In this study we investigated the antidiabetic and hypolipidemic potential of dried powdered leaves of Gymnema sylvestre (GS). The acute effect of GS administered by oral gavage on glucose blood level of and lipids in non-diabetic and alloxan-diabetic rats were investigated in the following conditions: a) after a balanced meal; b) after the ingestion of 1000 mg/kg amylose or 1000 mg/kg glucose; c) after the ingestion of a mixture of 12 mL/kg soybean oil + 1% cholesterol (SOC). In addition, the effect of the treatment with GS during two (sub-acute) or four weeks (chronic) on body weight, food and water ingestion, glucose blood level and lipids in non-diabetic and alloxan-diabetic rats were measured. The dose of GS utilized in the majority of the experiments, i.e., 30 mg/kg, corresponds to that given to treat diabetes in Brazil. GS acutely did not influence the elevation of glycemia promoted by a balanced meal or by the administration of amylose or glucose; but promoted more intense (P<0.05) elevation of serum lipids after the administration of SOC. Moreover, the sub-acute and chronic treatment with GS in non-diabetic and alloxan-diabetic rats did not change: a) the body weight gain; b) food and water ingestion; c) the blood level of glucose and lipids. Thus we concluded that GS, at least in the form commercialized in the Brazil, i.e., dried powdered leaves, require further experimental and clinical trials before being recommended to treat diabetes and hyperlipidemia.

Diabetes mellitus has developed into one of the debilitating diseases disturbing the health of many people living with cardiovascular diseases in modern times. The root of Ageratum conyzoides was investigated for its effects on alloxan-induced diabetic Wistar rats’ cardiac tissues. Thirty-two (32) Wistar rats weighing between 180 and 190 g were randomly divided into four groups. The animals in groups B-D were induced with a single dose of 150 mg/kg body weight of alloxan (ALX) intraperitoneally. They were confirmed hyperglycemic after 72 hours of induction and then sustained in hyperglycemic condition for 2 weeks. Animals in groups C and D received AC intervention, as stated above, for four weeks. The body weight of the experimental animals and blood collection for glucose estimation were taken weekly for six weeks using appropriate instruments. Biochemical assays for lipid profile, antioxidant enzymatic, and nonenzymatic markers were carried out. Histopathological changes in the cardiac tissues were also studied. Administration of 150 mg/kg of ALX to experimental rats induced diabetes and significantly reduced the body weights, significantly ( p < 0.05 ) increased the glucose level, triglyceride (TG), total cholesterol (TC), and low-density lipoprotein (LDL) levels, and decreased the levels of high-density lipoprotein (HDL) and antioxidant enzymatic markers such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx) while the antioxidant nonenzymatic marker such as malondialdehyde (MDA) level was significantly increased. By contrast, rats given the ethanolic extract root of A. conyzoides had significantly ( p < 0.05 ) increased the body weight gain, whereas the glucose levels significantly ( p < 0.05 ) improved in treated diabetic rats. This extract also improved the cardiovascular system of the diabetic rats by significantly decreasing TG and LDL levels, significantly ( p < 0.05 ) increasing the HDL level, significantly reducing the cardiac contents of CAT, SOD, and GPx, and significantly ( p < 0.05 ) decreasing MDA. Ethanolic extract root of A. conyzoides exhibited antihyperglycemic and antihyperlipidemic activities and mitigates damage to the heart from the ALX-induced myocardial toxicity associated with type-1 diabetes.

The current study aimed to determine the potency of aqueous extract of grape fruit (Naringin) in lowering blood glucose and lipid profile in streptozotocin induced diabetic male rats (by single injection of Streptozotocin at the dose of 60 mg/kg of the body weight). Naringin was extracted from grapefruit albedo (white inner Pell) by using aqueous hydrolysis, then it was identified on Thin Layer Chromatography (TLC).The results of thin layer chromatography have showed that Rf values was 0.75 in aqueous extract compared with Rf standard naringin (0.76).Twenty four adult male rats were randomly assigned to three equal groups treated for 30 days as follows: Intact control (C) , Diabetic Control (D.M.), treated diabetic rats (T) received (80mg/kg B.W.) of flavonoids (naringin). Blood sample were obtained befor and after 10,20 and 30 days from treatment. The results showed significant decrease in body weight , blood glucose , cholesterol, and triglyceride in T group. These results showed that naringin has potential hypoglycemic and hypolipidemic effect in streptozotocin induced diabetic rats.

