This study was conducted to detect quantitative trait loci (QTL) affecting growth and body composition in an F2 reference population of Korean native pig and Landrace crossbreds. The three-generation ...
To elucidate the efficacy of different levels of microbial-fermented soy proteins (FSP) on piglet performance, a total of 240 weaned piglets (L??Y??D, 22?? d of age, 5.16??.07 kg initial BW) were allo...
Reactive oxygen species (ROS) generate during electrical activation of oocytes which has detrimental effects on embryo survival when overwhelmed. The present study was designed to investigate the abil...
Seventeen haplotypes were detected from the complete mitochondrial DNA control region sequences analyzed from eighty individuals of two Tibetan domestic sheep breeds. The nucleotide composition of all...
This study was carried out to determine the effect of vitamin E and vitamin C on the performance of Japanese quails (Coturnix coturnix japonica) reared under heat stress during the growth and egg prod...
The objectives of this study were to characterize the changes occurring in the levels of insulin-like growth factors (IGF-I and IGF-II) in bovine milk during a one-year lactation period, and to determ...
A growth trial (Expt. 1) and an in vitro fermentation experiment (Expt. 2) were conducted to determine the response of growth performance, cecal fermentation characteristics and in vitro gas productio...
The seasonality of reproduction and embryonic development of spiny dogfish (Squalus acanthias) sampled from the Eastern Black Sea were studied. The gestation period of spiny dogfish, starting in Augus...
小鼠睾丸发育过程中Si1基因表达的研究     小鼠  睾丸  Si1基因  基因表达  凋亡       font style='font-size:12px;'> 2012/11/12
以1天龄、未成熟(3周龄)、成熟期(10周龄以上)的昆明正常小鼠睾丸组织为实验材料,利用地高辛标记的Si1基因探针在其组织切片上进行DNA-mRNA分子原位杂交,探讨Si1基因在小鼠睾丸发育过程中的表达变化.同时,分别在生后15,20 d及25 d的昆明小鼠睾丸组织切片上进行凋亡细胞原位检测,验证小鼠睾丸上述发育时期的细胞凋亡情况.结果发现:①Si1基因在1天龄小鼠的睾丸组织生精上皮内无杂交信号;...
Leptin receptor (OBR) is a member of the class I cytokine receptor family. It signals mainly via the JAK/STAT pathway and plays an important role in regulating body energy storage and metabolism. This...
The polymorphism of insulin-like growth factor I receptor (IGFIR) gene in 12 pig breeds (total n = 593) was detected by PCR-SacII-restriction fragment length polymorphism and allele A (379 bp) or alle...
This experiment was carried out to determine the effects of supplementation of L-carnitine and humic substances alone or in combination in laying hen diets on performance, egg traits and blood paramet...
One hundred and sixty crossbred pigs (6.62??.36 kg) weaned at day 18?? were used to investigate the effects of lactitol and tributyrin on performance, small intestinal morphology and enzyme activity. ...
Enterotoxigenic Escherichia coli is a major cause of diarrhea in neonatal and post-weaning piglets. To determine the most common fimbrial antigens of ETEC in piglets with diarrhea, two investigations ...
An experiment was conducted to investigate the effects of supplemental copper (Cu) chelates (methionine, chitosan and yeast) on the performance, nutrient digestibility, serum IgG level, gizzard erosio...
