Resumo: The objective of this study was to measure the effect of supplementation with molasses blocks compared with conventional mineral supplementation (with specific formulations for the rainy and dry season) in 92 7-month-old Nellore heifers (Experiment 1) and 40 primiparous 31-month-old Nellore cows (Experiment 2) in Marandu grazing areas. The following measurements were obtained: weight, supplement intake, blood urea and glucose in heifers (Experiment 1), supplement intake, cow weight, body score, calf weight and ruminal temperature and drinking events in primiparous females (Experiment 2). The average molasses block intake was 242 g day-1 per heifer, with an average weight gain of 0.290 kg day-1; the heifers who consumed the molasses blocks were heavier during the rainy season (P < 0.05; Experiment 1). In Experiment 2, molasses block intake varied from 77 to 821 g day-1 per primiparous female, and the average intake in the control group was between 100 and 370 g day-1. The primiparous females given molasses blocks displayed lower weight loss due to calving (P < 0.05) and retained higher body scores at 150 days postpartum (P < 0.05). Ruminal temperature (P < 0.05) and drinking events (P < 0.05) were higher in primiparous Nellore females given molasses blocks. Overall, molasses blocks effectively increased Nellore female performance during the rainy season in Marandu grass pastures.

Também foram realizadas as seguintes medições: peso, consumo do suplemento, ureia e glicose em novilhas (Experimento 1) e consumo de suplemento, peso de vacas primíparas, condição corporal, peso de bezerros, temperatura ruminal e frequência da ingestão hídrica nas primíparas (Experimento 2). O consumo médio dos blocos de melaço, por novilha, foi de 242 g dia-1, com ganho de peso de 0,290 kg dia-1. As novilhas que consumiram os blocos contendo melaço tiveram maiores pesos durante a estação chuvosa (P < 0,05) (Experimento 1). No experimento 2, a ingestão de blocos de melaço variou de 77 a 821 g dia-1 por primípara, e a ingestão média no tratamento controle foi entre 100 e 370 g dia-1. As fêmeas primíparas tratadas com blocos de melaço apresentaram menor perda de peso devido ao parto (P < 0,05), e mantiveram escores corporais mais elevados aos 150 dias pós-parto (P < 0,05). A temperatura ruminal (P < 0,05) e a frequência do consumo de água (P < 0,05) foram maiores nas primíparas Nelore do tratamento com blocos de melaço. O uso de blocos de melaço incrementam o desempenho de fêmeas Nelore durante a estação chuvosa em pastagens de capim Marandu.UEL2019-07-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionsuplementação em pastagemapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3432910.5433/1679-0359.2019v40n5p1991Semina: Ciências Agrárias; Vol. 40 No. 5 (2019); 1991-2006Semina: Ciências Agrárias; v. 40 n. 5 (2019); 1991-20061679-03591676-546Xreponame:Semina.
