Summary: The intensity of estrous expression is linked to ovulation, ovarian and uterine function, fertility, social hierarchy, and housing system. Studies have shown that longer and more intense estrus periods are associated with improved pregnancy rates and reduced pregnancy losses. Additionally, the behavior displayed near artificial insemination can impact gene expression related to the immune system and endometrium.

Summary: The study aimed to determine the association between the time of artificial insemination (AI) and pregnancy per AI (P/AI) in lactating Holstein cows. Factors such as estrus event characteristics and timing were found to impact P/AI. Primiparous cows had higher P/AI, and first AI postpartum yielded greater P/AI. High estrus intensity was positively associated with P/AI.

Summary: The observational study aimed to identify factors associated with estrous duration and intensity in lactating Holstein cows, finding a strong correlation between DU and PA, with cows exhibiting high PA having greater odds of pregnancy. Increased temperature-humidity index, short interestrus intervals, and changes in rumination were associated with DU and PA.

Summary: The study found that in seasonal calving pasture-based systems, the accuracy of estrus detection was lower at first insemination but higher at repeat insemination. Factors such as absence of mounting abrasion may increase the risk of inaccurate estrus detection.

Summary: The study found that administering GnRH at the time of artificial insemination did not significantly impact ovulation rate, post-AI progesterone levels, and pregnancy rate in cows detected in estrus. Further research is needed to explore the relationship between GnRH administration at AI and activity levels in herds using automated monitoring systems.

Summary: The study found that estrus induction in Holstein heifers had no negative effects on estrus indicators and fertility compared to natural estrus. When using different types of semen for artificial insemination, there may be variations in pregnancy rates between induced estrus groups.

Summary: The Ovsynch protocol has been proven to increase pregnancy per artificial insemination (P/AI) in lactating dairy cows, compared to cows inseminated after a detected estrus. Implementing timed artificial insemination (TAI) programs has been an important factor in the significant improvement of reproductive performance in lactating dairy cows in the United States over the past 20 years.

Summary: Studies have shown that the composition of milk from dairy cows varies during estrus, with changes in fat, protein, and lactose levels being documented. This research aimed to investigate the effects of estrus on milk MIR spectra and production traits, with potential implications for estrus detection in dairy cows. Further analysis is needed to fully explore the use of milk MIR spectra in estrus detection.

Summary: Estrus detection is crucial for prompt artificial insemination in dairy farms. Conventional methods using electronic devices can be expensive and affect the cows' mood, while continuous observation can lead to errors. Therefore, CowXNet, an automatic estrus detection system, was designed to help farmers detect estrus cows using only a camera and computer. CowXNet showed promising results, correctly detecting estrus behavior intervals in 83% of cases.

Summary: The primary objective of this study was to develop an automated infrared thermography platform capable of identifying cows in estrus by measuring skin temperature and tail movements. The study also evaluated the accuracy of the platform compared to in-line milk progesterone analysis and found that skin temperature and tail movements were associated with the estrus status of cows.

Summary: Heat stress poses a significant threat to the economic viability of the dairy industry, particularly for larger farms seeking expansion. This study developed and tested a reliable method using a compact ear tag device to monitor the body temperatures of dairy animals. The device wirelessly transmitted real-time subcutaneous temperatures using an injectable RFID biosensor. The findings showed that subcutaneous ear-base temperature could accurately predict core body temperature, allowing for timely detection and mitigation of heat stress in dairy cattle.

Summary: The study evaluated the lipid composition of biopsied and sexed embryos produced in vivo or in vitro from Holstein heifers, revealing an enrichment of triglycerides and oxidised glycerophospholipids in IVP embryos. The slow freezing process affected the lipid profiles of both IVP and IVD embryos similarly. Lysophosphatidylcholine content was found to be reduced during freezing/thawing, indicating its sensitivity to cryopreservation.

Summary: This research reveals the crucial role of Ferroptosis Suppressor Protein 1 (FSP1) in regulating the development and quality of porcine early embryos. Inhibition of FSP1 impairs blastocyst formation, induces glutathione-independent ferroptosis, and leads to oxidative stress due to mitochondrial dysfunction.

Summary: This study examined the effects of plant bioactive compounds on the survival and growth parameters of ovine preantral follicles granulosa cells (GCs) and the expression of key developmental genes. The results showed that KAE, MYR and QUE had dose-dependent responses on the morphological and functional parameters of the cells, with KAE being the most potent in augmenting ovarian functions.

Summary: The presence of a more efficient glycolysis mechanism depending on pyruvate in stallion spermatozoa can counteract the detrimental effects of higher glucose concentrations. Incubating spermatozoa with 10 mM pyruvate in a modified Tyrode's media with 67 mM glucose showed increased motility and maintained viability. This improvement is attributed to the conversion of lactate to pyruvate and increased NAD(+) enhancing glycolysis efficiency.

Summary: Ongoing progress in mRNA-Sequencing technologies has contributed to the refinement of assisted reproductive technologies. This study utilized mRNA-Seq datasets of various mammalian species to analyze differential transcript usage (DTU) and identified ten cross-species DTU genes. Gene Ontology (GO) term enrichment analysis revealed the involvement of these genes in RNA and cell-cycle control mechanisms, suggesting their importance during oocyte maturation. Further exploration of these genes' transcript isoforms may lead to the discovery of novel markers for reproductive technologies.

Summary: This study found that Nobiletin (NOB) can promote the cryosurvival and embryo development of porcine sperm after in vitro fertilization (IVF). The addition of NOB improves sperm motility, acrosome integrity, viability, and mitochondrial membrane potential, reduces lipid peroxidation, and increases cleavage and blastocyst formation rates. Furthermore, NOB treatment upregulates the expression of genes related to pluripotency and cell differentiation in the resulting embryos.

Summary: This study investigated the cytotoxicity and toxicological mechanisms of fluorochloridone (FLC) on cultured goat Sertoli cells. The results showed that FLC exposure induced oxidative stress, promoted apoptosis and autophagy, inhibited lysosomal biogenesis, and blocked autophagic flux in goat Sertoli cells. FLC also caused mitochondrial dysfunction and disturbed mitophagy, leading to cell apoptosis. The antioxidant N-acetyl-L-cysteine (NAC) reduced FLC-induced ROS accumulation and reversed the disorder of autophagy levels.

Summary: The study evaluated the effects of E2 treatment on Nelore heifers on day 15 of the estrous cycle, finding that E2 promoted an increase in PGFM concentrations and accelerated functional and structural luteolysis by upregulating the expression of PGR and OXTR. This suggests that within 3 hours after E2 stimulus, the expression of these receptors is associated with triggering luteolysis in cattle.

Summary: This study evaluated the effect of phospholipase C (PLC) on the capacitation of cryopreserved ovine semen. The results showed that the inhibitor U73122 can prevent premature capacitation and acrosome reaction induced by the freezing procedure, without affecting the kinetics and integrity of the sperm membranes.
