“…No factors appeared to be statistically significant in the logistic regression analysis in which the outcome variables were 'sudden death' and 'euthanasia'. That 'lameness' was not significantly associated with euthanasia disagrees with other studies, which have found lameness to be the most commonly observed reason for euthanasia among sows and gilts (Kirk et al, 2005;Engblom et al, 2008). As herds in this study were visited twice by technicians who performed clinical registrations on individual sows, they could have made farmers more aware of clinical signs of lameness.…”

“…Among 14 526 culled sows in 37 Danish sow herds with group-housed pregnant sows, 10% of the sows were euthanized and 11% died suddenly (Vestergaard et al, 2006). Problems in relation to the locomotion system (such as arthritis and osteochondosis) are reported to be the most common reason for euthanizing sows in systems with group-housed pregnant sows (Kirk et al, 2005;Engblom et al, 2008). Kirk et al (2005) found locomotive disorders to be the primary cause of euthanization in more than 70% of 172 euthanized sows examined post mortem.…”

Sows suffering from clinical signs of disease (e.g. lameness, wounds and shoulder ulcers) are often involuntarily culled, affecting the farmer's economy and the welfare of the animals. In order to investigate the interrelationships between clinical signs of individual pregnant group-housed sows, we performed an explanatory factor analysis to identify factors describing the patterns of variation of clinical signs. Moreover, we investigated how these emerging factors affected the probability of a sow to be either (i) euthanized, (ii) suddenly dead, (iii) sent to slaughter due to clinical signs of disease such as claw lesions or wounds or (iv) involuntarily culled (representing a pool of sows that were either euthanized, dead or sent to slaughter due to disease). Data from 2.989 pregnant sows in group-housing systems from 33 sow herds were included in the study. A thorough clinical examination was performed for each sow by using a protocol including 16 different clinical signs. Farmers recorded all cullings and deaths and the reasons for these actions in a 3-month period after the clinical examination. Among the observed sows, 4.2% were involuntarily culled during the 3-month period. From the explanatory factor analysis, we identified three factors describing the underlying structure of the 16 clinical variables. We interpreted the factors as 'pressure marks', 'wounds' and 'lameness' Logistic analyses were performed to investigate the effect of the three factors and the parity number of each sow on the four outcomes: (i) euthanized, (ii) suddenly dead, (iii) sent to slaughter due to clinical signs of disease and (iv) involuntarily culled. The analyses showed that 'lameness' significantly increased the risk of sows to be involuntarily culled (P 5 0.016) or sent to slaughter due to clinical signs of disease (P 5 0.026). Lameness is generally considered to be an important welfare problem in sows, which could explain the increased risk seen in this study. By contrast, 'pressure marks' and 'wounds' did not have any significant effect on the four outcomes (P . 0.05).

“…El tamaño y la cantidad de quistes presentes en cada ovario son variables, pudiendo ser grandes o pequeños, múltiples o simples y uni o bilaterales. En estudios realizados mediante ultrasonografía de tipo B (USG-B), la prevalencia de QOv varió entre el 2 % y el 30 % en el animal vivo (Cianciolo & Mohr, 2007), mientras que en estudios realizados en planta de faena fue de 7 % a 13 % (Barrales et al, 2014;D´Allaire et al, 2006;Engblom et al, 2008;Heinonen et al, 1998;Knauer et al, 2007;Rodríguez et al, 2008;Tummaruk et al, 2009).…”

Resumen: La evaluación de los registros reproductivos y de las causas de descarte en reproductoras porcinas es una herramienta imprescindible para aplicar estrategias de descarte eficaces y lograr una mayor eficiencia productiva. Esto se debe al impacto económico y productivo que representan la compra y preparación de nuevas reproductoras. Las limitaciones que presenta el examen clínico reproductivo en la hembra porcina hace necesaria la aplicación de herramientas que permitan dar un enfoque más objetivo a las políticas y decisiones de descarte reproductivo. Entre las herramientas que se pueden considerar se incluyen: el análisis de registros reproductivos individuales y poblacionales, la evaluación de longevidad en reproductoras y la inspección del aparato genital en planta de faena. Palabras clave: cerda, descarte, registros reproductivos, aparato genitalAbstract: The evaluation of reproductive records and culling reasons in sows is essential to implement effective removal strategies and obtain greater efficiency. This is due to the economic and productive impact represented by the costs of purchasing and preparing new gilts. The anatomical restrictions for a reproductive clinical examination in sows require other tools, such as evaluation of reproductive records, sow longevity and inspection of the genital tracts at the slaughterhouse in order to give more objective approach regarding the breeder removal policies and decisions.

“…In some cases, euthanasia may be the best option for the well-being of the pig 11) . In Sweden, euthanasia has been well practiced because of the animal welfare legislation, which states that only females in normal body condition and without lameness are allowed to be transported to slaughter 6) . In fact, the proportion of euthanized sows on commercial farms was 10.5 , which was higher than the 4.3 of dead sows 5) .…”
