Background:Whey permeate is an effective lactose source for nursery pigs and the most benefits are obtained when pigs are at 7 to 11 kg *** weaning ages could cause different length of early-weaner phases until 7 kg BW and thus it would influence the dietary need of whey permeate during 7 to 11 kg BW of *** study aimed to evaluate if weaning ages would affect the dietary needs of whey permeate for optimum growth performance of pigs at 7 to 11 kg ***:A total of 1,632 pigs were weaned at d 21(d 21.2±1.3)or d 25(d 24.6±1.1)after *** pigs had a common early-weaner feeds until they reached 7 kg *** pigs reached 7 kg BW within a weaning age group,they were allotted in a randomized complete block design(2×4 factorial).Two factors were weaning age groups(21 and 25 d of age)and varying whey permeate levels(7.50%,11.25%,15.00%,and 18.75%).Data were analyzed using the GLM and NLIN procedures of SAS for slope-ratio and broken-line analyses to determine the growth response to whey permeate and optimal daily whey permeate intake for the growth of the pigs weaned at different ***:Pigs weaned at 21 d of age had a common diet for 11 d to reach 7 kg BW whereas pigs weaned at 25 d of age needed 2 *** G:F of pigs weaned at 25 d of age responded to increased daily whey permeate intake greater(P<0.05)than pigs weaned at 21 d of *** were obtained(P<0.05)at 88 and 60 g/d daily whey permeate intake or 17.0%and 14.4%of whey permeate for G:F of pigs weaned at 21 and 25 d of age,***:Pigs weaned at an older age with a short early-weaner phase had a greater growth response to whey permeate intake compared with pigs weaned at a younger age with a long early-weaner *** weaning ages affected dietary needs of whey permeate for optimum growth performance of pigs from 7 to 11 kg BW.

New Distribution Records for Sphenomorphus tonkinensis(Lacertilia: Scincidae) with Notes on Its Variation and Diagnostic Characters

引用

Asian Herpetological Research 2013年第2期4卷 147-150页

作者： Yingyong WANG Jianhuan YANG Yang LIU State Key Laboratory of Biocontrol and School of Life Sciences Sun Yat-sen University Kadoorie Conservation China Kadoorie Farm and Botanic Garden

Sphenomorphus tonkinensis is a recently described new species based on specimens collected from northern Vietnam and Hainan, China. Herein, we report 13 additional specimens of S. tonkinensis from five new localities in Guangxi, Guangdong and Jiangxi, southern China. These specimens were compared with the type specimens of S. tonki- nens＆, which allows us to revise the diagnostic characteristics of this newly described species. Additional information on morphological variation, distribution and reproductive biology are provided, which extends our understanding of the natural history of S. tonkinensis.

ANALYSIS OF THE TELECONNECTIONAL STRUCTURES OF THE 500-hPa HEIGHT FIELD OVER THE NH IN JANUARY

Advances in Atmospheric Sciences 1987年第2期4卷 185-197页

作者：王盘兴高智李长清 farm Administration of Helongjiang Province Harbin Nanjing Nanjing Institute of Meteorology Weather Center of Shaanxi Province Xi’an

Based on the oblique mode scheme provided in the Appendix, and analysis is made of the tcleconnectional structures (TNS) of the NH 500-hPa height field in January, resulting in a series of teleconnectional patterns representative of the main features of TNS, of which the teleconnectional pattern WPAA (Western Pacific/Asian/ American) closely related to the East-Asian circulation is presented for the first time in this field of research. Contrast analysis indicates that TNS are so sensitive to the transition of seasons that a slight transition would bring about a considerable response. Hence the examination of the month-to-month TNS of the NH atmospheric circulations is indispensable.

Journal of Integrative Agriculture 2015年第6期14卷 1163-1170页

作者： Hyun Suk Lee Gihwan Yi Kyung Min Kim Division of Plant Biosciences School of Applied Biosciences College of Agriculture and Life Science Kyungpook National University Department of farm Management College of Agriculture and Life Science Kyungpook National University

This study was carried out to evaluate the expression of yellow endosperm color in the progeny of Psy-2A-Crt I（β-carotene gene, PAC） transgenic plants crossed with IR36. The selected 25 lines of F2 progeny exhibited stable expression of yellow endosperm color and high agronomic characteristics. IR36 and PAC transgenic plant of the grain length, width and ratio showed the same tendency of normal distribution. For progeny selection, colorimeters were as employed to distinguish differing visible colors. Correlation analysis was conducted to investigate the relationship between b＊ value and the expression of specific genes. b＊ value was associated with the relative expression of the PAC-Rev and MAR product by real-time PCR and t-test revealed significant difference. Based on this study, correlation between colorimetric values and real-time PCR was effective to detect gene expression. Yellow endosperm progenies represent a new genetic pool that might be useful to increase the genetic diversity of yellow endosperm rice.

＜正＞Ruminants transform feed components preferentially in body mass or milk. Dairy breeds such as Holstein-Friesian are especially apt in secreting metabolised feed in milk. Generally, such breeds are categorized as the transformation, secretion or dairy type. In contrast, beef cattle such as the Charolais breed are characterized by their ability to accrete synthesized substance as meat, therefore they are categorized as accretion or meat type. The objective of this study was to investigate the growth-and breed-related changes of muscle fiber, adipocyte and hormones.

Genetic Variation of EPAS1 Gene in Tibetan Pigs and Three Low-Altitude Pig Breeds in China

引用

Journal of Integrative Agriculture 2014年第9期13卷 1990-1998页

作者： DONG Kun-zhe KANG Ye YAO Na SHU Guo-tao ZUO Qing-qing ZHAO Qian-jun MA Yue-hui Key Laboratory of farm Animal Genetic Resources and Utilization Ministry of Agriculture/Institute of Animal Science Chinese Academy of Agricultural Sciences College of Animal Science and Technology Yunnan Agricultural University

Endothelial PAS domain protein 1（EPAS1）, also called hypoxia-inducible factor-2, is a key regulatory factor of hypoxic responses and plays an essential role in high-altitude adaptation in mammalian species. In this study, polymorphisms of EPAS1 were detected in 217 individuals from 2 Tibetan pig populations and 3 low-altitude pig breeds by DNA pooling, PCR-SSCP, PCR-RFLP and DNA sequencing methods. A total of 14 synonymous polymorphisms were identified in the coding region. The analysis suggested that SNP1（G963A）, SNP7（C1632T）, SNP10（G1929A） and SNP11（G1947A） showed potential association with high-altitude environment because of their particular variation patterns in Tibetan pigs. Linkage disequilibrium（LD） of these SNPs was analyzed. One common LD block including 5 SNPs clustering in exon 12 was identified in all studied pig populations. Haplotype H1（AGGTC） in LD block was dominant in Tibetan pigs（76.6 and 74.2% in Linzhi（LZ） and Chayu（CY） pigs, respectively） and segregated at higher frequency than that in low-altitude pig breeds（52.3, 58.7 and 56.2% in Wuzhishan（WZS）, Min（M） and Laiwu（LW） pigs, respectively）, indicating that H1 may relate to adaptation to high altitude in Tibetan pigs. These findings raise hope that EPAS1 gene can be a candidate gene that involved in adaptation of high altitude in Tibetan pigs.
