Abstract
This experiment was conducted to study the effects of growth stage and variety on the quality of whole crop rice(WCR) silage at National Institute of Animal Science, RDA from 2004 to 2005. Two types of rice("Chucheong" for food and "Hamasari" for whole crop) were harvested at six different growth stages (heading, flowering, milk, dough, yellow ripen and fully ripen stage) and ensiled each harvest stages. Crude protein(CP) content of all whole crop rice silage was also decreased with progressed maturity at harvest and TDN(total digestible nutrient) content of WCR was increased. The average CP content of whole crop rice was higher than that of food rice. The contents of ADF(acid detergent fiber) and NDF(neutral detergent fiber) decreased with delayed harvest maturity. The content of TDN estimated from ADF content was increased with progressed maturity, but there was not found significant difference between rice varieties(p<0.05). The average pH value was 4.69 and it was increased with delayed harvest maturity. Acetic and butyric acid content were decreased, but lactic acid content was increased with progressed maturity. The experiments presented here show that all rice varieties may give a good quality silage. But some wrong practical method(grain loss, productivity, nutrient value, etc.) will make poor quality of rice silage. Therefore, dough stage of harvest maturity will be recommendable as proper harvest time for making high quality of whole crop rice silage in Korea.
