Insect/worm is a source of protein food, more calcium than you think, made up of low-fat and high protein in the worms, 20% of the entire protein, nutrients, and so. because of this, the value of any insect food will rise. Is not argued that enough, livestock methane from gaseous material of the earth temperature no phi but not small role, and indeed. If a non-carbone missions from livestock are less and consequently the production of biofuels using worms because it is also expected to be available to the worms in cattle, such as no benefit is expected that you will be spotlighted.

The objective of this study was to investigate effects of dietary level of CLA and the duration of feeding CLAcontaining diets on reproductive performance in sows and piglet growth rate. Tallow (3% in gestation diet and 5% in lactation diet, respectively) was incorporated as a fat source in control diet, and each 50% (dietary CLA level of 0.75% in gestation diet, and 1.50% in lactation diet, respectively) or 100% (dietary CLA level of 1.50% in gestation diet, and 2.50% in lactation diet, respectively) of tallow was replaced by a commercial CLA preparation containing 50% CLA isomers. Diets containing CLA were fed either from d 15 premating to weaning or d 74 post-mating to weaning. The level of dietary CLA and feeding duration did not affect litter size. High dietary level of CLA, however, decreased piglet weights at birth (p<0.01) and tended to decrease backfat thickness of sows at weaning. Longterm feeding of CLA-containing diets decreased piglet weights at weaning (p<0.05) and backfat thickness of sows at weaning (p<0.05). CLA supplemented in sow diet was transferred to fetus and piglets during pregnancy and nursing period, respectively. CLA contents of femoral muscle of piglets were 2.08 to 2.57 mg per g of fat at birth, and 2.36 to 4.47 mg at 10 days of age in CLA groups, while CLA was not detected in the control group. In conclusion, dietary supplementation of CLA tended to lower backfat thickness of sow and piglets' weight at birth or weaning, but did not affect total litter size. Dietary CLA was transferred efficiently during prenatal and postnatal periods of time through the placenta and milk, respectively.

For the purpose of disinfection and efficient storage, Korean Paldal variety rice was hulled into the unpolished and polished ones and packed in the kraft paper bags, irradiated with relatively high doses, 500, 800, and 1,000 krad from the $CO^{60}$ source and stored at room temperature, a variety of changes were observed as follows. 1) With 1,000 krad irradiation, mold was almost sterilized. 2) Fat acidity increased during storage and continued to increase more with increased doses. 3) The content of riboflavin eras severely reduced with higher doses. 4) The results of organoleptic test were featured by a yellow color and a keen irradiation odor appearing in the boiled rice. 5) In the irradiated rice starch with 3,000 krad, hydrolysis with ${\alpha}$-amylase was not effective while accelerated with diastase.
An attempt was made to evaluate the effects of total mixed rations (TMR) containing 17.5% forage neutral detergent fiber (NDF) from paragrass, paragrass+cassava chips and corn silages on the performance of dairy cows in the tropics. Experimental dietary treatments contained a similar content of total NDF, total non-fiber carbohydrates, crude protein and energy. Maximum and minimum temperature humidity index during the experimental period were 79.1-80.6 and 66.8-68.6, respectively. Among silage sources, there were no differences (p>0.05) in concentrations of acetic and propionic acids and butyric acid was undetectable. Concentration of lactic acid was higher (p<0.01) in corn silage but its pH was lower (p<0.01) than in paragrass and paragrass+cassava silages. Dairy cows on TMR containing corn silage not only gained more weight (161 and 46 vs. -189 g/d) but also consumed more feed (18.47, 15.84 and 14.49 kg/d), and produced more milk (23.89, 22.03 and 20.83 kg/d), 4% fat corrected milk (25.47, 24.05 and 22.02 kg/d), solids-not-fat (1.99, 18.3 and 1.73 kg/d) and total solid (3.10, 2.85 and 2.64 kg/d) compared with those on TMR containing paragrass+cassava and paragrass silages, respectively (p<0.01). Dairy cows on TMR containing paragrass+cassava silage were better in these respects (p<0.01). These results suggest that in formulating diets on an equal NDF basis for different forage qualities, diets higher in forage quality can stimulate higher DMI for dairy cows in the tropics and thus improve productivity.
