  • Thickness Method for Measuring Hair Density of Rex Rabbit

    Guo Haiqi;Li Bingjing;Liu Han;Zhang Zongcai;

    [Objective] The paper was to characterize hair density by changes in hair thickness under certain pressure.[Method] The effects of weight of thickness tester and wafer area at the bottom of presser foot on measurement results were studied,and the optimal measuring weight and wafer diameter was determined.The measurement results of hair thickness under the above condition were compared with the results of manual counting.Meanwhile,the effects of hair length and hair fineness on hair density were analyzed.[Result] The hair density obtained by manual counting had consistent change trend with the hair thickness measured under certain conditions.If the length and fineness of hairs were introduced for modification,the correlation between hair thickness and hair density would be better.There were little changes in hair length and fineness of rex rabbit,and their effects on hair thickness could be ignored under general condition.[Conclusion] It is completely feasible to characterize hair density of rex rabbit by hair thickness under pressure.

    Guo Tong;Ma Jianmin;Wu Yan;Chen Yajun;Guo Xiushan;

    [Objective] The paper was to investigate effects on fermentation bed temperature,growth performance,diarrhea rate and digestive en-zyme activity of weaning piglets by using spent mushroom substrate of Pleurotus eryngii as padding.[Method] A total of 120 weaning piglets(Duroc × Landrace ×Yorkshire) with average initial body weight of(8.0 ±0.5)kg were allocated to five dietary treatments in a randomized complete block design for 42 d,each of which was replicated three times with eight piglets per replicate(half male,half female).The padding for control group was(50% sawdust +50% rice husk);experimental group Ⅰ 100% spent mushroom substrate;experimental group Ⅱ(15% sawdust +15% rice husk +70% spent mushroom substrate);experimental group Ⅲ(25% sawdust +25% rice husk +50% spent mushroom substrate);experimental group Ⅳ(35% sawdust +35% rice husk +30% spent substrate).[Result] There was no significant difference in surface temperature of fermentation bed between experimental groups and control group(P>0.05).Compared with the control group,the temperature under 20 cm of fermentation bed in ex-perimental groups I,Ⅱ and Ⅲ increased significantly(P<0.05).Except for experimental group Ⅳ,other three experimental groups had higher aver-age daily gain(P<0.05) and experimental group Ⅰ had higher average daily feed intake(P<0.05) compared to the control group.The diarrhea rate and mortality of weaning piglets in experimental groups Ⅱ,Ⅲ and Ⅳ were significantly decreased compared with the control group(P<0.05).Compared with the control group,other three experimental groups had higher digestive enzyme activity in duodenal contents except for experimental group Ⅳ(P<0.05).[Conclusion] Spent mushroom substrate of P.eryngii can be used as fermentation bed padding,and the optimal proportion was experimental group Ⅲ.

    [Objective] The paper was to study the change rule and correlation analysis of quality indexes of chilled chicken within 7 d shelf life.[Method] Six pieces of fresh breast muscle were packaged in polyethylene(PE) food storage bags,labeled,and refrigerated at 4 ℃.The p H,water loss rate,tenderness,color value and inosinic acid content of chicken were measured at different time points of preservation(cold storage for 0,1,2,3,6,7 d).[Result] With the prolongation of shelf life,the p H of chilled chicken first increased then tended to be stable;the water loss rate first increased then stabilized;the shear force first decreased then increased.There was little difference in brightness value(L*) of chilled chicken dur-ing different shelf life(P>0.05).The red degree value(a*) decreased with the prolongation of shelf life;the yellow degree value(b*) increased with the extension of shelf life.The inosinic acid content decreased with the prolongation of shelf life.The p H of chilled chicken in different shelf life had significant positive correlation with water loss rate(P<0.05) and extremely significant negative correlation with shear force(P<0.01).[Conclusion]The shelf life of 7 d has impact on meat color and inosinic acid of chilled chicken.Cold fresh preservation of chilled chicken should be less than 6 d;p H has certain correlation with water loss rate and shear force.

