Plant polyphenols have promoting health features, including anti-mutagenic, anti-inflammatory, anti-thrombotic, anti-atherogenic, and anti-allergic effects. These polyphenols improve the immune system by affecting the white blood cell proliferation, as well as by the synthesis of cytokines and other factors, which contribute to immunological resistance. Olive trees are one of the most famous trees in the world. Whereas, olive olive oil and derivatives represent a large group of feeding resource for farm animals. In recent years, remarkable studies have been carried out to show the possible use of olive oil and derivatives for improvement of both animal performance and product quality. In vivo application of olive oil and its derived products has shown to maintain oxidative balance owing to its polyphenolic content. Consumption of extra virgin olive oil reduces the inflammation, limits the risk of liver damage, and prevents the progression of steatohepatitis through its potent antioxidant activities. Also, the monounsaturated fatty acids content of olive oil (particularly oleic acid), might have positive impacts on lipid peroxidation and hepatic protection. Therefore, this review article aims to highlight the nutritional applications and beneficial health aspects of olive oil and its effect on poultry production.

Xupu goose is one of the famous native breed in China. In this work we reported the complete mitochondrial genome sequence of the Xupu goose in Hunan Province for the first time. The total length of the mitogenome is 16,742 bp, with the base composition of 30.21% for A, 22.70% for T, 32.02% for C, 15.08% for G, in the order C > A > T > G feature occurring in the Xupu goose. And it is made up of two ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes and a non-coding control region (D-loop region). The characteristics of the mitochondrial genome were analyzed and discussed in detail. The complete mitochondrial genome sequence of Xupu goose will be useful for the phylogenetics of poultry, and be available as basic data for the genetics and breeding.

This study investigated the effects of fermented ramie feed (FRF) on the growth performance, serum biochemistry, metabolic capacity, antioxidant capacity, and intestinal health of Linwu ducks. A total of 480 female Linwu ducks (age: 28 days) were randomly divided into five treatments (six replicates per group; 16 ducks per replicate). The control group received a basal diet and the treatment groups received the basal diet supplemented with by 3%, 6%, 9% or 12% FRF. The experiment lasted 21 days. Notably, 3% and 6% FRF trended to increase the final body weight (P = 0.097) and significantly increased the thymus index (P < 0.05). Regarding serum indices, FRF greatly reduced the triglyceride and glucose contents, and increased the catalase and glutathione peroxidase activities (P < 0.05). Besides, FRF significantly increased the apparent metabolic rates of dry matter, crude protein, crude ash and gross energy (P < 0.05). Furthermore, FRF remarkably improved villus height in the duodenum. FRF also increased the relative abundances of beneficial bacteria (Alistipes and Barnesiella) and reduced the relative abundances of harmful parasitic bacteria (Desulfovibrio and Enterenecus) in the cecum (P < 0.05). Thus, partial FRF substitution greatly improved serum biochemistry, antioxidant capacity, metabolic capacity and intestinal health in Linwu ducks, thereby enhancing the growth performance to a certain extent. The optimal level of FRF substitution is 3%−6% according to the impacts of growth performance and overall health.

Swan goose breed Daozhou ( Anser cygnoidesLinnaeus, 1758 breed Daozhou, DZ) is one of the famous native breed of Hunan Province in China. The complete mitochondrial genome sequence plays an...

Duck breed Longshengcui (Anas platyrhynchos Linnaeus, 1758 breed Longshengcui, LSC) is one of the famous native breed of the Guangxi Zhuang Nationality Autonomous Region in China. In this study, we report the complete mitochondrial genome of LSC. The mitogenome (GenBank accession no. MZ895120) has 16,602 bp in length and consisted of the well-known 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and the control region. The phylogenetic analysis showed that LSC and Zhijiang duck have highly similar genetic relationship. These results are helpful for the conservation of genetic resources and phylogeny of this species.

Wugangtong white goose is one of the famous native breed in Hunan province of China. In this study, the complete mitochondrial genome sequence of the Wugangtong white goose was reported in Hunan Province first, which was determined through PCR-based method. The total length of the mitogenome is 16,741 bp. It contains the typical structure, including 2 ribosomal RNA genes, 22 transfer RNA genes, 13 protein-coding genes and 1 non-coding control region (D-loop region) as that of most other vertebrates. The overall composition of the mitogenome was estimated to be 30.22% for A, 22.69% for T, 32.02% for C and 15.06% for G. All the protein initiation codons are ATG, except for COX1, COX2 and ND5 are GTG, ND6 is CTA. The complete mitochondrial genome sequence of the Wugangtong white goose will provide an important data set for the study in genetic mechanism of Wugangtong goose in Hunan province.
