Induced Stress and Tactile Stimulation Applied to Primiparous does and their Consequences on Maternal Behavior, Human-Animal Relationships, and Future Offspring's Sexual Disorders.

The aim of this study was to investigate whether tactile stimulation in rabbits during the gestation phase improve the maternal behavior and human-animal relationships as well as the effects on reproductive behavior of male kits when reached maturity compared to induced stress. A total of 33 primiparous New Zealand does were selected after pregnancy confirmation and allocated in a randomized complete block design. The treatments applied were as follows: (C) animals not stimulated during the experimental period; (TS) animals that received tactile stimulation; and (SS) does which were immobilized. The nest building behavior as well as the weight, sexual behavior, mortality, and semen analysis of the offspring was recorded. In addition, the novel object, flight distance, social isolation, and human-approach tests were conducted. Under the conditions of the present trial, TS animals showed more trust in the unfamiliar observer when compared to the other two treatments. The treatments applied to the females (TS and SS) were sufficient to confirm that the control group presented better values for the number of stillbirths and the proportion of deaths in the first week. Finally, the handling of does reduce the males' ejaculation and sperm presence but not inhibited sexual behavior or impaired semen quality. It is possible to conclude that TS did not impair does welfare or maternal behavior and it improved the human-animal relationship, however there was a negative impact on the litter. More studies that directly assess impact on the future reproductive capacity of the offspring are necessary.

Animal-Assisted Activity for Children with Autism Spectrum Disorder: Parents' and Therapists' Perception.

Autism spectrum disorder (ASD), characterized by communication and social interaction difficulties, might be positively influenced by animal-assisted activity (AAA). The aim of this study was to investigate the parents' and therapists' perception to behavior in children with ASD after they underwent AAA. The study was performed in a specialized therapeutic center in Curitiba, South of Brazil. A total of 15 children (14 boys and 1 girl), aged 5.6 ± 1.6 years, diagnosed with ASD, underwent at least 10 weekly 30-min AAA sessions. Three trained dogs were used in total, and there were two dogs in each session. Children were free to interact with dogs and among themselves, in groups of 11.2 ± 2.2 children per session, in the presence of therapists, the researcher, and a veterinarian observing the dogs and ensuring safety. The parents and therapists completed two questionnaires on their perception of the children's behavior before and after AAA. A total of 18 visits were necessary to complete the 10 sessions for each of the 15 children. According to the therapists' perception, AAA increased positive gestures and facial expression in children (p = 0.010) and improved peer interaction. Even though there was a 50% reduction in the parents' feedback at the end of the study, according to their perception there was a reduction in self-aggression and repetitive stereotyped movements, as well as an improvement in speech communication and creativity. This study demonstrated the positive effects of the AAA on the social behavior of children with ASD.
