BACKGROUND: Extracts rich in phenolic compounds have an important role in antioxidant and antimicrobial effects, and pistachio green hull extract is rich in polyphenolic compounds. OBJECTIVES: The aim of this study was to evaluate the effect of green peel of Kalleqouchi and Fandoghi pistachio extract on performance, relative weight of carcass components, blood indices and intestinal microbial population of broiler chickens challenged with Staphylococcus aureus. METHODS: A total 168 one-day-old broiler chicks were randomly divided into six treatments, four replications and seven chicks. Experimental treatments included unchallenged groups (negative control) and chickens challenged with Staphylococcus aureus and fed 0, 200 and 400 mg / kg of aqueous extract of Kalleqouchi pistachio and 200 and 400 mg/ kg of pistachio Fandoghi green extract. All infected chicks were inoculated with oral solution containing 3 x 109 CFU of Staphylococcus aureus. Performance characteristics, immunity, blood indices and microbial population of the intestine were determined. RESULTS: The aqueous extract of green pistachio inhibited the growth of Staphylococcus but the ethanolic extract inhibited the growth of lactobacilli. Growth performance of chicks was not affected by the experimental treatments except at day 24, when aqueous extract of 200 mg / kg led to higher body weight gain as compared to control (0.049). Kalleqouchi extract at 400 mg/kg level increased abdominal fat (P = 0.0005) and had no effect on relative weight of other carcass components. The 400 mg/kg Fandoghi green extract and 200 mg/kg kalleqouchi extract increased enzyme activity of alanine aminotransferase activity and decreased the concentration of blood total protein (P <0.01). The pistachios extracts at all levels increased total antibody titer compared to control (P <0.02). Pistachio extract reduced total bacterial population of jejunal area compared to negative control (P = 0.008). CONCLUSIONS: Application of aqueous extract of pistachio extract improves immune response, decreases blood lipids and intestinal microbial population of broiler chickens challenged with Staphylococcus aureus.

BACKGROUND: Heat stress declines the performance through physiologic changes of the poultry. OBJECTIVES: This experiment was conducted to evaluate the effects of different levels of L-carnitine on performance, carcass characteristics and some blood parameters of broiler chickens fed with high fat diets under heat stress. METHODS: Two hundred one-day-old broiler chicks (Ross 308) were used in a completely randomized design by four treatments and five replicates (pen) 10 birds in each replicate. The chickens of experimental treatments were fed with basal diet (control group) and the diets plus the different levels of 100, 200 and 300 mg/kg L-carnitine. The experimental diets were used during the finisher period (day 24 to 42 of age) and under heat stress (32±1ºC as cyclic from 9.00 AM to 5.00 PM). RESULTS: The results showed that the chicks fed with the highest L-carnitine had the higher weight gain during the finisher period as compared to control and the lower L-carnitine fed chicks (p<0.05). Furthermore, the feed conversion ratio of birds fed with the medium and high L-carnitine levels (100 and 300 mg) was lower than that of control birds (p<0.05). In orthogonal contrasts, L-carnitine supplementation caused the improvement in weight gain and feed conversion ratio during both the finisher and whole experimental periods (p<0.05). The consumption of highest L-carnitine decreased the abdominal fat as compared to control (p<0.05). In orthogonal contrasts, L-carnitine consumption caused the higher glucose and lower abdominal fat in comparison to control (p<0.05). CONLUSIONS: Totally, the results of recent experiment show that consumption of 300 mg/kg L-carnitine improves the performance of broiler chickens through the increase in dietary fatty acids and energy.

OBJECTIVE To determine effects of hydrocortisone administration on serum leptin and adiponectin concentrations, abdominal fat distribution, and mRNA expression of leptin and adiponectin in abdominal adipose tissue of dogs. ANIMALS 12 healthy dogs. PROCEDURES Dogs received hydrocortisone (8.5 mg/kg; n = 6) or a placebo (6) orally every 12 hours for 90 days. Serum leptin and adiponectin concentrations were measured with a canine-specific ELISA on the day before (day 0; baseline) and during (days 1, 3, 7, 30, 60, and 90) administration. On days 0, 30, 60, and 90, abdominal fat mass was quantified with CT, and mRNA expression of leptin and adiponectin in abdominal fat was analyzed by use of a PCR assay. RESULTS Hydrocortisone administration resulted in an increase in visceral fat mass on days 60 and 90, compared with the mass at baseline. Visceral fat mass at the level of L3 increased during hydrocortisone administration. Serum leptin concentration began to increase on day 1 and was significantly higher than the baseline concentration on days 30 and 60. Serum adiponectin concentration on days 30, 60, and 90 was significantly lower than the baseline concentration. Leptin and adiponectin mRNA expression in abdominal fat was greater on day 30, compared with expression at baseline, but lower on days 60 and 90, compared with expression on day 30. Serum leptin concentration and visceral fat mass were correlated. CONCLUSIONS AND CLINICAL RELEVANCE Hydrocortisone administration affected abdominal fat distribution and serum leptin and adiponectin concentrations through dysregulation of leptin and adiponectin expression.

OBJECTIVE To evaluate the effect of exposure to a balanced electrolyte solution (BES), or equine abdominal fat on the knot-holding capacity (KHC), relative knot security (RKS), weight, and volume of forwarder knots versus surgeon's knots. SAMPLE 315 knots tied and tested in vitro. PROCEDURES United States Pharmacopeia size-3 polyglactin 910 suture exposed to air (dry [control]), equine abdominal fat (fat-exposed), or BES (BES-exposed) was used to tie forwarder knots with 2, 3, and 4 throws and surgeon's knots with 5, 6, 7, and 8 throws. A universal materials testing machine was used to test the tensile strength of suture and knots to failure, and the KHC, RKS, weight, and volume of knots were determined. RESULTS Forwarder knots had significantly higher KHC and RKS and lower volume, compared with surgeons’ knots. Forwarder knots tied with fat-exposed suture had greater weight, but not volume, than did forwarder knots tied with dry or BES-exposed suture with the same number of throws. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that forwarder knots were superior to surgeon's knots when configured as start knots intended for continuous lines of suture. Exposure to media did not negatively affect mechanical or physical properties of forwarder knots and may improve specific biomechanical functions, including KHC and RKS.

