This work reviews two mechanical separation technologies (screw press and decanting centrifuge) which could be used in the dairy, beef, pig and anaerobic digestion sectors in nutrient-vulnerable zones in order to improve ...
The UK dairy herd is predominantly of the Holstein-Friesian (HF) breed, with a major
emphasis placed on milk yield. Subsequently, following years of continued single-trait
selection, the beef production potential of dairy ...
This meeting/workshop has been organized by the United Nations Economic Commission for Europe (UNECE) in collaboration with the organizers of the 2019 International Congress of Meat Science and Technology ...
The beef industry is organized around di erent stakeholders, each with their own
expectations, sometimes antagonistic. This article first outlines these di ering perspectives. Then,
various optimization models that might ...

Anaerobic digestion provides renewable energy through waste valorisation, but the digestate by-product is
underutilised and presents a risk to water quality. Mechanical separation partitions phosphorous into the solid
fraction ...
Lying is a highly motivated behaviour in dairy cows. The level of comfort provided by the lying surface not only
affects lying time, but can also affect several other aspects of welfare. We used a crossover design to ...
Land, as a factor of production, has a vital role within the agricultural sector compared
with other sectors. However, in recent years, land mobility has become a significant issue around
the world with increased ...
Despite the important roles of Sustainable Agricultural Practices (SAPs) in improving productivity,
welfare, and food security of farming households, the adoption rates of SAPs have been perceived to be
generally low, ...
Issues relating to food availability, accessibility/afordability, and food utilization remain
paramount among diferent stakeholders such as policymakers and academics. Using data
from 250 maize farming households in ...
The efficiency with which dairy cows convert dietary nitrogen (N) to milk N is generally low (typically 25%). As a result, much of the N consumed is excreted in manure, from which N can be lost to the environment. Therefore ...
Improving nitrogen use efficiency (NUE) at both the individual cow and the herd level has become a key target in dairy production systems, for both environmental and economic reasons. Cost-effective and large-scale phenotyping ...
Both blood- and milk-based biomarkers have been analysed for decades in research settings, although often only in one herd, and without focus on the variation in the biomarkers that are specifically related to herd or diet. ...
Homeorhetic mechanisms assist dairy cows in the transition from pregnancy to lactation. Less successful cows develop severe negative energy balance (NEB), placing them at risk of metabolic and infectious diseases and reduced ...
Allowing dairy cattle to access pasture can promote natural behaviour and improve their health. However, the psychological benefits are poorly understood. We compared a cognitive indicator of emotion in cattle either with ...

ntegration of cover crops into arable rotations over winter results in difficulty in determining the nitrogen (N) requirement for the following commercial crop. The region of Northern Ireland (NI) has had no previous field ...
Background A number of European countries currently conduct mandatory farm- level benchmarking for
antimicrobial usage (AMU). This review describes the systems used, with emphasis on metric type and practical
implicati ...
A three-period change-over design study using 24 mid-lactation multiparous Holstein-Friesian dairy cows, examined
supplementation strategies for a high quality grass silage (dry matter (DM), 418 g/kg; crude protein
(CP), ...

Objective: To evaluate the use of nurse sows and post-weaning nutrition strategies for low wean weight (WW) pigs on lifetime growth and efficiency.
Methods: Animals (n = 270) were assigned to one of five treatments at 28 ...

Soil organic carbon (SOC) sequestration across
agroecosystems worldwide can contribute to mitigate the effects
of climate change by reducing levels of atmospheric
CO2. Stabilisation of organic carbon (OC) in the fine ...
