新型猪饲料风味剂──猪宝香的效果研究

A STUDY OF PIG FLAVOR EFFICACY

进行二个试验，研究新型猪饲料风味剂──猪宝香的效果和适宜用量。结果表明，猪宝香Ⅰ型能明显提高仔猪采食量，日增重和饲料利用率，其效果均优于乳猪香，添加Ⅰ型后的经济效益明显高于乳猪香。Ⅱ型和Ⅲ型促进采食的效果高于乳猪香，其他指标均低于乳猪香。添加风味剂对血浆尿素氮无影响。综合考察各项指标表明，猪宝香Ⅰ型的适宜用量为２５０—５００ｐｐｍ。仔猪日龄越小，添加风味剂的效果越好。

Two experiments were conducted to study the efficacy and optimum using level of ZHUBAOZIANG(ABX),a newly-produced pig flavor.Exp.1 compared three types of ZBX to Pig Kcrave(PK),a pig flavor produced in U.S.A.Basal diet was added with 500ppm of Pk,ZBX1,ZBX2,ZBX3 or without flavors.In Exp.2,0,250,500 or 1000ppm ZBX1 was added to basal diet to determine the optimum amount used in pig feed.Pigs of 38 days old were used for 21-day trial after a 9-day pre-trial.Results showed that ZBX1 could increase feed intake、daily gain、feed conversion efficiency and economic benefits of pigs to a larger exent than PK.ZBX2 and ZBX3 were superior in increasing feed intake but inperior in other aspects to PK,Serum urea nitrogen content was not influenced by addition of flavors in diets.Results ot Exp.2 indicated that the optimum using ievel of ZBX1 is 250-500ppm.The younger the pigs,the higher the efficacy addition of ABX in diets.
