Summary: Pork cutting is crucial and the research findings show that carcass weight, sex, and breed composition have significant effects on the weight and proportion of meat cuts. The study also reveals correlations between meat cuts, carcass traits, and meat quality traits. The results provide important insights for breeding pig carcass cuts and composition.

Summary: This study constructs a time-dependent and non-relativistic advective accretion disc-corona model to investigate the X-ray emission properties of tidal disruption events (TDEs). The model reveals the correlation between the total X-ray luminosity and the mass gain rate and mass fallback rate of the seed disc. The late-time evolution of the total X-ray luminosity follows a power-law relationship. This research is crucial for understanding the physical processes involved in TDEs.

Summary: This study investigates the evolution of fallback discs interacting with millisecond magnetars. The research finds that in the first few days, the fallback disc cannot directly interact with the magnetosphere of the magnetar, which has implications for fallback disc models of gamma-ray burst afterglows.

Summary: Fallback in core-collapse supernovae is crucial in determining the properties of central remnants and could lead to the formation of a black hole hyperaccretion system. High accretion rates in neutrino-dominated accretion flows can result in the emission of anisotropic MeV neutrinos and strong gravitational waves. This study explores the effects of initial explosion energies, progenitor star masses, and metallicities on the spectra of anisotropic MeV neutrinos and the waveform of gravitational waves from such systems, with potential implications for CCSNe and progenitor star properties.

Summary: This study compared the carcass and meat quality traits of the Kadaknath chicken breed with commercial broilers. The Kadaknath had lower carcass and breast yields, but higher leg, wing, back, and neck yields compared to broilers. The meat of the Kadaknath was darker and more yellow in color, had a lower pH decline, and higher protein content, and lower fat, moisture, and ash content than broilers. Additionally, Kadaknath meat had a richer amino acid composition, including those associated with sweet and umami taste. Both genotypes were similar in meeting the daily requirements of indispensable amino acids for adult humans.

Summary: This study investigated the effect of adding natural sorbents to pig feed on the fatty acid content of pig meat and fat. The results showed that the sorbents had limited effects on muscle tissue but had significant effects on kidney fat. The impact of different sorbents varied, but overall, they did not have a negative effect on the nutritional and pro-health quality of pig adipose tissue during fattening.

Summary: This study aimed to investigate the effects of different dietary levels of alfalfa on carcass traits, meat quality, amino acid and fatty acid composition, and the intestinal microbiota of Heigai pigs. The results showed that adding 30% alfalfa meal improved meat quality and changed the intestinal microflora composition without affecting the growth performance of Heigai pigs.

Summary: The study evaluated the efficacy of dietary strategies to slow growth in late finishing pigs and their effects on carcass composition and pork quality. The results showed that several dietary strategies can slow finishing pig growth without behavioral vices, but changes to carcass composition and quality were also observed. Quality should be considered when choosing diets to slow growth.

Summary: High doses of zinc have been used as a prevention against weaned piglets' diarrhea for many years, but have been banned in the EU since 2022. There are studies on the potential of lower doses of zinc nanoparticles for prevention, but concerns about toxicity and bioaccumulation have been raised. This follow-up study focused on the impact of zinc nanoparticles on carcass classification and zinc retention in muscle tissue of weaned piglets.

Summary: This study compares the meat quality of Shaziling and Yorkshire pigs and identifies a potential indicator for superior meat quality in serum. The results show that Shaziling pigs have certain advantages over Yorkshire pigs in terms of backfat thickness, loin eye area, and meat quality. Furthermore, serum L-carnitine content is positively correlated with meat quality.

Summary: The study proposes a new formation pathway for heavy binary neutron stars and light black hole-neutron star binaries, based on simulations of supernova explosions and accretion onto neutron star companions. This pathway can explain the formation of certain gravitational-wave events and predicts the assembly of others.

Summary: Increased incidence of myopathies and changes in broiler carcass composition can lead to poor visual appearance and carcass condemnation, resulting in economic losses. This study evaluated the incidence of white striping (WS), wooden breast (WB), and carcass composition in different genetic lineages of broilers fed with different dietary nutrient densities. The results showed that broilers from the Embrapa 021 lineage had a lower incidence of WS and WB, as well as lower moisture and protein content in the carcass. On the other hand, rapid growth broilers were more susceptible to myopathies and had higher moisture and protein content in the carcass.

Summary: Variation in nutrition has a significant impact on growth, body composition, and the ability of animals to perform. However, full compensation may not occur. A factorial serial slaughter study examined the effects of prior nutritional restriction, dietary energy density, and supplemental rumen undegradable protein (RUP) on intake, growth, and body composition of lambs. The study found that restricted-refed lambs were lighter and leaner at harvest and had proportionally larger viscera. Increasing dietary energy density led to smaller rumens and larger livers. Understanding how prior nutrition affects current performance is crucial for improving our understanding of animal performance and response to change.

Summary: This study investigated the impact of on-farm rest period on carcass composition, meat quality, and stress indicators in culled sows. The results showed that a longer rest period led to higher dressing percentage, backfat thickness, and shoulder weight. The highest shoulder percentage was found in the 3-4 week rest period groups, while 1 week rest period had the highest percentage for the belly-rib part. The rest period also influenced the pH values, drip loss, thawing loss, cooking loss, and tenderness of the meat. Additionally, the cortisol level, a stress indicator, was lowest in the 6-week rest period group.
