Efficiency of the use of ryegrass by heifers in response to the receival of supplement
Acta Scientiarum: Animal Sciences, 2017 The intensity and frequency of defoliation of ryegrass (Lolium multiflorum Lam.) by beef heifers exclusively grazing or receiving corn grain or extruded commercial product with fat as supplement were evaluated.

Frequencies and intensities of defoliation in Aruana guineagrass swards: morphogenetic and structural characteristics [PDF]
Revista Brasileira de Zootecnia, 2012 The objective of this study was to evaluate the morphogenetic and structural characteristics of Aruana guineagrass pastures (Panicum maximum cv. Aruana) subjected to rotational stocking by sheep. The treatments corresponded to grazing when swards reached 95 or 98% of interception of incident light (LI) until post-grazing heights of 10 and 15cm and were

Biomass flows and defoliation pattern of ryegrass grazed by supplemented heifers
Semina: Ciências Agrárias, 2017 To strategically define the best stocking rate management strategy for ryegrass, it is important to know the growth process of forage plants in detail. The study was conducted to analyze the leaf biomass flows and the defoliation intensity and frequency ...

Increased Defoliation Frequency Depletes Remobilization of Nitrogen for Leaf Growth in Grasses [PDF]
Annals of Botany, 1997 Plants ofLolium perenneandFestuca rubrawere grown in sand culture receiving all nutrients as a complete nutrient solution containing 1.5 mMNH4NO3, and subjected to one of three defoliation treatments: undefoliated, defoliated on one occasion, or defoliated weekly.15N labelling was used to determine the rate of N uptake, allowing the amount of N ...

EFFECT OF DATE AND FREQUENCY OF DEFOLIATION ON YIELD AND QUALITY OF ALFALFA [PDF]
Canadian Journal of Plant Science, 1961 In two experiments established in 1950 and 1953, Rhizoma and Grimm alfalfa, each in a simple mixture with timothy, were subjected to seven cutting schedules in the first 2 harvest years. In the third year all plots were cut on tune 15 to determine the effect of the differential defoliation in the preceding years.
