“…The concentrations of these peptides were shown to increase significantly following in ovo supplementation with a multi-strain probiotic and Zn-Gly chelate (group IV) or Zn-Gly chelate (group III). Literature data indicate that these proteins perform numerous functions in the body, including involvement in cell differentiation, the cell cycle, regulation of the immune response, metabolic processes, growth, development, and reproduction [70,71].…”

The aim of the study was to determine differences in the proteome and peptidome and zinc concentrations in the serum and tissues of chickens supplemented with a multi-strain probiotic and/or zinc glycine chelate in ovo. A total of 1400 fertilized broiler eggs (Ross × Ross 708) were divided into four groups: a control and experimental groups injected with a multi-strain probiotic, with zinc glycine chelate, and with the multi-strain probiotic and zinc glycine chelate. The proteome and peptidome were analyzed using SDS-PAGE and MALDI—TOF MS, and the zinc concentration was determined by flame atomic absorption spectrometry. We showed that in ovo supplementation with zinc glycine chelate increased the Zn concentration in the serum and yolk sac at 12 h post-hatch. The results of SDS-PAGE and western blot confirmed the presence of Cu/Zn SOD in the liver and in the small and large intestines at 12 h and at 7 days after hatching in all groups. Analysis of the MALDI—TOF MS spectra of chicken tissues showed in all experimental groups the expression of proteins and peptides that regulate immune response, metabolic processes, growth, development, and reproduction.

“…In addition to their roles as cytokines that play a crucial role in fetal development by promoting cell proliferation and inhibiting apoptosis, GH and PRL are also important mediators of embryogenesis, organ development, and postnatal growth [33]. The biological effects of GH receptor (GHR) and PRL are either local or systemic depending on how the hormone binds to cell surface receptors and initiates signaling cascades [34].…”

Reproductive efficiency is a crucial factor in the economic viability of small ruminant exploitation. In spite of this, few producers utilize the available reproductive technologies related to hormonal interaction, which are vital for the economic sustainability of their operations. Therefore, this review aimed to investigate the potential effects of reproductive alterations and hormone interactions during pregnancy and lactation and to determine advanced technologies for sheep reproduction. In the modern era, breeding techniques, nutrition, reproduction, and management techniques are used to produce more and better quality livestock. A combination of estrous synchronization and genetic improvements for small ruminants is needed to increase reproduction efficiency, productivity, and quality. A proper match between sheep breeds and nutritional and production environments will allow animals to express their genetic potential for enhanced production. In sheep, little information is available regarding the reproductive physiology during pregnancy and lactation. The availability of such information would enhance sheep production and reduce economic losses through improved dam performance and lamb survival. Understanding ewe reproductive physiology during pregnancy and lactation is essential for flock managers to determine their reproductive potential. Using advanced reproductive technologies could enhance the productivity of sheep, which are the most abundant ruminant livestock species.

Fennel seed (Foeniculum vulgare Mill.) essential oil (FEO), which is rich in the phytoestrogenic compound trans‐anethole, interacts with oestrogen receptors and influences molecular targets within cells and hormonal responses. This study examined the effect of dietary encapsulated FEO inclusion levels on performance, reproductive hormone profiles, and gene expression in laying hens during the early and late phases. The study was conducted in two independent trials, each involving 210 Atak‐S laying hens that were randomly distributed into 3 experimental groups, each having 10 replicates with 7 hens. The dietary treatments included a basal diet without FEO (Control) and a basal diet supplemented with 175 (FEO175) or 350 mg (FEO350) of encapsulated FEO/kg for 12 weeks. The results showed that FEO350 treatment improved egg production, egg mass, and feed conversion ratio during both early and late phases (p < 0.05). Moreover, increasing FEO inclusion levels enhanced oestradiol, follicle‐stimulating hormone, luteinizing hormone and progesterone concentrations in both early and late laying hens, reaching peak levels at FEO350 (p < 0.05). FEO supplementation upregulated the expression of oestrogen receptor 2 (ESR2) and follicle‐stimulating hormone receptor (FSHR) (p < 0.05). Furthermore, FEO350 increased prolactin receptor (PRLR) expression during the early phase but decreased it during the late laying phase (p < 0.05). Positive correlations were observed between egg production and FSHR, ESR2 and steroidogenic acute regulatory protein (STAR) expression, with a negative correlation for PRLR (p < 0.05). In conclusion, 350 mg FEO/kg was found to be the most effective level for enhancing layer performance.
