Description
The main goal of this research was to evaluate the effect of functional trimming applied at the dry off period over milk production and reproduction of cows. The study was done on 47 Brown Swiss cows with two or more calving. The animals were divided randomly in two groups. The functional trimming technique was applied to the experimental group while the other group was kept as control. The observation were done basically over the reproduction parameters as claving interval-first service, calving-conception and numbers of breeding required per conception. The results indicate that milk production in the control group decreased 2.88 liters per cow/day in the first four month of lactation. The observations on reproductive parameters shows that the interval from calving to first service increased by 40.5 days and the interval from calving to conception increased by 39 days when compared with animals that received the functional trimming at the dry off period. Statistically significant differences were observed (P>0,05). According to the results, it can be concluded that functional trimming at the dry off period improved milk production in the first four months of lactation as well as reproductive parameters in dairy cows.
