Resumo: | The aim of this study was to evaluate the influence of different sources of carbohydrates (corn, soybean hulls and wheat bran) on ingestive behavior of twenty four steers with initial average of age and weight of 20 months and 330 kg and Charolais or Nellore predominance. The time spent in feeding activities (214min./day) and total rumination (458min./day) weren t influenced by diet carbohydrate sources. The animals in the wheat bran treatment spent less time in total idling (678min.) in relation to the corn (768min./day) and soybean hulls treatment (774min./day). The neutral detergent fiber (NDF) intake was higher for the animals fed with soybean hulls and wheat bran (5.18 and 5.42 kg/day respectively) compared with those who received corn as a carbohydrate source (3.35kg/day), however the non-fibrous carbohydrates intake was higher for this source of carbohydrate (4.29kg/day), intermediate for wheat bran (2.53kg/day) and lower for those in soybean hulls treatment. The steers fed with soybean hulls presented less intake of digestible energy (27.62Mcal/day) in relation to the corn (35. 5 Mcal/day) and wheat bran (33. 25 Mcal/day) treatments. Rumination efficiency of NDF was higher for soybean hulls (11.92g/min.) and wheat bran (10.23g/min.) compared to corn (7.68g/min.). The chewing time per ruminal bolus was lower for soybean hulls (0.88min./bolus) compared to the diets containing corn (0.96min./bolus) and wheat bran (0.95min./bolus). The animals with Charolais predominance presented higher feeding periods (29.41min.) in relation to the steers with Nellore predominance (24.95min.). The sources of carbohydrates tested didn t influence the feeding and total rumination time of the animals. The animals with Nellore predominance remain less time in lying idling, present longer periods of feeding and spend more time in chewing per ruminal bolus. |

Os tempos despendidos com alimentação (214min./dia) e ruminação total (458min./dia) não foram influenciados pelas fontes de carboidratos. Os animais do tratamento farelo de trigo permaneceram menos tempo em ócio total (678min.) em relação ao milho (768min./dia) e a casca de soja (774min./dia). O consumo da fibra em detergente neutro (FDN) foi maior para os animais alimentados com casca de soja e farelo de trigo (5,18 e 5,42kg/dia respectivamente) comparado aos que receberam milho como fonte de carboidrato (3,35kg/dia), no entanto o consumo de carboidratos não-fibrosos foi superior para esta fonte de carboidrato (4,29kg/dia), intermediário para o farelo de trigo (2,53kg/dia) e inferior para aqueles do tratamento casca de soja. Os novilhos alimentados com casca de soja apresentaram menor consumo de energia digestível (27,62 Mcal/dia) em relação aos tratamentos milho (35,5 Mcal/dia) e farelo de trigo (33,25 Mcal/dia). A eficiência de ruminação FDN foi superior para a casca de soja (11,92g/min.) e farelo de trigo (10,23g/min.) em comparação ao milho (7,68g/min.). O tempo de mastigações por bolo ruminal foi menor para a casca de soja (0,88min./bolo) em comparação as dietas contendo milho (0,96min./bolo) e farelo de trigo (0,95min./bolo). Os animais de predominância Charolês apresentaram maiores períodos de alimentação (29,41min.) em relação aos novilhos de predominância Nelore (24,95min.). As fontes de carboidrato testadas não influenciam o tempo de alimentação e de ruminação total dos animais. Novilhos de predominância Nelore permanecem menos em ócio deitado, apresentam períodos de alimentação mais demorados e gastam mais tempo de mastigação por bolo ruminal.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em ZootecniaUFSMBRZootecniaCasca de sojaCharolêsFarelo de trigoMilhoNeloreÓcioSoybean hullsCharolaisWheat branOrnNelloreIdleCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAFontes de carboidrato no comportamento ingestivo de novilhos confinadosCarbohydrates sources on ingestive behavior of steersinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisAlves Filho, Dari CelestinoCV: http://lattes.cnpq.br/2140386505744337Brondani, Ivan Luizhttp://lattes.cnpq.br/5813089147720195Santos, Angélica Pereira doshttp://lattes.cnpq.br/7357564338601048http://lattes.cnpq.br/0276140236060780Silva, Viviane Santos da500400000002400500500500300e80896c6-107c-4173-83b3-2f62810c5f9ca761b3de-577e-4a2d-8b77-e4027f9274b4361c8d58-f791-48c8-9294-6373ef0cec39657e3f9a-c28a-4b47-8f69-eac3dd5e66fainfo:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALSILVA, VIVIANE SANTOS DA.pdfapplication/pdf4452033http://repositorio.ufsm.br/bitstream/1/10800/1/SILVA%2c%20VIVIANE%20SANTOS%20DA.pdf18e524867d3b28ebc50063a43e649884MD51TEXTSILVA, VIVIANE SANTOS DA.pdf.txtSILVA, VIVIANE SANTOS DA.pdf.txtExtracted texttext/plain119642http://repositorio.ufsm.br/bitstream/1/10800/2/SILVA%2c%20VIVIANE%20SANTOS%20DA.pdf.txta65b0b93aa3427fc7ccd10f0d284cd91MD52THUMBNAILSILVA, VIVIANE SANTOS DA.pdf.jpgSILVA, VIVIANE SANTOS DA.pdf.jpgIM Thumbnailimage/jpeg4607http://repositorio.ufsm.br/bitstream/1/10800/3/SILVA%2c%20VIVIANE%20SANTOS%20DA.pdf.jpg6eee95cde64e7a331dd8347e9ede0455MD531/108002021-09-23 11:07:50.444oai:repositorio.ufsm.br:1/10800Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132021-09-23T14:07:50Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
