关键词： antioxidant status;biochemical characteristics;carcass and meat quality;duck;Magnolol

摘要： Magnolol rich in Magnolia officinalis is a bioactive polyphenolic compound. The aim of this study was to clarify the effects of magnolol additive (MA) on carcass and meat quality, biochemical characteristics and antioxidative capacity of Linwu ducks, by comparing it to that of antibiotic additive (colistin sulphate, CS). A total of 275 49-d-old ducks were randomly assigned to 5 groups with 5 cages of 11 ducks each and fed by the diets supplemented with 0, 100, 200 and 300 mg of MA/kg and 30 mg of CS/kg for 3 weeks, respectively. The results revealed that MA administration not only increased dressed percentage (calculated as a percentage of live weight), percentage of breast muscle, leg muscle and lean meat (calculated as a percentage of eviscerated weight), but also remarkably increased a*45 min and pH45 min of leg muscle. Moreover, MA administration decreased the percentage of abdominal fat (calculated as a percentage of eviscerated weight), 45-min cooking loss, water loss rate of leg muscle, 45-min cooking loss and drip loss of breast muscle at 24 hr and 48 hr. Furthermore, MA administration enhanced the activities of superoxide dismutase and catalase in serum or liver, serum total antioxidant capacity and hepatic reduced glutathione concentration significantly, compared with the basal diet or CS group (p < .05). On the other hand, triglyceride, total cholesterol, aspartate aminotransferase, malondialdehyde, protein carbonyl and 8-hydroxy-2'-deoxyguanosine contents in serum and liver were significantly increased in Linwu ducks fed with CS, compared with MA groups (p < .05). Taken together, these data demonstrated that magnolol could effectively improve the carcass and meat quality of Linwu ducks by regulating the in vivo antioxidant status and would be a potential candidate to replace antibiotic.

摘要： This study investigated the effects of breed and age on meat quality, and metabolite profiles of duck breast meat, and the relationship between changes in metabolite profiles and the meat quality. The meat quality and 1H nuclear magnetic resonance (NMR)-based metabolomics of breast meat from Pekin and Linwu ducks at 2 different ages (42 and 72d) was analyzed. The results showed that age exerted a greater effect on the observed meat quality traits of breast meat than breed, and its interaction (breed × age) effect on pH values and yellowness (b*) of duck breast meat was significant. Total of 32 metabolites were detected in breast meat of Pekin and Linwu duck. The difference of metabolite profiles in breast meat between Pekin and Linwu duck at 72 d was greater than that at 42 d, while the effects of age on metabolites of duck meat from both breeds were similar. Anserine, aspartate, and carnosine were the most relevant metabolites of duck breast meat quality, and nicotinamide in duck breast meat was negatively correlated with cooking loss. These results provide an overall perspective for bridging the gap between the breed and age on duck meat quality and metabolome, and improve the understanding of the relationship between metabolites and duck meat quality. © 2020 Elsevier Ltd

关键词： Zhijiang duck;mitochondrial;phylogenetic analyses

摘要： Zhijiang duck (ZJ) is one of the famous indigenous breed of Hunan province in China. The complete mitochondrial genome sequence plays an important role in the accurate determination of phylogenetic relationships among metazoans. It is the first time that the complete mitochondrial genome sequence of the ZJ was reported. The total length of the mtDNA is 16,604 bp. It contains the typical structure, including 22 transfer RNA genes, 2 ribosomal RNA genes, 13 protein-coding genes, and 1 non-coding control region (D-loop region). The overall composition of the mtDNA was estimated to be 29.22% for A, 22.20% for T, 32.82% for C, and 15.77% for G. Phylogenetic analyses using N-J computational algorithms showed that the analyzed 20 Anseriform species are divided into four major clades: Anatinae, Anserinae, Dendrocygninae, and Anseranatidae. In addition, our work confirmed that ZJ and Anas poecilorhyncha have a close genetic relationship with fellow tribal members Linwu duck and Youxian duck. Meanwhile, we also found that ZJ and A. poecilorhyncha have highly similar genetic relationship. This work will provides an important data set for the study in the genetic mechanism of duck in Hunan province.

