[Objectives] This study aimed to investigate the effects of whole-crop maize silage harvested at different stages on growth and economic benefits of beef cattle. [Methods] A total of 30 Simmental crossbred cattle weighing about 378 kg were randomly divided into three groups, respectively fed for 70 days with wholecrop maize silage harvested at milk stage (Group I), dough stage (Group II) and physiological maturity stage (Group III). Moreover, the cattle in all groups were given the same concentrate diet. [Results] There were significant differences in dry matter, crude protein and neutral detergent fiber between whole-crop maize silages harvested at different stages (P<0.05). The dry matter in Group II and III was significantly higher than that in Group I (P <0. 05). The crude protein content peaked in Group II, up to 6.37%, which was significantly higher than that in Group I (by 12.74%, P <0.05) and Group III (by 9.26%, P <0.05). Starch content significantly increased with the postponing of maize harvest (P <0. 05). The content of neutral detergent fiber in Group I was significantly higher than that in Group II (P <0.05) and Group III (P <0. 05). The average daily weight gain in Group II was 8. 53% higher than that in Group I (P <0. 05) and 3.70% higher than that in Group III (P>0.05). The dry matter intake in Group II was significantly higher than that in Group I (P <0.05) and Group III (P<0.05). There was no significant difference in feed/gain ratio between the groups (P >0. 05). The economic benefit in Group II was the highest, up to 9.99 yuan/day per capita., followed by that in Group III, 9.79 yuan/day per capita, and that in Group I was the lowest, only 8. 03 yuan/day per capita. [Conclusions] The wholecrop maize silage harvested at dough stage has the best quality and produces the highest economic returns for beef cattle. [ABSTRACT FROM AUTHOR] |
