Although it is still most common to rear dairy calves separately from adult cattle, the interest in prolonged contact between and lactating cows during early life increasing. Previous research has documented positive effects of cow-calf (CCC) on for example calf growth udder health suckled cows, but also negative such as increased separation distress reduced weight gains after weaning. The aim this study was use information European farms with identify innovative solutions challenges CCC...
On-farm mortality (unassisted death and euthanasia) is the unwanted loss of animals, it comes with negative economic consequences. rates reflect a herd's animal welfare status. The objective this historical longitudinal single cohort study was to identify associations between herd characteristics, housing conditions management routines within-herd calf cow in participating Estonian dairy herds. All farmers enrolled voluntary production recording system size 20 or greater cow-years 2015-2017...
Longevity is an important trait for increasing the profitability of dairy production. Long cow longevity also essential to reduce environmental impact milk production, and maintain positive consumer attitude. Genetic selection increased has been effective, but phenotypic trend in Swedish cows not improved. The objective this study was identify herd characteristics management routines that are associated with average a herd. To obtain information, questionnaire developed sent out 661...
Dairy cow mortality is an important animal welfare issue that also causes financial losses. The objective of this study was to identify farm characteristics and herd management practices associated with high on-farm in Swedish dairy herds. A postal questionnaire sent farmers had either or low rates for 3 consecutive years. consisted five sections: 'About the farm', 'Milking housing', 'Feeding', 'Routines' 'Lame sick cows'. total 145 questionnaires were returned (response rate=33%). Ten 77...
The number of born piglets per litter has increased in Swedish pig industry, and farmers are struggling to improve piglet survival. A common practice is make litters more equally sized by moving from large smaller sure that all get an own teat suckle. Litter equalization not always enough, as many sows have and/or damaged teats, which results insufficient available teats. One way solve this problem use nurse sows. sow raises, weans, her before receiving a foster litter. objectives study were...
Abstract Increased on-farm cow mortality (ie unassisted death and euthanasia) has been demonstrated in Swedish dairy herds during the last decade. Identifying risk factors associated with type of is needed for future work reducing rates. The objectives this case-control study were to quantify relative proportion dead cows among that die on-farm, identify (as opposed euthanasia). In Sweden, cadavers animal waste products are being processed into biofuel at destruction plants. Two plants...
The aim of this study was to screen for selected parasites and antibody levels against vectorborne pathogens in owned dogs Lilongwe, Malawi. population consisted 100 dogs; 80 participating vaccination-spaying campaigns 20 visiting a veterinary clinic as paying clients. All went through general physical examination including visual signs ectoparasites. A total blood samples were analysed using commercial snap tests 40 faecal by egg flotation saturated sodium chloride. sampled had...
Human and bovine respiratory syncytial virus (HRSV BRSV) are closely genetically related cause disease in their respective host. Whereas HRSV vaccines still under development, a multitude of BRSV used to reduce clinical signs. To enable the design vaccination protocols entirely stop circulation, we aimed investigate duration, character efficacy immune responses induced by natural infections. The systemic humoral immunity was monitored every two months during years 33 dairy cattle different...

Abstract We estimate the relationship between farm animal welfare (FAW) efforts taken by beef farmers and economic performance of farms using accounting data from Swedish Farm Economic Survey matched with survey on management practices. To this end, we perform a two-step analysis. First, an item response theory (IRT) model estimates latent FAW effort farms. likely depends host complementary FAW-improving strategies, IRT combines considered strategies into unidimensional scale. take to...
Introduction While early separation of dairy calves after birth has been debated from an ethical and animal welfare lens, the economic evidence surrounding alternative cow-calf contact (CCC) systems is scarce. Methods To address this knowledge gap, we assessed consequences CCC using data Agriwise database as well parameters published literature in a stochastic partial budget model. The implementation very diverse between farms, so our study therefore selected limited number to assess....
Transboundary pathogens pose a threat to livelihood security in countries such as Zambia and Tanzania. This study aimed investigate the seroprevalence of peste des petits ruminants virus (PPRV), foot mouth disease (FMDV), sheep goat pox (SGPV), Rift Valley fever (RVFV) Brucella spp. goats along Tanzania-Zambia border. Another aim was assess association between certain predictor variables seroprevalence, focusing on trade proximity an international border, town highway. During...
The societal demand for good farm animal welfare (FAW) has increased over time. Yet, very little is known about the economic consequences of improvements in FAW cow–calf operations. This study investigates on-farm improved measures It uses a stochastic partial budgeting approach to examine relationship between contribution margins and terms space allowance typical Swedish cow-calf operation, as compared current practices. In practice, cow should be given at least 5 m2 calf 2.2 m2. We found...
undergo post-mortem examination (Swedish Veterinary Agency, 2022).This means that the reported cause of death is often based on farmers own assessment, which can be misleading or even incorrect (McConnel et al., 2009;Thomsen 2012;Alvåsen 2014).The limited numbers examinations Swedish cattle might due to logistical barriers, e.g., transport cadaver a site within reasonable time.In Sweden, cost at
Loss of animals is a considerable waste resources in the meat supply chain, where quantitative data are scarce but critical for guiding improvements. In this study, we used material flow analysis to track amount beef diverted away from food chain at farm level. The losses (absolute and as proportion yearly initial production) were estimated on assisted unassisted deaths cattle Swedish farms obtained central register bovine 2002–2021 combined with official statistics slaughter weight. fallen...
