“…The exposure to a daily 3–4 h noise regime of 65 dB for 18, 28, 40 and 50 days caused a general increase in biochemical parameters such as urea, uric acid, creatinine, cholesterol and triglycerides, while glucose level decreased significantly in domestic male rabbits weighting 1,000–1,200 g (Elwasife et al., 2015). The authors concluded that noise exposure may also enhance gluconeogenesis and glucose mobilisation to the blood.…”

This opinion, produced upon a request from the European Commission, focuses on transport of domestic birds and rabbits in containers (e.g. any crate, box, receptacle or other rigid structure used for the transport of animals, but not the means of transport itself). It describes and assesses current transport practices in the EU, based on data from literature, Member States and expert opinion. The species and categories of domestic birds assessed were mainly chickens for meat (broilers), end-of-lay hens and dayold chicks. They included to a lesser extent pullets, turkeys, ducks, geese, quails and game birds, due to limited scientific evidence. The opinion focuses on road transport to slaughterhouses or to production sites. For day-old chicks, air transport is also addressed. The relevant stages of transport considered are preparation, loading, journey, arrival and uncrating. Welfare consequences associated with current transport practices were identified for each stage. For loading and uncrating, the highly relevant welfare consequences identified are handling stress, injuries, restriction of movement and sensory overstimulation. For the journey and arrival, injuries, restriction of movement, sensory overstimulation, motion stress, heat stress, cold stress, prolonged hunger and prolonged thirst are identified as highly relevant. For each welfare consequence, animal-based measures (ABMs) and hazards were identified and assessed, and both preventive and corrective or mitigative measures proposed. Recommendations on quantitative criteria to prevent or mitigate welfare consequences are provided for microclimatic conditions, space allowances and journey times for all categories of animals, where scientific evidence and expert opinion support such outcomes.

“…Total protein could be designated as a long-term stress indicator in rabbits, as a study of the effect of noise on rabbits showed significantly lower total protein values after 50 days of daily exposure (Elwasife et al 2015) and another one reported that a higher concentration of rabbits in a cage also resulted in a reduction in protein values (Kalaba 2012).

“…The level of glycaemia is considered a stress indicator in a number of other cases because many factors lead to the change of the glucose concentration in rabbits (Washington and Van Hoosier 2012), e.g. chronic noise exposure can cause a reduction (Elwasife et al 2015) but heat stress (Składanowska-Baryza et al 2018), higher concentration of rabbits in the cage (Kalaba 2012) or transport to slaughter (Składanowska-Baryza et al 2018) can cause its elevation. Transport and manipulation in the laboratory can increase the glucose concentration (and other variables) in laboratory rats (Castelhano-Carlos and Baumans 2009).…”

This study was intended as a contribution to the argument about possible suffering of animals used for demonstrative purposes during teaching at universities. Pharmacology lectures at the University of Veterinary and Pharmaceutical Sciences Brno, Czech Republic were selected for this experiment. The study focused on stress assessment using haematological and biochemical indices. Blood samples were drawn from 20 rabbits (Oryctolagus cuniculus f. domesticus L.) 10 days after arrival at the institute (before the first practical lesson), and then in the 7th and 12th weeks of the semester with practical lessons. The haematological and biochemical indices were compared between the experimental group (n = 10) used for practical demonstrations and the control group (n = 10) which was kept in its hutch. Practical lessons included manipulation with rabbits, health examination, topical or total application and observation of the drugs’ effects. All the acts were carried out by students. Significant changes were detected in some of haematological (erythrocytes, haemoglobin, haematocrit) and biochemical (glucose, total protein, enzymes aspartate aminotransferase and lactate dehydrogenase) variables compared to the control group. The values obtained from the last blood sampling indicate a possible habituation process in the experimental group between the 8th and 12th week. The results were compared between the experimental and control group and also with the results of other studies with different stressors. In conclusion, the stress the rabbits used for teaching purposes at universities are exposed to, is tolerable.

“…This induction of white blood cells is a positive response for survival due to cell mediated immune response of animals Leukocytosis was manifested by lymphocytosis, which were the main features of the differential leukocytic count. iT found that the noise exposure decreased the concentrations of serum glucose, total protein, globulin, and albumin [46,47].…”

This study have shown the comparison between the effect exposure to the noise and electromagnetic waves radiation on rabbit. Environmental noise and electromagnetic fields are a known stressful factor that induces alterations of various physiological responses in the exposed individuals. The electromagnetic field applied was generated by using an antenna installed at the laboratory of Islamic University of Gaza. The mobile system used in Gaza is GSM with frequency equals 900 MHz. The antenna place at 20 cm away from the animals such that the whole body exposed to the electromagnetic field on the days of the test the rabbits were brought to the laboratory. The experiment was conducted at Gaza strip laboratory. Twenty two adult male rabbit were used throughout the study. Rabbits were randomly divided into three groups. The first group consists of ten rabbits (w1000-1200gm) served as the control group. During the course of the study the animals were housed in pairs in the animal house with food and water and kept under standard environmental conditions for light (12: 12 h light: dark cycle) temperature (27°C). The second group was subjected to the noise levels (60-70 dB) for 18 days. The animals were exposed to noise product from generator with 1KW and dimension of 1200 mmx1100 mmx1300 mm. They exposure for 3-4 hour in each day. The third one of animals were exposed to split dose of electromagnetic field with constant power in the range from (1.4-4.7) mw/cm 2 and electric field with the range (60-130) V/m. The treated animals were subjected to electromagnetic field for eight hours then rest eight hours without exposure. The process of exposure and rest for the same time interval were repeated for two weeks. Animals from both control and experimental groups were decapitated at the end of the experiment. Blood samples were collected in 10 ml plain tubes for serum preparation. The effect of electromagnetic exposure is greater than noise one in urea, uric acid, creatinine, Alpha., AST, ALT and PLT. Exposure to noise caused increase triglycerides, white blood cell counts, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration. It was found to be directly related to the duration of exposure, the intensity and the characteristics of the noise with loud intermittent noise and longer duration of exposure producing more analgesia.
