Efecto del tiempo de espera en el matadero sobre el bienestar de corderos lechales

In this paper, the effect of lairage before slaughter on the welfare and carcass and meat quality in suckling lambs has been studied. Four lairage times have been evaluated, L0 no-lairage, L3 lairage of 3 h, L6 lairage of 6 h and L12 lairage of 12 h. Blood parameters, cortisol, creatine kinase (CK), lactate dehydrogenase (LDH), total protein and amyloid A protein, weight loss during lairage, carcass quality and meat pH in two longissimus and semitendinosus muscles have been studied. Lambs with a lairage of 12 hours showed higher level of cortisol, total protein and amyloid A protein, besides a greater live weight loss, indicating that had a higher stress response and further dehydration. The meat pH was higher in both muscles in the group L3. The lairage increased animal welfare concerns but not the quality of the meat.En este trabajo se estudia el efecto que el tiempo de espera antes del sacrificio tiene sobre el bienestar y la calidad de la canal y la carne en corderos lechales. Se han estudiado cuatro tiempos de espera, L0 sin periodo de espera, L3 espera de 3 h, L6 espera de 6 h y L12 espera de 12 h. Se han valorado parámetros sanguíneos, cortisol, creatin kinasa (CK), lactato deshidrogenasa (LDH), proteínas totales y proteína amiloide A, así como pérdidas de peso por la espera, calidad de la canal y la evolución del pH de la carne en dos músculos longissimus y semitendinosus. Los corderos que estuvieron esperando 12 h mostraron un mayor nivel de cortisol, proteínas totales y proteína amiloide A, además de tener una mayor pérdida de peso, lo que indica que tuvieron una mayor respuesta de estrés y mayor deshidratación. El pH de la carne fue más alto en los dos músculos para el grupo que estuvo esperando 3 h. El incremento de tiempo de espera afecta al bienestar del animal pero no a la calidad de la carn

Efecto de los grados día de ayuno y del hacinamiento previos al sacrificio sobre el contenido estomacal y respuesta de estrés en trucha arcoíris (Oncorhynchus mykiss)

El ayuno pre-sacrificio es una práctica rutinaria en acuicultura que se lleva a cabo para vaciar el aparato digestivo disminuyendo la cantidad de heces y previniendo una contaminación de la canal (Robb, 2008). Sin embargo, el ayuno puede también incrementar los niveles de estrés de los peces y si estos son lo suficientemente altos afectan a la calidad de la canal (Poli et al., 2005)

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Physio-metabolic response of rainbow trout during prolonged food deprivation before slaughter

Fish normally undergo periods of food deprivation that are longer than non-hibernating mammals. In aquacultured rainbow trout (Oncorhynchus mykiss), it is unclear how fasting may affect their physiological adaptative response, especially when they are normally fed daily. In addition, that response may vary with temperature, making it necessary to express fasting duration in terms of degree days. In the current study, trout were fasted for 5, 10, and 20 days (55, 107, and 200 degree days (°C d), respectively). To assess the physiological response of fish to fasting, different biometric, blood, plasma, and metabolic parameters were measured, as well as liver fatty acid composition. The fish weight, condition factor, and the hepato-somatic index of 5-day fasted trout were not significantly different from those of control fish. Gastric pH increased as fasting progressed while plasma concentrations of glucose, triglycerides, and total proteins decreased significantly after 10 days of fasting, while the percentage of non-esterified fatty acids increased. There were no significant differences in plasma ions (sodium, potassium, and calcium), except for chloride ion which decreased after 5 days of fasting. Liver glycogen decreased after 5 days of fasting while glycogen concentration in muscle did not decrease until 20 days of fasting. Liver color presented a higher chroma after 5 days of fasting, suggesting a mobilization of reserves. Finally, acetylcholinesterase activity in the brain was not affected by food deprivation but increased after 10 days of fasting in liver and muscle, suggesting the mobilization of body reserves, but without severely affecting basal metabolism
