Summary: Epigenetic marks can explain part of the phenotypic variance in animal breeding models. Nanopore sequencing shows high correlation with bisulphite sequencing in identifying DNA methylation marks. Different sequencing methods highlight differentially methylated genes and positions of economic interest in animal breeding.

Summary: This study evaluated the effectiveness of steam as an additional method for depopulation of laying hens in a cage-free aviary system. The results showed that steam alone or in combination with heat can lead to faster mortality of hens, and the distribution of carcasses varies in different tiers.

Summary: This study aimed to evaluate the role of vitamin D in redox balance, insulin resistance, and its predicting value for subclinical pregnancy toxemia (SPT) in pregnant ewes. The results showed that ewes with insufficient vitamin D had significantly lower total antioxidant capacity (TAC) compared to ewes with sufficient vitamin D, and there were significant differences in metabolite concentrations between the two groups. Additionally, vitamin D was positively correlated with fructosamine, calcium, and TAC, and negatively correlated with non-esterified fatty acid (NEFA) and total oxidant status (TOS). Ewes with insufficient vitamin D had a higher risk of developing SPT two weeks prior to lambing and at lambing.

Summary: This study evaluated the use of an elevated platform with perforated surface and manure belt by fast-growing broilers. The results showed that broilers were able to effectively use the platform and ramp for resting throughout different stages of growth. Factors such as a shallow ramp incline, wide ramps, and appropriate materials contributed to the high utilization of the platform. Further research is needed to improve the platform design for undisturbed resting of broilers.

Summary: This study analyzed the hepatic transcriptomes and metabolomes of Changshun green-shell hens laying dark green and light green eggs to investigate the role of the liver in regulating eggshell color. The results suggest that hepatic melanin metabolism and transport are critical for eggshell coloration, and several candidate genes and metabolites were identified to potentially play important roles in this process.

Summary: SLC5A5 plays a crucial role in the development and function of chicken ovarian follicle granulosa cells, influencing cell proliferation, steroid hormone synthesis, and apoptosis. This discovery sheds light on the broader context of chicken ovarian follicle development and potential ways to improve egg-laying performance through molecular marker-assisted breeding technology.

Summary: This study compared the metabolites in the cecal digesta of differently colonized chickens and found that competitive exclusion products can affect the metabolite profiles in the chicken cecum, increasing the abundance of nucleotides, amino acids, and vitamins, while decreasing the abundance of compounds derived from plant feed.

Summary: This study investigated the lipid composition and metabolic pathways of goose meat, revealing changes in intramuscular fat deposition and lipid composition with age. Glyceride molecules showed significant changes and played a pivotal role in intramuscular fat deposition. Pathway analysis identified glycerophospholipid and glyceride metabolism as the most significant pathways associated with lipid changes during goose growth.

Summary: This study examined the effects of frozen storage on lipid and cholesterol concentrations, as well as fatty acid distribution, in wooden chicken breast meat. The results showed that wooden breast myopathy led to lower levels of beneficial polyunsaturated fatty acids, such as DHA, EPA, and ARA, in chicken meat. Prolonged storage further impaired the nutritional value of the meat.

Summary: This study investigated the effects of monochromatic LED lights on liver glycogen and lipid synthesis in broilers. The results showed that liver, abdominal fat, and abdominal fat indices increased with age. Liver glycogen and triglyceride contents also showed an increasing trend. mRNA levels of several genes related to glycogen and lipid synthesis in the liver varied with different light sources and ages. Total antioxidant capacity and liver superoxide dismutase contents increased with age and light source.

Summary: This study aimed to compare the quality characteristics and compounds concentrations in eggs from different breeds and lines of hens. The results showed significant differences in various egg quality parameters, as well as variations in lutein content, vitamin D content, cholesterol content, and fatty acid contents. It was also found that the genetic differences between breeds and lines of hens have a significant impact on the quality of eggs.

Summary: This study investigated changes in the saliva and serum proteome of dogs with hypothyroidism using TMT labelling and LC-MS/MS. The findings showed that this disease induces alterations in the saliva and serum proteome, reflecting physiological and pathological changes in the immune system, metabolism, skin, and coagulation. The downregulation of LDH in saliva may serve as a potential biomarker for canine hypothyroidism.

Summary: This study tested synchronization protocols without progestogens during the luteal phase in gilts. The results showed that the protocols based on PGF and hCG were effective in reducing the interval between estrus in gilts. Additionally, the hCG2 protocol had negative effects on the number of piglets born alive and total litter size.
