1. Stress levels of mangalita, large white, and pietrain pigs reared in different housing systems in south eastern Europe
RESUMO O cortisol é um hormônio esteroide que regula uma ampla gama de processos vitais em todo o corpo, incluindo o metabolismo e a resposta imune. Ele também tem um papel muito importante em ajudar o corpo a responder ao estresse. Numerosos estudos foram realizados em todo o mundo para comparar as taxas de desenvolvimento de porcos criados em ambientes

2. TRAILER HEAT ZONES AND THEIR RELATION TO HEAT STRESS IN PIG TRANSPORT
ABSTRACT This study evaluates the dynamics of heat zones in the load and its relationship with the stress of pigs during transport. Four journeys of 170 km were monitored, recording the physiological variables of 192 animals (48 per journey), namely rectal temperature (RT), body temperature (BT), respiratory rate (RR), blood lactate concentrations and saliva

3. EFFECT OF WAVELET DE-NOISING ON THE CLASSIFICATION OF PIG BEHAVIOUR
ABSTRACT To efficiently eliminate the noise generated by the triaxial accelerometer when collecting pigs’ behavioural data, this paper adopted SNR and MSE as the indexes to evaluate the de-noising effect of pigs’ acceleration signal under various combinations of wavelet basis, decomposition layer, threshold rule and threshold function. Based on the optim

4. BEHAVIORAL RESPONSES OF PIGS FINISHED IN DEEP BEDDING AND CONVENTIONAL BED SYSTEMS
ABSTRACT The objective of this study was to characterize the thermal environment and evaluate the behavior of finishing pigs housed in deep bedding and conventional systems. The work was carried out in the Department of Animal Science of the Federal Institute of Education, Science and Technology of Southeast Minas Gerais, Rio Pomba campus. Three pens were us

5. Effect of Shenfu Injection on Isolated Empty Beating Hearts from Miniature Pigs
Abstract Objective: To investigate the effect of Shenfu (SF) injection on donor heart preservation. Methods: Twelve pigs were randomly divided into SF group (n=6) and control group (n=6). After eight hours of perfusion, the differences in hemoglobin, the expression of Bcl-2 and BAX, and changes in the myocardial ultrastructure were compared to illustrate t

6. PERFORMANCE AND WELFARE OF FINISHING PIGS SUBJECTED TO CLIMATECONTROLLED ENVIRONMENTS AND SUPPLEMENTARY LIGHTING
ABSTRACT An adequate thermal environment in pig farming facilities is essential to ensure productivity and animal welfare. The objective of this study was to evaluate the behavior and performance of finishing pigs, subjected to climate-controlled environments and supplementary lighting. Twenty-seven pigs (3/4 Duroc, 1/4 Pietrain) were kept in pens with no cl

7. USING SOUNDS PRODUCED BY PIGS TO IDENTIFY THERMONEUTRALITY ZONES FOR THERMAL ENVIRONMENT ASSESSMENT RATIOS
ABSTRACT Although dry bulb temperature (T) is the environmental variable most commonly used to classify thermal comfort in pigs, environmental assessment ratios provide more accurate information. The objective of this study was to correlate the sound pressure levels (SPL) produced by piglet vocalization with the thermal environment observed during the nurser

8. Characterization of the intestinal graft in a swine hypotensive after brain death model
Abstract Purpose: To establish a hypotensive brain death pig model and observe the effects of hypotension on small bowel donors. Methods: The hypotensive brain death model was produced using the modified intracranial water sac inflation method in ten domestic crossbred pigs. Effects of hypotensive brain death on small bowel tissue morphology were evaluated

12. Contribution of the immune system to follicle differentiation, ovulation and early corpus luteum formation
Abstract Much of what we know about the involvement of the immune system in periovulatory follicle differentiation, ovulation and subsequent formation of the corpus luteum in cattle is drawn from the findings of studies in several mammalian livestock species. By integrating published histological data from cattle, sheep and pigs and referring back to the mor
