| Abstract:Two experiments were carried out to investigate the effects of bioefficacy of DL-2-Hydroxy-4-Methylthio-Butanoic Acid (HMTBA) for layers fed on medium or low nutrient level diets under restricted feeding (Exp.1) or ad libitum feeding (Exp.2) on egg production and quality. In Exp.1, a total of 2000 layers were assigned to 10 treatments in a completely randomized design, with 10 replicates per treatment, whilst in Exp.2 there were 10 replicates (15 hens per replicate) of 10 treatments. In all experiments, the bioefficacy of HMTBA was set at 80%, 84%, and 88% (on weight basis). In Exp.1, Methionine deficiency significantly (P < 0.05) reduced egg weight and eggshell weight regardless of the dietary nutrient level. Bioefficacy of HMTBA had no influence (P > 0.05) on any egg production or egg quality parameters of hens when compared with DL-methionine (DLM) treatments. In Exp.2, egg production, ADFI, egg weight, egg mass and feed conversion ratio significantly declined due to methionine deficiency (P < 0.01). There was no difference (P > 0.05) between HMTBA and DLM on egg production and egg quality parameters within each dietary nutrient level. In conclusion, bioefficacy of HMTBA can be set at 88% on weight basis regardless of dietary nutrient level. | |||

| Abstract:The study was carried out to investigate the effects of methionine source and level on hepatic methionine and lipid metabolism of commercial laying hens fed with low nutrient level (LN) or moderate nutrient level (MN) diets under restricted feeding. A completely randomized design was used. Within each nutrient level, there were 2 methionine sources (DL-methionine, DLM; DL-2-hydroxyl-4-methylthio-butiric acid, HMTBA) and 3 supplementation levels (LN: 0, 0.091 and 1%; MN: 0, 0.113 and 1%). A total of 2000 layers was allocated to 10 dietary treatments with 10 replicates for each. For hens fed LN diets: regardless of nutrient level, methionine source and level had no effects on concentration of Hcy in liver or plasma; hens treated with DLM had higher plasma Met and Tau concentration than those treated with HMTBA; when compared with the control group, adding methionine (HMTBA source) at 0.091% or 1% markedly increased the expression of GNMT; adding methionine (DLM source) at 1% significantly increased the expression of BHMT. Under the condition of feeding MN diets: plasma Met concentration significantly increased with methionine supplementation. Adding methionine (HMTBA source) at 0.113% or 1% significantly increased the expression of ADA and adding methionine (HMTBA source) at 0.113% significantly increased the expression of MS. When control diet was fed, hens fed LN diets had higher expression of BHMT and MS. When adding methionine (HMTBA source) at 1%, hens fed LN diets had higher expression of SAHH, MTHFR, CEBPβ, AdipoR2, INF-α and IL-1β. When adding methionine (DLM source) at 1%, feeding LN diet significantly increased the expression of TNF-α. In conclusion, methionine deficiency may increase the methionine regeneration by up-regulating the expression of genes involved in hepatic methionine metabolism. Under the condition of adding excess HMTBA, feeding low-nutrient diet may increase the folate-dependent pathway of methionine regeneration, SAMe-dependent transmethylation, fat synthesis and inflammatory cytokines in liver, and increase the potential risk of liver diseases. | |||

| Abstract:The relative bio-efficacy (RBE) of DL-methionine (DLM) and DL-methionine hydroxy analogue calcium salt (MHA-Ca) compared to L-Met was evaluated in this paper. A total of 2560 10-d-old Ross 308 male broilers were randomly allotted to 16 treatments with 8 replicates of 20 birds each.Birds were fed with either a corn-soybean meal-pea protein concentrate-based diet (Met：0.28,10-21d；0.26,22-42d with no methionine and cysteine supplementation), or methionine supplemented diets at0.03, 0.06, 0.10, 0.15, and 0.21% methionine from L-Met, or DLM, or MHA-Ca from 10 to 42 days of age based on the Met content (L-Met or DL-Met) or equal mass to MHA.The average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) in the period of 10 to 42 days were measured. Liver (at 42d) was collected to determine the redox state:H2O2, catalase (CAT), malondialdehyde (MDA), total glutathione (T-GSH), oxidized GSH (GSSG), reduced GSH (reGSH) and 8-hydroxyguanosine (8-OHDG). Supplement of Met elicited linear or quadratic improvements on ADG, ADFI and FCR with no different among the Met sources except FCR (P=0.0251, L-Met and DLM was better than MHA-Ca). The effect on carcass performance was similar to growth performance. Based on equal mass, the RBE of DLMand MHA-Ca to L-Met was 115.4and 87.6%,respectively based on ADG; 94.6 and 48.6%, respectively, based on FCR; 119.8% and 91.2%, respectively, based on breast weight; 107.4% and 79.5%, respectively, based on breast meat yield. The supplementation of methionine (regardless of source) increased the levelsof GSH (P<0.0001) and decreased the level of MDA(P<0.0001), CAT (P<0.0001) and 8-OHDG (P=0.0035) in broiler livers. Inconclusion, the RBE of DLM and MHA-Ca was 108% and 64% on a product base. MHA-Ca tended to have an advantage on anti-oxidative system which may partly compensate for the low efficiency on protein synthesis, while the relation between anti-oxidative ability and RBE needed further study. | |||

