Abstract
Five Holstein crossbred cows in mid-lactation were used to investigate the effects of rice straw and corn silage as roughage sources on milk production and energy balance. The feed consumed by the cows consisted of 35 corn silage and 65 basal concentrate CS or of 30 rice straw and 70 basal concentrate plus soybean meal RSSBM. The total dry matter intake was similar between RSSBM and CS cows. The milk yield of CS cows was higher than that of RSSBM cows but the FCM yield did not differ because milk fat content tended to decrease in CS cows. Gross energy intake and energy losses in feces urine and heat production did not differ between RSSBM and CS cows. The methane level of CS cows tended to be lower than that of RSSBM cows. The milk energy output of CS cows was higher than that of RSSBM cows. The energy balance milk energy output retained energy of CS cows tended to be higher than that of RSSBM cows. The efficiency of ME for maintenance and production mean: 0.66 was not different between RSSBM and CS cows. The ME requirement for the maintenance of all cows was estimated to be 463 KJ/BW. Corn silage can be used as a high-energy diet source for lactating cows if an appropriate amount of fiber is supplemented.
