Standard milk tests include monitoring traits such as milk yield and quality. In addition to performing standard milk tests, it is now possible to evaluate metabolites that could act as potential biomarkers to determine milk properties. This study was conducted to identify the metabolomic parameters related to milk yield and quality in Awassi sheep. In our study, a total of 26 Awassi ewes, 13 with high milk yield and 13 with low milk yield, were examined. Liquid chromatography tandem mass spectrometry was used for metabolomic analysis. There was a statistically significant difference at different levels between the two groups in terms of aspartic acid, ornithine, anserine, and cystathionine levels (P<0.05 and P<0.01). A moderate negative correlation was determined between milk yield and aspartic acid (r=−0.63) and anserine (r=−0.52) levels (P<0.01). A significant negative correlation was found between lactose levels and lysine (r=−0.50), alpha-aminoadipic acid (r=−0.52), and hydroxylysine (r=−0.51) levels (P<0.01). The somatic cell count and alanine (r=0.49), aspartic acid (r=0.42), proline (r=0.42), alpha-aminoadipic acid (r=0.41), beta-alanine (r=0.43), and thiaproline (r=0.43) levels (P<0.05) showed positive correlation. Our results provide important insights into the metabolic events involved in sheep milk yield and milk quality which may guide further research to improve milk production and enhance the constituents of sheep milk.

The Large Hadron–Electron Collider (LHeC) is designed to move the field of deep inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting energy-recovery technology, it collides a novel, intense electron beam with a proton or ion beam from the High-Luminosity Large Hadron Collider (HL-LHC). The accelerator and interaction region are designed for concurrent electron–proton and proton–proton operations. This report represents an update to the LHeC’s conceptual design report (CDR), published in 2012. It comprises new results on the parton structure of the proton and heavier nuclei, QCD dynamics, and electroweak and top-quark physics. It is shown how the LHeC will open a new chapter of nuclear particle physics by extending the accessible kinematic range of lepton–nucleus scattering by several orders of magnitude. Due to its enhanced luminosity and large energy and the cleanliness of the final hadronic states, the LHeC has a strong Higgs physics programme and its own discovery potential for new physics. Building on the 2012 CDR, this report contains a detailed updated design for the energy-recovery electron linac (ERL), including a new lattice, magnet and superconducting radio-frequency technology, and further components. Challenges of energy recovery are described, and the lower-energy, high-current, three-turn ERL facility, PERLE at Orsay, is presented, which uses the LHeC characteristics serving as a development facility for the design and operation of the LHeC. An updated detector design is presented corresponding to the acceptance, resolution, and calibration goals that arise from the Higgs and parton-density-function physics programmes. This paper also presents novel results for the Future Circular Collider in electron–hadron (FCC-eh) mode, which utilises the same ERL technology to further extend the reach of DIS to even higher centre-of-mass energies.
