Comparative Study on Nutrients Compositions of Different Types of Distillers' Grains
摘要
Abstract
This experiment was conducted to compare the nutrients compositions and evaluate the nutrients val-ues of different types of distillers' grains. The 24 distillers' grains samples were divided into five categories, 8 Luzhou-sorghum distillers' grains ( L-SDG) , 4 Maotai-sorghum distillers' grains ( M-SDG) , 4 highland bar-ley distillers' grains ( HBDG) , 3 corn distillers' grains ( CDG) , 5 barley brewers' grains ( BBG) , analysed the nutrients compositions, evaluated ruminal fermentation characteristics by Cornell net carbohydrate and pro-tein system ( CNCPS) , determined the contents of iron, copper, manganese and zinc by atomic absorption spectrometry, and determined the contents of anti-nutritional factors, such as tannin and silicon. The results showed as follows: 1 ) the pH and primary moisture content of BBG were significantly higher than those of other distillers' grains ( P<0.05) . 2) BBG had the highest content of crude protein, and significantly higher than that of L-SDG, HBDG and CDG ( P<0.05) . The neutral detergent insoluble protein ( NDIP) content of BBG and M-SDG was significantly higher than that of other distillers' grains ( P<0.05) . The acid detergent in-soluble protein ( ADIP) content of L-SDG and M-SDG was significantly higher than that of other distillers' grains ( P<0.05) . The ether extract content of CDG was significantly higher than that of other distillers' grains ( P<0.05) . The crude fiber, neutral detergent fiber, acid washing fiber and acid detergent lignin contents of M-SDG were significantly higher than those of other distillers' grains ( P<0.05) . The starch content of CDG was significantly higher than that of other distillers' grains ( P<0.05) , the starch content of BBG was signifi-cantly lower than that of other distillers' grains ( P<0.05) . 3) According to the CNCPS method' division, the of carbohydrate proportion of BBG ( CA ) was significantly higher than that of other distillers ' grains ( P<0.05), the carbohydrate proportion of CDG (CB1) was significantly higher than that of other distillers' grains ( P<0.05) , the carbohydrate proportion of L-SDG ( CC) was significantly higher than that of other distillers' grains (P<0.05), the protein proportion of BBG (PB3) was significantly higher than that of other distillers' grains ( P<0.05) , the protein proportion of L-SDG ( PC) was significantly higher than that of other distillers' grains ( P<0.05) . 4) The iron and manganese contents of L-SDG and M-SDG were significantly higher than those of other distillers' grains ( P<0.05) , the copper and zinc contents of BBG were significantly higher than those of other distillers' grains ( P<0.05) . 5) The tannin content of BBG was significantly lower than that of other distillers' grains ( P<0.05) , the silicon content of L-SDG was significantly higher than that of other dis-tillers' grains (P<0.05). It is concluded that there are differences in the conventional nutrients of different types of distillers' grains. CDG provide the highest carbohydrate quality and BBG provide the highest protein quality, HBDG and M-SDG have better quality, and the quality of L-SDG is the worst. We should add them in feed reasonably based on the actual production needs.关键词
