| Understanding the changes in the total bud bank, and its contribution to community regeneration, in response to grassland enclosure to livestock grazing, is crucial for grassland management. Despite its importance, the contribution of the total bud bank and that of different bud types to community regeneration as a whole have been rarely explored. The vegetative offspring recruited from different bud types was investigated in grasslands having different enclosure durations to livestock grazing on a typical steppe of Inner Mongolia, China. Total vegetative offspring density was significantly higher (p<0.05) under continuous grazing than in fenced grasslands, but no significant changes were found among plots with different enclosure durations to livestock... |

| Abstract This experiment was conducted to study the effects of arginine supplementation on organ development, egg quality, blood parameters, and immune status of laying hens. A total of 360 25-week-old brown Leghorn laying hens were randomly divided into three groups with six replicates of 20 birds each and fed diets supplemented with 0, 8.5, or 17 mg of L-arginine/kg for 42 days. Results showed that the weight of proventriculus and duodenum in the treatment supplemented with 17 mg/kg L-arginine was heavier than that of 0 mg L-arginine/kg treatment (p<0.05). The weight of oviduct in the treatments supplemented with 17 mg/kg L-arginine was smaller than that of 0 and 8.5 mg L-arginine/kg treatment (p<0.05), and the small yellow follicle amount in the... |

| ABSTRACTHMOX1 is an important gene in biosynthesis of the eggshell pigment of blue eggs. Previous studies found that HMOX1 is highly expressed in the shell gland of hens laying blue eggs (BlueH) compared with hens laying brown eggs (BrownH); however, the reasons for the differential expression are unclear. In this study five single nucleotide polymorphism (SNP) in HMOX1 were genotyped in 111 BlueH and 115 BrownH. The association of haplotypes of these SNP with the blue egg phenotype was tested. Haplotype-specific expression of HMOX1 was detected in the shell gland. The interaction of sequence variants and transcription factors was analyzed using electrophoretic mobility shift assay (EMSA). A TG haplotype covering upstream 1.4 kb region of HMOX1 was... |
