不同复合酶制剂对肥育猪生长性能的影响

试验选用72头100日龄,体重在44kg左右的三元杂交(杜×长×大)商品代瘦肉型肥育猪,完全随机分为3个组(A、B、C),每个组24头,设三个重复。A组中,饲料中加入国产复合A酶;B组中,饲料中加入国产复合B酶;C组中,饲料中加入罗酶宝TM。经过30天的饲养试验,结果表明:①B、C两组肥育猪的日增重比A组分别提高0.81%、5.50%,C组比B组日增重提高4.65%;②C组肥育猪料重比比A组提高3.53%,C组料重比比B组提高2.59%,B组料重比比A组提高0.96%;③经济效益,C组比A、B两组分别提高8.59%、5.99%;④试验全期,三个处理组的腹泻率均极低。

Effect of Different feed enzymes on growthperformance of finishing pigs

three -way cross -bredDuroc X(Landrace X Yorshine)]lean meat finishing pigs were used to evalute the effects of different Enzymes.Initial average weight of finishing pigs is 44kg(P>0.01),Initial age is 100days.The finishi ng pigs were randomly allocated to 3die tary treatments with 3replication(8finishing pigs for each replicatio n).The 3treatments feed enzyme A?enzyme B and ROVABIO TM .At day30,The result showed that the treatm ents feeding enzyme enzyme B and ROVABIO TM average daily gain increased by0.81%and 5.50%(P <0.05)and feed to gain ratio in-creased by 3.53%and 2.59%(P>0.05).Result also demonstrated that feed ROVABIO TM reduced costs of pro-duction and had a lower incidence of diarrehea.
