Genetic analysis of a maternal assistance score in sheep
AnimalMaternal behaviour is important for lamb survival, as ewes perform many behaviours that affect the chances of a lamb surviving. Collecting maternal behaviour data directly at lambing is time−consuming and not considered suitable for acquiring the large ...

Animal, 2022 Sheep meat producers derive the majority of income from sales of weaned lambs, determined by flock conception rates, litter size, and lamb survival. Field data from commercial flocks can inform sensitivity analyses of the effect of litter size on flock ...

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.

Animal Research and One Health, EarlyView.Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...

Grassland Research, EarlyView.Effect of three‐way interaction between soil tillage, drainage and depths on soil properties in reseeded pastures. Abstract Background Grassland reseeding typically requires intensive tillage. This disrupts soil nutrient dynamics, especially under varying drainage conditions. Methods This study evaluated the combined effects of tillage legacy, drainage

Maternal behaviour and lamb survival: from neuroendocrinology to practical application*
Animal, 2014 Parental care promotes offspring survival and, for livestock species, this care is provided solely by the mother. Maternal behaviour in the sheep has been exceptionally well-studied compared with other species and many of the underpinning biological ...

The potential interaction between ewe body condition score and nutrition during very late pregnancy and lactation on the performance of twin-bearing ewes and their lambs [PDF]
Asian-Australasian Journal of Animal Sciences, 2017 Objective The present study aimed to determine the impact of ewe body condition score (BCS) (over a range of 2.0 to 3.0) and nutritional treatments (consisting of differing herbage masses) during very late pregnancy and lactation and their potential ...

Animal, 2022 Genetic susceptibility to scrapie, a fatal disease of sheep and goats, is modulated by polymorphisms in the prion protein (PrP). Neither the frequency of the PrP genotypes nor their association with animal performance has been investigated in a large ...

Caffeine supplementation of ewes during lambing may increase lamb survival
Animal, 2018 Perinatal mortality of lambs is on average 20% of lambs born in extensive Australian grazing systems, constituting a substantial production loss and welfare concern. Hypoxia resulting from prolonged or difficult births contributes to lower rates of lamb survival, and caffeine may reduce the effects of hypoxia.
