Large‐scale reproductive loss in sheep due to Border disease virus infection, New South Wales, Australia

Australian Veterinary Journal, EarlyView.
Border disease viruses (BDV) and bovine viral diarrhoea viruses (BVDV) are members of the Pestivirus genus in the family Flaviviridae. While BVDV is one of the most significant endemic viral infections of cattle in Australia, BDV infection is generally considered to be uncommon in Australian sheep.

Genetic Parameter Estimation for Plasma Biomarkers Associated With Energy Reserves During Critical Physiological Stages in Sheep

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The ability of ruminants to mobilise and restore body reserves (BR) over time, referred to as BR dynamics, is currently considered an interesting biological component to be included in breeding programs targeting enhanced BR resilience. However, genetic studies of proxies for BR levels and BRD remain scarce, particularly in small ruminants ...

Is intensification of reproduction rhythm sustainable in an organic sheep production system? A 4-year interdisciplinary study

Animal, 2009
A 4-year interdisciplinary study was performed to compare two organically managed sheep production systems, using 118 ewes and 24 ha each. The systems differed in the ewes’ reproduction rhythm: one lambing per ewe per year (1L/1Y), with the aim of ...

Current Trends, Future Prospects and Constraints of Whole Microalgae and Their Fractions as a Functional Feed Ingredient for Animals

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Microalgae are a highly diverse group of unicellular organisms that grow in a wide range of aquatic environments and are widely used as dietary supplements for both human and animal applications. Microalgae are rich in lipids, proteins, carbohydrates and other valuable bioactive components such as pigments, antioxidants and vitamins.

Antenatal betamethasone impairs markers of cardiac development and function in near‐term lambs

Experimental Physiology, EarlyView.
Abstract figure Summary of key molecular differences in the left ventricle of near‐term lambs exposed to antenatal betamethasone, compared to saline. Pregnant ewes received two doses of either saline (Saline) or betamethasone (Betamethasone, intramuscular, 11.4 mg) given 24 h apart, before delivery at 140 days of gestation (dG, term = 150 dG).

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

The effect of nutrition and body condition of triplet-bearing ewes during late pregnancy on the behaviour of ewes and lambs [PDF]

Asian-Australasian Journal of Animal Sciences, 2018
Objective Triplet-born lambs are less likely to survive to weaning than twin-born or single-born lambs. Appropriate ewe-lamb bonding behaviours and lamb vigour behaviours are necessary for survival of lambs.
