“…The observed increase in plasma LDH activities with age may parallel the changes observed in plasma CK and similarly reflect an increase in muscle damage or spontaneous myopathy during reductions in ovarian steroid secretion. Plasma LDH activity is increased in birds with chemically induced muscle necrosis (Lumeij et al, 1988) and similar patterns of change in plasma LDH and CK were observed in response to halothane challenge in broiler chickens . In treatment groups in which increasing rates of mortality were found (Hocking et al, 2002) the elevated plasma LDH activity may also reflect the onset of myocardial dysfunction or pathology of other tissues including the liver.…”

1. Broiler breeder females were reared on one of three growth curves (ad libitum, conventional or modified restriction) and given rations containing a high or low concentration of crude protein. After the peak rate of lay they were fed ad libitum or a decreasing quantity of food in response to declining egg production. The welfare of the birds was assessed by determining the changes in indices of welfare at 36, 48 and 60 weeks of age. 2. Body weight increased rapidly in restricted birds fed ad libitum post-peak and water intake declined. 3. Post-peak food restriction was associated with a decrease in resting and increased drinking and spot-pecking activities. Birds that were food restricted during rearing spent more time foraging and spot-pecking at 36 and 48 but not 60 weeks of age. 4. Immune function increased with age but was not affected by the experimental treatments. The heterophil-lymphocyte ratio in birds fed ad libitum during rearing was numerically lower at 36 and higher at 48 and 60 weeks of age compared with restricted birds. 5. There was no effect of treatment on plasma corticosterone concentration. Creatine kinase activity was high at 60 weeks in treatments that were characterised by poor reproductive status and the activities of other enzymes reflected differences in reproductive status and mortality. 6. There was no long-term welfare or production advantage from feeding low protein rations or more generous feeding during the rearing period compared with conventional food restriction programmes.

“…Overt muscle damage in birds is associated with an increase in the plasma activity of the intracellular muscle enzyme creatine kinase (CK) (Siller et al, 1978;Lumeij et al, 1988). In broiler chickens CK is released into the circulation following changes in the permeability of the sarcolemma in response to various pathologies and exposure to environmental stressors (Mitchell et al, 1992;Mitchell and Sandercock, 1995).…”

1. Plasma creatine kinase activity was determined at 4, 8, 12, 16, 20, 24, 28, 38 and 48 weeks of age in male and female traditional turkeys fed ad libitum, in male and female turkeys of a sire-line fed ad libitum or restricted to 0.5 during rearing and subsequently to 0.8 of sex-specific ad libitum-fed body weight, and in sire-line males fed ad libitum to 18 weeks and 0.8 of ad libitum body weight thereafter. 2. Plasma creatine kinase activity was low in traditional turkeys and increased rapidly after 12 weeks of age in males and females of the sire-line of turkeys. 3. Food restriction decreased the activity of plasma creatine kinase. 4. There was no difference in plasma creatine kinase activity between the sexes during rearing. After the onset of lay, the activity in plasma from females decreased at 38 weeks of age and rose dramatically in restricted females at 48 weeks when the birds had ceased laying. 5. The changes in plasma creatine kinase activity in females were associated with concomitant changes in ovarian activity as reflected in altered plasma triglyceride concentrations.

“…Li et al (2008) stated that LDH was not a good measure of stress under transport conditions as compared with significant CK changes in pigs. In response to stress, CK from muscles is released into the blood (Lumeij et al 1988). Our experimental stressor was thought to be an adequate stimulus for increasing measured blood enzymes, except for amylase.…”

The objective of this study was to examine the effect of pre-slaughter environment on physiology and meat quality in New Zealand rabbits. Pre-slaughter environment consisted of combined effects of social and non-social factors. For the experiment, 18 male New Zealand rabbits (Oryctolagus cuniculus), 3 months of age, were used. Some biochemical and meat quality parameters of the animals were measured, and the results were compared with the control group. The pre-slaughter environment significantly influenced some biochemical and meat quality parameters (P < 0.01 and P < 0.05, respectively). It is concluded that pre-slaughter environment negatively affected the welfare status and decreased the meat quality in New Zealand rabbits.
