Abstract

This study was conducted to evaluate the effect of feeding the whole crop rice silage (WCRS) which partially replaces the imported grass hay crop on the milking performance of Holstein and profitability. Two experimental diets were used according to the traditional practice of dairy farms. The control diet (C) was composed of 13kg/day of mixed hay, 6.8kg/day concentrate, and orchardgrass/bermudagrass hay (1.8kg/day). The treatment diet (T) was composed of 9.6kg/day of mixed hay, 6.8kg/day of concentrate and 2.2kg/day of WCRS. The CP content of the WCRS (4.6%) was lower than orchardgrass (11.3%) and bermudagrass hay (8.4%) due to the harvest being 30days later than the optimum harvest date of rice. The lower intake was observed in T during the entire experiment period which seems to be related to the higher proportion of fiber in rice (p<0.05). No significant difference was found in milk production between C (26.9kg) and T (26.3kg) during the entire experiment period (p>0.05). Also, no difference in milk fat, milk protein, total solids, and milk composition was observed between the two diets. Higher income per head was resulted in T (21,141won) compared to C (21,915 won). These results indicate that the partial replacement of the grass hay by the WCRS can bring the profit to the dairy farm due to the no difference between the control diet and the treatment diet.

홀스타인 착유우에 수입건초 대신 WCRS로 조사료 일부를 대체 급여하였을 때 산유성적 및 수익성에 미치는 영향을 검토하였다. 대조구(C)는 농가 관행 급여방법으로 자가 혼합건초(13kg)와 농후사료(2.6~9.6kg), 오차드그라스 및 버뮤다그라스 건초(1.8kg)를 급여 하였고, 처리구(T)는 자가 혼합건초(9.6kg)와 농후사료(2.6~9.6kg) 및 WCRS (2.2kg)를 급여하였다. 건물수량(DMI)을 기준으로 C에 대한 T의 조사료 대체비율은 20% 였다. CP함량은 오차드그라스 및 버뮤다그라스 건초가 각각 11.3 및 8.4%였고, WCRS는 4.6%로, WCRS에서 낮았다. 이는 벼를 수확적기보다 약 30일정도 늦게 수확한 것에 기인하고 있다. DMI는 비유초기, 중기 및 후기에서 각각 T가 C보다 유의적으로 낮게 나타났다(p<0.05). 유량은 비유초기, 중기 및 후기 모두 처리간 유의적 차이는 없었다(p>0.05). 실험 기간 중 평균유량도 C 및 T가 각각 26.9 및 26.3kg으로 처리간 유의적인 차이는 없었다(p>0.05). 유지율, 유단백 및 총고형물에서 각 비유기 공히 처리 간에 유의적인 차이는 없었다(p>0.05). 두당 조수입은 C가 21,141원, T가 21,915원으로 T에서 다소 높게 나타났다. 유사비는 T가 22.9%로 C의 27.8%보다 낮았다. 이상에서 수입산 건초 대신 WCRS로 20% 대체 급여하여도 산유량 및 유성분에 유의적인 차이가 없으며 수익은 높아 경제성이 있는 것으로 사료된다.
