O estudo foi realizado em abatedouros localizados no estado de São Paulo, no período de janeiro a fevereiro de 2009. Foram colhidas 292 amostras, oriundas de locais considerados críticos do abatedouro, como gaiolas de transporte, água do tanque de escalda, depenadeiras, área de evisceração, água dos tanques de pré- resfriamento e resfriamento e setor de embalagem (carcaça e partes prontas para comercialização). No abatedouro A, 30 amostras foram positivas (18,7%), sendo as depenadeiras o local onde mais isolou-se Salmonella spp. e no abatedouro B, 74 amostras positivas (56,1%), sendo as gaiolas e a área de evisceração e depenadeiras os locais mais contaminados. Os sorovares mais detectados foram S. Albany, S. Infantis e S. Schwarzengrund, S. Kentucky / The following research evaluated the level of contamination by Salmonella spp. In two poultry slaughterhouses with different inspection systems – SIF (service of federal inspection) and SISP (service of inspection of state Sao Paulo). The study was carried out in slaughterhouses located in the state of Sao Paulo, in the period of January to February of 2009. It was gathered a total of 292 samples, from the critical points of the slaughterhouses: transport cages, water from the scalding tank, plucking machines, evisceration, water from tanks of pre-cooling and cooling and packaging sector with samples of final products. The slaughterhouse A 30 samples were positive (18,7%), being the most contaminated the plucking machine and on slaughterhouse B 74 samples were positive (56,1%), being the cages, evisceration and the plucking machines the most contaminated. The serotypes most detected were S. Albany, S. Infantis e S. Schwarzengrund, S. Kentucky

Official veterinarians (OVs), employed by the National Food Administration of Sweden, are responsible for the monitoring of animal welfare as well as food hygiene procedures in the country ́s slaughterhouses. In 2014, the National Food Administration of Sweden introduced new policy guidelines to ensure that the OVs report all deviations to the County Administrative Boards of Sweden, which are responsible for welfare inspections in Sweden. Therefore, it is important that the OVs notify the administrative boards if they have any suspicions regarding animal neglect. The overall aim of this study is to investigate the cooperation between the County Administrative Boards of Sweden and the National Food Administration of Sweden, and to find out how this collaboration impacts animal welfare. In addition to this, its second aim is to explore the current state of animal welfare in slaughterhouses in southern Sweden. This study is based on a qualitative research method, which combines questioners with the analysis of publicly available documents. Furthermore, this study shows that although the new guidelines have resulted in heavier workloads, both parties are satisfied with the arrangement and agree that the new procedures have led to an improvement of animal welfare. In 2015, OVs in Skåne, Blekinge, Halland and Kronoberg submitted 506 cases of suspected animal cruelty taken place in these counties to the County Administrative Boards of Sweden. After comparison of the total number of reports from 2015 and the overall animals slaughtered in the counties in 2014, this study highlights that 0,03 % of all lambs, 0,12 % of all swine and 0,01 % of all cattle were reported with deviations during slaughter. Therefore, this study concludes that animal welfare in slaughterhouses can be considered to be of a high standard. / Sverige anses i många avseende vara ett föregångsland när det kommer till djurskydd och djurvälfärd. En betydelsefull del av den svenska djurskyddskontrollen utgörs av s.k. officiella veterinärer vilka är speciellt förordnade av Livsmedelsverket att kontrollera livsmedelshygien så väl som djurhälsa och djurskydd ute på våra svenska slakterier. Alla våra produktionsdjur som är ämnade att bli livsmedel har sin sista anhalt vid ett slakteri, vilket gör de officiella veterinärernas och assistenternas roll mycket betydelsefull. Under vintern 2013 slog media larm om att avvikelser som uppmärksammats i samband med slakttransporter inte alltid rapporterades vidare till länsstyrelsen i den utsträckning de borde. Året därefter infördes en nyordning från Livsmedelsverkets sida och idag följer de officiella veterinärer nya riktlinjer gällande hur denna vidarerapportering ska gå till. För att bristerna som uppdagats vid slakt ska följas upp och utredas är det viktigt att informationen når länsstyrelsen för vidare handläggning. De officiella veterinärerna ska därför, enligt de nya riktlinjerna, meddela länsstyrelsen om alla uppmärksammade brister i djurskyddet vid slakt genom en “underrättelse om djurskydd”. Ett gott samarbete mellan länsstyrelsen och Livsmedelsverket är därmed väsentligt för att avvikelser i djurhållningen inte ska gå obemärkta förbi. Syftet med denna studie var dels att beskriva hur samarbetet mellan Livsmedelsverket och länsstyrelsen fungerar i Skåne, Halland, Blekinge samt Kronoberg och vilken inverkan det har på djurskyddet vid slakt. Den andra delen av studien berör hur djurvälfärden vid slakt ser ut utifrån vilka avvikelser som uppdagats under 2015 och underrättats till länsstyrelsen i respektive län. Undersökningen genomfördes med en kvalitativ metod och inleddes med att samtliga underrättelser om djurskydd som upprättats under 2015 i fyra angränsade län i södra Sverige begärdes ut från Livsmedelsverket. För att få svar på hur samarbetet mellan Livsmedelsverket och länsstyrelsen fungerar skickades två frågeformulär ut till sakkunnig personal inom området; ett till Livsmedelsverkets officiella veterinärer i södra Götaland och ett till verksamma djurskyddshandläggare i de berörda länen som ansvarar för handläggning och uppföljning av inkomna djurskyddsärenden vid slakt. De befintliga rutinerna och riktlinjer som följs i dagsläget har lett till en ökad arbetsbelastning för båda parter och under 2015 inkom sammanlagt 506 underrättelser till Länsstyrelsen i Skåne, Halland, Blekinge och Kronoberg. Trots att arbetsbördan har ökat anser både länsstyrelsen och Livsmedelsverket i södra Sverige att samarbetet och kommunikationen mellan parterna har förbättrats sedan nyordningen infördes. Vid jämförelse mellan antalet slaktade djur 2014 och andelen djur som noterats med avvikelser 2015 i de fyra länen erhölls en procentuell siffra på den totala andelen djur som noterats med avvikelser vid slakt. Resultatet blev 0,03 % för får/lamm, 0,12 % för slaktsvin och suggor och 0,01 % för nötkreatur. Resultatet indikerar på en god djurvälfärd vid slakt hos våra produktionsdjur i södra Sverige. För att få djupgående kunskaper om effektiviteten i länsstyrelsens och Livsmedelsverkets samarbete bör även djurhållares och transportörers upplevelser tas i beaktande i framtida studier.

