“…Gregory et al (2008) reported that the average number of cuts may vary between 3.2 and 5.2 depending upon the practice, and up to 60 swipes have been found. Alam et al (2019) also reported similar prevalence. Each time the knife touches the surface of the wound the potential exists for further nociceptor activation (von Holleben et al, 2010).…”

“…These studies, evaluating neurophysiological parameters, have shown that most of the cattle seem to lose consciousness between 5 and 90 seconds after the cut, but resurgence of consciousness has been reported for more than 5 min (von Holleben et al., 2010; see Table 29). In a recent study, the reported average time to unconsciousness (assessed by corneal reflex) ranged from a minimum of 69.3 s to a maximum of 115.5 s after cutting (Alam et al., 2019). Studies have shown that the delayed onset of unconsciousness in some cattle is due to the development of false aneurism and blood supply to the brain via the vertebral artery.…”

“…Normally, the animal is cast manually using a rope tightly fastened to the legs, while pulled by tail, and the head twisted by an operator and then pushed to fall down into lateral recumbency. The neck is twisted and presented with the ventral aspect uppermost for the cut (Alam et al., 2019). Cattle restrained in this manner often struggle and attempt to right their heads indicating severe welfare consequences (Grandin, 1994).…”

The killing of cattle for human consumption (slaughtering) can take place in a slaughterhouse or on farm. The processes of slaughtering that were assessed for welfare, from the arrival of cattle until their death (including slaughtering without stunning), were grouped into three main phases: pre-stunning (including arrival, unloading from the truck, lairage, handling and moving of cattle); stunning (including restraint); and bleeding. Stunning methods were grouped into two categories: mechanical and electrical. Twelve welfare consequences that cattle may be exposed to during slaughter were identified: heat stress, cold stress, fatigue, prolonged thirst, prolonged hunger, impeded movement, restriction of movements, resting problems (inability to rest or discomfort during resting), social stress, pain, fear and distress. Welfare consequences and their relevant animal-based measures are described. In total, 40 welfare hazards that could occur during slaughter were identified and characterised, most of them related to stunning and bleeding. Staff were identified as the origin of 39 hazards, which were attributed to the lack of appropriate skill sets needed to perform tasks or to fatigue. Measures to prevent and correct hazards were identified, and structural and managerial measures were identified as those with a crucial role in prevention. Outcome tables linking hazards, welfare consequences, animal-based measures, origin of hazards, and preventive and corrective measures were developed for each process. Mitigation measures to minimise welfare consequences are proposed.

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.

IntroductionThe impact of pre-slaughter management practices on fed beef cattle welfare is a multifaceted and well researched subject matter. Factors such as transportation, handling, lairage time and several animal characteristics can directly impact the cattle’s behavior, mobility, blood lactate and cortisol levels, likelihood of injury and ultimately overall cattle welfare. Animal welfare continues to grow as a critical component of slaughter in the fed beef industry, yet a formal review of related research does not exist.MethodsA scoping review was performed in order to (1) catalog pre-slaughter management factors that impact fed beef cattle welfare at the time of slaughter, (2) identify indicators used to evaluate the impact of pre-slaughter management on fed beef cattle welfare at slaughter, and (3) gain further understanding of the relationship between pre-slaughter management factors and fed beef cattle welfare outcome indicators at slaughter. Three data bases were ultimately searched: PubMed, CAB Abstracts, and Web of Science. The concepts used in the database searches were the population of interest (i.e., fed beef cattle), the location in the supply chain, preslaughter management factors, and welfare outcomes.ResultsA total of 69 studies were included in final analysis for this review, including studies from six geographic regions around the globe. Studies involving alternative slaughter methods (e.g., religious stunning or mobile slaughter) were not included in the formal analysis of this review, but still merited an in-depth discussion within this paper. After reviewing the studies, a total of 37 pre-slaughter factors and 69 indicators of welfare were measured throughout. Pre-slaughter management factors were then categorized by: animal characteristics; environmental characteristics; handling; lairage; transportation; and water/feed. Outcomeindicators of welfare were categorized into: behaviors; health, injury and disease; physiological; and stunning and insensibility.DiscussionPre-slaughter factors relating to transportation and handling, and welfare outcomes measured by behaviors and physiology were of the most researched throughout the studies.The results of this review offer a catalogue of commonly researched factors and indicators of welfare measured during the pre-slaughter phase, as well ast he relationships between them. This review also offers further substantial evidence that a multitude of events in the pre-slaughter phase affect fed beef cattle welfare and a collection of highly applicable welfare indicators to expedite further research on the effects of pre-slaughter factors and the application of improved practices.
