BACKGROUND The study aimed to evaluate the effect of Lactobacillus casei TH14, cellulase, and molasses combination fermented sugarcane bagasse (SB) as an exclusive roughage source in the total mixed ration (TMR) for mid‐lactation 75% crossbred Holstein cows on feed intake, digestibility, ruminal ecology, milk yield and milk composition. Four multiparous mid‐lactation crossbred (75% Holstein Friesian and 25% Thai native breed) dairy cows of 439 ± 16 kg body weight, 215 ± 5 days in milk and average milk yield 10 ± 2 kg d −1 were assigned to a 4 × 4 Latin square design. The unfermented SB (SB‐TMR), SB fermented with cellulase and molasses (CM‐TMR), SB fermented with L. casei TH14 and molasses (LM‐TMR), and SB fermented with L. casei TH14, cellulase and molasses (LCM‐TMR) were used as dietary treatments. RESULTS CM‐TMR, LM‐TMR and LCM‐TMR significantly ( P < 0.01) increased dry matter and fiber digestibility, gross energy and metabolizable energy intake ( P < 0.05), blood glucose, total volatile fatty acids ( P < 0.05), propionic acid and milk yield, but decreased ammonia, acetic acid, acetic:propionic ratio and methane production ( P < 0.05) when compared with the SB‐TMR. Compared with fermented SB treatments, LCM‐TMR had lower ( P < 0.05) ruminal ammonia and greater blood glucose ( P < 0.01); LCM‐TMR showed ( P < 0.05) greater volatile fatty acids, propionic acid, milk yield and total solids, and lower acetic:propionic ratio ( P < 0.01); methane, protozoa and somatic cell count were found to be lowest in LCM‐TMR. CONCLUSION Combination of L. casei TH14 and additives (LCM‐TMR) effectively enhanced feed use, rumen ecology and milk production of Holstein Friesian cows. © 2021 Society of Chemical Industry
