摘要：
Long chain PUFA contents in plasma and liver both exhibited diurnal rhythms in pigs. However, whether mRNA expression of amino acid transporter and circadian gene Cry in intestinal mucosa is also rhythmic is yet to be known. The purpose of this study aims to investigate the diurnal rhythm in mRNA expression of genes encoding amino acid transporter and whether their rhythm was related to the expression of circadian gene Cry in intestinal mucosa of piglets. Thirty-six piglets (DurocxLandracexLarge Yorkshire) at the age of 35 days were selected and fed for three weeks, and then samples were collected at 3:00 am (Clo3), 7:00 am (Clo7), 11:00 am (Clo11), 3:00pm (Clo15), 7:00pm (Clo19), and 11:00pm (Clo23) at the age of 56 days. At each time point, small intestinal mucosa samples were collected from duodenum, jejunum, and ileum for detection of mRNA expression of the amino acid transporters and circadian gene Cry. The results showed that mRNA expression of most amino acid transporters in intestinal mucosa was higher at night and lower during the daytime. Expression of SLC1A2, SLC6A20, SLC7A1, and SLC6A14 in duodenal mucosa reached the peak at Clo3 and Clo7; the diurnal rhythm of expression of SLC1A2, SLC6A20, and SLC7A1 was similar to Cry1, while the diurnal rhythm of expression of SLC6A14 had a similar trend to Cry2. Expression of SLC16A10, SLC1A2, and SLC7A1 in jejunal mucosa reached the peak at Clo7, while SLC6A14 reached the peak at Clo3; the diurnal rhythm of expression of SLC1A2 showed a similarity with Cry1, while the diurnal rhythm of expression of SLC16A10, SLC7A1, and SLC6A14 was similar to Cry2. Expression of SLC6A14, SLC6A20, and SLC7A1 in ileal mucosa reached the peak at Clo3; the diurnal rhythm of expression of SLC6A20 has a similarity with Cry1, while the diurnal rhythm of expression of SLC7A1 and SLC6A14 was similar to Cry2. The results suggested that the mRNA expression of most genes encoding amino acid transporters exhibited diurnal rhythms in the intestinal mucosa of piglets, and SLC7A1, SLC6A14, and SLC1A2 have a similar rhythm with circadian clock genes Cry1 and 2, and they reached the peak at Clo3 and Clo7.

摘要：
A 60-days feeding trial was conducted to determine the effect of dietary supplementation of Lonicera macranthoides leaf (LML) on growth performance, meat quality, and free amino acid profiles in growing-finishing pigs. L. macranthoides leaves were harvested, air-dried and milled to powder. A total of 288 crossbred barrows (Large White × Landrace) with an average initial BW of 54.0 ± 3.4 kg were randomly allocated to 3 treatment groups and fed either a basal diet or a diet supplemented with 0.5% or 1.0% LML powder. Results showed that diet supplemented with LML powder did not affect average daily feed intake (ADFI) and feed: gain ratio (P > 0.05) in growing-finishing pigs. Moreover, diet supplemented with LML powder showed no significant effects on carcass traits (P > 0.05) including dressing percentage, backfat thickness and loin muscle area, and meat quality traits (P > 0.05) including meat color, intramuscular fat and cooking loss. However, diet supplemented with LML powder significantly improved free amino acid profiles in serum and longissimus thoracis muscle in growing-finishing pigs. Most importantly, dietary LML powder increased total free amino acids content (P < 0.001) and essential free amino acid content (P < 0.001) in longissimus thoracis muscle. These results indicate that LML has the potential to improve the nutritional value of meat through improving free amino acid profiles. © 2016 Chinese Association of Animal Science and Veterinary Medicine

摘要：
The effects of dietary supplementation with lysine-yielding Bacillus subtilis on gut morphology, cecal microflora, and expression of intestinal cytokine mRNA of Linwu ducks (a Chinese local domesticated duck) were investigated after a 63-d feeding trial. Two hundred forty 1-d-old female ducklings were randomly assigned to 1 of 4 dietary treatments, and there were 60 birds per treatment replicated 6 times with 10 birds each. The experimental diets consisted of a basal diet containing no antibiotic or growth promoters, the basal diet supplemented with 150 mg Aureomycin per kg feed, and 2 others supplemented with 5.0 × 108 and 5.0 × 1010 cfu B. subtilis/kg feed, respectively. Birds fed the diets supplemented with B. subtilis had increased (P < 0.001) villi height in the jejunum and ileum and reduced (P < 0.001) crypt depth in the jejunum compared with birds fed the control diet. Greatest (P < 0.01) villus height:crypt depth ratio was obtained with the jejunum and ileum of birds fed the diet supplemented with 5.0 × 1010 cfu B. subtilis/kg feed. Dietary supplementation with B. subtilis resulted in increased (P < 0.05) cecal counts of Megasphaera elsdenii. Greater cecal Lactobacillus counts were obtained in ducks fed the diets supplemented with Aureomycin and B. subtilis. Ducks fed the diets supplemented with B. subtilis showed suppressed (P < 0.001) expression of interleukin (IL)-1β, IL-2, and IL-10 in their jejunum. When compared with the control, the expression of interferon (IFN)-γ in the jejunum of ducks fed the diet supplemented with 5.0 × 108 cfu B. subtilis/kg feed was significantly increased (P < 0.05). Dietary supplementation with B. subtilis or Aureomycin reduced (P < 0.001) ileal expression of IL-10. When compared with the control, the expression of IL-2 and IL-8 in the ileum of ducks fed the diet supplemented with 5.0 × 1010 cfu B. subtilis/kg feed showed a significant decrease (P < 0.05). In conclusion, dietary supplementation with lysine-yielding B. subtilis improved gut morphology, increased the population of beneficial gut microflora, and stimulated increased intestinal immune response of Linwu ducks. © 2015 American Society of Animal Science.

