: Oestrus detection is currently at the top of the factors limiting the success of artificial insemination in dairy herds. This limitation becomes more pronounced as milk production increases because of higher metabolic clearance rates of steroid hormones leading to low circulating oestradiol concentration near oestrus. The standard OvSynch has overcome this problem by enabling fixed-time artificial insemination, for it synchronises follicular wave emergence, luteolysis, and ovulation. However, it did not improve fertility compared to cycles with spontaneous ovulation, which motivated the development of “fertility programs”. These later are nothing but improved OvSynch protocol. This article explains what went wrong with the original OvSynch protocol, discusses the improvements made by “fertility programs”, and highlights the advantages and limits of the newly tested molecules.

: Genetic modifications can improve the health status and disease resistance of farm animals. In the previous study, genetically modified (GM) sheep overexpressing toll like receptor 4 ( TLR4 ) were produced. The GM sheep had stronger ability to eliminate invasive microbes compared to the wild-type (WT) sheep. Physiological status and immune homeostasis, blood parameters, body composition, and gastrointestinal microbial diversity were evaluated in this study to elucidate the effects of TLR4 overexpression. In a set of 10 GM rams, the TLR4 mRNA and protein expression levels in the peripheral blood mononuclear cells (PBMCs), muscle, kidney, and spleen were higher than those of the WT ( n = 10; P < 0.05). No significant differences in the parameters of red blood cells, white blood cells, platelets and in the composition of circulating T-lymphocyte subsets were observed between the GM and WT sheep ( P > 0.05). Of the biochemical parameters, only total protein levels differed (were higher) in the GM sheep than in the WT sheep ( P < 0.05) while no significant differences were observed for the other indices ( P > 0.05). GM and WT sheep showed similar offal weights and muscle fatty acid and amino acid compositions ( P > 0.05). Furthermore, TLR4 overexpression did not affect the community structure of the gastrointestinal tract microbiota. Eleven KEGG pathways associated with the TLR4 gene, physiology and biochemistry, growth and metabolism, fatty acids, and amino acids did not demonstrate significant differences between the GM and WT sheep ( P > 0.05). In conclusion, TLR4 overexpression had no principal or adverse effects on the physiological development and health of sheep, except for the general mRNA and protein expression levels.
