  • The present study was carried out to investigate whether the aloe had a radioprotective effect in mice exposed to cobalt-60 gamma radiation or not. The survival ratio of mice for 30 days, hematopoiesis of blood-forming stem cells by spleen colony assay, chromosomal aberration frequency of bone marrow cells and histopathological findings of bone marrow were investigated. The survival ratios of aloe administered groups with concentration of 250, 500, 1,000 and 1,500mg for 3 days before irradiation and control group in cobalt-60 gamma irradiated mice(700rads whole body irradiation, dose rate of 50rads/min.) were 77.4, 79.3, 80.6, 90.0 and 53.1%, respectively. The survival ratios of pre-irradiation aloe administered groups were superior to those of post-irradiation aloe groups and control group. In spleen colony assay, Aloe vera administration before irradiation enhanced the recoveries of numbers of blood-forming stem cells of bone marrow of irradiated mice. There were decreased chromosomal aberrations of bone marrow cells at the first day after irradiation in aloe administered groups compared to that of control group. Histopathological findings in the bone marrow of irradiated mice were hypocellularity due to the depletion of myelocytes, abundant of fat vacuoles and these changes were weakened in aloe administered groups compared to that of control group.

  • A 7-year-old, castrated, male Maltese dog presented with hyporexia and depression for 3 days. Elevated serum amylase, lipase activities, and liver enzyme values were found upon blood examination. An abdominal mass was seen on radiographs caudal to the gastric body in the left middle abdomen. In the left middle abdomen, abdominal ultrasonography also revealed a massive, irregularly marginated, heterogeneous mass of unknown origin, and in the right cranial abdomen, heterogeneously hypoechoic pancreatic tissue and hyperechoic change of adjacent mesenteric fat were observed. Contrast-enhanced computed tomography showed an irregular contour of the left pancreatic limb as well as heterogeneously enhanced parenchyma. A low-attenuating peripancreatic fluid collection with a thin and irregular wall was also seen. Based on these findings, an atypical pancreatic abscess with necrotizing pancreatitis which manifested as walled-off necrosis was suspected. The mass was excised, and the pancreatic abscess was confirmed by histopathologic examination. No complications were found in the patient after two months of follow-up examination.

  • In this experiment the effect of dietary carob pods in the growth performance of fattening pigs and their meat quality, including steak chemical composition and fatty acid profile, were examined. A total of 160 weaning piglets, 30 days old, were allocated into four equal groups with 4 subgroups of 5 female and 5 males each. The animals were fed with isocaloric and isonitrogenous diets, containing either 0 or 75 or 100 or 125 g of carob pods per kg of feed. At the end of the experiment, on the 180 day of age, carcass subcutaneous fat thickness, steak chemical composition and steak fatty acid profile were determined. The results of the experiment showed that the dietary addition of 75 or 100 g/kg carob pods increased body weight at slaughter and carcass weight. No significant effect was noticed on the other examined carcass parameters. Consequently, carob pods could be suggested as a potential feed for fattening pigs without any adverse effect on their meat quality.

  • Vitamins and minerals categorized as micronutrients are the essential components of animal feed for maintaining health and improving immunity. Micronutrients are important bioactive molecules and cofactors of enzymes as well. Besides being cofactors for enzymes, some vitamins such as the fat-soluble vitamins, vitamin A and D have been shown to exhibit hormone-like functions. Although they are required in small amount, they play an influential role in the proper functioning of a number of enzymes which are involved in many metabolic, biochemical and physiological processes that contribute to growth, production and health. Micronutrients can potentially have a positive impact on bone health, preventing bone loss and fractures, decreasing bone resorption and increasing bone formation. Thus, micronutrients must be provided to livestock in optimal concentrations and according to requirements that change during the rapid growth and development of the animal and the production cycle. The supply of nutrients to the animal body not only depends on the amount of the nutrient in a food, but also on its bioavailability. The bioavailability of these micronutrients is affected by several factors. Therefore, several technologies such as nanoparticle, encapsulation, and chelation have been developed to improve the bioavailability of micronutrients associated with bone health. The intention of this review is to provide an updated overview of the importance of micronutrients on bone health and methods applied to improve their bioavailability.

  • This study was performed to investigate nutritional effect and the utilization possibility of rapeseed oil which could replace the imported edible oils and oil crops. The proximate compositions of a recommendable cultivar(Mokpo Dangyo 19) and a native kind(Asahi) and the characteristics of these rapeseed oils were analyzed. The animal experiment of these rapeseed oils was carried out during 8 weeks of growing periods after weanling. Forty male weanling Sprague-Dawley rats were randomly assigned to 3 diet groups of Dangyo 19 oil, Asahi oil and commercial Soybean oil. Mokpo Dangyo 19 variety contained more lipids than Asahi variety by 8% and there was no difference in physiochemical characteristics between Dangyo 19 oil and Asahi oil except that erucic acid was contained little in Dangyo 19 oil but 50% in Asahi oil. Body weight gain, FER(Feed efficiency ratio) and PER(Protein efficiency ratio) of rats fed Dangyo 19 oil were higher than those of rats fed Asahi oil and organ weights such as liver, kidney and epididymal fat pads weights of rats fed Dangyo 19 oil were significantly higher(P<0.05) thanthose of rats fed Asahi oil. the apparent digistibility of total diet and total lipid were higher in rats fed the diets containing Dangyo 19 oil than Asahi oil. The content of total lipid in heart in heart were not significantly different with dietary oil kinds. The content of total lipid in liver increased with age in all rapeseed oil groups.