关键词： antioxidant status;grape seed polyphenols;hormone levels;immunoglobulin;reproductive performance;sow

摘要： The aim of this study was to determine the effects of dietary grape seed polyphenols (GSP) supplementation during the late gestation and lactation period on reproductive performance, antioxidative status in serum, nutrient composition, and Ig content in colostrum of multiparous sows. On day 80 of gestation, a total of 64 sows with similar body condition were allocated to a completely randomized block design with 4 dietary treatments (n = 16 sows per treatment): 1) basal diet (CON, control group); 2) basal diet supplemented with 200 IU/kg vitamin E (200VE, positive control group); 3) basal diet supplemented with 200 mg/kg GSP (200GSP); and 4) basal diet supplemented with 300 mg/kg GSP (300GSP). The trial lasted 56 d until the piglets were weaned on day 21 of lactation. Reproductive performance, parameters of antioxidative status, and levels of progesterone (P4) and estradiol (E2) in serum, nutrient composition, and Ig content in colostrum of sows were determined. The number of dead fetuses was reduced, and farrowing survival was significantly improved in the litters from 300GSP-fed (P < 0.05). Preweaning survivability significantly increased in the litters from sows fed 200GSP and 200VE (P < 0.05). The activity of superoxide dismutase and glutathione peroxidase (GSH-Px) in the serum was significantly increased in sows fed 200GSP and 300GSP (P < 0.05). The activity of GSH-Px in the serum also significantly increased in sows fed 200VE (P < 0.05). Sows fed 300GSP had the greatest levels of P4 and E2 in the serum, which was significantly greater than sows fed 200VE and CON (P < 0.05). No significant differences were found among treatments for the content of solids-not-fat, fat, protein, and lactose in colostrum (P > 0.05). However, sows fed GSP had greater IgM and IgG content in colostrum compared with sows fed 200VE and CON (P < 0.05). In conclusion, dietary GSP supplementation during late gestation and lactation improved the farrowing survival and preweaning survivability, enhanced the antioxidant status and hormone levels in serum, and increased the IgM and IgG content in colostrum of sows.

关键词： Gallus gallus domesticus;Dongan black chicken;mitochondrial;phylogenetic analyses

摘要： Dongan black chicken (Gallus gallus domesticus, DBC) is one of the famous native breed of Hunan province in China. The complete mitochondrial genome sequence plays an important role in the accurate determination of phylogenetic relationships among metazoans. It is the first time that the complete mitochondrial genome sequence of the DBC was reported. The total length of the mtDNA is 16,785 bp, It contains the typical structure, including 22 transfer RNA genes, 2 ribosomal RNA genes, 13 protein-coding genes and 1 non-coding control region (D-loop region). The overall composition of the mtDNA was estimated to be 30.27% for A, 23.78% for T, 32.46% for C, and 13.49% for G. Phylogenetic analyses using N-J computational algorithms showed that the analyzed 21 Galliformes species are divided into four major clades: Phasianidae, Numidiidae, Odontophoridae, and Megapodiidae. In addition, our work confirmed that DBC and Taoyuan chicken (TYC) have a close genetic relationship with fellow tribal members Xuefeng black-boned chicken (XBC) and Huang Lang chicken (HLC). Meanwhile, we also found that DBC and TYC have highly similar genetic relationship. This work will provide an important data set for the study of genetic mechanism of chicken in Hunan province. © 2018, © 2018 The Author(s).

关键词： Carcass trait;Finishing pig;Intramuscular fat;Meat quality;Muscle fiber;Ramie

摘要： This study investigated the effects of ramie (0, 3, 6, 9, or 12%) included in finishing diets on carcass traits and meat quality of Xiangcun black pigs. Results showed that ramie decreased (linear, P <.05) backfat depth while it increased (linear, P <.05) loin-eye area. A quadratic effect of shear force in longissimus thoracis (LT) was observed, and the lowest value was noted in the 6% ramie group. Protein content in LT was linearly increased by ramie (linear, P <.01). Meanwhile, dietary ramie linearly decreased lipogenic genes mRNA levels and fiber cross-sectional area, but it linearly increased total fiber number of LT. These results suggest that ramie included in the diet <9% is an effective feed crop to partly improve carcass trait and muscle chemical composition without negatively affecting growth performance, and the underlying mechanism may be due to the changed lipogenic potential and myofiber characteristics induced by ramie. © 2018

关键词： metabolite profiling;duck meat;multivariate data analysis;nuclear magnetic resonance

摘要： In an effort to further understand of the differences of meat flavor and texture between Linwu ducks and Pekin ducks at market age, we investigated the meat metabolite composition of the two breeds of ducks using 600 MHz 1H nuclear magnetic resonance (NMR) spectroscopy. Comprehensive multivariate data analysis including principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA), and orthogonal projection to latent structure-discriminant analysis (OPLS-DA) were applied to analyze the 1H-NMR profiling data to identify the distinguishing metabolites of breast meat between two breeds of ducks. Compared with 42-d-old Pekin duck meat, breast from 72-d-old Linwu duck has higher concentration of anserine, carnosine, homocarnosine, and nicotinamide, but significantly lower concentration of succinate, creatine, and myo-inositol. These results contribute to a better understanding of the differences in meat metabolite composition between 72-d-old Linwu and 42-d-old Pekin ducks, which could be used to help assess the quality of duck meat as a food. © 2016 Poultry Science Association Inc.