As the elderly population has increased in recent years in Korea chronic degenerative diseases prevalent in the aged have garnered attention in relation to food behavior. In general, dietary intakes of elderly Koreans were inadequate in quality as well as in quantity. Especially, intakes of Ca, vitamin A, and riboflavin along with total energy were insufficient. They tended to consume high carbohydrate and low fat energy rates which may be resulted from long standing vegetable-based flood patterns. Relationships between dietary intakes and indices of cardiovascular diseases revealed that blood pressures and serum lipids patterns tended to be poor in individuals having high abdominal fat accumulations which seemed to be related with dietary consumption of high carbohydrate and insufficient intake of many nutrients. These results suggested that a nutritionally balanced diet including animal sources floods is needed in order to prevent an abdominal obesity and cardiovascular diseases. The bone health status of the Korean elderly appeared poor. It was more serious in women recording a higher prevalence rate of osteopenia and osteoporosis than in men. There were strong associations between dietary factors and bone health status. Bone mineral density was found to be higher with higher intakes of protein energy rate, the total amount of feeds, and many nutrients including Ca and p, indicating that a good quality diet is essential in maintaining healthy bone status in later life. mental health condition of the elderly as measured by cognitive function and the degree of depression was also inadequate and had strong association with dietary consumption. The positive results were obtained in individuals having an adequate dict. Therefore, it could be summarized that the physical as well as mental health in elderly Koreans are highly related with their dietary patterns. Thus, the older adults need te consume nutritionally well balanced diet in sufficient amount, which contains various flood items including significant amounts of animal source floods in a daily diet in order to maintain healthy condition.
This study was conducted to investigate the effects of feeding different carbohydrate sources and garcinia cambogia extract(HCA) on body weight and lipid metabolism. Fifty 10-month-old male Sprague-Dawley rats weighting $635{\pm}6g$ were randomly divided into 5 groups and fed different experimental diets for 4 weeks. The carbohydrate(CHO) sources of each group were cornstarch(control group, 100% of CHO), fructose(F group and FH group, 25% of CHO) and sucrose(S group and SH group, 25% of CHO). FH group and SH group were fed diets containing 1%(W/W) of HCA. Food intake, body weight gain, and calorie efficiency were not significantly different among the groups. Perirenal fat pad weight of FH group was significantly lower than F group, but epididymal fat pad weight was not different among the groups. Fasting glucose level were not significant among the groups. Plasma lipid profile of FH or SH group was slightly lower than F or S group, respectively. The degree of difference of plasma lipid level was greater between F and FH group than those of between S and SH group. In liver, total lipid, triglyceride and total cholesterol level were slightly higher in F group than S group, and tended to be lower in FH group than F group, but tended to be higher in SH group than S group. Liver citrate lyase activity were not significant among the groups. These results suggest that HCA is potential material for reduction of body weight and improvement of plasma lipid profiles. But, there was no difference between fructose intake with HCA and sucrose intake with HCA in reduction of body weight and lipid metabolism.
The prevalence rate of thyroid dysfunction (hypothyroidism and hyperthyroidism) has increased within the Korean population and seems to be affected by iodine dietary habits. Some studies reported that the prevalence of thyroid dysfunction increase both in the area of iodine deficiency and excess. In this study, we tried to discover the difference in iodine intake, anthropometric measurements, and blood parameters between male subjects with or without subclinical thyroid dysfunction. A total of 5,249 subjects (Euthyroid: 4706, SubHypo: 454, SubHyper: 89) were used in this study. There were no significant differences in BMI, body fat, visceral fat, waist circumference, SBP, DBP, total cholesterol, HDL-cholesterol, LDL-cholesterol, TG, fasting serum glucose, HbA1c, alcohol intake, however significant differences were noticed in both age and smoking status. Through a food frequency questionnaire (FFQ), iodine intake per day was estimated. The average iodine intake was similar (SubHypo $392.9{\pm}279.0{\mu}g$, Euthyroid $376.5{\pm}281.7{\mu}g$, SubHyper $357.3{\pm}253.8 {\mu}g$) among groups. The main source of iodine intake was eggs (52.8%, 54.2%, 52.4%) followed by milk (16.3%, 15.8%, 17.8%), then sea mustard & sea tangle (12.4%, 11.9%, 11.6%). The prevalence of subclinical hypothyroidism and subclinical hyperthyroidism was higher in subjects whose intake was higher than the recommended nutrient intake (RNI). These results suggest that the excess consumption of iodine intake may act as one of the risk factors regarding thyroid dysfunction in Korea. Therefore, an adequate amount of iodine intake is necessary in order to prevent subclinical thyroid dysfunction and clinical thyroid dysfunction.
