Many wild weeds are used in Mexico as fodder. Due to their economic value, this investigation was undertaken to determine the chemical composition of 14 species. The mineral, crude protein, fiber, and total phenolic content, as well as the antioxidant activity, was determined. There was a significant variation in the mineral content among the 14 weeds, which all had calcium and potassium as the predominant elements. According to the results, some of the weeds might represent possible mineral deficiency sources, making the supplementation of certain minerals advisable. Although five of the species contained a low concentration of magnesium, the overall mineral ratios of the forage weeds were at safe levels, preventing grazing animals suffering from grass tetany, in contrast to the excessive calcium : phosphorus ratios that can affect their normal growth and bone development.The crude fiber and protein content in most of the weeds fell into the recommended range for the maintenance of cattle.The phenolic content of the studied weed extracts was higher than that reported for several Mediterranean forage species. These phenolic profiles correlate well with the radical scavenging activities of the extracts.

“…Another possibility is replacement of sown grasses by native plants. Native plants generally show lower nutritive values than improved forage cultivars, but they survive better than forage species after nutrient loss due to leaching (Nashiki et al 2005). A potential application limitation of this study is weak statistical evidence of the model due to the small number of sampling size in the abandoned pastures.…”

Plant diversity, productivity and nutritive value change following abandonment of public pastures in Japan

2013

View full text Add to dashboard Cite

We describe changes in plant diversity and productivity after the abandonment of public pastures in Japan. We surveyed the plant community and collected plant and soil samples from 22 pastures, including five pastures that had been abandoned up to 13 years earlier. Chemical analysis revealed forage nutritive values and soil nutrient levels. Overall, plant diversity did not change over time, but productivity and forage nutritive values both decreased significantly after pasture abandonment. These changes can be explained by (i) lower soil nitrate–nitrogen contents due to leaching and (ii) the replacement of sown grasses by native species. Our results suggest that it will become more difficult to restore pasture for grazing as the duration of abandonment increases and that reintroduction of livestock grazing in the abandoned pastures without re‐sowing exotic grasses could contribute to biodiversity conservation and maintaining productivity and nutritive values.

“…Annual weeds often are highly palatable to grazing ruminants (Marten and Anderson, 1975) and can have high nutritive value (Moyer and Hironaka, 1993;Nashiki et al, 2005). Small-bodied grazers, such as sheep and goats, are well-suited for integration into wheat production in the NGP as they are easily transported and confined, are common in the region, and consume a broad range of crop residues (Marten and Anderson, 1975).…”

Integrating Sheep Grazing into Cereal‐Based Crop Rotations: Spring Wheat Yields and Weed Communities

et al. 2015

Crop diversification and integration of livestock into cropping systems may improve the economic and environmental sustainability of agricultural systems. However, few studies have examined the integration of these practices in the semiarid areas of the Northern Great Plains (NGP). A 3-yr experiment was conducted near Bozeman, MT, to compare the effects of crop rotation diversity and weed management practices imposed during fallow periods [sheep (Ovis aries) grazing, reduced tillage, and conventional tillage] on spring wheat (Triticum aestivum L.) yields and weed pressure. Management treatments were applied to replicated whole plots, within which the split-plots received crop rotation treatments [continuous spring wheat (CSW) and a 3-yr rotation of annual forage, fallow, and spring wheat, where each phase was present in each year]. In the initial 2 yr, the realized rotational treatments were wheat-fallow and CSW. In the final year, wheat was grown following all phases of the diversified rotation. Yields were similar among management treatments within the wheat-fallow and CSW rotations. Weed pressure was generally low but perennial weeds were more abundant in grazing-managed, wheat-fallow systems. The integration of livestock into the annual hay crop-fallow-spring wheat rotation was associated with a nearly 30-fold increase in weed pressure and a yield reduction of 51.2% compared to conventional management. The results suggest that although targeted sheep grazing is a viable alternative to conventional fallow management in CSW and wheat-fallow rotations, successful integration of livestock in diversified cropping systems requires more effective weed management practices.
