An experiment was carried out to study the effect of environmental color on the eating behaviour in broiler chicks. A total of ninety broilers with average 350g of initial body weight were randomly assigned in the $3{\times}3$ randomized complete block design with 3 treatments(yellow, blue, red) and 10 birds per replication of various environmental color at walls, feeders and electric bulbs. The results obtained from these experiments are summarised as follows: 1. Feed Intake and average daily gain were significantly(P<0.05) increased by yellow colored environment. 2. Eating time and eating rate were significantly higher in the red colored than the other, indicating that yellow colored environment would maximize body weight gain and feed conversion for broiler chicks.

Sixteen Korean native bulls weighing about 211 kg were randomly allotted to investigate the effect of different dietary calcium levels on performance. Feeding period was divided into growing period and fattening period for 180 days. Four calcium levels (0.44, 0.58, 0.72 and 0.86%) were used to each period. Bulls fed the diet containing 0.72% calcium had greater body weight gain and consumed more feed than bulls fed diets containing 0.44, 0.58 and 0.86% calcium and improved in feed efficiency. Bulls fed the diet containing 0.44% calcium were worst in performance. It can be concluded that Korean native bulls in growing and fattening period required no more than 0.72% calcium in diet that contained 0.55% phosphorus, and appeared that when ratio of calcium to phosphorus intake was 1.45, performance of Korean native bulls was most beneficial.

Effects of zinc chloride (Zn) on the immune responses of lipopolysaccharide (LPS) were studied by using ICR mice. Mice were divided into 4 groups (10 mice/group), and Zn was given to the mice with i.p. injection at 0.3 mg/kg 5 times a week for 14 days, and 1 hr after Zn administration, LPS was given with i.p. injection at 5 mg/kg twice a week. Mice were immunized and challenged with sheep red blood cells (SRBC). Immunobiological responses were evaluated by humoral, cellular and nonspecific immunity. LPS treatment significantly increased the relative weights of spleen and thymus, hemagglutination titer (HA) and proliferation of splenocytes compared with those in controls, but significantly decreased the body weight gain. Zn treatment significantly increased proliferation of splenocytes and circulating leukocytes compared with those in controls. Combination of Zn and LPS significantly decreased the body weight gain and proliferation of splenocytes compared with those in controls. Combination of Zn and LPS significantly decreased HA and proliferation of splenocytes than in LPS alone. These findings indicate that zinc lowered the humoral immune responses of LPS.

The experiment was undertaken to see the effects of Bacillus sp. on the growth performance and disease resistance to Salmonella sp. infections. The use of probiotic microbes in poultry is commonly practiced. In this study, Bacillus subtilis was tested using a total of 120 chicks of age of 1 day after hatching. The growth traits examined were body weight gain and feed conversion rate. And also, the Salmonella resistance of Bacillus subtilis was tested after the chicks were orally administered with Salmonella pullorum by gavage force injections. The result showed that Bacillus subtilis yielded a high feed efficiency, consequently increased growth rate. For the effect of Bacillus subtilis on Salmonella infection, Bacillus subtilis significantly improved the resistance to Salmonella pullorum infection. Various clinical symptoms of Salmonella infection were highly decreased by addition of Bacillus sp.

This study investigated the potential effects of amitraz on the pre- and postnatal development, behavior, and reproductive performance of offspring of parent rats given amitraz during pre-mating, gestation, and lactation. The test chemical was administered via the drinking water containing 0, 40, 120, and 360 ppm to male rats from 2 weeks before mating to the end of 14-day mating period and to females from 2 weeks before mating, throughout mating, gestation and lactation up to weaning. Based on fluid consumption, the male rats received an average of $0,\;5.7{\pm}1.33,\;13.2{\pm}2.08,$ and $35.8{\pm}3.42$ mg/kg/day amitraz, and the female rats received an average of $0,8.7{\pm}4.42,\;20.1{\pm}9.60,\;and\;47.6{\pm}22.38$ mg/kg/day amitraz, respectively. At 360 ppm, an increase in the incidence of abnormal clinical signs, a suppression in the body weight gain, a decrease in the food consumption and litter size, an increase in the post-implantation loss, and a decrease in the seminal vesicle weight were observed in the parent animals. In addition, a suppression in the body weight gain, a decrease in the grip strength, a delay in the negative geotaxis, an increase in the pre- and post-implantation loss, and a decrease in the number of live embryos were observed in the offspring. At 120 ppm, suppressed body weight gain and reduced food consumption were observed in the parent rats. Suppressed body weight gain and decreased grip strength were also observed in the offspring. There were no signs of either reproductive or developmental toxicity at 40 ppm. Under these experimental conditions, the no-observed-adverse-effect level of amitraz for parent rats and their offspring was estimated to be 40 ppm in rats.

