“…Dalmau et al (2009) assessed the pre-slaughter handling in 10 slaughterhouses and noted that the majority of the assessed animals were classified as score 1, confirming with the values found in this experiment. Bünger et al (2015) when comparing females, castrated males and uncastrated males noticed that the uncastrated animals presented a higher incidence of skin lesions in the score 1 and 2.…”

A non-surgical sterilant (NSS) was used with the objective of assessing the zootechnical performance, carcass and meat quality, and hormone levels. 90 male piglets were selected with birthweights varying between 1.5kg to 2.0kg. The control group was constituted of 45 males castrated by the conventional surgical method, at the seventh day of age, and the treated group was constituted of 45 males castrated with NSS (active principle of zinc gluconate in the concentration of 26.2mg/mL associated to the dimethyl sulfoxide at 0.5%), with the application of the first dose on the seventh day of age and the second dose on the fourteenth day of age. The zootechnical assessments were carried out on the farm and consisted: weight gain in the periods per animal and feed conversion. The slaughter of the animals and the assessment of the carcass and meat quality and hormone levels were carried out in a slaughterhouse and the municipality of Campinas (SP). The study demonstrated that the use of NSS was a viable alternative in relation to the zootechnical performance and the carcass quality. In relation to the meat quality there was no significant difference in the majority of the assessed parameters.Keywords: swine, zinc gluconate, androstenone, feed conversion, carcass yield RESUMO Foi utilizado esterilizante não cirúrgico (ENC) com

“…Despite this, few studies have examined skin lesion prevalence, particularly in an animal welfare context (Nielsen et al, 2014). Skin lesions are a concern as they can reflect poor social and physical environments (Dalmau et al, 2009). Indeed, along with tail lesions, skin lesions were recently deemed to be one of the most important indicators of pig welfare status by a panel of international animal welfare experts (European Food Safety Authority, 2012).…”

There is increasing interest in developing abattoir-based measures to assist in determining the welfare status of pigs. The primary aim of this study was to determine the most appropriate place on the slaughter line to conduct assessments of welfare-related lesions, namely apparent aggression-related skin lesions (hereafter referred to as 'skin lesions'), loin bruising and apparent tail biting damage. The study also lent itself to an assessment of the prevalence of these lesions, and the extent to which they were linked with production variables. Finishing pigs processed at two abattoirs on the Island of Ireland ( n = 1950 in abattoir A, and n = 1939 in abattoir B) were used. Data were collected over 6 days in each abattoir in July 2014. Lesion scoring took place at two points on the slaughter line: (1) at exsanguination (slaughter stage 1 (SS1)), and (2) following scalding and dehairing of carcasses (slaughter stage 2 (SS2)). At both points, each carcass was assigned a skin and tail lesion score ranging from 0 (lesion absent) to 3 or 4 (severe lesions), respectively. Loin bruising was recorded as present or absent. Differences in the percentage of pigs with observable lesions of each type were compared between SS1 and SS2 using McNemar/McNemar-Bowker tests. The associations between each lesion type, and both cold carcass weight and condemnations, were examined at batch level using Pearson's correlations. Batch was defined as the group of animals with a particular farm identification code on a given day. The overall percentage of pigs with a visible skin lesion (i.e. score > 0) decreased between SS1 and SS2 ( P < 0.001). However, the percentage of pigs with a severe skin lesion increased numerically from SS1 to SS2. The percentage of pigs with a visible tail lesion and with loin bruising also increased between SS1 and SS2 ( P < 0.001). There was a positive correlation between the percentage of carcasses that were partially condemned, and the percentage of pigs with skin lesions, tail lesions and loin bruising ( P < 0.05). In addition, as the batch-level frequency of each lesion type increased, average cold carcass weight decreased ( P < 0.001). These findings suggest that severe skin lesions, tail lesions and loin bruising are more visible on pig carcasses after they have been scalded and dehaired, and that this is when abattoir-based lesion scoring should take place. The high prevalence of all three lesion types, and the links with economically important production parameters, suggests that more research into identifying key risk factors is warranted.Keywords: animal welfare, carcass condemnation, pigs, skin lesions, tail lesions ImplicationsAnimal welfare assessment at abattoirs has several advantages over traditional farm-based assessments. However, the extent to which routine carcass processing either masks or enhances the visibility of key welfare lesions is unclear. This research has confirmed that the visibility of loin bruising and tail lesions is improved by scalding and dehairing of carcasses. Mild app...

“…Some previous studies, carried out in different scenarios, have used the Welfare Quality protocol to assess welfare of cattle and other farm species (Dalmau et al, 2009;Temple et al, 2011;Kirchner et al, 2014). Nevertheless, to our knowledge, this is the first scientific study reporting in detail the cattle welfare status in different ISPS using this methodology.…”

Welfare of cattle kept in intensive silvopastoral systems: A case report

et al. 2017

-The objective of this research was to evaluate the effect of three different intensive silvopastoral systems (ISPS) on cattle animal welfare (AW) in Colombia. The three ISPS differed in area, plant composition, and grazing periods as follows: ISPS1 -low plant diversity in paddocks of 1200 m 2 , with grazing period of 24 h; ISPS2 -middle plant diversity in paddocks of 600 m 2 , with grazing period of 12 h; and ISPS3 -high plant diversity in paddocks of 600 m 2 , with grazing period of 24 h. Animal welfare was assessed using a wide range of criteria, which were integrated using L-spline functions and Choquet integrals to generate overall values. It was found that AW was good in all ISPS; the highest scoring criteria was for food and water, with 99, 97, and 100 points from a maximum of 100 for ISPSs 1, 2, and 3, respectively. Comfort showed values of 100 for all three systems, but good health was the most problematic criteria of the AW features with scores of 25, 40, and 36 for ISPSs 1, 2, and 3, respectively. All three ISPS showed excellent scores for appropriate behavior (82, 88, and 89). The welfare problems shown here were not specific to the individual ISPS, but were common to all livestock systems in the region. Despite the differences in diversity of plants, size of paddocks, and grazing period among the three ISPSs tested, all of them provide cattle with sufficient resources and a diverse environment, ensuring a good state of welfare to them.
