Abstract
The impact of three different brands of microbial phytase added with two different DCP levels (0. 44% and 0. 77%) on broiler performance and calcium and phosphorus digestibility was studied. The results showed that: compared with the control group of normal DCP level, feed intake and daily gain of broilers with lower DCP and adding phytase was close to the control group, but the feed conversion ratio had some improvement, mortality and lame rate had no significant difference with that of the control group. Reduction of the DCP and addition of phytase could improve broilers' ash apparent digestibility (P >0. 05), significantly improve the digestibility of apparent phosphorus (P<0. 05), and substantially increase apparent digestibility in the 24 days broilers' calcium (P<0. 01) , and there was a modest increase in the 42 days broilers calcium apparent digestibility (P>0. 05). The effect of different phytases had some differences.关键词
