Effects of 4-Hydroxy-2,5-dimethyl-3(2H)-furanone supplementation on growth performance, serum antioxidant capacity, rumen fermentation characteristics, rumen bacterial quorum sensing, and microbial community in Hu sheep.

Objective: This study aimed to investigate the effects of 4-Hydroxy-2,5-dimethyl-3(2H)-furanone on growth performance, serum antioxidant capacity, rumen fermentation characteristics, rumen microbial LuxS/AI-2 quorum sensing, and community composition in Hu sheep.

Methods: Twenty-two male Hu sheep with similar body weights and ages were evenly divided into two groups: the control group, which was fed a basal diet (n=11, CON), and the treatment group, which was fed the basal diet supplemented with an additional 1.0 g/d of HDMF (n=11, HDMF).

Study on the Carcass Traits, Meat Quality, and Nutritional Attributes of Six Kinds of Jiangxi Local Breeds Cattle.

The purpose of this study is to explore the carcass traits, meat quality, and nutritional attributes of local yellow cattle (Guangfeng, Ji'an, and Jinjiang) and buffalo (Poyanghu, Xiajiang, and Xinfeng mountain) in Jiangxi Province, and compare the differences among different breeds. The results showed that the dressing percentage, net meat percentage, and meat-bone ratio of Jinjiang cattle were highest, and that Jinjiang cattle had the best meat production performance. Regarding meat quality, the pH value of all breeds was at normal level, and no dark-cutting beef was produced.
