Lipid profile of subcutaneous fat, growth performance, and carcass characterist...
Marçal,Danilo Alves; Kiefer,Charles; Alencar,Stephan Alexander da Silva; Farias,Taynah Vieira Aguiar; Santos,Luana Cristiane dos; Viana,Luiz HenriqueABSTRACT: This study identified the effects of dietary supplementation with ractopamine, chromium picolinate, chromium yeast, or an energetic feed restriction on the growth performance and lipid profile of subcutaneous fat, in late finishing gilts. Twenty genetically similar gilts with initial body weight of 105.35 ± 4.77 kg and a final body weight of 131.37 ± 5.58 kg were distributed in a completely randomized...
Ractopamine concentration on the lipid profile of swine fat and meat
Alencar,Stephan Alexander da Silva; Kiefer,Charles; Nascimento,Karina Márcia Ribeiro de Souza; Viana,Luiz Henrique; Gonçalves,Liliane Maria PianoABSTRACT: This study was conducted to evaluate the effect of ractopamine concentrations on swine fat and meat lipid profiles. Ninety finishing barrows, initially weighing 71.9±4.4kg, were distributed in a randomized block design in three ractopamine concentrations (0, 10 and 20ppm) with fifteen replicates of two animals in each. Gas chromatography was used to analyze the lipid profiles of backfat and meat. The ...
Net energy levels on the lipid profile of pork
Alencar,Stephan Alexander da Silva; Kiefer,Charles; Nascimento,Karina Márcia Ribeiro de Souza; Viana,Luiz Henrique; Gonçalves,Liliane Maria PianoABSTRACT: This study was conducted to evaluate the effects of net energy levels on the lipid profile of adipose tissue and muscle of swines. A total of 90 animals, with initial weight of 71.94±4.43kg, were used, and distributed in a randomized block design in five net energy levels (2,300, 2,425, 2,550, 2,675, and 2,800Kcal kg-1 feed), with nine replicates and two animals per experimental unit. Lipid profiles o...
Perfil lipídico da polpa e amêndoa da guarirova
Nozaki,Vanessa Taís; Munhoz,Cláudia Leite; Guimarães,Rita de Cássia Avellaneda; Hiane,Priscila Aiko; Andreu,Maxwell Parrela; Viana,Luiz HenriqueOs óleos de frutos estão sendo estudados por seu potencial na indústria de alimentos e também para aumento do consumo de ácidos graxos monos e poli-insaturados. Este estudo objetivou determinar as constantes físico-químicas, composição centesimal, identificar e quantificar os principais ácidos graxos presentes na fração lipídica da polpa e da amêndoa dos frutos de guarirova, espécie Syagrus oleracea (Mart.) Bec...
Adubação nitrogenada em cobertura na cultura da mamona em plantio direto
Silva,Tiago Roque Benetoli da; Leite,Valdemir Espinosa; Silva,Antonio Renan Berchol da; Viana,Luiz HenriqueO objetivo deste trabalho foi avaliar a aplicação de nitrogênio em cobertura na cultura da mamona (Ricinus communis L.), em Campo Grande, MS. As doses de N foram 0, 30, 60 e 120 kg ha-1. A semeadura foi realizada em 27 de janeiro de 2006. O espaçamento entre linhas utilizado foi de 0,9 m e 0,45 m entre plantas. Foram realizadas as seguintes avaliações: altura e diâmetro de caule das plantas, número de cachos e ...
Processo químico industrial de extração de óleo vegetal: um experimento de quím...
Vianna,José Francisco; Pires,Dario Xavier; Viana,Luiz HenriqueIn this study we describe an experimental procedure based on a chemical industrial process of soya-bean oil extraction applied in general chemistry for undergraduate students. The experiment was planned according to the Science, Technology and Society (STS) approach to teach basic chemical concepts and provide grounding in the management of environmental care. The use of real life chemistry problems seems to sa...
