Performance of Meadow Fescue Accessions under Management-Intensive Grazing
marker analysis suggests that it is also closely related to perennial ryegrass, Lolium perenne L. (Xu and Sleper, Meadow fescue (Festuca pratensis Huds.) is a pasture grass that 1994). It hybridizes readily with both perennial and Italhas been little used in North America since the introduction of its higher yielding relative, tall fescue (F. arundinacea Schreb.).

متن کاملAnimal Factors Condition Milk Performance and Quality of Grazing Dairy Cows
The base of this review is to consider the relevant role that animal factors (potential milk yield, body weight, body condition score, state of lactation, parity and fertility) play on milk performance (considering the energy balance and the rumen function across the full lactation curve of animals) and milk quality (milk protein content, milk fat content, milk lactose content, vitamins, minera...
متن کاملGrazing Management in Spring and Subsequent Dairy Cow Performance
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...
متن کاملGrazing and Plant Performance.
Grazing is more than just defoliation of plants. The impact of herbivory affects ecosystem structure and function, both above and below ground. Ultimately, effects of herbivory are expressed to varying degrees at many levels of the ecosystem. Herbivory has been shown to affect plant physiology, morphology, and genetics. Plants have evolved many ways to avoid or tolerate herbivory. Whether plant...
