Abstract: a trial was conducted to evaluate the effect of reduced cp, amino acid-supplemented diets on performance of castrated males swines on high environmental temperature (32oc). a total of sixty crossbred piglets (landrace x large white) averaging initial weight of 15.2 kg was allotted to completely randomized experimental design with five treatments (18, 17, 16, 15, and 14% of cp), six replications and two animals per experimental unit. the experimental diets were fed to swine ad libitum until the end of the experiment, when the animals averaged 29.9 kg. the average temperature in the room was maintained in 32.3oc, with relative humidity of 75.9%, corresponding a black globe-humidity index (bghi) of 82.6. the reduced cp level, amino acid-supplemented-based diets did not affect the evaluated parameters (feed intake, weight gain and feed:gain ratio). no treatment effect on digestible lysine and energy intakes was observed. gradual reduction on daily nitrogen intake was observed. decreasing dietary cp levels affected only fat deposition rate. the highest values of relative and absolute weights of liver and stomach and the relative weight of kidneys were observed in the animals fed diets with the highest dietary cp level. it was concluded that the dietary cp level can be reduced from 18 to 14% for castrated piglets from 15 to 30 kg on high environmental temperature, with no effect on performance, since diets are supplemented with the essential amino acids.

Abstract: Background High plasma uric acid (UA) is a prerequisite for gout and is also associated with the metabolic syndrome and its components and consequently risk factors for cardiovascular diseases. Hence, the management of UA serum concentrations would be essential for the treatment and/or prevention of human diseases and, to that end, it is necessary to know what the main factors that control the uricemia increase. The aim of this study was to evaluate the main factors associated with higher uricemia values analyzing diet, body composition and biochemical markers. Methods 415 both gender individuals aged 21 to 82 years who participated in a lifestyle modification project were studied. Anthropometric evaluation consisted of weight and height measurements with later BMI estimation. Waist circumference was also measured. The muscle mass (Muscle Mass Index – MMI) and fat percentage were measured by bioimpedance. Dietary intake was estimated by 24-hour recalls with later quantification of the servings on the Brazilian food pyramid and the Healthy Eating Index. Uric acid, glucose, triglycerides (TG), total cholesterol, urea, creatinine, gamma-GT, albumin and calcium and HDL-c were quantified in serum by the dry-chemistry method. LDL-c was estimated by the Friedewald equation and ultrasensitive C-reactive protein (CRP) by the immunochemiluminiscence method. Statistical analysis was performed by the SAS software package, version 9.1. Linear regression (odds ratio) was performed with a 95% confidence interval (CI) in order to observe the odds ratio for presenting UA above the last quartile (♂UA > 6.5 mg/dL and ♀ UA > 5 mg/dL). The level of significance adopted was lower than 5%. Results Individuals with BMI ≥ 25 kg/m2 OR = 2.28(1.13-4.6) and lower MMI OR = 13.4 (5.21-34.56) showed greater chances of high UA levels even after all adjustments (gender, age, CRP, gamma-gt, LDL, creatinine, urea, albumin, HDL-c, TG, arterial hypertension and glucose). As regards biochemical markers, higher triglycerides OR = 2.76 (1.55-4.90), US-CRP OR = 2.77 (1.07-7.21) and urea OR = 2.53 (1.19-5.41) were associated with greater chances of high UA (adjusted for gender, age, BMI, waist circumference, MMI, glomerular filtration rate, and MS). No association was found between diet and UA. Conclusions The main factors associated with UA increase were altered BMI (overweight and obesity), muscle hypotrophy (MMI), higher levels of urea, triglycerides, and CRP. No dietary components were found among uricemia predictors.
