Carcass Composition and Cuts of Bulls and Steers Fed with Three Concentrate Levels in the Diets
Ivanor Nunes do Prado,Rodrigo Augusto Cortez Passetti,Dayane Cristina Rivaroli,Mariano Garcia Ornaghi,Kennyson Alves de Souza,Camila Barbosa Carvalho,Daniel Perotto,Jose Luiz Moletta 아세아·태평양축산학회 2015 Animal Bioscience Vol.28 No.9
In this paper, weight, carcass dressing, weights of the primary cuts, weights of the physical components of the primary cuts, and weights of the main commercial cuts of 66 Purunã animals, of which 33 were bulls and 33 were steers were evaluated. These animals, with an average age of 19 months at the beginning of the experiment, were finished in a feedlot system during 116 days, and were fed with diets containing three levels of concentrate (0.8%, 1.1%, and 1.4% of body weight). The concentrate was formulated with 25% soybean meal, 73% ground corn grain, 1% of a mineral mix, and 1% of limestone. The interaction between sexual groups and the concentrate level was not significant for any of the variables. Likewise, no effect of the concentrate level was detected on the same variable traits. The bulls demonstrated higher hot carcass weights (265.1 vs 221.7 kg) and a higher proportion of forequarter (38.4% vs 36.1%) however the steers presented with higher proportions of side (19.7% vs 18.5%) and hindquarter (44.2% vs 43.1%). The bulls produced higher yields of muscle in the three primary cuts, there by resulting in higher yields of edible portions of the carcass. The bulls also produced higher weights of tenderloin, knuckle, topside, flat, eye round, rump, and rump cover. The finishing of young bulls in feedlot is to be recommended, since the animals produce carcasses with higher amounts of edible meat and higher yields of commercial cuts, thus allowing for a better price for the carcass. Low concentrate level could be used due to the lower cost of production for farmers.

Profile of Professionals of the Brazilian Production Sector of Timber Housing
( Victor DE ARAUJO ),( Cesar POLANCO ),( Elen MORALES ),( Juliana CORTEZ-BARBOSA ),( Maristela GAVA ),( Jose GARCIA ) 한국목재공학회 2019 목재공학 Vol.47 No.5
On account of the lack of education of Brazilian worker, this paper analyzed the characteristics of those professionals working in the production sector of timber houses. A sectoral survey was carried out with respective entrepreneurs to investigate the available professionals (career and contract types), evaluate the demands of skilled workers, and indicate solutions to improve the quality of labor qualification. Similarly, over 65% of sampled producers presented both direct-hired and outsourced workforce. For such contract ways, Civil Engineers and Architects were the main careers. Carpenters, Civil Engineers and Architects experienced on timber were the main sectoral demands. Timber Engineers have good potentials of service for this sector. The creation of courses on timber products can emerge as a key alternative to train people.

Biological Effects of Hydrolyzed Quinoa Extract from Seeds of Chenopodium quinoa Willd.

An extract from seeds of Chenopodium quinoa Willd. (quinoa), termed hydrolyzed quinoa (HQ), was obtained by enzymatic hydrolysis from seeds of the quinoa variety BRS-Piabiru. Analysis of the physical and chemical properties of quinoa and HQ showed that the hydrolyzed extract is rich in essential amino acids, particularly those with branched chains (leucine, isoleucine, and valine). In addition, we evaluated the biological effects of HQ, particularly the toxicological potential. For this purpose, male Wistar rats were assigned randomly to four groups: (1) sedentary supplemented group, which received HQ (2,000 mg/kg); (2) sedentary control group, non-supplemented; (3) exercised supplemented group (i.e., rats subjected to aerobic physical exercise that received HQ [2,000 mg/kg]); and (4) exercised control group (i.e., rats subjected to aerobic physical exercise, non-supplemented). After 30 days, all groups were analyzed for levels of serum glucose, cholesterol, triacylglycerol, total protein, albumin, uric acid, and urea and activities of the enzymes alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase. Body weight gain, dietary intake, and lipid deposition were also analyzed. The results showed no hepatic and renal toxicity of HQ. Moreover, decreased food intake, body weight, fat deposition, and blood triacylglycerol level were observed in the supplemented groups (sedentary and exercised supplemented groups). These results suggest a potential use of HQ in human nutrition.
