“…Regardless of the type of sample, aggressive dogs showed significantly lower concentrations of circulating 5-HT than nonaggressive dogs. This finding agrees with previous studies that found an association between high aggression or impulsivity and low concentrations of CSF 5-hydroxyindoleacetic acid and circulating 5-HT in primates (CSF: Melhman et al, 1994;Stanley et al, 2000;Soderstrom et al, 2001;Howell et al, 2007;platelets: Goveas et al, 2004) as well as in dogs (CSF: Reisner et al, 1996;serum: Ç akiroglu et al, 2007;Rosado et al, 2010a).…”

“…In the realm of human aggression, the measurement of blood 5-HT has offered inconclusive results, as both low (Goveas et al, 2004) and high (Golubchik et al, 2009) concentrations have been found to be linked to aggressive behavior in different populations. In canine species, 2 recent studies have reported low serum serotonin concentrations in aggressive individuals (Ç akiroglu et al, 2007;Rosado et al, 2010a).…”

“…The results obtained in this study are in accordance with the results obtained by other researchers, the serotonin value at the aggressiveness moment being lower than that reached at the reference moment (Rosado and Leon, 2010 ages of the two moments. It was established that there is a significant difference between moment 0 and moment 1, p<0.05 (p=0.02).…”

Inside the organism, serotonin is obtained through tryptophan hydroxylation and decarboxylation, and direct tryptophan decarboxylation leads to tryptamine (Figure 2) (De Research ArticleAbstract | The current study aimed to determine the serum serotonin in 10 dogs, separated in two different emotional states (calm, aggressive). According to the specialty literature, at the aggressiveness moment, the serotonin value drops. The aggressiveness manifestation in dogs is induced by several factors, among which feed occupies a special role, hypo-hyper-protean ratios influencing the behaviour. The results indicate that individuals fed with hyper-protean ratios presented lower serotonin values as compared to dogs receiving hypo-protean ratios.

“…Prior to slaughter, animals experience excessive stress owing to a sudden change of environment, which increases the secretion of enzymes (creatine kinase, creatine phosphokinase, transaminases and lactate dehydrogenate) and hormones (catecholamines and cortisol), consequently reducing the quality of meat and its products. In such instances, animal welfare is compromised, resulting in reduced meat quality and downgraded carcasses (Spores et al, 2008;Muchenje et al, 2009a;Rosado et al, 2010;Chulayo et al, 2012;. This happens against a background where numerous acts, regulations and codes of conduct are in place to safeguard animals from stress and pain.…”

Increased public concern for animal welfare in the logistics chain has led to a rise in the scrutiny of the treatment of food animals. Factors affecting the status of welfare of slaughter animals begin at the farm and occur during transportation and at the abattoir. The activities that animals pass through before slaughter are thought to have negative effects on both the animal and the product. Before or during this period, animals suffer pain, which compromises their physical, health and biochemical status, and meat quality and quantity; which leads to economic losses. Environmental impact plays a role in the behaviour, growth, development and welfare of animals, even though it is associated with the production of greenhouse gases and biodiversity. Food producers are also mindful of the challenges of feeding the ever-increasing human population. Although the issues of animal production, which range from the environment to human health, have been discussed, animal welfare-related factors that are at play in the production chain of farm animals must still be addressed. An understanding of the animal's environment, behaviour and the biochemical interactions that are at play in stressful conditions; and the implications of these for animal health and welfare are key to developing effective mitigation strategies. Therefore, the objective of this review is to highlight the literature on animal welfare, and suggest strategies that could be adopted for the improvement of meat animals, meat quality and meat products. ______________________________________________________________________________________
