Características produtivas de pastagens de milheto ou capim sudão submetidas ao pastejo contínuo de vacas para abate

Abstract: Objetivou-se avaliar os parâmetros produtivos das pastagens de milheto (Pennisetum glaucum (L.) R. BR) e capim sudão (Sorghum bicolor cv. sudanense) submetidas ao pastejo contínuo de vacas destinadas ao abate. O delineamento experimental foi o inteiramente casualizado com dois tratamentos e três períodos, sendo cinco repetições (área). Os parâmetros produtivos das pastagens foram similares na comparação entre os tratamentos (P<0,05). O ciclo vegetativo das pastagens não alteraram a massa de forragem (1.606,… Show more

“…, which is lower than those values reported by Pacheco et al (2014) in millet pastures (80.52 kg of DM ha ). The AR decreased as a function of the decrease in the photoperiod and beginning of floral differentiation of the forage sorghum as the pasture utilization cycle advanced (Table 5), going from an accumulation of 75.85 to 20.46 kg of DM ha −1 from the first to the third period, respectively.…”

“…The highest value of WGA was found in the second grazing period, with value of 141.18 kg ha ) in WGA when compared to the first 56 days of pasture utilization. Pacheco et al (2014) observed similar behavior in millet and Sudan grass pastures, who found a decreased WGA in the order of 47% at the end of pasture utilization period. Table 9 shows the variables related to body development of heifers during the experimental period.…”

“…Studies conducted with millet in the form of pasture showed satisfactory performance in animal feeding (Roman et al, 2008;Jochims et al, 2010;Pacheco et al, 2014). In these studies, the fresh matter was used for the determination of the mass of pasture.…”

“…Experiments using millet, in which fresh matter was evaluated, used variable plot sizes and number of replicates, such as plots of 6 m 2 (1.5 m wide and 4.0 m long), with five replicates (Pinho et al, 2013), plots of 12 m 2 (2.5 m wide and 4.8 m long) and four replicates (Priesnitz et al, 2011) and plots of 15 m 2 , with six replicates (Moreira et al, 2003), all of them arranged in a randomized block design. On the other hand, experiments using the fresh matter for the determination of mass of forage in millet pasture employed larger plot sizes, 1,350 m 2 , with two replicates (Jochims et al, 2010) and 13,000 m 2 , with five replicates (Pacheco et al, 2014) in a completely randomized experimental design.…”

“…Esses valores revelaram maior eficiência quantitativa em produção de massa, proteína, minerais e extrato etéreo da planta à altura de 50 cm. Apesar de os valores serem inferiores aos observados na literatura (13)(14)(15) , deve ser considerado o fato de a cultura ter sido avaliada na entressafra em condições de temperatura e precipitação restritivas.…”