关键词： Magnolol;Linwu duck;Growth performance;Antioxidant-related gene expression;Intestinal mucosal status

摘要： Magnolol rich in Magnolia officinalis is a bioactive polyphenolic compound. The aim of this study was to examine the effects of magnolol additive (MA) on growth performance, expression levels of antioxidant-related genes, and intestinal mucosal morphology of Linwu ducks aged from 49 to 70 days, comparing with that of an antibiotic additive (colistin sulfate [CS]). A total of 275, 49-day-old ducks were assigned to 5 groups with 5 cages of 11 ducks each and fed diets supplemented with 0, 100, 200 and 300 mg of MA/kg and 300 mg of CS/kg for 3 weeks, respectively. The results showed that the average daily body weight gain (ADG) was increased significantly in MA-fed groups (200 and 300 mg/kg), compared with the basal diet (BD) group (P < 0.05). The mRNA levels of superoxide dismutase-1 (SOD1), manganese superoxide dismutase-2 (MnSOD2) and catalase (CAT) were also increased significantly in MA groups (P < 0.05). In addition, hematoxylin and eosin staining revealed that Linwu ducks fed the diets with MA had more intact intestinal mucosa than those fed the BD and CS diets. In addition, ileal villus height, ileal villus height/crypt depth ratio (V/C) and duodenal V/C were also improved significantly (P < 0.05). Taken together, these data demonstrated that MA is an effective feed additive to enhance the growth performance of the Linwu ducks by improving the antioxidant and intestinal mucosal status, suggesting that MA will be a potential additive to replace antibiotic (CS). © 2017 Chinese Association of Animal Science and Veterinary Medicine

关键词： Youxian Sheldrake;Phytase;Apparent Nutrient Digestibility;Performance;Apparent Ileal Amino Acid

摘要： Objective: This study investigated the effect of microbial phytase supplementation on growth performance, tibia ash, plasma parameters, apparent ileal digestibility (AID) of amino acid (AA) and apparent digestibility of nutrients in Youxian Sheldrakes fed with low-phosphorus (P) corn-soybean diets. Methods: A total of 350 Youxian Sheldrakes (7d old) were randomly divided into 5 treatment groups: positive control (PC) group has adequate available P diet (0.42% and 0.38%, starter and grower), negative control (NC) group were deficient in available P (0.32% and 0.28%, starter and grower) and NC diet was supplemented with 3 levels of microbial phytase (500, 750, and 1,000 U/kg). Results: Dietary supplementation of phytase in NC diet improved the average daily gain, increased the levels of serum calcium (Ca), tibia Ca and P, AID of AA and apparent digestibility of energy and Ca in starter stage (p<0.05). There was an increased (p<0.001) in the utilization of P from 17.3% to 23.9%. Phytase supplementation (1,000 U/kg) has shown that the AID of His, Thr, Val, indispensable AA, Glu, Pro, and dispensable AA was higher (p<0.05) than that of NC. Moreover, phytase supplementation improved (p<0.05) serum and tibia Ca and P, AID of AA and apparent digestibility of dry matter, crude protein, energy, P and Ca, and reduced (p<0.05) feed to gain ratio (F/G) and the levels of serum alkaline phosphatase in grower stage. Likewise, an increase (p<0.001) in the utilization of P was noticed from 12.6% to 17.2%. Supplement phytase at 750 U/kg improved the AID of His, Thr, Asp, Cys, Pro, and Ser (p<0.05). Conclusion: The microbial phytase supplement could improve growth performance, AID of some AA and apparent utilization of other nutrients in Youxian Sheldrakes, and reduce excreta P load to environment.

