Comparative Study on Growth Performance of Luxi Cattle Fed with Ammoniated and Microbial Straw

A growth and fattening trial for Luxi cattle fed with treated wheat straw and corn stalk were conducted to evaluate the growth performance. 30 cattle were randomly divided into 6 groups with 5 animals each, the average daily gains (ADG) of animals fed ammoniated corn stalk and wheat straw 0.931 kg and 1.012 kg; the ADG of animals fed with microbial wheat straw and corn stalk were 0.985 kg and 1.064 kg; the ADG of two control group fed wheat straw and corn stalk were 0.684 kg and 0.708 kg. The ADG of animals fed with treated wheat straw or corn stalk was signifi- cantly greater (P0.01) than that of animals in control group, while the ADG of ammoniated and microbial straw or stalk were similar (P0.05). The economic analysis for the 60 d trial indicated the daily profit of groups fed ammoniat- ed, microbial and untreated wheat straw was 2.103 Yuan, 2.665 Yuan and 0.806 Yuan; the daily profit of groups fed ammoniated, microbial and untreated wheat straw was 2.279 Yuan, 2.960 Yuan and 0.819 Yuan. In conclusion, the profit of feeding Luxi Cattle with the microbial corn stalk was better than that with ammoniated and microbial wheat straw, and was much better than that with the untreated straw, the ammonia or microbial treatment of wheat straw and corn stalk was worth great extension in rural area.