In the studies described in this thesis the amounts of Ca, P and Mg retained by growing lambs were determined following the slaughter of the lambs and their analysis. In experiment 1, the effects of growth rate on body composition and mineral retention were studied. The lambs were grown at different rates from 24 kg to 50 kg live-weight. The composition of empty-body gain (EBG) was estimated based on an initial slaughter group at the beginning of the trial. Fast growing lambs contained more fat and less protein, ash, Ca and P than slow growing ones. However, in the fat-free empty-body (FFEB), there were no significant differences found attributable to growth rate, except for Mg which was decreased with slow growth. Supplementary CaCO<SUB>3</SUB> significantly increased ash, Ca and P retention in FFEB of the fast growing lambs. In experiment 2, the retention of minerals from lambs fed either forage or concentrate diets was studied. Three groups of 8 Suffolk x Blackface wether lambs were (a) allowed to graze the grass outdoors (b) fed-concentrate indoors and (c) fed grass indoors. The lambs were grown from 24 kg and slaughtered at about 40 kg live = weight over 100 days. Retentions of Ca and P in empty-body gain (EBG) and fat-free empty-body gain (FFEBG) were significantly higher in grass-fed lambs. Higher mineralisation in the latter group was attributed to differences in acid-base balance between the diets and was not a function of either exercise or sunlight. Experiment 3 was designed to re-assess the requirements of Ca and P for growing lambs. Four groups of 10 Suffolk x Blackface lambs were fed concentrate diets containing different concentrations of Ca and P over a 93 day experimental period. Lambs fed on normal Ca-normal P diet (based on TCORN's (1988) new estimate) appeared to meet their requirement. Lambs fed on high Ca-high P diet showed no increase in mineral retention while those on low Ca-low P diet were more poorly mineralised. A high Ca-low P group had low concentration of P in blood and rumen liquor. Radiographic studies of the metacarpus and metatarsus from these trials were of limited value in predicting the mineral content of the empty-bodies of lambs.

This thesis describes experimental work conducted to define factors associated with the occurrence of ecchymosis (blood splash) in fallow deer, and discusses facets of the Australian venison processing sector with respect to its capacity to improve the quality of venison. Data was collected on 1804 deer slaughtered experimentally (n equals 494) or at commercial works (n equals 1310) in a range of different slaughter systems. The study showed that a number of factors contribute to the expression of ecchymosis in the carcases of slaughtered deer, and the tailoring of slaughter procedures to suit particular slaughter systems is likely to reduce the extent to which ecchymosis occurs. / Doctor of Philosophy (PhD)
