Effect of Pineapple Leaf Pomace Silage on Growth Performance of Finishing Pigs

研究菠萝叶渣青贮饲料对生长育肥猪生长性能的影响,结果表明:试验组B、C、D平均日增重分别比对照组A提高826.31、805.25和796.46 g;料肉比分别比对照组A降低9.84%、6.33%和2.27%;每头猪效益分别比对照组A提高70.94、18.62、7.74元/头;猪肉品质也比对照组A有不同程度的提高,尤其以添加4%菠萝叶渣饲料肥育猪的日增重、料肉比和经济效益均最好。

4 treatments and 30 repetitions were designed in the experiment and the influence of fermentative pineapple leaf residue silage on the growth performance of growing-finishing pigs was studied. The additive amount of fermentative pineapple leaf residues in tested daily ration was respectively 0 %, 4 %, 8 % and 12 %, i.e. test group A（control group）： only basic daily ration was fed to finishing pigs; test group B：basic daily ration ＋ 4 % fermentative pineapple leaf residues; test group C： basic daily ration ＋ 8 % fermentative pineapple leaf residues; test group D： basic daily ration ＋ 12 % fermentative pineapple leaf residues.The result shows the following： the average daily gain in control group A and test groups B, C and D respectively increased by 786.25, 826.31, 805.25 g and 796.46 g; compared to control group A,feed conversion ratio in test groups B, C and D respectively reduced by 9.84 %, 6.33 % and 2.27 %, the benefit of each pig respectively increased by 70.94, 18.62 and 7.74 Yuan and pork quality improved to different extents. In particular, daily gain, feed conversion ratio and economic benefit of finishing pigs were the maximum after the addition of 4% pineapple leaf residue silage.
