“…In the studies of Holschuch (2018) and Almeida (2018), the proportion of leaves and leaf area index (LAI) during post-grazing of Mulato II grass were higher for lenient defoliation (160 g kg −1 of leaves and LAI of 1.3) compared with pastures managed by severe defoliation (110 g kg −1 of leaves and LAI of 0.7), suggesting that this management (pre-grazing height of 25 cm and post-grazing height of 15 to 20 cm) is the most adequate for Mulato II pastures.…”

“…Milk production and ingestive behavior of cows grazing on Marandu and Mulato II pastures... Demski et al 2 Mulato II grass has shown good results of forage production, with an accumulation rate ranging from 70 to 100 kg dry matter (DM) of forage/day (Pequeno et al, 2015;Silva et al, 2016ab;Holschuch, 2018;Almeida, 2018). Pequeno et al (2015) highlighted the greater residual leaf mass of Mulato II compared with Marandu, even during the dry season, which increases its regrowth rate, demonstrating the potential use of this grass in rotational grazing systems.…”

The objective of this study was to evaluate milk production and ingestive behavior of Holstein cows and the structural characteristics of Mulato II, a hybrid Brachiaria grass CIAT 36087 (B. ruziziensis × B. decumbens × B. brizantha), and Marandu (Brachiaria brizantha cv. Marandu) pastures under rotational stocking. The experiment was conducted from December 2011 to April 2012 after 10 months of adaptation to the grazing management objectives (25 cm pre-grazing height and 15-20 cm post-grazing height). An area of 4 ha was divided into 28 paddocks: 14 with Mulato II pasture and 14 with Marandu pasture. The treatments consisted of the two grasses and a completely randomized design of the grazing variables with six repetitions each (paddock of evaluation) was used. For the animal variables, a randomized matched pairs design of 20 Holstein cows forming 10 blocks of two animals with similar production each was used. The forage mass or accumulation rate did not differ between grasses. Mulato II pastures had a higher tiller population density (822 tillers m −2 ) and crude protein content (143.5 g kg −1 ) than Marandu pastures (636 tillers m −2 and 130.3 g kg −1 crude protein). Cows kept on Mulato II exhibited shorter nighttime grazing activity (234 and 246 min in summer and autumn, respectively) than animals kept on Marandu (273 and 394 min, respectively). The average milk yield during the experimental period was higher for Mulato II (15.3 kg cow −1 day −1 ) compared with Marandu (14.3 kg cow −1 day −1 ). Both grasses have potential to be used in milk production systems for the grazing management objectives evaluated.
