9. The Role of Early Life Nutrition in the Biological Programming of Growth and Reproductive Development of Female Ruminant Livestock Species.

29/09/2026 - Growth and reproductive efficiency is fundamental to the biological efficiency and profitability of livestock production systems, and is heavily influenced by nutrition, and, in particular, early...

249. Award Talk: From Nutrition to Elongation: Uterine Histotroph Programs Early Conceptus Development in Ungulates.

29/09/2026 - Early pregnancy loss during the peri-implantation period remains a major biological and economic constraint in livestock species, with 20-40% of embryos failing to establish pregnancy. In pigs and...

134. Preconceptional Maternal Nutrition Affects Postnatal Growth Performance in Singleton Female Lambs.

29/09/2026 - Maternal nutrition prior to conception is increasingly recognized as an important window for developmental programming, with the potential to influence offspring growth and later reproductive...

96. Genetic Analysis of Longevity in Brazilian Santa Inês Sheep.

29/09/2026 - Santa Inês is the most common hair type sheep breed in Brazil and is highly relevant to commercial production systems, especially in the Northeast region due to its adaptability to tropical...

PS13-25. Effects of Feeding Level on Pregnancy Performance, Metabolic Responses, and Reproductive Efficiency in Primiparous Ewes and Their Offspring.

29/09/2026 - Maternal nutrition is a key determinant of metabolic regulation, fetal development, and reproductive efficiency in sheep. This study evaluated how three gestational feeding levels 80%, 90%, and 100%...

29/09/2026 - Ram fertility and reproductive efficiency are critically important factors of productivity in the sheep industry. Reproductive seasonality, regulated by the photoperiod cycle, gestation length, and...

8. Pre-breeding body condition score influences reproductive efficiency and ewe productivity but is not associated with late-gestation metabolic status or lamb health in fall-lambing Rambouillet ewes.

10/07/2026 - Pre-breeding nutrition has long been recognized as a major contributor to reproductive success in livestock, influencing dam body condition, health, and reproductive cyclicity. In turn, suboptimal...

3. Effects of repeated low-dose maternal lipopolysaccharide exposure during the periconception period on ewe immune responses and lamb performance.

10/07/2026 - Gram-negative bacterial endotoxins can impair reproduction through activation of innate immune responses. However, the effects of low-dose endotoxin exposure during the periconception period on...
