Effects of sex, litter size and periconceptional ewe nutrition on the ewe-lamb bond.
, 2009 Undernutrition restricted to the time around conception in sheep alters endocrine and metabolic responses in the offspring. Studies in rats suggest that such an early insult can also alter the behaviour of the offspring.

PLoS ONE, 2019 Greater rates of genetic gain can be achieved by selecting animals born to younger parents. However, little is known about the lifetime performance of dual purpose ewes (Ovis aries) that are born to primiparous ewe lambs (8 to 9 months old at breeding ...

Animal, 2010 Mid-pregnancy shearing has consistently been shown to increase lamb birth weight, which can lead to an increase in lamb survival rates. However, shearing ewes during the winter months and under outdoor pastoral farming conditions can expose the recently ...

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 ...

Anthelmintic resistance in sheep nematodes in Australia: a compilation of recent test results
Australian Veterinary Journal, EarlyView.Objective The results of recent faecal egg count reduction tests (FECRTs) were collated to provide an indication of the prevalence and severity of anthelmintic resistance in sheep nematodes across Australia and of changes in comparison to earlier testing reports.

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 ...

Basal body temperature as a biomarker of reproductive state in ewes: A multi‐method comparison
Australian Veterinary Journal, EarlyView.This study quantified body temperature dynamics throughout reproductive stages in crossbred ewes based on complementary monitoring techniques. Five ewes from a semi‐extensive farming system were included in two sub‐trials: animals were first assessed in the prepubertal stage and, subsequently, an oestrous cycle was induced by intravaginal progesterone ...

Multiple congenital skeletal malformations in a lamb associated with dystocia in a Yankasa ewe
, 2002 A ewe was relieved of dystocia by manual manipulation. The lamb was found to be malformed. There were multiple skeletal malformations which included brachygnathia, arthrogryposis and kyphoscoliosis. Other malformations included patella absence, resulting

Influence of body weight on reproductive activity in Sarda female lambs
Italian Journal of Animal Science, 2010 One way to improve reproductive performance of ewes is through extending its lifetime productivity. Breeding ewe lambs is one method of improving the reproductive performance in the sheep.
