... Soil organic carbon (SOC) plays a key role in sustaining pasture agroecosystem function and its rate of accumulation can be influenced by management practices including manure deposition and grazing intensity. This study was conducted to determine the impacts of 13-years of different pasture management practices on SOC content and aggregation. The field experiment was conducted in a watershed cons ...

Abstract:
... Invasive alien plants (IAPs) compromise the productive capability of a land parcel from both an economic and a biodiversity perspective. Given the magnitude of degradation and the benefits of landscape-scale restoration, a unified approach among stakeholders is required to upscale restoration efforts. Seeking such an approach, we compare the efficiencies of two restoration and land use models for ...
... It is well recognised that excessive soil erosion is a significant environmental issue for disturbed landscape systems. This is particularly the case for agriculture, where soil loss is not only a source of pollution but impacts soil fertility and sustainability. In recent years, improved pasture management, rotational grazing and holistic management practices have been employed and it is generall ...

Abstract:
... Forage intake is one of the most important indicators of health and productivity of ruminant livestock, such as sheep. Forage intake estimation can also make an important contribution to the design and implementation of rotational grazing systems. In this paper, sheep forage intake estimation models were developed based on acoustic analysis from data gathered by an audio recorder mounted on a shee ...

Abstract:
... The quality of the social environment should be studied as one of the welfare components of dairy herds. Licking and preference between cows are important socio-positive experiences in this context.The aims of this study were: 1) to describe the behaviours temporally associated with social licking in grazing dairy cows, 2) to measure the association of social licking with social hierarchy and gest ...

Abstract:
... Two ways of reducing the cost of replacements are increasing litter size and number of litters produced; thus, the total weight of lamb carcass output per ewe lifetime. The effects of ewe genotype on the performance of ewes lambing at 1 year and of their progeny to slaughter, and the effect of age at first joining (7 or 19 months) on BW at ~19 months and survival to joining at 19 months were evalu ...

Abstract:
... Livestock grazing can lead to reduced ground cover and altered composition of pastures through the loss of palatable forage species and reduced litter cover. This negatively impacts landscape function and ultimately livestock production. Grazing livestock for short periods with high animal density, followed by long rests to allow pasture recovery (short-duration grazing), could be a way to address ...

Abstract:
... The concentration of Co in the herbage of a large proportion of grassland farms in Ireland is lower than that required by sheep. The effects of supplementing ewes with Co, and method of supplementation, on ewe and offspring performance, were evaluated over 2 years. The ewes (359 in year 1, 241 in year 2), representing 3 genotypes, were allocated to one of 3 treatments. The treatments were: Control ...

Abstract:
... QUESTIONS: The impact of grazing on the phenology of alpine plants has not been deeply explored. In particular, how the phenology of all species in the alpine plant community is affected by grazing has seldom been monitored. STUDY SITE: Qinghai‐Tibetan Plateau of China. METHODS: A linear mixed model was used to explore the effect of grazing regimes (continuous grazing, grazing exclusion and rotati ...
... A comprehensive understanding of multipaddock, rotational grazing management on rangelands has been slow to develop, and the contribution of adaptive management (Briske et al. 2011) and sufficient scale (Teague and Barnes 2017) have been identified as key omissions. We designed an experiment to compare responses of vegetation and cattle in an adaptively managed, multipaddock, rotational system wit ...

Abstract:
... Rhipicephalus microplus is the most significant tick of livestock and its control is particularly challenging due to its resistance to commercial acaricides. Pasture rotation is considered a management strategy that could help control R. microplus, however, the literature only contemplates mathematical models and little is known about the effects of this practice in the field. The objective of thi ...

... In Nepal, the Tibetan argali Ovis ammon hodgsoni was documented from the Mustang and Humla districts until 2013. In 2016, we observed a young ram in the Dolpa district, providing the third locality record. We compiled historical data and our own observation data from 2013 to 2016 to discuss the present distribution of the Tibetan argali in Nepal. We suggest reassessing the National Red List to rec ...

Abstract:
... Adaptive multi-paddock (AMP) grazing is a form of rotational grazing in which small paddocks are grazed with high densities of livestock for short periods, with long recovery periods prior to regrazing. We compared the fluxes of greenhouse gases (GHGs), including carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O), from soils of AMP-grazed grasslands to paired neighboring non-AMP-grazed g ...

Organic dairy cows (n = 90) of Holstein and crossbred genetics were used to evaluate the effect of two pasture production systems (cool season perennial and warm season annual grass species) across two grazing seasons (May to October of 2014 and 2015) on milk production, milk components (fat, protein, MUN, SCS), body weight, body condition score (BCS), and activity and rumination (min/d). Cows wer ...

Abstract:
... In natural grasslands, effects of warming on net ecosystem CO2 exchange (NEE) may interact with grazing. Yet, the effects of these two main drivers of terrestrial carbon cycling are typically studied in isolation, limiting our understanding of how NEE would be affected under different global change scenarios. Here, we report results of a warming experiment using infrared heaters combined with summ ...

Abstract:
... To support irrigation efficiency improvement, it is essential to identify the major limitations to irrigation management. Thirty‐two dairy farmers in Canterbury, New Zealand, were interviewed in order to understand current irrigation strategies on pastoral farms, particularly in relation to grazing rotations and plant available water (PAW). A water balance model, IrriCalc, was used to estimate irr ...

In many countries, daily herbage accumulation on pasture declines towards zero during the winter period; thus, many pregnant ewes are housed and offered conserved forages supplemented with concentrate prior to parturition.

Abstract:
... Predator-prey interactions where livestock are killed by carnivores, are a serious global challenge. Conservation interventions to address this conflict are inadequately guided by ecological theory, and instead rely on pragmatic experiential decisions. I review four families of theoretical models that can accommodate essential features of this human-wildlife conflict, namely – prey-refuge, special ...

Abstract:
... Livestock ranching is one of the most important economic activities of the planet but is also associated with negative environmental impacts. Ranching can also exacerbate social inequality by displacing vulnerable rural populations from access to land and decisions over land use.

... With the proliferation of woody plant species in much of the world's grasslands, human has manipulated landscape fire to return their forage provisioning service. Yet other ecosystem services (e.g., carbon sequestration, biodiversity conservation, erosion control) in the post-managed areas compared to those previously available in the shrub-encroached area are largely unknown, including trade-offs ...
