Fermentation Condition of Pleurotus eryngii Waste Sticks Feed and Its Feed Effects on Goats
摘要
Abstract
To explore the suitable fermentation conditions for Pleurotus eryngii waste sticks(PEWS)mixed with soybean meal and bran,as well as the effects of fermented PEWS feed on performance of Matou goats. In test 1, PEWS were used as the main raw materials, and different ratios of bran and soybean meal(4% and 4%,4% and 2%,2% and 4%, as well as 2% and 2%)were supplemented. The fermentation agent was ef-fective microorganisms(EM)original liquid. The moisture was adjusted to about 30%. After 12 days of anae-robic fermentation at room temperature, fermentation quality, nutritional components and aflatoxin B1(AFB1) contents were evaluated. The best combination was selected for feeding test. In test 2, sixty Matou goats (wethers)were randomly divided into 5 groups including 3 experimental groups and 2 control groups. Fermen-ted PEWS feed supplemental ratio in experimental groups were 30%,45% and 60%, respectively, and unfer-mented PEWS supplemental ratio in control groups were30% and 60%,respectively. Each group had three rep-licates with 4 goats per replicate. The test lasted for 45 d including 5 d of pre-test period and 40 d of test period. The results showed as follows:1)When the supplemental ratios of soybean meal and bran were 4% and 2%, respectively, fermentation quality of fermented PEWS feed was the best, and the content of AFB1 was lower. Compared with unfermented PEWS, crude fiber, neutral detergent fiber and acid detergent fiber contents of fermented PEWS feed were decreased by 8.78%,11.56% and 18.88%,respectively,crude protein and crude ash contents were increased by 19.32% and 8.29%,respectively,and AFB1content as low as 3.03 μg/kg. 2) There were no significant differences in performance of goats in different groups(P>0.05). With the increase of fermented PEWS feed supplemental ratio,body weight gain(BWG)and average daily gain(ADG)tended to be decreased,and feed to gain ratio(F/G)and feed cost tended to be increased. Compared with the supple-mentation of 30% unfermented PEWS, the supplementation of 30% fermented PEWS feed had higher BWG, ADG and dry matter intake, and lower F/G. In conclusion, using EM original liquid to ferment PEWS, the supplementation of 4% soybean meal and 2% bran can help improve fermentation quality;the supplemental ra-tio of 30% of fermented PEWS feed in diet for Matou goat is the best.关键词