关键词： α-半乳糖苷酶;屠宰性能;血清生化指标;血清激素指标;爱拔益加肉鸡

摘要： 为研究饲粮添加不同水平α-半乳糖苷酶对爱拔益加(AA)肉鸡屠宰性能、血清生化、激素指标的影响,试验选择1日龄体重相近的健康AA肉鸡360羽,随机分成6个处理,处理A饲喂玉米-豆粕型基础饲粮(正对照处理),处理B在基础饲粮水平上降低代谢能0.21MJ/kg(负对照处理),处理C、处理D、处理E、处理F分别在负对照处理基础上添加75 mg/kg、150 mg/kg、300mg/kg、600 mg/kg的α-半乳糖苷酶制剂.结果表明:(1)处理E较其它各处理有提高21日龄试鸡胸肌率、瘦肉率及降低腹脂率的趋势;处理D较正、负对照处理对42日龄AA肉鸡胸肌率有明显提高作用(P＜0.05),同时处理D较正对照处理对42日龄试鸡瘦肉率有明显改善作用(P＜0.05).(2)饲粮中添加α-半乳糖苷酶对42日龄AA肉鸡血清球蛋白含量影响显著(P＜0.05),以处理F最高.(3)处理F试鸡42日龄血清胰岛素含量显著高于处理A、处理B、处理C和处理D(P＜0.05),同时处理F试鸡42日龄血清T3含量及T3/T4均显著高于负对照处理和处理E(P＜0.05),而与处理D差异不显著(P＞0.05).因此,本试验条件下AA肉鸡生长前期(1～21日龄)在基础饲粮降低0.21MJ/kg代谢能的基础上,添加75 mg/kg的α-半乳糖苷酶制剂即可达到与饲喂基础饲粮试鸡相当甚至稍优的效果;在试鸡生长后期(22～42日龄)在基础饲粮降低0.21MJ/kg代谢能的基础上,添加150 mg/kg的α-半乳糖苷酶制剂较适宜.

关键词： 硒;亚硒酸钠;酵母硒;抗氧化能力;蛋;临武鸭

摘要： 本试验旨在研究酵母硒和亚硒酸钠对临武鸭血清抗氧化能力、蛋品质及蛋硒存留动态变化的影响。试验选用29周龄产蛋率接近的健康临武鸭240只,随机分为3组,每组5个重复,每个重复16只。对照组饲喂基础饲粮(不补充外源硒,硒含量为0.183 mg/ kg);试验组在基础饲粮中分别补充0.3 mg/ kg亚硒酸钠或酵母硒,饲喂42 d后,撤除外源硒,连续饲喂基础饲粮10 d。结果表明:1)与对照组相比,饲粮中补充亚硒酸钠或酵母硒对临武鸭生产性能和蛋品质无显著影响(P>0.05),饲粮补充0.3 mg/ kg亚硒酸钠或酵母硒极显著提高了临武鸭血清中硒含量(P<0.01),显著提高了血清谷胱甘肽过氧化物酶活性(P<0.05);饲粮补充0.3 mg/ kg酵母硒显著降低了血清中丙二醛含量(P<0.05)。2)与对照组相比,饲粮中补充亚硒酸钠或酵母硒极显著提高了蛋硒含量(P<0.01);停止补充后的5 d内,试验组蛋硒含量仍极显著高于对照组(P<0.01);停止补充后的7、8 d,酵母硒组蛋硒含量极显著高于亚硒酸钠组和对照组(P<0.01);停止补充后的9、10 d,试验组蛋硒含量衰减至对照组相同水平(P>0.05)。由此可见,饲粮中补充亚硒酸钠或酵母硒对临武鸭生产性能和蛋品质无显著影响,但能改善临武鸭血清抗氧化能力,提高血清和蛋中硒含量;与亚硒酸钠相比,饲粮补充酵母硒可延长硒在蛋中的存留时效。

关键词： *Anser cygnoides;*mitochondrial DNA;*phylogenetic analyses

摘要： In this study, we cloned and sequenced the complete mitochondrial DNAs of Chinese goose, Anser cygnoides populations from three different areas of Hunan province in China. The Anser cygnoides breed Wugangtong white goose (WGTW) sample and Wugangtong grey goose sample (WGTG) were taken from the Wugang county of Shaoyang city, the Anser cygnoides breed Xupu goose (XP) sample was taken from the Xupu county of Huaihua city, and the Anser cygnoides breed Yanling white goose (YLW) sample was taken from the Yanling county of Zhuzhou city. The organization of the four Anser cygnoides breeds mitochondrial genomes was similar. Phylogenetic analyses using N-J computational algorithms showed that the analyzed species are divided into four major clades: Anatinae, Anserinae, Dendrocygninae and Anseranatidae. It was noted that Wugangtong white goose, Yanling white goose and Xupu goose have highly similar phylogenetic relationship.
