The effect of maternal nutrition during mid- to late- pregnancy on ewe and lamb behaviour and the association with lamb survival : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Animal Science at Massey University, Palmerston North, New Zealand [PDF]

, 2015
Lambing percentage in New Zealand has increased by almost 30% in the last 20 years. This increase is associated with a greater percentage of twin- and triplet-born lambs which have lower survival rates than singletons.

The Effect of Alternative Sheep–Beef Enterprise Mixes on Farm Productivity, Profitability and Predicted Enteric Methane Emissions in North Island Hill Country Farms

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Sheep or beef cattle (cattle) share of total farm feed consumed, measured in stock units (SU) on New Zealand farms, is often adjusted depending on the profitability of each enterprise. The impact of these adjustments on whole‐farm productivity, profitability and predicted methane (CH4) output has not been recently explored. A system dynamics model of a

Freeze‐dried Lactobacillus spp. improved average daily liveweight gain and reduced methane intensity in growing lambs

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3857-3865, April 2026.
Abstract BACKGROUND Direct fed microbials (DFM) are natural and safe enteric methane mitigants for ruminant livestock systems. While previous studies have demonstrated the effect of Lactobacillus spp. on methane mitigation, challenges remain in effectively delivering DFM in extensive grazing systems. The objective of this experiment was to evaluate the

Bactericidal, Bacteriostatic, and Fungicidal Activities of Clausena anisata Fruit and Its Compounds, Stigmasteryl 3‐Palmitate (a Phytosterol Ester) and Phellopterin (a Furanocoumarin), Against Some Clinical Pathogens

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
C. anisata fruit extract and its compounds demonstrated potent broad‐spectrum antimicrobial activity, notably against Klebsiella pneumoniae (MIC 0.625 mg/mL; MLC 2.5 mg/mL) and Candida albicans (MIC 0.0781 mg/mL; MLC 0.625 mg/mL). The findings highlight promising bactericidal and fungicidal potential of stigmasteryl 3‐palmitate and phellopterin against

Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)

Fisheries Management and Ecology, Volume 33, Issue 2, Page 246-259, April 2026.
ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...

Organic beef and sheep production (OF0147) [PDF]

, 2001
This is the final report from Defra project OF0147 To study the potential of organic farming in the hills and uplands, a comparison of organic and conventional production systems at similar stocking rates was made at ADAS Redesdale.

Simple Python‐based methods for analysis and drift‐correction of STM images

Journal of Microscopy, Volume 302, Issue 1, Page 39-49, April 2026.
Abstract A successful scanning tunnelling microscopy (STM) experiment relies on both delicate sample preparation and measurement, and careful image filtering and analysis to provide clear and solid results. Processing and analysis of STM images may result in a tricky task, due to the complexity and specificity of the probed systems.

α‐Adrenergic blockade impairs ductus venosus shunting during an acute period of fetal hypoxaemia without further deficits to cerebral oxygen delivery

Experimental Physiology, Volume 111, Issue 4, Page 1796-1807, 1 April 2026.
Abstract The fetal circulation has unique shunts, including the ductus venosus (DV), the tone of which dictates how much substrate‐rich blood returning from the placenta is streamed preferentially away from the liver and instead towards the heart. Herein, we aimed to use clinically relevant MRI techniques in sheep to measure indirectly induced changes ...

Methodological comparison of fetal brain 1H‐MRS data analysis techniques and gestational age analysis using LCModel in the fetal sheep brain

Experimental Physiology, Volume 111, Issue 4, Page 1597-1611, 1 April 2026.
Abstract Proton (1H) magnetic resonance spectroscopy (MRS) is a non‐invasive imaging technique that can be used to assess brain metabolism. Establishing reference levels of fetal brain metabolites in a translatable preclinical model is crucial for identifying subtle deviations from normal cerebral development. Herein, we developed a 1H‐MRS protocol for
