摘要
试验探讨肉仔鸡日粮中添加不同形态的微量元素对其生产性能、屠宰性能、血清酶活性的影响.试验分为全无机、全有机、有机和无机各半3个试验组.试验结果表明,在肉仔鸡生长前期（1～21日龄）,全有机组生产性能优于全无机组（P＞0.05）,从后期和全期来看,全有机组生产性能优于无机组（P＞0.05）;有机组腹脂率和腹脂厚度分别比无机组降低7.55％和11.64％ （P＞0.05）.与无机组相比,有机组腿肌率显著提高22.07％ （P＜0.05）;有机组有提高胫骨长度和宽度的趋势（P＞0.05）,有机组有提高血清碱性磷酸酶和5＇-核苷酸酶活性,并有降低血清尿素氮的趋势（P＞0.05）.由此可见,有机微量元素可以提高肉鸡的生产性能,对肉鸡屠宰性能、血清酶活和尿素氮方面有一定影响.
The experiment studied the comparison of different composition of trace element forms on productiv- ity, slaughter performance, serum enzyme activity in broilers. The experiment was designed with three treatments, in- cluding inorganic trace mineral group（ITM）, chelated trace mineral group（CTM） and one-half of inorganic and che- lated trace mineral group（ITM＋CTM） individually. The results showed that the growth performance of broilers with CTM was better than ITM slightly（P〉0.05）. The broilers in CTM group was decreased by 7.55% and 11.64% than ITM group on the abdominal fat and subcutaneous fat respectively （P〉0.05）, and could increase 22.07% of leg mus- cle significantly（P〈0.05）. The length and width of the tibia tended to increase in the broilers fed CTM（P〉0.05）. Com- pared with ITM treatment, the CTM group can increase serum alkaline phosphatase and 5＇-nucleotidase activity, and also had a tendency of decreasing the content of serum urea nitrogen（P〉0.05）. Consequently, using the composition of CTM can improve the production performance, effect slaughter performance, blood urea nitrogen and serum en- zyme activity in broilers.
