Bienestar animal y su relación con la calidad de carne en bovinos faenados en el Centro de beneficio de Paute

Abstract

The aim of this study is to assess the animal welfare of bovine animals prior to slaughter and the influence on the quality of bovine meat by studying qualitative and quantitative animal welfare parameters. The study will be carried out at the Paute Benefit Center, where 385 cattle will be selected at random from different localities. To evaluate the welfare of the animal, 10 parameters combined between the method of Welfare Quality and that of the American Meat Institute created by Grandin (2001) will be considered. The dimensions to be measured will be: Transport time, flow of animals in the farm, type of drinking water, access to water, falls and slips, use of electric picanas, state of health, number of shots used to numb them, degree of insensitivity and time for bleeding. After observing these parameters, the pH and temperature in the semimembranosus muscle will be measured at 45 min and 24 hours post mortem. An univariate analysis and absolute and relative frequency tables will be used to evaluate the variables corresponding to meat quality parameters: PH, temperature and cortisol will be measured with laboratory tests and blood collection prior to fainamiento and post mortem. Something very common that significantly affects the emotional state of the animal to fish is transport since the stress that causes them to come overcrowded, mistreated or in its defect being of transfer for more than 24 hours also considerably affects the increase of cortisol in the blood. Testing of normality and flexibility will be performed. To establish the relationship between the qualitative variables corresponding to animal welfare with respect to pH, a multiple factorial analysis (ANOVA) and Kruskal Wallis tables will be used. The data collected will be analyzed in the SPSS statistical program version 24.