  • Analysis of Pig Price Fluctuation in Recent Decade Based on the Changes in Breeding Scale

    Xu Chi;

    In recent decade,the fluctuation of pig price has become more and more acute with obvious periodicity.Currently,the pig breeding mode dominated by individual households leads to acute fluctuation of pig price to some extent.The scale expansion of recent decade intensified the fluc-tuation of pig price in the short term but will stabilize the price in the long term.Therefore,it is necessary to expand breeding scale for maintaining long-term price stability and the optimal scale should be chosen according to the circumstances to ensure the social benefit maximization.

    Yang Ruisheng;Zhang Junyi;Chen Yubo;Wang Yong;Jiang Yiren;Shi Shenglin;Qin Li;

    [Objective] The paper was to improve the efficiency and accuracy of early forecast of Lepidopteran oak-infesting pests.[Method] DNA barcoding technique was established for quick species identification using mitochondrial cytochrome C oxidase subunit Ⅰ(COⅠ) as the standard gene.This barcoding technique was used to amplify and sequence genomic DNA samples from eggs and pupae of 11 species of Lepidopteran pests collected from oak.[Result] The DNA barcoding standard genes of 594-708 bp were determined from eggs and pupae of Lepidopteran insects.There were differences of 0-2 bases in DNA barcode sequences between conspecific eggs and pupae,with the sequence identity of 99.7%-100%.The average content of A,T,G and C of DNA barcode sequences from Lepidopteran insects were 30.7%,38.5%,14.9% and 15.9%,respectively.The obtained DNA barcode sequences had 91.4%-100% identity and 0-8.6% difference degree with GenBank-deposited DNA barcode sequences from organisms of the genetically-closest relationship.Among them,DNA barcode sequences from egg and pupa samples of 10 Lepidopteran insects(No.1-20) had 99%-100% identity and 0-1.0% difference degree with homologous sequences in GenBank database,while the remaining samples(No.21-22) had high difference degree(8.6%) with homologous sequences.[Conclusion] The established DNA barcoding technique is an effeetive tool for species identification of Lepidopteran pests using genomic DNA from eggs and pupae of Lepidopteran insects.

  • Construction and Immunogenicity of Recombinant Lactococcus lactis Expressing S1 Protein of Porcine Epidemic Diarrhea Virus(PEDV)

    Wang Liping;Han Xianjie;Wang Xiaobin;Gai Chunyun;Li Junwei;Shan Hu;

    To evaluate the specific immune responses induced by recombinant Lactococcus lactis(L.lactis) which expresses porcine epidemic diarrhea virus(PEDV) S1 protein through oral administration,the spike gene fragment of PEDV was amplified from PEDV SDLY strain to construct p MG36 e-S1 recombinant plasmid.The recombinant plasmid was then electro-transferred into competent cells of L.lactis MG1363,to prepare the recombinant L.lactis expressing S1 protein of PEDV.The expression of target protein was identified by SDS-PAGE and Western-blot.New Zealand white rabbits were orally administered with the recombinant strain;the antibody titer in intestinal mucosa and serum was detected by neutralizing test;and the specific Ig G in serum was evaluated by indirect ELISA.The results showed that the recombinant L.lactis could effectively induce high level of Ig G in serum and high level of mucosal immune antibody.The recombinant L.lactis is qualified to be a potential oral vaccine because it could successfully stimulate both humoral and mucosal immune responses against PEDV.

    Dialysis therapy is not a radical cure of chronic renal failure in cats,while renal transplantation is the cure method.Renal transplanta-tion requires rigorous examination of donor and receptor,and the procedure is strictly sterile.The main points of renal transplantation are:renal artery and vein sutured to abdominal aorta and posterior vena cava,respectively;ureter sutured to bladder;minimizing the time of thermal ischemia.Cats should be given immunosuppressant before the operation,and the drug should be administered throughout the life.Various indicators should be monitored regularly to prevent the occurrence of immunological rejection.
