“…Likewise, environmental enrichment with scented elements was found to promote behavioral changes [1]. The rearing environment enriched with objects is likely to instigate pig curiosity [31].…”

“…However, this type of system has been questioned due to the volume and difficulties in properly managing waste, which entails serious environmental pollution issues, and due to reduced animal well-being [1]. Abnormal behaviors are commonly observed in animals reared in confinement since the inability of exercising the species natural behaviors significantly impacts their well-being.…”

“…This strategy stimulates the behaviors typical of the species, thus lowering stress and making the captive environment more complex and diverse by meeting their ethological needs [1]. According to Campos [3], environmental enrichment is a way of providing better living conditions to the animals.…”

“…According to Campos [3], environmental enrichment is a way of providing better living conditions to the animals. Pigs reared in enriched environments typically show behavioral evidence of better well-being compared to those in confinement [1] and, when the strategies are well planned and applied, they may significantly reduce the frequency of abnormal behaviors [4]. …”

Three trials were carried out in a completely randomized design aiming to assess the behavior of pigs in growth phase in enriched environments. Trial 1 evaluated the effects of frequency of availability of environmental enrichment. The animals were assigned to four treatments: 1) control with no enrichment object; 2) objects provided for six consecutive days uninterruptedly; 3) objects provided on alternate days, and 4) objects provided for six consecutive days taken away by the end of the afternoon and replaced at dawn. Trial 2 assessed the effects of scent on animals’ acceptance and maintenance of interest in objects. Animals were assigned to four treatments: 1) unscented object; 2) object with banana scent; 3) object with rum scent; 4) object with scents alternated every other day. Trial 3 aimed to assess the influence of environmental enrichment based on providing rewards at different difficulty levels. Animals were assigned to three treatments: 1) object with no reward; 2) object with a reward at an easy level; 3) object with a reward at a difficult level. Each trial had six days of behavioral observations every ten minutes for eight hours each day using images from video cameras. Enrichment objects stimulated the animals’ natural behavior of nuzzling and exploring the environment. The way the objects were available did not impact the success of their use. Offering enrichment on alternate days or removing the objects by the end of the day was not an effective strategy to extend the animals’ interest. The olfactory stimulus in environmental enrichment objects had no positive effect on extending the animals’ interest on them, nor did alternating the aromas. The tactile stimulus was a key factor for object attractiveness. Providing environmental enrichment objects with rewards stimulated the exploratory behavior of pigs. The level of difficulty to obtain the reward may discourage the animals.

“…Neste contexto, o enriquecimento ambiental surge como uma alternativa para melhorar a qualidade do ambiente de animais confinados, a partir de estímulos diversos, que sejam capazes de oferecer bem-estar psíquico e fisiológico, com a estimulação de comportamentos típicos dos animais (Vasconcelos et al, 2015). O enriquecimento ambiental melhora o bem-estar, permitindo a apresentação de comportamentos típicos da espécie, atuando no desenvolvimento físico e psicológico dos animais (Foppa et al, 2014), e atualmente é classificado de acordo com a atividade que exerce dentro do confinamento, as quais são classificadas como social, ocupacional, físico, sensorial e nutricional (Bloomsmith et al, 1991).…”

Interesse comportamental de machos suínos por diferentes tipos de enriquecimentos ambientais

et al. 2018

O objetivo deste estudo foi avaliar o comportamento de machos suínos a partir da inserção de correntes e pneus como enriquecimento ambiental em confinamento. O estudo foi realizado na Universidade de São Paulo, em Pirassununga – SP, Brasil. Foram utilizados seis machos híbridos, de 12 a 30 meses. Foram inseridos correntes e pneus, individualmente. O comportamento e o tempo de interesse pelo enriquecimento foi obtido observando o momento em que o animal procurava pelo objeto inserido, com observações diretas, sem intervalos, de manhã e à tarde. Foram aferidas as temperaturas superficiais do corpo dos animais e ambientais, com obtenção da frequência respiratória no início e no final das observações. Foram realizadas colheitas de cortisol salivar, por meio de corda de algodão individualmente. Foi realizada análise de tipo de enriquecimento e idade por análise de qui-quadrado, correlação de Pearson entre o comportamento e temperatura de superfície corporal e teste-t para frequência respiratória e temperatura do ambiente. A idade dos cachaços não teve influência no comportamento de interesse (P>0,05). No total, 79,86% dos machos não apresentaram interesse pela corrente, no entanto, 61,11% dos machos apresentaram interesse pelo pneu. No ambiente controle, 91,67% dos animais permaneceram em ócio. A frequência respiratória encontrada foi maior a tarde (P<0,05). As dosagens séricas de cortisol, foram de 0,5 a 3,1 ng/mL, 0,5 a 0,9 ng/mL, 0,5 a 1,2 ng/mL e de 0,9 a 1,2 ng/mL. Conclui-se que o enriquecimento ambiental nas instalações de suínos machos constitui-se como importante ferramenta, sendo o pneu o melhor método de entretenimento quando comparado ao uso de correntes.
