Resumo: | The objective of this experiment was to verify the effect of nutritional management that alternates periods of energy/protein restriction and refeeding of grazing crossbred heifers during their prepuberty on the hormonal profile and blood parameters. The study was conducted at Princesa do Mateiro farm in Ribeirão do Largo, in the southwest region of the state of Bahia. Twenty crossbred heifers 5/8 Dairy Guzerat x 3/8 Dutch with an average age of 12 months and average body weight of 187 ± 13.74 kg were used at the beginning of the experiment. It lasted 238 days, 14 out of them were for the animals’ adaptation. The animals were kept in rotational grazing of Brachiariabrizantha cv. Marandú pastures and randomly assigned to two treatments: Control (T100) = animals receiving concentrate supplement to supply 100% of the nutrients requirement to gain 750 g day-1 of live weight and Compensatory Nutrition (CN). The animals of the CN treatment alternated periods of Restriction (T80) = receiving concentrate supplement to meet 80% of the demand for nutrients of the (T100) and periods of Refeeding (T120) = getting concentrate supplement to supply 120% of the nutrient requirements of the (T100 The final plasma concentrations of IGF-I, glucose and urea were higher (P<0.05) in the animals undergoing compensatory nutrition (CN) treatment. The insulin, cholesterol, progesterone and protein levels of the animals from Control and CN nutritional systems did not changed (P>0.05). There were positive correlations (P<0.05) between IGF-I, insulin, glucose and cholesterol, and a negative correlation (P<0.05) between IGF-I and urea. There were also positive correlation (P<0.05) between insulin and glucose and positive correlation (P<0.05) between glucose and cholesterol. There was a negative correlation (P<0.05) of the urea with cholesterol, progesterone and protein. Progesterone also showed a positive correlation (P<0.05) with the protein. |

O estudo foi conduzido na fazenda Princesa do Mateiro, em Ribeirão do Largo, na região Sudoeste do estado da Bahia. Foram utilizadas 20 novilhas mestiças 5/8 Guzerá Leiteiro x 3/8 Holandês, com idade média de 12 meses e peso corporal médio de 187 ± 13,74 kg, ao início do experimento. Teve duração de 238 dias, sendo 14 destinados à adaptação dos animais. Os animais foram mantidos em pastejo sob lotação rotacionada em pastos de Brachiaria brizantha cv. Marandú e aleatoriamente alocados em dois sistemas nutricionais: Controle (T100) = animais recebendo suplemento concentrado para suprir 100% da exigência de nutrientes para ganho de 750 g dia-1 de peso vivo e Nutrição Compensatória (NC). Os animais do sistema nutricional NC alternaram períodos de Restrição (T80) = recebendo suplemento concentrado para suprir 80% da exigência de nutrientes do (T100) e Realimentação (T120) = recebendo suplemento concentrado para suprir 120% das exigências de nutrientes do (T100). As concentrações plasmáticas finais de IGF-I, glicose e uréia foram superiores (P<0,05) nos animais submetidos à Nutrição Compensatória (NC). Os níveis de insulina, colesterol, progesterona e proteína não sofreram variações (P>0,05) entre os animais dos sistema nutricionais Controle e NC. Houve correlações positivas (P<0,05) entre o IGF-I, insulina, glicose e colesterol e correlação negativa (P<0,05) entre IGF-I e uréia. Houve correlação positiva (P<0,05) da insulina com a glicose. Ocorreu correlação positiva (P<0,05) da glicose com o colesterol. Houve correlação negativa (P<0,05) da uréia com o colesterol, progesterona e proteína. A progesterona também apresentou correlação positiva (P<0,05) com a proteína.UEL2015-06-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campoapplication/pdfimage/jpegapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1580310.5433/1679-0359.2015v36n3p1481Semina: Ciências Agrárias; Vol. 36 No. 3 (2015); 1481-1494Semina: Ciências Agrárias; v. 36 n. 3 (2015); 1481-14941679-03591676-546Xreponame:Semina.