摘要：
本研究通过分离猪卵巢中中等卵泡的颗粒细胞,以不同浓度的大豆苷元进行处理,并通过检测细胞培养基中固醇激素的水平及细胞中固醇激素合成关键基因的表达水平,来探讨大豆苷元对体外培养的猪颗粒细胞固醇激素合成的影响及其机制.结果发现,高浓度的大豆苷元会显著降低(P＜0.05)颗粒细胞活力.同时,不同浓度的大豆苷元均不影响(P＞0.05)颗粒细胞培养基中E2和P4的水平,但是均显著抑制了(P＜0.05)颗粒细胞中ER-beta和3-beta HSD的表达水平,且1和10μmol/L的大豆苷元还显著抑制了(P＜0.05)颗粒细胞中CYP19A1的表达水平.结果表明,在含有血清的培养基中加入大豆苷元,不影响E2和P4的分泌,但抑制了固醇激素合成关键基因的表达和ER-beta的表达,且其作用机制还有待进一步研究.

摘要：
Soy isoflavones have been shown to affect lipid metabolism, however the underlying molecular mechanism(s) have not yet been fully understood. The present study, using female Bama mini-pig as a model, examined the effects of soy isoflavones on lipid metabolism and involved gene expression in different white adipose tissues. Female Bama Xiang mini-pigs of 35 days old were fed a basal diet (control, Con), or basal diet supplemented with increasing amounts of soy isoflavones (250, 500, or 1250 mg/kg diet) for 120 days. The results showed that soy isoflavones did not affect the body weight, but decreased the dorsal subcutaneous adipose tissue (DSA) mass and increased the mass of abdominal subcutaneous adipose tissue (ASA) and perirenal adipose tissue (PRA). Besides, soy isoflavones decreased the expression of lipogenic genes and increased the expression of lipolytic genes in DSA, while the opposite effects were observed in ASA and PRA. In addition, the expression of lipoprotein lipase was down regulated in DSA while up regulated in ASA and PRA by soy isoflavones. Moreover, the expression of estrogen receptors (ERs) was up regulated in DSA, and down regulated in ASA and PRA by soy isoflavones. Our results suggest that soy isoflavones affected the lipid metabolism in white adipose tissues of Bama mini-pigs in a site-specific manner, which might be mediated through PPARs and ERs regulated gene expression. © 2015 Elsevier Inc.

摘要：
This study measured gaseous emissions, growth performance and pork quality in a deep-litter system and concrete-floor system. Three hundred and twenty weaned piglets with an average body weight (BW) of 6.0±0.3kg were assigned randomly into three treatments. Treatments 1 and 2 included four pens with 20 pigs for each pen respectively in the deep-litter system, and the ratio of sawdust to chaff was 5:5 and 3:7 for treatments 1 and 2 respectively, the probiotics inoculated into the fermentation bedding for both treatments were composed of Saccharomycetes, Bacillus subtilis and Actinomycetes; treatment 3 was the conventional concrete-floor system including eight pens with 20 pigs for each pen. The concentration of NH3 and CO2 in the deep-litter system was significantly (P<0.001) lower than that in the concrete-floor system. The ratio of feed to gain for pigs raised in the deep-litter system was significantly (P<0.05) lower than that for pigs housed in the concrete-floor system. The carcass weight and length, color score and rate of cooking meat for pork from the deep-litter system were significantly (P<0.05) higher than those from the concrete-floor system. Results indicate that pigs raised in the deep-litter system had some animal welfare improvements and an odor nuisance reduction; in the meantime, pork quality also improved from the deep-litter system compared to the pigs housed in the concrete-floor system. © 2014 Japanese Society of Animal Science.

