“…For the variable grazing time, there was a quadratic effect with maximum point of inclusion at 4.61% castor meal, and the value found herein for the maximum grazing time was 700 minutes, within the range reported by Euclides et al (2000), which claims that, in general, grazing time varies from 420 to 720 minutes a day and very close to that registered by Zanine et al (2007), who also worked with Brachiaria brizantha and verified an average of 649.2 grazing minutes per day. Variations in the grazing time can be attributed to the passage rate of the feed through the rumen and the consumption/ demand ratio (CARVALHO, 1997).…”

“…Although grazing time was higher (p < 0.05) in the ICLF system (Table 3), leisure activity was not different between the systems. Although the resting time spent is distributed throughout the day, heifers prefer doing it during the dawn and early morning (Zanine, Santos, Parente, Ferreira, & Cecon, 2007), which explains the peaks of resting times observed in the ICLF system at 04:00 and 06:00 ( Figure 5). Tree shading in ICLF allowed the heifers to rest according to the period of their preference, while in the ICL system, the animals concentrated this activity preferably at 09:00 when the THI reached the value of 83 ( Figure 5) and at 22:00, just after a rumination peak (Figure 4).…”

“…No sistema com amendoim forrageiro, o menor (P<0,05) tempo de ócio, verificado em dezembro, foi devido à maior necessidade de seleção da forragem, atribuída à composição do pasto com elevada participação de material morto e ao menor valor nutritivo do pasto na entrelinha (Tabelas 2 e 3). O tempo médio de ócio de 19,75% (3 h e 57 min) é inferior ao encontrado em estudo desenvolvido por Olivo et al (17) , que verificaram 5h e 8 min de ócio em 20 horas de observação, e aos encontrados por Zanine et al (23) , estudando vacas Holandês x Zebu no terço inicial de lactação em pastejo contínuo de Brachiaria decumbens ou Brachiaria brizantha, encontrando 4h e 47 min e 4h e 59 min para as respectivas pastagens. Essas comparações apontam que os animais demandaram mais tempo para selecionar sua dieta, implicando em menor tempo de ócio, justificado pela mistura forrageira que apresenta picos e ciclos diferenciados de produção.…”
