The neuroendocrine hormone melatonin is associated with circadian rhythms and has antioxidant and vasodilative properties. In cattle, melatonin rescues fetal growth during maternal nutrient restriction in a seasonally dependent manner, but melatonin research in swine is limited. The objective of this study was to evaluate the effects of dietary melatonin supplementation during mid to late gestation on circadian rhythm and muscle growth and development of the longissimus dorsi in utero and postnatally.

- Australia struggles to effectively monitor the HIV epidemic due to insufficient population data, prompting this study to use incidence prevalence ratios (IPRs) to assess the epidemic trends among specific groups: men who have sex with men, women, and people who inject drugs.
- The study employed mathematical modeling to create IPRs from various data sources, comparing them against benchmarks based on life expectancy after HIV acquisition, illuminating trends from 2015 to 2022.
- The findings showed a significant decline in IPRs across all groups, with overall rates dropping by 80%, and many groups surpassing benchmarks, indicating a positive trend in managing HIV transmission in Australia.
The in utero environment is key to both fetal and postnatal growth and development. The objective of this study was to determine if administration of an acute low-dose lipopolysaccharide (LPS) to gestating sows during mid to late gestation and postweaning would alter the offsprings metabolomic profile of the longissimus dorsi (LD) and muscle ultrastructure. Pregnant Camborough sows were randomly assigned to receive LPS (LPS; n = 7) at a dose of 2.

- - The study investigates the effects of seminal plasma uterine priming at estrus on various reproductive and developmental outcomes in cattle, focusing on the uterus of the dam and her offspring.
- - Cows were treated with either seminal plasma or a control, and various measurements including uterine biopsies, embryo size, and calf growth were taken at distinct stages of gestation and post-birth.
- - Results showed changes in uterine gene expression, with notable differences in embryo size and calf heart girth, but no significant effects on birth weight or liver gene expression in the offspring at 30 days.
