Abstract
Successful development of livestock farms that breed cows with high production capacities such as Simmental and Holstein breeds, an important role of manage genetic breed capacity import into future generations and management factors that constrain improvement of reproductive performance population. Importing a considerable amount of pregnant heifer Simmental and Holstein breeds from Austria, Germany , contributed positively to the addition of milk and meat production in our country. The study was conducted in Bio farm ” Ramilli ” – Shijak – Durres, for the periods 2008-2011. We also included about 150 cows Simmental pure – breed for dual purpose (milk – meat). Birth of a calf annually for cow provides the optimal milk production that can only be achieved with the correct programs to monitor the events of reproduction. To optimize reproductive indicators for genetic capacity utilization cow is aiming in our study. We also included three groups heifer imported from Austria, and approach them in terms of the farm. Production of milk for the first lactationconducted three groups to 4994 ± 936.4, 4123 ± 817.3, 3750 ± 560 proven statistically differences between them ( P< 0:05). Calving interval realized 421.7 ± 73.4, 396.5 ± 42.1, 386.6 ± 43.7 days, the difference proven statistically (P < 0:05). Conception index 2.1, 1.7, and 1.6. Improving reproductive performance in cows with higher milk production capacities, livestock farms achievedthrough unifying control period after calving.
