| The optimum load carrying capacity and maximum allowable work time at various slopes in the existing Sherpa mode of load carriage was determined based on 35% of maximum aerobic capacity. A convenience sample of 30 healthy agricultural who voluntarily signed an informed consent form participated in this study. The maximum loading capacity for a male is 50% of their body weight for a short duration and a minimum of 17% at 20% slope for a long duration. Considering the rate of perceived exertion in Sherpa mode of load carry, a basket holder was also conceptualized and developed. The silent features of the designed holder are (i) it can accommodate the wide range of existing baskets being used for Sherpa mode, (ii) shoulder straps were provided to transfer... |

| A capacidade dos bovinos de selecionar volumoso e concentrado em suas dietas em função de diferentes temperaturas foi estudada em 12 vacas fistuladas, durante 30 dias. Utilizou-se delineamento inteiramente casualizado com dois tratamentos: conforto (galpão, 21oC) e estresse (câmara bioclimática, 38oC), sendo a dieta composta por cana-de-açúcar acrescida de ureia e concentrado, alimentos oferecidos separadamente e à vontade. A capacidade de seleção dos animais foi identificada pela comparação da composição da dieta selecionada nos dois diferentes ambientes, assim como pelos parâmetros ruminais e digestibilidade. Foi observada redução (p < 0,05) de 22% no consumo diário de matéria seca nos animais em estresse térmico, enquanto que a relação... |

| ABSTRACT: Previous studies have evaluated the effects of different reproductive procedures on discomfort markers in sheep and cattle. Such studies may help stimulate the adoption of techniques that are more beneficial for animal welfare. However, markers that are commonly used to evaluate discomfort are highly influenced by external factors. To overcome this, several systemic markers can be evaluated to more precisely identify stress, pain, and inflammation. Such markers include cortisol, acute phase proteins, bradykinin, and substance P. We aimed to review the potential markers of stress, pain, and inflammation, and discuss how and when they are regulated after different stimuli related to reproductive procedures in cattle and sheep. Furthermore, we... |
