This study on the removal of microplastics during different wastewater treatment unit processes was carried out at Viikinmäki plant (WWTP). The amount in influent high, but it decreased significantly process. major part fibres were removed already primary sedimentation whereas synthetic particles settled mostly secondary sedimentation. Biological filtration further improved removal. A proportion microplastic load also passed and found effluent, entering receiving water body. After process,...
The nitrous oxide emissions of the Viikinmäki wastewater treatment plant were measured in a 12 month online monitoring campaign. measurements, which conducted with continuous gas analyzer, covered all unit operations advanced wastewater-treatment process. relation between and certain process parameters, such as temperature, influent biological oxygen demand, ammonium nitrogen load, was investigated by applying data obtained from process-control system at 1 min intervals. Although seasonal...
Genetic selection and better control of the environment pigs have resulted in increased production levels concerning both reproduction growth. Such high performances imply physiological demands that may deteriorate health welfare. The aims this paper are to review challenges facing, identify possible consequences on welfare, propose ways detecting correcting problems whenever possible. At weaning, piglets submitted abrupt changes food supply, housing social environment. Behavioural efficient...
Most of us have experienced deterioration mood while ill. In humans, immune activation is associated with lethargy and social withdrawal, irritability aggression; changes in motivation could, theory, lead to less functional interactions. This might also be the case for animals housed close confinement. Tail biting pigs an example damaging behavior, sickness thought a risk factor tail outbreaks. One possible mechanism whereby may influence behavior through cytokines. To identify mediators...
The prevalence of lameness among 646 sows and gilts in 21 selected herds was determined; 8·8 per cent the animals were lame most common clinical diagnoses osteochondrosis, infected skin lesions claw lesions. had higher serum concentrations haptoglobin C‐reactive protein than sound animals. Animals housed on slatted floors twice odds being 3·7 times severely solid floors. Yorkshire pigs 2·7 Landrace or crossbred Higher parity use roughage decreased not becoming pregnant; however, a risk...
Health in relation to tail-biting behaviour was investigated on a problem farm. Quartets (n = 16) of age- and gender-matched fattening pigs including tail biter (TB, n 16), victim (V, control the same pen (Ctb, 10) where no biting observed (Cno, 14) were chosen by direct behavioural observation. Haematological clinicochemical analyses, autopsy histological examination 16 different tissues carried out. Tail lesion severity evaluated both macroscopically, basis inspection, histologically,...
Tail biting is a common welfare problem in pig production and addition to being sign of underlying problems, tail reduces itself. The aim this study was evaluate the effects on different pre post mortem indicators stress slaughter pigs carcass meat characteristics. A total 12 bitten (TB) 13 control (C) from farm with long-term were selected for salivary cortisol analyses before after transport slaughterhouse. After stunning, samples taken analysis serum cortisol, blood lactate, intestinal...
An Activated Sludge Model #3 (ASM3) based, pseudomechanistic model describing nitrous oxide (N2O) production was created in this study to provide more insight into the dynamics of N2O production, consumption, and emissions at a full-scale wastewater treatment plant (WWTP). studied WWTP are monitored throughout with Fourier transform infrared analyzer, while developed encountered biological reactors via both ammonia oxidizing bacteria (AOB) nitrification heterotrophic denitrifiers....
Tail biting is a common and serious welfare problem in pig production, causing large economical losses. docking performed routinely most EU countries to reduce the tail risk. However, painful, does not prevent totally. The risk factors behind are multifactorial analyses based on studies using biological or epidemiological approaches. There very little information available how producers deal with on-farm. also no attitude of towards systems long-tailed pigs. We aimed study farmers rate...
Tail biting lesions are a potential measure of on-farm animal welfare, as large range stressors increase the risk for tail outbreaks. Further, is major challenge, due to decrease welfare and health, well production efficiency carcass quality. The aim this study was suggest scoring system use at slaughterhouses processing undocked pigs. definition an intact enough tail. To validate suggested we assessed tails before after scalding compared results pathological examinations. In total, 14 433...
