Summary: The study found that dietary supplementation of AKG did not significantly affect the cholesterol and total fat content of egg yolks, but resulted in both positive (reduced n-6 FA and increased MUFA) and negative (reduced PUFA and n-3 FA, increased TI and n-6/n-3 ratio) changes in the fatty acid profile.

Summary: This study investigated the impact of ozone treatment on the volatiles and fatty acids of egg yolks. After ozone treatment, the composition and content of volatiles and fatty acids in the egg yolks were significantly altered. With proper ozone treatment (30 min), the aldehyde content in the egg yolks increased from 78.08% to 94.63%, and the relative content of dibutyl amine decreased from 1.50% to 0.00%. There were no significant differences in the types of fatty acids in the egg yolks after ozone treatment, but there were differences in their relative contents. The results suggest that ozone technology could be applied in the egg yolk processing industry.

Summary: This study investigated the effects of dietary pomegranate seed oil supplementation on the performance and egg quality of laying hens. The results showed that there were no significant differences in body weight, feed intake, cracked and thin-shelled eggs, and egg weight among different levels of pomegranate seed oil supplementation. However, the addition of 250 and 500 mg of pomegranate seed oil tended to improve egg production and egg mass. Additionally, the inclusion of pomegranate seed oil increased eggshell weight, yolk index, and the content of conjugated linoleic acid and polyunsaturated fatty acids in the egg yolk.

Summary: The present study aimed to evaluate the effects of dietary free fatty acid (FFA) content and the degree of saturation on egg quality, yolk fatty acid (FA) profile, and yolk cholesterol content. The results showed that the effect of varying dietary FFA levels on egg quality and yolk composition was not as significant as the differences in dietary fat sources.

Summary: This study investigated the effects of Akkermansia muciniphila (A. muciniphila) on lipid metabolism and egg quality in laying hens. The results showed that A. muciniphila supplementation could efficiently improve lipid metabolism, decrease body weight and fat deposition, and improve yolk lipid profile in laying hens. It also suggested that different preparations of A. muciniphila, including live, pasteurized, and lyophilized, have the potential for use as additives to improve laying hen production.

Summary: Conjugated linoleic acid (CLA) supplementation in lightly exercising horses may result in mitochondrial adaptations and protection against myofiber perturbation in skeletal muscle. Significant differences were observed in mitochondrial enzyme activities and antioxidant status between horses supplemented with soybean oil and CLA. Superoxide dismutase activity tended to increase over time in the soybean oil group, while glutathione peroxidase activity tended to be higher in the soybean oil group compared to the CLA group at week 12.

Summary: The effects of adding fat to sow diets on reproductive and growth performance of sows and piglets are influenced by various factors. Adding fat during late gestation and lactation decreases feed intake but tends to increase energy intake. It has no significant impact on litter weights at birth and weaning, but it may increase the total number of piglets at birth. Fat supplementation can increase milk fat concentration in sows and shorten the wean to estrus interval.

Summary: The aim of this study was to investigate the effects of dietary malic acid supplementation on skeletal muscle fiber-type transition during the nursery period and subsequent meat quality in finishing pigs. The results showed that supplementation with malic acid for 28 days increased the percentage of oxidative fibers in weaned piglets, along with increased aerobic oxidation in serum and longissimus thoracis (LT) muscle. In addition, the activities of total antioxidant capacity and glutathione peroxidase in serum were increased. Furthermore, dietary malic acid supplementation during the nursery period tended to increase the pH(24h) and significantly decreased drip loss in the LT muscle of finishing pigs. The content of total saturated fatty acids (SFA) and total monounsaturated fatty acids in the LT muscle was significantly decreased, while the ratio of polyunsaturated fatty acids to SFA tended to increase. In conclusion, dietary malic acid supplementation during the nursery period can effectively increase antioxidant capacity and oxidative fibers' percentage in weaned piglets and improve the water holding capacity and nutritional values of pork in finishing pigs.

Summary: In recent years, there has been an increase in the occurrence of fowl adenovirus 2 (FAdV-2) in China, posing a significant threat to the poultry industry. This study investigated the epidemiology, phylogenetic relationship, genomic characteristics, and pathogenicity of FAdV-2. The results showed that FAdV-2 was the most commonly detected serotype among various FAdV serotypes. Genetic analysis revealed that these FAdV-2 strains formed a distinct branch within the FAdV-D group and had a high nucleotide similarity with reference strains. Recombination analysis identified recombination events between FAdV-2 and FAdV-11 in some strains. Pathogenicity experiments demonstrated that a recombinant FAdV-2 strain caused a high mortality rate and more severe disease in chickens. These findings contribute to our understanding of FAdV-2 and provide a basis for vaccine development.

The results showed that perceived severity and perceived benefits positively influenced vendors' self-efficacy in the wholesale market, while perceived barriers negatively affected self-efficacy in both the wholesale and retail markets. Moreover, cues to action mediated the relationship between perceived severity, perceived benefits, and self-efficacy, and also mediated the effect of perceived susceptibility among wholesale market vendors.
