Resumo: | Abstract: The objective of this dissertation was to evaluate dephytinizated defatted rice bran for feeding broilers under performance parameters, carcass yield, tibiae resistance and apparent digestibility of protein, calcium and phosphorus. We used 576 male Cobb one day old broiler chicks. The experimental design was completely randomized, with four treatments (basal diet - DB; basal diet with addition of 10% defatted rice bran - FAD; basal diet with addition of 10% defatted dephytinizated rice bran - FADD; basal diet with the addition of 10% defatted rice bran treated with phytase - FADFIT) with 6 replicates of 24 birds each. Growth performance of the lot was not significantly different (P>0.05) among different treatments, as well as carcass yield. The tibiae of birds fed diets with added FADD showed less resistance to breakage compared with those fed the DB (P<0.05). Apparent protein digestibility was higher in birds fed FADD (P<0.05) when compared to those receiving FAD. It can be concluded that the addition of 10% of FADD in the diet, does no damage and has benefits in the digestibility of the protein, allowing the incorporation of this ingredient in feed for broilers. |

Foram utilizados 576 pintos de corte machos, de um dia de idade, da linhagem Cobb. O delineamento experimental foi inteiramente casualizado, composto por 4 tratamentos (dieta basal DB; dieta basal com adição de 10% de farelo de arroz desengordurado FAD; dieta basal com adição de 10% de farelo de arroz desengordurado desfitinizado FADD; dieta basal com adição de 10% de farelo de arroz desengordurado tratado com fitase FADFIT) com 6 repetições de 24 aves cada. O desempenho zootécnico do lote não apresentou diferença significativa (P>0,05) entre os diferentes tratamentos, assim como o rendimento de carcaça. As tíbias das aves que receberam dietas com adição de FADD apresentaram menor resistência a quebra quando comparadas as alimentadas com DB (P<0,05). A digestibilidade aparente da proteína foi superior nas aves alimentadas com FADD (P<0,05) quando comparada as que receberam FAD. Podese concluir que a adição de 10% de FADD nas dietas, não causa prejuízos a criação e apresenta benefícios na digestibilidade da proteína, permitindo a incorporação deste ingrediente na alimentação de frangos de corte.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em ZootecniaUFSMBRZootecniaÁcido fíticoDesfitinizaçãoDigestibilidadeEnzima exógenaFitaseFitatoPhytic acidDephytinizatedDigestibility exogenous enzymePhytasePhytateCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAFarelo de arroz desengordurado desfitinizado na alimentação de frangos de corteDephytinizated defatted rice bran in the feed of broiler chickensinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisZanella, Irineohttp://lattes.cnpq.br/7498503120935080Vale, Marcos Martinez dohttp://lattes.cnpq.br/5028362636820102Trevizan, Lucianohttp://lattes.cnpq.br/2577641181184878http://lattes.cnpq.br/7718415666503849Karkow, Ana Kátia50040000000240050050050030013f75ea9-d10b-4af9-a38a-b2ef3169f400fba7076a-7b0e-4cbf-8eb8-ba4a3ab7afa6bb2837b2-eb7c-42aa-a62b-1874712a7fd06f139a3d-db80-48df-9d96-f049a4a6dbf4info:eu-repo/semantics/openAccessreponame:Repositório Institucional Manancial UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALKARKOW, ANA KATIA.pdfapplication/pdf5307942http://repositorio.ufsm.br/bitstream/1/10772/1/KARKOW%2c%20ANA%20KATIA.pdfe5d0c2bdeea96d5ca8791ef0b81d5752MD51TEXTKARKOW, ANA KATIA.pdf.txtKARKOW, ANA KATIA.pdf.txtExtracted texttext/plain85539http://repositorio.ufsm.br/bitstream/1/10772/2/KARKOW%2c%20ANA%20KATIA.pdf.txt8bff002c0d1794e2ede40bb9524c12c1MD52THUMBNAILKARKOW, ANA KATIA.pdf.jpgKARKOW, ANA KATIA.pdf.jpgIM Thumbnailimage/jpeg4934http://repositorio.ufsm.br/bitstream/1/10772/3/KARKOW%2c%20ANA%20KATIA.pdf.jpgb6b54d0486588fb29df5be546c15ecf8MD531/107722022-08-23 14:26:06.485oai:repositorio.ufsm.br:1/10772Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestouvidoria@ufsm.bropendoar:39132022-08-23T17:26:06Repositório Institucional Manancial UFSM - Universidade Federal de Santa Maria (UFSM)false |
