摘要：Objective: This study was aimed to evaluate the effect of different feeding methods on feeding behavior, feed intake and digestibility of lactating dairy cows. Methodology: Fifteen first-lactating Friesian-Holstein dairy cows in the third month lactation with an average of 515±61.5 kg b.wt., were used as the experimental animals. The cows were subjected to three different feeding methods namely Component Feeding (CF), cafetaria (cafe) and Total Mixed Ration (TMR) according to a completely randomized design with five replicates. Results: Results demonstrated that treatment affected (p<0.05) single meal time; afternoon feeding frequency and nocturnal rumination frequency, but did not affect rumination time during one day, in the afternoon and evening; single rumination time in 1 day and in the afternoon and afternoon rumination frequency. Digestibility of dry matter , organic matter and energy were not affected by treatments. Conclusion: Conclusively, lactating dairy cows fed with cafeteria feeding pattern took longer single meal time and less frequent afternoon feeding, while the component feeding take one time rumination and longer rumination in standing position and the total mixedration had more frequent daily and nocturnal rumination. The strategy of feeding with TMR resulted in a lower chewing time, tended to decrease feed intake but increase feed digestibility.