| Abstract:To investigate the effect of different methionine sources on lipid deposit and lipid metabolism related genes expression in the liver of broilers during different growth phase, two trails was conducted. A total of 1200 1-day-old male Ross 308 broiler chicks with similar body weight were randomly selected and allotted to 10 treatments with 6 replications of 20 birds in trail 1. Birds were fed with either a corn-soybean meal-pea protein concentrate-based diet (Met：0.28, 1-21d with no methionine and cysteine supplementation), or methionine supplemented diets at 0.10, 0.22 and 0.32% from L-methionine (LM), DL-methionine (DLM)or methionine hydroxyl analogue calcium Salt (MHA-Ca) from 1-21d based on the Met content (LM or DLM) or equal mass to MHA. In trail 2, a total of 2112 21-day-old chicks were randomly allotted to 12 treatments with 8 replications of 22 birds each. Birds were fed with methionine supplemented diets at 0.05, 0.10, 0.14 and 0.24% from LM, DLM or MHA-Ca from 22-42d. A treatment fed with a basal diet (Met: 0.28, 1-21d; 0.26%: 22-42d) from 1-42d was set as negative control. Met deficiency significantly increased liver EE in broilers during 1-21d (P<0.0001) and Met excess increased that during 22-42d (P<0.0001). Chickens fed LM supplemental diets had the highest liver EE and MHA-Ca the lowest regardless of growth phase (P<0.0001).Met level had a significant effect on adiponectin receptor2 (ADIPOR2), acyl-coenzyme A oxidase 1 (ACOX1), carnitine palmitoyltransferase (CPT1A), carbohydrate response element-binding protein (CHREBP), fatty acid synthase (FASN) and apolipoprotein (APOB) expression during 22-42d (P<0.05) while only affected ACOX1, CPT1Aand CHREBP expression during 1-21d (P<0.05). There was a difference on CPT1A(P=0.010) and CHREBP (P=0.007) expression among Met sources during 1-21d and the expression of CHREBP(P=0.009), FASN (P=0.014) and APOB (P=0.002) existed difference during 22-42d. In conclusion, Met deficiency and excess may increase liver lipid accumulation by suppressing lipid catabolism and transport related gene expression in broilers and MHA-Ca showed a good benefit for fatty liver. | |||

| Abstract:Previous studies have indicated that monochromatic green light-emitting diodes (LED) light stimuli during embryogenesis accelerated post-hatch pectoral muscle growth of broilers. In this study, we further investigated the potential mechanism of this phenomenon by determine the gene expression of paired box genes, myogenic regulatory factors and the key factors of Wnt/β-catenin signaling pathway in the pectoral muscle of embryos and neonatal broilers incubated in dark condition or green LED light stimulation. Arbor Acres fertile broiler eggs (n = 200) were randomly assigned to 2 incubation groups and exposed to continuous green light, or a dark condition (control) from the first day to 19 d of incubation. The light sourced from LED lamps with the intensity of 30 lx at eggshell level. The results showed that green LED light stimuli during embryogenesis increased the total pectorals muscle weight on days H3 and H7, and relative pectorals muscle weight of newly hatched chicks on day H7 (P < 0.05) in comparison to the dark condition. The expression of Pax3 on days E15 (P < 0.05) and E17 (P < 0.01), Pax7 on days E19 and H1 (P < 0.05), MyoD on days E19 and H1(P < 0.05), MyoG on day H1 (P < 0.05), and Myf5 from days E17 to H1 (P < 0.05) was higher in green light group than those in dark condition. In addition, although the no significant difference on Wnt11 mRNA expression was found between treatments, the green LED light stimuli upregulated the mRNA expression of Wnt3a form days E15 to E19, and β-catenin on day E19 (P < 0.05). These results suggest that providing 30 lx green LED light stimuli from the first day to 19 d of incubation may accelerate pectoral muscle growth in embryos and neonatal broilers by enhancing myoblast proliferation and differentiation in the late embryonic stage of embryos and neonatal broilers, which is potentially mediated through the transcriptional upregulation of Pax3, Pax7, MyoD, MyoG and Myf5 and the key factors (Wnt3a and β-catenin) of Wnt/β-catenin signaling pathway.. | |||

