“…Therefore, the blood concentration of lactate relies on its production and degradation in the liver, kidneys, and skeletal muscles (Henry, 2008). The measurement of plasma lactate has been widely used for the evaluation of stress, meat quality and control of animal welfare in pigs (Ludtke et al, 2010;Baptista et al, 2011).…”

The objective of this study was to evaluate the supplementation of guanidinoacetic acid (GAA) and L-arginine (L-Arg) as creatine precursors to vegetable diets on the carcass yield and meat quality of broilers subjected to two days of heat stress before slaughter. A total of 1260 broiler chicks were distributed according to a completely randomized design into four treatments with nine replicates of 35 birds each. The treatments consisted of: T1 -vegetable diet based on corn and soybean meal (control diet); T2 -control diet with the inclusion of meat meal (3%); T3 -control diet supplemented with GAA (0.08%); and T4 -control diet supplemented with L-Arg (0.8%). The birds were submitted to heat stress for two days before slaughter (from 42 to 44 days of age). The birds fed the diets supplemented with GAA or L-Arg presented heavier carcasses (p<0.0035), higher breast yield (p=0.0685), and lower of abdominal fat deposition (p=0.0508) than those fed the control diet and the control diet with meat meal. The cooking loss of the breast fillets of broilers fed the control diet supplemented with meat meal, GAA or L-Arg was lower (p<0.0068) compared with those fed the control diet. Thawing and pressure-driven breast fillet weight losses, and pH, luminosity, redness (a*value), and yellowness (b* value) values were not influenced by the treatments. When GAA is less expensive than commercially-available Arg, the dietary supplementation of GAA is more advantageous, based on the meat yield improvements observed in the present study.

“…Thus, resting pens should be a peaceful environment, minimizing animal stress during pre-slaughter handling (DALLA COSTA et al, 2009). According to BAPTISTA et al (2011), swine metabolic mechanisms maintain homeothermy when animals are submitted to high temperatures, so the ambient temperature influences both the surface and body temperatures, which may act as the animal physiological response to inadequate and adaptive environmental conditions (NASCIMENTO et al, 2011). Therefore, the adequate resting time associated with pen conditions at slaughterhouses (easy access to water, sprinkler system, and fans) contribute to thermal stress reduction and animal recovery, thus better carcass temperature .…”

Integrated multivariate analysis to evaluate effects of pre-slaughter handling on pork quality

et al. 2014

ABSTRACT:The aim of this study was to investigate the effect of pre-slaughter handling on the occurrence of PSE (Pale, Soft, and Exudative) meat in swine slaughtered at a commercial slaughterhouse located in the metropolitan region of Dourados, Mato Grosso do Sul, Brazil. Based on the database (n=1,832 carcasses), it was possible to apply the integrated multivariate analysis for the purpose of identifying, among the selected variables, those of greatest relevance to this study. Results of the Principal Component Analysis showed that the first five components explained 89.28% of total variance. In the Factor Analysis, the first factor represented the thermal stress and fatiguing conditions for swine during pre-slaughter handling. In general, this study indicated the importance of the pre-slaughter handling stages, evidencing those of greatest stress and threat to animal welfare and pork quality, which are transport time, resting period, lairage time before unloading, unloading time, and ambience.

“…A dosagem do hormônio cortisol é utilizada para monitorar o estresse, assim como as Proteí-nas de Fase Aguda (PFA), que além do estresse, indicam processos inflamatórios e infecciosos no animal (GUTIERREZ et al, 2009;BAPTISTA;BERTANI;BARBOSA, 2011). Na metade do século XX surgiram os primeiros estudos sobre a composição de proteínas na saliva dos suínos: presença de amilase em suínos jovens (HUDMAN et al, 1957), detecção das PFA (GUTIERREZ et al, 2009;BAP-TISTA;BERTANI;BARBOSA, 2011) Mestecky et al (2005) afirmam que as concentrações de imunoglobulinas no TCO são mais elevadas do que na saliva. Ferri (1998) argumenta em uma revisão sobre a utilização do TMO como amostra clínica no diagnóstico laboratorial do HIV que a alta viscosidade da saliva prejudica a sua coleta e que os anticorpos (anti-HIV) presentes na saliva são principalmente IgAs, enquanto os encontrados no TMO são principalmente os IgGs, classe principal de anticorpos anti-HIV.…”

BARBOSA JÚNIOR, S. A.; BAPTISTA, R. I. A. de A.; BARBOSA, C. N. Fisiologia comparada do fluído oral e suas principais aplicações clínicas. Arq. Ciênc. Vet. Zool. UNIPAR, Umuarama, v. 18, n. 4, p. 259-268, out./dez. 2015. RESUMO:O fluido oral é um líquido incolor e viscoso que resulta da combinação entre a saliva e os transudatos da cavidade oral, transudato da mucosa oral e fluido crevicular gengival. A saliva é secretada pelas glândulas salivares, enquanto o transudatos da cavidade oral tem origem nos capilares da mucosa e nos tecidos gengivais. O uso do fluido oral é assegurando por uma ampla base de investigações científicas na medicina humana e veterinária. Vários patógenos podem ser avaliados pela reatividade de anticorpos e ou identificação de antígenos. Além disso, o procedimento de coleta é simples, não invasivo e garante uma amostragem sistemática nos diagnósticos clínicos e em pesquisas. Por conseguinte, as informações relacionadas à secreção e composição, bem como os mecanismos de transporte dos componentes do fluido oral são de grande valor. Objetivou-se com este trabalho realizar uma revisão de literatura sobre o fluido oral, enfatizando o processo de secreção, composição, mecanismos de transporte de substâncias, bem como suas aplicações clínicas e principais limitações nos seres humanos e nos animais domésticos. PALAVRAS-CHAVE: Bem estar. Diagnóstico. Saliva. COMPARATIVE PHYSIOLOGY OF FLUID ORAL AND MAIN CLINICAL APPLICATIONS ABSTRACT:The oral fluid is a colorless and viscous liquid that results from the combination of saliva and transudates of oral cavity, oral mucosal transudate and gingival crevicular fluid. Saliva is secreted from the salivary glands, while the transudates of oral cavity as its origin in capillary mucosa and gingival tissues. The use of oral fluid is thereby ensuring a broad base of scientific research in human and veterinary medicine. Several pathogens can be assessed by reactivity or identification of antibodies and antigens. Furthermore, the collection procedure is simple, noninvasive and provides a systematic sampling in clinical diagnostics and in research. Therefore, the information related to the secretion and composition as well as the transport mechanisms of the oral fluid components are of great value. The aim of this work is make a critical review of the oral fluid, emphasizing the process of secretion and composition, transport mechanisms of the substances present in the plasma to the oral cavity and its clinical applications and major limitations in humans and domestic animals.
