BackgroundApproximately 50% of sows are slaughtered each year, but management of cull sows is not well described.MethodsWe aimed to describe how cull sows are sent to slaughter using a questionnaire survey emailed to 885 Danish pig farmers, including questions about the use of pick-up facilities (either a designated pen used for reasons of biosecurity and practicality, in a special part of the barn, where pigs are kept in the last hours before being loaded onto a commercial truck, or a stationary vehicle kept outside the buildings and used for the same purpose) and evaluation of fitness for transport.ResultsA total of 360 farmers answered all questions, constituting a homogeneous group of middle-aged, experienced males. The management of the sows seemed rather variable, for example regarding choice of pick-up facility, its available resources, actions taken when sows were not fit for transport and sow conditions leading to doubt about fitness for transport. Special condition transport was only reported rarely, and rejection of sows due to lack of fitness for transport, by drivers or veterinarians at the slaughterhouse, was only rarely experienced.ConclusionThese findings may be used for formulation of hypotheses for future studies in this area characterised by welfare challenges, potentially leading to science-based recommendations relevant for animal welfare, productivity and biosecurity.

Cull Sows

The carcass weight distribution of the cull sow population was evaluated from 104 456 sows slaughtered in Ontario in 1988. Carcass weight, backfat depth and loin muscle depth were evaluated for 797 additional sows, randomly selected at a commercial abattoir. Approximately 85% of sows were between 100 and 200 kg with 4.5% less than 100 kg and 10.5% more than 200 kg carcass weight. The frequency distribution showed backfat depth was most frequently between 15 and 19.9 mm (26.73%) and 20 and 24.9 mm (29.99%). Sow carcasses are extremely diverse, varying 3- to 9-fold in backfat depth and 2- to 3-fold in loin muscle depth within any 25-kg weight class. Key words: Sows, carcass composition, backfat

AbstractSow culling is an essential practice in swine herds to optimize animal health and productivity; and cull sows represent a considerable proportion of the herd at any given time point. Even though recent studies have reported that the microbiome is associated with susceptibility to diseases, the microbiome in the cull sow population has not been explored. The main objective of this study was to investigate whether there were differences in abundance and diversity of microbes encountered in the gut and upper respiratory tract of sows of different health status (healthy, cull, and compromised cull sows) and different farms. Farms were visited once, 30 individual fecal and nasal swab samples were obtained per farm; and pooled across animals by health status and farm in pools of five. Genomic DNA was extracted and samples were subjected to MiSeq 16S rRNA sequencing using Illumina MiSeq. Diversity analyses were conducted using QIIME. Alpha diversity was analyzed using observed OTUs, PD Whole Tree, and Chao1; and beta diversity was assessed using weighted UniFrac. The mean number of OTUs was 3,846.97±9,078.87 and 28,747.92±14,090.50 for nasal and fecal pooled samples, respectively. Diversity of the nasal microbiota was low compared to the gut microbiota. For nasal samples, there was a difference in diversity between samples from farms 1-6 using the Chao1 metric (p = 0.0005); and weighted beta diversity values indicated clustering by health status. For fecal samples, there was no difference in diversity between compromised, cull, and healthy sows; or between samples from farms 1-6. Weighted PCoA analyses showed an influence of farm of origin on the diversity of pooled fecal samples. Finally, differences at the genus level were found in the fecal microbiota composition of sows of different health status and farm of origin; but not for nasal microbiota.

The goal of this study was to determine the prevalence of Listeria monocytogenes in sows slaughtered at a single Midwestern plant on two occasions (trial 1, n = 179 sows; trial 2, n = 160 sows). Fecal samples collected antemortem (trial 1) as well as animal tissues, and carcass swabs collected at the abattoir (trials 1 and 2) were analyzed. Eight isolates of L. monocytogenes were recovered from five samples that represented 0.18% of the total samples (n = 2,775). In trial 1, L. monocytogenes was detected in a tonsil sample (0.6%; 1 positive of 181 tonsils), in a carcass (0.6%; 1 positive of 179 carcasses), which was sampled prior to the organic rinse, and in two chopped meat block samples (1.2%; 2 positive of 165 samples). In trial 2, L. monocytogenes was only detected in a single chopped meat block sample (0.15%; 1 positive of 688 total samples). These data indicate the low prevalence of L. monocytogenes in the cull sow.