| Abstract:The prolonged protective effect of glucagon-like peptide-2 (GLP-2) on lipopolysaccharide (LPS)-induced intestinal injury was studied in weaned piglets, and a possible mechanism is proposed. Thirty 28-day-old weaned castrated piglets with initial BW of 6.8 ± 0.4 kg were randomly allotted to three groups: (i) non-challenged control; (ii) LPS-challenged control; (iii) LPS + high GLP-2. Piglets in groups (ii) and (iii) were s.c. injected with PBS supplemented with human [Gly2]GLP-21-34 at doses of 0 or 10 nmol/kg BW per day ,respectively, for seven consecutive days. Piglets were challenged with i.p. administration of Escherichia coli LPS at a dose of 100 μg/kg on d 14 to induce intestinal damage. Twenty-four hours later, the piglets were euthanized and intestinal tract samples were collected. On d 7 after weaning, GLP-2 treatment prevented weaning stress-induced increases in the plasma levels of LPS (P < 0.05), D(-)-lactate (P < 0.05), and diamine oxidase (DAO) activity (P < 0.05), as well as the increase in serum levels of pro-inflammatory cytokines (P < 0.05). On d 14, LPS challenge dramatically increased the barrier permeability (P < 0.05) and increased pro-inflammatory cytokines expression in the small intestines (P < 0.05) (except tumor necrosis factor?α (TNF-α) expression in the ileum) (P > 0.05) and cytokines levels in serum (P < 0.05). Lipopolysaccharide disrupted the ultrastructure of tight junction proteins, and decreased the expression of zona occluden-1 (ZO-1) (P < 0.05) and occludin (P < 0.05). Glucagon-like peptide 2 pretreatment reduced the serum level (P < 0.05) and mRNA expression of pro-inflammatory cytokines in the small intestines (P < 0.05) and abrogated the destructive effect of LPS on barrier permeability by restoring the expression and localization of tight junction proteins (P < 0.05). Glucagon-like peptide 2 significantly prevented the LPS-induced increase in the expression of myosin light-chain kinase (MLCK) (P < 0.05) and the increase in phosphorylated myosin light chain (pMLC) levels in the duodenum, jejunum, and ileum. These results indicate that GLP-2 pretreatment alleviates intestinal barrier injury and inflammation in LPS-challenged weaned piglets. The protective effect of GLP-2 involves: 1) stimulation of the expression of tight junction proteins and 2) inhibition of the redistribution of tight junction proteins by down-regulating the activation of the MLCK/pMLC pathway. | |||

| Abstract:The aim of study is to investigate the effect of central administration of neurokinin B (NKB) on the timing of puberty onset and the expression levels of kisspeptin and gonadotrophin releasing hormone (GnRH) genes and proteins in the hypothalamus of rats. Prepubertal Sprague-Dawley rats were divided into three groups: NKB, vehicle, and control groups. The rats in the NKB group received intracerebroventricular injection of NKB solution, those in the vehicle group received injections of an equal volume of saline, and those in the control group did not receive any treatment. The rats were sacrificed, and the hypothalamus was obtained, sectioned, and used for fluorescence immunocolocalization of GnRH and kisspeptin immunoreactivity. Total RNA was extracted and quantified, and the DNA was analyzed using RT-PCR. The results of this study demonstrated that NKB treatment of prepubertal rats expedited the timing of vaginal opening (VO) and increased the ovary and uterus weights. Additionally, the hypothalamic expression of Kiss1 and GnRH mRNA and the number of GnRH-immunoreactive (ir) cells number significantly decreased (P < 0.05) in the arcuate nucleus (ARC) but increased in the paraventricularis nucleus (PVN) and median eminence (ME), while the number of kisspeptin-ir cells significantly increased (P < 0.05) in the ARC and periventricular nucleus (PeN) relative to the control. There were no differences (P > 0.05) in the number of kisspeptin-ir cells in the PVN. Overall, the results suggest that NKB plays a major role in modulating the activity of kisspeptin and GnRH during puberty. Nevertheless, both kisspeptin and GnRH serve different functions in the in the different nuclei of the hypothalamus during the onset of puberty. | |||

