The objective of this study was to assess the effects of restricting access time to pasture and time of grazing allocation on grazing behaviour, daily dry matter intake (DMI), rumen fermentation, milk production and composition in dairy cows. Twenty-one autumncalving Holstein cows were assigned to one of the following 3 treatments: providing access to a daily strip of pasture for either 8 h bet...

Two levels of grazing intensity were unposed on pasture durtng a spring-time pre-treatment period in two years at Massey University’s Dary Cattle Research Urut. The two grazing intensws were lax (L), 2000-2500 kg DMlha residual herbage mass (RHM) and intense (I) 1000-1500 kg DM/ha RHM. imposed for 2 grazmg rotations. Durmg this period, net herbage accumulation (NHA) on the L wards was approxima...

Pasture micro-nutrient concentrations are often deficient for herbage productivity and the health of livestock. The aim this study was to investigate soil content effects on yield three pasture systems North Wyke Farm Platform (NWFP): high-sugar grass + legume mix minus nitrogen (N) fertilizer (blue/HSG L); permanent plus N (green/P N); (red/HSG N). locations with high total had a greater slope...

The time at pasture of dairy cows is often restricted in the context of extending the grazing season in autumn or at the end of winter. The objective of our study was to evaluate the effects of a restriction of time at pasture on milk production, herbage intake and feeding behaviour in dairy cows according to feeding regime. The four treatments consisted of 4 h or 8 h of time at pasture per day...
