本试验通过添加一定比例的生物分解玉米秸秆,研究猪的采食量及对生长性能的影响。试验选用生长发育健康、体重相近的杜×大×长三元杂交去势瘦肉型商品猪40头,平均体重60.23±0.26㎏,随机分成4组,1个对照组和3个试验组Ⅰ、Ⅱ、Ⅲ),每组10头,进行为期60d的饲喂试验。对照组和试验Ⅰ、Ⅱ、Ⅲ组分别添加0、20%、25%、30%的生物秸秆分解剂发酵的玉米秸秆饲料代替日粮中的部分营养成分。从育肥性能进行分析,试验Ⅰ、Ⅱ、Ⅲ组的头均日增重较对照组分别降低了2.44%、0.32%、5.16%,试验Ⅱ组与对照组头均日增重差异不显著(P〉0.05),Ⅰ组较对照组差异显著(P〈0.05),Ⅲ组较对照组差异极限著(P〈0.01);试验Ⅰ、Ⅱ、Ⅲ组较对照组头均纯收入分别增加14.74元、20.03元、3.83元,分别提高了4.58%、6.22%、1.19%。由此看出,日粮中添加20%、25%、30%的处理玉米秸秆饲料饲喂瘦肉型猪经济效益好,其中添加比例为25%的试验Ⅱ组最为理想。
本試驗通過添加一定比例的生物分解玉米秸稈,研究豬的採食量及對生長性能的影響。試驗選用生長髮育健康、體重相近的杜×大×長三元雜交去勢瘦肉型商品豬40頭,平均體重60.23±0.26㎏,隨機分成4組,1箇對照組和3箇試驗組Ⅰ、Ⅱ、Ⅲ),每組10頭,進行為期60d的飼餵試驗。對照組和試驗Ⅰ、Ⅱ、Ⅲ組分彆添加0、20%、25%、30%的生物秸稈分解劑髮酵的玉米秸稈飼料代替日糧中的部分營養成分。從育肥性能進行分析,試驗Ⅰ、Ⅱ、Ⅲ組的頭均日增重較對照組分彆降低瞭2.44%、0.32%、5.16%,試驗Ⅱ組與對照組頭均日增重差異不顯著(P〉0.05),Ⅰ組較對照組差異顯著(P〈0.05),Ⅲ組較對照組差異極限著(P〈0.01);試驗Ⅰ、Ⅱ、Ⅲ組較對照組頭均純收入分彆增加14.74元、20.03元、3.83元,分彆提高瞭4.58%、6.22%、1.19%。由此看齣,日糧中添加20%、25%、30%的處理玉米秸稈飼料飼餵瘦肉型豬經濟效益好,其中添加比例為25%的試驗Ⅱ組最為理想。

Abstract:This study aimed to evaluate the effects of corn stalk treated with biological decomposition agent on swine growth performance. 40 healthy and similar castrated lean pigs with similar weights (average weight 60.23+0.26 k9) were randomly divided into 4 groups, 1 control and 3 experimental groups,10 pigs in each group, for a period of 60 days experiment. 0, 20 %, 25 %and 30%fementation corn stalk were supplemented to 4 groups, respectively. Analysis of fattening performance showed that average daily weight gain of experimental groups decreased 2.44 % ,0.32%and 5.16 %, respectively, compared with con- trol group. Group 2 showed non--significant difference with control one(P〉0.05), group 1 showed significant difference with control one(P〈0.05), group 3 showed remarkable difference with control one(P〈0.01)..Each pig net profit of experimental groups increased ¥14.74(4.58%),¥20.03(6.22%) and 3/73.83(1.19 %), respectively, compared to control group. To sum up, dietary supplemented with 20 %, 25 % and 30% corn treated with biological decomposition agent obtained better efficiency, especially, 25%group showed the best effect.
