“…O crescimento nesse setor trouxe consigo a inserção de novas tecnologias genéticas, nutricionais, de manejo e saúde animal (CALDARA et al, 2012). Na criação destacase a inserção do sistema confinado, que aumenta a produtividade e diminui custos, mas por outro lado potencializa a geração de dejetos.…”

RESUMO -O crescimento da suinocultura estimulou o uso de técnicas de criação animal em sistema confinado, acarretando em maior geração de dejetos com alto potencial poluidor da água, solo e do ar. O conhecimento sobre o volume de dejetos gerados é importante para fins de manejo da produção e controle ambiental e, além disso, a busca constante por melhorias na produtividade faz com que o consumo de água pelos animais também seja um fator importante a ser monitorado. Neste contexto, o presente estudo objetivou analisar o consumo de água e o volume de dejetos gerados pelos suínos nas fases creche e crescimento/terminação ao longo de 34 e 111 dias, respectivamente, analisando-se o consumo e dejetos diários e acumulados ao longo do período de estudo. Constatou-se que o consumo de água e a geração de dejetos aumentaram nas duas fases estudadas ao longo do confinamento, sendo que verificou-se associação estatisticamente significativa entre o consumo de água e o volume de dejetos gerados em ambas as fases de criação.Palavras chave: criação animal, dejetos de suínos, suinocultura.

“…Thus, seeking to replace the physiological indicators by vocalization characteristics, as the techniques to obtain the physiological responses can often cause stress to the animals. Traits such as behavior, performance and physiological parameters (both rectal and surface temperatures, and respiratory rate) as indicators of the welfare status of pigs reared on a concrete floor bedded with coffee husks have been found in the current literature [ 23 ]. Differences in cortisol levels between the pigs submitted to the pre-slaughter and stunning stress and those ones that were not exposed to this condition was reported, suggesting that cortisol level might be also used as welfare status indicator [ 24 ].…”

Simple SummaryThis research aimed to analyze the possibility of assessing piglets’ welfare using the records of their vocalization. The trial was done in a pig commercial farm, and we recorded the vocal signals from piglets in several stressful exposure situations. Data mining techniques were applied to the processed signals in order to obtain a stress classification using the recorded data. We found that, using the piglets’ vocalization, it was possible to identify the most frequent stressful conditions at the farrowing phase, namely: pain, cold and hunger.AbstractAssessing pigs’ welfare is one of the most challenging subjects in intensive pig farming. Animal vocalization analysis is a noninvasive procedure and may be used as a tool for assessing animal welfare status. The objective of this research was to identify stress conditions in piglets reared in farrowing pens through their vocalization. Vocal signals were collected from 40 animals under the following situations: normal (baseline), feeling cold, in pain, and feeling hunger. A unidirectional microphone positioned about 15 cm from the animals’ mouth was used for recording the acoustic signals. The microphone was connected to a digital recorder, where the signals were digitized at the 44,100 Hz frequency. The collected sounds were edited and analyzed. The J48 decision tree algorithm available at the Weka® data mining software was used for stress classification. It was possible to categorize diverse conditions from the piglets’ vocalization during the farrowing phase (pain, cold and hunger), with an accuracy rate of 81.12%. Results indicated that vocalization might be an effective welfare indicator, and it could be applied for assessing distress from pain, cold and hunger in farrowing piglets.

“…The differences in baseline body temperature may be explained by differences in circadian rhythms. Caldara et al [57] reported that body temperature from the neck; shoulders and leg were similar in pigs kept between compact floor, wood shavings and coffee husk. The rectal temperature was, however, higher in pigs enriched with coffee husks as compared to wood shavings and compact floor.…”

“…Therefore, more research still needs to be done looking at how the environment instigates these changes in the balance of the autonomic nervous system in pigs. Caldara et al [57] studied the effect of rearing pigs in deep bedding, coffee husks and compact floor and found that the respiratory rate did not differ between treatments. The respiratory rate was, however, above the threshold range considered normal for the species at this stage of rearing.…”

The aim of this paper is to critically analyse and synthesise existing knowledge concerning the use of environmental enrichment and its effect on behaviour, physiology and performance of pigs housed in intensive production systems. The objective is also to provide clarity as to what constitute successful enrichment and recommend on when and how enrichment should be used. Environmental enrichment is usually understood as an attempt to improve animal welfare and to lesser extent, performance. Common enrichment objects used are straw bedding, suspended rope and wood shavings, toys, rubber tubing, coloured plastic keys, table tennis balls, chains and strings. These substrates need to be chewable, deformable, destructible and ingestible. For enrichment to be successful four goals are the prerequisite. Firstly, enrichment should increase the number and range of normal behaviours (2) prevent the phenomenon of anomalous behaviours or reduce their frequency (3) increase positive use of the environment such as space and (4) increase the ability of the animals to deal with behavioural and physiological challenges. The performance, behaviour and physiology of pigs in enriched environments is similar or in some cases slightly better when compared with barren environments. In studies where there was no improvement, it should be born in mind that enriching the environment may not always be practical and yield positive results due to factors such as type of enrichment substrates, duration of provision and type of enrichment used. The review also identifies possible areas which still need further research, especially in understanding the role of enrichment, novelty, breed differences and other enrichment alternatives.