摘要：
利用体外产气法研究不同能量水平与不同加工方式玉米对瘤胃体外发酵参数的影响。试验以玉米秸秆为主要粗饲料来源设计精粗比为65∶35的等氮饲粮，选用玉米青贮与过瘤胃脂肪调整低、高能量水平，普通玉米与蒸汽压片玉米作为不同加工方式，采用2×2因子试验设计。结果表明，高能水平饲粮的理论最大产气量、48 h 总产气量、干物质降解率均显著高于低能（P ＜0．05），普通玉米高能组的乙酸、丙酸含量显著高于低能组（P ＜0．05）。同一能量水平下，蒸汽压片处理组的48 h 总产气量均显著高于普通玉米组（P ＜0．05）；而低能条件下蒸汽压片组的总挥发酸、丙酸含量显著高于普通玉米组（P ＜0．05）。不同饲粮营养水平与体外产气参数相关性分析表明48 h 总产气量与中性洗涤纤维（NDF）呈显著负相关（P ＜0．05），与中性洗涤可溶物（NDS）、非纤维性碳水化合物（NFC）和NDS／CP 呈显著正相关（P ＜0．05）。因此，使用蒸汽压片方式处理玉米以及提高饲粮能量水平均可以显著增加体外发酵48 h 总产气量；低能水平下，蒸汽压片玉米对改善瘤胃的发酵特性更为明显。

摘要：
本试验旨在选出最佳单一菌株且确定其混合菌比例和发酵路线,再运用正交试验对混合菌固态发酵红薯渣工艺进行条件优化,以达到提高产物粗蛋白质含量的目的。首先采用4株酵母菌,4株黑曲霉菌,5株枯草芽孢杆菌,1株乳酸菌,在相同发酵条件下固态发酵红薯渣,以产物粗蛋白质含量为主要衡量目标,进行单一菌株的筛选;再利用筛选出的4株最佳单菌进行发酵路线选择;最后对选出的发酵工艺以发酵时间、发酵温度、氮源添加量和菌液接种量4个因素为变量进行L_(16)(4~4)正交试验,通过测定产物粗蛋白质含量,确定最佳发酵条件。结果表明,产朊假丝酵母、黑曲霉41126、枯草芽孢杆菌Y111、乳酸菌为最佳单一菌株;混合菌比例为(黑曲霉41126∶产朊假丝酵母=2∶1)+(产朊假丝酵母∶枯草芽孢杆菌∶乳酸菌=1∶1∶1)的二次发酵路线产物粗蛋白质含量最高,为15.11%;最佳发酵条件为:发酵时间3 d,发酵温度28 ℃,氮源添加量1%,菌液接种量3%。此发酵条件下,产物粗蛋白质含量达12.35%,较同等氮源添加量原料发酵前提升了85.99%,且产物能量值和氨基酸含量都有了不同程度的提升,尤其几种必需氨基酸含量明显上升。

摘要：
为研究高粱和小麦替代玉米对PIC生长猪生产性能的影响,试验1和试验2分别选取约27和31 kg的PIC生长猪30头,随机均分为A、B、C3组,每组10个重复.试验日粮为颗粒饲料,试验1:A组(对照)饲喂玉米-豆粕型日粮,B、C两组分别利用高粱替代A料中全部和30％比例的玉米;试验2:A组(对照)饲喂玉米-豆粕型日粮,B、C组分别利用小麦替代A料中全部和30％比例的玉米.结果表明,试验1中,A组平均日采食量和平均日增重均最高,较B、C两组分别提高13.77％(P＜0.05)、2.61％(P＞0.05)和12.50％(P＞0.05)、14.08％(P＞0.05),A组的料肉比较B、C2组分别降低1.52％(P＞0.05)和10.60％(P＜0.01);试验2中,B组的平均日采食量和平均日增重较A组分别提高10.44％(P＞0.05)和1.11％(P＞0.05),而料肉比较A组提高了10.45％ (P＜0.05),C组平均日增重较A组降低4.44％ (P＞0.05),料肉比降低0.50％ (P＞0.05).结果表明,高粱替代日粮中全部或30％的玉米会对生长猪的生产性能产生一定的负面影响,而小麦以30％的比例替代玉米在性价比方面存在一定优势.

摘要：
This study was to investigate the effect of soyabean isoflavones (SIF) on onset of puberty, serum hormone concentration, and gene expression in hypothalamus, pituitary and ovary of female Bama miniature pigs. Fifty five, 35-days old pigs were randomly assigned into 5 treatment groups consisting of 11 pigs per treatment. Results showed that dietary supplementation of varying dosage (0, 250, 500, and 1,250 mg/kg) of SIF induced puberty delay of the pigs with the age of puberty of pigs fed basal diet supplemented with 1,250 mg/kg SIF was significantly higher (p<0.05) compared to control. Supplementation of SIF or estradiol valerate (EV) reduced (p<0.05) serum gonadotrophin releasing hormone and luteinizing hormone concentration, but increased folliclestimulating hormone concentration in pigs at 4 months of age. The expression of KiSS-1 metastasis-suppressor (KISS1), steroidogenic acute regulatory protein (StAR) and 3-beta-hydroxysteroid dehydrogenase/delta-5-delta-4 isomerase (3β-HSD) was reduced (p<0.01) in SIF-supplemented groups. Expression of gonadotropin-releasing hormone receptor in the pituitary of miniature pigs was reduced (p<0.05) compared to the control when exposed to 250, 1,250 mg/kg SIF and EV. Pigs on 250 mg/kg SIF and EV also showed reduced (p<0.05) expression of cytochrome P450 19A1 compared to the control. Our results indicated that dietary supplementation of SIF induced puberty delay, which may be due to down-regulation of key genes that play vital roles in the synthesis of steroid hormones.
