Body Weight Gain Effect by using Whole Corn Silage Feeding Beef Cattle

【Objective】To discuss the feeding effect on beef cattle by whole corn silage.【Method】20 Simmental hybrid cattle in 18-month old with similar body weight were selected and randomly divided into whole corn silage group and corn silage without corn ear group.The feeding effects of the two groups was compared and analyzed.【Result】The average daily gain was 1350 g for the whole corn silage group,which increased 320 g compared with the corn silage without corn ear group.The difference was significant(P0.05).During the experiment period,the net income in whole corn silage group increased 175.2 yuan compared with corn silage without corn ear group.And the difference was significant(P0.05).【Conclusion】The corn straw had good nutrition value and palatability by silage processing,especially silage with whole corn.The feeding effect by whole corn silage was better than general silage,which could improve weight gain rate and economic benefit.The feed intake was also increased and the feed reward was high.As to the larger scale beef cattle farm,whole corn silage could be vigorously popularized and applied in the future.
