| Precipitation, throughfall and stemflow were monitored and collected through the rainy season on a natural forest ecosystem of Pinus densata in the Gongbu Nature Reserve in Tibet. The concentrations of N, P, K, Na, Ca, Mg, Si, Mn, Fe, S, Zn and Cu were analyzed in the precipitation, throughfall and stemflow waters, Thereafter, and according to the amount of water of precipitation, throughfall and stemflow, the net input was calculated for each nutrient in the forest. The results showed that: (1) During the entire rainy season, the average concentration of different nutrients in the precipitation of the Pinus densata forest was ranked in the following order: N>K>Na>Ca>Mg>Si>P>Mn>Fe>S>Zn>Cu. The concentration of N 29.6145... |

| 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... |
