A study was conducted to compare the effect of halal slaughter without stunning and gas stun killing followed by bleeding on residual blood content and storage stability of rabbit meat. Eighty male New Zealand white rabbits were divided into two groups of 40 animals each and subjected to either halal slaughter without stunning (HS) or gas stun-kill (GK). The volume of blood lost during exsanguination was measured. Residual blood was further quantified by determination of haemoglobin content in Longissimus lumborum (LL) muscle. Storage stability of the meat was evaluated by microbiological analysis and measuring lipid oxidation in terms of thiobarbituric acid reactive substances (TBARS). HS resulted in significantly higher blood loss than GK. HS had significantly lower residual haemoglobin in LL muscle compared to GK. Slaughter method had no effect on rabbit meat lipid oxidation at 0, 1, and 3 d postmortem. However, at 5 and 8 days of storage at $4^{\circ}C$, significant differences (p<0.05) were found, with meat from the GK group exhibiting significantly higher levels of MDA than that from HS. At day 3, greater growth of Pseudomonas aeroginosa and E. coli were observed in the GK group (p<0.05) with B. thermosphacta and total aerobic counts remained unaffected by slaughter method. At days 5 and 7 postmortem, bacterial counts for all tested microbes were affected by slaughter method, with GK exhibiting significantly higher growth than HS. It can be concluded that slaughter method can affect keeping quality of rabbit meat, and HS may be a favourable option compared to GK due to high bleed out.

Background: Preventing oxidative stress in heat stressed animals may be possible by increasing antioxidant defence via exogenous administration of antioxidant substrate and/or its precursors. The study aimed to investigate the effect of Soursop juice in mitigating oxidative stress induced by heat stress in rabbit. Methods: Sixty mixed breed rabbit bucks aged 12-18 months old with the average weight of $1826{\pm}8.35$ g/rabbit, randomly allotted to experimental treatments of four replicates each, in a completely randomized design during high-temperature humidity index in Ado Ekiti, Southwest Nigeria. Soursop juice (SSJ) was administered via oral drenched daily per kg body weight (BW), to designated treatment 1 to 5; $0.55mlkg^{-1}BW$ distilled water (control), $0.55mlkg^{-1}BW$ SSJ, $1.11mlkg^{-1}BW$ SSJ, $1.67mlkg^{-1}BW$ SSJ and $2.22mlkg^{-1}BW$ SSJ, respectively. Fastened blood samples were collected at days 28 and 56, and assay for serum protein, cholesterol, triglycerides, superoxide dismutase, catalase, reduced glutathione and lipid peroxidation using standard procedures. Result: Result revealed that SSJ demonstrated hypocholesterolemic effect in a dose-dependent manner throughout the study. Effect of chronic administration of SSJ to heat stressed rabbits proved beneficial, as SSJ reduced serum lipid peroxidation and enhanced antioxidant activity over 8 weeks. Conclusion: Administration of soursop juice to heat-stressed bucks at $2.22mlkg^{-1}BW$ offered optimum antioxidant defense against oxidative stress.

Objective: Better feed efficiency can be achieved by selecting rabbit genotypes with lower residual feed intake (RFI) under high ambient temperatures. Methods: Two genotypes of rabbits (Jabali, Saudi local breed and imported, Spanish V-line) were used to derive RFI and to investigate the relationship between RFI and productive traits. In total, 250 animals (125 each) were housed in individual wire mesh cages in a semi-closed rabbitry. Growth performance, feed criteria, carcass evaluation, biochemical blood analysis, and immune responses were determined. Results: Superiority in growth performance, feed efficiency, carcass characteristics, and cellular immunity was recorded in the Jabali breed compared to the V-line genotype. According to regression analysis, a significant effect of daily body weight gain was found, upon computing the expected feed intake in both genotypes. Moreover, mid-body weight^0.75 had a significant effect only in the Jabali breed. Positive correlation coefficients between RFI and dry matter feed intake or feed conversion ratio were found. The same trend in this relationship between RFI and productive traits was observed in some cases for both genotypes. An opposite trend in correlations was observed in the studied genotypes for some traits. Conclusion: The results suggest that the relationship between RFI and productive traits must be taken into consideration in rabbit breeding programs under the prevailing environment. However, further studies are required to investigate the effect of rabbit genotype and environmental factors on computing RFI.

Phthalates are widely used as plasticizers to impart softness and flexibility to normally rigid polyvinylchloride products. However, there are not much studies jar dermal and ocular irritation toxicity of phthalates. So we investigated the skin or eye irritation effect of some phthalates which was not reported. The primary skin irritation of diethyl phthalate (DEP), diisodecyl phthalate (DIDP), diisononyl phthalate (DINP), dipropyl phthalate (DPP) and dipropyl phthalate (DPrP) was studied. The ocular irritation of dibutyl phthalate(DBP), DIDP, DINP, DPP and DPrP was also studied. DEP, DIDP, DINP, DPP, and DPrP were found to be non-irritating to the skin of the test animals. DBP, DIDP, DINP and DPP were found to be non-irritating to the eye of the rabbits. DPrP caused the slight irritations to the eye in 1 or 2 days after treatment but irritation of the animals was soon recovered.

Acute toxicity study was conducted on a Hepatitis B vaccine (Hepaccine-B-inj.) with mice, guinea pigs, and rabbits, in accordance with the norms suggested by the F.D.A. in U.S.A. Dose ranges were 2 doses/mouse, 5 doses/guinea pig, 10 doses/rabbit. They received the vaccine subcutaneously and intraperitoneally. Thereafter, all animals injected were observed of general signsdaily, and of body weight for two weeks. At the end of the observation period (or at the time of death), all animals received the highest dose group were autopsied and gross observation was made on various organs and tissues. No significant toxicity was noted.

