The objective of this work was to assess the effects of the sward structure of Italian ryegrass (Lolium multiflorum), during the first grazing cycle, on its morphological and bromatological characteristics throughout the growing season, and on the performance of dairy cows. The treatments consisted of two structures obtained as a function of canopy-light interception: high-light interception (HLI) and low-light interception (LLI), with different pre-grazing heights in the first grazing cycle. Pasture was managed under rotational grazing with a herbage allowance not below 30 kg dry matter (DM) per cow per day. Three grazing cycles, with a grazing interval of 30 days, were evaluated. Pre-grazing herbage mass was greater (2,240 vs. 1,656 kg ha-1 DM), but the...

ABSTRACT:  Ruminants vary their walking trajectory according to the positioning of the trees in integrated systems, which can determine the concentration of dung deposition at certain locations. The aim of this study was to map the distribution of feces and the behavior of dairy heifers in sunny and shaded areas. This experiment was carried out in Mato Grosso, Brazil, where the main grazing conditioner is shade due to the presence of trees in the pastures. Shading levels used were: full sunlight (control), moderate shade (338 trees ha−1) and intensive shade (714 trees ha−1) in randomized complete blocks. The experimental period was divided into three evaluation periods based on rainfall distribution: rainy period = December 2012; transition period = March...

Autores: Ribeiro Filho,Henrique Mendonça Nunes; Setelich,Elena Apezteguia; Crestani,Steben; Dias,Kamila Maciel; Mantovani,Carolina; Valenti,Joana.
The aim of this study was describe the relationship between grazing time and herbage intake and identify tools to grazing management of dairy cows grazing Italian ryegrass (Lolium multiflorum Lam.) on a rotational grazing method. Six dairy cows in mid-lactation period were allowed to graze paddocks during three grazing cycles. During each cycle cows grazed two paddocks with 9 days of occupation by paddock and an herbage allowance of 30kg DM cow-1 day-1. Measurements were made in the last 9 days of each period and during intervals between cycles cows grazed an adjacent area with a mixed of temperate species. It was compared three grazing cycles and cows eating similar herbage amount with different daily grazing time. Independently of herbage intake, daily...

Autores: Ribeiro Filho,Henrique Mendonça Nunes; Giacomet,Carlos Dionei; Dias,Kamila Maciel; Crestani,Steben; Setelich,Elena Apezteguia; Thaler Neto,André.
Neste trabalho, foi avaliado o efeito da suplementação com proteína de baixa degradabilidade ruminal (PNDR) para vacas leiteiras em pastos de azevém anual (Lolium multiflorum Lam.). Foram utilizadas 12 vacas da raça Holandesa no terço médio de lactação. Os tratamentos avaliados foram zero e 4,0kg vaca-1 dia-1 de uma mistura 60:40 de grão de milho + farelo de glúten de milho, em três períodos de avaliação de 15 dias. Os animais foram distribuídos em quatro lotes uniformes (dois por tratamento) e alocados em piquetes de azevém manejado no método rotativo, com uma oferta de 24kg de MS vaca-1 dia-1. A massa de forragem (2.325kg MS ha-1) e a altura (15,8cm) antes da entrada dos animais foram semelhantes nos piquetes dos animais suplementados e não...