Objective: To determine the effects of hypothyroidism on insulin sensitivity, glucose tolerance, and concentrations of hormones counter-regulatory to insulin in dogs. Animals: 8 anestrous mixed-breed bitches with experimentally induced hypothyroidism and 8 euthyroid control dogs. Procedures: The insulin-modified frequently sampled IV glucose tolerance test and minimal model analysis were used to determine basal plasma insulin and glucose concentrations, acute insulin response to glucose, insulin sensitivity, glucose effectiveness, and disposition index. Growth hormone response was assessed by stimulation and suppression tests. Additionally, basal serum growth hormone (GH) and insulin-like growth factor-1 (IGF-1) concentrations and urine cortisol-to-creatinine concentration ratios were measured and dual energy x-ray absorptiometry was performed to evaluate body composition. Results: Insulin sensitivity was lower in the hypothyroid group than in the euthyroid group, whereas acute insulin response to glucose was higher. Glucose effectiveness and disposition index were not different between groups. Basal serum GH and IGF-1 concentrations as well as abdominal fat content were high in hypothyroid dogs, but urine cortisol-to-creatinine concentration ratios were unchanged. Conclusions and Clinical Relevance: Hypothyroidism appeared to negatively affect glucose homeostasis by inducing insulin resistance, but overall glucose tolerance was maintained by increased insulin secretion in hypothyroid dogs. Possible factors affecting insulin sensitivity are high serum GH and IGF-1 concentrations and an increase in abdominal fat. In dogs with diseases involving impaired insulin secretion such as diabetes mellitus, concurrent hypothyroidism can have important clinical implications.

Objective: Various disease complications are a risk of overweight or obesity, so losing weight can reduce the risk of diseases caused by obesity. Binahong leaf ethanol extract (Anredera cordifolia) is a weight-loss herbal preparation. Aim: This study aims to analyze whether A. cordifolia extract is effective in losing weight by affecting the mechanism of adipogenesis in an animal obesity model. Materials and Methods: Animals were grouped into six groups as follows: the normal diet (K1), the negative control group (K2), the positive control group with Orlistat at a dose of 20 mg/kg BW (K3), an ethanol extract of A. cordifolia leaves at doses of 50 mg/kg BW (P1), 100 mg/kg BW group (P2), and 150 mg/kg BW (P3). All rats were fed a diet that consisted of high fat for eight weeks, except K1. Afterward, the treatments were given based on group distribution. Then, the rats were treated based on their groups for 4 weeks, and the high-fat diet was still given during the treatment for the control groups (K2). Anthropometric examinations such as body weight, length, and the circumference of the abdomen were measured. Metabolic parameters, including blood glucose, cholesterol levels, triglyceride levels, and abdominal fat weight, were measured using molecular parameters that measured PI3K levels and Extracellular signal-regulated kinase (ERK) in abdominal fat tissue samples using the ELISA method. Results: ERK levels of abdominal fat were lowered in the treatment group using the extract of A. cordifolia (50 mg/kg BW (P1) and 100 mg/kg BW (P2)) compared to the control group that was given a high-fat diet without treatment. The control group, which was fed a high-fat diet without treatment, had an average ERK level of 10.17 ± 2.98 ng/ml, P1 (50 mg/kg BW). Furthermore, when ethanol extracts were used as opposed to the control group, which received a high-fat diet without treatment, there was an increase in phosphoinositide three-kinase (PI3K) levels (K2). The control group received 9.35 ± 2.87 ng/ml, the treatment group received 100 mg/kg BW (P2) 9.48 ± 1.54 ng/ml, and the treatment group received 150 mg/kg BW (P3) 7.87 ± 1.79 ng/ml. The weight of fat in the abdomen differed between the groups that received a high-fat diet without treatment (K2) and those that received a high-fat diet with treatment (P1, P2, P3; p &lt; 0.05). Conclusion: Anredera cordifolia extract possesses anti-obesity activities by decreasing ERK and increasing PI3K levels, as well as reducing abdominal fat weight.

Broilers are chickens with high meat production. The productivity of broiler is seen from the percentage of carcass and abdominal fat. This study aims to determine the effect of giving fermented coconut pulp (Cocos nucifera L) on the percentage of carcass and abdominal fat of broilers. This study used a completely randomized design experimental method (CRD) consisting of 6 treatments and 6 replications so that the total observations were 36 units of observation. Each treatment had P1: 100% commercial feed without fermented coconut dregs, P2: 90% commercial feed + 10% fermented coconut dregs, P3: 80% commercial feed + 20% fermented coconut dregs, P4: 70% commercial feed + 30 % fermented coconut dregs, P5: 60% commercial feed + 40% fermented coconut dregs, P6 : 50% commercial feed + 50% fermented coconut dregs. The data were analyzed using the analysis of variance which was preceded by the battle test, followed by the Tukey test using the SPSS program. The analysis of variance showed significantly different results (P0.05) on the percentage of carcass and abdominal fat of the broiler. Tukey's follow-up test on the carcass showed a significant difference (P0.05) and there was no significant difference in fat (P0.05). It can be concluded that the supplementary feed of fermented coconut pulp can be used 40% as additional feed to increase the carcass percentage but not reduce the broiler abdominal fat percentage.