Objectives : The prescription of Semyung-Gangji-tang, designed for the treatment of hyperlipidemia and atherosclerosis, consists of herbs good for treating blood stasis and phlegm stagnancy. It invigorates the liver, kidneys and spleen. Its medical nature is not too cold or too hot and increases human vital energy. The purpose of this study is to examine the curative effects of Semyung-Gangji-tang on atherosclerosis in hyperlipidemic rabbits. Methods : Twenty-four male NZW rabbits, around 2kg of body weight, were divided into 4 groups. Group I served as the normal group. Group II served as the atherogenic model group, fed a 1 % cholesterol diet for 8 weeks and sacrificed. Group III served as the atherogenic control group, fed with a 1 % cholesterol diet for 8 weeks and with a normal diet for the next 4 weeks. Group IV served as the treatment group treated the same as the control group and medicated with Semyung-Gangji-tang for the last 4 weeks. Three animals of group I and six animals of group n were sacrificed at 8 weeks. Five animals of group I , five animals of group III and IV were sacrificed at 12 weeks. Pathological examinations and image analysis were performed on the collected tissue samples. Results : The percentage of lipid deposition area of thoracic aortas of group IV($41.74{\pm}8.93%$) at 12 weeks was decreased compared with the group III ($71.30{\pm}12.74%$) at 12 weeks, but a statistical difference was not observed. The percentage of group IV at 12 weeks was significantly decreased (P<0.05) compared with the group n ($76.41{\pm}7.43%$) at 8 weeks. Histopathologically, advanced atheromas with calcification of aortic arches were observed in all animals of the control group at 12 weeks, but were observed in 2 animals of the treatment group at 12 weeks. Histopathologically, atheromas with calcification of thoracic aortas were observed with major atherogenic lesions in control group at 12 weeks, but simple fibro-fatty streaks were observed major atherogenic lesions in treatment group at 12 weeks. Conclusions : These results indicate that Semyung-Gangji-tang has antiatherogenic effects on experimentally induced atherosclerosis in rabbits.

We surveyed the antibody titers in the slaughtered pigs by enzyme immunodiffusion method for the epidemiological distribution of Aujeszky's disease in Korea. And also we observed the clinical symptoms, histopathological findings and antibody titers by serologic neutralization test in experimental animals infected with Aujeszky's disease virus(ADV) isolated from Korea. The results of the experiments were summarized as follows. 1. We detected 2 pigs infected with ADV of 1000 in 1990 and 1 of 600 in 1991 by enzyme immunodiffusion method. 2. In histopathological findings of experimental animals inoculated ADV, the typical characteristics of Aujeszky's disease were not observed in pig, but edema and degeneration in the epidermis were observed in rats, vasculoendotheriosis, perivascular cuffing and cellular infiltration in the cerebrum were appeared in rabbits and perivascular cuffing and forcal infiltration of glial cells in the cerebrum were appeared in mice. 3. The increasing antibody titers(1 : 64) in the serological neutralization test were ascertained in 2 carrier pigs inoculated ADV. 4. Rabbits, mice and rats died all about 5 days after inoculation, but pigs and chickens didn't die. 5. In 1 cat and 2 rabbits inoculated with the Aujeszky's disease virus(ADV), the typical clinical findings of Aujeszky's disease were observed in rabbit, but not in cat and so we slaughtered without any signs of Aujeszky's disease.

The aim of this study was to investigate food culture represented by the grain yard, water well, kitchen, and meat storage space which were depicted in the mural painting of An-Ak tomb No. 3. The mural paintings of An-Ak tomb No. 3 were compared with those of ancient Chinese tombs before the 4th century in order to understand their characteristics. Above all, the tomb murals describe the form and function of the stove (buttumak) as well as the cuisine using the cauldron (sot) and steamer (siru) in a very interesting manner. The meat storage space of An-Ak tomb No. 3 shows whole carcasses of animals such as roe deer, dog, and pig. However, Chinese murals show that while small animals such as soft-shelled turtle, fish, chicken, duck, pheasant, rabbit, etc. were stored as whole carcasses without being cut into pieces, large animals such as cows and pigs were slaughtered and each piece of their carcasses such as the head, thigh, meat loaf, and cardiopulmonary part was separately depicted. These tomb murals vividly describe the food culture of Koguryo and China before the 4th century.

Effect of inclusion of hard vs. soft wheat bran with different particle size on diet digestibility, growth performance and some slaughter traits was evaluated in fattening rabbits. Four isonitrogenous and isocaloric diets were used according to the origin of wheat bran (hard (HWB) - Triticum durum - and soft (SWB) - Triticum aestivum) combined with wheat bran particle size sieved by 2 mm (fine: 2) or by 8 mm (coarse: 8) in a bifactorial (2${\times}$2) study. A growth trial was conducted to measure the effect of treatments on performance in one hundred and twenty New Zealand White${\times}$Californian rabbits fed experimental diets from 50 to 87 days of age. Faecal apparent digestibility was determined within the last week in twenty animals per diet. Digestibility of nutrients was higher (p<0.05) in the diet containing HWB2, except for crude protein, ether extract and ash, than fine and coarse soft wheat bran diets. Final live weight, feed intake and feed consumption of rabbits on the diet with fine hard wheat bran were higher and resulted in greater daily weight gains (p<0.01) than for animals on the other diets. The slaughter yield and percentage value of organs were not significantly (p>0.05) affected by the diets fed; however, the diet containing fine hard wheat bran led to lower (p<0.05) percentages of skin, abdominal fat and carcass drip loss than the other dietary treatments. It is concluded that fine hard wheat bran can be better included in the diet than soft wheat bran to maximize growth performance without affecting carcass traits of fattening rabbits.
