Resumo: This paper aimed to evaluate the supplements formulated from different sources of protein during the rainy season over the productive performance of beef heifers during breeding. In order to evaluate productive performance, 20 Holstein x Zebu crossbred heifers, with average body weight of 234 kg and approximate age of 14 months, were divided into five paddocks of B. decumbens Stapf of 2.5 ha each, in a completely randomized design with five treatments and four repetitions. The supplements were based on soybean meal (FS); cottonseed meal (FA) 38% crude protein (CP) (FA 38); corn gluten meal 60% CP (GM) and wheat bran + urea (FTU); and a treatment witness, composed of mineral mix (MM) only. The daily amount of supplement was established for providing about 180 g of CP day-1; that is, 0.450, 0.550, 0.350 and 0.450 kg animal-1 day-1, respectivelly, for the treatments with FS, FA38, GM and FTU. The animals were weighted every 28 days and rotated among the paddocks every 7 days. The ones which were submitted to the FTU treatment showed higher average daily gains (ADG) (p < 0.10) than those which received a MM treatment (0.839 X 0.666 kg day-1). The 500 g supply of supplement containing urea, FTU and minerals for heifers during breeding is recommended when intending to get moderate weight gain - around 850 g day-1.

Para avaliar o desempenho produtivo, 20 novilhas mestiças Holandês x Zebu e aneloradas, com peso corporal médio de 234 kg e idade aproximada de 14 meses, foram distribuídas em cinco piquetes de B. decumbens Stapf de 2,5 ha cada, em delineamento inteiramente casualizado, com cinco tratamentos e quatro repetições. Os suplementos foram à base de farelo de soja (FS), farelo de algodão 38% PB (FA38), farelo de glúten de milho 60% PB (GM) e farelo de trigo + ureia (FT), além de um tratamento-testemunha, constituído apenas de mistura mineral (MM). A quantidade diária de suplemento foi fixada para fornecer aproximadamente 180 g de PB dia-1, sendo 0,450; 0,550; 0,350 e 0,450 kg animal-1 dia-1, respectivamente, para os tratamentos FS, FA38, GM e FT. Os animais foram pesados a cada 28 dias e rotacionados entre os piquetes a cada sete dias. Os animais submetidos ao tratamento FT apresentaram ganhos médios diários (GMD) superiores (p < 0,10) àqueles recebendo o tratamento MM (0,839 X 0,666 kg dia-1). Recomenda-se o fornecimento de 500 g de suplemento que contém ureia, farelo de trigo e minerais para novilhas em recria, quando se deseja obter ganhos de peso moderados, em torno de 850 g dia-1.Editora da Universidade Estadual de Maringá2009-03-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpesquisa de campo; análise laboratorialapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/137210.4025/actascianimsci.v30i4.1372Acta Scientiarum.
