Body condition score and weight are effective targeted selective treatment indicators for gastrointestinal nematodes in premating ewes. [PDF]

Vet Rec
Abstract Background Ewe reproductive performance is key for flock profitability but can be impacted upon by gastrointestinal nematode (GIN) infections. Farmers commonly deworm ewes pre‐mating, yet concerns regarding anthelmintic resistance increase pressure to reduce wormer use.

Associations among Mammary Ultrasound Measurements, Milk Yield of Non-Dairy Ewe Lambs and the Growth of Their Single Lambs

Animals, 2021
Mammary cistern size was positively correlated with milk yield of mature dairy ewes, but the association in ewe lambs is unknown. This experiment aimed to examine the associations between mammary ultrasound measurements and the milk yield of ewe lambs at

Mutual recognition between ewes and lambs [PDF]

Reproduction Nutrition Développement, 1980
Studies to investigate the relative value of sight, hearing and smell in mutual recognition between ewes and lambs are described. The method used was to alter clues that could aid in recognition, rather than interfering with the animal's sensory perception. When lambs were coloured with powdered dyes to change appearance, this produced marked avoidance

Effects of grass and maize silage feed value, offering soybean meal with maize silage, and concentrate feed level in late pregnancy, on ewe and lamb performance

Animal, 2021
In many countries, daily herbage accumulation on pasture declines towards zero during the winter period; thus, many pregnant ewes are housed and offered conserved forages supplemented with concentrate prior to parturition.

POSTNATAL UTERINE DEVELOPMENT IN INVERDALE EWE LAMBS [PDF]

Biology of Reproduction, 2007
Postnatal development of the uterus involves, particularly, development of uterine glands. Studies with ovariectomized ewe lambs demonstrated a role for ovaries in uterine growth and endometrial gland development between postnatal days (PNDs) 14 and 56. The uterotrophic ovarian factor(s) is presumably derived from the large numbers of growing follicles

The Impact of Feeding Organic Trace Minerals Using Advanced Chelate Technology on Reproductive Efficiency and Blood Parameters in Ghezel Ewes. [PDF]

Vet Med Sci
Supplementing the flushing diet with organic trace minerals based on advanced chelate technology enhanced the reproductive performance of ewes as compared with inorganic trace minerals. ABSTRACT Background The bioavailability of trace minerals (TM) in a diet is important for improving reproductive performance and fertility parameters.

Plane of nutrition during the rearing phase for replacement ewes of four genotypes: II - effects on performance during first pregnancy and to weaning, and of their progeny

Animal, 2018
Plane of nutrition (PN) offered to ewe replacements during the rearing phase (8 to 17 months) and first pregnancy may affect reproductive and progeny performance when replacements are joined at ~19 months.
