[Method] Sixty weaned piglets, 25 days old, were randomly divided into two groups, six replicates each group, and each replicate contained five piglets. Piglets in control group were fed with the conversation feed developed by traditional granulating process, and those in experimental group were fed with the conservation feed developed by post-expanding lower temperature granulating process. The trial lasted 28 d. [Result] Compared to traditional granulating process, post-expanding lower temperature granulating process significantly enhanced starch gelatinization degree of conservation feed by56.9%(P〈0.05), and significantly improved in vitro protein digestibility of conservation feed by 11.48%(P〈0.05). Compared to the control group, the feed intake of piglets in experimental group was increased by 21.63%(P〈0.05); the average daily gain was increased by 27.61%(P〈0.05); the diarrhea rate was lowered; and the feed gain ratio was improved by 4.51%(P〉0.05). The results suggested that post-expanding lower temperature granulating process effectively enhanced feed digestion and absorption of piglets. [Conclusion] The paper provides a theoretical basis and practical reference for improvement of production process of conservation feed.展开更多

The former consisted of settling time (ST), aeration time (AT), superficial gas velocity (SGV), height/diameter (H/D) ratio and organic loading rates (OLR), the latter included sludge volume index (SVI) and set-up time. The calculated result showed that for SVI and set-up time, the influence orders and the corresponding grey entropy relational grades (GERG) were: SGV (0.9935) 〉 AT (0.9921) 〉 OLR (0.9894) 〉 ST (0.9876) 〉 H/D (0.9857) and SGV (0.9928) 〉 H/D (0.9914) 〉 AT (0.9909) 〉 OLR (0.9897) 〉 ST (0.9878). The chosen parameters were all key impact factors as each GERG was larger than 0.98. SGV played an important role in improving SVI transformation and facilitating the set-up process. The influence of ST on SVI and set-up time was relatively low due to its dual functions. SVI transformation and rapid set-up demanded different optimal I-I/D ratio scopes (10-20 and 16-20). Meanwhile, different functions could be obtained through adjusting certain factors' scope.展开更多
