Water buffalo (Bubalus bubalis) production in Mexico has generated particular interest in understanding the bases of the development of this species. As a result, alliances have emerged between scientific, governmental, industrial, and productive sectors and other organisms involved with this species nationally and internationally. We must recognize that thanks to specific anatomical characteristics, water buffaloes present a low incidence of complications during calving, though they are not exempt from obstetric and perinatological problems that can end in morbidity and mortality for mother and/or offspring, with losses for both branches of dual-purpose production systems: calves-milk and meat, and draft animals. This article analyzes scientific advances related to water buffalo production in Mexico, including productivity, thermoregulation, behavior, and physiology, and key subthemes like obstetric and perinatological handling, imprinting, milking, and dual-purpose production systems. It highlights features inherent to milk production and the neurophysiological and metabolic processes involved in obtaining meat and milk. Finally, it presents a brief overview of current legislation and summarizes key areas of opportunity.(AU)

Transport is considered a stressful period for livestock that can cause economic and biological losses if inadequate handling procedures exist. Several manuals and guides include recommendations for common domestic species based on scientific evidence. Still, the legislative freedom of each country means that they are not mandatory worldwide, nor do they cover all species, such as the water buffalo (Bubalus bubalis). This review aims to analyze the legal strictures currently applicable to the transport of this species. Critical aspects of the legislation that address the pre-transport, transportation, and post-transport stages are discussed, focusing on Asian and Latin American countries and the European Union. Areas of opportunity to improve the norms and laws that impact public policies, civil aspects, and water buffalo welfare in production systems are elucidated.

The present review aims to analyze the effect of extremely hot climates on the neurophysiological responses of thermal control and behavior in the river buffalo. Understanding thermal neuromodulation and its effects on the buffalo's behavior is of central importance, for this will allow us to make better decisions in terms of improving the level of welfare of buffaloes living in environments characterized by extreme heat, such as the humid tropics. The thermoregulation process involves a complex mechanism that begins with the integration of peripheral signals that are sent to the lateral parabrachial nucleus of the brainstem and then to the preoptic nucleus of the hypothalamus to generate physiological variations such as vasodilatation to dissipate heat under conditions of thermal stress, or vasoconstriction to conserve heat upon the perception of cold stimuli. The thermal biology of the river buffalo is based on several different adaptation mechanisms. The infrared thermography (IRT) technique will be of great help in this area because it permits the detection of vascular microcirculation changes in different thermal windows under adverse climatic conditions. Although buffaloes are classified as rustic animals, it is important to take into account their morpho-physiology and thermoregulation mechanisms to prevent thermal stress and the resulting poor welfare and reduced productivity. However, if appropriate thermoregulation facilities are provided (i.e., ponds, pools, potholes, or swampy areas), buffaloes can properly thermoregulate and tolerate high ambient temperatures. Therefore, they may represent a good option and an appropriate animal-based enterprise under climate change and global warming conditions.(AU)

Results on appropriate, inappropriate, and painful slaughtering methods of river buffalo (Bubalus bubalis) are discussed. Undesirable consequences of poor desensitization and/or slaughtering procedures, causing pain and suffering to animals, are also approached. These considerations are relevant as unsuitable methods can reduce consumer acceptance and commercial value of the meat obtained from animals undergoing deficient slaughtering procedures due to a lack of concern regarding their welfare. Relevant databases –Scopus, Science Direct, and PubMedwere searched for this review, including keywords such as pain, slaughter, stunning, Bubalus bubalis, and animal welfare. A detailed description of river buffalo's encephalic anatomy was compared to cattle concerning correct stunning and slaughter methods. The neurobiological processes of pain felt by animals when inadequately desensitized was also examined. Finally, recent findings on stunning methods for buffaloes were discussed, including encephalography. It was concluded that different animal species may require different stunning methods; at the same time, the optimal anatomical site also varies between species. Therefore, it is of the utmost importance to train the personnel performing these procedures (transport, stunning, slaughtering) to avoid mishandling that jeopardizes animal welfare by generating stimuli that trigger neurophysiological responses and, in turn, translate into pain during slaughter and reduced meat quality.(AU)

The objective of this review article is to discuss and analyze the most important scientific findings from studies of vascular microcirculation in the river buffalo using infrared thermography (IRT), as well as the thermal windows utilizedwith this species. The goals are to define the scope and areas of opportunity for IRT use in evaluating physiological processes and identifying potential applications in reproductive events associated with andrological traits inmales and the detection of estrus and udder health in females. IRT has allowed the development of diverse perspectives regarding the comparative physiology of events likethermogenesis, peripheral blood flow, respiratory physiology, and mechanisms that reduce body temperature. The case of the river buffalo is no exception. According to the information analyzed, the temperatures of the orbital area, muzzle, andvulva have proven efficient for evaluating thermal comfort, a particularly important aspect of this species given its limited thermoregulating capacity and constant exposure to extremetemperatures. Evaluating scrotal temperature has been revealed as an appropriate tool for evaluating semen quality, while the surface temperature of the udder is useful in assessing mammary development in female buffaloes, two aspects of great zootechnical importance. In future studies, IRT will play a fundamental role in enhancing our understanding of the river buffalo's mechanisms of vascular microcirculation, with applications in productivity and behavior.(AU)

The effect of pre-slaughter lairage stress on biogenic amines, pH, and color with the CIELab system (where three variables L*, a*, b* are estimated: L* for lightness, a* defines redness, and b* defines yellowness) in chicken breast meat was investigated. Before slaughtering, 25 broilers were selected and divided into five groups according to lairage holding time (30 min or 3 h), day/night schedule (daylight or nighttime) and control (no lairage). After slaughtering, breasts (M. Pectoralis major) were removed, stored for 9 days at 4 °C, and analyzed every 3 days. The results showed a pH decrease during nighttime holding. Also, a three-hour pre-slaughter holding (daytime or night) resulted in high biogenic amine concentration, increase in lightness (L*), and reduction in redness (a*) during storage. Cadaverine concentration showed a rapid increase from day 6 onward. The time and schedule of chicken lairage is a pre-slaughter stress factor that affects meat quality. Based on these observations, it is recommended to slaughter chickens immediately on arrival at the processing plants.


Foi avaliado o efeito do estresse produzido pelo tempo de espera pré-abate sobre a produção de aminas biogênicas, pH e cor pelo sistema CIELab (onde três variáveis L*, a*, b* foram determinadas: L* indica a luminosidade, a* indica o vermelho e b* determina o amarelo) na carne de peito de frango. Antes do abate 25 frangos de carne foram selecionados e divididos em cinco grupos conforme o tempo de espera pré-abate (30 min ou 3 h), programação dia/noite (diurno ou noturno) e controle (sem tempo de espera). Após abate, os peitos (M. Pectoralis major) foram separados, estocados por 9 dias a 4°C, e analisados cada 3 dias. Os resultados evidenciaram uma redução do pH nas aves que aguardaram o abate na noite. Além disso durante a estocagem incrementou-se os valores de aminas biogênicas e da luminosidade (L*) e houve redução dos teores de vermelhos (a*) no tempo de espera de três horas (diurno ou noturno). As concentrações da cadaverina incrementaram-se a partir do dia 6 de estocagem. O tempo e horário de espera em frangos de carne pode é um fator de estresse pré-abate que afeta a qualidade da carne. Contudo, é recomendável realizar o abate dos frangos imediatamente após de sua chegada ao centro de abate.