The present study investigated effect of supplementation of agricultural byproduct on growth performance and blood parameters of broiler chicken using meta-analysis. Total 11 studies (32 experiments) where broiler feeding trials with agricultural byproducts were included were employed in analysis. All studies were conducted at commercial farm placed in South Korea and under commercial feeding programs. Growth phases were divided into two groups based on slaughter day. For growth performance, body weight, body weight gain, feed intake and feed conversion rate (feed/gain) were investigated. Carcass weight, dressing percentage, liver and spleen weight, blood glucose, total cholesterol and triglyceride, HDL (High density lipoprotein) and LDL (Low density lipoprotein) cholesterol contents in blood were investigated. Body weight of broiler of treatment was significantly increased than the control (P<0.05), regardless of growth phase. However, body weight gain during late growth phase did not show significant difference between control and treatment. Effect evaluated by random effect model on feed intake was not significant. Effect on feed conversion rate during early growth phase was significantly negative (P<0.05). Effects on carcass weight, dressing percentage, liver and spleen weight were not significant in random effect model. Effect on abdominal fat was significantly negative (P<0.05). In blood parameters, significant effects were found at total cholesterol, triglyceride and HDL cholesterol (P<0.05). Effect on HDL cholesterol only was positive effect, and others were negative.

This study examined how the daily administration of dried CP roots affects body-weight gains of mice. An aqueous CP extract (1 g/kg of CP-W) was orally administered to mice on a daily basis for ten weeks, and the mice's body weights and food intakes were measured throughout the period. At the end of the ten-week treatment, murine blood samples were taken and hematological and serum biochemical parameters were examined. The mice's intra-abdominal organs were weighed at necropsy. The treatment of CP-W significantly suppressed the mice's body-weight gain by about 10%. There were no changes to the food intakes of and no observable abnormal clinical signs in any of the animals throughout the experimental period. There were no significant differences between the control and CP-W mice in regards to the hematological and serum biochemical parameters and the organ weights at necropsy. The results demonstrated that the daily administration of CP-W for ten weeks suppresses body-weight gain in mice and does not change mice's food intake or cause any noticeable toxic effects.

Arginine is one of the basic aminoacid found to be associated with histones and also one of the essential aminoacids now. Arginine is provided by diet, and also found to be synthesised in the body through intestinal-renal axis. Justification---BMI---Associated Risks-How to gain body weight---Healthy. Foods to Gain Weight Fast---High-Protein Vegetables and Fruits(with Image)-Recipes---Physical exercises-List of fruits and vegetables grown in Bangladesh with local names, English names and Botanical names-taxonomic family names. Arginine as drug was first approved by FDA and has recognised as a excellent dietary supplement for curing diseases like preeclampsia during gestation, diabetes and insulin resistance in obese patients. Preeclampsia is characterised by high blood pressure and proteinuria in gestational period of after 20 weeks. Severe preeclampsia is characterised by headaches, blurred vision, and inability to have high photovision, nausea and vomiting. L-Arginine along with Vit C and E are given as medical food to the patients and decrease in condition symptoms is the project now under phase II clinical trial. However the role of arginine in ameolirating preeclampsia symptoms is uncertain except with that of hypertension. Arginine is used to treat pain in sickle cell anaemia, lung damage, reperfusion injury, Trauma and shock but should be excluded during sepsis.

This study examined the weight control and food habits in 160 obese children and 191 normal-weight children in 4th, 5th and 6th graders of some elementary schools in Gumi city. Regarding the subjects' self-recognition of their body shape, 27.8% of the normal weight group and 92.5% of the obese group acknowledged themselves to be obese. 58.9% of the normal weight group and 61.0% of the obese group were not satisfied with their own body shape and the difference between two groups was very small, 23.6% of the normal weight group and 87.5% of the obese group have tried to reduce weight. The main causative factor of weight gain that children themselves recognized was a sedentary life style. All the students showed a high rate of irregular and unbalanced diet. The obese children showed a significantly higher rate of skipping meals and eating meals faster than the normal weight children. More obese children disliked exercise, and did less excercise than the normal weight children. There was a negative correlation between the obesity index and the food habit score. In other words, they frequently skip a meals, eat in a hurry and dislike vegetables and dairy products. In addition, there was a positive correlation between the student's BMI and the parents' BMI. Overall, many normal weight children showed a high level of self-consciousness of being obese or underweight. Both groups showed a low degree of satisfaction with their own body shape. Therefore education for the distorted perception of body shape is needed because, even normal weight children have tried to reduce their weight. Obese children should be encouraged to exercise, not skip a meals and eat slowly. They also need a systematic education program on weight reduction and weight maintenance. Moreover, education on a healthy diet, healthy food habits, and healthy body shape are necessary for elementary school children.
