Resumo: | The study was carried out to evaluate the performance and carcass and meat quality of surgically castrated, entire male/immunocastrated pigs fed with diets containing different levels of amino acids and energy with or without ractopamine. Seventy two pigs (surgically castrated and entire male/immunocastrated pigs) with average initial weight of 20 kg were used. The animals were distributed in a completely randomized experimental design with four treatments (T1 - surgically castrated pigs fed control diet; T2 - entire male/immunocastrated pigs fed control diet; T3 - entire male/immunocastrated pigs fed control diet + 3% amino acids and energy and T4 - entire male/immunocastrated pigs fed control diet + 5% amino acids and energy), with six replications, and three animals as an experimental unit. The second dose of immunocastration vaccine occurred 28 days before slaughter, at this time 5 ppm of ractopamine was added to the diet of half of the experimental units for each treatment. Twenty four animals were slaughtered (one per experimental unit) selected by experimental unit s average weight. The entire male pigs had feed intake 11% lower (P<0.05) and feed conversion 16% better (P<0.05) compared to surgically castrated. Supplementation with 5% of amino acids and energy reduced (P<0.05) at 6.9% the feed intake and improved (P<0.05) at 3.0% the feed conversion of entire male pigs. Immunocastrated pigs supplemented with 5% of amino acids and energy and 5 ppm ractopamine gained daily 0.13 kg more weight (P<0.05) and feed conversion was 13% better (P<0.05) compared to immunocastrated male pigs fed control diet without ractopamine. The slaughter weight of immunocastrated pigs supplemented with 5% of amino acids and energy was 12% higher (P<0.05) than surgically castrated fed control diet without ractopamine. When don t supplemented with ractopamine, the immunocastrated pigs had carcass yield 5.4% lower (P<0.05) than surgically castrated. Immunocastrated pigs supplemented with 5% of amino acid and energy with ractopamine had higher (P<0.05) weight of the belly and rib and superior value (P<0.05) in color b* (yellow-blue) of meat at 24 hours. Supplementation with 5% of amino acids and energy reduces feed intake, improves feed conversion and slaughter, belly and ribs weight of immunocastrated pigs. |

Foram utilizados 72 suínos (machos castrados e inteiros/imunocastrados) com peso médio inicial de 20 kg, distribuídos em um delineamento experimental inteiramente casualizado com quatro tratamentos (T1 - suínos machos castrados alimentados com dieta controle; T2 - suínos machos inteiros/imunocastrados alimentados com dieta controle; T3 - suínos machos inteiros/imunocastrados alimentados com dieta controle + 3% aminoácidos e energia e T4 - suínos machos inteiros/imunocastrados alimentados com dieta controle + 5% aminoácidos e energia), seis repetições de três animais por unidade experimental. A segunda dose da vacina de imunocastração foi realizada 28 dias antes do abate. Neste período foram adicionados 5 ppm de ractopamina na dieta de metade das unidades experimentais de cada tratamento. Foram abatidos 24 animais (um/unidade experimental) selecionados pelo peso médio da unidade experimental. Os suínos machos inteiros apresentaram consumo de ração 11% inferior (P<0,05) e conversão alimentar 16% melhor (P<0,05) em relação aos machos castrados. A suplementação com 5% de aminoácidos e energia reduziu (P<0,05) em 6,9% o consumo diário de ração e melhorou (P<0,05) em 3,0% a conversão alimentar de suínos machos inteiros. Suínos machos imunocastrados suplementados com 5% de aminoácidos e energia e 5 ppm de ractopamina ganharam diariamente 0,13 kg de peso a mais (P<0,05) e apresentaram conversão alimentar 13% melhor (P<0,05) em relação aos machos imunocastrados alimentados com a dieta controle sem ractopamina. O peso de abate de suínos machos imunocastrados suplementados com 5% de aminoácidos e energia foi 12% superior (P<0,05) aos machos castrados alimentados com a dieta controle sem ractopamina. Quando não suplementados com ractopamina, os suínos machos imunocastrados apresentaram rendimento de carcaça fria em média 5,4% inferior (P<0,05) aos machos castrados. Suínos machos imunocastrados suplementados com 5% de aminoácidos e energia com ractopamina apresentaram barriga e costela mais (P<0,05) pesados e valor superior (P<0,05) da coloração b* (amarelo-azul) da carne às 24 horas. A suplementação com 5% de aminoácidos e energia reduz o consumo de ração, melhora a conversão alimentar e o peso de abate, de barriga e costela de suínos machos imunocastrados.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em ZootecniaUFSMBRZootecniaAminoácidosEnergiaRactopaminaSuinoculturaAmino acidsEnergyRactopamineSwine productionCNPQ::CIENCIAS AGRARIAS::ZOOTECNIADiferentes níveis nutricionais para suínos machos: desempenho animal e qualidade da carcaça e da carneDifferent nutritional levels to male pigs: animal performance and carcass and meat qualityinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisRadünz Neto, Joaohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4783033E5Zanella, Irineohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4788657E9Oliveira, Vladimir dehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4794884J4http://lattes.cnpq.br/9145277942901954Lanferdini, Eloiza500400000002400500300500300516bfa73-6d2b-4483-b052-34c2e517e7a94cfc5a95-8c0c-412d-871f-318a211bea7de90265df-3980-4f01-a256-8a201ba774daf78f22bd-de73-49ec-8b7d-03dc6cb66070info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALLANFERDINI, ELOIZA.pdfapplication/pdf765982http://repositorio.ufsm.br/bitstream/1/10782/1/LANFERDINI%2c%20ELOIZA.pdf49206be497e7150a517e3576c1d85243MD51TEXTLANFERDINI, ELOIZA.pdf.txtLANFERDINI, ELOIZA.pdf.txtExtracted texttext/plain139841http://repositorio.ufsm.br/bitstream/1/10782/2/LANFERDINI%2c%20ELOIZA.pdf.txt7a103f449946e889c5c8d7106274539dMD52THUMBNAILLANFERDINI, ELOIZA.pdf.jpgLANFERDINI, ELOIZA.pdf.jpgIM Thumbnailimage/jpeg4886http://repositorio.ufsm.br/bitstream/1/10782/3/LANFERDINI%2c%20ELOIZA.pdf.jpga4b5e32f75106bb62a3de914e39d748aMD531/107822017-07-25 12:07:31.518oai:repositorio.ufsm.br:1/10782Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132017-07-25T15:07:31Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
