Evaluación del bienestar animal en sistemas de producción de bovinos de leche intensivos de la zona central de Chile utilizando el protocolo Welfare Quality®
(UNIVERSIDAD DE CHILE, 2017)
El objetivo del presente estudio fue estimar el bienestar animal en rebaños lecheros de la zona
central de Chile utilizando el sistema de evaluación diseñado por Welfare Quality®. La
información fue recabada de acuerdo a las indicaciones del...
This study was to measured animal welfare parameters in the central region of Chile using the assessment protocol designed by Welfare Quality®. Data was collected according to the Welfare Quality® dairy farm protocol, between the years 2009 and 2010. To investigate if housing and herd size affect welfare, a total of 19 confined dairies with different housing system (9 free-stall and 10 open/dry lots) and herd size (small, medium and big) were selected. Results of this study show that global welfare is not significantly different between the two confinement systems and among herd sized assessed. However, this protocol allows to describe differences in welfare criteria, where “absence of prolonged hunger”, “expression of social behaviors” and “good human-animal relationship” showed a tendency to differ (p≤0,05) by housing system. “Expression of social behaviors” and “good human-animal relationship” were greater in the free-stall housing type; and “absence of prolonged hunger” was greater in the open/dry lot housing type. This study also evidenced poor behavior parameters in both housing systems, with values that the protocol Welfare Quality® qualifies as “acceptable” and “not classified”....

This review aimed to determine the importance of the quality of the human-pig relationship (HPR) and its assessment methods, by reviewing its effects on the animal welfare, cognition and productive performance of pigs reared in intensive systems. For its development, the PRISMA method was adapted, and a bibliographic search of several scientific articles published from 1981 to 2021 was carried out in different search engines. A total of 3,868 documents were reviewed, of which 3,792 texts were excluded because they did not meet the inclusion criteria. As a result, 96 scientific articles were used and subsequently analysed. In the field of animal welfare, the quality of HPR was linked to physical health or biological functioning, affecting several adaptive physiological mechanisms, such as neuroendocrine function, the immune system, the autonomic nervous system, and the gastrointestinal system. Concerning the behavioural state, the quality of HPR was related to the pig's demonstration of fear or affinity towards humans. The affective or mental state was linked to both behavioural and physiological responses associated with positive or negative emotional valence. In cognition, the quality of HPR was found to affect pigs' learning, memory, attention, and decision-making. Regarding the production performance, HPR quality was associated with effects on growth, reproductive performance, meat quality and safety. Thereafter, tests commonly used to assess the quality of RHC were reviewed, identifying various behavioural, physiological, and human affect indicators. These were analysed according to their applicability in the national intensive pig production system. Subsequently, a proposal for a protocol to evaluate the quality of the RHC was elaborated, considering the productive stage of the animal, its place of housing and the quality of human interactions. Taken together, this review demonstrates the considerable impact of the quality of RHA on the welfare, cognition and productivity of pigs reared in intensive systems while highlighting the practical implications of its assessment and its applicability at a national level....

Efectos de la carga de trabajo sobre indicadores sanguíneos de bienestar animal en mulas (Equus asinus x Equus caballus)
(Universidad de Chile, 2022)
Se realizó un estudio para evaluar el efecto de la carga en mulas y como la intensidad de trabajo puede afectar algunos parámetros sanguíneos que son indicadores de bienestar animal. Doce mulas adultas, pertenecientes del Ejército de Chile fueron...
A study was carried out to evaluate the effect of load on mules and how work intensity can affect some blood parameters that are indicators of animal welfare. Twelve adult mules, belonging to the Chilean Army were selected to carry out four 2-km trips carrying different amounts of loads on their backs. On each trip, 4 mules transported a light load (80 kg), 4 mules a moderate load (105 kg) and 4 mules a heavy load (130 kg), plus a control trip without load. In each test, HR, RR and rectal T° were measured, and samples were taken from the jugular vein to analyze the hematological and biochemical parameters. All these parameters were measured at 7 sampling times, before the trip (baseline), on arrival, at 10 minutes post-work, 2 hours post-work, one day post-work, three days post-work and five days post-work. The results showed significant increases (p<0.05) in short-term variables such as HR, RR, and plasma cortisol; for the remaining variables, expected alterations for a stress response were observed, that were normalized within the expected times. Muscle enzymes CK, LDH and AST showed slight increases associated with physical exercise, and it was not indicative of muscle damage. The GPx antioxidant enzyme maintained stable concentrations during all sampling times, confirming that the work did not generate oxidative stress. Serum Amyloid A (SAA) measured in the field, showed that the heaviest load, generated a mild inflammation in the mules, which after five days began to decrease. This study is one of the first approaches to working conditions in mules, based on reference intervals (RI) typical of this species, and it proved to be a low-intensity work that did not cause muscle damage and did not affect animal welfare...

Evaluación de riesgo de la pérdida del bienestar animal en el transporte de cerdos desde las unidades de producción hasta la planta faenadora
(Universidad de Chile, 2019)
El transporte es definido como uno de los procesos más estresantes que enfrentan los animales antes del momento del sacrificio; afectando la calidad de la carne, aumentando las mortalidades y por lo tanto comprometiendo su bienestar. Esta situación...
Animal transport is defined as one of the most stressful processes animals face before slaughter, affecting the quality of meat, increasing mortalities and therefore compromising their welfare. This represents important economic losses for producers and, to date, has become a differentiating attribute in developed countries where society mostly recognizes the concept of quality of a product beyond its safety and nutritional characteristics, showing a strong interest in the conditions in which animals are kept, transported and slaughtered, as evidenced in the regulatory framework of each country. In recent decades, it has been possible to develop conceptual models to estimate the impact of the conditions to which animals are exposed to and the welfare consequences derived from that exposure. Along these lines, the European Food Safety Authority (EFSA) has developed guidelines and a methodological framework to indirectly assess the risk of the welfare state in specific events of the production chain. The results of this thesis describe the conditions and infrastructure that the national industry declares to use during the transport. The absence of inspection of the pigs apt for the journey, the type of surface in the ramps and in the interior of the vehicle and the density of load are critical aspects to evaluate with respect to the current national regulations. In 5 out of 6 phases defined for transport, the greatest estimated risks were related to inappropriate handling of pigs, where the lack of personnel trained in aspects of animal welfare was identified as the most relevant factor....
