“…This confirms earlier findings in pig industry that stockpeople can have an effect on the growth rates, by their behaviour towards the animals [17,18]. According to researchers in this area [1,2,15,16], the reason for this…”

“…Studies in the pig and poultry industries, where the major inputs to the farms were similar, have demonstrated the importance of the stockperson's contact with animals on the behaviour, physiology and productive performance of these animals [2,17,18]. In pigs reared under experimental conditions, negative interactions, like hits, slaps or electrical shocks by a prodder, lead to an increased avoidance of humans [10,14,27], and elevated chronic corticosteroid levels [15,16].…”

The relationship between farmers' attitude and behaviour towards calves, and productivity of veal units

-Although veal production is highly standardised, there still remains variability in productivity between farms, which might be due to the farmers' behaviour towards their animals, which in turn depends on their attitude towards animals. Fifty farms affiliated with the same veal company were studied. The farmers' behaviour with the calves was observed during one morning meal. The farmers were then asked to fill in questionnaires designed to measure their attitude towards calves, and to obtain information about their background (e.g. age, gender, level of education). The productivity results (daily weight gain, feed conversion, and mortality rates) were obtained from the veal company. The frequency of gentle contacts was positively correlated with the description the farmers made of their behaviour with the calves and their beliefs about the sensitivity of calves. Female farmers showed a more positive behaviour towards the calves, had more positive beliefs about the importance of contacts with calves, and made a more positive description of their own behaviour. Positive behaviour was associated with better productivity. Furthermore, bigger units had lower mortality rates. It is concluded that for veal farmers, a positive attitude towards calves, a positive behaviour towards them, and good production results are linked.veal calves / human-animal relationship / handling / behaviour / attitude Résumé -Relation entre l'attitude et le comportement des éleveurs envers les animaux, et la production de veaux de boucherie. Bien que la production de veaux de boucherie soit très standardisée, il reste une certaine variabilité dans les résultats techniques entre élevages. Cette variabilité résiduelle pourrait être due à la façon dont les éleveurs se comportent envers leurs animaux. Cette étude a pour objectifs de décrire le comportement des éleveurs avec leur veaux, d'en comprendre l'origine (en fonction de l'histoire des éleveurs et de leurs attitudes envers les veaux), et d'évaluer la relation entre la productivité des élevages et le comportement et l'attitude des éleveurs. Cinquante élevages affiliés au même intégrateur ont été étudiés. Tous utilisaient la même alimentation

“…In other studies, no effects on weight gain have been found (pigs: Pearce et al 1989, Paterson andPearce 1992;chicks: Leonard and Fairfull 1992). The same results have been detected when interpreting the effects of handling on the level of stress (pigs positive effect: Hemsworth et al 1987, Barnett et al 1994; pigs no effect: Barnett 1991, Paterson andPearce 1992). However, most of the experiments have succeeded in reducing fear reactions towards humans by handling procedures (pigs: Hemsworth et al 1987, Pearce et al 1989, Hemsworth and Barnett 1991, Paterson and Pearce 1992, Barnett et al 1994sheep: Hargreaves and Hutson 1990;silver foxes: Pedersen and Jeppesen 1990, Pedersen 1992.…”

The present study included two procedures, both aimed at improving animal welfare: early handling and changing the social conditions of the animals. Production and welfare related parameters as well as behaviour were assessed in blue fox (Alopex lagopus) cubs who were either handled or not before weaning, and housed after weaning either in pairs or in six-animal groups. The effect of the larger group size was observed in the larger number of bite scars in the female cubs housed in six-animal groups. Furthermore, the group size seemed to affect the performance of foxes most clearly in the late autumn when intra-litter aggression was observed during the feeding test. On the other hand, early handling had only short-term positive effects on the performance of the foxes but later transpired to have a negative impact on the stress profile of these animals.

“…Jago et al (1999) demonstraram que bezerros que receberam leite de uma pessoa que não interagia se aproximavam mais facilmente de uma pessoa desconhecida que os que receberam leite sem intervenção humana, este tratamento parece ser ainda mais eficiente do que contatos "positivos" (acariciar, deixar chupar os dedos) fora do horário de alimentação, além disso, em aves, a presença visual regular de um tratador reduziu as respostas de evitação das aves em relação ao homem (Jones, 1993;Barnett et al, 1994).…”

RESUMO.O Rodeio foi reconhecido como um esporte competitivo durante as primeiras décadas do vigésimo século, o objetivo deste trabalho é mostrar a relação do peão que é um atleta e sua relação com os touros de rodeio, o peão deve permanecer sobre o animal durante oito segundos segurando-se apenas com uma mão em uma corda (montarias em touros) ou sela (montarias em cavalos) de acordo com a modalidade de montaria, a outra mão deve ser colocada para cima e caso encoste-a no animal ou na cerca o atleta é desclassificado, logo após a montaria o touro para de pular. Este esporte é conhecido pela força muscular, agilidade, equilíbrio e coragem com que os competidores enfrentam os animais treinados, entretanto, grande parte dos estudos relacionados ao rodeio competitivo prioriza os aspectos psicológicos e as lesões ocorridas nesse esporte, não caracterizando o perfil de aptidão física de seus participantes, a grande diferença de força e peso entre os atletas e os animais.Palavras chaves: Bem-estar animal, arena de rodeio, montaria em touros Relation between man and bull in the rodeo arenas ABSTRACT. The Rodeo was recognized as a competitive sport during the first decades of the twentieth century, the aim of this work is to show the relationship of the pedestrian who is an athlete and his relationship with the rodeo bulls. The pawn should remain on the animal for eight seconds by holding only one hand on a rope (bull riding) or saddle (riding on horses) according to the riding mode. The other hand must be placed upwards and if it is touched on the animal or on the fence the athlete is disqualified, soon after riding the bull stops jumping. However, most of the studies related to competitive rodeo prioritize the psychological aspects and the injuries that occurred in this sport, not characterizing the profile of physical fitness. This sport is known for the muscular strength, agility, balance and courage with which competitors face trained animals. of its participants, the great difference of strength and weight between athletes and animals.Keywords: Animal welfare, rodeo sand, bull riding Relación hombre versus toro en las arenas de rodeo RESUMEN.