The present study aims to evaluate the ameliorative effect of crude and solvent partitioned fractions of Gymnema sylvestre in alloxan-induced hyperglycemic and dyslipidemic rats. The extract and fractions of Gymnema sylvestre were administered to alloxan (120 mg/kg) induced diabetic rats at doses of 100, 300, and 600 mg/kg. Metformin (100 mg/kg) was used as the reference drug. All treatments were administered daily for 14 days through the oral route. Effects of the treatments on blood glucose levels, body weight, and serum lipid profiles were monitored. The results revealed that all the extracts and fractions were able to reduce the blood glucose levels and improved the body weight of diabetic rats, with more pronounced effects at the treatment of 300 mg/kg of crude methanol and ethyl acetate fraction. The blood glucose of diabetic untreated rats continued to increase up to the time of euthanization. There were significant reductions (p<0.05) in the levels of serum total cholesterol, triglyceride, and low-density lipoprotein cholesterol (LDL-C) of all the treated groups when compared to the diabetic untreated. However, a significant (p<0.05) decrease in the serum concentration of highdensity lipoprotein- cholesterol (HDL- C) was observed in the diabetic untreated rats when compared to the HDL-C levels in the treated rats. The ameliorative effect of the crude extract and the partitioned fractions on the diabetic induced alterations in serum lipid profile occurs in a significant (p<0.05) dosedependent manner. In conclusion, G. sylvestre extracts possess hypoglycaemic effects and attenuated diabetic induced dyslipidemia in rats

Previously, we have found that the addition of L-ascorbic acid to chitosan enhanced the reduction in body weight gain in guinea pigs fed a high-fat diet. We hypothesized that the addition of L-ascorbic acid to chitosan would accelerate the reduction of body weight in humans, similar to the animal model. Overweight subjects administered chitosan with or without L-ascorbic acid for 8 weeks, were assigned to three groups: Control group (N = 26, placebo, vehicle only), Chito group (N = 27, 3 g/day chitosan), and Chito-vita group (N = 27, 3 g/day chitosan plus 2 g/day L-ascorbic acid). The body weights and body mass index (BMI) of the Chito and Chito-vita groups decreased significantly (p < 0.05) compared to the Control group. The BMI of the Chito-vita group decreased significantly compared to the Chito group (Chito: -1.0 kg/m2 vs. Chito-vita: -1.6 kg/m2, p < 0.05). The results showed that the chitosan enhanced reduction of body weight and BMI was accentuated by the addition of L-ascorbic acid. The fat mass, percentage body fat, body circumference, and skinfold thickness in the Chito and Chito-vita groups decreased more than the Control group; however, these parameters were not significantly different between the three groups. Chitosan combined with L-ascorbic acid may be useful for controlling body weight.

The aim of the study was to determine the development of ramie plants (Boehmeria nivea L. Gaud) and the effect of using ramie leaves on feed on the body weight gain of Wonosobo Sheep (Dombos). Research on the development of ramie plants using survey methods in the area of ramie plant development in Wonosobo Regency. While the research on the use of ramie leaves for fattening was carried out in Butuh Village, Kalikajar District, Wonosobo Regency in 2018. 21 male Dombos were divided into 3 feed treatments with forage proportions of 70%, 50% and 30 ramie leaves respectively. %. The results showed that currently ramie plants were being developed in Wonosobo Regency by CV. Ramindo Berkah Persada Sejahtera in Gandok Village, Kalikajar District, Wonosobo Regency, Central Java. Until now the area of the crop has reached 13 ha. Of this area will produce ramie leaves 195,000 kg / year. If one sheep needs 4 kg of ramie / tail / day leaves, then the potential capacity of sheep is 135 heads / year, if the given one is 50% then the Jurnal Litbang Provinsi Jawa Tengah, Volume 16 202 Nomor 2 – Desember 2018potential capacity is 270 heads / year and if it is reduced again to 25% of ramie leaves then the potential capacity 440 heads / year. The use of ramie leaves as a feed for Wonosobo Sheep fattening can be given as much as 30% in fresh form.

The study was planned to evaluate the effect of exogenous fibrolytic enzymes (EFE) supplementation for 56 days @ 240 mg/kg total mixed ration (TMR) on digestibility of dry matter and nutrients in dairy cows. Six dry non-pregnant cows were assigned in each treatment with and without EFE. The digestibility trial of seven days was conducted after 49 days of feeding. Dry matter and nutrients intake of cows was not influenced by EFE. The supplementation of EFE had improved digestibility of dry matter, organic matter, crude fiber, neutral detergent fiber, cellulose (p less than 0.01), as well as digestibility of nitrogen-free extract and acid detergent fiber, was also higher (pless than 0.05). The body weight gain of cows was higher on the supplementation of EFE in TMR. The study concluded that feeding exogenous fibrolytic enzymes (240 mg/kg) supplemented TMR improved digestibility of dry matter and nutrients, which was reflected as higher body weight gain in dry non-pregnant Gir and crossbred dairy cows.

