Resumo: | This study aimed to evaluate the effect of different inclusion levels of black wattle tannin extract on nutrient intake, performance, carcass traits and ingestive behavior of feedlot finished lambs. Forty lambs, male, not castrated, weaned at 50 days old and from a cross between the Texel and Ile de France breeds were used. The diet consisted of roughage, which is corn silage, and concentrate, composed of disintegrated corn, soybean meal, calcitic limestone and common salt. The treatments consisted of five levels of inclusion of tannin extract in the diet (% of total DM in the diet), as follows: 0 (control), 1, 2, 3 and 4%. Intake of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), total carbohydrates (CHT), non-structural carbohydrates (NEC) and digestible nutrients totals (NDT) in the different ways in which they were expressed, were influenced in a quadratic way by the increase in the inclusion of tannin extract in the diets. The average daily weight gain (ADG) was influenced in a quadratic way, being at the maximum point of 0.303kg, with a level of 1.6% of tannin extract. The time spent in feeding activities, rumination, total chewing time and the time the animals remained idle were not influenced (P>0.05) by the treatment. Other activities (in minutes/day and in % of time in the 24 hours) were influenced in a quadratic way (P≤0.05). The highest concentration of feeding activities occurred around the period of supplying food to the animals (8-12 and 16-20 hours), while the highest concentration of rumination activities occurred between 00:00 and 8:00 in the morning. The number of times and time spent feeding and ruminating and the number of times the lambs drank water were not influenced (P>0.05). The use of 1.6% of black wattle tannin extract in the total DM of the diet of feedlot lambs receiving corn silage and concentrate in a 45:55 ratio is recommended to obtain better weight gain and carcass characteristics with satisfactory quality standard. The inclusion of black wattle tannin extract up to the level of 4% of the total DM of the diet does not significantly change the characteristics of the ingestive behavior of the animals. |

Foram utilizados 40 cordeiros, machos, não castrados, desmamados com 50 dias de idade e provenientes de cruzamento entre as raças Texel e Ile de France. A dieta foi composta por volumoso, sendo este a silagem de milho, e por concentrado, composto de milho desintegrado, farelo de soja, calcário calcítico e sal comum. Os tratamentos foram constituídos por cinco níveis de inclusão de extrato de tanino na dieta (% da MS total da dieta), sendo: 0 (controle), 1, 2, 3 e 4%. Os consumos de matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), extrato etéreo (EE), fibra em detergente neutro (FDN), carboidratos totais (CHT), carboidratos não estruturais (CNE) e nutrientes digestíveis totais (NDT) nas diversas formas em que foram expressos, foram influenciados de forma quadrática pelo aumento de inclusão de extrato de tanino nas dietas. O ganho de peso médio diário (GMD) foi influenciado de forma quadrática, sendo no ponto máximo de 0,303kg, com nível de 1,6% de extrato de tanino. Os tempos despendidos em atividades de alimentação, ruminação, o tempo de mastigação total e o tempo em que os animais permaneceram em ócio não foram influenciados (P>0,05) pelo tratamento. Já outras atividades (em minutos/dia e em % do tempo nas 24 horas), foi influenciada de forma quadrática (P≤0,05). A maior concentração das atividades de alimentação ocorreu em torno do período de fornecimento de alimento aos animais (8-12 e 16-20 horas), já a maior concentração das atividades de ruminação ocorreu entre as 00horas e as 8 horas da manhã. O número de vezes e o tempo despendido em alimentação e ruminação e o número de vezes que os cordeiros beberam água não foram influenciados (P>0,05). A utilização de 1,6% de extrato de tanino de acácia negra na MS total da dieta de cordeiros confinados recebendo silagem de milho e concentrado na proporção de 45:55, é recomendada para se obter melhor ganho de peso e características de carcaça com satisfatório padrão de qualidade. A inclusão de extrato de tanino de acácia negra até o nível de 4% da MS total da dieta não altera significativamente as características de comportamento ingestivo dos animais.Universidade Federal de Santa MariaBrasilZootecniaUFSMPrograma de Pós-Graduação em ZootecniaCentro de Ciências RuraisCarvalho, Sérgiohttp://lattes.cnpq.br/9114677690912835Venturini, Rafael SanchesBrutti, Danielle DiasOliveira, Mariana Dalla Favera Almeida de2023-06-12T12:45:57Z2023-06-12T12:45:57Z2023-04-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://repositorio.ufsm.br/handle/1/29358porAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSM2023-06-12T12:45:57Zoai:repositorio.ufsm.br:1/29358Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2023-06-12T12:45:57Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