The aim of this study was to investigate the effects of L-carnitine on the components of serum and liver and the effects on the anti-oxidant system. For this purpose, five experimental groups were setup. For fat source, perilla oil enough with unsaturated fatty acid and beeftallow enough with saturated fatty acid were supplemented together with L-carnitine to the rats. Five experimental groups kept eight Sprague-Dawley rats respectively, They were co group supplemented with basic diet or AIN-93, PO group supplemented with perilla oil, POC group supplemented with perilla oil and L-carnitine, BT group supplemented with beeftallow, and BTC group supplemented with beeftallow and L- carnitine. The results are. 1) Weight gain, food intake and FER were not different significantly among the experimental groups. 2) Significant difference was observed in serum total lipid(P<0.05), serum triglyceride(P<0.05), serum total cholesterol (P<0.05)and serum LDL cholesterol(P<0.05). Serum total lipid and serum triglyceride were significantly low in the groups supplemented with L-carnitine. Serum total cholesterol showed difference with the supplementation of L-carnitine in BTC only. LDL cholesterol showed no significant difference with the supplementation of L-carnatine, but total values of LDL-cholesterol were high in groups supplemented with beeftallow. 3) Total cholesterol in liver was low in POC group with the supplementation of L-carnitine however, there was no difference in BTC group with the supplementation of L-carnitine. In summary, dietary L-carnitine did not influence the weight gain, food intake and food efficiency ratio among the experimental groups, but had an effect of lowering the serum total lipid and triglyceride significantly in both groups which were supplemented with L-carnitine. The effect of lowering of sew total cholesterol with the supplementation of L-carnitine in beeftallow group(BTC) only. The effect of lowering of liver total cholesterol with the supplementation of L-carnitine in perilla oil group(POC) only.
Growth and feeding studies were conducted to determine effects of hazelnut kernel oil meal (HKOM) on growth performance (as protein efficiency), and milk production and composition. In the growth study, 24 individually fed Karayaka lambs (4 mo. and 25.55 kg LW) were used to determine protein efficiency calculated using the Slope Ratio Technique. In the feeding trial, 4 Jersey cows were arranged in $4{\times}4$ Latin squares experiment to measure effects of diets containing HKOM, soybean meal (SBM) corn gluten meal (CGU) and urea (U) on milk production and composition. Protein efficiencies for HKOM, SBM and CGM were found as $1.342{\pm}0.499$, $0.879{\pm}0.488$ and $1.833{\pm}0.893$, respectively. Milk production for the cows consuming concentrates, containing HKOM, SBM, CGM and U, were $13.97{\pm}0.99$, $13.20{\pm}1.09$, $14.86{\pm}0.68 $ and $13.06{\pm}1.23kg/d$ (p<0.01), respectively. There were no differences (p>0.05) among diets for milk protein content were statistically different (p<0.05), although milk DM and fat percentage as well as milk solids-not-fat and lactose percentage (p<0.01). The highest DM intake was associated with the U diet, intake was intermediate with the SBM and HKOM diets, and the lowest with CGM diet (p<0.05). In conclusion, there data may indicate that the HKOM is useful in diets as a protein source for growing ruminants and lactating cows.

This study was conducted to investigate the effects of replacing whole crop corn silage (WCCS) with whole crop rice silage (WCRS) in the total mixed ration (TMR) on nutrient intake, milk yield and its composition in Holstein cows. The Chucheong rice variety (Oryza sativa L. Japonica) and corn (Pioneer 32 P75) were harvested at yellow-ripe stage and were ensiled in round bales and in trench silos, respectively. Two TMR containing either WCCS or WCRS were prepared. These diets were randomly assigned to 16 midlactating Holstein cows (8 cows per treatment) and were fed for 120 days. The first 20 days were used for dietary adaptation and for the next 100 days daily feed intake, milk yield and its composition were recorded. The pH, lactic acid, NDF, ADF, CP, Ca and P contents were similar in WCRS and WCCS. The DM, ash and EE contents of WCRS were greater compared with WCCS. Nutrient (DM, NDF, TDN and CP) intakes were similar in cows fed WCCS- and WCRS-based TMR. Daily and 4% fat corrected milk yield were not affected by the treatments. Milk composition (percent milk fat, protein, lactose and total solids) was similar in cows fed either WCCS- or WCRSbased TMR. The concentration of milk urea N was greater in cows fed WCRS-based TMR than those fed WCCS-based TMR. In conclusion, round-baled WCRS can replace WCCS in the diet of mid- to late-lactating Holsteins without any deleterious effects on feed consumption, milk yield and its composition. The present findings raise the possibility that WCRS can be used as an alternative roughage source in the diets of dairy cows in countries with surplus rice production.
