AB  - BACKGROUND This investigation provides an important insight into Eurasian consumers' food safety beliefs and trust issues influenced by the COVID-19 pandemic. An online survey was conducted in 15 European and Asian countries involving more than 4000 consumers. RESULTS It has confirmed that different socioeconomic characteristics, cultural aspects and education levels shape food safety perceptions within Eurasian countries. The COVID-19 pandemic influenced their beliefs and trust in food safety, which is relatively low on average. However, it is significantly higher for European consumers (especially European Union ones) compared to their Asian counterparts. Both Asian and European respondents agreed that food fraud and climate changes represent a food safety issue. However, European consumers were less concerned regarding the food safety of genetically modified foods and meat and dairy analogs/hybrids. Asian consumers were, to a greater extent, worried about the risk of getting COVID-19 from food, restaurants, food retail establishments and home food deliveries. CONCLUSION Eurasian consumers have put their greatest extent of trust, when food safety assurance is concerned, into food scientists and food producers holding a food safety certificate. Broadly, they are uncertain to what extent their federal governments and food inspectors are competent, able and efficient in ensuring food safety. Higher education of Eurasian consumers was followed by increased food safety confidence in all parts of the food chain. © 2023 The Authors.

AB  - In this review paper, hygienic procedures before, during and after cow milking are discussed. The procedures for maintaining hygienic udders before and after milking, as well as maintaining the hygiene of milking units are described. The description includes the maintenance of milker's hand hygiene, udder disinfection and udder disinfection after milking. It is pointed out that these milking procedures should be carried out in a clean environment and without any disturbance to cows. In addition, the need to control the implementation of these hygiene measures is emphasized. A proper way of carrying out the hygienic procedures essentially contributes to reduction of the number of microorganisms and the number of somatic cells in milk, the frequency of occurrence of mastitis, which significantly affects quality of milk and health of milking cows.

Ističe se da se ovi postupci
kod muže treba da odvijaju u čistom okruženju i bez uznemiravanja krava. Pored toga, navodi se i potreba kontrole sprovođenja tih higijenskih postupaka. Pravilan način sprovođenja ovih higijenskih procedura suštinski doprinosi smanjenju broja mikroorganizama i broja somatskih ćelija u mleku, učestalosti pojave mastitisa, što značajno utiče na kvalitet mleka, kao i opšte zdravstveno stanje krava muzara.

AB  - The Total Bacterial Count (TBC) and the Somatic Cells Count (SCC) in the milk are important indicators of its hygiene and quality. Hygienic conditions in barns, milking procedures, udder hygiene before, during and after milking, milking machine hygiene, as well as milk cooling procedures immediately after milking, have direct or indirect influences on milk hygiene indicators. Poor results of milk hygiene quality, when it comes to SCC and TBC, which are often seen in dairy cattle farms in our country, indicate numerous omissions before and during milking. To determine the possibility of improving milk hygiene quality, training of extension service professionals and farmers was conducted, corrective and preventive measures were determined and the achieved state was monitored on 128 dairy farms where SCC and TBC were observed at regular monthly intervals for 6 months. The results showed a continuous statistically very significant improvement in hygienic conditions in barns, milking procedures, udder hygiene before, during and after milking, milking machine hygiene, as well as milk cooling procedures. This has contributed to a statistically very significant improvement in the hygienic quality of milk, both in SCC and TBC indicators, continuously from month to month, with a visible improvement at the end related to the beginning of the study period. At the begining and the end of survey 19.7% and 50.0% of milk samples belong to 1st class of milk quality, respectively, indicating a significant improvement after implementation of corrective measurements.

AB  - Male piglets are castrated primarily to avoid the unpleasant boar taint in meat, and additionally for the predisposition of castrates to accumulate fat and for their lower risk of developing unwanted behaviours. There are two main strategies available for withdrawing from surgical castration: one is immunocastration and the other is to raise entire male pigs or boars. Additionally, raising intact boars is more profitable because of the production of carcasses with lean meat and better feed conversion. Boars (compared to castrates) exhibit more aggressive, sexual, damaging social behaviour and reduced feeding behaviour with a lower prevalence of sickness behaviour as a result of good health and low susceptibility to chronic inflammation. In this review, the behaviours specific for boars as a result of sexual maturity are reviewed, with an overview of differences in the behaviour of surgically castrated barrows, immunocastrates and boars reared in group-housed systems. The raising of boars allows for good welfare of these animals in early life, but later, on reaching sexual maturity, the welfare of boars can be diminished because of their propensity to aggression and more mounting behaviour than castrates. Innovations in the breeding and management of boars are needed to improve their performance and to reduce welfare implications of these animals raised in social groups, and in particular to minimize deviant behaviours towards pen mates.