| Abstract:Numerous neutral lipids were stored in cytoplasm of porcine oocytes in the form of lipid droplets (LDs). These LDs play an important role in vitro maturation and embryo development. Reconstructed embryos with different lipids were performed in present study to establish a model for study of LDs. Three groups of reconstructed embryos were obtained by hand-made cloning (HMC) and delipation: W-L: whole LDs in embryos; H-L: half LDs in embryos; R-L: removed LDs in embryos. After chemical activation (0h), reconstructed embryos were cultured in WOWs system for 6 days. The in vitro developmental competence of the three kinds of reconstructed was assessed. Results showed that: each kind of these three groups of embryos can develop to blastocyst stage. Therefore, the embryos with other content of LDs can be reconstructed in future studies. Then, the H-L group embryos, which as a model to study the roles of LDs and mitochondria in early development of embryos, were composed of three parts: a half normal oocyte (stained by MitoTracker Red CMXRos before bisecting) without nucleus, a half of delipated oocyte without nucleus and a donor cell. Following, 1-cell (12h), 2-cell (24h), 4-cell (36h) and blastocyst (144h) were collected to observe the distribution of LDs and mitochondria. The results showed that LDs and mitochondria were successfully tracked from 1-cell to blastocyst stage. Both LDs and mitochondria were only visible in normal cytoplasm at 1-cell stage. At 2-cell stage, mitochondria were uniformly distributed in the cytoplasm in 28% of the total number. But the LDs still not evenly distributed. However, both LDs and mitochondria were dispersed fully at 4-cell and blastocyst stage. In conclusion, reconstructed embryos with different lipids were appropriate models for lipids study, as well as investigate the interaction among lipids, mitochondria and other organelles. ????? | |||

| Abstract:In this paper the effects of dietary daidzein alone or in combination with lactulose on humoral immunity, liver oxidant status and colon microbiota of barrows (Landrace×Duroc) challenged with Escherichia coli lipopolysaccharide (LPS). A total of 36 barrows (age, 40 d; initial BW, 9.35±0.17 kg) were randomly allotted into 6 pens (6 pigs/pen; 2 pens/treatment). Dietary treatments were: 1) control (C, n=12, fed an isoflavones-free basic diet), 2) control+daidzein (D, n=12, fed an isoflavones-free basic diet with 50mg/kg of daidzein supplementation), and 3) control+daidzein+lactulose group (D+L, n=12, fed an isoflavones-free basic diet with 1% of lactulose and 50mg/kg of daidzein supplementation). After 23 days, 6 of pigs from each treatment were randomly selected and injected with LPS. After 24 h post injection, dietary daidzein was found significantly increased the peripheral blood lymphocyte proliferation response to both and PHA and LPS stimulation, and daidzein combination with lactulose supplementation had higher response. After 48 h post injection, pigs were killed. In the D and D+L groups, plasma IL-6 level was lower than C group, while cortisol concentration was higher. Furthermore, dietary daidzein or combination with lactulose may improve the profiles of colonic microflora, and maintains the bacteria populations, including hydrogen-utilizing bacteria after LPS challenge. Moreover, by adding lactulose can alleviates the liver oxidative stress caused by LPS challenge in barrows treated with daidzein. | |||

| Abstract:Monochromatic green light-emitting diodes (LED) light stimulation influences the growth performance of chicks posthatch. This study was undertaken with the following objectives: (1) to examine whether the green LED light stimulation induces overheating effect by determining weight loss rate of fertile eggs during incubation period; (2) to look for the eye health and organ development at different ages of embryos and newly hatched chicks. Arbor Acres fertile broiler eggs (n=480) were randomly assigned to 3 incubation groups and exposed to continuous white light, green light, or a dark environment (control) from day 1 to day 19 of incubation. The light sourced from LED lamps with the intensity of 30 lx at eggshell level. The results showed that either green or white light stimuli during embryogenesis did not significantly affect the weight loss rate of fertile egg, hatching time, hatchability, chick embryo or body weight, the weight percentage of heart, liver and eyes, as well as obvious systematic abnormalities in eye weight, side-to-side, back-to-front or corneal diameter from 15 d of embryogenesis to 6 d of posthatch (P > 0.05). Compared with the dark condition, green light stimuli during embryogenesis tended to increase feed intake (P = 0.080), improved the BW gain of birds during 0-6 day posthatch (P < 0.05), and increased the percentage of pectoral muscle to the BW on 3- and 6-day-old birds. In addition, embryos or chicks in green light had lower weight percentage of yolk retention on 19 d of embryogenesis and 1 d of posthatch in comparison to those in dark or white group (P < 0.05). These results suggest providing green LED light during incubation has no detrimental effect on eye health and organ development, but does have potential benefits in terms of enhanced the posthatch growth of broilers. This growth-promoting effect of green light stimulation was not caused by overheating. | |||
