Influences on Perceived Feasibility of Animal-Based Measures in a Producer-Driven Welfare Benchmarking System.

A voluntary, producer-driven welfare benchmarking system has been explored as a way of incentivising welfare improvement in pasture-based beef cattle and providing transparency and accountability to the industry. This study aimed to determine the acceptability and feasibility of measures for inclusion in a welfare benchmarking system and how this is influenced by respondents' attitudes and beliefs. A survey was disseminated online to Australian producers in July 2020.

Grazing management for soil carbon in Australia: A review.

The livestock industry accounts for a considerable proportion of agricultural greenhouse gas emissions, and in response, the Australian red meat industry has committed to an aspirational target of net-zero emissions by 2030. Increasing soil carbon storage in grazing lands has been identified as one method to help achieve this, while also potentially improving production and provision of other ecosystem services. This review examined the effects of grazing management on soil carbon and factors that drive soil carbon sequestration in Australia.

Enzyme pre-milling treatments improved milling performance of chickpeas by targeting mechanisms of seed coat and cotyledon adhesion with various effects on dhal quality.

Background: Dehulling and splitting are important elements of the milling process to produce dhal from pulses. However, grain that is difficult-to-mill because of tightly adhered seed coats or cotyledons that resist separation makes it difficult to achieve high quality dhal. Milling yields are reduced, energy inputs into the milling process are increased, and the resulting dhal can be of poorer quality, chipped or abraded.

Biochar lowers ammonia emission and improves nitrogen retention in poultry litter composting.

The poultry industry produces abundant quantities of nutrient-rich litter, much of which is composted before use as a soil amendment. However, a large proportion of nitrogen (N) in poultry litter is lost via volatilisation during composting, with negative environmental and economic consequences. This study examined the effect of incorporating biochar during composting of poultry litter on ammonia (NH) volatilisation and N retention.

Biochar increases nitrogen retention and lowers greenhouse gas emissions when added to composting poultry litter.

Biochar has intrinsic and nascent structural and sorption properties that may alter the physical and chemical properties of a composting mixture thus influencing the production of greenhouse gases [GHGs; nitrous oxide (NO) and methane (CH)]. In this study, contrasting biochars produced from greenwaste (GWB) or poultry litter (PLB) were incorporated into a composting mixture containing poultry litter and straw, and GHG emissions were measured in situ during composting using Fourier Transform Infrared Spectroscopy (FTIR). Emissions of NO from the biochar-amended composting mixtures decreased significantly (P<0.

Video-assisted thoracic surgery systematic mediastinal nodal dissection and stage migration: impact on clinical pathway.

Objectives: The aim of this study is to investigate the role of routine systematic mediastinal nodal dissection (SND) performed during video-assisted thoracic surgery (VATS) major pulmonary resections (VMPRs) as a staging strategy for non-small-cell lung cancer (NSCLC), compared with preoperative staging by conventional positron emission tomography (PET) and computed tomography (CT) imaging.

Methods: All patients suspected of having early lung cancer (T1-2, N0-1 and M0) were staged preoperatively by CT/PET. During VMPR, all lymph nodes on the right side at stations 2-4, 7, 8, 9, 10 and 11 and on the left stations 4-6, 7, 8, 9, 10, 11 and 3 when indicated were dissected en bloc.
