Article Synopsis
- - The study investigates how exposure to diesel engine exhaust (DE) during pregnancy affects the long-term health of rabbit offspring, specifically focusing on their cardiovascular and metabolic profiles in adulthood.
- - Female rabbits were exposed to DE or clean air during gestation, and their offspring were monitored for various health metrics, revealing that males experienced more significant negative health consequences compared to females.
- - Findings indicate that male offspring exhibited signs of metabolic syndrome, such as increased blood pressure and altered cholesterol levels, while female offspring showed milder effects, highlighting sex-specific vulnerabilities to air pollution during development.
Forkhead Box L2 (FOXL2) is a member of the FOXL class of transcription factors, which are essential for ovarian differentiation and function. In the endometrium, FOXL2 is also thought to be important in cattle; however, it is not clear how its expression is regulated. The maternal recognition of pregnancy signal in cattle, interferon-Tau, does not regulate expression.

- Pregnant mares were studied to see how their diet impacts the growth and development of their foals, specifically looking at diets of only forage versus a mix of forage and cracked barley.
- Results showed that diet influenced insulin resistance and testicular maturation in colts, with those fed the barley/feed mix showing delayed maturity but better bone structure.
- Overall, the study suggests that the nutrition of both mares and foals plays a significant role in their growth and development, with potential negative effects on future reproductive health.
Background: Airborne pollution is a rising concern in urban areas. Epidemiological studies in humans and animal experiments using rodent models indicate that gestational exposure to airborne pollution, in particular diesel engine exhaust (DE), reduces birth weight, but effects depend on exposure duration, gestational window and nanoparticle (NP) concentration. Our aim was to evaluate the effects of gestational exposure to diluted DE on feto-placental development in a rabbit model.

This practice, however, was shown to correlate with an increased incidence of osteochondrosis in foals, which may be related to insulin sensitivity. We hypothesized that supplementation of the mare with barley in the last trimester of pregnancy alters the pre-weaning foal growth, glucose metabolism and osteoarticular status.

- In equids, the supply of nutrients to the fetus is influenced by the size of the uterus, which is linked to the mother's size, impacting both fetal and post-natal development as well as insulin sensitivity in the offspring.
- This study examined the effects of enhanced and restricted fetal growth in horses through embryo transfer techniques involving different horse breeds, analyzing the outcomes on weight gain, growth hormones, and glucose metabolism.
- Results showed that foals born from enhanced environments (P-D) were consistently heavier with improved insulin secretion, while foals from restricted environments (S-P) were lighter with different glucose metabolism responses, indicating that the nature of fetal growth influences post-natal health outcomes.
Prim'Holstein heifers selected for the "Fertil-" homozygous haplotype of QTL-Female-Fert ility-BTA3 showed a greater rate of early pregnancy failure and slower embryo development after IVM suggesting lower oocyte quality than those selected for "Fertile+". We aimed to ascertain intrafollicular factors related to lower oocyte quality in "Fertil-" cows. Analysis of individual oocytes showed meiotic progression delay in "Fertil-" compared with "Fertil+" dairy cows after in vivo maturation and IVM (P < 0.

Long-term effects of maternal feed restriction during the last third of pregnancy on growth, metabolism and behavior of female kids, with a focus on feeding behavior and emotional reactivity, were studied in goats. Female kids born to control (CONT, n=17) or born to feed restricted goats (REST, n=15) were artificially reared and monitored from birth to 24 months of age.

Methods: Over three successive years, 3 groups of 10 mares were kept under natural photoperiod.