  • This study examined the effect of dietary lipids and ovariectomy(OVX) on bone mass in rats. The experimental animals were divided into sham operation(S) or OVX(O) groups and then each group was divided into soybean oil(SS, OS), beef tallow(SB, OB), and fish oil(SF, OF) diet group. Experimental diets were fed for 16 weeks. Weight gain tended to be higher in OVX groups than in sham groups. Weigth gain was the highest in beef tallow group (SB) and the lowest in fish oil group(SF). There were no difference in weight, length, breaking force, strength and circumference of femur mong groups. However, volume of femur tended to be higher in OVX groups than in sham groups. Ash content of femur was significantly lower in OVX than sham groups but there were no difference between SB and OB group. Ca content in the soybean oil and beef tallow group were not influenced by OVX but Ca content in fish oil group was significantly higher in OF than SF group. The SB group showed the hyighest Ca content and the SF group showed the lowest Ca content. P content of femur was significantly lower in OVX groups than in sham groups but there were no difference between SB and OB group. The SS group showed the highest P content and the OS and OF group showed lower P content compare to other groups. From this result, it suggested that beef tallow positively influenced maintenance of bone mass by means of accumulation of body fat in ovariectomy.

  • A total of 252, 50 week-old Isa-brown laying hens were randomly allotted to 7 groups of 3 replicates. Mustard meal (MM) which is a by-product from mustard processing plant, was dried under the sun or in a gas heated pan. It contained on DM basis 30-32% CP, 19-22% EE and 12-13% CF. The meal from either drying method was incorporated into the diets at 0, 10, 20 and 30% which was equivalent to the substitution levels for soybean meal at 0, 31, 63 and 94%, respectively. All birds were individually kept in battery cages where feed and water were freely accessed throughout 84 days experimental period. It was found that egg production, feed intake, body weight gain and egg weight significantly decreased with the increased MM level. The inclusion of 20% MM did not show a significant difference in egg production and quality from the control, but produced 6-8% lower egg production. Feed intake was linearly decreased with the MM levels, except the 10% sun dried MM group. Fat deposition of the birds fed MM diets significantly decreased, while kidney weight increased when compared with the control group. However, the weight of thyroid glands and spleen trended to be heavier in the MM groups, but this was not significantly different among dietary treatments. It was concluded, MM from both drying methods could be incorporated in laying hen diets at the level of 10% without any adverse effect.

  • Sixteen Large $White{\times}Landrace$ pigs 12 weeks of age, with an average body weight of $22.9{\pm}2.12kg$ were fed four experimental diets; a commercial grain-based grower diet (control); or a diet containing 20% of either sun-dried leucaena leaf meal (LLM), water soaked LLM or $FeSO_4-treated$ LLM, replacing the basal diet. There was a significant (p<0.05) decrease in live weight gain, feed intake and feed conversion efficiency (FCE) in pigs fed the diet containing sun-dried LLM. Growth rate, feed intake and FCE were not affected by the addition of water-soaked and FeSO4-treated LLM to the basal diet. Triiodothyronine $(T_3)$ and thyroxine $(T_4)$ levels in the blood plasma were not affected by the dietary treatments. Addition of $FeSO_4-treated$ LLM to the basal diet significantly (p<0.05) reduced the back fat thickness of the pigs.

  • Fifteen intact male Jamunapari goats, average body weight $22.0{\pm}1.18kg$ were divided into three groups of 5 animals in each to investigate the effects of feeding leucaena on energy retention and distribution of retained energy. Leucaena leaves and twigs provided 0%, 25% and 50% of CP in the rations of animals in $L_1$ (control), $L_2$ and $L_3$ groups, respectively. Energy balances were determined in an open circuit respiration chamber from gaseous exchange and nitrogen carbon balances. Energy retentions calculated from gaseous exchange data were 181.6, 190.0 and 172.8 kJ/kg $W^{0.75}/d$ and from carbon-nitrogen balances were 178.2, 199.5 and 171.1 kJ/kg $W^{0.75}/d$ in $L_1$, $L_2$ and $L_3$ groups, respectively. No significant difference was observed among the groups in both the methods. The retention of nitrogen and energy in the form of protein was similar in different treatment groups. Similarly, no significant effect was observed on energy retention in the form of fat and total energy retention due to incorporation of leucaena in the diets.
