Resumo: | The objective of the present study was to evaluate the effect of the use of different fat sources on feedlot steers finishing diets, on their performance, economic evaluation, carcass and meat characteristics. Twenty steers, with average initial age and weight of 20 months and 260 kg, were used. The offered roughage was corn silage and the tested concentrates were: TCB basic concentrate; TFAI basic concentrate + integral rice bran + rice oil; TM3 - basic concentrate + 3% of fatty acids calcium salts and TM6 basic concentrate + 6% of fatty acids calcium salts. The roughage:concentrate used relation was of 66:34. The dry matter, crude protein, digestible energy, neutral and acid detergent fibers intakes were similar between treatments, as well as average weight gain and final weight (P>.05). However, difference was observed for ether extract daily intake, being the higher value for the animals that consumed 6% of fatty acid calcium salts (.77 kg), intermediary value for the ones that consumed 3% of fatty acid calcium salts and the ones that consumed integral rice bran plus rice oil (.51 kg) and lower value for the ones that consumed basic concentrate (.25 kg). Concentrate and total diet costs, as well as the weight gain necessary to cover feed costs was higher for animals that consumed 6% of fatty acid calcium salts, however gross and net incomes were similar. The animals that consumed 6% of fatty acid calcium salts presented higher subcutaneous fat thickness (5.21 mm) and carcass total fat content (27.9%). Meat characteristics from steers that consumed integral rice bran and oil or fatty acid calcium salts were similar from the ones that didn t consume fat. |

Foram utilizados 20 novilhos, com idade e peso vivo médios iniciais de 20 meses e 260 kg. O volumoso oferecido foi a silagem de milho e os concentrados testadas foram: TCB concentrado base; TFAI concentrado base + farelo de arroz integral e óleo de arroz; TM3 concentrado base + 3% de sais de cálcio de ácidos graxos e TM6 concentrado base + 6% de sais de cálcio de ácidos graxos. A relação volumoso:concentrado utilizada foi de 66:34. Os consumos de matéria seca, proteína bruta, energia digestível, fibras em detergente neutro e ácido foram similares entre os tratamentos, bem como o ganho de peso médio diário e peso final (P>0,05). Entretanto, houve diferença no consumo de extrato etéreo diário, sendo maior para os animais que consumiram 6% de sais de ácidos graxos (0,77 kg), intermediário para aqueles que consumiram 3% de sais de ácidos graxos e para aqueles que consumiram farelo de arroz integral e óleo (0,51 kg) e inferior para os que consumiram concentrado base (0,25 kg). Os custos com concentrado e da dieta total, bem como o ganho de peso necessário para compensar os custos com a alimentação foram maiores para os animais que consumiram 6% de sais de cálcio de ácidos graxos, entretanto as receitas brutas e líquidas foram semelhantes. Os animais que consumiram 6% de sais de cálcio de ácidos graxos apresentaram maiores espessura de gordura subcutânea (5,21mm) e conteúdo total de gordura na carcaça (27,9%). As características das carnes dos novilhos que consumiram farelo de arroz integral e óleo de arroz ou sais de ácidos graxos foram semelhantes aos que não ingeriram gordura.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em ZootecniaUFSMBRZootecniaCarcaçaCarneDesempenhoFarelo de arroz integralSais de cálcio de ácidos graxosCarcassFatty acid calcium saltsIntegral rice branMeatPerformanceCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAFontes de gordura na dieta de novilhos terminados em confinamentoFat sources in feedlot steers finishing dietsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisRestle, Joãohttp://lattes.cnpq.br/7559938697233077Brondani, Ivan Luizhttp://lattes.cnpq.br/5813089147720195Menezes, Luis Fernando Glasenapp dehttp://lattes.cnpq.br/2949435070245794http://lattes.cnpq.br/3921011577858890Metz, Patrícia Alessandra Meneguzzi500400000002400500300500300068c9bf5-5104-4c69-a422-32a546b01895580f40fd-5e52-47fd-8502-a6d61e2a5528361c8d58-f791-48c8-9294-6373ef0cec396fd29e3c-cfe5-4441-8527-386adf187c33info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALMETZ, PATRICIA ALESSANDRA MENEGUZZI.pdfapplication/pdf1248511http://repositorio.ufsm.br/bitstream/1/10734/1/METZ%2c%20PATRICIA%20ALESSANDRA%20MENEGUZZI.pdf9187e12eb994502d3606b479c8399eb0MD51TEXTMETZ, PATRICIA ALESSANDRA MENEGUZZI.pdf.txtMETZ, PATRICIA ALESSANDRA MENEGUZZI.pdf.txtExtracted texttext/plain204279http://repositorio.ufsm.br/bitstream/1/10734/2/METZ%2c%20PATRICIA%20ALESSANDRA%20MENEGUZZI.pdf.txt4dc46019ffcc10d770806911ea0527d5MD52THUMBNAILMETZ, PATRICIA ALESSANDRA MENEGUZZI.pdf.jpgMETZ, PATRICIA ALESSANDRA MENEGUZZI.pdf.jpgIM Thumbnailimage/jpeg4934http://repositorio.ufsm.br/bitstream/1/10734/3/METZ%2c%20PATRICIA%20ALESSANDRA%20MENEGUZZI.pdf.jpg974c634fe5f814956419b3e73fd1b59bMD531/107342022-01-06 09:20:25.206oai:repositorio.ufsm.br:1/10734Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-01-06T12:20:25Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
