Resumo: | The objectives were to determine the effects of restricted-feeding strategies on blood concentrations of hormones, metabolites, and minerals in Holstein × Zebu finishing steers. Twenty steers (body weight = 319 ± 16.2 kg; age = 19 ± 1 months) were randomly allotted in 4 groups of 5 steers, which were restricted to 85% ad libitum feed intake for either 0 (R0; n = 5), 28 (R28; n = 5), 42 (R42; n = 5) or 84 (R84; n = 5) days of an 84-d finishing period. Steers were individually housed and considered the experimental unit. Blood samples were collected on d 0, 21, 42, 63, and 84, and were assayed for insulin-like growth factor 1 (IGF-1), thyroid hormones (T3 and T4), albumin, creatinine, urea, total protein, glucose, triglycerides, calcium, and phosphorus. Steers had increasing IGF-1 concentrations until d 42 when restricted-fed. Steers fed R84 had the greatest IGF-1 concentrations on d 84. Urea concentrations were greatest in steers fed R0 and least in steers fed R28; steers fed R42 and R84 were intermediate and not different from one another. Concentrations of IGF-1, urea, albumin, and calcium, but not T3, T4, glucose, triglycerides, creatinine, total protein, and phosphorus were affected by restricted-feeding strategies in Holstein × Zebu finishing steers.Keywords: Crossbred Cattle; Mineral Balance; Restricted Intake |

Vinte machos Holandês × Zebu castrados (peso corporal inicial [PC] = 319 ± 16,2 kg; idade = 19 ± 1 meses) foram aleatoriamente distribuídos em 4 grupos de 5 animais, os quais receberam alimentação restrita a 85% do consumo ad libitum por 0 (R0; n=5), 28 (R28; n=5), 42 (R42; n=5) ou 84 (R84; n=5) dias. Os animais foram alojados individualmente e considerados como unidades experimentais. Amostras de sangue foram coletadas nos dias 0, 21, 42 e 84, e analizadas quanto às concentrações de fator de crescimento semelhante à insulina 1 (IGF-1), hormônios tireiodianos (T3 e T4), albumina, creatinina, ureia, proteína total, glicose, triglicerídeos, cálcio e fósforo. Animais que receberam alimentação restrita apresentaram aumento nas concentrações de IGF-1 até o dia 42 (P < 0,05). Animais R84 apresentaram as maiores (P < 0,05) concentrações de IGF-1 no dia 84. As concentrações de ureia foram maiores (P < 0,05) para os animais AL84 e menores (P < 0,05) para os animais R28; os animais R42 e R84 apresentaram valores intermediários e não diferentes (P > 0,05) entre si. As concentrações de IGF-1, ureia, albumina, e calcium, mas não as de T3, T4, glicose, triglicerídeos, creatinina, proteína total e fósforo, foram influencias pelas diferentes estratégias de alimentação restrita utilizadas em machos Holandês × Zebu castrados em terminação.Palavras-chave: Balanço Mineral; Bovinos Cruzados; Consumo Alimentar RestritoUniversidade Federal de Goiás2020-10-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/63329Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 21 (2020): Continuous publicationCiência Animal Brasileira / Brazilian Animal Science; v. 21 (2020): Publicação contínua1809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporenghttps://revistas.ufg.br/vet/article/view/63329/35584https://revistas.ufg.br/vet/article/view/63329/35585https://revistas.ufg.br/vet/article/view/63329/35586https://revistas.ufg.br/vet/article/view/63329/35587Copyright (c) 2020 Ciência Animal Brasileirainfo:eu-repo/semantics/openAccessAdriane de Sales Silva, FláviaDe Campos Valadares Filho, Sebastião Navajas Rennó, LucianaVeloso Trópia, Nathalia William Magalhães Souza, CaioMeneguelli Alhadas, HerlonGarcia Mafort, EricaLouise Felix, Tara2023-03-23T18:46:38Zoai:ojs.revistas.ufg.br:article/63329Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:26.422288Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
