Caloric Values in Leaves of Some Bamboo Species in the Bamboo Garden of Hua'an County, Fujian

在冬季对福建省华安县竹园 1 4属 46种 (含变种和栽培型 )竹类植物叶的热值和灰分含量进行了研究。结果表明 :竹类植物叶的灰分含量在 8.0 5%～ 2 8.1 4%之间 ,平均为 1 5.1 8% ;干重热值在 1 4957.3～ 1 91 1 1 .4J/g之间 ,平均为 1 7672 .1J/g ;去灰分热值在 1 9473.1～ 2 4 646.2J/g之间 ,平均为 2 0 845.6J/g ;竹类植物叶干重热值和灰分含量有显著的线性关系 ,相关方程为Y =- 1 69.2 1X + 2 0 2 4 1 (r=0 .7370 ,df=44) ,高灰分含量是竹叶干重热值相对较低的重要原因之一。The ash contents, gross caloric values and ash free caloric values in leaves of 46 bamboo taxa (including varieties and cultivars) of 14 genus in the Bamboo Garden of Hua'an County, Fujian in winter were studied. The ash contents, gross caloric values and ash free caloric values in leaves of these bamboo taxa varied from 8.05% to 28.14%, from 14957.3J/g to 19111.4J/g and from 19473.1J/g to 24646.2J/g, respectively. Gross caloric values (Y) correlated remarkably with ash contents(X), the regression equation being Y= -169.21X+20241( r =0.7370 ** , df=44). The high ash contents resulted in low caloric values in dry leaves of bamboos

Effects of Fermented Soybean Meal Supplementation on Ammonia Emissions from Piglet Manure

研究了枯草芽孢杆菌、酿酒酵母和乳杆菌混合发酵豆粕对仔猪粪便氨气排放的影响。以基础日粮作为对照,分别添加7.33%湿发酵豆粕和5%干发酵豆粕,对75头41日龄的仔猪进行28d的饲养,然后利用箱式堆肥装置对仔猪粪便进行7d的静置产氨试验。结果表明,湿发酵豆粕组仔猪粪便1d和7d产氨量都显著低于干发酵豆粕组（P〈0.05）,干发酵豆粕组仔猪粪便1天和7天产氨量都显著低于对照组（P〈0.05）,湿、干发酵豆粕组仔猪粪便1d产氨量较对照组分别降低了33.46%、13.39%,7d产氨量较对照组分别降低了23.53%、13.26%。由此可见,添加7.33%湿发酵豆粕或5%干发酵豆粕均可以减少粪便氨气排放,前者效果更好。This study aims to evaluate the effects of fermented soybean meal by Bacillus subtilis, Saccharomyces cerevisiae and Bacillus lactis on manure ammonia emission of piglets. A total of 75 piglets with an initial body weight of 13.14 ＋ 0.22 kg were used in four weeks feeding trial, which was conducted using diets containing 7.33 % wet-fermented soybean meal or 5 % dry-fermented soybean meal, respective- ly. The manure of piglets was collected to a composting chamber to determine the ammonia production for 7 days. The results showed that the ammonia production of manure in wet-fermented soybean meal group was significantly lower than that in dry-fermented soybean meal group （P〈0.05）, and the ammonia pro- duction of manure in dry-fermented soybean meal group was significantly lower than that in control group （P〈0.05）. Compared with control group, the ammonia production of manure for both wet-fermented soy- bean meal group and dry-fermented soybean meal group decreased by 33.46% and 13.39% respectively on the first day, and by 23.53% and 13.26% in 7 days. In conclusion, the addition of 7.33% wet-fermented soybean meal or 5% dry-fermented soybean meal could reduce ammonia emission of manure, and wet-fer- mented soybean meal had a higher emission reduction compared with dry-fermented soybean meal
