Abstract

This experiment was conducted to study the effects of forage combinations on nutrient digestibility, utilization of energy and nitrogen of diets for dairy cows. A single factor random block was used in this study. Sixteen Holstein cows were divided into four groups with four heads in each group. Four diets of different combinations were designed with common forages. The results showed as follows: the digestibility of dry matter, organic matter and neutral detergent fibers of diet D was the highest, and was significantly higher than that of the other diets (P<0.05), followed by diet B and diet C; that of diet A was the lowest, and was significantly lower than that of the other diets (P<0.05); no significant difference was detected in the digestibility of acid detergent fibers (P>0.05). There were significant effects of forage combinations on gross energy intake (GEI), digestibility and metabolic rate of energy (P<0.05), and the methane energy/gross energy intake (CH₄-E/GEI) of diet D was significantly lower than that of the other diets (P<0.05). There were no significant differences in the percentage of fecal nitrogen or urinary nitrogen in total nitrogen intake among different diets (P>0.05). Nitrogen digestibility of diet D was significantly higher than that of the diet B and diet C(P<0.05), and that of diet B was also significantly higher than that of diet A (P<0.05); meanwhile, nitrogen utilization of diet D and diet B was significantly higher than that of diet A (P<0.05). In conclusion, nutrient digestibility, utilization of nitrogen and energy of the diet compounded with corn silage, alfalfa hay and Chinese wildrye are better than those of diet with the other combinations, and there are positive combination effects between corn stover and Chinese wildrye, which can improve nutrient digestibility and utilization of energy and nitrogen.

Key words： forage combination; digestibility; energy utilization; nitrogen utilization; dairy cows
