Morphogenesis in guinea grass pastures under rotational grazing strategies

Revista Brasileira de Zootecnia, 2012
This study was conducted in order to evaluate the morphogenetic and structural characteristics of guinea grass cv. Mombasa under three post-grazing heights (intense - 30 cm, lenient - 50 cm and variable - 50 in spring-summer and 30 cm in autumn-winter ...

Twenty-five-centimeter pre-grazing canopy height in palisade grass and forage peanut

Scientia Agricola, 2021
: Short-term grazing behavior variables are sensitive to the canopy structure and have an impact on daily forage intake. This study evaluated the effect of pre- and post-grazing canopy heights on the forage harvesting process at a patch scale in a ...

Effect of pre-grazing herbage mass and post-grazing sward height on herbage production and intake and performance of suckler-bred steers within a weanling-to-beef production system

The Journal of Agricultural Science, 2023
AbstractThe current study investigated the effects of pre-grazing herbage mass (PGHM, 1500 or 2500 kg dry matter (DM)/ha) and post-grazing sward height (PGSH, 4 or 6 cm) on herbage production and its nutritive value and DM intake, grazing behaviour and growth of Charolais steers (n = 96; 12 months of age; 396 ± 19.0 kg) during a 222-day grazing season,

A grazing height target to minimize tiller stem elongation rate in annual ryegrass swards

Ciência Rural, 2016
: Italian ryegrass (Lolium multiflorum Lam) is one of the most cultivated temperate annual forage crop around the world. Despite that, there is little information about the process of stem elongation during its vegetative growth.

How do centipedes and millipedes respond to grazing intensity in an integrated crop-livestock system with soybean-pasture succession? [PDF]

Revista Brasileira de Ciência do Solo
Centipedes and millipedes promote important functions in the ecosystem. However, land use intensification in agricultural areas can reduce the abundance and diversity of these organisms.

Effect of Season and Nitrogen Fertilization on the Agronomic Traits and Efficiency of Piatã Grass in Brazilian Savanna

Agriculture, 2020
The aim of the present study was to evaluate the agronomic traits in the pre- and post-grazing and the nitrogen use efficiency of Piatã grass that was subjected to nitrogen fertilization throughout the seasons of the year. The experiment was performed in

Decomposition of cattle feces from Pennisetum purpureum pastures managed under different post-grazing stubble heights

Tropical Grasslands - Forrajes Tropicales, 2014
Pasture management can affect cattle diets. Post-grazing stubble height is a structural characteristic intrinsically linked to forage quantity and quality. Stubble height also indicates forage utilization rate, and as a result, affects nutrient return pathways (excreta or litter) and, ultimately, nutrient cycling.

Soil intake of lactating dairy cows in intensive strip grazing systems

Animal, 2012
Involuntary soil intake by cows on pasture can be a potential route of entry for pollutants into the food chain. Therefore, it appears necessary to know and quantify factors affecting soil intake in order to ensure the food safety in outside rearing ...

Effect of Grazing Intensity and Frequency on Forage Accumulation and Agronomic Characteristics of Tropical Mixed Pastures

Grasses
This study evaluated combinations of defoliation frequencies and intensities to identify grazing strategies that optimize forage accumulation and morphological composition in mixed pastures of Marandu palisadegrass (Urochloa brizantha cv.