AB  - Simple Summary A survey was conducted with 5508 consumers from 13 Eastern European countries. Three clusters of consumers were identified: one with consumers indifferent towards animal welfare; one with consumers concerned about animal welfare, but they believe it is difficult to achieve; and one with consumers concerned about animal welfare, and they believe it is possible to achieve it. The aim of this exploratory work, because of the existing bias on the size of the sample and some of the sociodemographic characteristics of the participants, was to investigate the Eastern European consumers' beliefs and attitudes toward animal welfare, to perform a cross-country segmentation analysis and to observe possible differences with their Western European counterparts. For this purpose, a survey was conducted with 5508 consumers from 13 Eastern European countries (Bosnia and Herzegovina, Bulgaria, Czech Republic, Croatia, North Macedonia, Hungary, Moldova, Poland, Romania, Serbia, Slovakia, Slovenia, and Ukraine) using a questionnaire with nine statements about consumers beliefs regarding animal welfare (aspects of management, ethical issues about animals, and consequences of animal welfare on meat quality and price), one statement about the willingness to pay more for meat produced under better welfare conditions, and four statements regarding attitudes toward animal welfare. Differences between countries were detected for all the statements. Moreover, three clusters of consumers were identified: one with consumers indifferent towards animal welfare; one with consumers concerned about animal welfare, but they believe it is difficult to achieve; and one with consumers concerned about animal welfare, and they believe it is possible to achieve it.

Moreover, three clusters of consumers were identified: one with consumers indifferent towards animal welfare; one with consumers concerned about animal welfare, but they believe it is difficult to achieve; and one with consumers concerned about animal welfare, and they believe it is possible to achieve it.",

AB  - In this review paper, contradictions in modern livestock production as dilemmas of farm animal welfare are considered. The main dilemma concerns the question of whether extensive production in small farms is generally better than intensive production in large farms. The next dilemma relates to an intensive selection of animals and its impact on the emergence of welfare problems. Another dilemma is related to the two main interconnected problems of pig welfare in individual farrowing pens: the piglet death by crushing and the sows' movement restriction. Similarly, welfare dilemma is the paradox of parent flocks of broiler line breeding that could not be solved until the pressure for genetic advancement in production is required due to the economic efficiency. The next example of the dilemma is the widespread practice of tail docking in piglets in order to reduce the risk of tail biting. Although the tail docking is painful and may cause death, anaesthesia is usually not applied on farms. A similar example of the dilemma is debeaking in the laying hens and the occurrence of feather pecking in free rearing systems. It is important to notice the difference between the described dilemmas, where one premise opposes the other, which is essentially a conflict between the animal welfare goals and other values, such as economic, ethical and moral issues. Finally, there are also some dilemmas about the consumers' willingness to pay a higher price of products that originate from welfare friendly rearing conditions.
AB  - U ovom preglednom radu razmatraju se kontradikcije u modernoj stočarskoj proizvodnji kao dileme koje se odnose na dobrobit farmskih životinja. Glavna dilema odnosi se na pitanje da li je ekstenzivna proizvodnja na malim farmama generalno bolja od intenzivne proizvodnje na velikim farmama. Sledeća dilema odnosi se na primenu intenzivne selekcije životinja i njen uticaj na nastanak problema dobrobiti. Naredna dilema se odnosi na dva glavna međusobno povezana problema dobrobiti svinja u pojedinačnim boksovima za prašenje: uginuća prasadi gnječenjem i ograničenje kretanja krmača. Takođe, dilema u vezi sa dobrobiti je paradoks roditeljskih jata tovnih pilića koja se ne može rešiti dok postoji pritisak za genetski napredak u proizvodnji zbog ekonomske efikasnosti. Sledeći primer dileme je široko rasprostranjena praksa sečenja repa kod prasadi kako bi se smanjio rizik od griže repova. Iako je sečenje repa bolno i može prouzrokovati uginuće, anestezija se obično ne primjenjuje na farmama. Sličan primer dileme je i skraćivanje kljuna kod kokoši nosilja i pojava kljucanja perja u sistemima slobodnog uzgoja. Važno je uočiti razliku između opisanih dilema, gde je jedna premisa suprotstavljena drugoj, što je u suštini konflikt između ciljeva dobrobiti životinja i drugih aspekata, kao što su ekonomska, etička i moralna pitanja. Konačno, postoje i neke dileme koje se odnose na spremnost potrošača da plate višu cenu za proizvode koji su dobijeni u uslovima gajenja koji pospešuju dobrobit farmskih životinja.

AB  - A cross-sectional longitudinal survey was carried out between February 2009 and January 2010 to evaluate udder-related risk factors for clinical mastitis occurring in dairy herds. Data were used from three dairy farms. Research was divided into four calendar seasons. Cows with clinical mastitis were detected by clinical examination of the udder and determination of abnormalities in milk. Udder level variables, conformation characteristics of udder and teats and teat end to floor distances were included in the logistic regression analysis. The estimated incidence risk for CM in the population of dairy cows observed was 85.02 cases per 100 cow-years at risk. The relative risk of CM was lower for primiparous cows, and increased with further parity. The median number of days in milk at diagnosis was 108 days, ranging from a median of 55 to 150 days in lactation. The rear udder quarters had a higher risk of CM incidence compared to the front udder quarters. A Chi square test revealed that farm management and cow parity were significantly connected with incidence of clinical mastitis. Spring was the season with the highest percentage of diagnosed cases of CM, with the exception of farm A, where Fall was the season with the highest percentage of cases. All udder level factors entered in the models were significantly linked with the occurrence of CM. The odds ratio of CM increased significantly as udder morphology worsened, teat ends were flat and the distance from teat ends to floor decreased. It was concluded that conformation udder traits could be used for the genetic selection of dairy cows for mastitis resistance.

