Resumo: The objective of this study was to evaluate, in rainy season, the effect of protein complementation during dry season on Nellore primiparous heifers. We used 39 primiparous heifers, with an average age of 24-36 months, reared on Brachiaria decumbens and Brachiaria Brizantha pasture, for 205 days. The animals were weighed every 28 days, after fasting for 12 hours. The experimental design was a split plot, the two treatments were distributed in two installments, the six periods in subplots and the animals were the replications. The following variables were analyzed: weight, hip height, body condition score, average daily weight gain and average monthly growth, presenting the respective values of 318.5 kg, 142 cm, 3.24, 0.580 kg and 2.55 cm respectively for previously supplemented animals, and 309.6 kg, 141 cm, 3.23, 0.584 and 2.29 kg cm for  non-supplemented animals. There were no significant differences between the two experimental groups. Pregnancy rate of supplemented animals was 57% and it did not differ from non-supplemented animals’ rate (45%). Calving rate was 100% for both groups. In the rainy season, after supplementation, heifers that did not receive supplementation during the dry period of the previous year had similar reproductive and weight performance as the supplemented ones.Keywords: beef cattle; dietary restriction; feedback; protein supplementation; reproduction.

Para isto, foram utilizadas 39 fêmeas bovinas entre 24-36 meses, em pastagens de Brachiaria brizantha e Brachiaria decumbens por 205 dias, pesadas a cada 28 dias, após jejum de 12 horas. O delineamento experimental foi em parcelas subdivididas, sendo os dois tratamentos distribuídos em duas parcelas, os seis períodos na sub parcela e os animais foram a repetição. As variáveis analisadas foram peso, altura de garupa, escore corporal, ganho em peso médio diário e crescimento médio mensal com valores de, respectivamente, 318,5 Kg, 142 cm, 3,24, 0,580 Kg e 2,55 cm para os animais previamente complementados e 309,6 Kg, 141 cm, 3,23, 0,584 Kg e 2,29 cm para os animais não complementados, não apresentando diferenças entre os dois grupos experimentais. A taxa de prenhez dos animais complementados foi de 57% e não diferiu dos não complementados (45%). A taxa de parição foi de 100% nos dois grupos experimentais. No período chuvoso após a complementação, as novilhas que não receberam complementação prévia no período seco do ano apresentaram desempenho ponderal e reprodutivo semelhante ao das complementadas.Palavras-chave: bovinos de corte; complementação proteica; realimentação; reprodução; restrição alimentar. Universidade Federal de Goiás2015-07-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/2416010.1590/cab.v16i3.24160Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 16 No. 3 (2015); 331-342Ciência Animal Brasileira / Brazilian Animal Science; v. 16 n. 3 (2015); 331-3421809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/24160/18823https://revistas.ufg.br/vet/article/view/24160/18824Nogueira, Ana Paula CarneiroAlvarenga, Paula Batista deFerreira, Isabel CristinaRios, Maisa PaschoalSilva, Cecilia Rodriguesinfo:eu-repo/semantics/openAccess2015-07-31T20:01:58Zoai:ojs.revistas.ufg.br:article/24160Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:59.260303Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