Abstract Objectives The objectives of this study were to determine the effect of 2’fucosyllactose (2’FL) and fat blends on growth, body composition and fatty acid profile of the liver and brain using the neonatal pig as a model for the human infant. Methods Pigs (3 d old) were randomly assigned to either: 1. control, 2. Palm Olein (PO) fat blend – Low 2'-FL, 3. PO – High 2'-FL, 4. High oleic acid (HO) – Low 2'-FL, 5. HO FB – High 2'-FL, 6. PO FB – GLA, or 7. kept with their sows. Pigs in groups 1 to 6 received 250 ml·kg−1·d−1 of formula in 5 equal meals for 15 d. On day 14 of the study, groups 1–6 received intraperitoneal E. coli LPS challenge at 100 µg·kg−1 weight. Results Body weight was greater for piglets fed by sows than those in the other groups (P &lt; 0.001). In addition, % fat and bone mineral content were higher in the sow-fed group while lean % was less sow-fed piglets (group 7) compared with those in the other groups (P &lt; 0.05). Only longissimus weight expressed as a % of body weight, was greater for group 7 compared with all other groups (P &lt; 0.001). Soleus, semitendinosus, brain, heart and spleen weights as a % of body weight were similar across all groups. However, liver weight as a % of body weight was greater in groups 1–6 (3.7%) compared with group 7 (2.8%; P &lt; 0.001). The proportion of brain 16:1 fatty acid was less (0.83%) for groups 1–6 than for group 7 pigs (1.08%; P &lt; 0.0001). The proportion of 20:3 N6 was greatest (0.66%) for group 3 compared with groups 1 and 4 (0.55%; P &lt; 0.05). In addition, the proportion of 20:5 N3 was greatest (0.12%) for group 3 compared with groups 1 and 7 (0.07%; P &lt; 0.05). The proportion of liver 16:1, 18:0, and 18:1 cis-11 fatty acids were greater for group 7 (2.3, 23, 2.2%) than groups 1–6 (0.2, 20, 1.2%; P &lt; 0.0001). Conversely, the contribution of 14:0, 18:1 cis-9, 18:3 N6 cis-6,9,12, and 22:6 N3 were greater for pigs in groups 1–6 (1.3, 0.6, and 14, 7.8%) compared with those in group 7 (0.5, 8.5, 0.2 and 3.5%; P &lt; 0.0001). Conclusions Our data suggest that feeding 2’fucosyllactose had no effect on the body weight gain and composition in neonatal pigs. Our data also suggest that dietary fatty acids have a greater effect on liver than on brain fatty acid composition. Funding Sources Funding for the work was provided by Perrigo Nutritionals, LLC.

ABSTRACT Cortisol implants in normal and diabetic rats reduced body weight, adiposity, insulin receptor concentration and both basal and insulin-stimulated rates of lipogenesis in isolated adipocytes, whilst insulin sensitivity was unchanged. In normal but not diabetic rats these changes were accompanied by increased serum glucose and insulin concentrations. In contrast, progesterone implants in normal and diabetic rats increased body weight gain, adiposity, insulin receptor concentration and both basal and insulin-stimulated rates of lipogenesis in adipose tissue, again without affecting insulin sensitivity. Progesterone did not affect serum insulin concentrations in normal or diabetic rats but accelerated the decline in serum glucose concentrations which occurred during an overnight fast in diabetic rats. The results suggest that (1) cortisol inhibits lipogenesis in adipose tissue without affecting insulin sensitivity, (2) cortisol reduces insulin binding in adipose tissue without a requirement for hyperinsulinaemia, which might itself indirectly lead to down-regulation of the insulin receptor, and (3) in diabetic rats progesterone stimulates lipogenesis in adipose tissue without any increase in food intake or serum insulin concentrations suggesting that progesterone may have a direct anabolic role in adipose tissue.

In order to decide the optimum time of grazing for camels during hot summer months, 10 growing camel calveswere divided into 2 equal groups. First group was sent for grazing during 10:00 h to 16:00 h daily and second groupallowed for grazing during thermo neutral period. The climatic variables were recorded daily (April 2012 to March2013). The average daily gain and total body weight gain in calves sent for grazing during relatively cool parts ofday (group 2) was significantly higher as compared to group 1 calves sent as per routine farm schedule. Theaverage intake of fodder and water from manger was higher in group 1 calves. The average DMI from manger forgroup 1 calves was higher as compared to group 2 calves. The comparative biometrics of camel calves in differentgrazing management practices revealed that body length, heart girth, height at wither, neck length were significantly(P&lt;0.01) higher in group 2 calves as compared to group 1 calves. After 180 days of experimentation, humpcircumference vertical and hind leg length were significantly (P&lt;0.05) increased in group 2 as compared to group1. Analysis of recorded data of climatic parameters revealed that average maximum temperature was higher duringJune 2012. The values of THI also were higher in monsoon and post monsoon months hence the practice of sendingcamel calves during relatively comfortable part of hot and hot humid months was successful in getting good growth.The relative humidity was significantly higher during morning as compared to evening period for all months. TheTHI was significantly lower during morning as compared to evening hours for all months in different climate forwhole year. Economic analysis reveals that the cost of feed per kg body weight gain was quite less in group 2 ascompared to group 1. So the practice of grazing of camel calves during cool hours of day remain profitable forfarmers by looking at the body weight gain and better body conformation in climate change condition.
