Project description:Primiparous sows were randomly allocated to two treatments and were separated from piglets 8h daily from Day 21 of lactation companied with daily boar exposure for oestrus detection until weaning (Day 28). Gene expression of Day 9 embryos were compared between control sows (FE; sows artificially inseminated when in heat during lactation ) and Skip-a-Heat sows (SE; sows in heat during lactation and artificially inseminated on the following oestrus cycle). Stimulating lactational oestrus then two mating strategies were applied to primiparous sows; 1)FE; sows were in heat during lactation and received artificial insemination) and Skip-a-Heat sows (SE; sows were in heat during lactation and received artificial insemination at fallowing oestrus cycle).

Project description:Exposure to intrauterine heat stress during late gestation affects offspring performance into adulthood. However, underlying mechanistic links between thermal insult in fetal life and postnatal outcomes are not completely understood. Utilizing RNA Sequencing, this study characterized the mammary gland transcriptome of heifers that were gestated under maternal conditions of heat stress or cooling, i.e., in utero heat stressed (HT) vs. in utero cooled (CL). Mammary tissues were collected from three HT and three CL heifers during their first lactation.

Project description:Exposure to intrauterine heat stress during late gestation affects offspring performance into adulthood. However, underlying mechanistic links between thermal insult in fetal life and postnatal outcomes are not completely understood. Utilizing Reduced Representation Bisulfite Sequencing, this study evaluated DNA methylation of liver and mammary gland of bull calves and heifers that were gestated under maternal conditions of heat stress or cooling, i.e., in utero heat stressed (HT) vs. in utero cooled (CL). Liver samples from bull calves (CT = 5 and HT = 4) were collected at birth while mammary gland samples from heifers (CT = 3 and HT = 3) were collected during their first lactation.

Project description:Transcriptional profiling of Day 30 embryos (D30E) was performed. First parity sows were submitted to an ovulation-induction protocol, intermittent suckling (IS), during lactation. IS consisted of 8 h/d separation from their litters during the last 7d of a 28d lactation. During separation, sows received boar exposure. There were 3 treatments: control (C28, n=19), where piglets were weaned at D28 of lactation and were bred after weaning and two IS treatments: sows were either bred at their first induced estrus during lactation (IS21FE, n=18), or were “skipped” and bred at their second estrus (IS21SE, n= 17) which occurred after final weaning at D28. Sows were slaughtered and embryos were collected on D30 of gestation for DNA PCR sexing. Later, D30E from the same sex with similar weight were pooled for further microarray investigation. Stimulating lactational oestrus then two mating strategies were applied to primiparous sows. For the microarray experiment, three biological replicates (three sows) were chosen from each treatment group comparing control (C28) to either IS21FE or IS21SE. A pool of females and males D30E were chosen and pooled separately for each comparison.

Project description:Maternal stress occuring during gestation can influence the functioning of the stress and immune responses in offspring. Maternal supplementation with immunomodulatory compounds such as omega-3 polyunsaturated fatty acids may reduce inflammation associated with maternal stress, promoting offspring health and growth Sows were fed diets supplemented with microalgae or fish oil from gestation day 75 and were challenged with LPS on gestation day 112. Previously, LPS challenge in the male piglets of these sows resulted in differences in fever and cortisol responses among piglets from different maternal treatments. Therefore, the adrenal gland was chosen for microarray analysis to assess the effects of the maternal treatment on the gene expression within the hypothalamic-pituitary-adrenal axis.

Project description:Heat stress is one of the major abiotic stress factor that affects wheat yield. Especially, heat stress during grain filling affects grain yield besides reduced grain quality. So, in our present study, three genotypes with varied levels of tolerance to heat stress were chosen. They were subjected to heat stress at two stages for three days viz., early (11-14days-post-anthesis) and late (27-30dpa) grain filling independently under controlled conditions. At 14 and 30dpa, the spikes were harvested from control and stress conditions from all the three genotypes, grains were isolated and pulverized. Hence pulverized tissues are used for RNA extraction and further for transcriptome sequencing using HiSeq 4000. Data were analyzed to identify the genes involved in imparting heat stress tolerance.
