Abstract Four wethers were used in a 4 × 4 L atin square design experiment to evaluate in vivo digestibility of total mixed ration ( TMR ) silage with food by‐products for dairy cows, and the ruminal condition and nitrogen ( N ) balance were examined. Five by‐products (i.e. potato waste, noodle waste, soybean curd residue, soy sauce cake and green tea waste) were obtained. Four types of TMR silage were used: control ( C ) containing roughage and commercial concentrate, T1 :20% and T1 :40% containing the five by‐products replacing 20% and 40% of the commercial concentrate on a dry matter ( DM ) basis, respectively, and T2 :40% containing three by‐products (potato waste, noodle waste and soybean curd residue) replacing 40% of the commercial concentrate on a DM basis. The ingredients were mixed and preserved in oil drum silos for 4 months. The TMR silages showed 4.02–4.44% and 1.75–2.19% for pH and lactic acid contents, respectively. The digestibility of DM and neutral detergent fiber, and total digestible nutrient content were higher ( P < 0.05) for T2 :40% feeding than for C feeding. Urinary nitrogen excretion tended to be lower ( P = 0.07) for T2 :40% than for C . The results suggested 40% replacing of commercial concentrate by using the three food by‐products can be most suitable for TMR silage.
