“…En el diseño de corrales para finalización intensiva de bovinos, un aspecto importante a considerar es el otorgar el espacio mínimo necesario que asegure el bienestar y la libre expresión de los indicadores conductuales y que conforme a las condiciones climáticas garantice el confort en un espacio físico (26). Se recomienda que el espacio vital para un bovino adulto en climas tropicales sea de 18.5 m 2 (27); en el presente estudio el espacio vital es 7.22 m 2 menor en CCS y 5.82 m 2 menor en CSS, por lo que se sugiere incrementar el espacio vital conforme aumente el peso del ganado bovino en confinamiento, debido a que el espacio reducido pone en situación de riesgo a los indicadores de bienestar de bovinos en finalización intensiva (28).…”

Objetivo: Valorar la respuesta conductual diurna de bovinos productores de carne en finalización intensiva en el trópico seco. Materiales y Métodos: En el otoño se realizó un estudio observacional prospectivo con duración de seis semanas. A las 8:00, 12:00 y 16:00 h se registraron las pautas conductuales, temperatura ambiente y humedad relativa; el índice de temperatura y humedad fue calculado. Los bovinos se alojaron en corrales provistos de sombra de polipropileno y corrales sin sombra. Resultados: A las 8:00 h todos los bovinos estuvieron sujetos a condiciones ambientales de confort térmico (p<0.01); pero a las 12:00 h los bovinos bajo sombra estuvieron en peligro térmico y a las 16:00 h en alerta térmica, y a las 12:00 y 16:00 h en los bovinos sin acceso a sombra persistió el peligro térmico (p<0.01). El acceso al comedero se inhibió a las 8:00 y 12:00 h e incrementó a las 16:00 h, pero la rumia disminuyó a las 8:00 y 16:00 y aumentó a las 12:00 h (p<0.01). Los indicadores de descanso son mayormente observados en peligro y alerta térmica (p<0.01). Los indicadores agonistas se encuentran inhibidos a las 8:00 y 12:00 h (p≤0.04). La conducta social es mayormente manifiesta a las 16:00 h (p<0.001). Conclusiones: La expresión diurna de la conducta bovina relacionada con el factor climático y la provisión de sombra, puede ser inhibida en las horas de más alta influencia calórica expresada en el índice de temperatura y humedad.

“…Inadequate feed and water supplies cause undernutrition and dehydration and the high stocking density exacerbates the problem, as not all cattle are able to gain access to feed and water. Stocking densities should relate to the animals’ needs for standing up, lying down, turning around, and movement to feed and water supplies [ 51 ]. Failure to meet these basic needs results in aggression between animals and an inability of animals that are lying down to get up [ 52 ].…”

Improvements in the welfare of animals in the intensive production industries are increasingly being demanded by the public. Scientific methods of welfare improvement have been developed and are beginning to be used on farms, including those provided by precision livestock farming. The number of welfare challenges that animals are facing in the livestock production industries is growing rapidly, and farmers are a key component in attempts to improve welfare because their livelihood is at stake. The challenges include climate change, which not only exposes animals to heat stress but also potentially reduces forage and water availability for livestock production systems. Heat-stressed animals have reduced welfare, and it is important to farmers that they convert feed to products for human consumption less efficiently, their immune system is compromised, and both the quality of the products and the animals’ reproduction are adversely affected. Livestock farmers are also facing escalating feed and fertiliser costs, both of which may jeopardise feed availability for the animals. The availability of skilled labour to work in livestock industries is increasingly limited, with rural migration to cities and the succession of older farmers uncertain. In future, high-energy and protein feeds are unlikely to be available in large quantities when required for the expanding human population. It is expected that livestock farming will increasingly be confined to marginal land offering low-quality pasture, which will favour ruminant livestock, at the expense of pigs and poultry unable to readily digest coarse fibre in plants. Farmers also face disease challenges to their animals’ welfare, as the development of antibiotic resistance in microbes has heralded an era when we can no longer rely on antibiotics to control disease or improve the feed conversion efficiency of livestock. Farmers can use medicinal plants, pro-, pre- and synbiotics and good husbandry to help maintain a high standard of health in their animals. Loss of biodiversity in livestock breeds reduces the availability of less productive genotypes that survive better on nutrient-poor diets than animals selected for high productivity. Farmers have a range of options to help address these challenges, including changing to less intensive diets, diversification from livestock farming to other enterprises, such as cereal and pseudocereal crops, silvopastoral systems and using less highly selected breeds. These options may not always produce good animal welfare, but they will help to give farm animals a better life.
