摘要
Abstract
Object:The experiment was designed to verify the effect of silage made from byproducts such as ramie stem as roughage to feed beef cattle.Method:We took 6 Xianan cattle as experimental ani-mals, part of concentrated feed was replaced by ramie byproducts silage , weight measurement was con-ducted at different fattening times , back fat thickness ( FT ) , loin eye area ( LA ) , intramuscular fat ( IMF) in vivo was measured by using B -mode ultrasound , and meat percentage was measured after 8 months of fattening.The significant differences of all the final data for each group were analyzed.Result:The weight gain in the first 2 months was slow , the weight gained rapidly in 3-6 months, and the weight gained also slow in last 2 months.The back fat thickness ( FT) was 1.0150 ±0.16221 cm, loin eye area ( LA) was 133.1458 ±5.05979 cm2 , intramuscular fat ( IMF) was 7.9317 ±0.16883%and meat per-centage was 46.6450 ±0.70897%.Conclusion:the use of ramie silage to feed Xianan cattle was feasi-ble, ramie silage could replace part of concentrated feed , and decreased the amount of concentrate feed by 25%, which could reduce feeding costs , this model could be promoted in ramie planting areas.关键词
