“…These intensive systems are responsible for a greater incidence of health diseases compared to extensively reared pigs, moreover, the barren environment does not allow the pigs to express many of their typical behaviours (Gade 2002). The slatted floor, wide-spread on Italian intensive pig farms, can induce mortality in slaughter pigs (Voslářová et al 2010). This trade-off makes it very difficult to evaluate overall welfare, especially because the value of each welfare problem is assessed differently by different scientists (Fraser 2003).…”

The aim of this study was to develop an innovative method for measuring the activity level of pigs in a barn in real time. An infrared-sensitive camera was placed over two pens of the piggery, images were recorded for 24 h a day for eight days during the fattening period, and the activity and occupation indices were calculated every second in real time using software. In the laboratory, the recorded images were visually labelled to score the animals' behaviour adopting the Martin and Bateson's Scan sampling method, and to find a relation with the automatically measured activity index. Pigs' behaviour was assigned in the following way, 0 -no activity, 1 -fighting or struggling, 2 -biting one another, 3 -abnormal behaviour as nuzzling or suckling one another (interacting pigs), 4 -feed assumption time. Pigs spent most of the time lying inactively (82-90% of the time), following a diurnal rhythm with peaks related to the feeding administration routine; fighting episodes occurred very rarely (0.05-0.10% of the time). Based on the analysis of the automatically measured group activity index compared to the manual labelling, a relation was found between the activity index and the behaviour types (no activity, nuzzling and feeding).The novelty presented in this study was the development of on-line tools to monitor farm animals continuously during their life, in a fully automatic way, with objective measures and criteria without imposing additional stress to the animals.

“…At the end of transport before unloading, RT, HR, RR, NLR and H50 (Table 1), Glu, COR, T3 and T4 ( Table 2) in camels that were transported with low density (Group I) were significantly lower (P<0.05) by comparison to camels that n were transported with high density (Group II). Wheras, in both groups, Hct (Table 1) and plasma levels of TP, urea, creatinine, ASAT, ALAT (Table 3), CT, TG, Ca, Pi and Mg (Table 4) were not influenced by the loading density.Stress is a nonspecific phenomenon that implicates several behavioural, physiological and emotional reactions in response to a variety of environmental stimuli (Voslářová et al, 2010). Pre-slaughter stress can start with the preparation of the animal in the farm, breeding site and market, continues with loading, transport, unloading, reception, conduction to the storage area in the slaughterhouse, and ends at the bleeding (Terlouw et al, 2005;Melesse et al, 2011;Chen et al, 2013;Miranda-de la Lama, 2013).…”

The intensity of stress depends on several external factors, such as distance and conditions of transport, climate change, the nature of the journey and the vehicle used, etc... Our research aims to study the effect of loading density on certain physiological, hematological, biochemical and hormonal parameters in camels. Sixteen male animals belonging to the municipal slaughterhouse of Casablanca (west of Morocco) were divided into two groups of 8 camels to study the effect of 2 loading densities: 1camel/2-3.6m2 (Group I) and 1camel/1.44-1.80m2 (Group II). Hct, NLR, H% and biochemical parameters were analyzed in our laboratory (LPGM) at the Ben M'Sik Faculty of Sciences in Casablanca, while the hormones were analyzed by radioimmunology at the National Center of Energy, Sciences and Nuclear Techniques of Maâmoura, Morocco. In Groups I and II, rectal temperature, heart and respiratory rates, hemolysis, neutrophil/lymphocyte ratio and plasma levels of Glu, COR, T3 and T4 showed a significant increase (P<0.05) at the end of transport just after unloading by comparison to those measured before loading and transport. All these parameters were significantly (P<0.05) higher in Group II than those observed in Group I. An increase of the loading density (1camel/1.44-1.80m2) during road transport is considered as a stressful factor that could alter the physiology of the dromedary and influence the postmortem quality of its meat. The impact of this factor on the antioxidant status of this species will be studied later.

“…This is because animals behave and respond differently to stress because of their genetic characteristics, which help them to resist and cope under heat stress (Ali et al, 2006;Allais et al, 2014). Stress is a non-specific phenomenon that represents the consequences of the behavioural, physiological and emotional status of an animal in response to a variety of environmental stimuli (Voslářová et al, 2010). These include ambient temperature, humidity, stocking density, transport and lairage duration and sometimes management on the farm and at the abattoir (Melesse et al, 2011;Chen et al, 2013;Miranda-de la Lama, 2013).…”

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. ______________________________________________________________________________________