AB  - The purpose of this study is the determination of the occurrence and prevalence of clinical mastitis and lactation incidence risk on three dairy farms. A one year study on a total of 1031 black-white breed cows with a total of 1267 lactations was performed. Each dairy farm implemented a different technology of rearing and was of different herd size (farm A - tie-stalls, 162 cows; farm B - loose-housing system with open shed and deep bedding, 357 dairy cows; and farm C - loosehousing system with enclosed shed, 512 cows). Clinical mastitis in cows was detected by clinical examination of the udder and determination of abnormalities in the milk. To distinguish two consecutive cases of clinical mastitis within the same lactation a time period of nine days was used. Annual prevalence rate of clinical mastitis for the entire population of cows was 34.13% on cow level, and 30.07% on lactation level. There was a high prevalence rate of clinical mastitis in primiparous cows, 21.43%, 40.77% and 12.55%, on farms A, B and C, respectively. Lactation incident risk for cows on farm A was 25.00%, farm B 95.58% and farm C 21.49%. The prevalence of clinical mastitis and lactation incidence risk tended to increase with increasing parity. The annual lactation risk for the entire population of cows was 45.86%. All indicators for the determination of the occurrence of clinical mastitis in dairy farms, which were observed during the research, showed the greatest values on farm B. Most of the cows manifested one (68.24%) or two (18.63%) cases of clinical mastitis during lactation. There was a long period in lactation until the appearance of the first case of clinical mastitis (112.21 ± 92.04 days). Generally, clinical mastitis was registered during the whole period of the survey, with some fluctuations between different seasons. The method of GLM (General Linear Model), univariate procedure, was used to analyze associations between the incidence of clinical mastitis and farm management, parity of cows and season of the year. Pearson's coefficient of correlation was performed for analysis of interdependence on variables in the model. There was statistical significance (p lt 0,001) between the season and incidence of clinical mastitis.
AB  - Cilj ovog rada je bio utvrđivanje pojave i prevalencije kliničkog mastitisa i laktacionog rizika na tri farme mlečnih krava. Sprovedena su jednogodišnja istraž ivanja na ukupno 1031 kravi crno bele rase i u 1267 laktacija. Farme su se međusobno razlikovale po tehnologiji gajenja i veličini stada (farma A - vezani sistem gajenja, 162 krave; farma B - slobodni sistem gajenja na dubokoj prostirci u otvorenoj staji, 357 krava i farma C - slobodni sistem gajenja u zatvorenoj staji, 512 krava). Utvrđivanje kliničkog mastitisa vršeno je kliničkim ispitivanjem vimena i utvrđivanjem promena u mleku. Da bi se napravila razlika između dva uzastopna slučaja kliničkog mastitisa u toku iste laktacije korišćen je period od 9 dana. Godišnja učestalost kliničkih mastitisa za celokupnu populaciju krava iznosila je 34,13 % u odnosu na ukupan broj krava i 30,07% u odnosu na ukupan broj laktacija. U toku istraživanja utvrđena je visoka prevalencija kliničkog mastitisa kod primiparnih krava i to 21,43%, 40,77% i 12,55% na farmama A, B i C, redom. Opseg laktacionog rizika za krave na farmi A iznosio je 25,00%, farmi B 95,58% i na farmi C 21,49%. Prevalencije kliničkog mastitisa i laktacionog rizika pokazuju tendenciju rasta sa povećanjem pariteta krava. Godišnji laktacioni rizik za celokupnu populaciju krava iznosio je 45,86%. Svi indikatori pojave kliničkog mastitisa u istraživanju pokazali su najveće vrednosti na farmi B. Sa povećanjem pariteta ili uzastopne laktacije utvrđeno je povećanje prevalence i laktacionog rizika kliničkog mastitisa. Kod većine krava utvrđen je jedan (68,24%) ili dva (18,63%) slučaja kliničkog mastitisa tokom laktacije. Postojao je dug period laktacije do pojave prvog slučaja kliničkog mastitisa (112,21%± 92,04 dana). Uopšteno posmatrano klinički mastitis je utvrđen tokom čitavog perioda istraž ivanja sa izvesnim varijacijama među sezonama. Za analizu zavisnosti između pojave kliničkog mastitisa i farme, pariteta krava i sezone, primenjen je jednovarijantni postupak GLM. Za analizu međuzavisnosti promenljivih u modelu korišćen je Pirsonov koeficijent korelacije. Utvrđ ena je statistički značajna razlika (p lt 0,001) između sezone i pojave kliničkog mastitisa.
