

Hematological Profile of Aceh Cattle

“…Studies conducted on Aceh cattle, including physiological baseline studies, are relatively fewer compared to other Indonesian local cattle breed. The knowledge of physiological status is essential as a reference for the implementation of various The hematological profile is one of the physiological variables that can be used to determine health status, production, and animal welfare of livestock (Siswanto, 2011;Otter, 2013;Roland et al, 2014;Bezerra et al, 2017;Brunel et al, 2018). A proper blood profile can support the physiological processes of the livestock so they can provide optimal performance (Ali et al, 2013).…”

Alteraciones del pH y temperatura en la canal a causa de factores relacionados al transporte bovino previo al sacrificio

“…La carne de estos animales se caracteriza por ser firme, sin exudar agua y refleja menos luz, con el consiguiente oscurecimiento. Dichas carnes tienen una elevada capacidad de retención agua (CRA) y un mejor rendimiento industrial, aunque debido a su pH menos ácido este alimento es más propenso de sufrir alteraciones por microorganismos (Brunel et al, 2018;Gonzalez-Rivas et al, 2020). Para la identificación de carnes DFD se debe tomar dos medidas de pH, una inicial al momento posterior al sacrificio (pH0) y otras 24 horas después del faenamiento (pHu o pH final), debido a que la curva de descenso del pH en relación a una carne normal en pH0 es muy similar y solo se nota la diferencia 24 horas después.…”

Hematological Profile and Leukocyte Differentiation of Madura Cattle and their Crosses at Different Sexes and Ages

“…Knowledge of physiological status is essential as a reference for implementing of various maintenance systems in livestock. The Haematological profile is one of the physiological variables that can be used to determine livestock's health status, production, and welfare (Bezerra et al, 2017;Brunel et al, 2018). The proper blood profile can support the physiological processes of livestock to provide optimal performance (Ali et al, 2013).…”
